The Real Mystery About Mexico’s New President

News Feed
Saturday, June 1, 2024

MEXICO CITY — On virtually every corner of Mexico’s capital city, drivers encounter political activists holding signs for one or another of the country’s political parties. Colorful banners enliven the otherwise gray and white walls of the city’s office buildings. The nation is visibly preparing for its presidential election on Sunday.One word dominates, on fences and bumper stickers, even in radio commercials: Morena. It is the acronym of Mexico’s current ruling party, the National Regeneration Movement, which is set to win in the upcoming election.And one person dominates, as well. Next to the party’s dark red logo, Mexicans have grown accustomed to reading the phrase “Es Claudia” — “It’s Claudia” — or “Claudia Presidenta” — “President Claudia.” Those slogans refer to 61-year-old Claudia Sheinbaum, the former mayor of Mexico City and the clear favorite to occupy the nation’s highest office.In fact, the contest is all but decided. Morena, with two allied parties, currently holds a majority of seats in Mexico’s Chamber of Deputies and Senate. It is also the party of Mexico’s current president, Andrés Manuel López Obrador who, despite many controversies throughout his tenure, maintains an approval rating well above 50 percent.As a result, Sheinbaum seems like a virtual shoo-in. Polls give her an ample winning margin of between 15 and 25 percent. Moreover, this spread has remained constant since last September, when Mexico’s largest political forces announced their candidates for the presidency. Sheinbaum is just as popular as her party.So, unless something unexpected were to occur — something that destroys a 20-point lead overnight — Mexicans know what will happen on election day. Millions will head to the polls and around midnight, the president of Mexico’s National Elections Institute will announce Claudia Sheinbaum as the country’s next leader — and the first woman to occupy the presidency.The real question, however, is what will happen after that.For as long as Claudia Sheinbaum has been a public figure, she has alternated between what people here see as two different personalities. On one hand, she’s an accomplished physicist with expertise in environmental science and a reputation for pragmatism. On the other, she’s a long-time leftist activist, a close ally and champion of López Obrador — a divisive figure who came to power promising to represent the lowest echelons of Mexican society and, during his tenure, increased social spending to a historic high while simultaneously attacking Mexico’s system of checks and balances.The question raging here is: Which of Sheinbaum’s two personalities will dominate? Some think she will be Mexico’s Angela Merkel — a scientist by training who will prioritize efficiency over ideology for the nation’s benefit. Others see her as a mere puppet of López Obrador, who will follow in his leftist footsteps, increasing social welfare programs and battling the nation’s Supreme Court.The truth, in all likelihood, is that she will fall somewhere in between. But how that balance is set, the way in which she reconciles these aspects of her life, will define not only Mexico’s future but what kind of president she will be when it comes to negotiating with the United States and its president.In other words, which Claudia — or combination of the two — becomes president will have an outsize influence on the U.S. political landscape at a time when immigration, drug trafficking and trade are all top issues for American politicians.Mexico already plays a disproportionate role when it comes to the U.S. debate over immigration, and having a Mexican president set on defending Mexican sovereignty and other Latin American countries could worsen the U.S. border crisis during a presidential election cycle. But the implications to the U.S. go beyond immigration. A more ideological and leftist Sheinbaum could easily take a nationalist perspective on drug policy and commerce. She could seek more beneficial terms for Mexico in the USMCA negotiations next year or be unwilling to cooperate with U.S. authorities to investigate the increased drug trade of fentanyl. A more pragmatic Sheinbaum, on the other hand, could find compromises when discussing trade, and agree on a middle ground for investigating cartels with U.S. support without risking Mexico’s sovereignty.That means the United States should have a keen interest in figuring out which side of Sheinbaum’s personality will govern her interactions with Washington. And it turns out some key episodes in her past took place in the United States.Mexico today is a democracy with a peaceful transfer of power between parties and broadly successful elections. But this is a fairly recent phenomenon. For most of the 20th century, the country was ruled by a single political party, the PRI, in a unique form of autocracy — one that earned it the nickname of “the perfect dictatorship” from Peruvian Nobel Prize-winning author Mario Vargas Llosa.For close to 70 years, the PRI ruled the country from top to bottom, holding the presidency, governorships and Congress. However, every six years, the party would hold elections and a new generation of politicians would enter its ranks. Dissidents were severely punished. In 1968, as students sought to protect the autonomy of Mexico’s public universities, government forces opened fire on protesters resulting in a massacre and the incarceration of many student activists. This would occur again, in 1971. The people would change over time, but the party wouldn’t and anyone who objected was repressed.That is the Mexico that Claudia Sheinbaum grew up in. Born in 1962, she was the daughter of a small businessman and an acclaimed cellular biologist — both descendants of Jewish immigrants from Europe, although Sheinbaum herself is not religiously observant; she kept an image of the catholic Virgin of Guadalupe on her desk as mayor of Mexico City. Due to her mother’s academic life, Sheinbaum’s family was close to some of the student protesters who were arrested in 1968. Her childhood was divided between studying for exams, reading books, listening to political meetings in Mexico’s nascent left wing and visiting family friends incarcerated under the PRI regime.As an undergraduate in Mexico’s National Autonomous University (UNAM), she majored in physics with a focus on clean energy generation. At the same time, however, she was a core member of the university’s activist community, taking part in the Student Council and leading a number of protests against the regime. She was both Claudia the physicist and Claudia the activist. Even her undergraduate physics thesis had a political dimension; she studied the impact of stoves used by purépecha indigenous communities in Mexico to better understand energy consumption in rural areas.Later, as a Ph.D. candidate, she moved briefly to California where she did research at the University of California, Berkeley, while her then-husband, Carlos Ímaz, pursued graduate studies at Stanford. Even then, away from Mexico, Sheinbaum found an outlet for politics. When Mexican President Carlos Salinas de Gortari visited Stanford’s campus in 1991, she joined protesters holding a sign calling for “Free Trade and Democracy Now” — a moment that would be immortalized on the front page of the university’s newspaper, the Stanford Daily.The truth is that all along, Sheinbaum has been both a researcher focused on her career, and a social activist deeply engaged with Mexico’s left. Upon returning to Mexico after her graduate studies, Sheinbaum joined the faculty at UNAM teaching courses on energy management while joining Mexico’s newly formed Party of the Democratic Revolution (PRD) — a leftist party run by Michoacán governor Cuauhtémoc Cárdenas.In 2000, a then up-and-coming politician ran for mayor of Mexico City with the PRD and won; it was López Obrador. Sheinbaum joined his administration as Secretary of the Environment — her first time in public office.According to a biography of Sheinbaum’s career published ahead of the election, she did that job as a data-driven pragmatist, even as her boss became known as a leftist ideologue. Sheinbaum was in charge of expanding Mexico City’s highways and she did it by building a second roadway above the city’s main arteries — Periférico and Viaducto — to reduce emissions and lower traffic congestion. She was also in charge of building the city’s first metro bus line to expand public transportation, now a staple of Mexico City’s urban infrastructure. As a recent memoir puts it, Sheinbaum was passionate about the technicalities of the projects and impatient with the political maneuvering often needed to get them done.But politics and activism were never far away. When López Obrador ran for president in 2006, she became the spokesperson for his campaign; when they lost the election and claimed political fraud, Sheinbaum organized protests in support of their movement. That was her modus operandi: technical when possible, political when needed.Sheinbaum took a break from politics starting in 2006 when López Obrador’s tenure in Mexico City ended and she became mired in a political controversy involving her then-husband receiving bribes, allegedly in support of the López Obrador presidential campaign. After the scandal, Sheinbaum returned to teaching full time at UNAM and participated as a member of the Intergovernmental Panel on Climate Change (ICPP).It was close to a decade later, when López Obrador created a new party — Morena — that Sheinbaum reentered politics. In 2015, she ran to become borough chief of Tlalpan — one of Mexico City’s 16 districts. Morena was seen as a decidedly leftist party, seeking to “transform” Mexico and put an end to a “neoliberal era.” But after she was elected, she began to make a name for herself as a pragmatist. In 2018, she made a successful bid to become Morena’s nominee for mayor of Mexico City, beating more party-line candidates such as long-time activist Martí Batres. Sheinbaum would go on to win the election by using her pragmatism to attract middle-class voters while supporting the ideological stance of Morena, which appealed to lower-class voters who felt neglected by past administrations.As mayor, at least in the beginning of her tenure, Sheinbaum’s technical nature predominated. Her administration was not marked by the kind of political battles that followed her predecessor, Marcelo Ebrard, who had legalized same sex marriage and decriminalized abortion. Instead, she focused on large infrastructure projects and innovation, meant to improve mobility and decrease carbon emissions. She spearheaded the development of a cableway system, capable of moving 133,000 people every day. She also developed a free wifi program across the city, and began constructing the largest solar park inside of a city — built on top of Mexico’s iconic Central de Abastos market. Quite famously, she worked with people outside of her own party to consolidate her cabinet, including her Secretary of Public Security, Omar García Harfuch, who would later run to replace Sheinbaum as mayor with her blessing.Her tenure, of course, had its difficulties. She had to deal with a number of crises including the sudden collapse of a metro train resulting in the deaths of 26 civilians. But even then, ideology seemed to be an afterthought; a ghost of her activist past.It wasn't until after the 2021 midterm elections that Sheinbaum had to deal with politics more closely. The election resulted in a vote of no confidence against president López Obrador after the COVID-19 pandemic, decreasing his party’s hold on Congress and, in a historical shift, turning nine of Mexico City’s 16 boroughs — many of them run by the left — to the opposition. Soon she was dropping her stance as a technical mayor and once again becoming one of López Obrador’s fiercest defenders.Pre-2021, Sheinbaum held back on attacking Mexico’s autonomous electoral institute, the INE, which President López Obrador has criticized since the 2006 presidential election. After the 2021 midterm election, Sheinbaum joined her mentor and began to tweet against the institute. A similar thing happened when speaking of the main opposition parties: PAN and PRI. Her mentions of the political opposition pre-2021 were scarce; afterwards, she would criticize them for opposing a reform to Mexico’s energy sector, and blasted them as harbingers of inequality. The more political Sheinbaum had emerged once more to defend her party and its leader.Some of that shift likely stemmed from the change between being a mayor to running for president. But it also marked a return of the defining tension of her life.Now, with the election looming, which of Sheinbaum’s personalities will guide her presidency is a hot topic of debate here. One needs only to look at Sheinbaum’s proposed government plan to see the inherent tension between her personas.Some of her proposals are truly technical in nature like creating a program to support women who are victims of violence (Proposal #49) or doubling Mexico’s rail freight capacity (Proposal #71). Others are truly political in nature, such as reforming the nation’s electoral institute and Supreme Court so its ministers and justices are elected by popular vote (Proposals #8 and #98). Both of those were key priorities for López Obrador that he did not succeed in implementing.Nowhere is this tension more evident than in her proposals for the energy sector. On the one hand, Sheinbaum has been vocal that she differs with López Obrador’s reluctance to invest in renewable energies. In fact, Proposal #66 of her government plan is precisely about “supporting an energy transition” towards greener sources. Yet, to do this, she aims to maintain Mexico’s state-owned Petroleum and Electricity companies that have been favored by López Obrador despite their immense debts (Proposals #63-65). So which will it be? A green future or one that invests in state-owned oil? At this point in time, no one can say for sure.Whichever Claudia or combination of Claudias comes to power will determine whether she will seek an open dialogue with the U.S. president or fight with ideological fervor to protect Mexico’s sovereignty. It will determine if Mexico will compete for global investment as dozens of western companies seek to relocate away from China or if Mexico will focus solely on domestic concerns. Will Claudia Sheinbaum follow party-line views and be guided by ideology, or will she follow her technical past?That is the election outcome that Mexicans — and Americans — will learn only after the new president is seated.

School of Science welcomed new faculty in 2024

Eleven new professors join the departments of Biology; Brain and Cognitive Sciences; Earth, Atmospheric and Planetary Sciences; Mathematics; and Physics.

The School of Science welcomed 11 new faculty members in 2024.Shaoyun Bai researches symplectic topology, the study of even-dimensional spaces whose properties are reflected by two-dimensional surfaces inside them. He is interested in this area’s interaction with other fields, including algebraic geometry, algebraic topology, geometric topology, and dynamics. He has been developing new tool kits for counting problems from moduli spaces, which have been applied to classical questions, including the Arnold conjecture, periodic points of Hamiltonian maps, higher-rank Casson invariants, enumeration of embedded curves, and topology of symplectic fibrations.Bai completed his undergraduate studies at Tsinghua University in 2017 and earned his PhD in mathematics from Princeton University in 2022, advised by John Pardon. Bai then held visiting positions at MSRI (now known as Simons Laufer Mathematical Sciences Institute) as a McDuff Postdoctoral Fellow and at the Simons Center for Geometry and Physics, and he was a Ritt Assistant Professor at Columbia University. He joined the MIT Department of Mathematics as an assistant professor in 2024.Abigail Bodner investigates turbulence in the upper ocean using remote sensing measurements, in-situ ocean observations numerical simulations, climate models, and machine learning. Her research explores how the small-scale physics of turbulence near the ocean surface impacts the large-scale climate. Bodner earned a BS and MS from Tel Aviv University studying mathematics and geophysics, atmospheric and planetary sciences. She then went on to Brown University, earning an MS in applied mathematics before completing her PhD studies in 2021 in Earth, environmental, and planetary science. Prior to coming to MIT, Bodner was a Simons Society Junior Fellow at New York University. Bodner joined the Department of Earth, Atmospheric and Planetary Sciences (EAPS) faculty in 2024, with a shared appointment in the Department of Electrical Engineering and Computer Science.Jacopo Borga is interested in probability theory and its connections to combinatorics, and in mathematical physics. He studies various random combinatorial structures — mathematical objects such as graphs or permutations — and their patterns and behavior at a large scale. This research includes random permutons, meanders, multidimensional constrained Brownian motions, Schramm-Loewner evolutions, and Liouville quantum gravity. Borga earned bachelor’s and master’s degrees in mathematics from the Università degli Studi di Padova, and a master’s degree in mathematics from Université Sorbonne Paris Cité (USPC), then proceeded to complete a PhD in mathematics at Unstitut für Mathematik at the Universität Zürich. Borga was an assistant professor at Stanford University before joining MIT as an assistant professor of mathematics in 2024.Linlin Fan aims to decipher the neural codes underlying learning and memory and to identify the physical basis of learning and memory. Her research focus is on the learning rules of brain circuits — what kinds of activity trigger the encoding and storing of information — how these learning rulers are implemented, and how memories can be inferred from mapping neural functional connectivity patterns. To answer these questions, Fan’s group leverages high-precision, all-optical technologies to map and control the electrical charges of neurons within the brain.Fan earned her PhD at Harvard University after undergraduate studies at Peking University in China. She joined the MIT Department of Brain and Cognitive Sciences as the Samuel A. Goldblith Career Development Professor of Applied Biology, and the Picower Institute for Learning and Memory as an investigator in January 2024. Previously, Fan worked as a postdoc at Stanford University.Whitney Henry investigates ferroptosis, a type of cell death dependent on iron, to uncover how oxidative stress, metabolism, and immune signaling intersect to shape cell fate decisions. Her research has defined key lipid metabolic and iron homeostatic programs that regulate ferroptosis susceptibility. By uncovering the molecular factors influencing ferroptosis susceptibility, investigating its effects on the tumor microenvironment, and developing innovative methods to manipulate ferroptosis resistance in living organisms, Henry’s lab aims to gain a comprehensive understanding of the therapeutic potential of ferroptosis, especially to target highly metastatic, therapy-resistant cancer cells.Henry received her bachelor's degree in biology with a minor in chemistry from Grambling State University and her PhD from Harvard University. Following her doctoral studies, she worked at the Whitehead Institute for Biomedical Research and was supported by fellowships from the Jane Coffin Childs Memorial Fund for Medical Research and the Ludwig Center at MIT. Henry joined the MIT faculty in 2024 as an assistant professor in the Department of Biology and a member of the Koch Institute for Integrative Cancer Research, and was recently named the Robert A. Swanson (1969) Career Development Professor of Life Sciences and a HHMI Freeman Hrabowski Scholar.Gian Michele Innocenti is an experimental physicist who probes new regimes of quantum chromodynamics (QCD) through collisions of ultra relativistic heavy ions at the Large Hadron Collider. He has developed advanced analysis techniques and data-acquisition strategies that enable novel measurements of open heavy-flavor and jet production in hadronic and ultraperipheral heavy-ion collisions, shedding light on the properties of high-temperature QCD matter and parton dynamics in Lorentz-contracted nuclei. He leads the MIT Pixel𝜑 program, which exploits CMOS MAPS technology to build a high-precision tracking detector for the ePIC experiment at the Electron–Ion Collider.Innocenti received his PhD in particle and nuclear physics at the University of Turin in Italy in early 2014. He then joined the MIT heavy-ion group in the Laboratory of Nuclear Science in 2014 as a postdoc, followed by a staff research physicist position at CERN in 2018. Innocenti joined the MIT Department of Physics as an assistant professor in January 2024.Mathematician Christoph Kehle's research interests lie at the intersection of analysis, geometry, and partial differential equations. In particular, he focuses on the Einstein field equations of general relativity and our current understanding of gravitation, which describe how matter and energy shape spacetime. His work addresses the Strong Cosmic Censorship conjecture, singularities in black hole interiors, and the dynamics of extremal black holes.Prior to joining MIT, Kehle was a junior fellow at ETH Zürich and a member at the Institute for Advanced Study in Princeton. He earned his bachelor’s and master’s degrees at Ludwig Maximilian University and Technical University of Munich, and his PhD in 2020 from the University of Cambridge. Kehle joined the Department of Mathematics as an assistant professor in July 2024.Aleksandr Logunov is a mathematician specializing in harmonic analysis and geometric analysis. He has developed novel techniques for studying the zeros of solutions to partial differential equations and has resolved several long-standing problems, including Yau’s conjecture, Nadirashvili’s conjecture, and Landis’ conjectures.Logunov earned his PhD in 2015 from St. Petersburg State University. He then spent two years as a postdoc at Tel Aviv University, followed by a year as a member of the Institute for Advanced Study in Princeton. In 2018, he joined Princeton University as an assistant professor. In 2020, he spent a semester at Tel Aviv University as an IAS Outstanding Fellow, and in 2021, he was appointed full professor at the University of Geneva. Logunov joined MIT as a full professor in the Department of Mathematics in January 2024.Lyle Nelson is a sedimentary geologist studying the co-evolution of life and surface environments across pivotal transitions in Earth history, especially during significant ecological change — such as extinction events and the emergence of new clades — and during major shifts in ocean chemistry and climate. Studying sedimentary rocks that were tectonically uplifted and are now exposed in mountain belts around the world, Nelson’s group aims to answer questions such as how the reorganization of continents influenced the carbon cycle and climate, the causes and effects of ancient ice ages, and what factors drove the evolution of early life forms and the rapid diversification of animals during the Cambrian period.Nelson earned a bachelor’s degree in earth and planetary sciences from Harvard University in 2015 and then worked as an exploration geologist before completing his PhD at Johns Hopkins University in 2022. Prior to coming to MIT, he was an assistant professor in the Department of Earth Sciences at Carleton University in Ontario, Canada. Nelson joined the EAPS faculty in 2024.Protein evolution is the process by which proteins change over time through mechanisms such as mutation or natural selection. Biologist Sergey Ovchinnikov uses phylogenetic inference, protein structure prediction/determination, protein design, deep learning, energy-based models, and differentiable programming to tackle evolutionary questions at environmental, organismal, genomic, structural, and molecular scales, with the aim of developing a unified model of protein evolution.Ovchinnikov received his BS in micro/molecular biology from Portland State University in 2010 and his PhD in molecular and cellular biology from the University of Washington in 2017. He was next a John Harvard Distinguished Science Fellow at Harvard University until 2023. Ovchinnikov joined MIT as an assistant professor of biology in January 2024.Shu-Heng Shao explores the structural aspects of quantum field theories and lattice systems. Recently, his research has centered on generalized symmetries and anomalies, with a particular focus on a novel type of symmetry without an inverse, referred to as non-invertible symmetries. These new symmetries have been identified in various quantum systems, including the Ising model, Yang-Mills theories, lattice gauge theories, and the Standard Model. They lead to new constraints on renormalization group flows, new conservation laws, and new organizing principles in classifying phases of quantum matter.Shao obtained his BS in physics from National Taiwan University in 2010, and his PhD in physics from Harvard University in 2016. He was then a five-year long-term member at the Institute for Advanced Study in Princeton before he moved to the Yang Institute for Theoretical Physics at Stony Brook University as an assistant professor in 2021. In 2024, he joined the MIT faculty as an assistant professor of physics.

Incredible close-up of spider silk wins science photo prize

Duelling prairie chickens, a snake-mimicking moth and a once-a-year sunrise at the South Pole feature in the best images from the Royal Society Publishing Photography Competition 2025

Spider silk threadsMartin J. Ramirez/Royal Society Publishing These twisting threads wrapped in thinner, looping strands are the silk of an Australian net-casting spider (Asianopis subrufa), a consummate ambush predator. Instead of building a web and waiting for prey to fall into it, this spider holds its net in its front four legs and throws it over a hapless insect. As this electron microscope image shows, its silk is specially adapted for this unusual hunting technique: it consists of an elastic core encased in a sheath of harder fibres of varying sizes, making it both strong and exceptionally stretchy. The photo, taken by Martin J. Ramirez at the Argentinian Bernardino Rivadavia Museum of Natural Sciences and his colleagues, is the overall winner of the Royal Society Publishing Photography Competition 2025. Jumping prairie-chickensPeter Hudson/Royal Society Publishing The winning photo in the behaviour category shows a fight between two male greater prairie-chickens (Tympanuchus cupido), snapped by Peter Hudson at the Pennsylvania State University. Like many grouse species, males gather at a so-called lek during the breeding season, where they compete for mates by leaping into the air and attempting to strike their opponent. TadpolesFilippo Carugati/Royal Society Publishing Filippo Carugati at the University of Turin, Italy, won in the ecology and environmental science category with this photo of tadpoles, taken during fieldwork in Madagascar. The tadpoles, thought to be the young of a Guibemantis liber frog, are swimming in a gelatinous substance hanging from a tree trunk. Atlas mothIrina Petrova Adamatzky/Royal Society Publishing This image by Irina Petrova Adamatzky, a UK-based photographer, is the runner-up in the behaviour category. It showcases the masterful mimicry of the Atlas moth (Attacus atlas), one of the largest moths in the world, with a wingspan of up to 30 centimetres. The tips of its wings resemble snake heads: a disguise that helps it avoid being eaten by birds. Fog in the Atacama desertFelipe Rios Silva/Royal Society Publishing In Chile’s Atacama desert, stratocumulus clouds drifting in from the coast are a valuable resource. Felipe Ríos Silva at the Pontifical Catholic University of Chile and his colleagues are exploring techniques for catching the fog and turning it into drinking water for communities living in one of the driest places on Earth. Ríos Silva’s photo was the runner-up in the earth sciences and climatology category. South Pole sunriseDr. Aman Chokshi/Royal Society Publishing The return of the sun after six months of darkness at the South Pole is captured in this image by Aman Chokshi at McGill University in Canada, the runner-up in the astronomy category. Chokshi had to heat up his camera and contend with the icy wind at -70°C (-94°F) for several minutes to take a 360-degree panoramic shot of the horizon as the sun rose. He then turned it into a stereographic image resembling a small planet, fringed by a green and purple aurora with the Milky Way above.

The 13 best popular science books of 2025

Women's hidden extra work, positive tipping points and new thinking on autism – there's much to chew on in this year's best reads, says Liz Else

Holiday reading: our pick of the best popular science books of the yearhadynyah/Getty Images The challenge here is clearly highlighted on the book’s cover, where “positive” is coloured a bright shiny yellow. After all, we know how tipping points work – a small change makes a big, sometimes defining, change to a system or state. In climate terms, that could mean, for example, that major ice sheets melt, or the Atlantic Meridional Overturning Circulation collapses. The order in which tipping points happen matters too, says Tim Lenton, who has spent years modelling them. But Lenton is after the positives in this excellent exploration of the possible. Pressure from small groups can galvanise change, he writes. Policy at the governmental level is essential, but usually needs the leverage of such groups, disruptive innovation or economic or environmental shock, he says. There are plenty of other factors that can come into play as forcing agents, including personal agency in the shape of individual behaviour, for example eating less meat or adopting electric vehicles. Science popularisers may seem like a wild card, but Clearing the Air by Hannah Ritchie is a bit of a stealth weapon, since it provides data-led answers on the road to net zero. And it helps us to dismiss nonsense claims, such as that heat pumps don’t work in cold weather, or questions like do wind farms kill birds. On the latter, the answer is yes, they do kill some birds, but that number is dwarfed by the annual kill rate of cats, buildings, cars and pesticides. Nevertheless, wind turbines pose a real threat to some bats, migrating birds and birds of prey. But Ritchie points out how to reduce the risk, such as by painting turbines black, and powering down blades during low wind. Lenton is also a realist, urging us to keep our eye on the bigger picture. It is very hard to imagine a time when burning fossil fuels is seen as backward or abhorrent, he writes, but that is “the nature of tipping points in social norms – what beforehand seemed impossible afterwards seems inevitable”.   What could be more stupid than writing a history of stupidity, asks Stuart Jeffries, author of, er, just such a book. Luckily for him and for us, there is a lot to like in this clever exploration of a slippery subject. After all, what do we really mean by stupidity? Ignorance? Foolishness? Inability to learn? As Jeffries says, stupid is a judgement, not a fact – science can’t measure it, except perhaps negatively, by measuring low IQ scores. Jeffries’s quest to understand stupidity is a historical, political and global take, so we’re off on a great philosophical adventure, through Plato, Socrates, Voltaire, Schopenhauer – and multiple obscure and less obscure thinkers. Also included are various schools of Eastern thinking (Daoism, Confucianism, Buddhism and more), which take a different view from the West, in that the pursuit of intelligence may get in the way of personal development or the enlightenment Buddhists call Nirvana. All in all, there are no signs of stupidity in this delightful and unexpected book.   Most of us will recognise this stream of consciousness running as a background to our lives: “Have the kids had enough protein this week?”; “What bedframe would look good in our bedroom?” and the like. This is “cognitive household labor”, the mental labour that keeps families afloat, and sociologist Allison Daminger says it is “missing from most studies of how we do gender via housework”. It is an excellent point in a book that should receive all the positive reviews it can get. Breadwinners by Melissa Hogenboom is a similar examination, exposing the hidden power dynamics and unconscious cognitive biases shaping our lives. As our reviewer wrote, it makes a compelling, evidence-based case for recognising these imbalances and identifying where and how to correct them. Perfect family reading over the holidays.   Unequal by Eugenia Cheng You might think things are either equal or they aren’t, but for mathematician Eugenia Cheng, some things are more equal than others – in maths and in life. Her clever exploration of the meaning of “equals” helps us grasp its mathematical complexities – and the everyday dangers of assuming, for example, two people who score the same on an IQ test are equally intelligent.   This book offers a fascinating opportunity to see art and science reflect off each other in a richly illustrated tour of artwork about the ocean, starting at its coastlines and ending at its abysses. At school, the book’s author, marine biologist Helen Scales, was asked to choose between following an artistic life and a scientific one. Here she indulges both, aiming to select works that “celebrate the diversity of life in the sea”, and to show how artists and scientists working together have played an important part in describing and recording the biodiversity of our oceans. Drawings still play a key role, as Scales recalls a conversation with an ichthyologist, who knew he would need to use both sketching and scientific skills to achieve a true classification of an odd-looking female deep-sea anglerfish.   Discovering the true state of affairs about women, girls and autism – that the prevalence of autism in this group has been underestimated – can only be good. But for neuroscientist Gina Rippon, it is also bittersweet. In this excellent, state-of-the-art account of autism in girls, she admits that by accepting the mantra that autism was much more common in boys, “I have been part of the problem I’m hoping this book will solve”. One person’s story she shares makes the point. “Alice” was a woman with two young sons – one neurotypical, the elder autistic. She had mental health struggles at university, and after nearly three years of pleading for an assessment, she was finally confirmed to be on the spectrum. Alice’s path had been strewn with diagnoses, including borderline personality disorder with social anxiety. But the light-bulb moment came when she took her son, “Peter”, to his first day at nursery school, anxious to see how he would settle. Peter dived into the melee, as Alice watched, stunned. She told Rippon, “He was a native of the world I had been watching from the outside… He just seemed to automatically… belong.” She realised that she was “looking at what not being autistic meant”.   Earth scientist Anjana Khatwa unites science and spirituality in a gorgeous journey through deep time, a personal view of the world of rocks and minerals. She explains how geology is at the heart of today’s biggest issues, how the field itself isn’t known for its diversity – and the origins of the ivory-white Makrana marble that made the Taj Mahal, among other structures.   What is Barney? Why do we remember the Sycamore Gap? How old is ancient? The answers lie in a truly ambitious, very fat, glorious book of trees, complete with maps, photographs and travel notes. It is built round the unusual idea of setting out in search of the 1000 best individual trees that grow in the towns and cities of Britain and Ireland. The handsome book spun out of Paul Wood’s field trip feels like an appropriately slow way to honour organisms that can live to 3000 years and that shape or are shaped by the places where they grow. Savour during the colder months, while you plan your own tree trip.   To understand orchids, think like a matchmaker, writes Sandra Knapp, a senior botanist at London’s Natural History Museum. She is discussing the reproductive habits of Angraecum cadetti in this book, part of the Earth Day series. This is a clever conceit: take any living thing, describe one species at a given hour across 24 hours, and illustrate it (here the illustrator is Katie Scott). Mushroom Day and Tree Day are also in 2025’s crop; Shell Day and Snake Day are planned for 2026. Knapp introduces flowers from everywhere, of every hue, size and reproductive system. There is a nod to Carl Linnaeus: the European chicory’s blue flowers occupy the 4am time slot, in line with his suggestion to plant them early morning.   Wired for Wisdom by Eszther Hargittai and John Palfrey “Do you need help with that?” Few words are as guaranteed to send a 60-plus adult who seems to be struggling with technology into a rage. How refreshing to find a book prepared to sift science from stereotype in what the authors call an especially “unsettled” research area of older adults and tech. One reason for the authors to weigh in early is that even though older adults are an increasing portion of Earth’s billions, they feel ignored – and subject to negative preconceptions by younger people. A healthy and inclusive society, say the authors, needs this older population on board. Among the book’s great takeaways are that older adults are less likely to fall for fake news or scams. Their use of mobile tech is also rising fast, with the number of over-60s in the US with smartphones rising from 13 per cent in 2012 to 61 per cent by 2021. With such buy-in, can we afford to indulge stereotypes?   The two friends to whom I gave copies of this book when it first came out 10 years ago hadn’t heard of Carlo Rovelli, but they both ended up loving it. Now there’s a special hardback anniversary issue out, to remind us that in a mere 79 pages, Rovelli’s lessons managed to span the theory of general relativity, quantum mechanics, black holes, elementary particles and more. After 10 years of polycrisis, re-reading the final chapter now seems to capture the human dilemma perfectly. An ultra-curious yet dangerous Homo on the brink of self-wrought destruction can still marvel at the world, because, Rovelli writes, “on the edge of what we know, in contact with the ocean of the unknown, shines the mystery and the beauty of the world. And it’s breathtaking.” The ideal gift for anyone you know who hasn’t read it yet, in a lovely new package.

Here's What Makes Someone 'Sexy,' According To Science

Jonathan Bailey was voted People's "Sexiest Man Alive." Experts weigh in on what factors make up attractiveness.

Every year, pop culture fiends dissect (or dissent) People magazine’s selection of the “Sexiest Man Alive.” Many popular celebrities have donned the crown, including Harry Hamlin (1987), Brad Pitt (1995 and 2000), Jude Law (2004), Idris Elba (2018), Michael B. Jordan (2020) and Chris Evans (2022). This year, the magazine tapped actor Jonathan Bailey for the honor.Neil Mockford via Getty ImagesJonathan Bailey has been named this year's Sexiest Man Alive by People.In a 2012 interview about the selection process, editor Julie Jordan told USA Today said the magazine staff takes note of how the general public feels about potential options throughout the year while also asking celebrities for their opinions on the matter. So what makes up this “feeling” that someone is sexy? According to experts, there are several factors ― and they aren’t just physical attributes. In fact, it’s based on an interplay of elements that relate to both nature and nurture, making “sexy” a highly variable adjective.“Sexiness is in the eye of the beholder,” Blanca Cobb, a trained body language expert, told HuffPost. “Some people are drawn to physical attributes of the face, voice can be seen as sexy depending on pitch, tone, and intonation. Someone might find the way another person smells or their aroma as sexy. Additionally, warm, open, confident body language can be a turn-on.”Here’s what else makes a person attractive, according to science:Our biology plays a big role — perhaps even the most influential one.“There are many theories in terms of factors that can enhance level of attractiveness that are surrounded by cultural aspects, such as generational trends and ethnic differences of preferences, evolutionary factors such as ‘curviness’ in women noting fertility, and proximity factors indicting we are attracted to what we see most and what we are exposed to around us,” explained Kelsey Latimer, a psychologist based in Florida. “This suggests that attraction has both biological and learned factors.”When talking about appeal, it’s important to distinguish between traditionally defined “good looks” and “sexiness.” According to Merriam-Webster, the latter term refers to someone who is “sexually suggestive or stimulating, interesting.” Sexiness, it seems, invokes a bodily reaction in the eye of the beholder.Someone might be good-looking, for example, without necessarily eliciting a physical response within the average person. When referring to somebody as sexy, on the other hand, we usually mean that they make us physically tingle, to put it simply. “There are evolutionary theories that help us understand that physical attraction is important because it makes us want to reproduce, which keeps the species alive,” Latimer said. “There are certain physical features of men and women that are seen to be highly associated with fertility that might be sparked on an innate level.”Smell, physical similarity and face symmetry also spark our brain to feel a level of attraction toward someone as well. However, noted the experts, trying to use a “one-size-fits-all” approach when analyzing the topic isn’t right.“The reality is if something were ‘innately’ attractive or not attractive, then trends would never change over time and ‘natural selection’ would have boiled us down into all looking the same,” Latimer said. “There is a lot of variation about what is attractive.”Personality is a huge factor as well.Experts are adamant about this: a person’s character and the way he or she presents him or herself to the world influences the way fellow humans perceive their potential sexiness. “Consider this: have you met someone that you might have considered average in physical appearance and then, after getting to know them, you suddenly realized they have a great smile or beautiful eyes?” Latimer said. “That’s not a coincidence. Personality absolutely can change the initial feeling of attraction for the positive or negative.” Although the staff in charge of crowning the sexiest man alive for People magazine each year may not know the various candidates’ personality traits, perhaps asking fellow celebrities for their opinions is a way to account for the behavioral aspect of sexiness.Cobb goes a step further: not only does she acknowledge that personality traits can affect sex appeal, but specific attributes make a difference. “Confidence in the way one speaks and acts can be appealing,” she noted. “Charisma can captivate someone’s attention because it reflects charm, magnetism, and social intelligence. An undervalued characteristic of sexiness is kindness, which reflects compassion, empathy and sensitivity, where the other person feels cared for and loved, which helps strengthen an emotional connection.”A 2017 study led at Simon Fraser University in British Columbia, Canada, confirms this theory. The researchers analyzed a speed-dating event and noticed that the participants who were considered funny were also rated as more attractive than they were deemed at the start of the date.Our environment also matters.“Trends vary a lot based on time, generation, culture location and age,” said Latimer, adding that what makes men sexy to the eyes of others isn’t necessarily the same thing that adds sex appeal to a woman’s character. Similarly, cultural and geographical differences usually birth a diverse set of standards when it comes to attraction. For example, preferences in the U.S. are generally different in Spain, France, Italy and the Netherlands, Cobb said.What’s important to note is that environmental differences clearly affect what the general population may consider to be a favorable set of traits, making sexiness a pretty subjective characteristic that’s in constant flow. “What is sexy in America today might be what is seen as sexy in Asia tomorrow and vice versa,” Cobb said.So the conclusion? There isn’t one definitive marker for attractiveness; what gives one person a feeling that someone is sexy may be unappealing to another. But, that being said, we can certainly see the argument for Bailey.

Nobel Prize in Economics Awarded for Research on Science, Technology and Growth

Joel Mokyr, Philippe Aghion and Peter Howitt share the Nobel economics prize for work that underlines the importance of investing in research and development

October 14, 20254 min readEconomics Nobel Honors Work Linking Scientific Research to ProsperityJoel Mokyr, Philippe Aghion and Peter Howitt share the Nobel economics prize for work that underlines the importance of investing in research and developmentBy Philip Ball & Nature magazine Joel Mokyr, Philippe Aghion and Peter Howitt, winners of the 2025 Economics Nobel prize. Northwestern University, Patrick Imbert/Collège de France, Ashley McCabe/Brown UniversityThe 2025 Sveriges Riksbank Prize for Economic Sciences in Memory of Alfred Nobel has been awarded to three researchers who have shown how technological and scientific innovation, coupled to market competition, drive economic growth.One half of the prize goes to economic-historian Joel Mokyr of Northwestern University in Evanston, Illinois, and the other half is split between the economic theorists Philippe Aghion of the Collège de France and the London School of Economics and Peter Howitt of Brown University in Providence, Rhode Island.“I can’t find the words to express what I feel,” Aghion said. He says he will use the money for research in his laboratory at the Collège de France.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.The award “underlies the importance in investing in science for innovation and long-term economic growth”, says economist Diane Coyle of the University of Cambridge. “It's great to see the Nobel prize recognize the importance of this topic,” adds innovation policy researcher Richard Jones of the University of Manchester, UK. “It's important that economists understand the conditions that lead to technological progress,” he adds. The winners, says Coyle, “have long been on people’s list of potential candidates”.Old isn’t goldEconomic growth at a rate of about 1-2 per cent annually is the norm for industrialized nations today. But such growth rates did not happen in earlier times, despite technological innovations, such as the windmill and the printing press.Mokyr showed that the key difference between now and then was what he calls “useful knowledge”, or innovations based on scientific understanding. One example is the advances made during the Industrial Revolution, beginning in the eighteenth century, when improvements in steam engines could be made systematic rather than by trial and error.Aghion and Howitt, for their part, clarified the market mechanisms behind sustained growth in recent times. In 1992 they presented a model showing how competition between companies selling new products allows innovations to enter the marketplace and displaces older products: a process they called creative destruction.Underlying growth, in other words, is a steady churn of businesses and products. The researchers showed how companies invest in research and development (R&D) to improve their chances of finding a new product, and predicted the optimal level of such investment.Entrepreneurial stateAccording to economist Ufuk Akcigit of the University of Chicago, Aghion and Howitt highlight an important aspect of economic growth, which is that spending on R&D does not by itself guarantee higher rates of growth: “Unless we replace inefficient firms from the economy, we cannot make space for newcomers with new ideas and better technologies.”“When a new entrepreneur emerges, they have every incentive to come up with a radical new technology,” Akcigit says. “As soon as they become an incumbent, their incentive vanishes” and they no longer invest in R&D to drive innovation.Thus, because companies cannot expect to remain at the forefront of innovation indefinitely, the incentive for investing in R&D coming from market forces alone declines as a company’s market share grows. To guarantee the societal benefits of constant innovation, the model suggests that it is in society’s interests for the state to subsidize R&D, so long as the return is not merely incremental improvements.The work of all three laureates also acknowledges the complex social consequences of growth. In the early days of the Industrial Revolution there were concerns about how mechanisation would cause unemployment of manual workers – a worry echoed today with the increasing use of AI in place of human labour. But Mokyr showed that in fact early mechanization led to the creation of new jobs.Creative destruction, meanwhile, leads to companies failing and jobs being lost. Aghion and Howitt emphasized that society needs safety nets and constructive negotiation of conflicts to navigate such problems.Their model “recognizes the messiness and complexity of how innovation happens in real economies”, says Coyle. “The idea that a country’s productivity level increases by companies going bust and new ones coming in is a difficult sell, but the evidence that that’s part of the mechanism is pretty strong.”Timely messageThis year’s award comes at a time when funding for scientific research is under threat in the United States and around the world. “It’s a very timely message when we’re seeing the United States undermining so much of its science base,” says Coyle. Aghion said, “I don’t welcome the protectionist wave in the US” and added that “openness is a driver of growth. I see dark clouds accumulating”. to translate high-tech innovations into market value.Economic historian Kerstin Enflo, a member of the Nobel prize awarding committee, denied that the award was intended as a comment on the direction of US policies. “It is only about celebrating the work [the laureates] have done”, she said at the press conference.Green growthMore recently, researchers are questioning the ‘growth-at-all-costs’ narrative not least because of the ways to pursue growth has led to environmental degradation, including global warming.“How can we make sure we innovate greener?” Aghion asked. “Firms don’t spontaneously do this. So how can we redirect growth towards green?” Mokyr’s work showed that growth can sometimes be self-correcting in the sense of producing innovations needed to solve such problems. But that is not a given and requires well-crafted policies to nurture innovation without promoting inequality and unsustainability. “We need to harness the productivity potential and minimize the negative effects”, said Aghion.This article is reproduced with permission and was first published on October 13, 2025.
