Sabra Klein is deeply aware that sex matters. During her PhD research at Johns Hopkins University, Klein learned how sex hormones can influence the brain and behavior. “I naively thought: Everybody knows hormones can affect lots of physiological processes—our metabolism, our heart, our bone density. It must be affecting the immune system,” she says. But…

Matt Kaeberlein is what you might call a dog person. He has grown up with dogs and describes his German shepherd, Dobby, as “really special.” But Dobby is 14 years old—around 98 in dog years. “I’m very much seeing the aging process in him,” says Kaeberlein, who studies aging at the University of Washington in…

The Inflation Reduction Act of 2022, which marks the US’s largest-ever investment in climate and clean energy at nearly $400 billion, is a clear environmental victory. But just how far that funding will go in cutting carbon emissions is yet to be seen, and the results are far less certain that some have claimed. Estimates…

Researchers have used deep learning to model more precisely than ever before how ice crystals form in the atmosphere. Their paper, published this week in PNAS, hints at the potential to significantly increase the accuracy of weather and climate forecasting. The researchers used deep learning to predict how atoms and molecules behave. First, models were…

A bioengineered cornea has restored vision to people with impaired eyesight, including those who were blind before they received the implant. These corneas, described in Nature Biotechnology today, could help restore sight to people in countries where human cornea transplants are in short supply, and for a lower price. Unlike human corneas, which must be…

A full decade has passed since Ellen Pao filed a sexual discrimination suit against her employer, the legendary Silicon Valley venture capital firm Kleiner Perkins. Two years later came the toxicity and misogyny of Gamergate, followed by #MeToo scandals and further revelations of powerful tech-business men behaving very badly. All catalyzed an overdue public reckoning…

A habit called “lateral reading” is a core part of any good fact-checking routine. It means opening up a bunch of tabs and doing multiple searches to verify the facts, source, or claims made in a piece of online information. So it seemed like great news when a new study from Poynter, YouGov, and Google…

Nikhita Singhal’s breath still catches when she talks about how her life changed. A psychiatry resident at the University of Toronto, Singhal says it was using psychedelic drugs—ayahuasca, ketamine, and MDMA—that finally addressed the eating disorder she’d had since she was seven years old. “It was really emotionally and psychologically painful,” she says, recounting a…

We all want to be able to speak our minds online—to be heard by our friends and talk (back) to our opponents. At the same time, we don’t want to be exposed to speech that is inappropriate or crosses a line. Technology companies address this conundrum by setting standards for free speech, a practice protected…

Fifteen years ago, David Glowacki was walking in the mountains when he took a sharp fall. When he hit the ground, blood began leaking into his lungs. As he lay there suffocating, Glowacki’s field of perception swelled. He peered down at his own body—and, instead of his typical form, saw that he was made up…

Machine-learning researchers make many decisions when designing new models. They decide how many layers to include in neural networks and what weights to give inputs at each node. The result of all this human decision-making is that complex models end up being “designed by intuition” rather than systematically, says Frank Hutter, head of the machine-learning…

A new system stopped the deterioration of cells in pig organs one hour after the animal’s death, a finding that suggests cells don’t die as quickly as previously understood. The technology successfully restored blood circulation and repaired damaged cells in the pigs. The research, described in Nature today, could pave the way to making human…

The global outbreak of monkeypox has so far led to more than 24,000 cases in over 80 countries, and the World Health Organization has warned that the window of opportunity to contain the disease and prevent it from becoming endemic outside Africa is rapidly closing. Vaccines represent a potentially crucial measure. Monkeypox vaccines are already…

Europe is sweltering in record-breaking temperatures this week, and across the continent, people are largely trying to cope without air conditioning. Fewer than 10% of households in Europe are air-conditioned. But as temperatures rise, that figure is set to climb. Rising AC use may present new challenges, as most systems are inefficient and produce emissions…
