The following essay is reprinted with permission from The Conversation, an online publication covering the latest research. High school sports teams start practices soon in what has been an extremely hot summer in much of the country. Now, before they hit the field, is the time for athletes to start slowly and safely building up… Continue reading How Student Athletes Can Avoid Heatstroke

The Cellular Secret to Resisting the Pressure of the Deep Sea
By the time the molecular part of the project was set to begin, the pandemic had hit. So Winnikoff set up an experiment in his garage. Using a fluorescence spectrometer, he sent rays of ultraviolet light into test tubes filled with small globs of membrane material from the creatures they’d collected. The results puzzled him.… Continue reading The Cellular Secret to Resisting the Pressure of the Deep Sea
Novel Architecture Makes Neural Networks More Understandable
Tegmark was familiar with Poggio’s paper and thought the effort would lead to another dead end. But Liu was undeterred, and Tegmark soon came around. They recognized that even if the single-value functions generated by the theorem were not smooth, the network could still approximate them with smooth functions. They further understood that most of… Continue reading Novel Architecture Makes Neural Networks More Understandable
Can Thermodynamics Go Quantum? | Quanta Magazine
The principles of thermodynamics are cornerstones of our understanding of physics. But they were discovered in the era of steam-driven technology, long before anyone dreamed of quantum mechanics. In this episode, the theoretical physicist Nicole Yunger Halpern talks to host Steven Strogatz about how physicists today are reinterpreting concepts such as work, energy and information… Continue reading Can Thermodynamics Go Quantum? | Quanta Magazine
The Paris Olympics Are a Lesson in Greenwashing
The Summer Olympics will soon begin in Paris against the backdrop of heat waves and drought throughout much of Southern Europe. The organizers of the games say that in light of climate change, they’ve made sustainability a centerpiece of their enterprise. Channeling their inner Greta Thunberg, they promise that the event will be “historic for… Continue reading The Paris Olympics Are a Lesson in Greenwashing
How Did a Landslide Shake the Earth for Nine Days?
No evidence to support any of these ideas was forthcoming. People started jokingly wondering if it was aliens or dragons having a rave or a tantrum. Some sort of leviathan “always comes up” when abnormalities like this baffle seismologists, Hicks said. Three days after the great collapse, the Danish navy surveyed the fjord to chronicle… Continue reading How Did a Landslide Shake the Earth for Nine Days?
China-U.S. Science Collaborations Are Declining, Slowing Key Research
China-U.S. Science Collaborations Are Declining, Slowing Key Research The U.S. and China are collaborating less on projects across scientific disciplines amid a culture of fear in both countries By Gemma Conroy & Nature magazine Manuel Augusto Moreno/Getty Images China’s scientific collaboration with other countries has declined since the pandemic, driven by falling partnerships with the… Continue reading China-U.S. Science Collaborations Are Declining, Slowing Key Research
Major Breakthrough Puts Element 120—the Heaviest Ever—within Reach
New Superheavy Element Synthesis Points to Long-Sought ‘Island of Stability’ A novel way of making superheavy elements could soon add a new row to the periodic table, allowing scientists to explore uncharted atomic realms By Max Springer Jacklyn Gates, head of the Heavy Element Group at Lawrence Berkeley National Laboratory in California, is leading an… Continue reading Major Breakthrough Puts Element 120—the Heaviest Ever—within Reach
Do We Need a New Theory of Gravity?
Observations of the cosmos suggest that unseen sources of gravity — dark matter — tug at the stars in galaxies, while another mysterious force — dark energy — drives the universe to expand at an ever-increasing rate. The evidence for both of them, however, hinges on assumptions that gravity works the same way at all… Continue reading Do We Need a New Theory of Gravity?
Perplexing the Web, One Probability Puzzle at a Time
In late January, Daniel Litt posed an innocent probability puzzle on the social media platform X (formerly known as Twitter) — and set a corner of the Twitterverse on fire. Imagine, he wrote, that you have an urn filled with 100 balls, some red and some green. You can’t see inside; all you know is… Continue reading Perplexing the Web, One Probability Puzzle at a Time
