Inside Climate News reports: As global greenhouse gas emissions continue to rise, some climate scientists say it’s time to start paying more attention to the most extreme, worst-case outcomes, including the potential for widespread extinctions, mass climate migration and the disintegration of social and political systems. “Facing a future of accelerating climate change while blind… Read More »
Nature reports: NASA built its state-of-the-art James Webb Space Telescope to peer into the distant Universe and back towards the dawn of time — and it’s already doing so spectacularly. In the two weeks since Webb’s first science images and data became available for astronomers to work with, they have reported a flood of preliminary… Read More »
Jordana Cepelewicz writes: June Huh often finds himself lost. Every afternoon, he takes a long walk around Princeton University, where he’s a professor in the mathematics department. On this particular day in mid-May, he’s making his way through the woods around the nearby Institute for Advanced Study — “Just so you know,” he says as… Read More »
Stephen Buranyi writes: Strange as it sounds, scientists still do not know the answers to some of the most basic questions about how life on Earth evolved. Take eyes, for instance. Where do they come from, exactly? The usual explanation of how we got these stupendously complex organs rests upon the theory of natural selection.… Read More »
Science reports: In June 2021, a jet stream charged with heat and chaotic energy from a nearby cyclone stalled over the Pacific Northwest. The mass of trapped air baked the already hot landscape below to a record 49.6°C. More than 1000 people died from heat exposure. Scientists quickly began working to figure out how much… Read More »
Gizmodo reports: Our liver stays plenty youthful even as we get older, new research this week suggests. Using a form of radioactive dating, the researchers estimate that the average age of our liver’s cells is around three years. Some cells seem to live longer than others, however, a finding that may one day help scientists… Read More »
STAT reports: For nearly two years, as the Covid pandemic disrupted life around the globe, other infectious diseases were in retreat. Now, as the world rapidly dismantles the measures put in place to slow spread of Covid, the viral and bacterial nuisances that were on hiatus are returning — and behaving in unexpected ways. Consider… Read More »
Nature reports: More than 120 confirmed or suspected cases of monkeypox, a rare viral disease seldom detected outside of Africa, have been reported in at least 11 non-African countries in the past week. The emergence of the virus in separate populations across the world where it doesn’t usually appear has alarmed scientists — and sent… Read More »
Matthew Hutson writes: A couple of decades ago, on a backpacking trip in the Sierra Nevada, I was marching up a mountain solo under the influence of LSD. Halfway to the top, I took a break near a scrubby tree pushing up through the rocky soil. Gulping water and catching my breath, I admired both… Read More »
Most of us struggle to think straight after a poor night’s sleep.

Live Science reports: After nearly 13.8 billion years of nonstop expansion, the universe could soon grind to a standstill, then slowly start to contract, new research published in the journal Proceedings of the National Academy of Sciences suggests. In the new paper, three scientists attempt to model the nature of dark energy — a mysterious… Read More »
University of Cambridge and Fudan University: Sleep plays an important role in enabling cognitive function and maintaining good psychological health. It also helps keep the brain healthy by removing waste products. As we get older, we often see alterations in our sleep patterns, including difficulty falling asleep and staying asleep, and decreased quantity and quality… Read More »
Ed Yong writes: For the world’s viruses, this is a time of unprecedented opportunity. An estimated 40,000 viruses lurk in the bodies of mammals, of which a quarter could conceivably infect humans. Most do not, because they have few chances to leap into our bodies. But those chances are growing. Earth’s changing climate is forcing… Read More »
Mathematics is the language of the universe. (Shutterstock) By Peter Watson, Carleton University Almost 400 years ago, in The Assayer, Galileo wrote: “Philosophy is written in this grand book, the universe … [But the book] is written in the language of mathematics.” He was much more than an astronomer, and this can almost be thought… Read More »
Nature reports: As 2021 drew to a close, the highly contagious Omicron variant of the pandemic virus was racing around the globe, forcing governments to take drastic actions once again. The Netherlands ordered most businesses to close on 19 December, Ireland set curfews and many countries imposed travel bans in the hope of taming the… Read More »
Science reports: The Avars, mysterious horse-riding warriors who helped hasten the end of the Roman Empire, dominated the plains between Vienna and Belgrade, Serbia, for more than 2 centuries. Then, they vanished without a trace. Scholars have been searching for their origins ever since. Now, archaeological and genetic evidence reveals the Avars were migrants from… Read More »
