After about 15 years of diving at the White Sea Biological Station in Russia, marine biologist Alexander Semenov has learned more than most about which jellyfish stings are the worst. If you touch the egg-yolk jellyfish by accident, for example, it is not too bad, he says. And though you should try and stay out… Continue reading See Iridescent Jellyfish and Glowing Wonders of the Sea in World Oceans Day Photos

An Ultra-Precise Clock Shows How to Link the Quantum World With Gravity
The infamous twin paradox sends the astronaut Alice on a blazing-fast space voyage. When she returns to reunite with her twin, Bob, she finds that he has aged much faster than she has. It’s a well-known but perplexing result: Time slows if you’re moving fast. Gravity does the same thing. Earth — or any massive… Continue reading An Ultra-Precise Clock Shows How to Link the Quantum World With Gravity
Landmark Alzheimer’s Drug Approval Confounds Research Community
The US Food and Drug Administration’s (FDA) approval yesterday of the first new drug for Alzheimer’s disease in 18 years was welcomed by some patients looking for hope against an intractable condition. But for many researchers it came as a surprise — and a disappointment. Aducanumab — developed by biotechnology company Biogen in Cambridge, Massachusetts… Continue reading Landmark Alzheimer’s Drug Approval Confounds Research Community
The Disneyfication of Atomic Power – Issue 107: The Edge
John Jay Hopkins’s visit to Japan in 1955, as an informal emissary of “Atoms for Peace,” must have seemed surreal to everyone involved. Hopkins was the head of an old American shipbuilding firm based out of Groton, Connecticut. Electric Boat Company had struggled in the 1920s and 1930s with its reputation as a “merchant of… Continue reading The Disneyfication of Atomic Power – Issue 107: The Edge
Moving silicon atoms in graphene with atomic precision — Mostly Physics
The road from finding to publication is rarely entirely straightforward. As often is the case – but rather too rarely talked about in public – the road from a finding to a publication is rarely entirely straightforward. This was the case for us as well. From the beginning, we felt we had very beautiful results, and furthermore, the agreement that emerged between our detailed simulations and the… Continue reading Moving silicon atoms in graphene with atomic precision — Mostly Physics
Covid, Quickly: A Pop-Up Podcast
COVID, Quickly, Episode 15: Booster Shot Approvals–plus Vaccines for Kids? Today, we’re going to bust through the confusion about booster vaccines: who can get them and who can’t, and we’ll talk about one group that hasn’t even gotten first shots yet: kids under 12. We’ll discuss when that could finally happen. Air date: September 24,… Continue reading Covid, Quickly: A Pop-Up Podcast
How Tadayuki Watanabe Disproved a Major Conjecture About Spheres
In a burst of work, mathematicians have moved closer to understanding just how many ways there are of contorting a simple sphere so that, in the end, it still resembles itself. Much of the progress comes from results by Tadayuki Watanabe at Kyoto University. Over the last several years, he has figured out how to… Continue reading How Tadayuki Watanabe Disproved a Major Conjecture About Spheres
The First ‘Google Translate’ for Elephants Debuts
When a male African savanna elephant folds his ears while simultaneously waving them, he’s ready for a fight. When a female folds her ears and accompanies the action with an ear flap, that means she’s also issuing a serious threat. But when elephants come together and fold their ears while also rapidly flapping them, the… Continue reading The First ‘Google Translate’ for Elephants Debuts
Order Flocking Out of Chaos – Issue 107: The Edge
At first, they trickle in: one bird here, a few birds there. Then, at dusk’s cue, a dark smudge materializes on the horizon. Thousands of starlings (Sturnus vulgaris) slowly come into focus, etching flight paths across the winter sky as they stream toward their evening roost in north-central England. Suddenly, the flock dips and twists… Continue reading Order Flocking Out of Chaos – Issue 107: The Edge
Why India’s Second COVID Surge Is So Much Worse Than the First
India’s relatively mild first wave of COVID last year intrigued scientists and led the country’s leadership to declare what turned out to be a very premature victory over the novel coronavirus. The current surge has been much more deadly. Some researchers and media outlets have pinned the blame on new viral variants, which early studies… Continue reading Why India’s Second COVID Surge Is So Much Worse Than the First
