Scientists warn that the Trump administration's push to dismantle a vital network of ocean-sensing instruments will stymie crucial weather and climate monitoring in the Pacific and Atlantic

Scientists have successfully tested an AI-designed universal coronavirus vaccine in humans for the first time, finding it to be safe and well tolerated. The vaccine generated immune responses against multiple coronaviruses, including SARS-CoV-2, SARS, and related bat viruses with pandemic potential. By targeting features shared across an entire virus family, it aims to provide protection even as viruses evolve.

Did you spot the elk calf in Matthew Hill’s photo this morning? Here it is!

When I asked Matthew how, in the tagging process, he found the hidden calves, he replied:

Typically the cow has a vaginal insert transmitter that comes out when the calf drops, which allows us to pinpoint the birth location. Several hours later the cow and calf move a short distance off the birth location where the calf conceals itself. Say, within 50-500 m. When we arrive, the cow leaves the area but will come back within 4-5 hrs. We systematically survey the area looking for it. Really hard game of hide and seek!

Example of an “activated” vaginal insert transmitter (“vit”) recovered at birth location.

More photos from the tagging process:

 

More: a wolf attacked another calf, but mom apparently drove it off. Matthew:

I’ve attached pics from yesterday of a five day old calf that survived a wolf attack only hrs before we arrived. Very lucky calf.  It must have been a single wolf, and the cow was able to fend it off. If two or more wolves, the cow would have bailed to live to breed another day.

The modern world depends on open-source software maintained by volunteers, but the added demands of checking and fixing AI-written submissions are causing some to burn out and quit

Mice that contain cells with an added rat chromosome have been created by scientists. The next step is to try this with frozen elephant tissue – and if that works, the team will try it with frozen mammoths

Reader Matthew Hill sent some photos taken during his tagging of elk calves (Cervus canadensis), and one of them qualifies as a “spot the. . . ” photo.  Can you spot the elk calf, hiding from predators inconspicuously?  The reveal will be at 10:30 Chicago time, along with other photos from Matthew’s endeavor. His words are indented:

I’m currently involved in tagging elk calves in northern Wisconsin. I thought one of today’s tags might be a fun one for an I spy post. Not super difficult.  It’s a two-day- old female.

Can you spot it?  You can tell us in the comments if you did, but please don’t say where it was. Again, reveal is at 10:30 a.m.  Click the photo to enlarge it.

 

The Jesus and Mo artist tells us that this strip is “a Friday flashback from 13 years ago today”.  The boys abhor homosexuality, but are obsessed with it (remember, they share a bed):

Scientists have proposed a new method for finding tightly bound supermassive black hole pairs by searching for stars that flash repeatedly as their light is magnified by the black holes’ gravity. The timing and brightness of these bursts could provide a unique fingerprint of black holes slowly spiraling toward a future collision.

Scientists have uncovered a surprising force that may help explain how binary star systems form so quickly. New supercomputer simulations show that magnetic fields surrounding newborn stars can act like a cosmic brake, stripping away angular momentum and allowing two still-forming protostars to spiral closer together instead of drifting apart.

Scientists have uncovered unexpected quantum complexity inside cobalt, a metal long thought to be fully understood. Advanced measurements revealed a dense network of topological electronic states that remain robust at room temperature. These states enable extremely fast electron behavior and can be switched or controlled using magnetism. The discovery could open new paths toward next-generation computing and spin-based devices.

A seemingly simple set of rules kicks off a kind of mathematical magic trick, which has kept great minds busy since the 1930s. Columnist Jacob Aron explores the origins of the Collatz conjecture, why it is so addictive to mathematicians and whether AI could help us solve it once and for all

Countless millions of Americans prioritized their health and protecting their neighbors over an imagined return to normal in 2020. Our sacrifices deserve recognition and gratitude, not amnesia and revisionist history from sheltered political scientists.

New studies suggest consciousness can't be judged solely by behavior, whether it's a chatbot discussing philosophy or a bee searching for nectar. Researchers are increasingly focusing on the internal mechanisms of brains and computers, concluding that today's AI is likely not conscious while leaving open the possibility for both conscious insects and future machines.

Astronomers have developed a technique that allows them to detect cloud cycles on distant exoplanets. Using data from the James Webb Sapce Telescope (JWST), the astronomers found that mornings and evenings on the gas giant WASP-94A b have extremely different weather patterns: mornings are riddled with sand clouds, while the skies are clear in the early evenings. By isolating the clouds, researchers can more accurately measure a planet’s atmosphere and provide a clearer picture of the planet’s composition. WASP-94A b, for example, has much less oxygen and carbon than astronomers perviously calculated, making its atmosphere much more like Jupiter than they had originally thought.

New research shows how unmagnetized worlds like Mars can still deflect some of the Sun's solar wind. Unlike magnetospheres that form around planet's like Earth, this effect takes place in Mars' ionosphere. It's called the Zwan-Wolf effect, and it's not clear how deep into the atmosphere it operates.

Scientists using the Euclid space telescope found a red-dwarf brightness “gap” in the population of a globular cluster—an ancient, crowded collection of stars. A similar gap was detected by the Gaia observatory in nearby stellar populations, but it has never before been seen in a globular cluster.

Parents report loving their partners less within the first year of having a child, but that doesn't mean the feeling is permanent or inevitable

A patch of ocean south-east of Greenland is the only place on Earth that is cooling, and it could be a sign that the warm water "conveyor belt" in the Atlantic is slowing down

Researchers at EPFL have developed a chip-scale ultrafast laser that performs on par with traditional tabletop femtosecond lasers. The innovation could make advanced laser technologies far smaller, cheaper, and more accessible for applications ranging from medical diagnostics to atomic clocks.
