Heat maps for each of the five measures of structure mapped to the folded and unfolded surfaces of bilateral hippocampus, averaged across all participants. Cytoarchitectonic subfield boundaries are shown for reference.

The search for early signs of Alzheimer's disease continues: Brain scans reveal microstructural changes in the hippocampus that signal early stages of the disease, including demyelination, increased iron deposition, and changes in water content. In PNAS: https://ow.ly/1NvV50XkXnX

Physicists detect rare 'second-generation' black holes that prove Einstein right... again Physicists have analyzed two enormous black hole mergers that happened one month apart and have come up with tantalizing evidence that rare "second-generation" black holes were involved.

Rare second-generation black holes detected — meaning one black hole once merged and then merged again, confirming Einstein theory yet again ⚫🌠

‘Zombie’ Microbes Redefine Life’s Energy Limits | Quanta Magazine A new model shows that the denizens of a vast, ancient biome beneath the seafloor use barely enough energy to stay alive — and broadens understanding of what life can look like.

In a zombielike biome beneath Earth’s oceans, some individual cells might be 100 million years old.

A House of Dynamite Gets It Right—But Here’s the Full Picture The Pentagon is wrong to attack the movie for being inaccurate. We cannot rely on missile defense systems to protect us from nuclear destruction.

A House of Dynamite shows a scenario where missile defense doesn’t work. The Pentagon calls it unrealistic. Our nuclear expert Dr. Laura Grego thinks the movie gets it right—but the full answer is more nuanced. In her blogs, she explains why. (Alert: contains spoilers).

Greenland is twisting, tensing and shrinking due to the 'ghosts' of melted ice sheets Earth's mantle is so gooey, it takes eons for material that has been displaced by the weight of ice sheets to flow back. And Greenland is very much still processing its glacial past, a new study shows.

The US is unlikely to test nuclear weapons, despite what Trump says President Donald Trump appears to have ordered a return to nuclear testing after decades of uneasy but effective treaties banning the practice – but will it actually happen?

US President Donald Trump has announced his intention to resume nuclear weapons testing after a decades-long ban, but experts tell New Scientist there is little to be gained in doing so.

Neurons don’t work alone, and neither do scientists.

Yiliu Wang’s journey from AI theory to neuroscience at the Allen Institute is a story of collaboration, curiosity, and courage.

Grateful to our new artist-in-residence Refik Anadol for visiting the @alleninstitute.org and sharing his vision for blending art, science, and tech.

His talk was a reminder that data is more than numbers. It can spark curiosity, creativity, and connection. Excited for what’s next. #ScienceMatters

Climate Extremes Are a Hallmark of the Age of Animals | Quanta Magazine New reconstructions of 540 million years of climate history show the planet tumbling between icehouse and hothouse states, revealing how rare and vulnerable our temperate moment is.

Paleoclimatologist Jessica Tierney recently published a global temperature record covering almost the past half-billion years. According to her model, 50 million years ago, inland temperatures approached 122 degrees Fahrenheit.

Lecture slide. Bottom left is a photograph taken through spectral glasses: a slit cut in a piece of cardboard, and spectral lines from an overhead lamp. The slide progresses from there to a picture showing just the spectral lines, now rotated so that blue is left, red is right; then the black-and-white-version, and the right half of the slide is a double image showing a (stretched) version of the spectral lines photograph and below a diagram plotting intensity against wavelength, which is aligned with the stretched-version image and shows maxima where there are bright lines in the image.

Others find peace and calm in knitting, I find it in preparing slides for my astronomy lectures for curious non-physics students :-)

I'm quite pleased with my step-by-step spectroscopy slide, which starts with a "spectral glasses" photo and goes from there to a spectrum-as-diagram. 🧪🔭⚛️

I recently gave a talk on earth science to a group of middle schoolers, and it dawned on me that many of the kids in that age group will be alive to witness what the outcome of Roger Revelle's "great geophysical experiment" looks like in the year 2100.

A small spider with two large, forward facing eyes. He has pale legs and dark brown pedipalps and cephalothorax with three tall spikes of scales on the top. The spider is standing on the side of a pint glass.

Dimorphic Jumping Spiders are a favorite! The male has two forms, one is a grayish body with red, white, and black markings, the other is this handsome fellow with his cool punk-rock spiky tufts. #Arachtober

Astronomer Suspects Mysterious Object Is Up to No Good While It's Hidden Behind the Sun: "If You Want to Take a Vacation, Take It Before Then" Avi Loeb suggested that if 3I/ATLAS is a spacecraft, it may use its proximity to the Sun's powerful gravitational pull while hidden from us.

"It is most energy-efficient for a spacecraft engine to burn its fuel when its orbital velocity is greatest."

Astronomers discover hidden 'moon' shadowing Earth | BBC Science Focus Magazine The space rock has actually been hanging around Earth for 60 years, but no-one has noticed it before... until now.

Earth has a new friend, it turns out. Astronomers have discovered a peculiar “moon” shadowing our planet as it moves through space. Read more from @sciencefocus:
