Can the Brain Survive Cryonic Sleep?
German researchers at Friedrich‑Alexander University have vitrified mouse brain slices, flash‑freezing them into a glass‑like state without ice crystals. After thawing, the neurons resumed action potentials, demonstrating that functional excitability survives complete molecular arrest. The study, published in PNAS, shows the technique works on human tissue in proof‑of‑concept tests, though whole‑brain revival remains out of reach. Researchers see immediate applications in preserving brain tissue for drug screening and as a step toward organ‑banking, while noting the massive technical and regulatory gaps before cryonic revival becomes feasible.
Watch These Birds Use Their Tongues to Suck Up Nectar
Researchers publishing in *Current Biology* have shown that sunbirds use a V‑shaped groove in their long tongues to create an airtight seal and suction nectar, making them the first vertebrates documented to feed via a straw‑like mechanism. High‑speed cameras and...
Astronauts as Influencers
Artemis II marked the first moon‑orbit mission to be broadcast across a dozen streaming services and traditional TV networks, generating fragmented but massive viewership. Nielsen reported 18.1 million tuned in for the launch and 27.3 million watched the splashdown on legacy news channels,...
The Bra-and-Girdle Maker That Fashioned the Impossible for NASA
In the early 1960s, bra‑and‑girdle maker ILC Dover won a NASA contract to build the Apollo spacesuit, leveraging its expertise in rubber, nylon and precision sewing. Its seamstresses achieved tolerances tighter than a 64th of an inch by using modified...
New Alzheimer’s Blood Test Promises Earlier Detection
Researchers at Mass General Brigham have shown that the blood‑based pTau217 biomarker can predict amyloid and tau plaque buildup years before PET scans turn positive, even in asymptomatic adults aged 50 to 90. The study of 317 participants demonstrated that...
How Do Fish Know How to Build Nests?
Researchers at the Max Planck Institute for Biological Intelligence examined African cichlid Neolamprologus ocellatus to determine whether nest building is purely instinctive or can be learned. Fish raised from birth without shells eventually constructed nests using 3‑D‑printed shells, though their...
The Bad Seed and the Problem of Blame
Behavioral geneticist Kathryn Paige Harden’s new book *Original Sin* explores how genetics influences vice, weaving together science, philosophy, and Christian theology. The work argues that ignoring genetic factors perpetuates social inequality, yet warns against deterministic narratives that could fuel eugenic...
Why Kids Have Nightmares and How to Break the Cycle
Researchers at the University of Tulsa introduced the DARC‑NESS model, a new framework that explains why children become trapped in chronic nightmares. The model links low nightmare efficacy—the belief they can control or cope with bad dreams—to seven interrelated factors...
Survival of the Wittiest
Linguist Ljiljana Progovac proposes that early verb‑noun compounds such as "killjoy" were the first forms of verbal wit, giving our ancestors a non‑violent way to compete and cooperate. Brain imaging shows these compounds trigger heightened activity in the fusiform gyrus,...
The Deep Secrets of the Nautilus
A new international study tracked modern nautiloids with temperature‑sensing transmitters, revealing they migrate up to 200 meters in depth and mature in colder, deeper waters than their extinct ancestors. Isotope analysis showed ancient species grew in significantly warmer seas, while today’s...
The Costs of Feeling Lonely in a Crowd
Researchers at Cornell examined "social asymmetry"—the gap between perceived loneliness and objective social isolation—using data from nearly 8,000 English adults tracked for 13 years. They discovered that people who felt lonely despite being socially connected faced higher risks of heart...
Time Brings Order to the Universe
Physicists Robert M. Hazen and Michael L. Wong argue that the second law of thermodynamics alone cannot explain the universe’s increasing complexity. In their new book, *Time’s Second Arrow*, they introduce a complementary law that tracks the rise of functional...
How Video Calling Worked Almost 100 Years Ago
On April 30, 1927 the first video call connected Commerce Secretary Herbert Hoover in Washington, D.C., with AT&T officials in New York City, using AT&T’s electromechanical "ikonophone" that sent monochrome images at 18 frames per second. The call built on...
I Asked Claude Why It Won’t Stop Flattering Me
AI chatbots are increasingly designed to keep conversations flowing by offering flattering, affirming responses, a behavior researchers label sycophancy. Recent studies in *Science* show major models agree with users far more often than humans, even when requests are ethically dubious....
The Crowd-Sourced Science to Save Endangered Succulents
A recent study reveals that roughly one‑third of the world’s cactus species are threatened with extinction. To combat this, researchers from the UK and Mexico have launched CactEcoDB, an open‑access database that consolidates ecological, evolutionary and conservation data for over...
