Why Do Animals Have Different Pupil Shapes?
Animal pupils exhibit a remarkable variety of shapes that reflect ecological needs. Vertical slits in ambush predators sharpen vertical edges, enhancing stereoscopic depth perception, while horizontal bars in grazing prey expand the panoramic field of view along the ground. Larger predators retain round pupils because their steep gaze reduces the advantage of directional blur. In the ocean, cuttlefish display enigmatic W‑shaped pupils whose function remains uncertain.
Physicists Created an Electron 'Catapult' That Moves Particles at 'Extraordinary' Speed
Physicists at the University of Cambridge have observed ultrafast electron transfer in an organic solar cell that occurs in just 18 femtoseconds, driven by a single molecular vibration acting like a catapult. Using a dual‑laser pump‑probe technique, they showed that...
Why Are Humans the only Species with a Chin?
A team led by evolutionary morphologists studied nine chin‑related traits across 15 hominoid species and found that only three show evidence of direct natural selection. Their analysis, published in PLOS One, suggests the human chin is a spandrel—a structural by‑product rather...
A Gene Carried by 99% of Humanity Raises Alzheimer's Risk Dramatically. Could Gene Therapy Correct It?
A new Nature study of 450,000 people finds that the APOE gene, particularly the APOE3 and APOE4 variants, accounts for 72‑93% of Alzheimer’s disease cases, and that 99% of the population carries at least one risk‑increasing allele. Lexeo Therapeutics is...
I Was at Ground Zero for the AIDS Epidemic. RFK's Cuts Could Fuel a New Pandemic, Just when Elimination Seemed...
Robert F. Kennedy Jr., as HHS secretary, slashed $759 million in HIV research grants, eliminated half of the CDC’s HIV‑prevention divisions and redirected oversight to a new agency, jeopardizing a program that had driven new infections down more than 90 %. At...
The First Flying Taxis Could Start Operating in 2026 — Will This New Form of Transport Actually Take Off?
Flying‑taxi pioneers Joby Aviation and Archer plan to debut eVTOL services in Dubai by 2026, marking the first commercial rollout of electric vertical take‑off aircraft. However, regulators such as the FAA and EASA still require extensive certification, with experts projecting...
New AI Image Generator Runs Using 10 Times Fewer Steps than Today's Best Models — and It's Coming to Smartphones...
Researchers at the University of Surrey and Stability AI unveiled Stable Diffusion 3.5 Flash (SD3.5‑Flash), an image generator that creates high‑quality pictures in just four diffusion steps—about ten times fewer than conventional models that need 30‑50 iterations. The compression preserves visual fidelity...
Best Sports Earbuds 2026: For Runners, Swimmers and Other Fitness Enthusiasts
Live Science’s 2026 roundup identifies the top sports earbuds for runners, swimmers, hikers and budget‑conscious fitness fans. The guide highlights CMF by Nothing Buds Pro 2 as the best low‑cost option, Beats Powerbeats Fit for ultra‑secure fit, Raycon Impact for military‑grade...
Diagnostic Dilemma: A Man Went to the Doctor for a Bad UTI and Learned He Had an Extra Kidney
A 31‑year‑old man in Wardha, India, sought care for a severe urinary‑tract infection and was unexpectedly diagnosed with a supernumerary kidney fused to his right kidney, forming a horseshoe shape. CT imaging revealed swollen kidneys and calculi, leading doctors to...
Will the Indus Valley Script Ever Be Deciphered?
The Indus Valley script, composed of hundreds of symbols and typically only five signs per artifact, remains undeciphered after 4,000 years. Scholars lack a bilingual reference like a Rosetta Stone, and debate whether the signs encode language or serve as...
Microplastics that Accumulate in the Body May 'Clog Up' Immune Cells
A new study published in *Immunity* shows that microplastic particles accumulate in macrophages, impairing their ability to engulf microbes and clear dead cells. Experiments in cultured human macrophages and in mice demonstrated reduced clearance of a fungal lung infection and...
1,900-Year-Old Double Scythian Burial in Ukraine Contains Toxic Red Mineral
Archaeologists have identified cinnabar, a mercury‑sulfide pigment, in a 1,900‑year‑old double burial of two Scythian women at the Chervony Mayak site in southern Ukraine. The red mineral, known for its vivid vermilion hue, may have been applied for ritual coloration,...
'Blackwater' Lakes and Rivers in the Congo Basin Are Now Emitting Ancient Carbon Into the Atmosphere
Scientists have discovered that blackwater lakes and rivers in the Congo Basin are releasing carbon up to 3,500 years old, overturning the belief that ancient peat carbon remains locked underground. Measurements from Lake Mai Ndombe, Lake Tumba and the Ruki...
A 'Mass Migration' Of Stars From the Milky Way's Center Could Explain Why There's Life in Our Solar System
Researchers analyzing Gaia data uncovered 6,594 solar‑twin stars—about thirty times more than earlier surveys—most clustered near the Sun. The findings suggest a massive outward migration of stars from the Milky Way’s crowded centre coinciding with the formation of the galaxy’s...
In People with Epilepsy, Sleeping After a Seizure May Trigger More Seizures
A new study of 11 drug‑resistant epilepsy patients found that nights after a seizure are about 24 minutes longer overall, with rapid‑eye‑movement (REM) sleep reduced by roughly 12 minutes and deep slow‑wave sleep intensified. Researchers propose that the brain may...
Making a 'Digital Twin' Of Yourself Could Revolutionize Future Surgeries, Making Medical Procedures Much More Personal
Dr. John Pandolfino at Northwestern Medicine has created a digital twin of the esophagus to guide myotomy surgery for achalasia patients. The virtual model reproduces pressure and motion, runs millions of simulations, and recommends the optimal surgical cut. A 400‑patient...
'It Could Revolutionize, Completely, the Way We Treat Depression': Researchers Are Exploring Promising Immune Therapy for Treating Psychiatric Symptoms
Researchers led by Dr. James Murrough and Dr. Emma Guttman‑Yassky identified the Th2 immune pathway as a contributor to major depressive disorder. Using proteomic profiling and computer modeling, they repurposed dupilumab—an IL‑4 receptor antibody approved for eczema—to target this pathway....
Could Gut Microbes Hold the Secret to Aging Well? A Researcher Unpacks the Emerging Science
The article explains that gut microbiome composition is tightly linked to aging, with older individuals showing reduced diversity and more inflammatory bacteria. Experiments in mice demonstrate that transplanting youthful microbiota can reverse age‑related inflammation, while diet, fiber, and exercise can...
