A sweeping global report finds that migratory freshwater fish are in steep decline, with populations down roughly 81% since 1970. These species depend on long, connected rivers, but dams and human pressures are cutting o...

Using a smartphone with long nails can be frustrating, forcing people to awkwardly tap with their fingertips instead of their nails. Now, researchers are working on a clear nail polish that could change that by turning f...

A new study shows that sleep timing is the "lever" for teen heart health. Night owls eat more calories and move less, especially during the school year when their internal clocks clash with early start times.

Researchers extracted DNA from a Neanderthal bone fragment found in Russia's Denisova Cave, and the genome is shedding light on how small and isolated their groups were.

A research group from the Technion-Israel Institute of Technology reports in Nature an unprecedented achievement in electron microscopy: the direct measurement of "dark points" within light waves. By doing so, th...

A new study finds that AI chatbots are "sycophants" that affirm users 49% more than humans do. This constant flattery makes users more certain of their own biases and less likely to repair real-world relationship...

High-intensity therapy in the first two weeks after a stroke does not improve hand recovery more than standard care. Natural biological repair seems to dominate the early phase of healing.

From 3D movie screens to augmented-reality devices, many modern technologies rely on our ability to manipulate light. Doing so in a cost-effective and efficient way, however, is often a formidable task. In an article pub...

A female sperm whale has been filmed giving birth for the first time, supported by 10 adult females who lifted the calf out of the water and protected it from predators

The nature of quantum particles has long puzzled scientists. While single-particle interference suggests that a photon can behave like a spread-out wave, a whole photon is only ever detected in one specific place. Tradit...

The ancestor of apes was long thought to come from East Africa, but newly discovered fossils in Egypt may prompt a rethink.

A new study argues that attention impairment, not memory loss, should be the central focus for early dementia diagnosis. The research highlights how "attentional overload" impacts daily life and suggests new ways...

Studying and designing novel materials is a central application of quantum mechanics. Chemists, materials scientists, and physicists focus on subtle interactions in quantum materials and to uncover them they rely on soph...

A new study found that microgravity simulated on Earth hindered sperm cell movement, egg fertilization and embryo development - findings that have serious implications for the future of space colonization.

Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The high-energy collisions produce a shower of subatomic fragments that scientists can then study to rec...

Can a stroke make part of your brain younger? New research using deep learning reveals that undamaged brain regions reorganize and show "youthful" structural patterns to compensate for severe stroke damage.

A 12-week study shows that repeating the same meals leads to greater weight loss. By reducing decision fatigue, "routinized eating" helps people lose 5.9% of their body weight compared to 4.3% for those eating va...

A computer language designed to robustly verify mathematical theorems and expose logical flaws has been turned towards a physics paper - and spotted an error. The discovery raises questions about how many other papers ma...

A 19-year study reveals that mentally active sitting-such as reading or working-can reduce dementia risk, while passive sitting like watching TV increases it. Researchers suggest "swapping" passive habits for act...

Using X-ray lasers, researchers at Stockholm University have been able to determine the existence of a critical point in supercooled water at around -63 C and 1,000 atmospheres. Ordinary water at higher temperatures and ...

Visual experiments suggest just a small fraction of the information our brains process enters awareness. The post What We Actually See-and Dont See-Shows Consciousness Is Only the Tip of the Iceberg appeared first on Sin...

Aging may "erase" the epigenetic markers that control gene expression in the brain, and this may create a snowball effect.
