A new study shows that DNA forms coils under stress, not the tangled knots that scientists expected.

New research suggests that the tendency of older adults to misinterpret neutral or negative emotions as positive may be a warning sign of cognitive decline. In a study of 665 participants, positivity bias was associated ...

A systematic review of nearly 100 studies found that high-THC cannabis products are linked to negative mental health outcomes, particularly psychosis, schizophrenia, and cannabis use disorder. While some therapeutic rese...

Scientists at Kyoto University have uncovered a hidden protein complex that organizes DNA in sperm stem cells, a discovery that reveals surprising ties between fertility and cancer. When this protein, called STAG3, is mi...

A man who died 12,000 years ago in Vietnam had a "bonus" rib - and it was broken when he was shot by an exotic arrow.

For 40 years, the Big Five personality model has dominated psychology, but new research suggests it may be incomplete. Using taxonomic graph analysis, researchers mapped personality from the ground up, uncovering new met...

New research reveals that primates with longer thumbs tend to have larger brains, suggesting that manual dexterity and brain evolution developed together. The study analyzed 94 living and extinct primate species and foun...

The rare sailback houndshark, which has an unusually large dorsal fin, was first described by scientists in 1973. That was the last record of its existence, until now

Though the technology is embryonic, a new study takes a stab at predicting whether space-based solar could play a role in the energy transition. The post Could a Swarm of Space Mirrors Replace Much of Europes Solar and W...

Scientists have discovered that a toxic complex formed between NMDA receptors and TRPM4 channels drives neuron death in Alzheimers disease. Using a novel molecule called FP802, researchers were able to break apart this d...

New research shows that meaning in life and self-efficacy-the belief in ones ability to succeed-are critical for well-being, regardless of sex. Men reported higher levels of passion and self-efficacy, but both men and wo...

Eye exams could help detect Alzheimers disease years before symptoms arise. By studying mice with a common genetic mutation, researchers found abnormal changes in retinal blood vessels that paralleled brain changes linke...

New research tapping into decades-old concepts is challenging the notion that the only way to treat cancer is to kill every last cancer cell. Instead, scientists suggest, we could try a little persuasion

A person in Maryland has been diagnosed with an infection of the flesh-eating New World screwworm. It's the first case in the U.S. in decades.

Observations from the James Webb Space Telescope reveal unexpectedly high levels of carbon dioxide coming off 3I/ATLAS, giving another clue to the comets origin

Scientists don't know much about the rare bumblebee catfish, native to the rivers of Brazil. One research team was lucky enough to observe thousands of them climbing to scale a waterfall, probably to find opportuniti...

Nearly a decade after they first demonstrated that soft materials could guide the formation of superconductors, Cornell researchers have achieved a one-step, 3D printing method that produces superconductors with record p...

The NIH Baby Toolbox is a groundbreaking assessment system designed to evaluate infants and toddlers development from just 16 days old to 42 months. Using gaze-based learning and tablet-based tools, it allows clinicians ...

Researchers have developed a non-invasive diagnostic tool for Alzheimers disease that measures how the brain regulates blood flow and oxygen. Called the Cerebrovascular Dynamics Index (CDI), it uses Doppler ultrasound an...

Japan's first entirely homegrown quantum computer uses superconducting qubits and components made entirely domestically.

A research team created a plant-inspired molecule that can store four charges using sunlight, a key step toward artificial photosynthesis. Unlike past attempts, it works with dimmer light, edging closer to real-world sol...

Beer is one of the world's most popular drinks, and one of the clearest signs of a good brew is a big head of foam at the top of a poured glass. Even brewers will use the quality of foam as an indicator of a beer hav...
