Using more training data and computational power is meant to make AIs more reliable, but tests suggest large language models actually get less reliable as they grow

A powerful burst of X-rays from a nuclear explosion could be used to stop Armageddon just in the nick of time, a new experiment suggests.

The FDA-approved Alzheimer's drug donanemab is under scrutiny due to concerns about its effectiveness and safety, according to an investigation. The study highlights multiple patient deaths during trials, design flaws, a...

Research shows a strong link between impulsivity, boredom, and stress, with highly impulsive individuals reacting more to boredom by releasing more of the stress hormone cortisol. This physiological response explains why...

Topological protection provides unprecedented robustness of physical phenomena against all kinds of perturbations; but in doing so, it exercises topological censorship by hiding all kinds of interesting and important mic...

A new study has revealed a link between sunlight exposure, physical activity, and depression using wrist-based activity sensors. Over two weeks, researchers found that individuals with depression had lower physical activ...

A new study reveals that moderate-to-severe traumatic brain injuries (TBI) can have long-lasting effects, persisting for decades. Using advanced MRI scans, blood biomarkers, and cognitive tests, researchers found that su...

It seems to be more energy efficient for emus to keep one foot on the ground when running at a moderate pace, and the same may have been true for dinosaurs

A new study shows that the brain may be naturally wired to recognize faces. Researchers found that neurons in the brains of one-week-old chicks, which had never seen faces before, responded to face-like patterns of three...

These dazzling images taken by NASA's Hubble Space Telescope are from the upcoming book Cosmos: Explore the wonders of the universe, which has a foreword by astrophysicist Becky Smethurst

Feedback explores the painstaking science of hair-pulling, and learns that experts have discovered that its effects can range from "hot-burning" to "aching"

Fear of maths has been around for at least a century. Here are some ways to overcome it, says Sarah Hart, professor emerita of mathematics at Birkbeck, University of London

There can be no victory in a war against nature, says Sunil Amrith in The Burning Earth, a must-read history of our environmental crisis

If we want to preserve the dwindling ice in the Arctic, cutting our emissions is no longer enough - we also need to use geoengineering to refreeze this precious ecosystem

What if tech bros ruled the world, asks Asif Kapadia's 2073. This docudrama is captivating and disturbing, but lacks enough heft to stand out

In nature, photosynthesis powers plants and bacteria; within solar panels, photovoltaics transform light into electric energy. These processes are driven by electronic motion and imply charge transfer at the molecular le...

A new study reveals that extracellular vesicles (EVs), tiny bubbles released by cells, play a crucial role in brain development by facilitating specialized cell-to-cell communication. These EVs carry proteins and transcr...

Scientists have uncovered stable patterns of brain activity across more than 300 individuals by reducing the complexity of fMRI data. These shared activity patterns, consistent across participants, may reveal biomarkers ...

In an article recently published in Physical Review X, the ALICE collaboration presented its studies of correlations in the kaon-deuteron and proton-deuteron systems, opening the door to precise studies of the forces in ...

The record-breaking crystal will act as a DNA time capsule that could be used to bring back humanity after our extinction, researchers say. But not everyone is convinced.

Tree ring data reveals the impact a fluctuating jet stream has had on Europe for 700 years - and sheds light on future risks amid our warming planet

Though it was first predicted in the 1930s, chemists have just now managed to create a covalent bond that only uses one electron
