Scientists have created a programmable optical chip that can slow light on demand, giving engineers far greater control over how optical signals propagate through a circuit. The technology could provide the delays, synch...

Researchers developed a biomimetic taste sensor combining 3D taste bud organoids with custom 200 mu-tall 3D microelectrode arrays.

Researchers developed a high-resolution, adaptive light-sheet microscopy system capable of capturing 3D seizure propagation in live larval zebrafish brains in real time.

A new study proposes that digital media usage alters human focus through a mechanism called "effort recalibration."

By analyzing human-AI interaction through the lens of creative pretense and media theory, the study explains why people readily form emotional bonds and confide in AI companions without attributing moral status to them, ...

Measuring Predictive Age Difference (PAD), the team found that Alzheimers disease and mild cognitive impairment showed the highest accelerated brain aging, followed by psychiatric disorders and substance addiction.

A new study reveals that individuals with psychiatric conditions exhibit reduced flexibility in their brain network dynamics.

The findings demonstrate significant genetic overlaps between BPD and PTSD, depression, ADHD, self-harm, COPD, and diabetes, opening new avenues for transdiagnostic psychiatric research and targeted drug discovery.

A new study establishes childhood unpredictability as a distinct risk factor for youth mental health.

New modeling suggests meltwater from the Greenland ice sheet has a big weakening influence on the Atlantic Meridional Overturning Circulation, but the runoff likely won't cause a complete and irreversible collapse.

Researchers at the University of Michigan have created a device that enables them to control the flow of electrons through a semiconductor using only laser light-no electrical power source required. The device was built ...

On a trip along the Silk Road, columnist Annalee Newitz discovers that ancient technology can offer us a framework for our own advances. The most important drivers of technology arent inventions or devices, it turns out,...

Artificial intelligence faces an energy crisis stemming from a physical traffic jam inside modern computer chips. Processors must continually shuffle data, such as the billions of parameters in complex models, between se...

For more than a decade, mathematicians have been unable to settle the question of whether the ABC conjecture has been solved. Fresh attempts to settle the debate are struggling to make headway

Researchers have developed a new type of optical fiber by freezing a glass capillary filled with liquid. It guides light and sound waves simultaneously and enables highly efficient coupling between them. The high couplin...

The Loki actor is the unlikely host for a three-episode docu-series about the Roman city. It's occasionally a little silly, but it's also entertaining and informative, says Josh Bell

The findings in several foundational brain imaging studies don't hold up in follow-up research.

One of the deepest ambitions in modern physics is understanding how the fabric of space and time could emerge from fundamental quantum degrees of freedom to establish a quantum theory of gravity.

Engineers say an AI image generator built on a new type of physical computing could use far less power than existing stable diffusion-based methods.

Watching television very often in midlife may be linked to troubling brain changes decades later. In a study of about 1,700 adults, frequent TV viewers later showed smaller brain regions involved in memory, decision-maki...

Ancient sediment reveals that some of Kgaris deepest lakes vanished around 7,500 years ago, despite unusually heavy rainfall. The surprising discovery suggests changing winds and future climate shifts could threaten the ...

Chinas Change-6 samples have uncovered a surprising difference between the Moons two hemispheres. Solar wind particles penetrated deeper into the far-side soil because Earths magnetosphere slows the particles that reach ...
