Engineers at UC Davis have built a remarkable device that creates power at night by tapping into something we rarely think about: the vast cold of outer space. Using a special type of Stirling engine, the system links th...

Martin Kamen and Samuel Ruben's discovery of the radioactive isotope carbon-14 in 1940 helped usher in a new era of dating artifacts from past civilizations.

A new method of studying the contents of soil samples has revealed Stone Age people in Sweden were buried in decorated fur-and-feather clothing.

Unexpected rewards can make people move faster in just milliseconds. The findings show that movement vigor mirrors dopamine-based reward prediction signals and could provide a simple way to track brain health in disorder...

Humanitys Last Exam is a PhD-level benchmark designed to test the limits of AI reasoning. Although Googles Gemini 3 scored a staggering 48.4%, experts stress that this does not indicate the arrival of artificial general ...

Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information loss. Physicists have...

Recent decades have witnessed rapid advancements in high-intensity laser technology. The combination of laser irradiation and novel materials is opening exciting avenues for the design of functional materials and devices...

Cigarette smoke doesn't just damage eye cells; it causes epigenetic shifts that "lock" the genes needed to prevent blindness and macular degeneration.

Earlier this week, the number of visible sunspots on our home star fell to zero for the first time in 1,335 days. This normally indicates a period of greatly reduced solar activity, but it's still too soon to relax, ...

A major shakeup to NASA's Artemis program will step rocket launches up to an annual basis, and discard a Boeing-designed upper stage.

As it faces yet another set of delays, NASAs Artemis programme is being shaken up, delaying an actual moon landing in favour of smaller, faster steps forward

Scientists are testing a plastic surgery technique to bypass blocked lymphatic pathways and flush Alzheimer's-linked toxins out of the body.

"Monogenic" diseases, triggered by mutations in just one gene, may actually be more complex than scientists thought.

"At first, I kind of laughed But they were serious. I could just see the seriousness in their faces." In this book excerpt, Lise Barnéoud explores the limitations of DNA testing.

Frailty can typically only be lessened through lifestyle changes, but a stem cell therapy seems to target the underlying causes of the condition, boosting the mobility of frail older people

Neuron-powered computer chips can now be easily programmed to play a first-person shooter game, bringing biological computers a step closer to useful applications

We need to give models knowledge that anchors their behavior to the realities of our world. The post Sparks of Genius to Flashes of Idiocy: How to Solve AIs Jagged Intelligence Problem appeared first on SingularityHub.

While the total lunar eclipse on March 3 is the main event of the month, there's plenty more to see throughout the month of March - here's everything you need to marvel at the night sky this month.

Some solid materials can cool down or heat up when pressure is applied or released. This behavior enables cooling and heating technologies that do not rely on climate-damaging refrigerant gases. In practice, however, a m...

Researchers found that cutting two amino acids common in animal protein-methionine and cysteine-made mice burn significantly more energy. The boost in heat production was nearly as powerful as constant exposure to cold t...

Astronomers have spotted what may be one of the universes earliest barred spiral galaxies - a striking cosmic structure forming just 2 billion years after the Big Bang. The galaxy, COSMOS-74706, dates back about 11.5 bil...

Many cutting-edge technologies, ranging from augmented reality (AR) and virtual reality (VR) to LiDAR (light detection and ranging) systems, rely on components that enable the precise control of light. These components i...
