A physicist has mounted one of the most detailed technical challenges yet against the idea that our universe is a computer simulation, arguing that the energy required to run such a program would ...

Precise electrical stimulation is essential for modern neural interfaces, but unwanted current spread often activates off-target cells and limits resolution. A new microneedle electrode design ...

Artificial intelligence (AI) is transforming how scientists understand proteins—these are working molecules that drive nearly every process in the human body, from cell growth and immune defense to ...

Traces of black carbon in snow can alter the light reaching plants, potentially shifting growth patterns and reshaping ...

Neuromorphic computers modeled after the human brain can now solve the complex equations behind physics simulations — something once thought possible only with energy-hungry supercomputers. The ...

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

The National Science Foundation said management of the machine, used by researchers for forecasts, disaster warnings and pure science, would be transferred to a “third-party operator.” ...

Pentagon’s JHTO has awarded $68 million to six vendors to advance Mach 5+ hypersonic missile tech, focusing on maneuverability and more.

As Canada experiences record snowfall, new research from the University of Waterloo suggests that tiny amounts of industrial pollution trapped in snow can change how sunlight reaches the ground below ...

Metals are made of randomly oriented crystals at the microscopic-length scale. The alignment of the crystal faces creates an infinite number of ...

Scientists discover aloe vera compound could offer breakthrough Alzheimer's treatment. Beta sitosterol shows promising results in computer simulations.

xAI has an initiative (using Tesla AI4 hardware) to create AI that fully emulates human computer work. It will work like ...
