Under specific conditions, lasers can cool things down – and that might just be what we need to tackle way-too-toasty data centers. A new technology called laser-based photonic cooling can target tiny hotspots on chips to zap heat away.

Sandia National Laboratories (SNL) has shown off the United States' latest nuclear weapon as full production begins seven months ahead of schedule. The B61-13 variable-yield gravity bomb is part of a major program to modernize the American nuclear deterrent.

Asteroids can devastate the planet in an instant – just ask the dinosaurs. Scientists at Sandia National Laboratories have now demonstrated a proof of concept method to deflect a potential Earthbound asteroid using a blast of X-rays.

Researchers have created a molecule that, when added to polymers, increases the material’s durability by making it more able to withstand temperature fluctuations. They say it could be used in everything from plastic phone cases to missiles.

It's long been assumed that when a metal structure like a bridge or an engine develops a crack, it will only get worse over time. But that might not be the case, based on what researchers have just observed happening in a piece of platinum.

Strength and flexibility are two opposites that usually need to be balanced in steel. But now engineers at Purdue University and Sandia Labs have developed a new treatment that can be applied to steel alloys to boost both strength and ductility.

Researchers have used a novel 3D printing technique to create a new superalloy with "previously unobtainable combinations of high strength, low weight and high-temperature resiliency" – and they say the implications in aerospace and energy are huge.

Aeromine says its unique "motionless" rooftop wind generators deliver up to 50% more energy than a solar array of the same price, while taking up just 10% of the roof space and operating more or less silently. In independent tests, they seem legit.

Scientists have developed a way to produce a web of quantum entangled photons using a far more simple setup than usual. The key is a precisely patterned surface 100 times thinner than paper, which could replace a roomful of optical equipment.

As effective as fossil fuels may be, their impact on the planet cannot be overstated. Now researchers at Berkeley Lab have coaxed bacteria into directly producing a new biofuel with an energy density significantly higher than jet fuel.

To keep the lights on in NASA's Artemis human lunar outpost, Sandia National Laboratories is developing electrical micro-grids to handle the power distribution from the Moon base's mini nuclear reactors to the various living and support facilities.

Inspired by seashells, scientists at Sandia National Labs have engineered a versatile new material that’s incredibly inexpensive, strong, lightweight, and heat resistant. The material could find use in shielding for spacecraft or fusion facilities.
