There are already "smart" windows that can be electronically switched between either letting sunlight through or blocking it. A new multi-layered one, however, can be set to several energy-saving light filtration modes.

Green hydrogen is going to demand a lot of water for electrolysis – nine liters of pure water for every kilogram of hydrogen. Researchers say they've found a simple way to use seawater in standard electrolyzers, and that's big news for clean energy.

In 2017, Japan created a pioneering national hydrogen strategy, envisaging a carbon-neutral "hydrogen society." But a Renewable Energy Institute report slams the policy as catastrophically misguided, with 70% of its 10-year budget "spent on bad ideas."

Using the same whipping siphon used in the culinary world, researchers have created a food-based foam that can be injected directly into tumors. The foam contains oxygen, which makes tumors more susceptible to chemotherapy and radiation treatments.

When it comes to PTSD, much of the clinical research focuses on improving the condition rather than predicting it. However, a new study has uncovered a brain marker that seems to show who is more likely to develop PTSD when exposed to trauma.

While bioengineered skin holds promise for people such as burn victims, the material has so far only been produced in flat sheets. Now, scientists have devised a method of growing it in 3D forms, which could be slipped onto the body like clothing.

Explosions get you much more bang from your fuel buck than combustion – if your engine can withstand them. NASA believes the rotating detonation engine could be the future of deep space travel, and it's getting strong results in prototype testing.

NASA and DARPA have agreed to develop and test a nuclear rocket engine in space as soon as 2027. Using a nuclear reactor as its power source, it would outperform chemical rockets and greatly reduce the time for the first crewed Mars mission.

Astronomers have released one of the biggest data dumps of the Milky Way ever, cataloging an incredible 3.32 billion cosmic objects in detail. The end result is a gigantic image that can be zoomed in and out for a stunning sense of scale.

Researchers have created a new class of robots that can shift between solid and liquid forms on demand. In a series of tests, these new bots could change shape to run obstacle courses, carry objects, or even escape from a jail cell like a Terminator.

Solar panels can’t operate efficiently if they’re caked in dirt, but cleaning them regularly can be a time-consuming process. Engineers in Germany have now developed an ultra-thin coating that can make solar panels and other surfaces self-cleaning.

For some time now, a nanomaterial known as MXene has been touted as a faster-charging alternative to the lithium used in batteries. It could soon be an even more viable choice, as scientists have devised a method of making it last much longer.

Using gene editing, researchers have engineered prairie voles with no oxytocin receptors. These monogamous mammals were thought to rely on oxytocin to form social bonds but new results suggest this "love hormone" may be less important than suspected.

Our ancestors probably didn’t smell good, but did they smell well? A new study has grown odor receptors from Neanderthals and Denisovans, and tested their sensitivities to different smells compared to modern humans.

Not content with the woolly mammoth and the thylacine, Colossal Biosciences has now announced the third animal on its de-extinction list – the dodo. The company has received new funding, and provided an update on its scientific progress so far.

Although the air in our homes or workplaces may seem OK, it might contain harmful compounds emitted by materials like particleboard and carpeting. New research suggests that we may soon be able to tell if that is the case, using tiny glowing worms.

A rare decarbonization idea that looks as good for business as it does for the planet. This system promises to radically reduce carbon dioxide emissions for 70% of steelmakers, while generating profits and making use of existing blast furnaces.

Seeking a passive way to keep buildings cool in hot weather and warmer in the colder months, researchers have developed a new electrochromic shape-shifting material. It switches from solid to liquid and from clear to opaque at set temperatures.

Physicists at Brookhaven National Laboratory have discovered a completely new type of quantum entanglement, the spooky phenomenon that binds particles across any distance. This allowed scientists to peer inside nuclei in more detail than ever before.

Dark matter remains elusive despite decades of searching. Now physicists have proposed a new experiment that would try to find signals by sending atomic clocks to where dark matter should be at its most dense – right near the Sun.

Wormholes are a sci-fi staple, and and it's possible that they exist in the real universe. But how would they work? Physicists have now used a quantum processor to simulate a traversable wormhole, teleporting information between two quantum systems.

Some people feel that their food isn't quite tasty enough unless it had added salt, sugar or MSG. The SpoonTEK spoon offers a healthier alternative, as it reportedly boosts the perceived flavor of foods by harmlessly zapping its user's tastebuds.

With a new year comes a new CES, and a new crop of gadgets. Samsung has now revealed its latest lineup of monitors, headlined by the new Odyssey Neo G9, which packs two 4K displays side-by-side in one ultra-wide, curved monitor.

Water is usually something you’d want to keep away from electronic circuits, but engineers in Germany have now developed a new concept for water-based switches that are much faster than current semiconductor materials.

Three teams of scientists have achieved a major milestone in quantum computing. All three groups demonstrated better than 99 percent accuracy in silicon-based quantum devices, paving the way for practical, scalable, error-free quantum computers.

IBM has unveiled the Eagle, the world’s most powerful quantum processor. Boasting 127 quantum bits (qubits), the Eagle is a major step towards commercial quantum computers outperforming traditional machines.

An Australian/German company is developing powerful quantum accelerators the size of graphics cards. They work at room temperature, undercutting and outperforming today's huge, cryo-cooled quantum supercomputers, promising industry-wide disruption.
