A heated, plant-based foam has been shown to kill weeds as effectively as a commercial chemical spray and may be a safer, eco-friendlier alternative. “It’s really fascinating, it works very well regardless of the weed growth stage,” says Ilias Travlos at the Agricultural University of Athens, who conducted an independent study of the hot foam at two small olive groves in Greece.

Headlights on new US cars may soon leap forward thanks to a little-noticed regulation that took effect in February, allowing cars on American roads to use lights that intelligently adapt their beam brightness and shape in ways that will utterly change our expectations of headlights. It's a change the insurance companies, safety advocates and I have been eagerly awaiting.

A new artificial leaf is light enough to float on water, where it can soak up sunlight and carbon dioxide from air, and use the water below to produce fuels. Researchers at Cambridge University tested their 100-square-centimeter artificial-leaf device outdoors on a river. Depending on the catalyst used, the device either splits water to produce hydrogen fuel, or converts carbon dioxide into syngas, a mix of carbon monoxide and hydrogen that is used to make other fuels like methanol. Fleets of such devices could be deployed on brackish water ponds, canals, and on seas, so as not to compete with land use, they say.

A soft robot made from droplets of a magnetic fluid can break itself up and reconstitute itself later when it encounters obstacles or narrow passages. Researchers say it could be used for targeted drug delivery in the future. Xinjian Fan at Soochow University in Taiwan and his colleagues used droplets of a ferrofluid, in this case magnetic iron oxide nanoparticles suspended in oil, to make a soft robot about a centimetre in size.

According to reports, a sprawling field in rural Wyoming, US, will soon be filled with shipping container-sized Carbon Removal boxes that are capable of pulling a massive amount of CO2 from the atmosphere to help tackle climate change.

Tumor cells are notoriously good at evading the human immune system; they put up physical walls, wear disguises and handcuff the immune system with molecular tricks. Now, UC San Francisco researchers have developed a drug that overcomes some of these barriers, marking cancer cells for destruction by the immune system.

One minute and four seconds after the launch of an uncrewed flight of Blue Origin's New Shepard launch system on Monday, September 12, the rocket suffered an anomaly. Explosive footage shows the New Shepard capsule's solid rocket escape system fire up to safely eject the capsule away from the rocket's first stage.

Scientists in South Korea have managed to get a nuclear fusion reactor to operate a stable plasma for 30 seconds, marking another promising step toward unlimited clean energy. Nuclear fusion, a process that physicists and engineers have been working on for decades, involves merging two atomic nuclei to form one larger nucleus under intense heat and pressure.

Finally, NASA has come up with the news which could possibly be a stepping stone for human life on Mars. A device called MOXIE may help in sustaining human life by producing oxygen. NASA has been exploring Mars’s climate for the past few decades. They, along with SpaceX CEO Elon Musk, have hinted at the possibility of life on Mars.

Norway-based firm World Wide Wind is developing a new type of floating, vertical-axis wind turbine (VAWT) that it believes will radically change, and improve, the way we harness the wind's powers, a report from New Atlas reveals. Their VAWTs employ two sets of contra-rotating blades to produce double the output of today's biggest turbines, the company says.

A facility described by Danish energy firm Orsted as the “world’s biggest offshore wind farm” is now fully operational, with its 165 turbines set to help power in excess of 1.4 million U.K. homes.

Sea Wave Energy Ltd (SWEL) has been working for more than a decade on a floating wave energy device it calls the Waveline Magnet. With several prototypes tested on- and off-shore, the company claims it delivers "ultra low cost," with high output.

Consumers could charge electric vehicle batteries up to 90 percent in ten minutes within five years, far surpassing the best superchargers in existence.

It doesn't take a scientist to understand why trees are so crucial in the fight to curb climate change. They can absorb and store carbon dioxide, a key greenhouse gas. But a Bay Area startup thinks trees can do better. Living Carbon has developed a technique to genetically modify trees that can grow faster, and store more carbon.

The future of environmentally friendly travel might just be here -- and it's Germany that's leading the charge, with the first ever rail line to be entirely run on hydrogen-powered trains, starting from Wednesday.

We’re in a golden age of progress in artificial intelligence. It’s time to start taking its potential and risks seriously.

MIT engineers fabricated a chip-free, wireless electronic “skin.” The device senses and wirelessly transmits signals related to pulse, sweat, and ultraviolet exposure, without bulky chips or batteries.

Scientists believe they found a solution to ripping apart so-called “forever chemicals” - human-made chemicals known as PFAS - which are now believed to be pervasive around the world. “Forever chemicals” don’t normally occur in nature and don’t break down in the environment, posing a risk to human health as well as to wildlife.

Humans tend to take a lot for granted, even something as simple as a breath of fresh air. It’s easy to forget how much our bodies depend on oxygen—until it becomes an invaluable resource, such as aboard the International Space Station. Although astronauts are typically sent to space with stores of necessary supplies, it’d be too costly to keep sending tanks of breathable air up to the station. Instead the oxygen that astronauts rely on for primary life support is created through a process called electrolysis, wherein electricity is used to split water into hydrogen gas and oxygen gas.

Technology on the nanometre scale could provide solutions to move on from the solid-state era. Solid-state computing has had a long run since the 1950s, when transistors began replacing vacuum tubes as the key component of electronic circuits.
