Leaves are impressive machines, converting sunlight, carbon dioxide and water into energy. Cambridge scientists have now created artificial leaves that can float on water, tapping into sunlight above it and water below to efficiently produce fuels.

Some fusion projects aim to create hundred-million degree working temperatures in magnetically confined plasma. The CEO of TAE Technologies tells us his team's aiming for 10 times that temperature, targeting cheaper, easier and safer boron fuel.

The US Inflation Reduction Act is poised to kickstart a global hydrogen revolution. Among the bill's many climate-focused provisions are tax credits that will make American green hydrogen the cheapest H2 in the world, as low as US$0.73 per kilogram.

During long-term battles with cancer or infection, immune cells can become exhausted. Now, researchers have identified a specific molecule that helps certain T cells refresh themselves, which could unlock more effective immunotherapy.

Organ transplants can be life-saving, but matching blood types means many people are left on waiting lists. Cambridge scientists have now demonstrated a technique that could one day make donated organs universal, by converting them to blood type O.

Although there are now a number of skin-worn sensors which identify metabolites in sweat, the technology is limited in what it can detect, plus the sensors often aren't reusable. A new one, however, utilizes a "molecularly imprinted polymer" to be much more useful.

NASA's Space Launch System and Orion spacecraft exited the vehicle assembly building today after clearing some final tests and checks, en route to the launchpad for a maiden, uncrewed journey around the Moon.

Northrop Grumman announces that the war in Ukraine is forcing it to develop a US-designed and manufactured replacement for the first stage of its Antares rocket, which was previously made in Ukraine using Russian engines.

The James Webb Space Telescope keeps breaking its own records for peering deeper into space and time. It's now detected a galaxy candidate about 35 billion light-years from Earth, which if confirmed would make it the most distant galaxy ever found.

Scientists experimenting with next-generation plastics at Finland's University of Turku have developed a self-healing form of the material with some impressive capabilities, most notably an ability to quickly break down after use.

In wastewater produced by the textile industry and others, dye is one of the primary pollutants. A newly developed synthetic polymer is capable of removing that dye from the water, plus it can be cleaned up and reused to treat more wastewater.

In recent years, we've heard about efforts to replace some of the aggregate used in concrete with crumbled used tires. Now, however, scientists have succeeded in producing good quality concrete in which all of the aggregate has been replaced with tire particles.

A new study on fruit flies may help explain why siestas came to be such an important habit in many cultures, revealing a type of brain thermometer that kicks sleep-promoting cells into action as the mercury starts to climb.

By combining cutting-edge digital modeling with analysis of a rare, one-of-a-kind fossil, scientists have managed to piece together the first 3D reconstruction of the megalodon, the largest shark to ever live.

Colossal has plans to resurrect the mammoth, and now it's revealed the second species on its de-extinction list – Australia’s lost thylacine. Partnering with a University of Melbourne lab, the project could revive the creature in about a decade.

Scientists know the area in and around the North Pole to be warming disproportionately to the rest of the planet, a phenomenon known as "Arctic amplification." A new study, however, argues that this effect has been vastly underestimated.

One of the best ways to analyze Earth's past climate is with samples drilled from deep ice cores. Now, scientists have dated what may be the world’s oldest ice core, with some sections potentially preserving samples as old as 5 million years.

UC Berkeley chemists say they've created a simple, and very inexpensive way to capture carbon dioxide using a polymer called melamine, that's far cheaper than metal-organic frameworks. It could capture carbon emissions from smokestacks or tailpipes.

Scientists in China have set a new world record for the strongest steady magnetic field ever generated on Earth. The hybrid magnet managed to produce a field measuring 45.22 Tesla (T), which is over a million times stronger than the planet’s own.

Researchers have developed a more precise design for "optical tweezers," using a metasurface lens studded with millions of tiny pillars which focus light to trap and manipulate individual atoms. It could pave the way for powerful quantum devices.

Everything has to end eventually – including the universe itself. It might be hard to imagine a catastrophe big enough to affect the entirety of existence, but here are some of the leading hypotheses about how the universe could end, and when.

While it's definitely not a good idea to record a phone call without the other person's permission, there certainly are times when doing so with their permission could come in handy. The Magmo lets iPhone users do so in what looks like a quick and easy fashion.

Although it's always best to reuse and recycle, many small, simple, low-power electronic devices tend to be single-use. A new paper battery could make them more eco-friendly, as it's activated by water, and it biodegrades once discarded.

While high-end car audio systems do allow users to tweak the various sound frequencies to their liking, the average non-audiophile may get lost in the process. The YourSound system is designed to make things easier, by guiding users via sound samples.

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.
