In a world first, a team at the University of New South Wales has demonstrated measurable power generation from "the inverse of a conventional solar cell." It could eventually produce around one tenth as much power as a solar panel – but at night.

As the number of electronic devices grows, we have to get creative with our energy sources. Cambridge researchers have now demonstrated how an algae energy harvester can use sunlight to power a microprocessor for over a year without any intervention.

Australian company Strategic Elements says it's made a step-change breakthrough in self-charging battery technology that harvests electrical energy from humidity in the air to directly power devices without ever needing to plug them in.

Cataracts are one of the most common forms of vision impairment, and unfortunately surgery is the only real treatment. But the clouds may be parting on a new drug treatment, improving the vision of the majority of mice it was tested on.

Scientists may have unearthed a valuable new tool to study brain injuries, in the form of headbutting animals such as bighorn sheep and muskoxen, in which they've discovered hallmarks of head trauma for the very first time.

The buildup of bacteria deep in our teeth can cause infections in difficult to reach areas, and scientists at the Indian Institute of Science have developed tiny cleaning robots they believe are up to the task.

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.

The field of lunar agriculture has taken a step forward, with scientists reporting the first-ever plants grown in soil from the Moon, marking a significant milestone in the effort to sustain a lunar base and carry out missions into deep space.

Astronomers from the Event Horizon Telescope Collaboration have today revealed the first image of the supermassive black hole at the center of the Milky Way galaxy, produced using a network of radio telescopes around the world.

A new type of desalination membrane uses a series of nanoscale tubes lined with a Teflon-inspired material that repels salts while allowing water to flow through with little friction. The team says it's fast, and requires little pressure and energy.

The production of traditional Portland cement is a major source of greenhouse gas emissions, as the ingredients have to be heated to very high temperatures. Such is not the case with a new biocement, however, which also incorporates waste materials.

While we may think of wood as being earthy and natural, wooden materials such as plywood typically contain formaldehyde-based adhesives that give off toxic fumes. Such is not the case with a new adhesive, which is made from glucose and citric acid.

Last year, we heard how anole lizards are able to breathe underwater from an air bubble on their nose. One of the scientists involved in that study has now documented a spider doing something similar – although the bubble covers its whole body.

Greater mouse-eared bats are preyed upon by owls, but the owls themselves likely avoid hornets, for fear of getting stung. New research suggests that the bats take advantage of this fact, by buzzing like hornets to keep owls at bay.

DNA mutates regularly, for better or worse, driving both evolution and disease. Researchers at the University of Surrey have now found evidence that some of these spontaneous mutations could be caused by the spooky realm of quantum mechanics.

The latest climate change report from the World Meteorological Organization shines the spotlight on some of the important markers of climate change, detailing a string of alarming new records set across 2021.

Rare coral bleaching brought on by abnormal sea temperatures is rapidly becoming the norm on Australia's Great Barrier Reef, which has just experienced its fourth such event in six years, and the first to ever occur in a La Niña year.

The damage sunscreen can do to corals is tied to a common ingredient called oxybenzone, and Stanford scientists have now shown how corals convert the compound into a potent toxin that brings about their demise.

The Large Hadron Collider (LHC), the largest and most powerful particle accelerator ever built, is ready to renter service after a three-year overhaul and refit. On April 22, two proton beams were sent around the the 27-kilometer-long ring.

A collaboration of physicists has made the most precise measurement of the mass of the W boson. The new measurement of this key particle differs drastically from the Standard Model's predictions– and it may unravel physics as we know it.

A team of European researchers has suggested that the Moon’s orbit could be used as a gigantic detector for gravitational waves. These waves, much smaller than those that existing detectors can pick up, could originate from the early universe.

Heat is a major hurdle for electronic devices. Scientists have now found that nanowires made of a certain isotope of silicon can conduct heat 150 percent better than regular silicon, potentially leading to drastically cooler computer chips.

Researchers have now developed the fastest logic gates ever created, by zapping graphene and gold with laser pulses. The new logic gates are a million times faster than those in existing computers, demonstrating the viability of “lightwave electronics.”

A TU Delft team has demonstrated a one-way superconductor that gives zero resistance in one direction, but blocks current completely in the other. The discovery, long thought impossible, heralds a 400x leap in computing speed and huge energy savings.

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.
