Researchers at the National Renewable Energy Laboratory have broken the world record for solar cell efficiency. Reaching almost 40 percent, the new device boasts the highest efficiency recorded for any type of solar cell in real-world conditions.

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.

Scientists adapting stem cell therapies for difficult-to-treat tumors have developed a highly efficient off-the-shelf approach that showed "profound efficacy" in mouse models of aggressive brain cancer, laying the groundwork for clinical trials.

A new study from scientists in Japan and the US has identified a form of inter-neuron communication as a key mechanism in the way inflammation spreads between joints in conditions like rheumatoid arthritis.

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.

Boeing is back in the business of human spaceflight after its uncrewed CST-100 Starliner passenger spacecraft successfully docked with the International Space Station (ISS) at 8:28 pm EDT, fulfilling the key objective of Orbital Flight Test-2 (OFT-2).

The 45-year-old Voyager 1 deep space probe is showing its age as NASA engineers try to determine why it is sending back invalid telemetry data from its attitude control system as it hurtles through interstellar space, never to return.

NASA has released a huge new report that astronomers are calling Hubble’s magnum opus. Analyzing 30 years of data from the famous space telescope, the new study makes the most precise measurement yet of how fast the universe is expanding.

A huge chunk of energy usage goes towards heating and cooling homes and buildings, so it’s important to find new ways to regulate temperature passively. A new wood-based foam could drastically cool buildings to a degree that can be easily tuned.

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.

How exactly kidney cells transport blood through the organ's tubes has remained a mystery. Now researchers at Johns Hopkins University have investigated the mechanical forces at work and found a previously unobserved pumping action by kidney cells.

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.

The US Department of Energy's efforts to combat climate change are set to receive a massive cash injection, with the Biden administration announcing US$3.5 billion in funding for regional direct air carbon capture hubs to help reach net-zero by 2050.

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 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.
