A tunable metasurface can control optical light in space and time, offering a path toward new ways of wirelessly and securely transmitting large amounts of data both on Earth and in space.

Ultrafine particles, UFPs, the smallest contributors to air pollution, hinder the function of mitochondria in human olfactory mucosa cells, a new study shows. The study showed that traffic-related UFPs impair mitochondrial functions in primary human olfactory mucosa cells by hampering oxidative phosphorylation and redox balance.

Chemists have for the first time established how Rembrandt applied special arsenic sulfide pigments to create a 'golden' paint.

Novel porous crystalline solid shows promise as an efficient and durable material for ammonia (NH3) capture and storage, report scientists. Made through a simple reprecipitation process, the proposed organic compound can reversibly adsorb and release NH3 via simple pressurization and decompression at room temperature. Its stability and cost-effectiveness make this material a promising energy carrier for future hydrogen economies.

Using the James Webb Space Telescope (JWST), astronomers imaged a new exoplanet that orbits a star in the nearby triple system Epsilon Indi. The planet is a cold super-Jupiter exhibiting a temperature of around 0 degrees Celsius and a wide orbit comparable to that of Neptune around the Sun. This measurement was only possible thanks to JWST's unprecedented imaging capabilities in the thermal infrared. It exemplifies the potential of finding many more such planets similar to Jupiter in mass, temperature, and orbit. Studying them will improve our knowledge of how gas giants form and evolve in time.

The 166-million-year-old fossils of an adult and a juvenile of the same extinct mammal species reveal that they had longer "childhoods" and lifespans than similar species today

Methane, a potent greenhouse gas, is converted to CO2 by microbes in tree bark, meaning trees are even better for the climate than we thought

When we take a break from exercise, it can feel like we quickly go back to square one. But this isn't the case, and there are various ways to minimise the decline

Today’s Jesus and Mo strip, called “Trump“, came with a short summary: “God wants you to stop projecting your own desires onto him.”

Clearly Mo is a Democrat!  But of course, anybody who wishes that Trump had been killed is morally off the rails, though I’ve heard that from a few people.

A brain circuit discovered in mice could explain why placebo treatments ease pain in people

If the idea of exercise is more attractive than the reality, you aren't alone. But there are ways to train your motivation and develop better habits

To keep long-term moon residents safe from harmful radiation, lunar bases will need to be built several metres under the surface or inside caves or lava tubes

Combining two neural networks has helped researchers predict potentially disastrous collapses in complex systems, such as financial crashes or power blackouts

Rehabilitation robots, first introduced in the 1990s, are just what they sound like – robotics used to aid in regaining function through rehabilitation following an injury. The idea sounds compelling, and the technology has been advancing steadily. But still we have to ask ourselves the question – do they actually help, and what is the evidence? A recent comprehensive meta-analysis and systematic […]

The post The Evidence for Rehabilitation Robots first appeared on Science-Based Medicine.

An orange layer on the tips of Komodo dragons’ teeth may give the enamel extra strength for ripping apart their prey

Researchers are calling for greater protection for basking sharks after a camera on a tagged shark recorded a collision for the first time

In an effort to understand ancient Neanderthal food preparation techniques, researchers butchered five wild birds using flint stone tools and roasted them

Researchers have successfully made super-heavy element 116 using a beam of titanium-50. That milestone sets the team up to attempt making the heaviest element yet: 120.

A prototype device harvests drinking water from the atmosphere, even in arid places.
