After years of trying, scientists have finally created a stable superatom of copper, a long-sought-after chemical breakthrough that could revolutionize how we deal with carbon emissions.

Perovskite solar cells (PSCs) are known for their impressive ability to convert sunlight into energy, their low production costs and their lightweight design. They may well be the rising stars of renewable energy, but they ...

Seeing a satellite zip across the night sky can be a fascinating sight. However, what may be spectacular for people on the ground is becoming a major problem for astronomers. A new study published on the arXiv preprint server ...

When spider monkeys want to tell others about the best fruit trees in the forest or ones they've missed, they do so by changing their social groups to share what they know, according to a new study published in the journal ...

Humanoid robots look impressive and have enormous potential to change our daily lives, but they still have a reputation for being clunky. They're also heavy and stiff, and if they fall, they can easily break and injure people ...

Scientists led by a team from Fudan University in Shanghai have created a new flexible fiber chip as thin as a human hair. The development could usher in a new generation of even smarter wearables for a range of applications, ...

For the first time, physicists have generated and observed stable bright matter-wave solitons with attractive interactions within a grid of laser light.

Scientists from China have developed a new way to recycle lithium batteries that is a triple win for the planet. It not only extracts nearly all the lithium for reuse but also traps carbon dioxide and converts the remaining ...

Cancer and Alzheimer's are two of the most common chronic diseases associated with aging. For years, doctors have known about a curious aspect of these two conditions: people who survive cancers are significantly less likely ...

Nature is, of course, the master engineer—been there, seen it, solved it. While we struggle to design buildings that don't overheat or feel like concrete cages, nature has been perfecting comfortable living structures for ...

Lenacapavir (LEN) is an antiviral medication used to treat and prevent HIV/AIDS and was first approved for individuals with drug-resistant infections in 2022. While there is still no vaccine for the virus, the twice-yearly ...

Scientists may have found a new way to spot early signs of obesity, which could lead to novel prevention strategies. A study published in the journal Cell Reports has discovered that people living with obesity have a distinct ...

Prototaxites are something of a prehistoric mystery. They were the first giant organisms on land, towering over ancient landscapes at heights of up to 8 meters. They had smooth trunk-like pillars and no branches, leaves or ...

Most electronics are built on flat, stiff boards, which makes it incredibly difficult to fit them onto curved and irregular shapes we find in the real world, such as human limbs or curved aircraft wings. While flexible electronics ...

Cities are known to shape the evolution of wildlife within them, but according to a study of European cities published in the journal Proceedings of the Royal Society B: Biological Sciences, this is not a one-off event. Rather ...
