Researchers have imaged the atoms at the surface of the light-absorbing layer in a new type of next-generation solar cells, made from a crystal material called metal-halide perovskite. Their findings have solved a long-standing mystery in the field of …

Scientists have identified metabolic compounds within the blood that are associated with dementia. The study revealed that the levels of 33 metabolites differed in patients with dementia, compared to elderly people with no existing health conditions. T…

Differences between gut flora and genes from konzo-prone regions of the Democratic Republic of Congo (DRC) may affect the release of cyanide after poorly processed cassava is consumed, according to a study with 180 children. Cassava is a food security …

Using CRISPR, scientists have created a new technology for controlling mosquitoes. The precision-guided sterile insect technique alters genes linked to male fertility and female flight in Aedes aegypti, the species responsible for spreading diseases in…

An international research team with participation of the Paul Scherrer Institute PSI has revealed a secret about a marine animal’s shell: The researchers have deciphered why the protective cover of the brachiopod Discinisca tenuis becomes extremely sof…

Simply by adding sugar, researchers have created a longer-lasting, lighter, more sustainable rival to the lithium-ion batteries that are essential for aviation, electric vehicles and submarines.

Insulin is a key hormone in energy metabolism and blood sugar regulation. Normal insulin function in the body may be disturbed by e.g. overweight, leading to decreased insulin sensitivity and increased risk of developing type 2 diabetes and cardiovascu…

Electrolytic hydrogen production powered by renewable energy is seen as an environmentally friendly means to ameliorate global climate and energy problems. A research team has now introduced a novel and inexpensive material for electrodes that may prov…

Researchers have designed new metasurfaces using nanoscale techniques inspired by kirigami that could offer a new chip-based way to achieve nanoscale control of light, which could lead to better optical displays, information encoding and digital light …

After 20 years of trying, scientists doped a 1D copper oxide chain and found a surprisingly strong attraction between electrons that may factor into the material’s superconducting powers.

Black bears (Ursus americanus) reproduced at a younger age in urban areas and were nearly twice the size of bears in national forests shortly after their first birthdays.

Roadside construction — be it a detour, a closed lane, or a slow weave past workers and equipment — work zones impact traffic flow and travel times on a system-wide level. The ability to predict exactly what those impacts will be, and plan for them, …

Greenland may be best known for its enormous continental scale ice sheet that soars up to 3,000 meters above sea level, whose rapid melting is a leading contributor to global sea level rise. But surrounding this massive ice sheet, which covers 79% of t…

Scientists have found a new chemical process to turn a stinky, toxic gas into a clean-burning fuel.

A small subset of people, known as controllers, are able to suppress HIV naturally, without the need for medication. A small percentage of controllers ultimately lose the ability to suppress the virus. Researchers have found that aborted control is lik…

The shea tree is best know as a source for a multimillion-dollar ingredient used in cosmetics, personal care products, pharmaceuticals and chocolate. But for hundreds of thousands of African families living in the ‘shea belt’ it is also a crucial sourc…

A recent study revealed that endovascular repair of complex aortic aneurysms using fenestrated and branched endografts provides a safe and effective alternative to open surgical repair, with the lowest ever reported mortality rate in this patient popul…
