New research that tested possible triggers of a common heart condition, including caffeine, sleep deprivation and sleeping on the left side, found that only alcohol use was consistently associated with more episodes of the heart arrhythmia.

Retrofitting existing masonry cavity walled buildings with a green or living wall could be a game-changer in helping countries achieve net-zero commitments.

Just three minutes of exposure to deep red light once a week, when delivered in the morning, can significantly improve declining eyesight, finds a pioneering new study.

Researchers have discovered a giant thermoelectric effect in an antiferromagnet. The study shows, surprisingly, that antiferromagnets can have the same value of the anomalous Nernst effect as conventional ferromagnets, but without any stray magnetic fi…

If an automobile is moving at a steady speed over a hill in the shape of a vertical circular arc, what is the maximum speed it can attain without losing contact with the road at the crest of the hill? New research demonstrates that, despite numerous te…

Artificial intelligence-based technique reveals previously unknown cell components that may provide new clues to human development and disease.

Researchers have developed highly efficient, on-chip frequency shifters that can convert light in the gigahertz frequency range. The frequency shifters are easily controlled, using continuous and single-tone microwaves.

Physicists have created a new ultra-thin two-layer material with quantum properties that normally require rare earth compounds. This material, which is relatively easy to make and does not contain rare earth metals, could provide a new platform for qua…

An international research team that synthesized a new ultrahard form of carbon glass with a wealth of potential practical applications for devices and electronics. It is the hardest known glass with the highest thermal conductivity among all glass mate…

Mounded, luminous clouds of gas and dust glow in this Hubble image of a Herbig-Haro object known as HH 45. Herbig-Haro objects are a rarely seen type of nebula that occurs when hot gas ejected by a newborn star collides with the gas and dust around it …

A new statistical analysis supports beliefs that COVID-19 became more lethal in the U.K. in late 2020, while also suggesting that multiple factors — not just the alpha variant of the virus that causes COVID-19 — were to blame.

The Arctic Ocean has been getting warmer since the beginning of the 20th century — decades earlier than records suggest — due to warmer water flowing into the delicate polar ecosystem from the Atlantic Ocean.

Referred to as ‘China’s Venice of the Stone Age’, the Liangzhu excavation site in eastern China is considered one of the most significant testimonies of early Chinese advanced civilization. More than 5000 years ago, the city already had an elaborate wa…

New research shows how switching from a restricted diet to eating as much as you like could be beneficial for reproduction in later life. Researchers studied the eating and mating habits of the small fruit fly Drosophila melanogaster. They found that t…
