Research shows that spinning quasiparticles, or magnons, light up when paired with a light-emitting quasiparticle, or exciton, with potential quantum information applications.

In a new perspective piece, experts propose updating alcohol container warning labels as a strategy to help consumers make more informed decisions about how much they imbibe.

A team has developed an electro-optic frequency comb that is 100-times more efficient and has more than twice the bandwidth of previous state-of-the-art versions.

Getting an annual flu shot may be associated with a lower risk of stroke, according to a new study.

Neutralizing antibody levels against the original COVID-19 virus and omicron variants in vaccinated adults tend to decline by at least 15% per month after a single booster shot, a new study using serum from human blood samples suggests. Data from two a…

Electrical signals tell the heart to contract, but when the signals form spiral waves, they can lead to dangerous cardiac events like tachycardia and fibrillation. Researchers are bringing a new understanding to these complicated conditions with the fi…

Temperatures above or below a feel-good window of 12-21 degrees Celsius (54-70 °F) are linked to a marked rise in aggressive online behaviour across the USA, a new study finds.

Infections in pregnant women have been linked to an increased risk of neurodevelopmental conditions, such as autism, in the child later in life. But it does not seem to be the infections themselves that cause autism, researchers show in a new study.

A potential new treatment combining natural manuka honey with a widely used drug has been developed by scientists to treat a potentially lethal lung infection and greatly reduce side effects of one of the current drugs used for its treatment.

A new study reveals how mechanical forces and tissue mechanics influence the morphology of the developing brain, and establishes a direct link in neural stem cells between Piezo1, a mechanically-activated ion channel, and intracellular cholesterol leve…

Researchers have conducted a study showing how many more species of bees are needed to maintain crop yields when a longer-term time frame is considered.

Let’s pretend it’s the Late Cretaceous, roughly 66 to 100 million years ago. We’ve got dinosaurs roaming the land and odd-looking early species of birds, although the shark as we know it is already swimming in the prehistoric oceans — which cover 82% …

The brain mechanisms that cause aggressive behavior have been well studied. Far less understood are the processes that tell the body when it’s time to stop fighting. Now, a new study identifies a gene and a group of cells in the brain that play a criti…

COVID-19 transmission can be more accurately modeled by incorporating meteorological factors, with ultraviolet (UV) radiation as the main driver, according to a new study.

A new protein, named MAIA after the Greek goddess of motherhood, could be crucial in helping doctors better understand some aspects of infertility and develop novel treatments. Currently, infertility is unexplained in more than half of people who are u…

Depression, anxiety, worry, perceived stress, and loneliness measured early in the pandemic, before infection with COVID-19, were associated with up to 45% increased risk of developing long COVID. Distress was more strongly associated with developing l…

A dieter wrestling with cravings for fatty foods might be tempted to blame their tongue: the delicious taste of butter or ice cream is hard to resist. But new research investigating the source of our appetites has uncovered an entirely new connection b…

Researchers have identified DNA regions that are associated with physical activity or leisure screen time. The findings confirm that physical activity is beneficial for health and suggest that a more sedentary lifestyle can be explained by how muscles …

A new study debunks the idea that wearing a mask to slow the spread of disease damages most everyday social exchanges.

Elevated levels of per- and polyfluoroalkyl substances (PFAS) were associated with higher total cholesterol and non-HDL cholesterol in GenX Exposure Study participants’ blood. The legacy PFAS chemicals PFOS and PFNA were most strongly associated with e…
