A new study has found that chemicals that accumulate in the vagina, potentially originating from personal care products, may contribute to preterm birth.

Using artificial intelligence, engineers have simplified and reinforced models that accurately calculate the fine particulate matter (PM2.5) — the soot, dust and exhaust emitted by trucks and cars that get into human lungs — contained in urban air po…

Disturbances to Earth’s magnetic field can lead birds astray — a phenomenon scientists call ‘vagrancy’ — even in perfect weather, and especially during fall migration. While other factors such as weather likely play bigger roles in causing vagrancy, …

Understanding how dust grains form in interstellar gas could offer significant insights to astronomers and help materials scientists develop useful nanoparticles.

Chemists have found a simple way to produce previously inaccessible chiral Z-alkenes, molecules that offer a significant synthetic short-cut for the production of bioactive molecules. Instead of eight to ten synthetic steps to produce these molecules, …

Scientists have used paleogenomics to trace 10,000 years of human immune system evolution. They analyzed the genomes of more than 2,800 individuals who lived in Europe over the past ten millennia. They were able to date the increase in frequency of mos…

This laboratory protocol gives researchers a road map to understand the complex traffic system between the gut and the brain and its effects both in health and disease.’

The conversion of solar energy into hydrogen energy represents a promising and green technique for addressing the energy shortage and reducing fossil fuel emissions. A research team recently developed a lead-free perovskite photocatalyst that delivers …

Madagascar is home to a unique biodiversity with a large number of endemic species, among those many lemur species, including the mouse lemurs. This diversity is also found in their retroviruses. Biologists analyzed the mouse lemur genome and identifie…

Earth’s average surface temperature in 2022 tied with 2015 as the fifth warmest on record, according to an analysis by NASA. Continuing the planet’s long-term warming trend, global temperatures in 2022 were 1.6 degrees Fahrenheit (0.89 degrees Celsius)…

Scientists have decoded the physical process that takes place in the mouth when a piece of chocolate is eaten, as it changes from a solid into a smooth emulsion that many people find totally irresistible. By analyzing each of the steps, the interdiscip…

A team has studied the relation between galaxy size and luminosity of some of the earliest galaxies in the universe taken by the James Webb Space Telescope, less than a billion years after the Big Bang.

A new study of domestic and hospital drinking water systems found Legionella in 41% of samples — with researchers making a key connection between the pathogen’s co-existence with a ‘host’ microorganism in all samples tested. The study found Legionella…

Magnesium hydride has long been touted for its potential to store large amounts of hydrogen, something essential if hydrogen is to play a role in powering a sustainable future. Yet, sluggish dehydrogenation kinetics and the high temperature required to…

Until now, microscopic robotic systems have had to make do without arms. Now researchers have developed an ultrasonically actuated glass needle that can be attached to a robotic arm. This lets them pump and mix minuscule amounts of liquid and trap part…

Birds fly more efficiently by folding their wings during the upstroke, according to a recent study. The results could mean that wing-folding is the next step in increasing the propulsive and aerodynamic efficiency of flapping drones.
