JWST confirms giant planet atmospheres vary widely
Astronomers have found the atmospheric compositions of giant planets out in the galaxy do not fit our own solar system trend.
Temperature of a rocky exoplanet measured
An international team of researchers has used NASA’s James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The measurement is based on the planet’s thermal emission: heat energy given off in the form of infrared lig…
Bomb-sniffing rodents undergo ‘unusual’ reproductive transformations
Female giant African pouched rats, used for sniffing out landmines and detecting tuberculosis, can undergo astounding reproductive organ transformations, according to a new study.
Human body a breeding ground for antimicrobial resistance genes
The community of microbes living in and on our bodies may be acting as a reservoir for antibiotic resistance, according to new research.
The Greenland Ice Sheet is close to a melting point of no return
A new study using simulations identified two tipping points for the Greenland Ice Sheet: releasing 1000 gigatons of carbon into the atmosphere will cause the southern portion of the ice sheet to melt; about 2500 gigatons of carbon means permanent loss …
Beneficial bacteria in the infant gut uses nitrogen from breast milk to support baby’s health
A nutrition scientist who has spent his career studying breast milk has demonstrated how beneficial microbes in the gut of infants use nitrogen from human milk to support pediatric nutrition and development.
HIV genomes that hide in white blood cells offer new target to eliminate infections
To develop treatments that may one day entirely rid the body of HIV infection, scientists have long sought to identify all of the places that the virus can hide its genetic code. Now, in a study using blood samples from men and women with HIV on long-t…

What do the elements sound like?
In chemistry, we have He, Fe and Ca — but what about do, re and mi? Using a technique called data sonification, a recent college graduate has converted the visible light given off by each of the elements into soundwaves. The notes produced for each el…

Colorful films could help buildings, cars keep their cool
The cold blast of an air conditioner can be a relief as temperatures soar, but ‘A/C’ units require large amounts of energy and can leak greenhouse gases. Today, scientists report an eco-friendly alternative — a plant-based film that cools when exposed…
New ways to measure curls and kinks could make it easier to care for natural hair
Black women and others with curly or kinky hair encounter a confusing array of haircare options. Advice on the best products to use for a certain type of hair is often contradictory, and the results can be highly variable. Now, scientists are bringing …
Two meteorites are providing a detailed look into outer space
If you’ve ever seen a shooting star, you might have seen a meteor on its way to Earth. Those that land here can be used to peek back in time, into the far corners of outer space or at the earliest building blocks of life. Scientists have conducted some…
Human cells help researchers understand squid camouflage
Squids and octopuses are masters of camouflage. But some aspects of how they become reversibly transparent are still ‘unclear,’ because researchers can’t culture cephalopod skin cells in the lab. Now, researchers have replicated the tunable transparenc…
Looking from different perspectives! Proper electronic structure of near-infrared absorbing functional dyes discovered
A research group has discovered that near-infrared absorbing dyes, which had previously been considered to have closed-shell electronic structures, have an intermediate electronic structure, between closed- and open-shell structures. They also found th…
Earth’s first plants likely to have been branched
A new discovery changes ideas about the origin of branching in plants.
Art evokes feelings in the body
A new study reveals that art has a powerful effect on people’s bodies and emotions.
Surprise effect: Methane cools even as it heats
Most climate models do not yet account for a recent discovery: methane traps a great deal of heat in Earth’s atmosphere, but also creates cooling clouds that offset 30% of the heat.
Vehicle exhaust filters do not remove ultrafine pollution
Filters fitted to vehicle exhaust systems to remove particulate matter pollution have limited impact on ultrafine particles, new research shows.
