What people say they've eaten and what they've actually eaten are often two very different lists of foods. But a new technique using DNA barcoding to identify the plant matter in human feces may get at the truth, improving clinical trials, nutrition studies a…

In a time of income inequality and ruthless politics, people with outsized power or an unrelenting willingness to browbeat others often seem to come out ahead.

A study supported by the French Space Agency describes a "reusability kit" that will make any first stage booster retrievable.

A Cretaceous origin for placental mammals, the group that includes humans, dogs and bats, has been revealed by in-depth analysis of the fossil record, showing they co-existed with dinosaurs for a short time before the dinosaurs went extinct.

Isaac Newton formulated his theory of gravity as an action at a distance: a planet instantly feels the influence of another celestial body, no matter the distance between them. This characteristic motivated Albert Einstein to develop the famous theory of gene…

‘Once-in-a-lifetime discovery’: Scientists find rare palm that flowers and bears fruits underground

A team of international scientists has used NASA’s James Webb Space Telescope to detect a new carbon compound in space for the first time. Known as methyl cation (pronounced cat-eye-on) (CH3+), the molecule is important because it aids the formation

The spacecraft is boosting understanding of the Martian surface and atmosphere.

A newly discovered star just 773 light-years away belongs to one of the rarest categories in the Milky Way. J1912-4410 is a white dwarf pulsar, a type of star

The European Space Agency (ESA) will launch the Euclid spacecraft to explore the dark mysteries of the universe on Saturday, US space agency NASA has said. Liftoff will be from Cape Canaveral Space Force Station in Florida, on a SpaceX Falcon 9 rocket.“The ES…

The annual June Boötid meteor shower will stick around until July 2, but its peak — and the best chance to catch a glimpse — will be tonight. In the Pittsburgh area, the shower will be visible from dusk well into the night. But what is it, an…

Scientists have used a recently developed technique to improve predictions of the timing and intensity of the solar wind’s strikes, which sometimes disrupt te

More carbon is stored in the soil than in all plants, animals and the atmosphere combined, making it among the most critical conservation frontiers as we face the climate crisis. According to a recent study published in the journal Nature, microbes are the ke…

Prof. Okujima, in collaboration with Prof. Kobayashi at Shinshu University, have reported the synthesis, molecular structure, optical properties and electronic structure of unusual phenanthrene-fused porphyrins in Organic Letters.

Astronomers have observed a whole new mechanism by which stars can die — by smashing into each other in the most explosive fashion.

Glorious Galaxies, Amazing Aurorae, and Photogenic Planets: The Royal Museums Greenwich has revealed the shortlisted photos for its 15th annual Astronomy Photographer of the Year competition.

Overview of Microbial EukaryotesLiving organisms are categorized based on various characteristics, and one classification system revolves around their cellular components, structure, and function. Consequently, organisms, including microorganisms, can be clas…

See Saturn like never before.

In one experiment, the Viking landers added water to Martian soil samples. That might have been a very bad idea.

A new space telescope named Euclid, an ESA mission with contributions from NASA, is set to launch in July to explore the unknown cause of cosmic acceleration, known as “dark energy.” By May 2027, NASA’s Nancy Grace Roman Space Telescope will join Euclid to ex…

NASA says researchers will simulate the challenges of a human mission to Mars, including resource limitations and equipment failure.

On each flyby, NASA's Juno spacecraft reveals amazing details of Jupiter's cloudscape.

Earth's axis has shifted thanks to human groundwater pumping

New measurements of how particles flow from collisions of different types of particles at the Relativistic Heavy Ion Collider (RHIC) have provided new insights into the origin of the shape of hot specks of matter generated in these collisions. The results may…
