Scientists uncover dominant new microbe group deep in Earth's soil
Apr 10, 2025 (SPX)
"The Critical Zone extends from the tops of trees down through the soil to depths up to 700 feet," Tiedje said. "This zone supports most life on the planet as i...
Strongest biosignature signal yet found on exoplanet
Apr 10, 2025 (SPX)
Using the James Webb Space Telescope (JWST), a research team led by the University of Cambridge identified the spectral presence of dimethyl sulfide (DMS) and/o...
Microscopy study in Earths harsh environments informs alien life search
Apr 10, 2025 (SPX)
Carl Snyder, a physics Ph.D. candidate at Portland State and lead author, emphasized the planetary significance of these analog environments: "These environment...
Saturn's moon Titan could harbor life, but only a tiny amount, study finds
Apr 10, 2025 (SPX)
An international team of researchers co-led by Antonin Affholder at the U of A Department of Ecology and Evolutionary Biology and Peter Higgins at Harvard Unive...
NASA uncovers complex teamwork in magnetic bacteria
Apr 03, 2025 (SPX)
Magnetotactic bacteria are already fascinating for their ability to navigate using microscopic magnetic structures within their cells, aligning with Earth's mag...
Four Small Worlds Discovered Orbiting Nearby Star
Apr 02, 2025 (SPX)
Barnard's Star, just six light-years away, has been a challenging target due to its jittery nature and the difficulty of distinguishing genuine planetary signat...
A new clue to how multicellular life may have evolved
Apr 01, 2025 (SPX)
But what catalyzed the leap from single-celled organisms to complex multicellular life? A new study published in Nature Physics suggests that physical forces, p...
Incredible Journey of Pristine Meteorite Reveals Survival Secrets
Apr 01, 2025 (SPX)
"27 kilos of rocks were recovered, making this the largest fall of its kind since similar meteorites fell near Murchison in Australia in 1969," said meteor astr...
Atmospheres of new planets might have unexpected mixtures of hydrogen and water
Mar 30, 2025 (SPX)
Recent studies show that the most common type of planets in our galaxy, those between the sizes of Earth and Neptune, typically form with a hydrogen atmosphere,...
How calcium may have guided early molecular directionality
Mar 30, 2025 (SPX)
Just as human hands are mirror images of one another, many organic molecules also appear in left- and right-handed forms. However, living systems display a pron...
Were large soda lakes the cradle of life
Mar 26, 2025 (SPX)
This scarcity presents a major question for researchers: how could life have emerged in an environment lacking sufficient phosphorus? Laboratory studies suggest...
Super Earth uncovered by tandem space observations
Mar 26, 2025 (SPX)
To detect exoplanets, astronomers rely mainly on two approaches: the transit method and radial velocity measurements. Transits are detected when a planet dims i...
Fluorescent caves could explain how life persists in extraterrestrial environments
Mar 26, 2025 (SPX)
The researchers will present their results at the spring meeting of the American Chemical Society (ACS). ACS Spring 2025 is being held March 23-27; it features ...
China sends regenerative flatworms to orbit for biological research
Mar 26, 2025 (SPX)
With an evolutionary lineage dating back more than 520 million years, planarians are a staple in laboratory research. Their unique ability to completely regener...
Microbial traces found in desert rocks hint at unknown life form
Mar 19, 2025 (SPX)
"We were surprised because these tubes are clearly not the result of a geological process," said Professor Cees Passchier from Johannes Gutenberg University Mai...
'Dark oxygen': a deep-sea discovery that has split scientists
Mar 17, 2025 (AFP)
Some scientists think so, but others have challenged the claim that so-called "dark oxygen" is being produced in the lightless abyss of the seabed. The discover...
TOI-1453 system hosts contrasting super-Earth and low-mass sub-Neptune
Mar 17, 2025 (SPX)
TOI-1453 resides in a binary star system and is marginally smaller and cooler than the Sun. Around it, two distinct planets have been detected: TOI-1453 b, a ro...
Planetary system discovered around Barnard's Star
Mar 13, 2025 (SPX)
A significant breakthrough has been made by a research team led by Jacob Bean from the University of Chicago. Their specialized instrument, MAROON-X, designed e...
Signs of alien life may be hiding in these gases
Mar 13, 2025 (SPX)
In a new Astrophysical Journal Letters paper, researchers from the University of California, Riverside, describe these gases, which could be detected in the atm...
Small and large planets have significantly different upbringings
Mar 11, 2025 (SPX)
"What we found is that right around the size of Neptune, planets go from being almost always on circular orbits to very often having elliptical orbits," said UC...
