A new study assesses the planetary context in which the detection of methane in an exoplanet’s atmosphere could be considered a compelling sign of life….
Study provides new perspective on Washington state’s Channeled Scablands, carved by the Missoula megafloods at the end of the last ice age. As ice sheets…
Astrophysicists Explain the Origin of Unusually Heavy Neutron Star Binaries Simulations of supernova explosions of massive stars paired with neutron stars can explain puzzling results…
The reconstituted biological clock maintains daily cycles for days on end, allowing researchers to study the interactions of its component parts. Daily cycles in virtually…
Researchers can now hold stellar nurseries in their hands thanks to 3D printing, revealing features often obscured in traditional renderings and animations. Astronomers can’t touch…
The Ophiuchus star-forming complex offers an analog for the formation of the solar system, including the sources of elements found in primitive meteorites. A region…
A long-term study in California’s Elkhorn Slough revealed the impact of superabundant crabs on salt marsh vegetation and the vulnerability of tidal creek banks to…
New findings suggest that abnormal ocean currents cause the occasional appearance of pelagic red crabs outside their native range. For decades, people have wondered why…
Over the past 1.2 million years, marine life was repeatedly extinguished in low-oxygen ‘dead zones’ in the North Pacific Ocean during warm interglacial climates. An…
Free of toxic and hallucinogenic side effects, ibogaine-inspired tabernanthalog shows promise as a potential treatment for the detrimental effects of stress on the brain. A…
The gases released from meteorite samples heated in a high-temperature furnace can tell scientists about the initial composition of the atmospheres of rocky exoplanets. In…
New findings show connections between the ancient horse populations in North America, where horses evolved, and Eurasia, where they were domesticated. A new study of…
Oxygen in the atmosphere may not be an entirely reliable ‘biosignature,’ but there are ways to distinguish false positives from signs of life, scientists say….
A new study published in Elementa by researchers at the University of California, Santa Cruz and NOAA examines traditional aspects of seafood sustainability alongside greenhouse gas emissions…
New analysis of strontium isotopes reveals how the global carbon cycle has responded to changes in climate and sea level through geologic time. A new…
UC Santa Cruz researchers published a new study — in collaboration with UC Water and the Sierra Nevada Research Institute at UC Merced — that…
Most of Northern California’s kelp forest ecosystem is gone, replaced by widespread ‘urchin barrens’ that may persist long into the future, according to a new…
Study of flowers with two types of anthers solves mystery that baffled Darwin. Some flowers use a clever strategy to ensure effective pollination by bees,…
