Phys.org / Supernova origins explored through primordial black holes
Dr. Shing-Chi Leung, assistant professor of physics at SUNY Polytechnic Institute, has published the article "Primordial Black Hole Triggered Type Ia Supernovae II: Comparison with Supernova Remnants and Galactic Chemical ...
Phys.org / Atlantic and Pacific may follow different rules on long-term warming, analysis shows
Florida State University researchers have identified key differences in the root causes of long-term sea-surface temperature changes across the Atlantic and Pacific oceans, a finding that could help guide future research ...
Phys.org / Dozens of active dust devils caught swirling across Mars canyon system
The European Space Agency's Mars Express has captured part of Mars's Mamers Valles, a fascinating valley system speckled with brief, tornado-like whirlwinds known as dust devils.
Phys.org / A 19-year 'goldmine' of mountain cloud and rainwater samples provides fresh insights about air pollution
Rainfall history is just as critical to predicting air pollution as where the air came from, a team led by University of Michigan Engineering researchers, in collaboration with scientists at the Appalachian Mountain Club ...
Phys.org / Mars mission simulations reveal key to teamwork under pressure
Whether it's to the moon or Mars, a NASA mission requires some essential preparations: designing and developing the spacecraft, astronaut training and safety checks, clear goals, and strategies and procedures for maintaining ...
Phys.org / Hidden mitochondrial genes emerge as mealybugs encode two genes on one DNA stretch
What if a single sentence could carry two completely different meanings, one when read forward and another when read backward? In a new study, researchers at Arizona State University have discovered a biological version of ...
Phys.org / How evolution can make cells smaller without slowing down their growth
A new study led by Marco Fumasoni, principal investigator at Fundação GIMM, shows that evolution can substantially reduce cell size without significantly compromising cells' ability to grow. The work, carried out in yeast ...
Phys.org / Thawing permafrost may trigger overlooked carbon sink in rivers
A new study published in Nature shows that rock weathering increasingly counteracts river CO2 emissions as permafrost degrades. The study was carried out by a collaborative team of researchers from Umeå University in Sweden ...
Phys.org / Oddball exoplanet challenges what it means to be a hot Jupiter
New research led by a scientist at IPAC—a science and data center for astrophysics and planetary science at Caltech—studying the hot Jupiter CoRoT-2 b has settled on one of the three leading hypotheses explaining why its ...
Dialog / 'Contaminated' cultures: Can conservation protect nature while excluding Indigenous peoples?
At an international heritage symposium in Japan, I heard a word that stayed with me: "contaminated." The discussion concerned whether Indigenous peoples needed to be named explicitly in a new World Heritage framework. One ...
Phys.org / Tracing a neutrino ghost to a distant 'shadow blaster' galaxy
Neutrinos are one of the fundamental particles of the universe. They live a ghostly existence with no electric charge, very little mass and extremely few interactions with matter. They are also the most abundant particles ...
Phys.org / Bees avoid too much of a good thing by balancing nutrients in pollen, study reveals
New Oxford University-led research reveals that bees can regulate their feeding to avoid overconsuming certain essential nutrients, and that honey bees make a specialist "baby food" that gives their larvae a better-balanced ...
