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 / Mineral garnet discovered in Mars meteorite may reveal how the red planet evolved billions of years ago
An international team of scientists has identified a completely new type of rock from the red planet and, for the first time, discovered the mineral garnet in a Martian sample. The breakthrough offers a rare glimpse into ...
Phys.org / Volcanic shifts suggest Andes mountain growth comes in powerful bursts rather than a slow and steady rise
Scientists have discovered that the southern Andes Mountains don't rise slowly and steadily as previously thought. Instead, the range builds itself in short, powerful "pulses" every few million years.
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 / Radar echoes from Europa reveal secrets beneath the ice
A team of scientists has used NASA's Goldstone Solar System Radar and the U.S. National Science Foundation Green Bank Telescope (NSF GBT) to carry out the most extensive radar study to date of Europa, the ocean world orbiting ...
Phys.org / Dark matter cannot be ruled out as cause of gamma ray glow at the Milky Way's center, machine learning shows
An international research collaboration between the University of Vienna and Lawrence Berkeley National Laboratory in the United States has used machine learning to re-examine one of the most debated signals in astrophysics. ...
Phys.org / Plants maintain photosynthesis in hotter, drier climates by coordinating biochemical processes to stabilize CO₂ levels
Researchers at The Australian National University (ANU) have uncovered a mechanism that helps plants continue photosynthesizing under extreme heat and dry air conditions—a finding that could improve how scientists predict ...
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 ...
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 / Frozen Greenland middens preserve 4,500 years of farms, seal hunts and toilets
Greenland has a long and checkered history of human settlement: several Paleo-Inuit cultures since approximately 2,500 BCE, descendants of Vikings between the 10th and 15th centuries, and early modern Danes since 1721. All ...
Phys.org / Dark biodiversity helps solve Darwin's 160-year-old puzzle
An international research team, which included University of Tartu visiting doctoral student Wen-Gang Zhang and Professor of Botany Meelis Pärtel, has found a new solution to one of ecology's long-standing controversies—Darwin's ...
Phys.org / Could Earth have sent life to Jupiter's moon Europa?
Could Earth have seeded Jupiter's moon Europa with bacterial life, where it could have taken hold in Europa's ocean and perhaps evolved into something more? That's the hypothesis of a new paper in the International Journal ...
