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 / LOFAR reveals spike-like repeating radio burst pairs in the solar corona
The solar atmosphere is a turbulent and magnetized environment, with the release of magnetic energy readily manifesting as emission across the electromagnetic spectrum. Solar radio emission dominates the radio sky, with the ...
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 / 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 / From 718 options to one standout, catalyst screening method reveals durable RuO₂ candidate
Why settle for a trial-and-error approach, reviewing an almost endless number of combinations, when you can systematically narrow the list to something more manageable using established data and knowledge?
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 ...
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 / Bringing ancient light-sensing proteins back to life
Resurrecting dinosaurs using DNA retrieved from a mosquito trapped in amber is a great movie plot, though it's less likely to happen in the real world. However, researchers have been trying to unlock the secrets behind the ...
Phys.org / Fungi help lock carbon into Arctic fjord sediments
Arctic fjords are among the most efficient natural systems for absorbing and storing carbon long term. However, as the Arctic is warming about four times faster than the global average, fjord ecosystems are changing rapidly. ...
Phys.org / New heat-regulating fabric feels fluffy like cotton—but doesn't get wet
Once cotton gets wet, it pulls heat from your body. This is helpful when you're exercising or outside on a hot day, but dangerous in the bitter cold. Now, researchers reporting in ACS Energy Letters have created an ultralight ...
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 / Reversible chirality switching in MoS₂ generates spin currents without magnets
A newly developed method allows researchers to dynamically switch chirality—a particular lack of mirror symmetry—to generate spin currents in semiconductors, researchers from Science Tokyo report. Their approach relies on ...
