Phys.org / Skin and color pattern of 125-million-year-old crocodile revealed by extraordinary fossil from the Pyrenees
A new study published in Zoological Journal of the Linnean Society describes, for the first time in detail, the soft tissues preserved in Montsecosuchus depereti, a Lower Cretaceous crocodylomorph from the Pedrera de Meià ...
Phys.org / Drug-free nanoparticles stop tumor growth by transmitting biological messages to immune cells
A research team from the Technion's Wolfson Faculty of Chemical Engineering has developed an original technology for treating cancer using nanoparticles that carry no drugs at all and has demonstrated its effectiveness against ...
Phys.org / Mountain lions have major ecological impact even in small preserves
Big cats have a big impact. A long-term study showed that when mountain lions began regular visits to a small suburban preserve about 45 miles (72 kilometers) south of San Francisco, they changed the behavior of many other ...
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 / 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 / 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 / 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 / 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 / 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 / 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 / How bacteria exploit human cell metabolism to sharpen infections and potentially evade treatment
A research team at the University of Greifswald's Research Training Group RTG-PRO "Proteases in pathogen and host: importance in infection and inflammation" has discovered a new mechanism by which bacterial pathogens adjust ...
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.
