Phys.org / Discovery of PITTs shows platelets can switch from clotting to driving vessel inflammation
A team from Würzburg has fundamentally changed our understanding of platelet biology. The researchers demonstrate that the surface protein integrin αIIbβ3 is not only a key molecule in blood clotting, but can also act ...
Phys.org / Whales may divide resources to co-exist under pressures from climate change
The North Atlantic Ocean is warming up. Higher temperatures and increased human activity in the region can trigger abrupt changes in marine ecosystems, for example, how species are distributed and what they eat.
Phys.org / Dark energy survey scientists release analysis of all six years of survey data
The Dark Energy Survey Collaboration collected information on hundreds of millions of galaxies across the universe using the U.S. Department of Energy-fabricated Dark Energy Camera, mounted on the U.S. National Science Foundation ...
Phys.org / Amplifying feedbacks could drive Greenland ice sheet to near-complete disappearance
Greenland, which has been prominently in the news in recent days, hosts a vast ice sheet. If it melts, it will become one of the largest contributors to global sea-level rise. Under a high-emissions scenario, the Greenland ...
Phys.org / ATLAS confirms collective nature of quark soup's radial expansion
Scientists analyzing data from heavy ion collisions at the Large Hadron Collider (LHC)—the world's most powerful particle collider, located at CERN, the European Organization for Nuclear Research—have new evidence that ...
Phys.org / Scientists may have discovered a new extinct form of life
Prototaxites are something of a prehistoric mystery. They were the first giant organisms on land, towering over ancient landscapes at heights of up to 8 meters. They had smooth trunk-like pillars and no branches, leaves or ...
Phys.org / Four-eyed Cambrian fish fossils hint at origins of vertebrate pineal complex
New fossil evidence from China suggests that some of our vertebrate ancestors had four eyes. The study, published in Nature, takes a closer look at a structure found in multiple 518 million-year-old fossils, which appears ...
Phys.org / Crouzon syndrome diagnosed in a knight from the Order of Calatrava, killed in battle over 600 years ago
For the ArchaeoSpain research team, it was a day just like any other on their dig at the castle of Zorita de los Canes (Guadalajara). They were working at the Corral de los Condes, where some knights from the Order of Calatrava ...
Phys.org / Astronomers discover dense super-Neptune exoplanet orbiting a sun-like star
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new extrasolar planet orbiting a sun-like star. The newfound alien world, designated TOI-3862 b, turns out to ...
Phys.org / Magnetic 'sweet spots' enable optimal operation of hole spin qubits
Quantum computers, systems that process information leveraging quantum mechanical effects, could reliably tackle various computational problems that cannot be solved by classical computers. These systems process information ...
Phys.org / Hubble uncovers the secret of blue straggler stars that defy aging
Some stars appear to defy time itself. Nestled within ancient star clusters, they shine bluer and brighter than their neighbors, looking far younger than their true age. Known as blue straggler stars, these stellar oddities ...
Phys.org / Ancient giant kangaroos could hop to it when they needed to, hindlimb study suggests
Giant ancestors of modern-day kangaroos—which previous research has estimated could weigh up to 250 kilograms—may have been able to hop in short bursts, according to research published in Scientific Reports.
