Phys.org / Fossils upend catastrophist narrative that flowering plants flourished only after dinosaur extinction
A unique cache of plant fossils from volcanic deposits in New Mexico contradicts the common narrative that flowering plants were minor players in Earth's forests until dinosaurs disappeared 66 million years ago.
Phys.org / Seven exotic quantum phases predicted in ultracold magnetic atoms, including topological superconductivity
Strongly interacting quantum particles are key to some of the most fascinating phenomena in modern physics—from magnetism and superconductivity to topological states. Yet the complexity of such systems makes many of their ...
Phys.org / Check politics at the door? Not at many workplaces, researcher says
When people think of workplace segregation, they usually think of race or gender. Yet Americans are also sorted at work by something employers rarely measure: how they vote.
Phys.org / Economic and environmental benefits of regenerative agriculture vary widely across farms and regions
Regenerative agriculture can deliver both economic and environmental benefits for European farmers, Wageningen University & Research (WUR) concludes in the research project Regenomics. Whether these benefits are actually ...
Phys.org / Defect detection automated in diamond, other advanced semiconductors
Materials scientists at Rice University have developed a new workflow methodology for measuring microscopic defects in diamond and other advanced semiconductor materials. By making it easier to spot flaws that can undermine ...
Medical Xpress / Opposing protein pathways steer skin stem cells toward renewal or repair
Two proteins with opposing functions orchestrate the development and maintenance of healthy skin, Stanford Medicine researchers have found. Modulating their activity with topical drugs could reduce inflammation, aid wound ...
Medical Xpress / Concussion symptom history linked to increased odds of tinnitus
Greater concussion symptom history is associated with increased odds of tinnitus, and associations with cognition, depression, and anxiety are larger among those with tinnitus, according to a study published online June 19 ...
Tech Xplore / Western Australia police are scanning faces in public—and the law is not ready for the consequences
In a first for Australian law enforcement, police in Western Australia have deployed live facial recognition technology in marked vans at locations around Perth.
Phys.org / What really controls water chemistry in nanoscale spaces
Water is the most studied molecule on Earth, yet a surprisingly basic question has gone unanswered for decades: When water is squeezed into gaps just a few molecules wide—as happens inside nanoscale pores, membranes and biological ...
Phys.org / The 2 earthquakes that struck Venezuela are known as a 'doublet.' Here's how they happen
The two powerful earthquakes that struck Venezuela's northern coast, killing more than 180 people, were an event known as a "doublet."
Phys.org / Antibiotics trigger bacterial teamwork, boosting survival through shared proteins
When bacteria are under antibiotic attack, it is not "every man for himself." Researchers at Baylor College of Medicine and colleagues from collaborating institutions have discovered that bacterial populations work as a team ...
Tech Xplore / IBM unveils 0.7-nanometer chip tech promising 50% higher performance and up to 70% better energy efficiency
IBM unveiled new semiconductor technology Thursday that the company says could deliver computer chips with 50% better performance while dramatically lowering power consumption.
