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 ...
Medical Xpress / Psychiatrists hope chat logs can reveal the secrets of AI psychosis
"You're not crazy," the chatbot reassured the young woman. "You're at the edge of something."
Phys.org / A new study of lunar rocks suggests Earth's water might not have come from meteorites
For a long time, scientists assumed that Earth's water was delivered by asteroids and comets billions of years ago. This coincided with the Late Heavy Bombardment (ca. 4.1 to 3.8 billion years ago), a period when planets ...
Dialog / Using amino acids as fuels to make conductive graphene
Graphene has drawn attention as a scientific curiosity owing to its record conductivities, strength and thermal properties. But now, it's starting to make its way into a number of real-world applications, from batteries to ...
Phys.org / Complex building blocks of life form spontaneously in space, research reveals
Challenging long-held assumptions, Aarhus University researchers have demonstrated that the protein building blocks essential for life as we know it can form readily in space. This discovery, appearing in Nature Astronomy, ...
Medical Xpress / Learning from the Global South: How do people cope with heat?
Climate change presents tremendous challenges, especially for people in the Global South. Two international studies led by Charité—Universitätsmedizin Berlin have investigated how the population in sub-Saharan Africa ...
Phys.org / Physicists uncover hidden magnetic order in the mysterious pseudogap phase
Physicists have uncovered a link between magnetism and a mysterious phase of matter called the pseudogap, which appears in certain quantum materials just above the temperature at which they become superconducting. The findings ...
Phys.org / Wildfires trigger massive soil loss for decades, new global map shows
Wildfires are devastating events that destroy forests, burn homes and force people to leave their communities. They also have a profound impact on local ecosystems. But there is another problem that has been largely overlooked ...
Phys.org / What deep sea mud is revealing about giant earthquakes along the Pacific Coast
Marine turbidites are layers of mud and sand deposited on the deep ocean floor by massive underwater landslides and are often used as a historical record for reconstructing earthquake histories.
Phys.org / Banal but brutal: Career anxiety as a driving force behind authoritarianism
Career pressure—not ideology—causes military officers to protect or overthrow dictators. New research from the Department of Political Science shows that ambition and anxiety can transform "ordinary men" into the regime's ...
Phys.org / Fewer disinfection by-products present in bottled water compared to tap, study finds
Department of Chemistry and Biochemistry researchers at the University of South Carolina measured disinfection by-products in bottled water, with total disinfection by-products ranging from 0.01–22.4 µg/L and compared ...
Phys.org / Marine wildlife rarely interact with tidal turbines—and usually avoid collisions when they do, observations show
Tidal turbines harbor the potential to provide a natural, inexhaustible source of power, but have faced some regulatory hurdles and scientific uncertainty about risks to marine life.
