Phys.org / Growing up gets less scary with time, research finds
As young adults, many millennials feared growing up more than past generations. But they've come around to it as they age, research published in the journal Developmental Psychology has found.
Phys.org / This single well-known and widespread butterfly is actually three species in disguise
The tropical rainforests of Central and South America are among the most biodiverse places on Earth. Costa Rica alone is home to half a million species, five times more than exist in the entire country of Canada, despite ...
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 ...
Phys.org / Self-propelled actin filaments may explain how cells change shape spontaneously
Cells can spontaneously change shape even without external signals, but the underlying mechanisms behind this form of self-organization have remained unclear. Now, researchers from Japan have discovered self-propelled treadmilling ...
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 ...
Phys.org / Students' climate model of deadly July 4 Texas flooding suggests sea surface temperatures actually reduced rainfall
Last fall, the 12 students in the Jackson School of Geosciences' GEO 347G "Climate System Modeling" class set out to understand something that hit close to home: What were the climatological factors that made the July 4, ...
Phys.org / New electrocatalyst helps turn polluted water into fertilizer and polymers
A new electrochemical system simultaneously converts plant-derived materials and nitrate pollutants into valuable industrial chemicals. Developed by Tohoku University researchers, the system provides a more sustainable way ...
Phys.org / Organic carbon detected in Bright Angel rock formation on Mars
In September 2025, NASA announced that its Perseverance rover had discovered a potential biosignature, which is a substance or structure that might have a biological origin. A new paper, published in Science Advances, unambiguously ...
Phys.org / 'Super-puff' planets less dense than cotton candy discovered by international team
An international collaboration has discovered two of the lowest-density giant planets ever detected: rare "super-puff" planets with densities lower than candy floss. The study—led by the University of Oxford, in collaboration ...
Phys.org / Binary black hole signal probes event horizon region for first time
If, in space, no one can hear you scream, it seems that you can actually hear the sound of a crash when two black holes collide. Using the loudest gravitational wave ever heard, two Australian scientists and colleagues have ...
Phys.org / Ancient proteins hint at all-female Homo naledi burial site in Rising Star cave system
Scientists have extracted and analyzed the first-ever ancient proteins from the fossils of Homo naledi, revealing a potential all-female burial site. The study, published in the journal Cell, raises the possibility that South ...
