Dialog / Miniature satellite tags reveal diving behavior of juvenile sea turtles
Until recently, researchers were unable to conduct satellite-tracking studies on juvenile turtles because of their small body sizes and immediate dispersal into the ocean, leaving this period of their lives enigmatic and ...
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 / 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 / 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 / Australia's under-16 social media ban shows little early effect on teen use: Research
Australia's social media ban for under-16s has had little impact on teenagers' scrolling habits, researchers said Thursday in one of the first evaluations of the world-leading measures.
Phys.org / Shorter front-leg strides can be an early warning sign of dementia in senior dogs
Scientists have shown that the stride length of the front legs (but not the hind legs) of senior and geriatric dogs decreases as their cognitive performance worsens. In contrast, chronological age itself was a poor predictor ...
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 / 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 ...
Phys.org / Laser experiments push helium to record shock pressures
Deep inside gas giants like Jupiter and Saturn, hydrogen and helium coexist under pressures millions of times greater than Earth's atmosphere. Under those conditions, helium may separate from hydrogen and influence a planet's ...
Phys.org / Language-based screeners may miss kids who struggle to read due to visual-processing issues
Reading difficulties, like dyslexia, are common and often affect achievement and outcomes during school and later in life. A new study, published in Current Biology, reports that current methods used to test for reading disabilities ...
Phys.org / How longer exciton lifetimes could ease efficiency trade-off in organic solar cells
Although the efficiency of organic solar cells has now risen to more than 20%, there are physical limits that make it difficult to further increase their performance. A research team from Linköping University in Sweden, the ...
