Phys.org / A giant star may have destroyed itself in one of the universe's rarest explosions
Astronomers may have discovered one of the clearest examples yet of a rare "pair-instability" supernova. It is a catastrophic explosion thought to completely destroy some of the most massive stars in the universe, leaving ...
Phys.org / Tanzania's iconic heritage sites face damage from state-backed tourism
Assessment of four heritage sites in Tanzania finds that all are under threat from the institutions meant to steward them, prioritizing income from tourism over the sites' preservation and refusing to engage with community ...

Phys.org / First deliberately injured Langobard woman in skeletal record reshapes view of male-only violence
The Langobards are frequently depicted as fierce warrior-like people, with all known archaeological evidence of violence restricted to men. However, nearly 1,400 years ago, a Langobard woman took two severe injuries to the ...
Phys.org / Interstellar object 3I/ATLAS reveals no technosignatures in seven-hour radio scan
Scientists at the SETI Institute recently searched for technological signals from 3I/ATLAS, the third interstellar object observed in our solar system. Using the Allen Telescope Array (ATA) at the Hat Creek Radio Observatory ...
Tech Xplore / From waste wood to load-bearing feature, a simple calculation could change the way we use 'misfit wood'
Urging industry to make better use of wood that is wasted or burned for energy, researchers have released the first structural tests of non-straight, forked, and double-curved roundwood logs used as columns. In his mission ...
Phys.org / Ultrafast laser shrinks to chip scale, potentially lowering costs for diagnostics and atomic clocks
Ultrafast lasers emit pulses lasting only a few hundred femtoseconds (quadrillionths of a second). These flashes of light power applications from precision micromachining to eye surgery to optical frequency combs, the Nobel ...
Phys.org / Plants boost carbon uptake through water efficiency, not heat adaptation, global analysis reveals
An international team of scientists has discovered that plants are not responding to global warming in the way researchers long assumed. Scientists have expected that ecosystems would keep pace with warming by raising the ...
Medical Xpress / How aging reshapes sensorimotor learning: Older adults may lose explicit strategy but gain implicit adaptation
When most humans reach late adulthood, their ability to coordinate movements and maintain balance, broadly referred to as motor control, tends to gradually decline. While these changes in motor control are widely documented, ...
Medical Xpress / Habits form far faster than previously thought, research shows
From responding to the ping of your phone notification to reaching for a snack at the end of the day, many everyday behaviors begin as mindful choices and end up feeling almost automatic. Now a study from Johns Hopkins University, ...
