Phys.org / Mysterious transient objects in sky linked to nuclear testing and unidentified anomalous phenomena
A new study analyzing historical photographs taken by the Palomar Observatory between 1949 and 1957 has detected several mysterious bright spots in the sky. These transient objects, captured on film before the first satellites ...
Phys.org / Dwarf galaxies tip the scales in favor of dark matter over modified gravity
An international team of researchers led by the Leibniz Institute for Astrophysics Potsdam (AIP) has shed light on a decades-long debate about why galaxies spin faster than expected—and whether this behavior is caused by ...
Phys.org / Weathering of the Southern Andes plays a critical role in balancing CO₂ emissions
The towering peaks of the Southern Andes are not just shaping the skyline of South America—they are also quietly influencing Earth's atmosphere.
Phys.org / MeerKAT detects 30 new radio transient pulsars
Using the MeerKAT telescope, an international team of astronomers have detected 30 new radio transient pulsars as part of the Meer(more) TRAnsients and Pulsars (MeerTRAP) project. The discovery was reported in a paper published ...
Phys.org / Why did ancient people build Poverty Point?
Some 3,500 years ago, hunter-gatherers began building massive earthwork mounds along the Mississippi River at Poverty Point, a UNESCO World Heritage Site in northeast Louisiana. "Conservatively, they moved 140,000 dump truck ...
Phys.org / More friends, more division: Study finds growing social circles may fuel polarization
Between 2008 and 2010, polarization in society increased dramatically alongside a significant shift in social behavior: the number of close social contacts rose from an average of two to four or five people. The connection ...
Phys.org / Earliest long-snouted fossil crocodile from Egypt reveals the African origins of seagoing crocs
In the Egyptian Western Desert, where red sandstones and green shales rise above the arid plains of Kharga Oasis, paleontologists have uncovered a fossil that fundamentally reshapes our understanding of crocodile evolution.
Phys.org / Why honey bees overthrow their queen
It sounds like the plot of a medieval historical drama: A once-powerful monarch, weakened by illness, is overthrown by her previously loyal subjects. But in honey bee colonies, such high-stakes coups aren't just fantasy—they're ...
Phys.org / Chemists discover antibiotic for drug-resistant bacteria 'hiding in plain sight'
Chemists from the University of Warwick and Monash University have discovered a promising new antibiotic that shows activity against drug-resistant bacterial pathogens, including MRSA and VRE
Phys.org / Six new bat species discovered in protected forests of the Philippines
Just in time for Halloween, six new bat species have been discovered by researchers from the Royal Ontario Museum (ROM), Field Museum in Chicago, and Lawrence University in Wisconsin. This nocturnal—and slightly spooky—group ...
Phys.org / Electric signals reveal magnetic spin waves, hinting at faster computing
Today's computers store information in magnetic hard drives, keeping files safe even when the device is powered off. But to run programs and process information, computers rely on electricity. Each calculation requires a ...
Phys.org / Memristors achieve stable resistance values tied to fundamental constants of nature
Researchers at Forschungszentrum Jülich, together with international collaborators, have demonstrated for the first time that memristors—novel nanoscale switching devices—can provide stable resistance values directly ...
