Phys.org / A 100-solar-mass black hole merger ripples spacetime, and may flash in gamma rays
An international team from China and Italy has reported a possible cosmic encore to the landmark 2017 multi-messenger discovery. In November 2024, the LIGO-Virgo-KAGRA observatories detected gravitational waves from a binary ...
Phys.org / The fish were biting in ancient Alabama: Tooth found embedded in Cretaceous apex predator's neck
The oceans of the Cretaceous of North America teemed with life. Gigantic fish and enormous marine reptiles hunted the Western Interior Sea. A unique new fossil demonstrates rare evidence of direct conflict between these apex ...
Phys.org / 'Life is a miracle,' but learning from disasters isn't: Lessons from Japan's 2011 earthquake and tsunami
In April 2012, a Harley-Davidson motorcycle was found on Graham Island in the Haida Gwaii archipelago off the coast of British Columbia. It belonged to Ikuo Yokoyama, a survivor of the earthquake and tsunami that struck northeastern ...
Phys.org / Study documents record 118-kilometer dispersal by young female fisher in New Hampshire
Researchers at the University of New Hampshire have documented the farthest trek of a young female fisher (Pekania pennanti) moving 118 kilometers (over 73 miles) from Durham to the outskirts of Lincoln, a small town in New ...
Phys.org / Cell death in photoreceptor cells is reversible, study finds
Photoreceptors are specialized cells in the eye that convert light energy into neural signals. Several diseases that cause irreversible vision loss, including age-related macular degeneration, retinitis pigmentosa and retinal ...
Phys.org / Nearby red dwarf star hosts at least four planets—with one in the habitable zone
In 2020, a study confirmed that two planets orbited the nearby red dwarf, GJ 887. Now, astronomers have confirmed the existence of two additional planets orbiting GJ 887 in a new study published in Astronomy and Astrophysics. ...
Medical Xpress / Blood tests for cancer? We're still a way off
A new kind of blood test promises to find cancer early—sometimes even before symptoms appear. The pitch is compelling: a single sample of blood could scan the body for dozens of different cancers at once, catching disease ...
Phys.org / Meet Crocodylus lucivenator, a 12- to 15-foot predator that hunted iconic Lucy's species
More than 3 million years ago, when our ancient ancestors embodied by the iconic Lucy were roaming the African landscape, they would have feared a big, bad crocodile with a prominent lump on its head, patiently lurking in ...
Phys.org / Notions of 'Christendom' often miss the mark: Medieval Europe's ideas about faith and power were not so simple
During the National Prayer Breakfast on Feb. 5, 2026, Paula White-Cain, senior adviser to the White House Office of Faith, introduced President Donald Trump as "the greatest champion of faith that we have ever had in the ...
Medical Xpress / Neurons receive precisely tailored teaching signals as we learn, study suggests
When we learn a new skill, the brain has to decide—cell by cell—what to change. New research from MIT suggests it can do that with surprising precision, sending targeted feedback to individual neurons so each one can ...
Phys.org / Nocturnal ants use lunar compass and sophisticated calculations to travel at night
It's well known that many animals, including migratory birds, butterflies, and even fish, use the sun for navigational purposes. Nocturnal animals are dealt a more difficult hand, however, as the moon's path is far more variable. ...
Phys.org / Hydrogen atmosphere could keep exomoons habitable for billions of years
Liquid water is considered essential for life. Surprisingly, however, stable conditions that are conducive to life could exist far from any sun. A research team from the Excellence Cluster ORIGINS at LMU and the Max Planck ...
