Phys.org / Dark energy and quantum gravity may be deeply intertwined
For close to a century, physicists have pursued a way to unite gravity with quantum mechanics. Known as quantum gravity, this goal has remained frustratingly out of reach so far. Similarly elusive is the force of dark energy, ...
Phys.org / Archaeologists investigate a feared young woman's 17th century vampiric grave in Poland
In 2022, excavations at a cemetery in Pień, Poland, led by researchers from the Institute of Archaeology at Nicolaus Copernicus University, led to a mysterious discovery. In what they call Grave 75, they uncovered the 400-year-old ...
Tech Xplore / Meta and U.S. states discuss settlement in landmark social media trial: Report
Social media giant Meta has been in discussions with multiple U.S. states to settle a major child privacy and consumer protection case out of court, Bloomberg News reported Tuesday.
Medical Xpress / Clear Eyes eye drops recalled nationwide over sterility concerns
Nearly 40,000 bottles of a widely sold eye drop are being pulled from shelves nationwide because the maker cannot guarantee the product is sterile.
Phys.org / Setting limits on phase transitions in the dark energy era
The universe is known to be expanding at an accelerating rate. Physicists typically attribute this acceleration to dark energy, a mysterious component of the universe that exerts negative pressure, causing space to expand ...
Phys.org / New solar system models show Earth is no fluke
Over the past three decades, computer models of planetary system formation have gone from fairly crude representations to sophisticated simulations using thousands of different starting points.
Medical Xpress / Heart capillaries may build natural bypasses for blood flow after heart attacks
The heart powers a busy highway of arteries and vessels, providing a constant to-and-fro passage for blood. During a heart attack, this passage becomes blocked, usually when a blood clot forms on plaque in a coronary artery ...
Phys.org / LHC collisions reveal oxygen and neon's shifting nuclear geometry
Many people are aware that the Large Hadron Collider (LHC) at CERN smashes tiny subatomic particles together at nearly the speed of light to test foundational laws of physics and discover new fundamental particles, but some ...
Phys.org / A little Big Bang: Bowling-pin-shaped nuclei shed new light on the universe's first moments
What happened in the first moments of the universe—before the building blocks of life and the world we know today came into existence? Physicists at the CERN research facility in Switzerland are trying to answer this question ...
Phys.org / Egypt's deserts were once home to a diverse shark community
During the Late Cretaceous period, parts of Egypt were covered in water. A new study, published in the journal Cretaceous Research, describes new evidence that this tropical sea was home to a diverse community of sharks. ...
Phys.org / The hidden physics behind the shape of rose thorns
Roses are known for their thorns, the sharp structures that can sting and prickle the skin. Thorns, botanically known as prickles, are thought to discourage animals from feeding on plants and may also help climbing roses ...
Phys.org / The little red dots of our cosmos might hide something big
Little red dots may reside in small, dense galaxies with total masses equivalent to around 1 billion times that of the sun, according to research published in Nature Astronomy.
