Phys.org / Huge dinosaur bone may reveal the origins of T. rex
Tyrannosaurus rex is one of the most recognizable names of the dinosaur world, a hulking and terrifying meat-eating behemoth. While fossil remains have been extensively studied, not much is known about its family history ...
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 / 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 / Bright pink insect stands out to blend in, scientists say
A tropical insect has been found to change color from vivid hot pink to green within a fortnight, which scientists believe may mimic the young leaves of rainforest plants. The findings, published this week in the journal ...
Phys.org / Decades-old problem in classical geometry solved: First compact pair of bonnets found
For over 150 years, a rule of thumb dating back to the French mathematician Pierre Ossian Bonnet has been accepted in surface theory: If the metric and mean curvature of a compact surface are known at every point, then the ...
Phys.org / Bacterial strain breaks decades-old bottleneck in chemotherapy drug manufacturing
An international team of researchers has achieved a breakthrough in the production of doxorubicin, a vital chemotherapy agent. The study identifies and resolves molecular "bottlenecks" that have limited the natural production ...
Phys.org / Physicists observe rare nuclear isomer in ytterbium-150 for first time
Nuclear isomers are crucial probes for studying the structure of nuclei. Unlike chemical isomers—which have the same chemical formula but different arrangements of atoms—nuclear isomers are nuclei that exist in a long-lived ...
Phys.org / Improperly disposed wet wipes could shed microplastics in rivers
Wet wipes conveniently clean and sanitize soiled surfaces and skin. Because some labels do not clearly indicate how consumers should dispose of them, these small cloths are often flushed down the toilet and released by sewage ...
Phys.org / Researchers realize room-temperature two-dimensional multiferroic metal
Multiferroic metals are materials that exhibit both electric polarization and magnetic order in the same crystal—a state known as multiferroicity. Because these properties coexist, they can interact through magnetoelectric ...
Phys.org / In a South Carolina swamp, researchers uncover secrets of firefly synchrony
In the middle of the old-growth forests of Congaree National Park in South Carolina, fireflies put on an otherworldly display every May. Thousands of male insects belonging to the species Photuris frontalis flash together ...
Phys.org / Ultrasound-based approach to delivering potent drugs into cancer cells shows promise in benchtop experiments
Engineers at Duke University have demonstrated a technique that uses microbubbles and ultrasound to help relatively large cancer drugs enter tumor cells and cause them to self-destruct. Dubbed "Sonoporation-assisted Precise ...
Phys.org / Can plants count? Study suggests they can track the number of events they experience
It's long been assumed that for an organism to learn, remember or draw conclusions, it needs a brain. But mounting evidence, including a recent Cognitive Science study, challenges that assumption, suggesting that neurons ...
