Phys.org / Dual-use research may outgrow national oversight, analysis of 600,000 papers suggests
A new analysis of approximately 600,000 research papers reveals structural limits to single-country security oversight of dual-use research and identifies trade-offs that policymakers face when strengthening such oversight.
Phys.org / First direct view tracks planet-forming disk spinning around AB Aurigae
The rotation of a protoplanetary disk (a disk where planets are being formed) has been observed directly for the very first time by mapping the emissions from the dust grains within it. The disk in question surrounds the ...
Phys.org / Egypt fossils show modern ocean fish rose rapidly after dinosaur extinction
The extinction that ended the Age of Dinosaurs is best known for clearing the way for the Age of Mammals on land. Scientists have long suspected that the same catastrophe also transformed life in the seas, opening ecological ...
Phys.org / Under Notre Dame cathedral, a 'dig of the century' unearths 1,700 years of history
Wilting in the summer sun, a line of tourists waits to climb Notre Dame cathedral and meet its gargoyles.
Phys.org / Biomaterial made from jackfruit latex is a promising treatment for periodontitis
Researchers from the Faculty of Medical and Health Sciences (FCMS) at the Pontifical Catholic University of São Paulo (PUC-SP) in Sorocaba, in the interior of the state of São Paulo, Brazil, have developed a biomaterial containing ...
Phys.org / Lab evolution recreates COVID's path to omicron in months, reveals key conditions
A key step in the origin of many pandemics occurs when an animal-borne virus infects humans and then evolves to spread more efficiently from person to person. That is why scientists and physicians keep a close watch on viruses ...
Medical Xpress / After early pregnancy loss, 'what if' thinking affects 72% within first week
When a person goes through a traumatic experience, they often find themselves thinking that what happened could have been different or even avoided. This process, known as counterfactual thinking, is an automatic psychological ...
Phys.org / Half-ton early bovines roamed 4-million-year-old grasslands in Europe
The first large-sized bovines grew to up to half a ton 4 million years ago in the European Early Pliocene, an early step toward our modern diversity of large-bodied buffalo and cattle, according to a study published June ...
Phys.org / A new origin story for multicellular life points to physics, not genes alone
How did life make the leap from single cells to coordinated, multicellular organisms? And how do genetically identical cells still perform a version of that feat every time an embryo begins to take shape?
Medical Xpress / Long-hidden 'junk DNA' regions may help explain cancer-linked genome instability
Many repetitive regions of the genome have been considered "junk DNA" because the available technologies did not allow them to be studied at sufficient resolution. This is the case for the SST1/NBL2 macrosatellites, considered ...
Phys.org / Pulsar wind nebula inside supernova remnant explored with Chandra
Astronomers from the George Washington University (GWU) in Washington, DC, and elsewhere have employed NASA's Chandra X-ray spacecraft to observe a pulsar wind nebula inside a supernova remnant known as CTA 1. Results of ...
Phys.org / Common plastics soak up ballistic impacts thanks to a cross-linking molecule
With help from a novel cross-linking molecule, MIT chemists have shown they can substantially improve the ballistic impact resistance of common polymers, including polystyrene and a type of rubber used to make shoe soles.
