Phys.org / What's in an 'O'? Unusual Greek spelling may unlock mystery of ring tied to Pontius Pilate

It's a small, simple ring made of copper alloy and engraved with a handful of Greek letters and the image of a pottery vessel. But its unremarkable appearance belies a remarkable history: The signet was likely connected in ...

Phys.org / PACMAN AI framework for controlling fusion systems safely makes key decisions in milliseconds

Inside some fusion energy systems, particles hotter than the core of the sun can become unruly in a few thousandths of a second, far faster than any human operator can react. A new software framework developed by researchers ...

Phys.org / Mammalian genes can combine to make previously unknown mRNAs and proteins

For decades, scientists have understood that each of the roughly 20,000 genes in the human body carries instructions for a single kind of protein. Now, researchers at Harvard Medical School have discovered that instructions ...

Phys.org / AI-designed proteins enable a new generation of RNA transporters

RNA-based therapeutics use RNA as a blueprint that enables cells to produce specific proteins—including proteins that can precisely modify genes. For this to work, the RNA must reach the inside of the cell intact. Delivery ...

Phys.org / 'Pac-Man' enzyme breaks down bioplastics and penicillin in laboratory tests

In the ocean, plastic waste collects to form large garbage patches that endanger marine life. This is partly because the synthetic plastic polymers used today can only be broken down biologically—that is, by microorganisms—at ...

Phys.org / Copper's oxygen-rich early oxidation layer could inform catalyst design and nuclear waste storage

Copper roofs lose their reddish color over time because a pale green layer of copper oxide forms on their surface, protecting the roof from further corrosion for many years. But what exactly happens during the first steps ...

Phys.org / Ancient fossil from China reveals animal‑microbe partnerships dating back 550 million years

We often think of microbes as organisms that live around us, like the Salmonella bacteria and flu viruses that cause illness. But some of our most intimate relationships are with the microbes living inside us.

Phys.org / Tracing the legal history of the kiss—from property and contracts to consent

Is a kiss just a kiss? Or is it a sign of love, affection, a biological urge, a contract or even an assault? Law, history, evolution and anthropology show that it can be all those things.

Phys.org / Eight-letter DNA alphabet is accurately transcribed by a natural enzyme

All known life on Earth uses the same genetic alphabet, consisting of four letters. Now, researchers at the University of California San Diego have demonstrated that one of biology's most essential enzymes can accurately ...

Phys.org / Fish dads offer new insight into behavioral effects of receiving paternal care

The plot of "Finding Nemo," a film that features an overprotective single father fish taking on dangers at sea to care for his son, may be more reflective of actual fish dad behavior than was previously known. A new study ...

Phys.org / Harnessing gold nanorods and light for targeted cancer therapy

One of the major challenges in the quest to beat cancer is developing treatments that can selectively destroy cancer cells while leaving healthy cells unharmed. With this in mind, researchers at the Indian Institute of Technology ...
