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 / '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 / 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 / Cellular maintenance crew may miss as much as half of certain misfolded proteins
As proteins are made in a cell, they are folded into the 3D structure that allows them to work, but sometimes this process can go wrong. When it does, the misfolded proteins lose some or all of their function and usually ...
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 / New nanostructure makes non-linear light conversion 72,000 times more efficient
Researchers from Graz University of Technology (TU Graz), Harvard and the University of Texas at Austin (UT Austin) have developed an innovative method for coupling light non-linearly. This opens up new possibilities for ...
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 / 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 / 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 / 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 / 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 ...
