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 / Trees use a 'muscle' to correct their posture—a newly discovered role for tension wood
A research team from INRAE and the University Clermont Auvergne has shown that trees are capable of correcting a curvature they detect in their stems through a specific biological process. In the study, young trees with bent ...
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 / Trapped light generates nanoscale magnetization
Using an engineered metasurface that traps light, Cornell researchers have demonstrated a new way to generate strong static magnetic fields without using external magnets or magnetic materials—an approach that could advance ...
Phys.org / Hidden DNA in medieval gospels reveals history of deadly livestock virus
Some of Europe's most well-known historic manuscripts, including the York Gospels, have proven to be biological time capsules for uncovering the 3,500-year history of the sheeppox virus (SPPV).
Phys.org / Chemists design extra-sticky adhesives that degrade on command
A good adhesive is unequivocally sticky. A great adhesive is sticky until you don't want it to be sticky anymore—a label on cardboard until it's time to recycle it. Medical tape on a cut until the wound heals. A GWAR poster ...
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 / 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 / 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 / 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 / Scientists discover the key ingredients that make birdsong pretty
What makes birdsong beautiful? Answering this question could help us understand how soundscapes make the natural world relaxing for humans, opening the door to improving parks, upgrading the design of stressful places like ...
