Phys.org / Livestock played a role in prehistoric plague infections, genomic study finds
Around 5,000 years ago, a mysterious form of plague spread throughout Eurasia, only to disappear 2,000 years later. Known only from ancient DNA, this enigmatic "LNBA plague" lineage has left scientists puzzled about its likely ...

Phys.org / Common food bacteria could help make vitamins cheaper and greener
A new study reveals how Lactococcus lactis (L. lactis), a common food bacterium, regulates the production of a key precursor in vitamin K₂ (menaquinone) biosynthesis. The bacteria produce enough of this precursor to support ...

Dialog / Rethinking imperfections: How defects are powering brighter perovskite emissions
In materials science, defects are usually seen as problems, unwanted microscopic features that degrade performance, reduce efficiency or shorten the lifespan of devices. But a recent breakthrough published in Advanced Materials ...

Phys.org / Shifting foundations of the Antarctic food web could ripple through the entire ecosystem
Researchers from Denmark, New Zealand, Australia, Spain and the U.S. have reconstructed the composition of phytoplankton communities around Antarctica over nearly three decades, the most comprehensive study of its kind to ...

Phys.org / 56 million years ago, Earth underwent rapid global warming—here's what it did to pollinators
Pollinators play a vital role in fertilizing flowers, which grow into seeds and fruits and underpin our agriculture. But climate change can cause a mismatch between plants and their pollinators, affecting where they live ...

Phys.org / Two solutions unlock safer RNA therapies for inflammatory diseases
Lipid nanoparticles (LNPs) are tiny fat bubbles that are used to deliver medicines, genes, and RNA into cells. However, in some cases LNPs can cause harmful inflammation as a result of the process of RNA delivery.

Phys.org / Previously unknown protein 'folding factories' discovered
In order to fulfill their many functions, proteins must be folded into the correct shape. Researchers at the University of Basel have now discovered tiny "folding factories" in cells that enable efficient and accurate protein ...

Phys.org / Researchers discover all-new antifungal drug candidate in campus greenhouse
A research team at McMaster University has discovered a new drug class that could someday lead to breakthrough treatments for dangerous fungal infections. The new molecules, dubbed coniotins, were isolated from a plant-dwelling ...

Phys.org / Lakes may be carbon sinks, not sources, thanks to overlooked shorelines
Lakes have long been viewed as sources of carbon dioxide emissions, but new research suggests they may actually act as carbon sinks. A study led by Uppsala University reveals that lake shorelines store more carbon than previously ...

Phys.org / Students' image tool offers sharper signs, earlier detection in the lab or from space
A group of UBC Okanagan students has helped create technology that could improve how doctors and scientists detect everything from tumors to wildfires.

Phys.org / Couples who meet online less happy in love, study shows
People who meet their romantic partners online report lower levels of marital satisfaction and experience love less intensely than those who meet in person. That's according to an international team of researchers led by ...

Phys.org / Atomic-level simulations reveal new class of protein misfolding in high definition
New computer simulations that model every atom of a protein as it folds into its final three-dimensional form support the existence of a recently identified type of protein misfolding.
