Phys.org / Grasslands could lose four times more carbon uptake under future drought conditions
The effects of individual climate factors on ecosystems are usually considered in isolation. However, in reality, they occur simultaneously and influence each other. Increasing CO2 concentrations in the atmosphere contribute ...
Medical Xpress / Two studies point to beta cells as active players in type 1 diabetes
Type 1 diabetes is widely understood as an autoimmune disease, with the immune system attacking the insulin-producing beta cells of the pancreas. But two new studies suggest those cells may be more than passive victims. Together, ...
Phys.org / Loss of DNA protector gene exposes vulnerabilities in cancerous cells
Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist Simon Boulton is interested in how cells spot and repair damage to their DNA, and what happens if this ...
Medical Xpress / Brain–computer interface detects hidden awareness in unresponsive patients
A new approach for identifying signs of hidden awareness in people who cannot speak or move after severe brain injury has been demonstrated by researchers at the University of Bath in the U.K.
Medical Xpress / Billions of doses later: Global review confirms mRNA vaccines are safe, effective and full of promise
A sweeping global review led by researchers at the University of British Columbia has found that mRNA vaccines—now administered billions of times worldwide—are safe and highly effective at preventing infectious diseases like ...
Phys.org / Medici brothers' remains reveal Renaissance-era malaria strains, closing the book on a murder mystery
In 1562, Cardinal Giovanni de Medici, a scion of the dynastic family that dominated politics and banking in Tuscany during the Renaissance, died of malaria. Twenty-five years later, his older brother, Grand Duke Francesco ...
Phys.org / Black locust deploys peptides to steer root bacteria into nitrogen fixation
Plants need nitrogen to grow. Many legumes meet this need through a symbiotic relationship: They harbor bacteria that fix atmospheric nitrogen and make it available to the plant. Until now, it was largely unclear how a perennial ...
Phys.org / Newly discovered corn trait may help improve crop drought tolerance
Researchers report some corn plants are genetically predisposed to develop longer, less constricted water-conducting tissues and deeper roots, which helps them deal with drought. That's the conclusion of a team led by Penn ...
Phys.org / Jellyfish reveal rapid repair system behind scar-free healing
A decade ago this summer, at the Marine Biological Laboratory, Jocelyn Malamy watched jellyfish cells "walk" toward each other to close a wound for the first time. An associate professor of molecular genetics and cell biology ...
Phys.org / Scientists teach human cells to compute like tiny computers
Researchers have developed a way to program human cells to perform calculations and make autonomous decisions, similar to how computer chips work.
Phys.org / One‑step process generates high entropy alloy nanoparticles in milliseconds for catalyst creation
A University at Buffalo-led team of researchers has developed a method for producing advanced nanoparticles that could accelerate the discovery of new materials for energy and electronic applications. The study, published ...
Phys.org / Bacteria use linked motors to reel in resistance DNA with extreme force
Every year, bacteria kill more than a million people worldwide through infections that no longer respond to antibiotics. In many cases, why those bacteria are so hard to stop comes down to their uniquely powerful structure.
