Phys.org / Bacterial enzyme switch could weaken antibiotic defenses in MRSA and other pathogens
If you ask Vijay Parashar, associate professor of medical and molecular sciences (MMSC) at the University of Delaware College of Health Sciences, human bodies are bags of bacteria. "It sounds gross, but not all bacteria are ...
Phys.org / One-third of agricultural land accounts for two-thirds of global impact, study reveals
Agriculture covers more than 40% of Earth's habitable land and plays a central role in both climate change and biodiversity loss. Yet the impact of agriculture is far from evenly distributed across space.
Phys.org / Siberia's growing methane threat could offset 20% of global methane reduction targets by 2050
The Arctic is warming at an accelerating pace. As permafrost thaws across vast areas and wildfires become more frequent, large amounts of methane (CH4) are being released. Together, these changes are reshaping the region's ...
Phys.org / How 'smart' hydrogel packaging tells you if your food is still fresh
The cuts of meat in a supermarket case can look perfectly fresh even as bacteria are already multiplying inside the package. Is there a way to know before you open it?
Phys.org / Liquid nitrogen may have recently flowed across Pluto's heart-shaped glacier
A new study led by Southwest Research Institute (SwRI) provides evidence that liquid nitrogen is rising to Pluto's surface through cracks at the northern edge of Sputnik Planitia, part of the massive heart-shaped glacier ...
Phys.org / Carbon nanostructure improves fuel-cell catalyst durability while reducing platinum use
The explosion of new data centers being proposed and built around the U.S. has increased demand for energy to keep them powered and cooled. The Electric Power Research Institute estimates that data centers could consume up ...
Phys.org / Sugars may have helped fuel the evolution of the human brain, new research suggests
Fruit, honey and other naturally sweet foods may have helped fuel the evolution of the human brain, according to new research from the University of Sydney and the University of Glasgow.
Phys.org / Bioengineers develop biochemical halo to cloak insulin-producing cells from body defenses
A protein known as interleukin 10 (IL-10) is the lynchpin of a new method to protect transplanted cells from host immune system attacks. Rice University researchers engineered a living factory to produce a localized biochemical ...
Phys.org / Atomic view of Alzheimer's disease peptide could inform new drugs
One of the hallmarks of Alzheimer's disease is the accumulation of a peptide in the brain known as amyloid beta. A new study published in Nature Communications on July 22 has uncovered the atomic structure of the peptide ...
Phys.org / One ant can trigger colony-wide activity bursts, mathematical model suggests
Scientists have long known that ant colonies sometimes seem to move as one. A nest that appears quiet can suddenly erupt into activity, with workers throughout the colony springing into motion almost simultaneously before ...
Phys.org / AI and 'Ramanomics' could eliminate a major obstacle to studying living cells
Fluorescent dyes have long been used in biological research to identify and visualize structures within living cells. Although effective, they have several drawbacks, including altering the cells under study, limiting the ...
Phys.org / Sizing errors can hide true nanoparticle behavior
Nanoscience, which studies small objects, has a big problem. According to a team of scientists at the National Institute of Standards and Technology (NIST), the field confronts a pervasive data analysis error that can give ...
