Phys.org / Sugar transporters found to boost aminoglycoside antibiotic entry into bacteria
Aminoglycosides are antibiotics effective against a wide range of bacteria including Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. Until now however, their mode of entry into bacteria has remained unknown. ...
Phys.org / Reducing arsenic in drinking water cuts risk of death, even after years of chronic exposure: 20-year study
A 20-year study of nearly 11,000 adults in Bangladesh found that lowering arsenic levels in drinking water was associated with up to a 50% lower risk of death from heart disease, cancer and other chronic illnesses, compared ...
Phys.org / Wastewater from 47 countries often suppresses resistant bacteria, challenging common assumptions
Municipal wastewater contains a large range of excreted antibiotics and has therefore long been suspected to be a spawning ground for antibiotic-resistant bacteria. Now, a study led by a team from the University of Gothenburg ...
Phys.org / California beaches are holding steady or gaining width, showing more resilience than expected
Two new studies from researchers at UC San Diego's Scripps Institution of Oceanography provide encouraging news about California's beaches at both local and statewide scales.
Phys.org / Sociology, meet ecology: How the variability of coffee harvests can teach us about sustainable farming
The rootstock of a coffee plant can live for 20 to 30 years. In that time, a generation, it will have good years and bad years, years where it bears large quantities of fruit and years where it fails to produce as expected.
Phys.org / 30-year 'snapshot' of Pacific Northwestern birds shows their surprising resilience
A 30-year "snapshot study" of birds in the Pacific Northwest is showing their surprising resilience in the face of climate change. The project started when School of Biological Sciences Assistant Professor Benjamin Freeman ...
Phys.org / Long-nosed Pinocchio chameleon fooled researchers—two new species identified
Genetic and morphological studies revealed two new chameleon species. One of them with a very long nose finally receives the scientific name that suits it—Calumma pinocchio. An international research team led by SNSB zoologist ...
Phys.org / A microbial blueprint for climate-smart cows
Each year, a single cow can belch about 200 pounds of methane. The powerful greenhouse gas is 27 times more potent at trapping heat in the atmosphere than carbon dioxide. For decades, scientists and farmers have tried to ...
Phys.org / From warriors to healers: Muscle stem cell signal redirects macrophages toward tadpole tail regeneration
Researchers Sumika Kato, Takeo Kubo, and Taro Fukazawa of the University of Tokyo have discovered that c1qtnf3, a secreting factor, namely a protein molecule that is secreted by a cell and influences functions of other cells, ...
Phys.org / Interface-driven catalyst design combines clean hydrogen production and urea conversion
Prof. Pi-Tai Chou's group at National Taiwan University Department of Chemistry has created a catalyst that turns two challenges into one solution: it produces clean hydrogen with remarkable efficiency while breaking down ...
Phys.org / Iron-sulfur cluster found essential for proper ribosome assembly in cells
A single iron-sulfur building block directly determines whether ribosomes—the protein factories of our cells—work smoothly or not. This is the conclusion of a recent research project led by the RPTU Kaiserslautern-Landau. ...
Phys.org / Lab setup mimics Arctic erosion to find out why shorelines are crumbling
Arctic coastlines are falling into the sea. Wave action, rising sea levels, and thawing permafrost are all contributing to the massive erosion that has forced whole towns to move farther from the water's edge.
