Phys.org / Prescribed burning helps store forest carbon in big fire-resistant trees, long-term Sierra Nevada study shows
A two-decade-long experiment in the Sierra Nevada found that regular prescribed burns promote carbon sequestration in live trees and plants, maintaining forests' long-term ability to store carbon while also reducing wildfire ...
Phys.org / Traditional Hawaiian fishponds help shield fish from climate change impacts
Traditional Hawaiian fishponds (loko iʻa) are emerging as a model for climate resilience, according to a study from the University of Hawaiʻi at Mānoa's Hawaiʻi Institute of Marine Biology (HIMB). The research, published ...
Phys.org / Beyond the usual suspect: Nitrogen feeds algae blooms, researchers find
Nitrogen is a bit of a conundrum. In its gaseous form it's the most abundant element in the atmosphere, but few organisms can readily use it. And while all living organisms contain nitrogen, a new University of Vermont study ...
Phys.org / Molecular switch helps cancer cells survive harsh conditions
Cells are regularly faced with environmental stresses that may damage or destroy them. To survive, they quickly adjust their gene expression to protect themselves. This is especially true for cancer cells, which must contend ...
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 ...
