Phys.org / Severe floods cut global rice yields, threatening food security for billions
Severe flooding has slashed global rice yields in recent decades, threatening food security for billions of people who depend on the grain. The losses amounted to approximately 4.3%, or 18 million tons of rice per year, between ...
Phys.org / Light intensity steers molecular assemblies into 1D, 2D or 3D structures
Constructing out-of-equilibrium molecular assemblies that deviate from thermodynamic equilibrium is a central challenge in materials science. While numerous studies have reported the creation of such states using external ...
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 / Know when to fold 'em: Study reveals benefits of dropping unrealistic goals
Though many people may benefit from setting life goals, new research led by Curtin University has revealed working towards unachievable targets could in fact have a negative impact on overall well-being—and knowing when ...
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 / 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 / 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 / Nearly 47 million Americans at high risk of potential health hazards from fossil fuel infrastructure, study finds
Fossil fuels release pollutants into the air when extracted and burned, but there's more to their production than massive oil rigs diving deep into Earth and smoky power plants. Those processes are examples of only the first ...
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 / 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 / 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 / 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, ...
