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 / 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 / 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 / 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 / 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 / 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.
Phys.org / Scientists pinpoint single gene responsible for initiating winter behavior of mammals
As the days continue to get shorter, scientists have made a significant discovery in understanding exactly what makes mammals exhibit seasonal behaviors like hibernation and migration.
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 / Key corn protein linked to stronger, longer-lasting seed
A new international study co-led by the University of Kentucky Martin-Gatton College of Agriculture, Food and Environment shows how a single genetic change helps protect corn seeds during storage. This offers plant breeders ...
Phys.org / New photonic chips passively convert laser light into multiple colors on demand
Over the past several decades, researchers have been making rapid progress in harnessing light to enable all sorts of scientific and industrial applications. From creating stupendously accurate clocks to processing the petabytes ...
Phys.org / Cosmic ray puzzle resolved as scientists link 'knee' formation to black holes
Milestone results released by the Large High Altitude Air Shower Observatory (LHAASO) on November 16 have solved a decades-old mystery about the cosmic ray energy spectrum—which shows a sharp decrease in cosmic rays above ...
