Glaciologists show evidence of warm ocean water intruding kilometers beneath grounded ice at Thwaites Glacier in West Antarctica. The findings suggest that existing climate models are underestimating the impact of ocean and ice interactions in future sea level rise projections.
Modern plant enzyme partners with surprisingly ancient protein
Scientists have discovered that a protein responsible for the synthesis of a key plant material evolved much earlier than suspected. This new research explored the origin and evolution of the biochemical machinery that builds lignin, a structural component of plant cell walls with significant impacts on the clean energy industry.
Better medical record-keeping needed to fight antibiotic overuse
A lack of detailed record-keeping in clinics and emergency departments may be getting in the way of reducing the inappropriate use of antibiotics, a pair of new studies suggests. In one of the studies, about 10% of children and 35% of adults who got an antibiotic prescription during an office...
Sweet taste receptor affects how glucose is handled metabolically by humans
The sweet-taste receptor might be the first stop in a metabolic surveillance system for sugar. The receptor is also expressed in certain intestinal cells, where it may facilitate glucose absorption and assimilation, as part of this system. A team found that stimulation and inhibition of the sweet receptor helps regulate...
Copper Can’t Be Mined Fast Enough to Electrify the US
Copper cannot be mined quickly enough to keep up with current U.S. policy guidelines to transition the country’s electricity and vehicle infrastructure to renewable energy, according to a University of Michigan study.
How Heatwaves Are Affecting Arctic Phytoplankton
The basis of the marine food web in the Arctic, the phytoplankton, responds to heatwaves much differently than to constantly elevated temperatures.
Researchers Confirm Scale Matters in Determining Vulnerability of Freshwater Fish to Climate Changes
The silver chub isn’t considered sensitive to climate change on a national scale, but context matters.
Fruit fly wing research offers window into birth defects
If fruit fly wings do not develop into the right shape, the flies will die. Researchers have learned how fly embryo cells develop as they need to, opening a window into human development and possible treatments for birth defects.
Plants restrict use of ‘Tipp-Ex proteins’
Plants have special corrective molecules at their disposal that can make retrospective modifications to copies of genes. However, it would appear that these 'Tipp-Ex proteins' do not have permission to work in all areas of the cell, only being used in chloroplasts and mitochondria. A study has now explained why...
Zombie cells in the sea: Viruses keep the most common marine bacteria in check
Marine microbes control the flux of matter and energy essential for life in the oceans. Among them, the bacterial group SAR11 accounts for about a third of all the bacteria found in surface ocean waters. A study now reveals that at times nearly 20% of SAR11 cells are infected by...
