Published Asian aerosols' impact on Atlantic Meridional Overturning Circulation
(via sciencedaily.com) Original source A new study identifies the role aerosols over Asia is having on the AMOC, a complex system of currents in the Atlantic Ocean.
Published Tryptophan in diet, gut bacteria protect against E. coli infection
(via sciencedaily.com) Original source Gut bacteria and a diet rich in the amino acid tryptophan can play a protective role against pathogenic E. coli, which can cause severe stomach upset, cramps, fever, intestinal bleeding and renal failure.
Published Interactions with dogs can increase brainwaves associated with stress relief and heightened concentration
(via sciencedaily.com) Original source Spending quality time with dogs reduces stress and increases the power of brain waves associated with relaxation and concentration, according to a new study.
Published Menopause explains why some female whales live so long
(via sciencedaily.com) Original source Females of some whale species have evolved to live drastically longer lives so they can care for their families, new research shows.
Published Study shows important role gut microbes play in airway health in persons with cystic fibrosis
(via sciencedaily.com) Original source Findings from a new study reflect the important role that the gut microbiome (communities of bacteria) plays in the airway health of persons with cystic fibrosis.
Published With discovery of roundworms, Great Salt Lake's imperiled ecosystem gets more interesting
(via sciencedaily.com) Original source Biologists announce the discovery of numerous species of roundworm in the highly saline waters of Great Salt Lake, the vast terminal lake in northwestern Utah that supports millions of migratory birds. Previously, brine shrimp and brine flies were the only known multicellular animals living in the water column. The scientists found nematodes, belonging to a family known for inhabiting extreme environments, in the lake's microbialites, reef-like structures covering about a fifth of the lakebed.
Published Marine heat waves disrupt the ocean food web in the northeast Pacific Ocean
(via sciencedaily.com) Original source Marine heat waves in the northeast Pacific Ocean create ongoing and complex disruptions of the ocean food web that may benefit some species but threaten the future of many others, a new study has shown.
Published Drought, soil desiccation cracking, and carbon dioxide emissions: an overlooked feedback loop exacerbating climate change
(via sciencedaily.com) Original source Soil stores 80 percent of carbon on earth, yet with increasing cycles of drought, that crucial reservoir is cracking and breaking down, releasing even more greenhouse gases creating an amplified feedback loop that could accelerate climate change.
Published 'Find pearls in the soil' unveiling the magic of hydrogen production from municipal sewage
(via sciencedaily.com) Original source Scientists have developed a catalyst for the urea oxidation reaction, enhancing hydrogen generation efficiency.
Published Steroid drugs used for HRT can combat E. coli and MRSA
(via sciencedaily.com) Original source Researchers have combined computational and microbiology laboratory approaches to identify existing drugs that can be repurposed to combat antibiotic-resistant bacterial infections. This research has revealed that a class of steroid drugs currently used in hormone replacement therapy (HRT) can also stop the growth of antibiotic-resistant E. coli and effectively kill MRSA.
Published New computational strategy boosts the ability of drug designers to target proteins inside the membrane
(via sciencedaily.com) Original source Hitting targets embedded within the cell membrane has long been difficult for drug developers due to the membrane's challenging biochemical properties. Now, chemists have demonstrated new custom-designed proteins that can efficiently reach these 'intramembrane' targets.
Published High resolution imagery advances the ability to monitor decadal changes in emperor penguin populations
(via sciencedaily.com) Original source Emperor penguin populations have been exceedingly difficult to monitor because of their remote locations, and because individuals form breeding colonies on seasonal sea ice fastened to land (known as fast ice) during the dark and cold Antarctic winter. New research that incorporates very high-resolution satellite imagery with field-based validation surveys and long-term data has provided the first multi-year time series that documents emperor penguin global population trends.
Published Sonic youth: Healthy reef sounds increase coral settlement
(via sciencedaily.com) Original source Healthy coral reefs have rich soundscapes, full of the croaks, purrs, and grunts of various fishes and the crackling of snapping shrimp. Larval coral uses these sounds as cues to identify the best places to settle and grow. The authors found that sound could potentially be a vital tool in the effort to restore coral reefs. Broadcasting the sounds of a healthy reef to a reef that is degraded encourages coral larvae to settle there. This indicates that it's possible that 'acoustic enrichment' can be a key intervention to support imperiled reefs.
Published Simple trick could improve accuracy of plant genetics research
(via sciencedaily.com) Original source Researchers have published a simple trick that improves the accuracy of techniques that help us understand how external variables -- such as temperature -- affect gene activity in plants.
Published Milk to the rescue for diabetics? Cow produces human insulin in milk
(via sciencedaily.com) Original source An unassuming brown bovine from the south of Brazil has made history as the first transgenic cow capable of producing human insulin in her milk. The advancement could herald a new era in insulin production, one day eliminating drug scarcity and high costs for people living with diabetes.
Published Grounding zone discovery explains accelerated melting under Greenland's glaciers
(via sciencedaily.com) Original source Researchers have conducted the first large-scale observation and modeling study of northwest Greenland's Petermann Glacier. Their findings reveal the intrusion of warm ocean water beneath the ice as the culprit in the accelerated melting it has experienced since the turn of the century, and their computer predictions indicate that potential sea level rise will be much worse than previously estimated.
Published Study brings scientists a step closer to successfully growing plants in space
(via sciencedaily.com) Original source New, highly stretchable sensors can monitor and transmit plant growth information without human intervention. The polymer sensors are resilient to humidity and temperature, can stretch over 400% while remaining attached to a plant as it grows and send a wireless signal to a remote monitoring location, said a chemical and biomolecular engineering professor.
Published Tsetse fly fertility damaged after just one heatwave, study finds
(via sciencedaily.com) Original source The fertility of both female and male tsetse flies is affected by a single burst of hot weather, researchers have found.
Published A simple and robust experimental process for protein engineering
(via sciencedaily.com) Original source A protein engineering method using simple, cost-effective experiments and machine learning models can predict which proteins will be effective for a given purpose, according to a new study.
Published Who knew that coprophagy was so vital for birds' survival?
(via sciencedaily.com) Original source New research explains how eating feces (known as coprophagy) shapes wild birds' digestive tracts (gut biota), enabling them to absorb lost or deficient nutrients and adjust to seasonal variations in food sources.
