Published A wetter world recorded in Australian coral colony
(via sciencedaily.com) Original source When climate scientists look to the future to determine what the effects of climate change may be, they use computer models to simulate potential outcomes such as how precipitation will change in a warming world. Some scientists are also looking at something a little more tangible: coral.
Published Transforming wood waste for sustainable manufacturing
(via sciencedaily.com) Original source Research is exploring how to add value to lignin by breaking it down into small molecules that are structurally similar to oxygenated hydrocarbons. These renewable chemicals are key components in many industrial processes and products, but they are traditionally sourced from non-renewable petroleum.
Published How cells are ahead of the curve
(via sciencedaily.com) Original source The curvature of a surface determines the migration behavior of biological cells. They preferentially move along valleys or grooves while avoiding ridges. These findings gave rise to a model predicting cellular behavior. Such universal principles now allow a better understanding of the migration of immune and cancer cells, paving the way for new treatment options.
Published Study estimates nearly 70 percent of children under six in Chicago may be exposed to lead-contaminated tap water
(via sciencedaily.com) Original source A new analysis estimates that 68 percent of Chicago children under age six live in households with tap water containing detectable levels of lead.
Published Even inactive smokers are densely colonized by microbial communities
(via sciencedaily.com) Original source Everything is everywhere -- under certain conditions microbial communities can grow and thrive, even in places that are seemingly uninhabitable. This is the case at inactive hydrothermal vents on the sea floor. An international team is presently working to accurately quantify how much inorganic carbon can be bound in these environments.
Published Machine learning classifier accelerates the development of cellular immunotherapies
(via sciencedaily.com) Original source Making a personalized T cell therapy for cancer patients currently takes at least six months. Scientists have shown that the laborious first step of identifying tumor-reactive T cell receptors for patients can be replaced with a machine learning classifier that halves this time.
Published Protein fragments ID two new 'extremophile' microbes--and may help find alien life
(via sciencedaily.com) Original source Perfectly adapted microorganisms live in extreme environments from deep-sea trenches to mountaintops. Learning more about how these extremophiles survive in hostile conditions could inform scientists about life on Earth and potential life on other planets.
Published Groundbreaking study reveals extensive leatherback turtle activity along U.S. coastline
(via sciencedaily.com) Original source A new study provides groundbreaking findings that offer insights on the migration and foraging patterns of leatherback sea turtles along the Northwest Atlantic shelf.
Published New study on mating behaviors offers clues into the evolution of attraction
(via sciencedaily.com) Original source In examining the mating rituals of roundworms, researchers uncovered a unique approach to reproduction that maximizes genetic fitness.
Published It's hearty, it's meaty, it's mold
(via sciencedaily.com) Original source Scientists are exploring how tuning the genomes of mushrooms and molds can transform these food sources into gourmet, nutrient-packed meals made with minimal processing and a light environmental footprint.
Published New discovery reveals how the egg controls sperm entry
(via sciencedaily.com) Original source After the egg has been fertilized by a sperm, the surrounding egg coat tightens, mechanically preventing the entry of additional sperm and the ensuing death of the embryo, a new study finds. The work also explains how mutations in egg coat proteins can cause female infertility and may eventually lead to new contraceptive methods.
Published Sulfur and the origin of life
(via sciencedaily.com) Original source A new study shines a spotlight on sulfur, a chemical element that, while all familiar, has proved surprisingly resistant to scientific efforts in probing its role in the origin of life.
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 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 Sustainable plastics from agricultural waste
(via sciencedaily.com) Original source Scientists have developed a sustainable method to make high-performance plastics from agricultural leftovers, turning them into valuable materials.
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 Molecular simulations of ammonia mixtures support search for renewable fuels
(via sciencedaily.com) Original source Ammonia is an important molecule with many applications. The end product of the famed Haber-Bosch process, it is commonly synthesized to capture nitrogen for fertilizers, and is used for refrigeration, in cleaning products, and in the production of pharmaceuticals. Recently, this modest molecule has also attracted interest as a potential resource for addressing one of today's most pressing challenges -- the need for reliable and abundant renewable fuels.
Published New high-performance solar cell material
(via sciencedaily.com) Original source A new study reports the discovery of an entirely new stable, earth-abundant, high-performance material for solar absorbers -- the central part of a solar cell that turns light into electricity. While identifying new solar materials is typically very time-consuming, the researchers used a unique high-throughput computational screening method to quickly evaluate around 40,000 candidate materials.
Published AI analysis of historical satellite images show USSR collapse in 1990s increased methane emissions, despite lower oil and gas production
(via sciencedaily.com) Original source An AI-powered analysis of 25 years of satellite images yields the surprising finding that methane emissions in Turkmenistan, a former Soviet republic and major oil-producing region, actually increased in the years following the dissolution of the Soviet Union.
Published Vehicle brakes produce charged particles that may harm public health
(via sciencedaily.com) Original source Scientists know relatively little about particles released into the air when a vehicle driver brakes, though evidence suggests those particles may be more harmful to health than particles exiting the tailpipe.
