| Posted: 13 Aug 2021 03:38 PM PDT Thousands of COVID-19 cases and deaths in California, Oregon, and Washington between March and December 2020 may be attributable to increases in fine particulate air pollution (PM2.5) from wildfire smoke, according to a new study. |
| Sensor spies hideouts for ?virus replication Posted: 13 Aug 2021 03:07 PM PDT Some types of RNA viruses cloak themselves to hide inside a cell and create copies of themselves. But an enzyme that acts as a virus sensor might be attuned to their whereabouts. A slight variation in their genomic code gives some people's cells the capacity to produce this sensor. Researchers discovered how this sensor helps cells stop the virus before it multiplies too greatly. |
| July was Earth's hottest month on record: NOAA Posted: 13 Aug 2021 01:48 PM PDT July 2021 was the world's hottest month ever recorded, according to new global data released by NOAA's National Centers for Environmental Information. |
| Crop insurance and unintended consequences Posted: 13 Aug 2021 12:20 PM PDT A new study suggests that crop insurance serves as a disincentive for farmers to adopt climate change mitigation measures on their croplands. |
| For trees, carbs are key to surviving insect defoliation, study finds Posted: 13 Aug 2021 12:20 PM PDT Research reveals that a tree's carbohydrate reserves are crucial to surviving an onslaught of hungry caterpillars. |
| Three-layered control of mRNA tails Posted: 13 Aug 2021 12:20 PM PDT Researchers have characterized how the essential mRNA poly(A) tails are synthesized in the budding yeast Saccharomyces cerevisiae. The study reveals several mechanisms controlling poly(A) tail lengths and hereby ensuring the robustness of gene expression. |
| Microbial study reveals extended lifespan of starved bacteria Posted: 13 Aug 2021 12:20 PM PDT New research shows how bacteria can overcome starvation situations and survive for an extended period, which has broader implications for chronic infections. |
| Navigating the corn maze: Researchers develop technique to map out 'light switches' of maize genome Posted: 13 Aug 2021 12:19 PM PDT Getting a full understanding of how genes are regulated is a major goal of scientists worldwide. Now, researchers have developed a technique that can map out nearly all of the likely regulatory switches across a genome. |
| Scientists take step to improve crops’ photosynthesis, yields Posted: 13 Aug 2021 12:19 PM PDT A new study describes a significant step toward improving photosynthesis and increasing yields by putting elements from cyanobacteria into crop plants. |
| Researchers solve structure of BRCA2 protein complex important in DNA repair Posted: 13 Aug 2021 09:00 AM PDT The initials BRCA2 may be best known for a gene associated with many cases of breast cancer, and the protein encoded by the BRCA2 gene is critical to repairing breaks in DNA. The breakdown of this interaction is a hallmark of many cancers. Now scientists have determined the structure of a complex of two proteins -- BRCA2 together with MEILB2 -- that allows repairs to happen efficiently in cells undergoing cell-splitting, called meiosis. Their results have major implications for cancer and infertility. |
| Cats prefer to get free meals rather than work for them Posted: 13 Aug 2021 07:03 AM PDT When given the choice between a free meal and performing a task for a meal, cats would prefer the meal that doesn't require much effort. |
| Posted: 13 Aug 2021 07:03 AM PDT The precise transmission of genetic information from one generation to the next is fundamental to life. Most of the time, this process unfolds with remarkable accuracy, but when it goes awry, mutations can arise—some of them beneficial, some of them inconsequential, and some of them causing malfunction and disease. |
| Team of disease ecologists documents person-to-person spread of antimicrobial-resistant plague Posted: 13 Aug 2021 07:03 AM PDT A team of scientists recently published their findings from a remarkable study involving antimicrobial resistant (AMR) plague. |
| New algorithm can help improve cellular materials design Posted: 13 Aug 2021 07:03 AM PDT New research has revealed that a simple but robust algorithm can help engineers to improve the design of cellular materials that are used in a variety of diverse applications ranging from defense, bio-medical to smart structures and the aerospace sector. |
| Genetic program protects neurons from degeneration Posted: 13 Aug 2021 07:03 AM PDT Researchers have identified a previously unknown genetic program in the fruit fly. The genetic material involved controls the development of the neurons while also protecting them from degeneration. They have hardly changed in the course of evolution over hundreds of millions of years and also exist in a comparable form in humans. Initial data show that they presumably perform similar tasks there. The results may therefore also provide a starting point for new active ingredients for neurodegenerative diseases. |
| Farmers help create ‘Virtual safe space’ to save bumblebees Posted: 13 Aug 2021 07:03 AM PDT Solutions to help pollinators can be tested using a 'virtual safe space' tool created by scientists at the University of Exeter in collaboration with farmers and land managers. |
| Humans aren’t the only species whose metabolisms tend to slow down with age Posted: 13 Aug 2021 07:03 AM PDT If you feel like your metabolism just isn't what it used to be, no matter how many hours you spend in the gym, dolphins can relate. A new study finds that bottlenose dolphins burn calories at a lower rate as they get older, just like we do. |
| Effectively removing CO2 from the atmosphere Posted: 13 Aug 2021 07:02 AM PDT Researchers have investigated the extent to which direct capture of carbon dioxide (CO2) from the ambient air can help to effectively remove greenhouse gases from the atmosphere. The result: With careful planning, for example with regard to location and provision of the necessary energy, CO2 can be removed in a climate-effective manner. |
| Southeastern U.S. gray foxes may be struggling for survival Posted: 12 Aug 2021 01:18 PM PDT A new study suggests competition for food from coyotes -- a relative newcomer to the Southeast -- may be putting pressure on foxes, particularly the gray fox. |
| New marmoset species discovered in Brazilian Amazon Posted: 12 Aug 2021 01:18 PM PDT A team of scientists has discovered a new marmoset species in the Brazilian Amazon. Schneider's marmoset is named after professor Horacio Schneider, a pioneer and major contributor to the research of diversity and evolution of monkeys. |
| Unprecedented peek into life of 17,000-year-old mammoth Posted: 12 Aug 2021 11:50 AM PDT An international research team has retraced the astonishing lifetime journey of an Arctic woolly mammoth, which covered enough of the Alaska landscape during its 28 years to almost circle the Earth twice. |
| New enzyme that infects plants identified, paving the way for potential disease prevention Posted: 12 Aug 2021 11:50 AM PDT Scientists have identified an unusual enzyme that plays a major role in the infection of plants - and have shown that disabling this enzyme effectively stops plant disease in its tracks. |
| Research shows flocking birds, schooling fish, other collective movements can stabilize ecosystems Posted: 12 Aug 2021 10:59 AM PDT In addition to being visually stunning, schools of herring, herds of wildebeest and countless other groups of organisms that act in concert can help complex ecosystems maintain their diversity and stability. |
| Low-cost 3D method rapidly measures disease impacts on Florida’s coral reefs Posted: 12 Aug 2021 06:27 AM PDT A low-cost and rapid 3D technique is helping scientists to gain insight into the colony- and community-level dynamics of the poorly understood stony coral tissue loss disease responsible for widespread coral death throughout the Tropical Western Atlantic. They adapted Structure-from-Motion (SfM) photogrammetry to generate 3D models for tracking lesion progression and impacts on diseased coral colonies. They combined traditional diver surveys with 3D colony fate-tracking to determine the impacts of disease on coral colonies throughout Southeast Florida. |
