| Scientists identify areas of high marine mammal diversity Posted: 04 Mar 2022 03:29 PM PST Sightings of more than 1 million marine mammals in the federally protected Northeast Canyons and Seamounts Marine National Monument and sites along the Atlantic Coast have been used to identify areas of high marine mammal diversity. These findings underscore the importance of ocean conservation as these waters face increasing impacts from human activities. |
| Possible common thread between many neurodegenerative diseases Posted: 04 Mar 2022 03:29 PM PST Researchers reveal a new fibril in diseased brains, one formed by a protein normally busy cleaning cells. |
| Event horizons are tunable factories of quantum entanglement Posted: 04 Mar 2022 03:29 PM PST Physicists have leveraged quantum information theory techniques to reveal a mechanism for amplifying, or 'stimulating,' the production of entanglement in the Hawking effect in a controlled manner. Furthermore, these scientists propose a protocol for testing this idea in the laboratory using artificially produced event horizons. |
| Meddling with metals: Escaping the tyranny of copper Posted: 04 Mar 2022 03:29 PM PST Researchers have reported a new protein-design strategy to sidestep the Irving-Williams Series, allowing proteins to behind to other metals ahead of copper. |
| Single test for over 50 genetic diseases will cut diagnosis from decades to days Posted: 04 Mar 2022 11:46 AM PST A single DNA test has been developed that can screen a patient's genome for over 50 genetic neurological and neuromuscular diseases such as Huntington's disease, muscular dystrophies and fragile X syndrome. The new test avoids a 'diagnostic odyssey' for patients that can take decades. The team has shown that the test is accurate. They are now working on validations to make it available in pathology labs. They expect it to be standard in global pathology labs within five years. |
| Visualizing the invisible: New fluorescent DNA label reveals nanoscopic cancer features Posted: 04 Mar 2022 11:46 AM PST Researchers have developed a new fluorescent label that gives a clearer picture of how DNA architecture is disrupted in cancer cells. The findings could improve cancer diagnoses for patients and classification of future cancer risk. |
| Making diversity, equity, inclusion integral part of physics education Posted: 04 Mar 2022 09:40 AM PST While many physics instructors are beginning to incorporate lessons on diversity, equity, and inclusion in the classroom, it can often feel like an add-on rather than an integral component of becoming a physicist. Scientists are helping to change this by presenting discussions and activities on DEI as a fundamental and essential part of physics training. The team created two approaches for DEI curriculum, replacing a question on a weekly homework assignment with a reflection essay on a topic important to physicists and including activities and discussions during a two-day unit on representation. |
| Changing the standard of care for stage III melanoma surgery Posted: 04 Mar 2022 09:40 AM PST For years, surgery for patients with stage III melanoma -- melanoma that has spread to the lymph nodes -- involved removing those lymph nodes along with the primary tumor. Known as completion lymph node dissection (CLND), the surgery was meant to ensure that no cancer remained after surgery. More recently, however, cancer surgeons have discovered that CLND has the potential to cause more problems than it solves. In most cases, patients do better on immunotherapy alone than they do when their surgery involves removal of the lymph nodes, due to potential complications from lymph node surgery. |
| Researchers map magnetic fields in 3D, findings could improve device storage capacity Posted: 04 Mar 2022 09:40 AM PST Researchers have mapped magnetic fields in three dimensions, a major step toward solving what they call the 'grand challenge' of revealing 3D magnetic configuration in magnetic materials. The work has implications for improving diagnostic imaging and capacity in storage devices. |
| Artificial intelligence predicts algae potential as alternative energy source Posted: 04 Mar 2022 09:40 AM PST Texas A&M AgriLife Research scientists are using artificial intelligence to set a new world record for producing algae as a reliable, economic source for biofuel that can be used as an alternative fuel source for jet aircraft and other transportation needs. |
| AI helped protect businesses from COVID-19 risks Posted: 04 Mar 2022 07:09 AM PST A new study has found that artificial intelligence (AI) apps helped protect small and medium-sized businesses against many of the risks that emerged during the COVID-19 pandemic -- yet only a quarter of small firms currently use them. |
| More alcohol, less brain: Association begins with an average of just one drink a day Posted: 04 Mar 2022 06:03 AM PST Even light-to-moderate drinking is associated with harm to the brain, according to a new study. Researchers analyzed data from more than 36,000 adults that found a link between drinking and reduced brain volume that begins at an average consumption level of less than one alcohol unit a day -- the equivalent of about half a beer -- and rises with each additional drink. |
| New research suggests a causal link between blood group and severe COVID-19 Posted: 03 Mar 2022 11:12 AM PST A new study has analysed over 3000 proteins to identify which are causally linked to the development of severe COVID-19. This is the first study to assess such a large number of proteins for their connection to COVID-19. The findings provide insight into potential new targets for approaches to treat and prevent severe COVID-19. |
| Researchers find 'genetic baggage' accumulates in the genomes of aging mutant animals Posted: 03 Mar 2022 11:12 AM PST You are probably familiar with the term that some people carry 'a lot of extra baggage.' Usually that term refers to that person's emotional history, but in genetics and our genomes, 'extra baggage' can also describe the transposons lurking in our genomes, a historical record of our genomes surviving traumatic invasions during evolution. Transposons are repetitive DNA sequences that have the capability to move (transpose) from one location to another in the genome (an organism's complete set of genetic instructions) and are considered important invaders of our genomes during evolution. |
| Cohorting patient care model during pandemic improved patient outcomes, researchers find Posted: 03 Mar 2022 09:50 AM PST Researchers found that, during the extenuating circumstances of an emerging pandemic, grouping patients together in one area or facility was successful in providing high-quality care and containing infectious patients. |
