| Sudden cardiac episodes could be caused by 'deadly cocktail' Posted: 02 Sep 2021 02:47 PM PDT It has been a mystery why some people live a perfectly normal life until experiencing a potentially deadly cardiac episode. Now, researchers present a possible explanation in a microscopic modification of a protein, which causes a mutation to turn harmful. The knowledge could help future diagnosis and drug regimens. |
| Many with food allergies don’t know about oral immunotherapy treatment option Posted: 02 Sep 2021 02:47 PM PDT A study of a geographically, clinically, and socioeconomically diverse, nationally-representative sample of US households -- including both adult patients and caregivers of children with food allergy -- found that 72 percent did not know what oral immunotherapy (OIT) was prior to the survey. Researchers also discovered that current OIT awareness is disproportionately elevated among wealthier, more highly educated respondents, which underscores the need for more equitable outreach efforts and greater access to these therapies for all patients with food allergies. |
| Testing 1-2: New laser-based microphone calibration measures up Posted: 02 Sep 2021 02:47 PM PDT Researchers have conducted the first demonstration of a faster and more accurate way to calibrate certain kinds of microphones. The technique, which uses lasers to measure the velocity at which a microphone's diaphragm vibrates, performs well enough to overtake one of the main calibration methods used. |
| Scientists discover a mechanism for memory transfer between individuals in C. elegans Posted: 02 Sep 2021 02:47 PM PDT Researchers demonstrated that the microscopic worm C. elegans uses a retrotransposon called Cer1 to transfer a learned behavior (avoidance of a pathogenic bacterium) between worms. |
| Mountaintop mining causes 40% loss of aquatic biodiversity Posted: 02 Sep 2021 02:47 PM PDT Using environmental DNA scans of Appalachian streams, researchers found that the effects of mountaintop coal mining in West Virginia are even more widespread than previously reported: Streams from heavily mined watersheds harbor 40% fewer species than streams with cleaner water. |
| Posted: 02 Sep 2021 02:47 PM PDT Vaccinations against human papillomavirus (HPV), a major cause of throat and back of mouth cancers, are expected to yield significant reductions in the rates of these cancers in the U.S., but will not do so until after 2045, according to a new modeling study. |
| Surprise result for solid state physicists hints at unusual electron behavior Posted: 02 Sep 2021 02:47 PM PDT While studying the behavior of electrons in iron-based superconducting materials, researchers observed a strange signal relating to the way electrons are arranged. The signal implies a new arrangement of electrons the researchers call a nematicity wave, and they hope to collaborate with theoretical physicists to better understand it. The nematicity wave could help researchers understand the way electrons interact with each other in superconductors. |
| Cavalier King Charles spaniels carry more harmful genetic variants than other breeds, study finds Posted: 02 Sep 2021 02:46 PM PDT Recent dog breeding practices have loaded up cavalier King Charles spaniels with disease-causing mutations, including variants linked to the common heart condition, myxomatous mitral valve disease (MMVD), according to new findings. |
| Stellar collision triggers supernova explosion Posted: 02 Sep 2021 02:46 PM PDT The Very Large Array Sky Survey gave astronomers the first clue that ultimately revealed a dramatic story -- the remnant of a star that exploded long ago had plunged into the core of its companion star causing it, too, to explode as a supernova. |
| Indian wolf among world’s most endangered and distinct wolves Posted: 02 Sep 2021 02:46 PM PDT The Indian wolf could be far more endangered than previously recognized, say first scientists to sequence its genome. Indian wolves could also represent the most ancient surviving lineage of wolves. |
| Putting a new theory of many-particle quantum systems to the test Posted: 02 Sep 2021 02:46 PM PDT New experiments using trapped one-dimensional gases -- atoms cooled to the coldest temperatures in the universe and confined so that they can only move in a line -- fit with the predictions of the recently developed theory of 'generalized hydrodynamics.' |
| Teenagers aren't as lonely in lockdown if interacting positively online, research finds Posted: 02 Sep 2021 02:46 PM PDT Parents and educators have long fretted over the amount of time children and teenagers spend online.
