MANHATTAN, KANSAS -- In a paper published Wednesday, Nov. 25, in Nature, Kansas State University researchers, in collaboration with the international 10+ Genome Project led by the University of Saskatchewan, have announced the complete genome sequencing of 15 wheat varieties representing breeding programs around the world -- an invaluable resource to improve global wheat production.
RENO, Nevada - Freshwater fish reserves are extraordinarily successful at protecting multiple species of fish, a new study of a network of community-based reserves in Thailand has found.
Aaron Koning, a postdoctoral research fellow at the University of Nevada, Reno's Global Water Center, spent seven years studying a network of freshwater protected areas (fish reserves) that communities established in one branch of the Salween River Basin in northern Thailand.
Boston, Mass. - Even as tens of thousands of Americans test positive for COVID-19 each day, physicians still aren't sure why some people experience mild to no symptoms while others become critically ill. New research led by Robert E. Gerszten, MD, Chief of the Division of Cardiovascular Medicine at Beth Israel Deaconess Medical Center (BIDMC) sheds new light on the genetic risk factors that make individuals more or less susceptible to severe COVID-19.
Wheat researchers at the John Innes Centre are pioneering a new technique that promises to improve gene discovery for the globally important crop.
The lives of patients hospitalised with COVID-19 are being saved by doctors who are using an existing medical treatment at an earlier stage.
Dr Luigi Sedda of Lancaster University analysed the results from the team at Wrightington, Wigan and Leigh Teaching Hospitals NHS Trust (WWL). Their research has now been published in the prestigious medical journal BMJ Respiratory Open.
The quantum sensing abilities of nanodiamonds can be used to improve the sensitivity of paper-based diagnostic tests, potentially allowing for earlier detection of diseases such as HIV, according to a study led by UCL researchers in the i-sense McKendry group.
DES PLAINES, IL -- Advanced practice providers (APPs) have lower productivity compared with emergency department physicians, seeing fewer and less complex patients and generating less relative value units per hour, and having no apparent impact on patient satisfaction and safety metrics. That is the conclusion of a study to be published in the November 2020 issue of Academic Emergency Medicine (AEM), a journal of the Society for Academic Emergency Medicine (SAEM).
The next time you visit a lake or the seashore, take a deep breath. As you exhale, take a moment to be thankful for the little things: specifically, for the microscopic, single-celled algae in the soil and waters all around you that are extracting the carbon dioxide you just exhaled and incorporating it into sugars that will eventually be used by every other organism in the biosphere. About 30% of this activity, globally, is carried out by a specialized structure in algae called the pyrenoid.
Despite their reputation, rats are surprisingly sociable and actually regularly help each other out with tasks. Researchers at the Universities of Göttingen, Bern and St Andrews have now shown that a rat just has to smell the scent of another rat that is engaged in helpful behaviour to increase his or her own helpfulness. This is the first study to show that just the smell of a cooperating individual rat is enough to trigger an altruistic and helpful response in another. The research was published in the Proceedings of the Royal Society B.
Astrophysicists from Far Eastern Federal University (FEFU) joined the international research team for explaining the difference in the results of observation of the comet 41P/ Tuttle - Giacobini - Kresak. Researchers believe that data obtained by three independent teams are complementary and its complex analysis helps to unravel the mystery of dust chemical composition of comet 41P and other conundrums of the Universe. A related article appears in Astronomy & Astrophysics.
The Loricifera is a microscopic, sediment-dwelling marine invertebrate, with a head covered in over 200 spines and an abdomen with a protective shell - known as a lorica. Since it was first discovered in 1983, just under 40 species have been written about. Now, that number is one more thanks to a group of scientists who reported on a new genus and species of Loricifera.
Their findings were published in the Journal Marine Biodiversity.
Perovskite solar cells are attracting attention as the next-generation solar battery material thanks to their low processing cost and excellent photovoltaic quality. However, it is difficult to commercialize them because their key material - perovskite - is vulnerable to light and moisture.
Recently, a POSTECH research team has developed an organic spacer molecular additive that can improve both the photoelectric efficiency and stability of perovskite.
Space-momentum domain interferometer is a key technique in modern precision measurements, and has been widely for applications that require superb spatial resolution in engineering metrology and astronomy. Extending such interferometric technique to the time-energy domain is a significant complement to spatial domain measurements and is anticipated to provide time resolving capability for tracing ultrafast processes.
Bottom Line: Among patients with glioblastoma receiving an immune checkpoint inhibitor, those who received the corticosteroid dexamethasone at baseline for cerebral edema had significantly worse overall survival.

OTTAWA, ON - NOV. 25, 2020 - A new study published in The BMJ shows that people who had surgery to improve blood flow in their legs under spinal or epidural anesthesia were less likely to die than those who were given general anesthesia.
General anesthesia involves using drugs to make a patient unconscious and inserting a tube into their windpipe to help with breathing. Spinal and epidural anesthesia directly freeze the nerves to the legs and can be combined with lighter forms of sedation which do not involve a breathing tube.
