NASA-NOAA's Suomi NPP satellite provided a nighttime look at Hurricane Nana just after it began making landfall in Belize.
University of Calgary scientists have discovered how to capture "live" images of immune cells inside the lungs. The group at the Snyder Institute for Chronic Diseases at the Cumming School of Medicine is the first in the world to find a way to record, in real time, how the immune system battles bacteria impacting the alveoli, or air sacs, in the lungs of mice. The discovery has already provided new insights about the immune systems' cleaners, called alveolar macrophages.
What would you do if you knew how long you had until Alzheimer's disease set in? Don't despair. New research from the University of California, Berkeley, suggests one defense against this virulent form of dementia -- for which no treatment currently exists -- is deep, restorative sleep, and plenty of it.
UC Berkeley neuroscientists Matthew Walker and Joseph Winer have found a way to estimate, with some degree of accuracy, a time frame for when Alzheimer's is most likely to strike in a person's lifetime.
ITHACA, N.Y. - New research from Cornell University developed potential roadmaps for how the coronavirus infects organs and identifies what molecular factors could help facilitate or restrict infection.
"The data suggest that it's not just a respiratory disease," said lead author Cedric Feschotte, molecular biology professor. "It's much broader than that and has the potential to affect many other organs. Our analyses suggest that there is a wide range of cellular vulnerabilities."
New Orleans, LA - A team of LSU Health New Orleans radiologists investigated the usefulness of chest x-rays in COVID-19 and found they could aid in a rapid diagnosis of the disease, especially in areas with limited testing capacity or delayed test results. Their findings are published in Radiology: Cardiothoracic Imaging, available here.
Little is known about what determines strategy implementation around quality improvement (QI) in small and medium-sized primary care practices. New research led by George Mason University's College of Health and Human Services found that independent, physician-owned practices, adopted more QI strategies than hospital-owned practices and community clinics.
If naked mole-rats were human, they would be prescribed hearing aids. With six mutations in genes associated with hearing, naked mole-rats can barely hear the constant squeaking they use to communicate with one another. This hearing loss, which is strange for such social, vocal animals, is an adaptive, beneficial trait, according to new findings published in the journal Current Biology.
GAINESVILLE, Fla. --- Some male butterflies go to extreme lengths to ensure their paternity - sealing their mate's genitalia with a waxy "chastity belt" to prevent future liaisons. But female butterflies can fight back by evolving larger or more complex organs that are tougher to plug. Males, in turn, counterattack by fastening on even more fantastic structures with winglike projections, slippery scales or pointy hooks.
It's a battle that pits male and female reproductive interests against one another, with the losing sex evolving adaptations to thwart the winner's strategies.
PHILADELPHIA (September 3, 2020) - Adolescence is a difficult period of development, made more complex for those with Type 1 diabetes mellitus (T1DM). The challenges of managing multiple doses of daily insulin administration, blood glucose monitoring, dietary and exercise requirements, can make self-care difficult and complicate outcomes. Adolescents with T1DM often have poorer diabetes outcomes than others, indicating that glucose control is difficult for them to maintain.
ITHACA, N.Y. - People enjoy witnessing extraordinary individuals - from athletes to CEOs -extend long runs of dominance in their fields, but they aren't as interested in seeing similar streaks of success by teams or groups, according to new research from Cornell University.
Adding noise to enhance a weak signal is a sensing phenomenon common in the animal world but unusual in manmade sensors. Now Penn State researchers have added a small amount of background noise to enhance very weak signals in a light source too dim to sense.
In contrast to most sensors, for which noise is a problem that should be suppressed, they found that adding just the right amount of background noise can actually increase a signal too weak for sensing by normal sensors, to a level that can reach detectability.
Researchers develop first-ever battery-free, energy-harvesting, interactive device
Looking and feeling like an 8-bit Nintendo Game Boy, the device can play games straight from their original cartridges
Ultimate goal of battery-free computing is to reduce society's reliance on batteries, which are costly, environmentally hazardous and end up in landfills
EVANSTON, Ill. -- A hand-held video game console allowing indefinite gameplay might be a parent's worst nightmare.
Leesburg, VA, September 3, 2020--According to ARRS' American Journal of Roentgenology (AJR), nearly half (47.7%) of the research articles published in major radiology journals declared funding--a proportion that has increased from 17% of articles in 1994 and 26.9% published between 2001 and 2010.
Short-term flooding from extreme storm events poses a serious transportation challenge in U.S. cities. This problem--which is anticipated to grow over the next century with our global climate crisis--is often hardest on vulnerable populations, including low-income and minority neighborhoods.
HOUSTON - (Sept. 3, 2020) - Nature's speed limits aren't posted on road signs, but Rice University physicists have discovered a new way to deduce them that is better -- infinitely better, in some cases -- than previous methods.
"The big question is, 'How fast can anything -- information, mass, energy -- move in nature?'" said Kaden Hazzard, a theoretical quantum physicist at Rice. "It turns out that if somebody hands you a material, it is incredibly difficult, in general, to answer the question."
