Alexandria, Va., USA -- High-volume aspirators are recommended in dental clinics during the COVID-19 pandemic, but the study "SARS-CoV-2 Seropositivity Among Dental Staff and the Role of Aspirating Systems" published in the JDR Clinical & Translational Research (JDR CTR), shows that the type of aspirating system significantly affects the incidence of SARS-CoV-2 infection among dental specialists.
Systems designed to detect deepfakes --videos that manipulate real-life footage via artificial intelligence--can be deceived, computer scientists showed for the first time at the WACV 2021 conference which took place online Jan. 5 to 9, 2021.
The Atala butterfly (Eumaeus atala) and its five closest relatives in the genus Eumaeus like to display their toxicity. This sextet's toxicity comes from what they eat as caterpillars: plants called cycads that have been around since before dinosaurs roamed the Earth and contain a potent liver toxin called cycasin.
PITTSBURGH, Feb. 8, 2021 - With the aid of sophisticated machine learning, researchers at UPMC and the University of Pittsburgh School of Medicine demonstrated that a tool they developed can rapidly predict mortality for patients facing transfer between hospitals in order to access higher-acuity care. This research, published today in PLOS One, could help physicians, patients and their families avoid unnecessary hospital transfers and low-value treatments, while better focusing on the goals of care expressed by patients.
Economic growth is often prescribed as a sure way of increasing the well-being of people in low-income countries, but a study led by McGill and the Institute of Environmental Sciences and Technologies at the Universitat Autònoma de Barcelona (ICTA-UAB) suggests that there may be good reason to question this assumption. The researchers set out to find out how people rate their subjective well-being in societies where money plays a minimal role, and which are not usually included in global happiness surveys. They found that the majority of people reported remarkably high levels of happiness.
ITHACA, N.Y. - Soft robots may not be in touch with human feelings, but they are getting better at feeling human touch.
Cornell University researchers have created a low-cost method for soft, deformable robots to detect a range of physical interactions, from pats to punches to hugs, without relying on touch at all. Instead, a USB camera located inside the robot captures the shadow movements of hand gestures on the robot's skin and classifies them with machine-learning software.
URBANA, Ill. - From flooded spring fields to summer hailstorms and drought, farmers are well aware the weather is changing. It often means spring planting can't happen on time or has to happen twice to make up for catastrophic losses of young seedlings.
According to a joint study between University of Illinois and USDA-ARS, it also means common pre-emergence herbicides are less effective. With less weed control at the beginning of the season, farmers are forced to rely more heavily on post-emergence herbicides or risk yield loss.
A new study suggests that differences in the expression of gene transcripts - readouts copied from DNA that help maintain and build our cells - may hold the key to understanding how mental disorders with shared genetic risk factors result in different patterns of onset, symptoms, course of illness, and treatment responses. Findings from the study, conducted by researchers at the National Institute of Mental Health (NIMH), part of the National Institutes of Health, appear in the journal Neuropsychopharmacology.
PHILADELPHIA (February 8, 2021) - An abundance of data underscore the importance of breastfeeding and human milk for the optimal health of infants, children, mothers, and society. But while breastfeeding initiation rates have increased to more than 80% in the U.S., a disparity exists for African American mothers and infants. In this group, breastfeeding is initiated only about 69% of the time.
Oakland, Calif. -- An analysis of Kaiser Permanente members in Northern California early in the COVID-19 pandemic found racial and ethnic disparities in the likelihood of testing positive for the coronavirus, but no significant disparities in mortality among those who were hospitalized.
Faster speech rate, greater intensity in the middle of the word, and falling pitch at the end of the word: that is the prosody[1] to adopt if one wants to come across as reliable and honest to one's listeners. Scientists from the Science and Technology for Music and Sound laboratory (CNRS/Ircam/Sorbonne Université/Ministère de la Culture)[2] and the Perceptual Systems Laboratory (CNRS/ENS PSL) have conducted a series of experiments[3] to understand how we decide, based on the voice, whether a speaker is honest and confident, or on the contrary dishonest and uncertain.
A new process for inserting synthetic gene circuits into host cells, developed by a team of bioengineers at Arizona State University, has broad implications for improving the effectiveness of a range of disease therapies.
Synthetic biology is an interdisciplinary research field that uses engineering principles to create biological components that don't exist in the natural world. These synthetic components mimic naturally evolved organisms, but are customized to fight disease, including cancer.
Washington, D.C.. -- The onset of the COVID-19 pandemic caused a sharp decline in living standards and rising food insecurity in developing countries across the globe, according to a new study by an international team of economists.
6 February: The IMbrave150 trial found median overall survival was 19.2 months in patients treated with atezo+bev vs 13.4 months for those treated with sorafenib alone, the current standard treatment (HR, 0.66 [95% CI, 0.52-0.85]; P=0.0009). Survival at 18 months was 52% with atezo+bev and 40% in patients treated with sorafenib.
Berkeley -- The onset of the COVID-19 pandemic last year led to a devastating loss of jobs and income across the global south, threatening hundreds of millions of people with hunger and lost savings and raising an array of risks for children, according to new research co-authored at the University of California, Berkeley.
