Research has identified critical factors that enable dangerous bacteria to spread disease by surviving on surfaces in hospitals and kitchens.
The study into the mechanisms which enable the opportunistic human pathogen Pseudomonas aeruginosa to survive on surfaces, could lead to new ways of targeting harmful bacteria.
EUGENE, Ore. -- April 22, 2021 -- Product marketers should be clear in their messaging to avoid customer skepticism that makes them feel duped, according to University of Oregon research.
At issue in a new study, published in the Journal of Business Research, was a social-cognitive construct called theory of mind, which considers how well people assess the mental states and apparent goals of others.
PROVIDENCE, R.I. [Brown University] -- As NASA's Perseverance rover begins its search for ancient life on the surface of Mars, a new study suggests that the Martian subsurface might be a good place to look for possible present-day life on the Red Planet.
Researchers have found that a natural molecule can effectively block the binding of a subset of human antibodies to SARS-CoV-2. The discovery may help explain why some COVID-19 patients can become severely ill despite having high levels of antibodies against the virus.
A new study by Simon Fraser University historical ecologists finds that Indigenous-managed forests--cared for as "forest gardens"--contain more biologically and functionally diverse species than surrounding conifer-dominated forests and create important habitat for animals and pollinators. The findings are published today in Ecology and Society.
In 2005, an ultramarathon runner ran continuously 560 kilometers (350 miles) in 80 hours, without sleeping or stopping. This distance was roughly 324,000 times the runner's body length. Yet this extreme feat pales in comparison to the relative distances that fruit flies can travel in a single flight, according to new research from Caltech.
SINGAPORE, 22 April 2021 - A multidisciplinary team of researchers from Duke-NUS Medical School and the Agency for Science, Technology and Research (A*STAR) in Singapore discovered a new mitochondrial peptide called MOCCI that plays an important role in regulating inflammation of blood vessel and immunity. The study, published in the journal Nature Communications, revealed how one gene encoded two molecules that provide two-pronged protection following viral infection.
Substantial proportions of pregnant and postpartum women scored high for symptoms of anxiety, depression, loneliness and post-traumatic stress in relation to COVID-19 in a survey carried out in May and June 2020, according to a new study published this week in the open-access journal PLOS ONE by Karestan Koenen and Archana Basu of Harvard T.H. Chan School of Public Health, US, and colleagues.
Time seems to pass more slowly in the UK COVID-19 lockdown - especially for people who are depressed, shielding or dissatisfied with social interactions
Kobe University Hospital's Dr. NISHIMORI Makoto and Project Assistant Professor KIUCHI Kunihiko et al. (of the Division of Cardiovascular Medicine, Department of Internal Medicine) have developed an AI that uses multiple kinds of test data to predict the location of surplus pathways in the heart called 'accessory pathways', which cause the heart to beat irregularly. In this study, the researchers were able to improve diagnosis accuracy by having the AI learn from two completely different types of test results- electrocardiography (ECG) data and X-ray images.
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers found a rotating baby galaxy 1/100th the size of the Milky Way at a time when the Universe was only seven percent of its present age. Thanks to assistance by the gravitational lens effect, the team was able to explore for the first time the nature of small and dark "normal galaxies" in the early Universe, representative of the main population of the first galaxies, which greatly advances our understanding of the initial phase of galaxy evolution.
When it comes to friendships and rivalries, male dolphins know who the good team players are. New findings, published in Nature Communications by University of Bristol researchers, reveal that male dolphins form a social concept of team membership based on cooperative investment in the team.
The week of Thanksgiving last year, a postcard arrived in mailboxes in Christiansburg. A link to a survey was on the back. On the front, there was a picture that was, by then, very familiar to the residents of a town that made history in 2019 as the first place in the U.S. to have a residential drone delivery service: a yellow-winged drone with a small cardboard box tucked underneath it.
Diseases continue to be a major threat to coral reef health. For example, a relatively recent outbreak termed stony coral tissue loss disease is an apparently infectious waterborne disease known to affect at least 20 stony coral species. First discovered in 2014 in Miami-Dade County, the disease has since spread throughout the majority of the Florida's Coral Reef and into multiple countries and territories in the Caribbean. Some reefs of the northern section of Florida's Coral Reef are experiencing as much as a 60 percent loss of living coral tissue area.
Stimulus-responsive supramolecular structures have emerged as an alternative to conventional ones, owing to their applications in sensing, drug delivery, and switchable memory systems. Now, scientists at Tokyo Institute of Technology explore the hydrostatic-pressure response of "foldamers"--artificial molecules that mimic protein folding--and report a shift in their preferred conformation with changing pressure, demonstrating hydrostatic pressure-enabled dynamic control. The finding opens doors to future development of pressure-sensitive foldamers and artificial materials.
