Bacteria are survival artists: When they get nutrition, they multiply rapidly, albeit they can also survive periods of hunger. But, when they grow too quickly, their ability to survive is hampered, as studies by a research team at the Technical University of Munich (TUM) on E. coli bacteria show. The results could help increase the effectiveness of antibiotics.
Taking advantage of a total lunar eclipse, astronomers using NASA's Hubble Space Telescope have detected Earth's own brand of sunscreen - ozone - in our atmosphere. This method simulates how astronomers and astrobiology researchers will search for evidence of life beyond Earth by observing potential "biosignatures" on exoplanets (planets around other stars).
PROVIDENCE, R.I. [Brown University] -- Two federal environmental standards regulating lead hazards in homes and child care facilities have different maximum thresholds, a discrepancy putting more than 35,000 kids in the United States at increased risk of lead poisoning.
That's according to a new study led by a Brown University researcher as the U.S. Environmental Protection Agency (EPA) moves to revise protective standards for dust lead levels on floors and windowsills in buildings constructed before 1978.
The Barotse Floodplain in Zambia is one of Africa's largest wetlands, representing varied ecotypes and high biodiversity conservation value. However, the Lozi People who live in the region face an intense "hungry season" from November to January when accessibility to food is very limited. This means that year-round nutrition and food security are consistently top priorities.
(WASHINGTON, August 6, 2020) -- Today, ASH published new guidelines to help older adults with acute myeloid leukemia (AML) and their health care providers make critical care decisions, including if and how to proceed with cancer treatment and the need for blood transfusions for those in hospice care.
Consider it Earth's ultimate mirror selfie.
In a new study, a team led by astrophysicist Allison Youngblood at the University of Colorado Boulder set out to achieve something new in planetary photography: The group used the Hubble Space Telescope to try to view Earth as if it were an exoplanet--or a world orbiting a star many light years from our own.
It wasn't easy: To capture Earth as an alien world, the researchers had to use the moon as a giant mirror, recording sunlight that had passed through our planet's atmosphere, bounced off the lunar surface and come back.
Movie studios estimate that they lose billions of dollars to digital movie piracy. But a new marketing study from the University of Georgia finds that piracy can actually boost ticket sales in certain situations.
The reason: pirates talk.
Pirated movies circulated online after their theatrical release saw about 3% higher box office receipts because of the increase in word-of-mouth advertising, according to Neil Bendle, an associate professor of marketing at the Terry College of Business.
FAIRFAX, Va. -- Researchers demonstrated the success of a fully implantable wireless medical device called a stentrode brain-computer interface designed to improve functional independence in patients with severe paralysis. The abstract was presented today at the Society of NeuroInterventional Surgery's (SNIS) 17th Annual Meeting.
EAST LANSING, Mich. - How much of a treatment is mind over matter? It is well documented that people often feel better after taking a treatment without active ingredients simply because they believe it's real -- known as the placebo effect.
A team of researchers from Michigan State University, University of Michigan and Dartmouth College is the first to demonstrate that placebos reduce brain markers of emotional distress even when people know they are taking one.
FAIRFAX, Va. -- Two new studies indicate that racial disparities related to outcomes exist among stroke patients, including one study that specifically examines stroke patients with COVID-19. The abstracts were presented today at the Society of NeuroInterventional Surgery's (SNIS) 17th Annual Meeting.
JUPITER, FL--Scripps Research chemists Hans Renata, PhD, and Alexander Adibekian, PhD, have discovered a way to efficiently create a synthetic version of a valuable natural compound called cepafungin I, which has shown promise as an anti-cancer agent.
Korea Brain Research Institute (headed by Suh Pann-ghill) announced on July 24 the discovery that an increase in amyloid-beta in the brain alters cholesterol biosynthesis, which was found by Dr. Cheon Mookyung of KBRI through RNA-seq analysis data (omics) using AI.
* Omics: "Omics" combines the prefix omni-, meaning "all", and the suffix -ics, meaning "study". Omics refers to the study of important information related to vital phenomena such as the activities of proteins that make up the genetic materials of the human body.
PITTSBURGH, Aug. 6, 2020 - New research by neuroscientists at the University of Pittsburgh and University of California San Francisco (UCSF) revealed that a simple, earbud-like device developed at UCSF that imperceptibly stimulates a key nerve leading to the brain could significantly improve the wearer's ability to learn the sounds of a new language. This device may have wide-ranging applications for boosting other kinds of learning as well.
Scientists from Stanley Manne Children's Research Institute at Ann & Robert H. Lurie Children's Hospital of Chicago discovered that a set of genes with decreased expression in individuals with Down syndrome may lead to clinical abnormalities in this population, such as poor muscle development and heart valve problems. Impairment in these same genes may also protect people with Down syndrome from developing solid tumors. Their findings were published in Scientific Reports.
Tropical oceans and fisheries are threatened by climate change, generating impacts that will affect the sustainable development of both local economies and communities, and regions outside the tropics through 'telecoupling' of human-natural systems, such as seafood trade and distant-water fishing, says a scientific review from UBC and international researchers.
