Sophia Antipolis, France - 1 Sept 2020: Heart patients hospitalised with COVID-19 can safely continue taking angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs), according to the BRACE CORONA trial presented in a Hot Line session today at ESC Congress 2020.1
Scientists have developed a new theory as to how hearing loss may cause dementia and believe that tackling this sensory impairment early may help to prevent the disease.
Hearing loss has been shown to be linked to dementia in epidemiological studies and may be responsible for a tenth of the 47 million cases worldwide.
Now, published in the journal Neuron, a team at Newcastle University, UK, provide a new theory to explain how a disorder of the ear can lead to Alzheimer's disease - a concept never looked at before.
Astronomers have known for two decades that the expansion of the universe is accelerating, but the physics of this expansion remains a mystery. Now, a team of researchers at the University of Hawai'i at Mānoa have made a novel prediction--the dark energy responsible for this accelerating growth comes from a vast sea of compact objects spread throughout the voids between galaxies. This conclusion is part of a new study published in The Astrophysical Journal.
It is a well-known problem: too rarely do nature conservation initiatives, recommendations or strategies announced by politicians lead to people really changing their everyday behaviour. A German-Israeli research team led by the Helmholtz Centre for Environmental Research (UFZ) and the German Centre for Integrative Biodiversity Research (iDiv) has investigated the reasons for this.
CINCINNATI - Scientists studying neuronal energy metabolism found evidence that the loss of an important energy regulator called AMPK in neural stem cells or glial cells called astrocytes causes neuronal death in laboratory rodents. They also discovered that AMPK loss in neural stem cells or neurons causes spontaneous brain seizures in the animals.
Bethesda, MD (September 1, 2020) -- The American Gastroenterological Association (AGA) published new clinical guidelines outlining an evidence-based approach for the initial gastrointestinal evaluation of chronic iron deficiency anemia in asymptomatic patients. Iron deficiency anemia is extremely common worldwide, and a gastrointestinal cause should be considered in all patients without an obvious cause for their anemia.
Biological sex influences the effect of amyloid beta on alterations to tau protein characteristic to Alzheimer's disease, suggesting a role for estradiol in preventing the disease in women, report scientists in the Journal of Alzheimer's Disease
Even though recognised in the Mediterranean Sea, the Macropodia czernjawskii spider crab was ignored by scientists (even by its namesake Vladimir Czernyavsky) in the regional faunal accounts of the Black Sea for more than a century. At the same time, although other species of the genus have been listed as Black sea fauna, those listings are mostly wrong and occurred either due to historical circumstances or misidentifications.
ADELPHI, Md. -- A new, miniature, low-frequency antenna with enhanced bandwidth will enable robust networking among compact, mobile robots in complex environments.
In a collaborative effort between the U.S. Army Combat Capabilities Development Command's Army Research Laboratory and the University of Michigan, researchers developed a novel design approach that improves upon limitations of conventional antennas operating at low frequencies--demonstrating smaller antennas that maintain performance.
Misfiring brain cells that control key parts of the mouth and tongue may be creating swallowing difficulties in children with neurodevelopmental disorders, according to neuroscientists with Virginia Tech and George Washington University.
In research using a mouse model of a genetic childhood disorder known as DiGeorge syndrome, scientists found brain cells called motor neurons that directly control the tongue muscles were firing spontaneously, out of sync with the mechanisms that should control their activity.
New insight on how an enzyme ensures the correct growth of pollen tubes in flowering plants has been published today in the open-access journal eLife.
The study reveals an unexpected role of KATANIN in moderating the mechanical properties of the papilla cell wall in Arabidopsis thaliana (A. thaliana), thereby preventing disordered pollen tube growth and allowing the tube to find its correct path to the underlying female plant tissues. These findings suggest that KATANIN has likely played a major role in the success of flowering plants on earth more widely.
Population bottlenecks contribute to the accumulation of several harmful mutations that cause age-related illnesses in killifish - a finding that may help answer a key question about aging.
The study, published today in eLife, reveals why killifish accumulate harmful mutations that cause age-related conditions such as cancer or neurodegenerative diseases that shorten lifespan. This may help scientists better understand how lifespan evolves among populations and may lead to new insights on human aging.
COLUMBIA, SC - September 1, 2020 - The University of South Carolina (UofSC) College of Engineering and Computing will transform the manufacturing and simulation processes used in aircraft production through a $5.7 million NASA grant. The research team's atom to airframe to spaceframe approach will make urban air mobility possible by dramatically increasing the production rate of aircraft.
ITHACA, N.Y. - A new study in mice helps explain why gut microbiomes of breastfed infants can differ greatly from those of formula-fed infants.
The study, "Dietary Sphinganine Is Selectively Assimilated by Members of the Mammalian Gut Microbiome," was published in July in the Journal of Lipid Research.
NASA-NOAA's Suomi NPP satellite provided a nighttime view of the Atlantic Ocean hurricane season's latest tropical cyclone off the coast of North Carolina. Ocean swells from the depression are affecting coastal North Carolina today, Sept. 1.
Tropical Depression 15 formed by 5 p.m. EDT off the coast of North Carolina and showed organized convection (rising air that forms the thunderstorms that make up a tropical cyclone). The storm has been battling vertical wind shear since its formation, which has kept it from intensifying into a tropical storm.
