BIRMINGHAM, Ala. - Congestive heart failure is a terminal disease that affects nearly 6 million Americans. Yet its management is limited to symptomatic treatments because the causal mechanisms of congestive heart failure -- including its most common form, ischemic cardiomyopathy -- are not known. Ischemic cardiomyopathy is the result of restricted blood flow in coronary arteries, as occurs during a heart attack, which starves the heart muscle of oxygen.
HAMILTON, ON (Aug. 9, 2018) - New research shows that for the vast majority of individuals, sodium consumption does not increase health risks except for those who eat more than five grams a day, the equivalent of 2.5 teaspoons of salt.
Fewer than five per cent of individuals in developed countries exceed that level.
Employer expectations of work email monitoring during nonwork hours are detrimental to the health and well-being of not only employees but their family members as well.
William Becker, a Virginia Tech associate professor of management in the Pamplin College of Business, co-authored a new study, "Killing me softly: electronic communications monitoring and employee and significant-other well-being," showing that such expectations result in anxiety, which adversely affects the health of employees and their families.
Aug.10, 2018--More than 4 in 10 women with asthma may go on to develop chronic obstructive pulmonary disease (COPD), according to a study conducted in Ontario, Canada, and published online in the Annals of the American Thoracic Society.
SAN FRANCISCO, CA--August 9, 2018--Trillions of tiny microbes and bacteria live in your gut, each with their own set of genes. These gut microbes can have both beneficial and harmful effects on your health, from protecting you against inflammation to causing life-threatening infections. To keep out pathogens yet encourage the growth of beneficial microbes, scientists have been trying to find ways to target specific microbial genes.
A one-two punch of powerful antibodies may be the best way to stop Ebola virus, reports an international team of scientists in the journal Cell. Their findings suggest new therapies should disable Ebola virus's infection machinery and spark the patient's immune system to call in reinforcements.
A technology designed to improve CRISPR-Cas9 gene editing in mosquitoes and other arthropods succeeds with a high degree of efficiency, while eliminating the need for difficult microinjection of genetic material, according to researchers.
The general public might think of the 21st century as an era of revolutionary technological platforms, such as smartphones or social media. But for many scientists, this century is the era of another type of platform: two-dimensional materials, and their unexpected secrets.
Why does the egg size of house sparrows vary so much? Isn't it always an advantage to be big?
Perhaps not surprisingly, baby sparrows that hatch from large eggs are consistently bigger their small egg counterparts. They can store up more reserves if food becomes scarce. So you would think that it's always a good idea to lay big eggs because your offspring would seem to have a greater chance of survival.
But what really set research biologists to wondering is that the difference in volume from the smallest to the largest egg can vary by 50 per cent.
LOGAN, UTAH, USA- Climate and land-use change are shrinking natural wildlife habitats around the world. Yet despite their importance to rural economies and natural ecosystems, remarkably little is known about the geographic distribution of most wild species - especially those that migrate seasonally over large areas. By combining NASA satellite imagery with wildlife surveys conducted by state natural resources agencies, a team of researchers at Utah State University and the University of Maryland, and the U.S.
