Researchers found that ribavirin increases the mutation rate of RNA viruses, pushing them into genetic meltdown and making them useless. This mechanism offers hope for designing more effective antiviral drugs.
Researchers have created filtration membranes with hydrophilic outer surfaces to resist fouling, increasing the amount of solution that can be passed through. The membranes also exhibit self-healing properties.
Researchers at U.S. Geological Survey and University of Denver have identified a new bird species, the Gunnison sage-grouse, through DNA analysis and genetic research. The study confirms the species' distinctiveness from the Greater sage-grouse and highlights concerns about its low genetic diversity and population decline.
Researchers found that calcium channel blockers (CCBs) were significantly less effective at preventing heart attacks, heart failure, and cardiovascular events compared to ACE inhibitors, beta-blockers, and diuretics. The study analyzed over 27,000 patients and showed a 26% higher risk of heart attack among CCB users.
A minor earthquake occurred in the Evansville area with a preliminary magnitude of 3.9, according to the USGS. This region has been identified as having a potential for damaging earthquakes.
Researchers propose a new understanding of granite formation, suggesting it occurs in rapid, dynamic events that take between 1,000 and 100,000 years. This challenges the long-held view of slow, multi-million year processes, and has significant implications for our understanding of crust formation and economic ore deposits.
Urban sprawl is expected to expand by 46% in coastal metropolitan regions by 2025, consuming 5.8 million acres of land, according to a study. The growth is driven by population increase and advances in transportation technology, which has allowed people to demand semi-rural locations with reasonable commute times.
Researchers at Rockefeller University have identified a crucial region of the hepatitis C virus protein NS5A, which plays an essential role in viral replication. This breakthrough discovery could accelerate the development of effective drugs and vaccines against HCV, a leading cause of liver disease.
Researchers found a specific protein, OX2, that controls inflammation in the brain. OX2 deficiency may lead to chronic brain inflammation, associated with Alzheimer's disease, multiple sclerosis, and AIDS-related dementia.
A Texas A&M University research team is counting Bowhead whales in the Okhotsk Sea to estimate their population size and understand the impact on the ecosystem. By using photo identification and genetic testing, researchers hope to gather information on the whales' feeding behavior and determine if their food supply is dwindling.
A USGS study links agricultural contaminants to declining amphibian populations in California's Sierra Nevada. Pesticides, such as chlorpyrifos and diazinon, were found to suppress enzyme activity in frogs, leading to population declines.
Researchers found a way to grow hepatitis C virus in labs, enabling genetic studies and potential vaccine development. The breakthrough could speed up progress against the disease, which affects 170 million worldwide.
Researchers at Vanderbilt University Medical Center have identified a new drug therapy that appears to be effective in reversing symptoms of Ménétrier's disease, a rare and premalignant stomach disorder. The treatment, which blocks activation of the EGF receptor, showed promising results in a patient with severe vomiting and protein loss.
