Researchers report that CRISPR-Cas9 gene-editing technology can introduce hundreds of unintended mutations into the genome.
Scientists at The Scripps Research Institute (TSRI) have given new superpowers to a lifesaving antibiotic called vancomycin, an advance that could eliminate the threat of antibiotic-resistant infections for years to come.
The quest to develop a cure for HIV has long been plagued by a seemingly simple question: how do doctors determine if someone is cured? The virus has a knack for lying dormant in immune cells at levels undetectable to all but the most expensive and time-consuming tests. Pitt Public Health scientists have created a test sensitive enough to detect 'hidden' HIV, and yet is faster, less labor-intensive and less expensive than the current 'gold standard' test.
A large new study based on Medicaid data identifies a clear trend of people staying on their HIV medications longer than they used to.
New research from the University of Cincinnati reveals that residents of the mid-Ohio River Valley had higher than normal levels of perfluorooctanoic acid (PFOA) based on serum samples collected over a 22-year span. The exposure source was likely from drinking water contaminated by industrial discharges upriver. This is the first study of PFOA serum concentrations in US residents in the 1990s.
Scientists at The Scripps Research Institute (TSRI) have made another important advance in HIV vaccine design.
A new study published by Penn Medicine researchers this month and featured on the cover of the Journal of Neuroscience may help resolve this puzzle, revealing that while volume indeed decreases from childhood to young adulthood, gray matter density actually increases.
UC San Diego study of US data suggests a sleep-deprived planet by century's end. Researchers show that unusually warm nights can harm human sleep and that the poor and elderly are most affected. Rising temperatures will make sleep loss more severe.
New license-free tools will allow researchers to estimate the size of DNA fragments for a fraction of the cost of currently available methods. The tools, called a DNA ladders, can gauge DNA fragments ranging from about 50 to 5,000 base pairs in length.
In a new study, scientists at the University of Texas at Dallas have found that some types of cancers have more of a sweet tooth than others. 'It has been suspected that many cancer cells are heavily dependent on sugar as their energy supply, but it turns out that one specific type -- squamous cell carcinoma -- is remarkably more dependent,' said Dr. Jung-whan 'Jay' Kim, senior author of the study.
