Researchers have successfully used a DNA-editing technique to extend the lifespan of mice with the genetic variation associated with progeria, a rare genetic disease that causes extreme premature aging in children and can significantly shorten their life expectancy. The study was published in the journal Nature, and was a collaboration between the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health; Broad Institute of Harvard and MIT, Boston; and the Vanderbilt University Medical Center, Nashville, Tennessee.?
A new class of protein material that interacts with living cells without being absorbed by them can influence cell signaling, a new study shows. The material does this by binding and sequestering cell surface receptors.
The discovery could have far-reaching implications for stem cell research and enable the development of new materials designed to modulate the behavior of living systems.
The westerlies--or westerly winds--play an important role in weather and climate both locally and on a global scale, by influencing precipitation patterns, impacting ocean circulation and steering tropical cyclones. So, finding a way to assess how they will change as the climate warms is crucial.
What The Study Did: The findings of this survey study suggest that simply providing maps with COVID-19 case information wasn't necessarily associated with improved public knowledge, risk perception or reported intent to adhere to health guidelines.
Authors: Angela Fagerlin, Ph.D., of the University of Utah in Salt Lake City, is the corresponding author.

In the UK, men from ethnic minorities and women may have experienced worse mental health declines than White British men, according to a study published January 6, 2021 in the open access journal PLOS ONE by Eugenio Proto and Climent Quintana-Domeque of institutions including the University of Glasgow and the University of Exeter, UK.
CAR T cells are a breakthrough class of effective but often toxic cancer therapies
To prevent overactivation, switchable CAR T cells were engineered that can be turned on and off with an approved, widely used cancer drug
BOSTON - Scientists at Dana-Farber Cancer Institute and Mass General Cancer Center have created molecular ON-OFF switches to regulate the activity of CAR T cells, a potent form of cell-based immunotherapy that has had dramatic success in treating some advanced cancers, but which pose a significant risk of toxic side effects.
Amsterdam, NL, January 6, 2021 - There is growing evidence to support the hypothesis that there is a neurodevelopmental component to the late-onset neurodegeneration occurring in the brain of huntingtin gene (HTT gene) mutation carriers, and that this increased susceptibility to brain cell death begins during childhood.
A survey of approximately 5,000 Americans suggests that 31.1 percent of the U.S. public does not intend to get the COVID-19 vaccine once it becomes available to them - and the likelihood of vaccine refusal is highest among Black Americans, women and conservatives.
Philadelphia, January 6, 2021 - A multidisciplinary team of researchers led by Children's Hospital of Philadelphia (CHOP) has discovered several genetic markers associated with bone mineral accrual, which could ultimately help identify causes of eventual osteoporosis earlier in life through genetic testing. The findings, which were made possible by following a group of children over several years, were published online by the journal Genome Biology.
All athletes want to be at the top of their game when they compete, but some resort to nefarious approaches to achieve peak muscle growth, speed and agility. Recent developments in gene editing technology could tempt athletes to change their DNA to get an edge. Now, researchers reporting in ACS' Analytical Chemistry demonstrate first steps toward detecting this type of doping both in human plasma and in live mice.
Conductive ink is a great tool for printing flexible electronic circuits on surfaces. But these inks can be costly, they do not work on some materials, and devices to apply them can plug up. Now, scientists report in ACS Applied Electronic Materials that they have developed inexpensive conductive inks for clog-free ballpoint pens that can allow users to "write" circuits almost anywhere -- even on human skin.
Using copper foil, glass containers and a conventional household microwave oven, University of Wyoming researchers have demonstrated that pulverized coal powder can be converted into higher-value nano-graphite.
The discovery is another step forward in the effort to find alternative uses for Wyoming's Powder River Basin coal, at a time when demand for coal to generate electricity is declining due to concerns about climate change.
Hoppy beers such as pale ales are becoming increasingly popular. One reason is their pleasant fruity aroma that partially stems from compounds called thiols. Brewers have been looking for an accurate way to track thiols in beer, but current methods typically are not sensitive enough or require use of potentially harmful substances. Now, researchers in ACS' Journal of Agricultural and Food Chemistry present an automated, solvent-less process to assess thiols at very low concentrations.
ITHACA, N.Y. - For more than seven years, a mysterious wasting disease has nearly killed off sea star populations around the world. Some of these species stand at the brink of extinction.
New Cornell University-led research suggests that starfish, victims of sea star wasting disease (SSWD), may actually be in respiratory distress - literally "drowning" in their own environment - as elevated microbial activity derived from nearby organic matter and warm ocean temperatures rob the creatures of their ability to breathe.
Young adults ages 18-24 years old in the U.S. say that porn is their most helpful source of information about how to have sex, according to a new study led by a Boston University School of Public Health (BUSPH) researcher published in the journal Archives of Sexual Behavior.
