Philadelphia, March 1, 2018 - Marijuana is the most commonly used illicit drug in the United States, with an increasing trend of use among middle-aged and older individuals. However, potential health effects of marijuana use in the general population have not been extensively studied, and little is known about potential effects on kidney function.
San Francisco, CA -- March 1, 2018 -- Some organisms have a remarkable capacity for regenerating tissue. If a fish or salamander suffers heart damage, for instance, their cells are able to divide and successfully repair the injured organ. Imagine if you could do the same.
In the embryo, human heart cells can divide and multiply, allowing the heart to grow and develop. The problem is that, right after birth, cardiomyocytes (heart muscle cells) lose their ability to divide. The same is true for many other human cells, including those of the brain, spinal cord, and pancreas.
JUPITER, FL - March 1, 2018 - Scientists on the Florida campus of The Scripps Research Institute (TSRI) have discovered a new target for treating major depressive disorder, a disease that affects more than 16 million American adults. Their research shows that individuals with high levels of an enigmatic receptor called GPR158 may be more susceptible to depression following chronic stress.
WASHINGTON, DC (March 1, 2018)--A new report published today in the Journal of Adolescent Health says that the recent changes in U.S. immigration policy have triggered serious psychological distress for many Latino parents, including those living in the United States legally.
Jumping robot spiders and swarms of robotic bees sounds like the stuff of science fiction, but researchers at The University of Manchester are already working on such projects and aiming to lead the world in micro robotics.
New Haven, Conn. -- People with stage III colon cancer who regularly eat nuts are at significantly lower risk of cancer recurrence and mortality than those who don't, according to a new, large study led by researchers at Yale Cancer Center.
The findings were published today in the Journal of Clinical Oncology.
Using two different measurement methods, researchers from North Carolina State University conducted a two-year study of North Carolina's Jordan Lake in which they monitored toxic algal blooms. The researchers found that multiple cyanotoxins from toxic algal blooms are present year-round, albeit in very low concentrations. Their findings could improve the ability to predict toxic blooms.
February 28, 2018 - In patients undergoing reconstructive surgery of the face, treatment with botulinum toxin A (BTX-A, or 'Botox') can improve the final appearance of surgical scars, reports a clinical trial in the March issue of Plastic and Reconstructive Surgery®, the official medical journal of the A
Innate or acquired resistance to current standard-of-care therapies is a major hindrance to successful chemotherapeutic intervention. There is a critical need to elucidate the underlying mechanisms responsible for chemoresistance in order to accelerate the development of more efficacious treatment strategies.
Researchers have called for more evidence to understand the safety and effectiveness of video consultation, and its impact on patient access and GP workload.
The Asian tiger mosquito -- carrier of such diseases as dengue, yellow fever, Rift Valley fever, Chikungunya and Zika -- appears to have vanished from Palmyra.
CLEMSON, South Carolina - As a general rule of thumb, if there is a puzzling phenomenon occurring somewhere deep in outer space, a black hole is often the culprit behind it.
Using new data gathered from sites in southern Africa, University of Rochester researchers have extended their record of Earth's magnetic field back thousands of years to the first millennium.
The record provides historical context to help explain recent, ongoing changes in the magnetic field, most prominently in an area in the Southern Hemisphere known as the South Atlantic Anomaly.
Using lasers, U.S. and Austrian physicists have coaxed ultracold strontium atoms into complex structures unlike any previously seen in nature.
"I am amazed that we've discovered a new way that atoms assemble," said Rice University physicist Tom Killian. "It shows how rich the laws of physics and chemistry can be." Killian is the lead scientist on a new paper in Physical Review Letters (PRL) that summarized the group's experimental findings.
Cleveland, Ohio -- Roberto Fernández Galán, an assistant professor of electrical engineering and computer science at the university's School of Engineering, and a team of undergraduate researchers at Case Western Reserve have been recording the electrical activity of hundreds of neurons as they fire inside the brain of a mouse model-for up to half an hour at a time.
"Neurons are highly active spontaneously, so 30 minutes is actually a very long time," Galán said.
