The good news is that adolescent "sexting" is not at epidemic levels as reported in some media headlines. The bad news is that it also has not decreased despite preventive efforts by educators and others. Most commonly, the term sexting has been used to describe incidents where teenagers take nude or semi-nude photos or videos of themselves and exchange that content via text or private social media messages. While intended to be shared with trusted romantic partners, these images also can find their way into the hands of others.
Knee injuries can be a scourge to collegiate and pro athletes alike, but Penn State researchers say a single measurement taken by a clinician may help predict whether a person is at risk for knee instability.
The researchers found that measuring the distance between the tibial tubercle (TT) -- a bony bump on the tibia, commonly referred to as the shin, below the kneecap -- and the trochlear groove (TG), the joint in which the kneecap sits, using magnetic resonance imaging (MRI) was a reliable, precise and accurate diagnostic of problems with the kneecap moving out of its joint.
MISSOULA - At first glance, there aren't many similarities between westslope cutthroat trout in Montana, wolves on Isle Royale National Park in Michigan and Australia's mountain pygmy possum, a mouse-sized alpine marsupial.
With all three, though, managers have attempted or explored the possibility of genetic rescue, a conservation approach that involves moving a small number of individual animals from one population to another to reduce genetic problems and decrease extinction risk.
Bacteria do not simply perish in hunger phases fortuitously; rather, the surrounding cells have a say as well. A research team from the Technical University of Munich (TUM) has now discovered that two factors, above all, decide over life and death: the energy required to continue living and the efficiency with which surviving cells can recycle biomass from dead cells.
BOSTON - In metastasis, cancer cells break away from the original tumor and take root in another region of the body by entering the blood stream. In order to spread, metastatic cells cross over the endothelium - a barrier of endothelial cells lining the circulatory system that controls the passing of materials into and out of the blood stream - a behavior not as easily accomplished by non-metastatic cells.
EAST LANSING, Mich. - Michigan State University researchers have found that many stroke patients feel unprepared when discharged from the hospital. Their caregivers feel the same.
But when a home-based support network using social work case managers and online resources is put into place, quality of life and confidence in managing one's health improve, according to a new study published in the American Heart Association's journal Circulation: Cardiovascular Quality and Outcomes.
It’s a case of grand larceny that could lead to new fuels and cleanup chemicals. Ten species of red algae stole about 1 percent of their genes from bacteria to cope with toxic metals and salt stress in hot springs, according to a study in the journal eLife.
Researchers at Boston Children's Hospital report creating the first human tissue model of an inherited heart arrhythmia, replicating two patients' abnormal heart rhythms in a dish, and then suppressing the arrhythmia with gene therapy in a mouse model. Their work, published in two papers in the July 30 print issue of the journal Circulation, opens the possibility of developing single-dose gene therapy treatments for inherited arrhythmias, and perhaps more common arrhythmias such as atrial fibrillation.
More "intensive" beekeeping does not raise the risk of diseases that harm or kill the insects, new research suggests.
Intensive agriculture - where animals or plants are kept crowded together in very high densities - is thought to result in higher rates of disease spreading.
But researchers from the University of Exeter and the University of California, Berkeley found this is not the case for honeybees.
Giving credence to the saying, "While the cat's away, the mice will play," a new study indicates that pumas and medium-sized carnivores lie low when they sense the presence of humans, which frees up the landscape for rodents to forage more brazenly.
PITTSBURGH--Carnegie Mellon University's Assistant Professor of Electrical and Computer Engineering (ECE) Maysam Chamanzar and ECE Ph.D. student Matteo Giuseppe Scopelliti today published research that introduces a novel technique which uses ultrasound to noninvasively take optical images through a turbid medium such as biological tissue to image body's organs. This new method has the potential to eliminate the need for invasive visual exams using endoscopic cameras.
How you spend your money can signal aspects of your personality, according to research published in Psychological Science, a journal of the Association for Psychological Science. Analyses of over 2 million spending records from more than 2,000 individuals indicate that when people spend money in certain categories, this can be used to infer certain personality traits, such as how materialistic they are or how much self-control they tend to have.
In recent years, Latinos have migrated from Central America to the United States due to violence, high crime rates, and poverty in their home countries. However, violence and trauma continue along their way to the United States. New research led by George Mason University's College of Health and Human Services (CHHS) found that undocumented Latina immigrants meet the threshold for post-traumatic stress disorder (PTSD) diagnosis at nearly four times (34%) the rate of civilian women in America overall (9.7%).
COLUMBUS, Ohio - Sorry, marijuana moms and dads: Using pot may not make you a more relaxed parent, at least when it comes to how you discipline your children.
A study of California parents found that current marijuana users administered more discipline techniques of all kinds to their children on average than did non-users. That includes everything from timeouts to, in some cases, physical abuse.
As the Apollo 11 Lunar Module approached the Moon's surface for the first manned landing, commander Neil Armstrong switched off the autopilot and flew the spacecraft manuallly to a landing.
A new video, created at Arizona State University's School of Earth and Space Exploration, shows what Armstrong saw out his window as the lander descended -- and you'll see for yourself why he took over control.
