Ecology -- Better mercury predictions
Johns Hopkins researchers have invented a new class of cancer immunotherapy drugs that are more effective at harnessing the power of the immune system to fight cancer.
New data released by the American Society of Plastic Surgeons (ASPS) shows continued growth in cosmetic procedures over the last year. According to the annual plastic surgery procedural statistics, there were 17.5 million surgical and minimally-invasive cosmetic procedures performed in the United States in 2017, a 2 percent increase over 2016.
The statistics also reveal Americans are turning to new and innovative ways to shape their bodies, as minimally-invasive cosmetic procedures have increased nearly 200% since 2000.
PULLMAN, Wash. - A Washington State University research team is solving a high-tech waste problem while addressing the environmental challenge of stormwater run-off.
The researchers have shown they can greatly strengthen permeable pavements by adding waste carbon fiber composite material. Their recycling method, described in the March issue of the Journal of Materials in Civil Engineering, doesn't require using much energy or chemicals -- a critical factor for recycling waste materials.
Traditional vs. pervious
A new understanding of why synthetic 2-D materials often perform orders of magnitude worse than predicted was reached by teams of researchers led by Penn State. They searched for ways to improve these materials' performance in future electronics, photonics, and memory storage applications.
DETROIT - Dutch adventurer Wim Hof is known as "The Iceman" for good reason. Hof established several world records for prolonged resistance to cold exposure, an ability he attributes to a self-developed set of techniques of breathing and meditation -- known as the Wim Hof Method -- that have been covered by the BBC, CNN, National Geographic and other global media outlets. Yet, how his brain responds during cold exposure and what brain mechanisms may endow him with this resistance have not been studied -- until now.
A theoretical framework explaining the risk of rare events causing major disruptions in complex networks, such as a blackout in a power grid, has been proposed by a mathematician at Queen Mary University of London.
Rare events can abruptly dismantle a network with much more severe consequences than usual and understanding their probability is essential in reducing the chances of them happening.
Every complex human tool, from the first spear to latest smartphone, has contained multiple materials wedged, tied, screwed, glued or soldered together. But the next generation of tools, from autonomous squishy robots to flexible wearables, will be soft. Combining multiple soft materials into a complex machine requires an entirely new toolbox -- after all, there's no such thing as a soft screw.
Once in orbit after it launches this fall, NASA's ICESat-2 satellite will travel at speeds faster than 15,000 miles per hour. Last week, the satellite's instrument began its journey toward space riding a truck from Maryland to Arizona, never exceeding 65 mph.
A team of astronomers led by Prof. Judd Bowman of Arizona State University unexpectedly stumbled upon "dark matter," the most mysterious building block of outer space, while attempting to detect the earliest stars in the universe through radio wave signals, according to a study published this week in Nature.
MORRIS, MINNESOTA - Omega-6 and omega-3 fatty acids are essential human nutrients, yet consuming too much omega-6 and too little omega-3 can increase the risk of cardiovascular disease, obesity, and diabetes. Today, Americans consume 10 to 15 grams of omega-6 for every gram of omega-3.
Previous studies have shown that consuming organic beef or organic dairy products lowers dietary intakes of omega-6, while increasing intakes of omega-3 and conjugated linoleic acid (CLA), another valuable, heart-healthy fatty acid.
Drones are changing the face of turtle research and conservation, a new study shows.
By providing new ways to track turtles over large areas and in hard-to-reach locations, the drones have quickly become a key resource for scientists.
The research, led by the University of Exeter, also says stunning drone footage can boost public interest and involvement in turtle conservation.
Not only the number of migrating cancer cells determines the risk for metastasis but also their characteristics, scientists from the German Cancer Research Center (DKFZ) have now reported in Nature Communications. For circulating cancer cells to be able to invade tissues and settle at other sites in the body, they have to exhibit a specific polarity. This discovery might in future help to better predict individual risk for metastasis and find appropriate therapies that can reduce it.
Vanderbilt University Medical Center is encouraging its medical providers to stop using saline as intravenous fluid therapy for most patients, a change provoked by two companion landmark studies released today that are anticipated to improve survival and decrease kidney complications.
Saline, used in medicine for more than a century, contains high concentrations of sodium chloride, which is similar to table salt. Vanderbilt researchers found that patients do better if, instead, they are given balanced fluids that closely resemble the liquid part of blood.
ANN ARBOR -- Our bodies are not just passively growing older.
Cells and tissues continuously use information from our environments--and from each other -- to actively coordinate the aging process. A new study from the University of Michigan Life Sciences Institute now reveals how some of that cross-talk between tissues occurs in a common model organism.
