The Yangtze Bank is a flat and broad shallow water, located at the junction of the Yellow Sea and the East China Sea. Large river discharge and strong wind- and tide-induced mixing created a large amount of land sediment discharge as well as the resuspension of bottom sediment, making the Yangtze Bank one of the most turbid coastal areas in the world (Figure 1). The high resolution distribution and tidal variation of suspended sediment over the Yangtze Bank have been revealed in a recent study.
Foraminifera, an ancient and ecologically highly successful group of marine organisms, are found on and below the seafloor. Geobiologists at Ludwig-Maximilians-Universitaet (LMU) in Munich report that several species not only survive, but thrive, in these oxygen-free sediments.
Some of the fastest video cameras ever developed have been used by KAUST researchers to clarify how molecular-scale changes to water surfaces may impact the performance of industrial-scale purifications.
One factor that influences the stability of emulsions is how quickly small bubbles or droplets join together into larger droplets. Ivan Vakarelski, a research scientist in Sigurdur Thoroddsen's lab, notes that this type of coalescence is driven by variables ranging from bubble size, collision speed, and the "freedom" of molecules located at liquid surfaces.
EAST LANSING, Mich. - You might think social media is addictive, but how do certain platforms measure against one another? Researchers from Michigan State University and California State University-Fullerton conducted the first study comparing problematic use between Facebook and Snapchat -- while also uncovering surprising findings about users' personality traits.
An international group of researchers have discovered that inhibiting AHR (aryl hydrocarbon receptor), a protein with roles in regulating immunity, stem cell maintenance and cellular differentiation, enables the immune system to combat replication of zika virus in the organism far more effectively. In experiments performed at the University of São Paulo’s Biomedical Sciences Institute (ICB-USP) in Brazil, the antiviral therapy proved capable of preventing the development of microcephaly and other malformations in mouse fetuses whose mothers were infected while pregnant.
UNIVERSITY PARK, Pa. -- In their zeal to promote the importance of climate change as an ecological driver, climate scientists increasingly are ignoring the profound role that indigenous peoples played in fire and vegetation dynamics, not only in the eastern United States but worldwide, according to a Penn State researcher.
FINDINGS
A UCLA-led study has found that dermatopathologists, who specialize in diagnosing skin diseases at the microscopic level, are motivated both by patient safety concerns and by malpractice fears -- often simultaneously -- when ordering multiple tests and obtaining second opinions, with a higher proportion of these doctors reporting patient safety as a concern.
A new relationship between humanity and the ocean is required to secure the continuity of the diverse life support roles provided by the sea, according to a paper published in Nature Communications on 17 July 2020.
Titled "A transition to sustainable ocean governance", it describes three key transition pathways that can make complex ocean systems more resilient and ensure a more sustainable future.
DALLAS, July 20, 2020 -- Nearly 60% of American children do not have healthy cardiorespiratory fitness (CRF), a key measure of physical fitness and overall health, according to "Cardiorespiratory Fitness in Youth - An Important Marker of Health," a new Scientific Statement from the American Heart Association, published today in the Association's flagship journal Circulation.
For the first time, a single, twisted nanoparticle has been accurately measured and characterised in a lab, taking scientists one vital step closer to a time when medicines will be produced and blended on a microscopic scale.
Michigan coyotes in most of the Lower Peninsula are the "top dogs" in the local food chain and can dine on a wide variety of small animals, including rabbits and rodents, along with berries and other plant foods, insects, human garbage and even outdoor pet food.
But in the Upper Peninsula, coyotes coexist with gray wolves and play a subordinate role in the food web. As a result, the diets of U.P. coyotes contain less meat than Lower Peninsula coyotes.
There floats an enormous plastic garbage island in the North Pacific that is seven times the size of the Korean Peninsula. The island, called the Great Pacific Garbage Patch, is the result of 13 million tons of plastic that flow into the ocean annually from the 20,000 units of plastic consumed per second around the world. Plastic takes decades to hundreds of years to decompose naturally with plastic bags taking 10 to 20 years, nylon products or disposable straws 30 to 40 years, and plastic water bottles - commonly used once then thrown away -500 years to decompose.
In a new study, published in Pediatrics, researchers have shown that being African American was strongly associated with a higher risk of postoperative complications and mortality among apparently healthy children. In fact, compared to their white peers, apparently healthy children who were African American were nearly 3.5 times more likely to die within 30 days after surgery.
New research indicates that mailing colorectal cancer screening kits to Medicaid enrollees is a cost-effective way to boost screening rates. The findings are published early online in CANCER, a peer-reviewed journal of the American Cancer Society (ACS).
Findings from the first international prostate cancer quality of life study conducted by patients themselves reports that significant numbers of men treated for the disease are struggling with continence and sexual problems after treatment. Results suggest that any treatment apart from active surveillance may negatively affect quality of life, and indicate that for many men these effects may be greater than previously thought.
