Microplastic pollution discovered in St. Lawrence River sediments

Proteins are important building blocks in our cells and each cell contains millions of different protein molecules. They are involved in everything from structural to regulatory aspects in the cell. Proteins are constructed as linear molecules but they only become functional once they are folded into specific three-dimensional structures. Several factors, like mutations, stress and age, can interfere with this folding process and induce protein misfolding. Accumulated misfolded proteins are toxic and to prevent this, cells have developed quality control systems just like ...

(Millbrook, N.Y.) In the U.S., some 300,000 people are diagnosed with Lyme disease annually. Thousands also suffer from babesiosis and anaplasmosis, tick-borne ailments that can occur alone or as co-infections with Lyme disease. According to a new paper published in PLOS ONE, when small, fast-living mammals abound, so too does our risk of getting sick. In eastern and central North America, blacklegged ticks are the primary vectors for Lyme disease, babesiosis, and anaplasmosis. The pathogens that cause these illnesses are widespread in nature; ticks acquire them when ...

A common Asian spice and cancer-hampering molecules show promise in slowing the progression of mesothelioma, a cancer of the lung's lining often linked to asbestos. Scientists from Case Western Reserve University and the Georg-Speyer-Haus in Frankfurt, Germany, demonstrate that application of curcumin, a derivative of the spice turmeric, and cancer-inhibiting peptides increase levels of a protein inhibitor known to combat the progression of this cancer. Their findings appeared in the Aug. 14 online edition Clinical Cancer Research; the print version of the article will ...

For decades, researchers have tried to develop broadly effective vaccines to prevent the spread of illnesses such as HIV, malaria, and tuberculosis. While limited progress has been made along these lines, there are still no licensed vaccinations available that can protect most people from these devastating diseases. So what are immunologists to do when vaccines just aren't working? At Caltech, Nobel Laureate David Baltimore and his colleagues have approached the problem in a different way. Whereas vaccines introduce substances such as antigens into the body hoping ...

New Orleans, LA – Research led by Paulo Rodriguez, PhD, an assistant research professor of Microbiology, Immunology & Parasitology at LSU Health New Orleans' Stanley S. Scott Cancer Center, has identified the crucial role an inflammatory protein known as Chop plays in the body's ability to fight cancer. Results demonstrate, for the first time, that Chop regulates the activity and accumulation of cells that suppress the body's immune response against tumors. The LSU Health New Orleans research team showed that when they removed Chop, the T-cells of the immune system mounted ...

The NASA-NOAA Suomi NPP satellite saw the western edge of Tropical Storm Fung-Wong over the central Philippines on Sept. 18. Fung-Wong developed on Sept. 17 as Tropical Depression 16W, and strengthened into a tropical storm by 5 p.m. EDT on Sept. 17. When NASA-NOAA's Suomi NPP satellite passed over Tropical Storm Fung-Wong on Sept. 18 at 05:24 UTC and the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard captured a visible picture of the storm. The VIIRS instrument revealed that a thick band of powerful thunderstorms spiraled around the southwestern ...

A unique partnership to support private efforts to provide mental health services to veterans and their families could provide a model for similar efforts should federal officials decide to expand privately provided health care as part of reform of the VA health system, according to a new RAND Corporation report. The Welcome Back Veterans Initiative, a joint project of philanthropic groups and major academic medical centers, has provided an array of patient care, education and other services to veterans and their families. Backed by Major League Baseball and the Robert ...

CHAMPAIGN, Ill. — Even in a hyperconnected world where laptops, phones, tablets and now even wristwatches are tethered to the Internet 24/7, employers are still wary about the performance and social costs imposed by employees who work remotely. But a new study by a University of Illinois business professor says telecommuting yields positive effects for two important measures of employee performance, and it can even produce very strong positive effects under certain circumstances for some employees. According to Ravi S. Gajendran, a professor of business administration ...

MADISON, Wis. – The link between a protein typically associated with Alzheimer's disease and its impact on memory and cognition may not be as clear as once thought, according to a new study from the University of Wisconsin-Madison's Waisman Center. The findings are revealing more information about the earliest stages of the neurodegenerative disease. The researchers — including lead study author Sigan Hartley, UW-Madison assistant professor of human development and family studies, and Brad Christian, UW-Madison associate professor of medical physics and psychiatry and ...

A group of international scientists have developed a new method to study Ebola virus in wildlife. Video link here. The Wildlife Conservation Society (WCS)-led research, published today in the journal PLOS Neglected Tropical Diseases, describes the use of fecal samples from wild great apes to identify populations likely to have been exposed to the virus. This represents a new tool for performing large, population-scale field assessments that can potentially change the way Ebola virus is studied and improve our understanding of the virus' distribution in space and time—a ...
