Scientists from the University of Michigan have developed an innovative way to use NASA satellite data to track the movement of tiny pieces of plastic in the ocean. Microplastics form when plastic trash in the ocean breaks down from the sun's rays and the motion of ocean waves. These small flecks of plastic are harmful to marine organisms and ecosystems. Microplastics can be carried hundreds or thousands of miles away from the source by ocean currents, making it difficult to track and remove them. Currently, the main source of information about the location ...

Toronto, ON - Despite research showing associations between anabolic steroid use and criminal offending, the possibility of a similar association between legal performance-enhancing substance use, such as creatine, and criminal offending remained unknown. A new study published online in the journal Drug and Alcohol Dependence now shows that both forms of performance-enhancing substance use is longitudinally associated with criminal offending among U.S. adults. The study, which analyzed a sample of over 9,000 U.S. participants from the National Longitudinal Study ...

Liza Makowski, PhD, professor in the Department of Medicine and the UTHSC Center for Cancer Research, has long been interested in how the immune system is altered by obesity and how this impacts cancer risk and treatment. "Obesity is complex, because it can cause both inflammation and activate counter-inflammation pathways leading to immunosuppression," Dr. Makowski said. "How obesity impacts cancer treatments is understudied." Obese patients with breast cancer often have worse outcomes than non-obese patients. However, exciting developments are being made in other cancers that may also hold promise for treating breast cancer. In studies of ...

"Fit for 55": under this heading, the EU Commission will specify the implementation of the European Green Deal on 14 July. This refers to the more ambitious climate policy announced, with 55 instead of 40 percent emission reduction by 2030 (relative to 1990), and net-zero emissions in 2050. Coordination between the 27 EU states is expected to be difficult since unanimity is usually required here for sweeping changes. An economic model study by the Berlin-based climate research institute MCC (Mercator Research Institute on Global Commons and Climate Change) and the Potsdam Institute for Climate Impact Research (PIK) examines how to achieve good results under such conditions. The study has just been published in the renowned Journal of Environmental ...

New SARS-CoV-2 variants are spreading rapidly, and there are fears that current COVID-19 vaccines won't protect against them. The latest in a series of structural studies of the SARS-CoV-2 variants' "spike" protein, led by Bing Chen, PhD, at Boston Children's Hospital, reveals new properties of the Alpha (formerly U.K.) and Beta (formerly South Africa) variants. Of note, it suggests that current vaccines may be less effective against the Beta variant. Spike proteins, on the surface of SARS CoV-2, are what enable the virus to attach to and enter our cells, and all current vaccines are directed against them. The new study, published in Science on June 24, used cryo-electron microscopy (cryo-EM) ...

LA JOLLA, CA--Researchers at La Jolla Institute for Immunology (LJI) have shed light on a process in immune cells that may explain why some people develop cardiovascular diseases. Their research, published recently in Genome Biology, shows the key role that TET enzymes play in keeping immune cells on a healthy track as they mature. The scientists found that other enzymes do play a role in this process--but TET enzymes do the heavy lifting. "If we can figure out what's going on with these enzymes, that could be important for controlling cardiovascular disease," ...

Scientists at Tokyo Institute of Technology design polymers infused with a stress-sensitive molecular unit that respond to external forces by switching on their fluorescence. The researchers demonstrate the fluorescence to be dependent on the magnitude of force and show that it is possible to detect both, reversible and irreversible polymer deformations, opening the door to the exploration of new force regimes in polymers. Besides causing physical motion, mechanical forces can drive chemical changes in controlled and productive ways, allowing for desirable material properties. One way to go about this is by introducing a so-called mechanophore ...

Amphiphilic molecules, which aggregate and encapsulate molecules in water, find use in several fields of chemistry. The simple, additive-free connection of hydrophilic and hydrophobic molecules would be an efficient method for amphiphilic molecule synthesis. However, such connections, or bonds, are often fragile in water. Now, scientists at Tokyo Institute of Technology have developed an easy way to prepare water-stable amphiphiles by simple mixing. Their new catalyst- and reagent-free method will help create further functional materials. Soaps and detergents are used to clean things like clothes and dishes. But how do they actually work? It turns out that they are made of long molecules ...

A study from UCLA neurologists challenges the idea that the brain recruits existing neurons to take over for those that are lost from stroke. It shows that in mice, undamaged neurons do not change their function after a stroke to compensate for damaged ones. A stroke occurs when the blood supply to a certain part of the brain is interrupted, such as by a blood clot. Brain cells in that area become damaged and can no longer function. A person who is having a stroke may temporarily lose the ability to speak, walk, or move their arms. Few patients recover fully and most are left with some disability, but the majority exhibit some degree of spontaneous recovery during the first few weeks after the stroke. Doctors and scientists don't fully ...

A near-perfectly preserved ancient human fossil known as the Harbin cranium sits in the Geoscience Museum in Hebei GEO University. The largest of known Homo skulls, scientists now say this skull represents a newly discovered human species named Homo longi or "Dragon Man." Their findings, appearing in three papers publishing June 25 in the journal The Innovation, suggest that the Homo longi lineage may be our closest relatives--and has the potential to reshape our understanding of human evolution. "The Harbin fossil is one of the most complete human cranial fossils in the world," says author Qiang Ji, a professor of paleontology of Hebei GEO University. "This fossil preserved many ...

WASHINGTON--Antacids improved blood sugar control in people with diabetes but had no effect on reducing the risk of diabetes in the general population, according to a new meta-analysis published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism. Type 2 diabetes is a global public health concern affecting almost 10 percent of people worldwide. Doctors may prescribe diet and lifestyle changes, diabetes medications, or insulin to help people with diabetes better manage their blood sugar, but recent data points to common over the counter ...

CHAPEL HILL, NC - When we think of the brain, we think of neurons. But much of the brain is made of non-neuronal cells called glial cells, which help regulate brain development and function. For the first, time UNC School of Medicine scientist Katie Baldwin, PhD, and colleagues revealed a central role of the glial protein hepaCAM in building the brain and affecting brain function early in life. The findings, published in Neuron, have implications for better understanding disorders, such as autism, epilepsy, and schizophrenia, and potentially for creating therapeutics for conditions such as the progressive brain disorder megalencephalic ...

TAMPA, Fla. -- E-cigarettes spark many concerns, especially when it comes to youth vaping. However, emerging evidence suggests that e-cigarettes can be a helpful tool in smoking cessation. Researchers in Moffitt Cancer Center's Tobacco Research and Intervention Program wanted to build upon this evidence by testing whether they could help dual users, people who use both combustible cigarettes and e-cigarettes, quit smoking. In a new article published in The Lancet Public Health, they report results from a first-of-its kind nationwide study evaluating a targeted intervention aimed at transforming dual users' e-cigarettes from a product that might ...

CHAPEL HILL, NC - Developing a viable vaccine against dengue virus has proved difficult because the pathogen is actually four different virus types, or serotypes. Unless a vaccine protects against all four, a vaccine can wind up doing more harm than good. To help vaccine developers overcome this hurdle, the UNC School of Medicine lab of Aravinda de Silva, PhD, professor in the UNC Department of Microbiology and Immunology, investigated samples from children enrolled in a dengue vaccine trial to identify the specific kinds of antibody responses that correlate with ...

UPTON, NY--Scientists have organized proteins--nature's most versatile building blocks--in desired 2-D and 3-D ordered arrays while maintaining their structural stability and biological activity. They built these designer functional protein arrays by using DNA as a programmable construction material. The team--representing the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, Columbia University, DOE's Lawrence Berkeley National Laboratory, and City University of New York (CUNY)--described their approach in the June 17 issue of Nature Communications. "For decades, scientists have dreamed about rationally assembling proteins into specific organizations with preserved protein function," ...

Scientists from within the Antibody and Vaccine Group at the University of Southampton have gained novel insights into how an important class of immune receptors called tumour necrosis factor receptors (TNFR) are activated. The work, published in the journal Communications Biology, investigates a class of receptors present on immune cells called TNFR. These receptors, such as CD40, 4-1BB and OX40, are key in helping the immune system fight pathogens and cancer cells. Accordingly, antibody drugs which are designed to specifically target and activate these receptors (called ...

People with dementia receiving home health care visits are less likely to be readmitted to the hospital when there is consistency in nursing staff, according to a new study by researchers at NYU Rory Meyers College of Nursing. The findings are published in the journal Medical Care, a journal of the American Public Health Association. Home health care--in which health providers, primarily nurses, visit patients' homes to deliver care--has become a leading source of home- and community-based services caring for people living with dementia. These individuals often have multiple chronic conditions, take several medications, and need assistance with activities of daily living. In 2018, more than 5 million Medicare beneficiaries received ...

COLUMBUS, Ohio - Although the United States is the only wealthy nation that doesn't guarantee paid leave to mothers or fathers after the arrival of a new child, Americans endorse providing paid time off for parents nearly as much as people from other countries. About 82% of Americans support paid maternity leave, just slightly less than the 86% who support it in 26 wealthy nations, a new study shows. Where Americans differ from the rest of the world is that they are less supportive of government funding for paid leaves, prefer shorter leave times and are less supportive of paid leave for fathers. "We find marked differences in how Americans want paid leave administered compared ...
