NEWTOWN SQUARE, Penn., Aug. 13, 2019 - In addition to cleaning the air and water, forests hold a tremendous amount of sequestered carbon. When trees die and then decay on the forest floor, that carbon is released into the atmosphere, a phenomenon that is one of the drivers of climate change. A first-of-its-kind study by a team that included the United States Department of Agriculture's Forest Service and Purdue University scientists finds that non-native invasive insects and diseases are reducing the amount of carbon stored in trees across the United States.
AUSTIN, Texas -- For adults with high blood pressure, greater blood pressure control than what's currently considered standard is associated with fewer adverse changes of the brain, which could mean lower risks of dementia and cognitive impairment, according to new research published in the Journal of the American Medical Association.
Researchers at the University of South Florida are harnessing the power of human physiology to transform greenhouse gases into usable chemical compounds - a method that could help lessen industrial dependence on petroleum and reduce our carbon footprint.
WASHINGTON, D.C., August 13, 2019 -- Advances in adapting the technology for cold climates and offshore use and better methods for predicting wind conditions have fanned significant growth of the use of wind turbines for electricity in the last 40 years. A new report takes stock of where the field is now and what lies ahead.
In a nationwide study, researchers used magnetic resonance imaging (MRI) to scan the brains of hundreds of participants in the National Institutes of Health's Systolic Blood Pressure Intervention Trial (SPRINT) and found that intensively controlling a person's blood pressure was more effective at slowing the accumulation of white matter lesions than standard treatment of high blood pressure.
WASHINGTON, D.C., August 13, 2019 -- Animal models provide benefits for biomedical research, but translating such findings to human physiology can be difficult. The human heart's energy needs and functions are difficult to reproduce in other animals, such as mice and rats. One new system looks to circumvent these issues and provide a functional view of how different treatments can help ailing cells in the heart following oxygen and nutrient deprivations.
Kidneys work to constantly filter blood and remove toxins from the body. Conditions such as chronic kidney disease (CKD) are characterized by a reduced ability to perform this essential function. CKD incidence is growing and more than 1.4 million individuals depend on dialysis or kidney transplant for survival. Development of new treatments requires an understanding of the mechanisms of the disease progression, but scientists have not been able to accurately model kidney filtration in vitro - until now.
Scientists at the National University of Science and Technology "MISIS" (NUST MISIS) have identified a new mechanism for removing magnetic nanoparticles through the kidneys, which will help to create more effective and safe drugs. The results of the study are published in the Journal of Controlled Release.
With the help of new technology, the researchers of the University of Turku in Finland have gained more detailed information on the diversity of the human lymphatic system than before. The research results can help to understand the human defence mechanisms on the molecular level even better than before. Several cancers, such as breast cancer and head and neck cancers, spread primarily via the lymphatic system.
The transfer of white blood cells between the lymphatic vessels, lymphoid organs, and blood circulation is the backbone of the human defence mechanism.
In 1935, the physicist Erwin Schrödinger put forward the thought experiment with the quantum cat, in which the cat is enclosed in a box together with a radioactive sample, a detector and a lethal amount of poison. If the radioactive material decays, the detector triggers an alarm and the poison is released. The special feature is that according to the rules of quantum mechanics, unlike everyday experience, it is not clear whether the cat is dead or alive. It would be both at the same time until an experimenter takes a look.
Scientists have developed an automated tool for mapping the movement of particles inside cells that may accelerate research in many fields, a new study in eLife reports.
The movements of tiny molecules, proteins and cellular components throughout the body play an important role in health and disease. For example, they contribute to brain development and the progression of some diseases. The new tool, built with cutting-edge machine learning technology, will make tracking these movements faster, easier and less prone to bias.
The summer heatwave of 2003 triggered a rockfall that shocked both researchers and the general public: 1,500 cubic metres of rock broke away from the Hoernli ridge - a volume roughly equivalent to two houses. The fracture event exposed bare ice on the surface of the steep scarp. Experts soon realised that the record temperatures had warmed the rock down to such a depth that the ice contained in its pores and fissures had melted. This effectively caused a sudden reduction of the bonding holding the rock mass together.
In the human body the salt content of cells and their surrounding is regulated by sophisticated transport systems. Special channels in the cell membrane selectively permit salt ions to flow in and out of cells. A research team led by Professor Thomas Jentsch at the FMP and MDC has now identified the molecular components of a previously unknown ion channel.
An international team of subsurface explorers from the University of Adelaide in Australia and the University of Aberdeen in Scotland have uncovered a previously undescribed 'Jurassic World' of around 100 ancient volcanoes buried deep within the Cooper-Eromanga Basins of central Australia.
PHILADELPHIA -A new large population-based study from the Sidney Kimmel Cancer Center - Jefferson Health shows that novel oral androgen signaling inhibitor therapies are associated with an increased risk of death in patients with pre-existing cardiovascular conditions. The research was published in the journal European Urology.
