PITTSBURGH, July 19, 2018 - Postmenopausal factors may have an impact on the heart-protective qualities of high-density lipoproteins (HDL) - also known as 'good cholesterol' - according to a study led by researchers in the University of Pittsburgh Graduate School of Public Health.
NEW YORK, July 19, 2018 -- The nervous system is a complex organ that relies on a variety of biological players to ensure daily function of the human body. Myelin--a membrane produced by specialized glial cells--plays a critical role in protecting the fibers that help carry messages throughout the body. In the central nervous system (CNS), glial cells known as oligodendrocytes are responsible for producing myelin.
Cities can serve as useful proxies to study and predict the effects of climate change, according to a North Carolina State University research review that tracks urbanization's effects on plant and insect species.
Cities often display many of the predicted effects of climate change, including higher temperatures, higher carbon dioxide concentration and higher drought rates. Some of those effects are due to impermeable building materials like concrete and glass, which help create "urban heat islands" and prevent water from soaking into soil.
China's power systems operators must invest in renewable energy to meet climate commitments. Wind power and PV are the lowest cost renewables, but they only deliver power when it's windy or sunny.
By contrast, more expensive Concentrated Solar Power (CSP), which can store its solar energy relatively inexpensively, and for long durations, can deliver power at any time, day or night.
PHOENIX, Ariz. -- July 18, 2018 -- DNA methylation is a molecular process that helps enable our bodies to repair themselves, fight infection, get rid of environmental toxins, and even to think. But sometimes this process goes awry.
A team of scientists led by the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, has identified how DNA methylation is associated with a condition known as non-alcoholic fatty liver disease (NAFLD), which can lead to liver cirrhosis and death, and is one of the leading indicators for liver transplants.
A clinical trial of the use of adrenaline in cardiac arrests has found that its use results in less than 1% more people leaving hospital alive - but almost doubles the risk of severe brain damage for survivors of cardiac arrest. The research raises important questions about the future use of adrenaline in such cases and will necessitate debate amongst healthcare professionals, patients and the public.
The MUSE (Multi Unit Spectroscopic Explorer - https://www.eso.org/public/teles-instr/paranal-observatory/vlt/vlt-instr/muse/) instrument on ESO's Very Large Telescope (VLT - http://www.eso.org/public/teles-instr/paranal-observatory/vlt/ ) works with an adap
Antarctica is not as isolated from the rest of the world as scientists have thought, new research reveals, with potential for drifting plastics to create problems in the continent in future and new species to colonise there as the climate warms.
Even when people have well-connected social networks beyond their home cities and across state lines, they are still most frequently interacting with people who are very geographically near.
That is one of the major outcomes of an expansive, 16-month study of more than 51 million geo-tagged tweets generated by more than 1.7 million Twitter users across the U.S. The study was funded, in part, by the National Science Foundation.
In a new study published in the journal Peer J this week, researchers at UniSA's Body in Mind Research Group have found people suffering osteoarthritis in the knees reported reduced pain when exposed to visual illusions that altered the size of their knees.
UniSA researcher and NHMRC Career Development Fellow, Dr Tasha Stanton says the research combined visual illusions and touch, with participants reporting up to a 40 per cent decrease in pain when presented with an illusion of the knee and lower leg elongated.
