(Jena, Germany) Photopharmacology investigates the use of light to switch the effect of drugs on and off. Now, for the first time, scientific teams from Jena, Munich, and New York have succeeded in using this method to control a component of cells that was previously considered inaccessible.
Present everywhere and now selectively controllable
A low-pressure area designated as System 90L appears to be developing in the Straits of Florida, located between Southern Florida and Cuba. NASA's Aqua satellite measured cloud top temperatures within the developing system and found some stronger storms.
At 8:50 a.m. EDT on May 15, NOAA's National Hurricane Center (NHC) issued a Special Tropical Weather Outlook issued to discuss the potential for tropical or subtropical development near the northwest Bahamas.
In designing electronic devices, scientists look for ways to manipulate and control three basic properties of electrons: their charge; their spin states, which give rise to magnetism; and the shapes of the fuzzy clouds they form around the nuclei of atoms, which are known as orbitals.
CHICAGO (May 15, 2020): When researchers from the University of Colorado Anschutz Medical Campus, Aurora, used a combination of two specific blood-clotting tests, they found critically ill patients infected with Coronavirus Disease 2019 (COVID-19) who were at high risk for developing renal failure, venous blood clots, and other complications associated with blood clots, such as stroke.
Grasslands across the globe, which support the majority of the world's grazing animals, have been transitioning to shrublands in a process that scientists call "woody plant encroachment."
Managed grazing of drylands is the most extensive form of land use on the planet, which has led to widespread efforts to reverse this trend and restore grass cover due to the belief that it results in less water entering streams and groundwater aquifers.
RIVERSIDE, Calif. -- An international research team led by scientists at the University of California, Riverside, has observed light emission from a new type of transition between electronic valleys, known as intervalley transmissions.
The research provides a new way to read out valley information, potentially leading to new types of devices.
After Tropical Cyclone Vongfong made landfall in the Philippines early on May 14 and began tracking through the country, imagery from NASA-NOAA's Suomi NPP satellite showed the storm was weakening.
On May 14, 2020, Typhoon Vongfong became the first typhoon of the 2020 West Pacific season. It came ashore as a typhoon and by May 15, it had weakened to a tropical storm.
Leesburg, VA, May 15, 2020--In an open-access article published ahead-of-print by the American Journal of Roentgenology (AJR), a team of Chinese radiologists discussed modifications to the CT examination process and strict disinfection of examination rooms, while outlining personal protection measures for radiographers during the coronavirus disease (COVID-19) outbreak.
WOODS HOLE, Mass. -- More carbon is stored in the forests, peatlands, and lakes of the high northern (boreal) latitudes than is currently in the atmosphere. Therefore, understanding how the boreal latitudes, which include Canada and Alaska, respond to global warming is very important for predicting its trajectory. As the climate warms, the air gets drier and can take up more water. The pines, spruces, and larches of boreal forests respond by largely retaining their water, but it hasn’t been known how boreal peatlands (bogs and fens) respond.
Salt Lake County, Utah’s air pollution varies over the year, and at times it is the worst in the United States. The geography traps winter inversions and summertime smog throughout the Salt Lake Valley, but underserved neighborhoods—and their schools—experience the highest concentrations. Previous research has shown pollution disparities using annual averages of PM 2.5 levels, the tiny breathable particles that can damage lungs just hours after exposure.
