Since light-emitting diodes only produce monochrome light, manufacturers use various additive colour-mixing processes to produce white light.
Researchers from the National University of Science and Technology "MISIS" developed a database that will help create new grades of steels. This will speed up the process of creating innovative steel grades with specified strength and ductility allow at least 10 times, which will allow manufacturing car bodies of the most complex shapes. Article on the research is published in "Calphad".
July 11, 2019 - Progress in the pharmaceutical industry depends largely on the achievements and advances in medicinal chemistry. Big pharma companies, which set the pace of the industry, can be regarded as major drivers of medicinal chemistry evolution. Since 2007 there has been a significant decline in the number of patent records involving new chemical entities, and many molecules observed during the HTS (High Throughput Screening) boom, were not considered attractive.
Yersinia have spread fear and terror, especially in the past, but today the plague pathogens have still not been completely eradicated. The bacteria inject various enzymes, including the enzyme YopO, into the macrophages of the immune system. There it is activated and prevents the defense cells from enclosing and digesting the plague bacteria. Using the latest methods, scientists from the Institute of Physical and Theoretical Chemistry at the University of Bonn have now deciphered how YopO changes its shape and thus contributes to confusing the immune system.
This clear, gooey substance, which is naturally produced by the human body, has been popularized by cosmetic and skin care products that promote healthier, plumper and more supple skin. Also recognized for its abilities to speed up wound healing, reduce joint pain from osteoarthritis, and relieve dry eye and discomfort, a neuroscientist at Florida Atlantic University's Brain Institute (I-BRAIN) and Schmidt College of Medicine, has discovered a novel mechanism and role in the brain for hyaluronic acid.
The mustards, broccolis and cabbages of the world share a distinct and bitter taste. Some consider the flavor of cruciferous plants their strongest attribute. But even in India and China, where Brassicas have been cultivated for more than 4,000 years, scientists have sought to tone down the chemical compounds responsible for their pungent flavor. Turns out the same compounds that make them bitter also make them toxic at some levels.
DeKalb, Ill. -- A new study led by Mitch Irwin and Karen Samonds of Northern Illinois University finds that degraded rainforest habitats are having an unhealthy impact on at least one species of Madagascar's treasured lemurs, the most endangered mammal group in the world.
As if black holes weren't mysterious enough, astronomers using NASA's Hubble Space Telescope have found an unexpected thin disk of material furiously whirling around a supermassive black hole at the heart of the magnificent spiral galaxy NGC 3147, located 130 million light-years away.
NASA's Aqua satellite passed over the Gulf of Mexico and took the temperature of Potential Tropical Cyclone 2 as it moved westward through the Gulf of Mexico. NASA found the very cold cloud tops indicating the storm had potential for dropping heavy rain.
Infrared light enables NASA to take the temperatures of clouds and thunderstorms that make up tropical cyclones. The stronger the storms are indicate that they extend high into the troposphere and have cold cloud top temperatures.
A research team headed by scientists at University of California San Diego School of Medicine and the Ludwig Institute for Cancer Research at UC San Diego has identified an enzyme involved in remodeling the plasma membrane of multiple cancer cell types that is critical to both survival of tumors and their uncontrolled growth.
The finding, published in the July 11, 2019 issue of Cell Metabolism, suggests a potential target for new drugs.
