Researchers at the University of Illinois at Chicago and AbbVie Inc. have developed a novel device that will help scientists and pharmaceutical companies more effectively screen and test formation of drug substance - active pharmaceutical ingredient (API).
Whether at Oktoberfest, the movie theater or a shopping mall, the enticing aroma of soft pretzels is unmistakable. Now, researchers have identified the key compounds that give these twisted knots their distinctive scent. They report their results in ACS' Journal of Agricultural and Food Chemistry.
Students think it is instructors' responsibility to ensure they don't surf the web in class, according to a new study.
In a recent mixed-method study, researchers from the University of Waterloo surveyed 478 undergraduates and 36 instructors on their perception of technology use in class.
The survey found that nine per cent of students thought course materials that could be seen on other students' laptops were distracting, whereas 49 per cent thought that non-course materials on other students' screens were distracting.
Russian scientists found that nanocrystal tungsten trioxide can be used instead of barium for X-ray examinations and also in cancer treatment. The results of the study are published in «Journal of Nanomaterials».
Researchers at WMG at the University of Warwick have found that use of inductive charging, whilst highly convenient, risks depleting the life of mobile phones using typical LIBs (Lithium-ion batteries)
Consumers and manufacturers have ramped up their interest in this convenient charging technology, abandoning fiddling with plugs and cables in a favour of just setting the phone directly on a charging base.
Spurred by calculations showing that companies with a lower environmental impact are less of a financial risk, banks are beginning to offer cheaper loans if chemical firms hit agreed-upon levels of environmental performance. In this way, companies and banks can obtain a mutually beneficial relationship through green finance, according to an article in Chemical and Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society.
Nanowires promise to make LEDs more colorful and solar cells more efficient, in addition to speeding up computers. That is, provided that the tiny semiconductors convert electric energy into light, and vice versa, at the right wavelengths. A research team at the German Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has managed to produce nanowires with operating wavelengths that can be freely selected over a wide range - simply by altering the shell structure. Fine-tuned nanowires could take on several roles in an optoelectronic component.
Increasingly, shoppers are choosing nutraceuticals, cosmetics and herbal remedies with natural ingredients, and these products are readily available in many drug stores and supermarkets. But some consumers, health professionals and policy makers have raised concerns about the safety, quality and effectiveness of some of these health products. Now, researchers in ACS' Journal of Agricultural and Food Chemistry have developed a method to authenticate botanical ingredients by giving them each a unique "chemical barcode."
Composers string notes of different pitch and duration together to create music. Similarly, cells join amino acids with different characteristics together to make proteins. Now, researchers have bridged these two seemingly disparate processes by translating protein sequences into musical compositions and then using artificial intelligence to convert the sounds into brand-new proteins. They report their results in ACS Nano. Watch how they did it here.
Bees are valuable to humans not only because they produce honey, but also because they pollinate wildflowers and food crops. They exclusively eat nectar and pollen. So in areas where intensive agriculture is practised, they suffer from the thin supply of flowers in May and June, when cultivated oilseed rape (colza) and sunflower are not in bloom. During that period, pollen collection, honey production, and colony growth slow. An article published in the Journal of Applied Ecology shows that organic farming can limit this decline.
A new study demonstrates, for the first time, that "social robots" used in support sessions held in pediatric units at hospitals can lead to more positive emotions in sick children.
Each day, more than 2 billion cups of coffee are consumed worldwide.
Developing countries produce about 90% of the beans used to make all those lattes, espressos and mochas. That makes coffee a key source of revenue and livelihood for millions of people worldwide.
But coffee plants have up-and-down yield patterns. Years with high yields are often followed by years with low yields and vice-versa. This alternating pattern of high and low yields is called the "biennial effect".
PHILADELPHIA - A simple set of decision-support tools combined with institutional buy-in can help increase the number of cancer patients who engage in treatment to help them quit tobacco, data from researchers in the Abramson Cancer Center at the University of Pennsylvania show. The study is based on researchers' clinical experience with Penn's Tobacco Use Treatment Service (TUTS), which combines technology tied to electronic health records with tried and true treatment methods to support patients in their efforts to kick their habit for good.
WEST LAFAYETTE, Ind. - Run, hide, fight. It has become a mantra for how to act during an active shooter situation. The idea is to escape the situation or protect oneself, and counter the gunman as a last resort.
