#Chemsafety at #ACSSanDiego – The Safety Zone

About the Safety Zone The Safety Zone covers chemical safety issues in academic and industrial research labs and in manufacturing. It is intended to be a forum for exchange and discussion of lab and plant safety and accident information without the fanfare of a news article. Read more » Source link…

Enzyme that helps protect us from stress linked to liver cancer growth — ScienceDaily

An enzyme induced by stress to help reduce production of damaging free radicals is also used by liver cancer to regulate two major cell proliferation pathways that enable the cancer to thrive, scientists report. They’ve also found that when they block the enzyme Nqo1, it dramatically reduces the proliferation of liver cancer cells, a hallmark of cancer’s ability to survive and thrive, they report in the journal HEPATOLOGY. Nqo1 is highly expressed in both their mouse model of liver cancer…

MU Biomedical, Biological & Chemical Engineering senior Kyle Lang maximized his engineering and leadership skills this summer, landing an internship with  Pfizer in St. Louis. Learn a little more about his internship in his own words. Lang: Beyond the many technical insights into the pharmaceutical industry, the most valuable lessons from my summer with Pfizer were to relax and bring energy to the office.…

Food profilers develop new methodological approach for food analysis — ScienceDaily

Scientists at the Technical University of Munich (TUM) and the Leibniz-Institute for Food Systems Biology have developed a new methodology for the simultaneous analysis of odorants and tastants. It could simplify and accelerate the quality control of food in the future. Whether a food tastes good or not is essentially determined by the interaction of odors and tastants. A few trillionths of a gram per kilogram of food is enough to perceive some odorants. Tastants, on the other hand, we…

Strange bacteria hint at ancient origin of photosynthesis — ScienceDaily

Structures inside rare bacteria are similar to those that power photosynthesis in plants today, suggesting the process is older than assumed. The finding could mean the evolution of photosynthesis needs a rethink, turning traditional ideas on their head. Photosynthesis is the ability to use the Sun’s energy to produce sugars via chemical reactions. Plants, algae, and some bacteria today perform ‘oxygenic’ photosynthesis, which splits water into oxygen and hydrogen to power the process, releasing oxygen as a waste product. Some…

Atmosphere of midsize planet revealed by Hubble, Spitzer — ScienceDaily

Two NASA space telescopes have teamed up to identify, for the first time, the detailed chemical “fingerprint” of a planet between the sizes of Earth and Neptune. No planets like this can be found in our own solar system, but they are common around other stars. The planet, Gliese 3470 b (also known as GJ 3470 b), may be a cross between Earth and Neptune, with a large rocky core buried under a deep, crushing hydrogen-and-helium atmosphere. Weighing in at…

X-ray imaging provides clues to fracture in solid-state batteries — ScienceDaily

Solid-state batteries — a new battery design that uses all solid components — have gained attention in recent years because of their potential to hold much more energy while simultaneously avoiding the safety challenges of their liquid-based counterparts. But building a long-lasting solid-state battery is easier said than done. Now, researchers at the Georgia Institute of Technology have used X-ray computed tomography (CT) to visualize in real time how cracks form near the edges of the interfaces between materials in…

Fingerprint spectroscopy within a millisecond

Researchers of Fraunhofer IAF will present their demonstrator of the measuring system at this year’s LASER World of PHOTONICS. Credit: Fraunhofer Institute for Applied Solid State Physics IAF To guarantee high quality pharmaceuticals, manufacturers need not only to control the purity and concentration of their own products, but also those of their suppliers. Researchers at the Fraunhofer Institute for Applied Solid State Physics IAF have developed a measuring system capable of identifying a wide variety of chemical and pharmaceutical substances…

‘DNA microscopy’ offers entirely new way to image cells — ScienceDaily

Microscopy just got reinvented — again. Traditionally, scientists have used light, x-rays, and electrons to peer inside tissues and cells. Today, scientists can trace thread-like fibers of nerves throughout the brain and even watch living mouse embryos conjure the beating cells of a rudimentary heart. But there’s one thing these microscopes can’t see: what’s happening in cells at the genomic level. Now, biophysicist Joshua Weinstein and colleagues have invented an unorthodox type of imaging dubbed “DNA microscopy” that can do…
