In 1924, Russian biochemist Alexander Oparin claimed that life developed through chemical changes of organic molecules. The Weizmann Institute’s Prof. Doron Lancet has now made discoveries about lipids that support Oparin’s ideas. Lancet’s findings could also help identify early, lipid-based life forms on other worlds.
The U.S. Department of Energy (DOE) announced funding for research that will take advantage of new and emerging capabilities to probe materials and chemical processes at time scales of a quadrillionth of a second or less.
Chemists at Argonne and Ames national laboratories have spotted an important and unexpected reaction mechanism — called redox behavior — in some catalyst support materials that are commonly used in the chemical industry.
Los Alamos National Laboratory Fellow Jaqueline Loetsch Kiplinger has been announced as a fellow of the American Chemical Society. She is among 51 new fellows for the nation’s key chemistry organization and is one of only seven from Los Alamos in the laboratory’s 75-year history.
A team of researchers recently discovered a new aspirin polymorph that’s predicted to dissolve faster than current form I aspirin tablets, which would mean faster pain relief after ingestion. Greater dissolving efficiency also means that each tablet would require less of the compound. Chunhua (Tony) Hu, New York University, will present the painstaking story of aspirin IV alongside its structural definition at the 68th Annual Meeting of the American Crystallographic Association.
Phospholipases are enzymes that cleave the tail group off of phospholipids, which make up cell membranes. These tails, or free fatty acids, can go on to act as signaling molecules. Lysosomal phospholipase A2, or LPA2, is a phospholipase from the macrophages that protect the lung.
People with chronic kidney disease are at unusually high risk of also developing cardiovascular disease; in fact, a patient with non-dialysis kidney disease is more likely to die of heart failure than to develop end-stage kidney failure. However traditional atherosclerosis risk factors contribute less strongly to cardiovascular disease in chronic kidney disease patients than in subjects with intact kidney function.
Researchers at Georgia Institute of Technology have created a material derived from crab shells and tree fibers that has the potential to replace the flexible plastic packaging used to keep food fresh.
Many vaccines become ineffective when exposed to room temperature or heat. This challenge can prevent patients from accessing lifesaving immunizations and increase the risk of global pandemics. During the 68th Annual Meeting of the American Crystallographic Association, Jeremiah Gassensmith, University of Texas at Dallas, will describe his lab’s work developing metal-organic framework vaccines. This new biocompatible polymer framework “freezes” proteins inside vaccines. The proteins then dissolve when injected in human skin. This innovation could help health care providers transport and administer vaccines in remote areas with unreliable power.
Diener Precision Pumps plans to launch their new Silencer LD gear pump at the AACC exhibition in Chicago, July 31st - August 2nd. Booth 4409.
A clinical trial is currently underway to evaluate the predictive values of the STELLUX® Chemiluminescence Calprotectin ELISA for the diagnosis of inflammatory bowel diseases (IBDs), specifically Crohn's disease (CD) and ulcerative colitis (UC). The clinical trial will evaluate the use of the assay to aid in the differentiation of IBD from irritable bowel syndrome (IBS) when used in conjunction with other diagnostic testing.
Studying the photochemistry has shown that ultraviolet radiation can set off harmful chemical reactions in the human body and, alternatively, can provide “photo-protection” by dispersing extra energy. To better understand the dynamics of these photochemical processes, a group of scientists irradiated the RNA base uracil with ultraviolet light and documented its behavior on a picosecond timescale. They discuss their work this week in The Journal of Chemical Physics.
A new molecule designed by University of Adelaide researchers shows great promise for future treatment of many cancers.
A team of Florida State University researchers is using artificial intelligence to identify which among hundreds of thousands of hypothetical crystal structures can result in the prediction of new chemical compounds.
By some estimates, 18 million people die each year from sepsis triggered by endotoxins – fragments of the outer membranes of bacteria. A biochemical engineer at Missouri University of Science and Technology has patented a method of removing these harmful elements from water and also from pharmaceutical formulations.Her goal: improve drug safety and increase access to clean drinking water in the developing world.
A stable cell line of Wolbachia-infected fruit fly cells turned out to be an invaluable tool for researchers seeking new drugs to treat river blindness and related diseases. That's because the parasitic worms that cause these diseases are actually dependent on Wolbachia bacteria living within their cells. Kill the Wolbachia, and the worms die.
A review of more than 200 studies reveals that olfactory receptors—proteins that bind to odors that aid the sense of smell—perform a wide range of mostly unknown functions outside the nose. The function of extra-nasal olfactory receptors has the potential to be used in the diagnosis and treatment of health conditions such as cancer.
When most people think of tea and molasses, their thoughts don’t stray any further than the kitchen. Meghana Bollimpalli, a Central High School student who was mentored by two chemistry professors at the University of Arkansas at Little Rock, saw the potential to create a less-expensive renewable energy source that has earned her more than $60,000 in scholarships and prize money from science fair competitions.
The compound urea is currently the most popular nitrogen soil fertilizer. It’s a way to get plants the nitrogen they need to grow. There’s just one problem with urease: it works too well! New research suggests farmers may have a choice in how they slow the release of nitrogen, depending on their soil’s acidity.
