Biology isn't just for biologists anymore. That's nowhere more apparent than in the newly furnished lab in room 097 of the Shriram Center basement, where flasks of bacterial and animal cells, snug in their incubators, are churning out proteins destined for jobs they may not have done in nature.
A team of researchers at The University of Texas at Dallas has developed a novel method for trapping potentially harmful gases within microscopic organo-metallic structures. These metal organic frameworks, or MOFs, are made of different building blocks composed of metal ion centers and organic linker molecules. Together they form a honeycomb-like structure that can trap gases within each comb, or pore.
the global economy and have been the subject of research for decades. Despite their unique advantages, x-ray synchrotron spectroscopy techniques were not widely employed by those delving into the intricacies The Synchrotron Catalysis Consortium was established to address this situation by providing scientists a means to study catalysts at work under realistic conditions and developing new techniques to characterize catalysts.
RICHLAND, Wash. – Water has many unusual properties, such as its solid form, ice, being able to float in liquid water, and they get weirder below its freezing point. Supercooled water — below freezing but still a liquid — is notoriously difficult to study. Some researchers thought supercooled water behaved oddly within a particularly cold range, snapping from a liquid into a solid, instantaneously crystallizing at a particular temperature like something out of a Kurt Vonnegut novel.
Northern Michigan University will offer the only four-year degree of its kind in medicinal plant chemistry that combines experimental horticulture and advanced analytical chemistry with an optional entrepreneurial track. Students will gain knowledge and skills applicable to the emerging cannabis and herbal supplement industries, food and fermentation science, environmental analysis, various lab positions or graduate school.

Pitt chemical engineering team identifies new catalyst that advances capture and conversion of atmospheric carbon dioxide
Scientists have called superoxide out as the main culprit behind coral bleaching: The idea is that as this toxin build up inside coral cells, the corals fight back by ejecting the tiny energy- and color-producing algae living inside them. In doing so, they lose their vibrancy, turn a sickly white, and are left weak, damaged, and vulnerable to disease.
Scott Crooker, of Los Alamos National Laboratory’s Condensed Matter and Magnet Science group, and William Charles Louis III, of the Laboratory’s Physics Division, have been named Fellows of the American Association for the Advancement of Science (AAAS). Election as an AAAS Fellow is an honor bestowed upon AAAS members by their peers.

A new commentary cautions that the Food and Drug Administration’s ban on triclosan and 18 other biocidal chemicals that promote antibiotic resistance is only a starting point. Triclosan’s long-term impact, as well the risks substitute chemicals may pose, must also be addressed.
A new study has revealed similarities and relationships between certain types of chemicals found on 30 different comets, which vary widely in their overall composition compared to one another. The research is part of ongoing investigations into these primordial bodies, which contain material largely unchanged from the birth of the solar system some 4.6 billion years ago.
Water conducts electricity, but the process by which this familiar fluid passes along positive charges has puzzled scientists for decades. But in a paper published in the Dec. 2 in issue of the journal Science, an international team of researchers has finally caught water in the act — showing how water molecules pass along excess charges and, in the process, conduct electricity.
Simon Bare, who joined the Department of Energy’s SLAC National Accelerator Laboratory in April, spent 30 years as an industrial chemist investigating how catalysts work. Now, as co-director of the Chemistry and Catalysis Division at the lab’s Stanford Synchrotron Radiation Lightsource (SSRL), his goal is to build on research strengths at SLAC and Stanford University to create a West Coast center for catalyst research and define new research directions.

Traditional cigarettes pose a well-established risk to smokers' health, but the effects of electronic cigarettes are still being determined. Helping to flesh out this picture, researchers are reporting in the ACS journal Environmental Science & Technology what happens to e-liquid flavorings when they're heated inside e-cigarettes or electronic nicotine-delivery systems. The study found that when converted into a vapor, some flavorings break down into toxic compounds at levels that exceed occupational safety standards.
In recent years, environmental groups have been calling out cosmetic preservatives as suspected endocrine disruptors, cancer-causing agents and skin irritants. The campaigns have resulted in new restrictions on certain preservatives. But, as reported in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, the shrinking list of approved preservatives is having unintended consequences.
Doctors, pilots, air traffic controllers and bus drivers have at least one thing in common — if they're exhausted at work, they could be putting lives at risk. But the development of a new urine test, reported in the ACS journal Analytical Chemistry, could help monitor just how weary they are. The results could potentially reduce fatigue-related mistakes by allowing workers to recognize when they should take a break.
In colder weather, people have long been warming up around campfires and woodstoves. Lately, this idea of burning wood or other biomass for heat has surged in popularity as an alternative to using fossil fuels. Now, in the journal ACS Sustainable Chemistry & Engineering, scientists report a step toward a "greener" way to generate heat with biomass. Rather than burning it, which releases pollutants, they let fungi break it down to release heat.
That bright, reflective coating used on road signs, bicycles and clothing are important safety measures at night. They help drivers get to their destinations while avoiding bicyclists and pedestrians in low-light conditions. Now, inspired by the structure of insect eyes, scientists have developed new materials that could improve the color and effectiveness of these safeguards. Their report appears in the ACS journal Langmuir.
