Take a material that is a focus of interest in the quest for advanced solar cells. Discover a “freshman chemistry level” technique for growing that material into high-efficiency, ultra-small lasers. The result, disclosed today [Monday, April 13] in Nature Materials, is a shortcut to lasers that are extremely efficient and able to create many colors of light.
Researchers at The University of Manchester have made a significant breakthrough in the development of synthetic pathways that will enable renewable biosynthesis of the gas propane. This research is part of a programme of work aimed at developing the next generation of biofuels.
Using a powerful microscope to watch multiple cycles of charging and discharging under real battery conditions, researchers have gained insight into the chemistry that clogs rechargeable lithium batteries in work appearing in the March issue of the journal Nano Letters.
Detecting problems with lysosomes is the focus of a new set of fluorescent probes developed by researchers at Michigan Technological University. The Royal Society of Chemistry published their work in January.

Consumers are one step closer to benefiting from packaging that could give simple text warnings when food is contaminated with deadly pathogens like E. coli and Salmonella, and patients could soon receive real-time diagnoses of infections such as C. difficile right in their doctors’ offices, saving critical time and trips to the lab. Researchers at McMaster University have developed a new way to print paper biosensors, simplifying the diagnosis of many bacterial and respiratory infections.

A small team of chemists, having learned the secrets of light absorption from chlorophylls a and b, can now tune molecules to absorb anywhere in the solar spectrum. They are using this facility to synthesize pigments that fill gaps in the sunlight absorbed by native pigments and to push deeper into the infrared than any native pigment
The first-ever perfume delivery system to ensure the more a person sweats, the better they will smell, has been developed by scientists at Queen’s University Belfast.
An international team has for the first time precisely tracked the surprisingly rapid process by which light rearranges the outermost electrons of a metal compound and turns it into an active catalyst – a substance that promotes chemical reactions.
Penn Medicine researchers are continuing their work in trying to understand the mechanisms through which anesthetics work to elicit the response that puts millions of Americans to sleep for surgeries each day. Their most recent study looked at ketamine, an anesthetic discovered in the 1960s and more recently prescribed as an anti-depressant at low doses. Through collaboration with the University of Pennsylvania’s department of Chemistry and scientists at the Duke University Medical Center, researchers at Penn’s Perelman School of Medicine have identified an entirely new class of receptors that ketamine binds in the body, which may underlie its diverse actions.
A new study out of West Virginia University suggests antioxidants may play a key role in reducing the long-term effects of concussions and could potentially offer a unique new approach for treatment.
Research has discovered a role for prolactin, the hormone that stimulates milk production in nursing mothers, in the bond between parents. The study on cotton-top tamarins found a link between prolactin levels and sexual activity and cuddling among paired adults. Although this was a first for prolactin, it has previously been found for oxytocin, a hormone that stimulates childbirth and is linked to a range of pleasurable emotions.
An international team of more than 18 research groups has demonstrated that the compounds they developed can safely prevent harmful protein aggregation in preliminary tests using animals. The findings raise hope that a new class of drugs may be on the horizon for the more than 30 diseases and conditions that involve protein aggregation, including diabetes, cancer, spinal cord injury, Alzheimer’s disease, Parkinson’s disease and amyotrophic lateral sclerosis (ALS).
Biological Science Assistant Professor Elizabeth Stroupe and Associate Professor Hank Bass, along with molecular biophysics graduate student Mykhailo Kopylov, write in a new Biochemistry paper that the same type of protein works in plants and animals to bind to peculiar DNA structures called G-quadruplexes, or G4 DNA for short.
Theodore Betley, Ph.D., will present his pioneering work in catalysis, which could help harness greenhouse gases, during today’s “The Kavli Foundation Emerging Leader in Chemistry Lecture” at the 249th National Meeting & Exposition of the American Chemical Society.
The American Chemical Society (ACS) will publish the first issue of its multidisciplinary high-impact journal ACS Central Science today. This morning, the journal’s editor-in-chief, representatives of the editorial board and ACS staff will discuss the journal’s vision in a press conference at the Society’s 249th National Meeting & Exposition.
The Board of Directors of the American Chemical Society will recognize the Organisation for the Prohibition of Chemical Weapons for its tireless efforts in promoting the peaceful use of chemistry at the Society’s 249th National Meeting & Exposition.
In this Q&A Andrew Stack, a geochemist at the Department of Energy’s Oak Ridge National Laboratory, advances understanding of the dynamics of minerals underground. Stack and his team make discoveries that will help to improve our understanding of a wide range of energy-related issues, such as geologic storage of carbon dioxide, oil and gas discovery and development, and remediation of toxic contaminants. His current research spans three disciplines—geology, chemistry and computing.
Cod liver oil and willow bark extract used in the tanning of skins for clothing and other products offer notable differences in treatment, a study by a team of scientists shows. Their findings show the promise of a technique that may be used to identify the aging behavior of materials and to examine delicate works of art.
