One of the biggest difficulties faced by worldwide programs aimed at eliminating malaria is that the tests they use are not sensitive enough to detect all people who have the disease and need treatment. A study appearing online today in Clinical Chemistry, the journal of AACC, shows that a new test known as capture and ligation probe-PCR (CLIP-PCR) could diagnose the malaria cases that would typically escape detection and lead to new infections.

Research teams led by Edward Yu of Iowa State University and the Ames Laboratory have described the structure of two closely related protein pumps that allow bacteria to resist certain medications.
University at Buffalo researchers have discovered a way to easily and effectively fasten proteins to nanoparticles – essentially an arranged marriage – by simply mixing them together. The biotechnology, described April 20 online in the journal Nature Chemistry, is in its infancy. But it already has shown promise for developing an HIV vaccine and as a way to target cancer cells.
A new mathematical model that uses drug-target kinetics to predict how drugs work in vivo may provide a foundation to improve drug discovery, which is frequently hampered by the inability to predict effective doses of drugs. The discovery by Peter Tonge, a Professor of Chemistry and Radiology, and Director of Infectious Disease Research at the Institute for Chemical Biology and Drug Discovery (ICB & DD) at Stony Brook University, along with collaborators at Stony Brook University and AstraZeneca, will be published advanced online on April 20 in Nature Chemical Biology.
Climate models calculate a changing mix of clouds and emissions that interact with solar energy. To narrow the broad range of possible answers from a climate model, researchers analyzed the effect of several proven numerical stand-ins for atmospheric processes on the energy flux at the top of the atmosphere. They found that the flux is the main driver of surface temperature change.
By combining biocompatible light-capturing nanowire arrays with select bacterial populations, a potentially game-changing new artificial photosynthesis system offers a win/win situation for the environment: solar-powered green chemistry using sequestered carbon dioxide.
A little-known element called californium is making big waves in how scientists look at the periodic table. According to new research by a Florida State University professor, californium is what’s known to be a transitional element, meaning it links one part of the Periodic Table of Elements to the next.
Neuroscientists at NYU Langone Medical Center have discovered how the powerful brain hormone oxytocin acts on individual brain cells to prompt specific social behaviors – findings that could lead to a better understanding of how oxytocin and other hormones could be used to treat behavioral problems resulting from disease or trauma to the brain.
A new breakthrough battery—one that has significantly higher energy, lasts longer, and is cheaper and safer—will likely be impossible without a new material discovery. And a new material discovery could take years, if not decades, since trial and error has been the best available approach. But Lawrence Berkeley National Laboratory scientist Kristin Persson says she can take some of the guesswork out of the discovery process with her Electrolyte Genome.

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.
