ITHACA, N.Y. – When you spill pasta sauce on your favorite shirt but there is no trace of it after being washed, you can thank oleophobicity, a resistance to oil commonly applied to textiles. That resistance, however, comes at a price. The coating that makes textiles oil resistant is fluorine-based and breaks down into chlorofluorocarbon gas, a greenhouse gas harmful to the environment.
An international team of scientists has developed a new way to produce single-layer graphene from a simple precursor: ethene – also known as ethylene – the smallest alkene molecule, which contains just two atoms of carbon.
Water-splitting systems require a very efficient catalyst to speed up the chemical reaction that splits water into hydrogen and oxygen, while preventing the gases from recombining back into water. Now an international research team, including scientists at the Department of Energy’s SLAC National Accelerator Laboratory, has developed a new catalyst with a molybdenum coating that prevents this problematic back reaction and works well in realistic operating conditions.

Approximately 10-20 percent of white dwarfs exhibit strong magnetic fields, some of which can reach up to 100,000 tesla. In comparison, on Earth, the strongest magnetic fields that can be generated using nondestructive magnets are about 100 tesla. Therefore, studying the chemistry in such extreme conditions is only possible using theory and until now has not provided much insight to the spectra accompanying white dwarfs. Researchers in Germany describe their work modeling these systems this week in The Journal of Chemical Physics.
According to the National Cancer Institute, nearly one-third of cancer deaths can be attributed to a wasting syndrome known as cachexia. Cachexia, an indicator of the advanced stages of disease, is a debilitating disorder that causes loss of appetite, lean body mass and can lead to multi-organ failure. Now, researchers at the University of Missouri in partnership with Tensive Controls, Inc. have developed a drug that could reverse cachexia. The team currently is seeking canine candidates for a pilot study to test the new drug.

According to the Cystic Fibrosis Foundation, more than 30,000 Americans are living with the disorder. It currently has no cure, though a drug approved by the Food and Drug Administration treats the underlying cause of the disease. However, the drug’s effectiveness for each individual is unknown. Researchers from the University of Missouri School of Medicine have developed an imaging technique using a specific form of helium to measure the drug’s effectiveness. Researchers hope the finding could lead to improved therapies for cystic fibrosis and other lung conditions.
Diabetes researchers have puzzled for decades about why insulin-producing beta cells in one pancreatic islet often look and behave quite differently than their counterparts in the same islet or in nearby islets. Using newly identified cellular markers of aging, Joslin Diabetes Center scientists now have shown that this diversity may be driven at least in part by differently aged beta cell populations within the pancreas.

When DNA is hit with ultraviolet light, it can lose excess energy from radiation by ejecting the core of a hydrogen atom — a single proton — to keep other chemical bonds in the system from breaking. To gain insight into this process, researchers used X-ray laser pulses from the Linac Coherent Light Source (LCLS) at the Department of Energy’s SLAC National Accelerator Laboratory to investigate how energy from light transforms a relatively simple molecule, 2-thiopyridone.
