For the first time, McGill researchers have been able to take a series of 3D images of a large section from one of the medicine-synthesizing enzymes in action. The researchers believe that the images they have generated will not only bring scientists closer to understanding how many antibiotics are made, but could, with further research, lead to the development of much needed next-generation antibiotics.

In a recent experiment, Argonne battery scientists Jun Lu, Larry Curtiss and Khalil Amine, along with American and Korean collaborators, were able to produce stable crystallized lithium superoxide (LiO2) instead of lithium peroxide during battery discharging. Unlike lithium peroxide, lithium superoxide can easily dissociate into lithium and oxygen, leading to high efficiency and good cycle life.

Scientists at the Gladstone Institutes and the University of California, San Francisco (UCSF) have successfully converted human skin cells into fully-functional pancreatic cells. The new cells produced insulin in response to changes in glucose levels, and, when transplanted into mice, the cells protected the animals from developing diabetes in a mouse model of the disease.

A team of investigators based in Seattle, Amsterdam, and Luxembourg, have established the cause of a rare syndrome consistent with Fanconi Anemia, a chromosome instability disorder which is clinically typified by birth defects, bone marrow failure, leukemia, and susceptibility to solid tumors. The results were reported by researchers from the Institute for Systems Biology (Seattle), the Free University Medical Center in Amsterdam, and the Luxembourg Centre for Systems Biomedicine and several other institutions in the United States and Europe in the journal Nature Communications on December 18, 2015 (DOI: 10.1038/ncomms9829).

Different groups of neurons “predict” the body’s subsequent looking and reaching movements, suggesting an orchestration among distinct parts of the brain, a team of neuroscientists has found. The study enhances our understanding of the decision-making process, potentially offering insights into different forms of mental illness—afflictions in which this dynamic is typically impaired.

Scientists at three Department of Energy national laboratories have discovered how to keep a promising new type of lithium ion battery cathode from developing a crusty coating that degrades its performance. The solution: Use a simple manufacturing technique to form the cathode material into tiny, layered particles that store a lot of energy while protecting themselves from damage.

Lithium nickel manganese cobalt oxide, or NMC, is one of the most promising chemistries for better lithium batteries, especially for electric vehicle applications, but scientists have been struggling to get higher capacity out of them. Now researchers at Lawrence Berkeley National Laboratory have found that using a different method to make the material can offer substantial improvements.

Seashells and lobster claws are hard to break, but chalk is soft enough to draw on sidewalks. Though all three are made of calcium carbonate crystals, the hard materials include clumps of soft biological matter that make them much stronger. A study today in Nature Communications reveals how soft clumps get into crystals and endow them with remarkable strength.

Fibrocartilage tissue in the knee is comprised of a more varied molecular structure than researchers previously appreciated. The work informs ways to better treat such injuries as knee meniscus tears – treatment of which are the most common orthopaedic surgery in the United States -- and age-related tissue degeneration, both of which can have significant socioeconomic and quality-of-life costs.

A team at the Weizmann Institute of Science found that when spherical nanoparticles self-assembled into a cluster, empty spaces – “flasks” – formed between them, as between oranges packed in a case. They were able to produce a range of chemical reactions in the flasks that were 100 times faster than in solution. The many potential applications include drug delivery.

In its simplest terms, weight loss occurs when the amount of energy consumed in the form of food is less than the amount of energy burned. This can be accomplished by eating less or exercising more. With either approach, the goal is to create a caloric debt that will be resolved by burning stored carbohydrate, protein, or fat. Challenges to losing the holiday weight (alternatively a beer gut, Freshman Fifteen, etc.) are simple: eating feels good and being hungry is uncomfortable.
