By using a combination of ultrasound, gold-covered particles and lasers, researchers from UC Santa Barbara and the private medical device company Sebacia have developed a targeted therapy that could potentially lessen the frequency and intensity of breakouts, relieving acne sufferers the discomfort and stress of dealing with severe and recurring pimples.

The 2014 chemistry Nobel Prize recognized important microscopy research that enabled greatly improved spatial resolution. This innovation, resulting in nanometer resolution, was made possible by making the source (the emitter) of the illumination quite small and by moving it quite close to the object being imaged. One problem with this approach is that in such proximity, the emitter and object can interact with each other, blurring the resulting image. Now, a new JQI study has shown how to sharpen nanoscale microscopy (nanoscopy) even more by better locating the exact position of the light source.

Graphene is a remarkably strong material given it's only a single carbon-atom thick. But finding ways to do something with it – that's also affordable too – have always been a challenge.

Nanoparticle electrodes in lithium-ion batteries have both near-surface and interior contributions to their redox capacity, each with distinct rate capabilities. Using combined electron microscopy, synchrotron X-ray methods and ab initio calculations, Brookhaven National Laboratory researchers have investigated the lithiation pathways that occur in NiO electrodes. They found that the near-surface electroactive (Ni2+→Ni0) sites saturated very quickly, and then encountered unexpected difficulty in propagating the phase transition into the electrode (referred to as a "shrinking-core" mode).

Diaper rash may not be a serious condition, but it can be extremely painful. It is common and causes concern for many parents trying to comfort their child.

The spinal cord transmits pain signals to the brain, where they are consciously perceived. But not all the impulses arrive at their destination: Certain neurons act as checkpoints and determine whether a pain signal is relayed or not. Researchers from UZH identified these neurons and their connections. Moreover, they developed means to specifically activate these neurons, which reduces not only pain – but astonishingly also alleviates itch.

In recent years, a deficiency of vitamin D has been linked to type 2 diabetes and heart disease, two illnesses that commonly occur together and are the most common cause of illness and death in Western countries. Both disorders are rooted in chronic inflammation, which leads to insulin resistance and the buildup of artery-clogging plaque.

The human genome can be very forgiving. When children inherit chromosomes from their parents, some minor genetic changes frequently occur with few, if any, consequences. One exception, as researchers report in the March 19 issue of the American Journal of Human Genetics, is chromosomal shattering, termed chromothripsis, which the authors found in healthy mothers who had each given birth to a severely affected child. The findings could have important implications for genetic testing and issues related to infertility.

Across much of the Western world, 25 years of expansion of the medical system has actually led to people feeling less healthy over time, a new study has found.

There is no doubt that teenage boys and girls are swayed and shaped by music TV. For example, sexually active youth of both genders, after watching music TV, think their peers are sexually active, too. Moreover, when girls and boys perceive males in music videos as being sexually active, it makes boys watch more music TV, and girls watch less. These are some of the surprising findings from a study conducted at the Catholic University of Leuven in Belgium, published in Springer's journal Sex Roles. The results question the frequently reported blanket influence of the mass media on teenagers' sexual behavior.

The kidney carries out vital functions by continuously filtering the blood and excreting waste products into the urine. This is achieved by a complex system of tubules which transports the urine and regulates its composition. PhD student Annekatrin Aue, Dr. Christian Hinze and Professor Kai Schmidt-Ott of the Max Delbrück Center for Molecular Medicine (MDC) have now discovered how parts of these kidney tubules establish an inner space (lumen) and form a tight barrier against adjacent structures. The epithelial cells which line the tubules coordinate these processes through a novel molecular signaling pathway.

Researchers at the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch and Charité - Universitätsmedizin Berlin, Campus Berlin-Buch, have succeeded in generating cells of the immune system to specifically target and destroy cancer cells.

Rust never sleeps. Whether a reference to the 1979 Neil Young album or a product designed to protect metal surfaces, the phrase invokes the idea that corrosion from oxidation—the more general chemical name for rust and other reactions of metal with oxygen—is an inevitable, persistent process. But a new study performed at the Center for Functional Nanomaterials (CFN) at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory reveals that certain features of metal surfaces can stop the process of oxidation in its tracks.

(Phys.org)—Cytochrome P450 (CYP) is sometimes referred to as the "Rosetta Stone" of iron-containing oxygenases, because of its ubiquity as a biocatalyst for various reactions, including drug metabolism and synthesis of biological molecules. Importantly, CYP catalyzes carbon-hydrogen hydroxylation reactions, cleaving some of the most difficult carbon-hydrogen bonding structures. While CYP is well studied, scientists are eager to understand the ferryl intermediates formed during hydroxylation in an effort to fine-tune catalytic reactions as well as seek out other biocatalysts to react with carbon-hydrogen bonds that are typically unreactive.

For the first time ever, a team of scientist from the University of Cologne headed by Professor Stephan Schlemmer succeeded in understanding the spectrum of the highly fluxional molecule CH5+.
