Researchers at Columbia University Medical Center (CUMC) have devised a hair restoration method that can generate new human hair growth, rather than simply redistribute hair from one part of the scalp to another. The approach could significantly expand the use of hair transplantation to women with hair loss, who tend to have insufficient donor hair, as well as to men in early stages of baldness. The study was published today in the online edition of the Proceedings of the National Academy of Sciences (PNAS).

In this week’s issue of Nature Photonics scientists at the Joint Quantum Institute (*) report the first observation of topological effects for light in two dimensions, analogous to the quantum Hall effect for electrons. To accomplish this, they built a structure to guide infrared light over the surface of a room temperature, silicon-on-insulator chip.

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have identified the key genes required for oil production and accumulation in plant leaves and other vegetative plant tissues. Enhancing expression of these genes resulted in vastly increased oil content in leaves, the most abundant sources of plant biomass-a finding that could have important implications for increasing the energy content of plant-based foods and renewable biofuel feedstocks.

Men with low-pitched voices have an advantage in attracting women, even though women know they’re not likely to stick around for long. Researchers at McMaster University have found that women were more attracted to men with masculine voices, at least for short-term relationships. Those men were also seen as more likely to cheat and unsuitable for a longer relationship, such as marriage.

Severe liver damage, and even failure, has been associated with the consumption of weight loss supplements, an herbal supplement and an energy drink, according to four separate case reports presented at the American College of Gastroenterology’s 78th Annual Scientific Meeting in San Diego, CA. Use of herbal and dietary supplements is widespread for a variety of health problems. Because many patients do not disclose supplement use to their physicians, important drug side effects can be missed.

When you heat a tiny droplet of liquid tin with a laser, plasma forms on the surface of the droplet and produces extreme ultraviolet (EUV) light, which has a higher frequency and greater energy than normal ultraviolet. Now, for the first time, researchers have mapped this EUV emission and developed a theoretical model that explains how the emission depends on the three-dimensional shape of the plasma. In doing so, they found a previously untapped source of EUV light, which could be useful for various applications including semiconductor lithography, the process used to make integrated circuits.

Mitochondria are the power plants of cells, manufacturing fuel so a cell can perform its many tasks. These cellular power plants also are well known for their role in cell suicide. Now, researchers at Washington University School of Medicine in St. Louis and the University of Padua-Dulbecco Telethon Institute in Italy have shown that mitochondria remarkably also orchestrate events that determine a cell’s future, at least in the embryonic mouse heart. The new study identifies new potential genetic culprits in the origins of some congenital heart defects.
