Hypothalamic neurons orchestrate many essential physiological and behavioral processes via secreted neuropeptides, and are relevant to human diseases such as obesity, narcolepsy and infertility. A recent collaboration of scientists from New York, Toronto, and Tokyo, and Harvard Stem Cell Institute (HSCI) researchers have devised two methods for using stem cells to generate the type of neurons that help regulate behavioral and basic physiological functions in the human body, such as obesity and hypertension, as well as sleep, mood, and some social disorders.

By combining time-lapse luminescence microscopy with a microfluidic device, researchers at Duke University were able to track the dynamics of cell cycle genes in single yeast with subminute exposure times over many generations. Typically time-lapse fluorescence microscopy of genetically encoded fluorescent proteins is the gold standard for measuring in vivo dynamics of gene expression in single cells.

Biofuels, Bioproducts and Biopower
UGA's bioenergy researchers are helping transform the nation's renewable and abundant biomass resources into cost-competitive, high-performance biofuels, bioproducts and biopower that are needed to meet growing energy needs. Almost 30 biobased technologies have been developed at UGA, with many licensed to the marketplace: genetically modified plants for the production of biofuels and biochemicals, methods for quantitative analysis of biomass, genetically engineered microorganisms for the production of a variety of chemicals from plants, and a process to turn woody waste biomass into a liquid fuel.

When the level of blood glucose, also called blood sugar, rises after a meal, the pancreas responds by releasing insulin into the bloodstream. Insulin helps cells throughout the body absorb glucose from the bloodstream and use it for energy.

June 2014, Rutgers University began a project to build a new state-of-the-art research facility. The four-story, 145,000 square-foot facility will provide critically needed teaching, laboratory and support space that will enable Rutgers to expand and accelerate its innovative research in drug design, alternative energy, biomaterials and nanotechnology.

San Francisco’s Mission Bay district became a magnificent conglomeration of colors and excitement as celebrities, civic dignitaries, and community members celebrated the upcoming opening of the new UCSF Medical Center with a lights-on festival and a hard hat walk. Adding excitement to the event were Jesse Tyler Ferguson, star of the ABC television show “Modern Family,” Olympic champion figure skater Kristi Yamaguchi and San Francisco Giants home run king Barry Bonds, a longtime friend and supporter of UCSF Benioff Children’s Hospital San Francisco.

Researchers at UC Davis and other institutions have found that diets rich in whole walnuts or walnut oil, slowed prostate cancer growth in mice. In addition, both walnuts and walnut oil reduced cholesterol and increased insulin sensitivity (when you have high insulin sensitivity, you are able to eat carbohydrates without such a large rise in insulin. When insulin is kept low enough, fatty acids can still be released). The walnut diet also reduced levels of the hormone IGF-1, which had been previously implicated in both prostate and breast cancer. The study was published online in the Journal of Medicinal Food.
