Knowing How Brown Fat Cells Develop May Help Fight Obesity

Perelman School of Medicine at the University of Pennsylvania

Brown fat cells are the professional heat-producing cells of the body. Because of this they are protective against obesity as well as diabetes. A protein switch called early B cell factor-2 determines which developmental path fat precursor cells take – the brown vs. white cell trajectory.

Scientists Map Genome That Causes Dutch Elm Disease

University of Toronto

Researchers from the University of Toronto and SickKids Research Institute announced today that they have successfully mapped the genes in the fungus that causes Dutch Elm Disease. The researchers believe this is the first time the 30 million DNA letters for the fungus Ophiostoma ulmi have been mapped. The findings, published in this week’s online journal BMC Genomics, could help scientists figure out how to prevent the fungus from destroying elm trees in the future.

Sex at Zero Gravity

Universite de Montreal

University of Montreal researchers found that changes in gravity affect the reproductive process in plants. Gravity modulates traffic on the intracellular “highways” that ensure the growth and functionality of the male reproductive organ in plants, the pollen tube.

Joslin Scientists Discover Mechanism That Regulates Production of Energy-Burning Brown Fat

Joslin Diabetes Center

Joslin scientists have discovered a mechanism that regulates the production of brown fat, a type of fat which plays an important role in heat production and energy metabolism. The findings may lead to new therapies that increase BAT formation to treat obesity.

Immune Cells Cluster And Communicate ‘Like Bees,’ Researcher Says

University of California, San Francisco (UCSF)

The immune system’s T cells, while coordinating responses to diseases and vaccines, act like honey bees sharing information about the best honey sources, according to a new study by scientists at UC San Francisco.

Designing Interlocking Building Blocks to Create Complex Tissues

Columbia University School of Engineering and Applied Science

Columbia Engineering’s new “plug-and-play” method to assemble complex cell microenvironments is a scalable, highly precise way to fabricate tissues with any spatial organization or interest—like those found in the heart or skeleton or vasculature. The PNAS study reveals new ways to better mimic the enormous complexity of tissue development, regeneration, and disease.

Pushing the Boundaries

Johns Hopkins Medicine

Researchers at Johns Hopkins have established a high-efficiency cell-cell fusion system, providing a new model to study how fusion works. The scientists showed that fusion between two cells is not equal and mutual as some assumed, but, rather, is initiated and driven by one of the fusion partners. The discovery, they say, could lead to improved treatments for muscular dystrophy, since muscle regeneration relies on cell fusion to make muscle fibers that contain hundreds or even thousands of nuclei.
