Tighter tummies: A new way to combat weight gain 
Two cell proteins that relax the gut and help accommodate a big meal have been identified by UCL scientists. The proteins could offer a future drug target against weight gain, by preventing the stomach from expanding.

USC researchers discover novel way to develop tumor vaccines
Researchers at the University of Southern California (USC) have uncovered a new way to develop more effective tumor vaccines by turning off the suppression function of regulatory T cells. The results of the study, titled “A20 is an antigen presentation attenuator, and its inhibition overcomes regulatory T cell-mediated suppression,” will be published in Nature Medicine on March 2, 2008.

Student Develops New LED, Wins $30,000 Lemelson-Rensselaer Prize
In recent years, light emitting diodes (LEDs) have begun to change the way we see the world. Now, a Rensselaer Polytechnic Institute student has developed a new type of LED that could allow for their widespread use as light sources for liquid crystal displays (LCDs) on everything from televisions and computers to cell phones and cameras.

Blocking protein kills prostate cancer cells, inhibits tumor growth
Researchers at Jefferson’s Kimmel Cancer Center in Philadelphia have shown that they can effectively kill prostate cancer cells in both the laboratory and in experimental animal models by blocking a signaling protein that is key to the cancer’s growth. The work proves that the protein, Stat5, is both vital to prostate cancer cell maintenance and that it is a viable target for drug therapy.

Notch controls bone formation and strength
Notch, a protein known to govern the determination of cell differentiation into different kinds of tissues in embryos, plays a critical role in bone formation and strength later in life, said researchers from Baylor College of Medicine in Houston in a report that appears online today in the journal Nature Medicine.

Special coating greatly improves solar cell performance
The energy from sunlight falling on only 9 percent of California’s Mojave Desert could power all of the United States’ electricity needs if the energy could be efficiently harvested, according to some estimates. Unfortunately, current-generation solar cell technologies are too expensive and inefficient for wide-scale commercial applications.

Prions link cholesterol to neurodegeneration
Prion infection of neurons increases the free cholesterol content in cell membranes. A new study published in the online open access journal BMC Biology suggests that disturbances in membrane cholesterol may be the mechanism by which prions cause neurodegeneration and could point to a role for cholesterol in other neurodegenerative diseases.

Other vertebrates such as fish, reptiles, and birds, have red cells that contain nuclei that are inactive.
