Tracking nanoparticles
Using a real-time imaging system, scientists have tracked a group of near-infrared fluorescent nanoparticles from the airspaces of the lungs into the body and out again, providing a description of the characteristics and behavior of the particles that could be used in developing therapeutic agents to treat pulmonary disease.

‘Another set of fingers’
An interdisciplinary group of leading Harvard geneticists and stem cell researchers has found a new genetic aspect of cell reprogramming that may ultimately help in the fine-tuning of induced pluripotent stem cells (iPS) into specific cell types.
-
Obesity rate will reach at least 42%
Researchers at Harvard University say America’s obesity epidemic won’t plateau until at least 42 percent of adults are obese, an estimate derived by applying mathematical modeling to 40 years of Framingham Heart Study data.

An initial study of a new treatment for a form of lung cancer seems so promising it has been jumped from Phase 1 to Phase 3 clinical trials.
-
Fuel efficiency for marathoners
Inspired by his experience in the 2005 New York Marathon, an M.D./Ph.D. student has taken a rigorous approach to calculating just how much carbohydrate a runner needs to fuel himself or herself through 26.2 miles, and what pace that runner can reasonably expect to sustain.

When ‘watch and wait’ works best
Harvard researchers have found that as many as 50 percent of young girls treated for germ cell ovarian tumors might be spared chemotherapy using a “watch and wait” strategy to determine if the follow-up treatment is needed.
-
Smelling the light
Harvard neurobiologists have created mice that can “smell” light, providing a new tool that could help researchers better understand complex perception systems that do not lend themselves to easy study with traditional methods.

Mapping the road to obesity
Unlike previous investigations, which examined fat cells at a single static time point, this new study mapped several histone modifications throughout the course of fat cell development. With these new findings researchers now have a better understanding of normal fat cell development, and going forward, they can compare normal fat cells with fat cells in disease states.
-
Progress on obesity
Researchers have identified 18 gene sites associated with obesity and 13 associated with body fat distribution, helping to unravel the riddle of obesity.
