This is a live image of the liver of a translucent, larval zebrafish. It was taken using confocal microscopy, which allows for clear images of the internal organs of a whole live animal. Quinlivan fed a fluorescently tagged fatty acid to a larval zebrafish and then photographed its liver at 400x magnification. The round dots

Salk scientists move one step closer to developing ‘exercise-in-a-pill.’ Partial view of a mouse calf muscle stained for different types of muscle fibers: oxidative slow-twitch (blue), oxidative fast-twitch (green), glycolytic fast-twitch (red).

WiGait uses wireless signals to continuously measure a person’s walking speed. Credit: Jason Dorfman, MIT CSAIL We’ve long known that breathing, blood pressure, body temperature and pulse provide an important window into the complexities of human health. But a growing body of research suggests that another vital sign — how fast you walk — could

Predicted probabilities of remission for each treatment at different levels of body mass index (BMI).

Examining new personalized and precision psychiatry approaches, a new study in Personalized

Considered a hormone rather than a vitamin, vitamin D is produced when skin is exposed to sunlight. Vitamin D receptors are found in virtually every cell in the human body. As a result, it plays a wide role in the body’s functions, including cell growth modulation, neuromuscular and immune function and inflammation reduction. Credit: ©

Scientists have demonstrated that HIV-1 replication can be completely shut down and the virus eliminated from infected cells in animals with a powerful gene editing technology known as CRISPR/Cas9. Credit: © gamjai / Fotolia A permanent cure for HIV infection remains elusive due to the virus’s ability to hide away in latent reservoirs. But now,

Slender faces are also associated with overbites and left-handedness. Credit: Courtesy of Philippe Hujoel Individuals with a slender lower face are about 25 percent more likely to be left-handed. This unexpected finding (abstract) was identified in 13,536 individuals who participated in three national surveys conducted in the United States. This association may shed new light
