A popular aquarium fish may hold answers to how tumors form in a childhood cancer.

Muscle precursor cells called myoblasts are formed during normal fetal development and mature to become the skeletal muscles of the body. Rarely, a genetic error in which pieces of two chromosomes fuse together occurs in a cell related to this process and triggers those cells to multiply and behave abnormally. A particularly aggressive form of the muscle cancer rhabdomyosarcoma results.

Pilot study results indicate that a sleep and yoga intervention has promising effects on improving sleep disturbance, sleep-related impairment, and sleep health behaviors.

If you’re up there in age and feel like you can coast as a couch potato, you may want to reconsider. A new study suggests, for the first time in women over age 70, that working up a sweat can reduce the influence one’s genes have on obesity.

MIT researchers, working with scientists from Brigham and Women’s Hospital, have developed a new way to power and communicate with devices implanted deep within the human body. Such devices could be used to deliver drugs, monitor conditions inside the body, or treat disease by stimulating the brain with electricity or light.

Asthma and respiratory viruses don't go well together. Weakened by the common cold or the flu, a person suffering an asthma attack often responds poorly to emergency treatment; some must be hospitalized. This is especially true for preschoolers.

In a new study, researchers at Uppsala University and other institutions have identified genetic material from the recently identified Alkhurma hemorrhagic fever virus in the tick species Hyalomma rufipes. The discovery was made after thousands of ticks were collected from migratory birds captured in the Mediterranean basin. The results indicate that birds could contribute to spreading the virus to new geographical areas.

What would happen if all petrol and diesel-powered vehicles were removed from a smaller European city? Up to 4% of all premature deaths could be prevented, according to a new study from Lund University in Sweden. The researchers used Malmö, Sweden, as a case study to calculate the health costs of inner city traffic.

New research from Northumbria University has revealed that metal-related pollution began in the Balkans more than 500 years before it appeared in western Europe, and persisted throughout the Dark Ages and Medieval Period, meaning the region played a far bigger role in mineral exploitation than previously believed.

A specialized fat molecule, called cardiolipin, that is made within the body's own fat cells, is far more significant to the body's overall state of health than previously realized.

A forthcoming study of northern India suggests that people living in rural areas are as likely to die prematurely from the effects of poor air quality as those living in cities. The study found that the sources of pollution in urban versus rural communities may be somewhat different, but the results are the same: high mortality linked to circulatory and respiratory problems.  Air-pollution studies tend to focus on big cities, yet some 70 percent of India’s population dwells in rural areas, so the research may have wide implications.
