After looking at a database of 850 patients diagnosed with lymphatic and bone marrow cancers between 1972 and 1980, researchers from the University of Tasmania and Britain‘s Bristol University found that living near high-voltage power lines might increase the risk of leukemia, lymphoma, and related conditions later in life.

People who lived within 328 yards of a power line up to the age of five were five times more likely to develop cancer. Those who lived within the same range to a power line at any point during their first 15 years were three times more likely to develop cancer as an adult.

Compared to newborns conceived traditionally, newborns conceived through in vitro fertilization (IVF) are more likely to have certain chemical modifications to their DNA, according to a new study. The changes involve DNA methylation -- the binding of compounds known as methyl groups to DNA -- which can alter gene activity. Only one of the modifications was seen by the time the children were 9 years old.

Scientists have looked at understudied human populations from the South Pacific, which are severely affected by a variety of diseases, including vector-borne infectious diseases such as Zika virus, dengue, and chikungunya, and metabolic diseases such as obesity and diabetes. Using genome sequencing of 320 individuals, the scientists have investigated how human populations have biologically adapted to the environments of the Pacific islands and how this has affected their current state of health.

Researchers have discovered how a uniquely high density of sweat glands evolved in the human genome. Researchers showed that the higher density of sweat glands in humans is due mostly to accumulated changes in a regulatory region of DNA -- called an enhancer region -- that drives the expression of a sweat gland-building gene, explaining why humans are the sweatiest of the Great Apes.
