"Epigenetic Changes Programmed Into Future Generations But the most disturbing finding was that atrazine had epigenetic effects. Epigenetics is the theory that environmental factors, such as diet, lifestyle choices and pesticides can impact the health of people who are exposed to them and also their descendants. Human DNA, according to epigenetics, is not unchangeable; it can be altered by such environmental factors. Epigenetic changes can be imprinted on the DNA of a fetus during pregnancy according to Winchester."

The massive blast of Siberia-like cold that is wreaking havoc across North America is proving that if we humans want to keep surviving frigid winters, we are going to have to keep burning natural gas - and lots of it - for decades to come.

The use of the polymeric flame retardant PolyFR in "eco-friendly" foam plastic building insulation may be harmful to human health and the environment, according to a new commentary in Environmental Science & Technology. The authors' analysis identifies several points during the lifecycle of foam insulation that may expose workers, communities, and ecosystems to PolyFR and its potentially toxic breakdown products.

Unlike Chess, where the objective is to expose and capture the King by eliminating pieces, in Go the objective is to capture territory by surrounding enemy pieces, called stones, and by protecting unclaimed area.
