In sex education videos the race of sperm to the egg is portrayed like an Olympic swimming final as sperm surge purposefully down the female reproductive tract to the finish line. The reality, however, may be rather less elegant...
The Oklahoma Supreme Court has declared void a ballot initiative that would have asked voters to expand the definition of a person in the state constitution to include human embryos and fetuses....
A gene identified in MRSA may contribute to the spread and virulence of the superbug. The gene - sasX - is located in a segment of DNA called a mobile genetic element and is capable of jumping from one bacterium to another...
Chemical alterations in a group of genes affect how we age, scientists have discovered. These changes switch genes on or off in response to diet or environmental factors throughout our lives. Researchers found that four genes that are epigentically switched off in later life may have a bearing on how well we age...
