Megalodon shark gave live birth to large newborns that likely grew by eating unhatched eggs in womb
A new study shows that the gigantic Megalodon or megatooth shark, which lived nearly worldwide roughly 15-3.6 million years ago and reached at least 50 feet (15 meters) in length, gave birth to babies larger than most adult humans.
Magee-Womens Research Institute Opens Applications for $1 Million Prize
The $1 million Magee Prize will support a collaborative team whose groundbreaking research in reproductive sciences and women’s health could improve lives globally.
Split Ends: New studies show how DNA crossovers can drive healthy, abnormal sperm, egg cell division
Human genetic diversity wouldn’t be possible without DNA crossovers in egg and sperm cells. Two Harvard Medical School studies provide new insights into how crossovers go right–and wrong, leading to infertility, miscarriages and birth defects.
Human pregnancy is weird. A new study adds to the mystery
University at Buffalo and University of Chicago scientists set out to investigate the evolution of a gene that helps women stay pregnant: the progesterone receptor gene. The results come from an analysis of the DNA of 115 mammalian species.
How Sperm Unpack Dad’s Genome so it Can Merge with Mom’s
UC San Diego researchers discover the enzyme SPRK1’s role in reorganizing the paternal genome during the first moments of fertilization — a finding that might help explain infertility cases of unknown cause.
Random gene pulsing generates patterns of life
A team of Cambridge scientists working on the intersection between biology and computation has found that random gene activity helps patterns form during development of a model multicellular system.
Small marsupials in Australia may struggle to adjust to a warming climate
Numerous questions remain unanswered as to how the planet’s species will respond to climate change.
Research sheds light on the evolutionary puzzle of coupling
A UTSA researcher has discovered that, whether in a pair or in groups, success in primate social systems may also provide insight into organization of human social life.
