With the Genetics and Genomics 2016 virtual conference now on demand, we are extending the genetics conversation into this month with a new infographic. Epigenetics has been in the news quite a bit lately as researchers have been able to learn more about its process and influences. It turns out that epigenetics is an ever-changing...

Dog lovers would be the first to agree that these faithful companions know when their human friends are happy or sad.

While not normally thought of as a dodgy character, the sea trout, a distant cousin of the Norwegian Salmon has a lot of secrets. Researcher Jan G. Davidson and his graduate students are on the case and trying to decipher the development and habits of the sea trout and in the process hopefully discover why...

Many research studies have shown that what we look like affects what other people think of us and can influence our material well-being. Some of these findings are not very surprising. Tall people make more money than shorter people. Blonde women can have an advantage over other women even if they have less education.  The...

Foraging for food and the challenges that come with it has been recognized as important in shaping brain evolution in primates. New research from Washington University in St. Louis suggests that having to figure out how to survive on difficult to find bugs in the ground and forest could have helped us develop bigger brains...

The male-sex defining Y chromosome, has only 19 of the approximately 600 genes it once shared with the female-defining X chromosome over 200 million years ago, making it much smaller than the X and our 21 other chromosome pairs. In fact, the Y has so few genes left that there was some concern that the...

Throughout the history of high-altitude mountaineering in the Himalayan region, Sherpa have served as guides. And while the term ‘Sherpa’ has come to mean almost any guide or porter hired for a climbing expedition, the Sherpa are a distinct ethnic group that lives mainly in the country of Nepal. Among the international climbing community, Sherpa are...

Not that there are many reasons for improving the efficiency of reproduction in cockroaches, but a new study has determined that nothing beats a gentle touch to get the process in high gear. Researchers at North Carolina State University used duck feathers as artificial antennae to determine whether their touch could speed up reproduction in...

Fruit flies have long been used for all types of studies. Many species exist, and only one has been identified as being a crop pest. Researchers from the University of California recently explained the similarities and crucial differences between this species and the others. They also expanded on the idea of why another close relative...
