Genetics and Genomics

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...

For children who suffer with Irritable Bowel Syndrome (IBS), the pain may not end there. A study of 992 children who suffered with abdominal pain-related disorders included 270 children with IBS, 201 with functional dyspepsia, and 311 with functional abdominal pain. Blood tests were performed on each participant of a study, with 15 positive results...

IBM recently announced that its Watson supercomputer, which grew to fame on the TV game show Jeopardy, will be teaming up with the New York Genome Center (NYGC) to help doctors develop personalized treatments for cancer patients based on their genetic makeup. Genetic information obtained though genome sequencing has the potential to help clinicians tailor treatment...

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...

The discovery of a 3,000 year-old human skeleton is proof that cancer is not a modern-day illness. Originally reported in the academic journal PLOS ONE, the discovery was made by a Durham University PhD student in a tomb in modern Sudan in 2013. The most complete skeleton this old with metastatic cancer dates back to...

Some species of birds have long been a mystery in their behaviors. Thanks to a discovery made by University of Akron researchers, there is now believed to be an explanation for how sea birds fly over 80,000 miles during their migration from the North Pole to the South Pole, and the Emperor penguin is able...

What would be a dream come true to many people has proven to be a reality in mice. An article in Science News reports on how mice have the ability to shed a gene, FAT10, to help them lose body fat. Even more amazing, those mice that dropped weight in this way were also shown...

Taking the command “stay!” to a new level has allowed scientists to learn new details of how dogs’ brains work. A science article reprinted in Science News, Science Daily and other current science news publications was originally reported in the scientific journal Current Biology on February 20th giving details of the study where researchers taught...

  Everyone is familiar with pain, but no one fully understands its underlying molecular mechanisms. Scientists at King’s College, London, are doing something about that. In a recent study they found that life style and environmental factors that affect the epigenome, such as diet, smoking, drinking and exposure to pollution, might also alter a person’s sensitivity...
