Genetics and Genomics

Welcome to the New Year! For LabRoots, the New Year brings the launch of our new Trending newsletter by category! Beginning in January, the Trending newsletter will get a face-lift. Our general Trending newsletter will still be coming to you two days per week. In order to offer you added information and news on the...

Scientists have found people’s genes haven’t retained as many fragments of viral DNA as other mammals, maybe due in part to our adoption of tools in lieu of teeth during conquest. Thus, exposure to viruses lurking in the blood may have been lessened. This is not to say people don’t harbor bits of DNA from viruses...

Autoimmune diseases that affect millions of people—including  type 1 diabetes, multiple sclerosis, rheumatoid arthritis,  and asthma—which mystifyingly cause the immune system to damage tissues in our bodies, may harbor a complex genetic component, a new study finds. This discovery could prompt better diagnosis and someday, better treatment options. A team of scientists from UC San Francisco,...

Given my sister’s history, I often wished she had Down syndrome. I’m sure that sounds odd, but when I was a kid, not to me. Jill was found to have Cornelia de Lange Syndrome (CdLS), a genetic disorder that bestows odd facial features and a small head, small stature, profuse body hair, heart problems, difficulty with...

Researchers seeking a cure for Type 1 diabetes may be a giant step closer to the prize. For most people with this chronic condition, the immune system goes awry, destroying insulin-producing (islet) cells in the pancreas. When a substantial number of these cells are wiped out, little or no insulin is produced. With no insulin to...

Those drawings your preschooler did that are hanging on the refrigerator may predict how many A’s might appear on his or her middle school report card. A study published in Psychological Science found that the accuracy of a child’s observational skills as demonstrated by their drawings is tied directly to their level of intelligence in...

Edward B. Lee, M.D., Ph.D, an assistant professor of Pathology and Laboratory Medicine in the Perelman School of Medicine at the University of Pennsylvania in Philadelphia, has received a three-year Clinical Scientist Development Award (CSDA) for $486,000 from the Doris Duke Charitable Foundation to support his research in frontotemporal lobar degeneration and amyotrophic lateral sclerosis...

Despite constant efforts to fight it, over 200 million people still contract malaria each year and an estimated 627,000 die from it, with most of the deaths occurring among children living in Africa. A vaccine would go a long way to controlling the problem and eventually even eradicating the disease. Although progress has been made,...

While all living organisms inherit mitochondria from their mothers, the father’s mitochondria are destroyed at the time of fertilization. Special cellular vesicles that originate in female fruit flies’ egg actively seek out and destroy the father’s mitochondria, according to research conducted by Dr. Eli Arama and a team in the Weizmann Institute’s Molecular Genetics Department. In...

It’s been known for a long time that when animals drastically decrease their calorie intake, they can avoid many age-related health problems and live for a much longer time. But, using this approach to extend human lives is questionable. For one thing, scientists still have not proven the benefits of calorie restriction in humans and...
