New Study Sheds Light On Two Regions of DNA Linked to Male Homosexuality

There is little doubt any more among the research community that sexual preference is a combination of both nature and nurture. In other words, it comes about because of both genes and the environment. The next questions to answer have more to do with how much each contributes and which genes and environmental factors are involved.

Some of Us May Have a Genetic Predisposition to Disliking Exercise

About 90% of us over the age of 12 fail to get as much exercise as we should. This is almost certainly not because we don’t believe in those benefits. Instead, it looks like at least part of the reason may be that some of us are genetically programmed to hate exercise.

Surprising Amount of Neanderthal DNA Still Evident in Modern European and Asian Populations

Neanderthals may be extinct but at least 20-40% of their DNA lives on in modern Europeans and Asians because of interbreeding. Neanderthal DNA survives because it gave useful traits to the ancestors of Europeans and Asians.

Another Step Closer to Redesigning Life: Scientists Create Synthetic Chromosome in Yeast

A group of scientists has replaced a natural chromosome in yeast with an artificial one. This won't only make a more useful yeast, but it also opens the door to redesigning the DNA of more complicated beasts like plants and animals (or us) and maybe even to resurrecting extinct species like the passenger pigeon or wooly mammoth.

How Damaged is Your DNA? A New Startup Wants to Know

If your annual checkup included a simple blood test to determine how much DNA damage you have in your body, you may be able to optimize your long-term health by taking action to minimize DNA damage due to your diet, exercise and environment. A startup company called Exogen Biotechnology wants to provide the public with a way to monitor their DNA health.

Click to “Like” My Genome: Part Two

The FDA challenge may hurt the personal genetics industry in the short run. No traits, no health risks -- no fun. But the company is still allowed to show ancestry results. 23andMe's map of my distant relations offered a glimpse of the movement of people across the world. The more people who joined and shared their genomes, the more comprehensive a picture we could form of a global family tree. A day might come when I would know precisely how related I was to, for example -- you.

Why Are So Many People Right-Handed? Genetic Research May Hold The Clues

Scientists have struggled for a long time to explain why 85-90 percent of people are right-handed. They’ve known genetics plays an important role in people occasionally ending up left-handed, but they also know it is not the whole story.

Who Wins and Who Loses With the Supreme Court’s Gene Patenting Decision?

A US Supreme Court ruling issued Thursday has big implications for Bay Area biotech companies and medical researchers, not to mention patients who want genetic testing or gene-based therapies. The Justices ruled that no one has the right to patent natural human genes, but synthetic DNA material can be patented.
