A new study shows how interbreeding of modern humans and Neanderthals boosted our genomes.
- Homo Sapiens mated with Neanderthals when they left Africa for Eurasia.
- Neanderthals developed key genetic adaptations to fighting diseases.
- Modern humans have 152 genes inherited from the Neanderthals that interact with viruses.
If you want to know what makes a Canadian lynx a Canadian lynx a team of DNA sequencers has figured that out.
- A team at UMass Amherst recently sequenced the genome of the Canadian lynx.
- It's part of a project intending to sequence the genome of every vertebrate in the world.
- Conservationists interested in the Canadian lynx have a new tool to work with.

Cross-breeding with bobcats in some portions of the lynx's habitat also represents a challenge to the lynx's genetic makeup. The two themselves are also linked: warming climates could drive Canadian lynxes to cross-breed with bobcats. </p><p>John Organ, chief of the U.S. Geological Survey's Cooperative Fish and Wildlife units, <a href="https://www.masslive.com/expo/news/erry-2018/09/e565d904646142/umass-scientists-oversee-first.html" target="_blank">said to MassLive</a> that the results of the sequencing "can help us look at land conservation strategies to help maintain lynx on the landscape."</p>
Scientists can now virtually reconstruction certain long-dead individuals, without the need for DNA samples from physical remains.
Find the right genes and we’ll have a way to prolong life and good health, perhaps indefinitely.
Better food, healthcare, working conditions, and safety protocols have allowed humans to live longer and healthier than ever before. In most developed countries today, the average lifespan is 80 years, while in 1906, a little more than 100 years ago, it was 48. Projections moving forward look so good that there’s a debate in the medical community on whether or not we can increase human longevity indefinitely.
Researchers at Human Longevity have developed technology that can generate images of individuals face using only their genetic information. But not all are convinced.
What if a computer could generate a realistic image of your face using only your genetic information?
