Early hominins were known to have cross-bred when they crossed paths, and now the most direct evidence of those meetings has been found. By sequencing the genome of a hominin bone from a Siberian cave, anthropologists have discovered the direct descendant of a Neanderthal and a Denisovan.

The further back in time you go, the patchier our understanding of life on Earth gets. Now, British scientists have used a different method known as a molecular clock to plot out a rough timeline of all life on Earth, tracing the first organisms back to about 4.5 billion years ago.

A new study is offering an exciting new clue into the origins of autism spectrum disorder finding a single dysfunctional protein may be responsible for coordinating expression in all the genes that are known to result in autism susceptibility.

Containment measures are in development to keep GMOs from escaping and potentially disrupting natural ecosystems. To that end, researchers have now conducted a multi-year study using GMO poplar trees and found that engineering them to be sexually sterile is an effective containment measure.

We may be a step closer to new treatments for cystic fibrosis, as two research teams are now reporting the discovery of a new type of cell in the airways. These rare cells seem to be where most activity of a certain gene is located, mutations of which are known to cause cystic fibrosis.

An intriguing new study from Columbia University Irving Medical Center has found that the same gene associated with a condition responsible for autoimmune-related hair loss could be recruited to help our immune cells better target tumors.

To investigate how gut bacteria can affect overall health, researchers at Harvard Medical School have deleted a single gene from one gut bacteria species and found that it alters the metabolism of the host, reducing their weight gain.

A new research paper has again raised doubts over the safety and accuracy of the CRISPR-Cas9 gene editing technique. The study suggests that the gene editing process can cause extensive unforeseen and unpredictable alterations to DNA sequences outside of the intended targets.

The CRISPR gene editing revolution is less than a decade old and scientists are still learning how best to deploy this ground-breaking technique. A team has recently discovered why the technique sometimes fails, uncovering a novel insight that will hopefully make future research more efficient.

The way genes are expressed can be changed by environmental or lifestyle factors and these changes may be inherited from parents. A new study has found that male mice who spend time in cold environments may pass down this “experience” to their kids, in the form of higher levels of warming brown fat.
