Fascinating: Many of us have genes from Neanderthals
One way or another many human beings carry a percentage of their DNA inherited from Neanderthal man. This has been suspected for some time (not only in comedy routines); now there is genetic data to back it up. An international team of scientists coordinated at the Max Planck Institute of Evolutionary Anthropology (Leipzig, Germany) and [...]

A new layer of genetic information: DNA sub-code
To some it sounds like something out of a spy story – sub-codes within the genetic code. Ah the hidden code; Dan Brown would be proud of the discovery. The actual discovery is perhaps not so thrilling, but potentially much more important than novelistic entertainment. Two researchers, Professor Yves Barral (ETH Zurich, Switzerland), and Dr. [...]

Disease linked genes have environmental factors too
Within the human body there are few diseases that aren’t influenced by some kind of environmental factors (stress, obesity, smoking, lack of sleep). Put another way, even diseases that have a genetic link (cancer, heart disease, diabetes) are not fully explained by genetics – environmental factors also play a role. Teasing apart the ‘who does [...]

There’s more to gene expression than biochemistry
At a guess, ninety-nine percent of biologists’ attention to DNA and gene expression is based on biochemistry. That’s good, since the biochemistry is obviously important and difficult enough to analyze. However, there is something else – it’s called physics. Cells, cell components, and DNA all exist in the physical world and therefore are also affected [...]

Formerly, one brain cancer…now it’s four
One of the things that makes cancer so difficult to ‘cure’ is that it has so many forms. Perhaps most difficult of all, as scientists are learning, are cancers such as the most common and usually fatal brain cancer glioblastoma multiforme (GBM). As a new study at the University of North Carolina (Chapel Hill, USA) [...]

Stapling peptides to drug the undruggable
Turning specific genes on and off is something Nature does routinely. Not so for scientists. In particular, a class of proteins that control whether certain genes are activated or not, so called transcription factors, have been considered unreachable. Because of their complex folded configurations, transcription proteins are highly resistant to modification and have been considered [...]
