Neanderthal viruses found in modern humans Posted: 19 Nov 2013 08:04 PM PST Ancient viruses from Neanderthals have been found in modern human DNA. Researchers compared genetic data from fossils of Neanderthals and another group of ancient human ancestors called Denisovans to data from modern-day cancer patients. They found evidence of Neanderthal and Denisovan viruses in the modern human DNA, suggesting that the viruses originated in our common ancestors more than half a million years ago.

Origin of species: Protein imbalances doom hybrids Posted: 19 Nov 2013 08:25 AM PST Why do crosses between closely related species fail to produce fertile hybrids? A new study shows that differences in the levels - not necessarily the sequences - of certain key proteins are crucial in mediating reproductive isolation. Two individuals are defined as belonging to the same biological species, if matings between them give rise to viable and fertile offspring. Crosses between closely related, but already distinct, species produce hybrid offspring that are either inviable or sterile, and thus cannot give rise to a self-propagating hybrid lineage.

They determined that red LED light promoted growth and that blue LED light was good for phenolics accumulation rather than growth, thus concluding that a combination of red and blue light is essential for cultivation of leafy vegetables like lettuce.

New technique controls dimensions of gold nanorods while manufacturing on a large scale Posted: 19 Nov 2013 07:10 AM PST Researchers have developed a technique for efficiently producing nanoscale gold rods in large quantities while simultaneously controlling the dimensions of the nanorods and their optical properties. The optical properties of gold nanorods make them desirable for use in biomedical applications ranging from imaging technologies to cancer treatment.

Recreating the history of life through the genome Posted: 19 Nov 2013 07:10 AM PST One of the most important processes in the life of cells is genome replication. In most organisms genome replication follows a set plan, in which certain regions of the genome replicate before others; alterations in the late replication phases had previously been related to cancer and aging. Now, scientists have, for the first time related this process to evolution of life.
