Researchers have reconstituted a viral genome from centuries-old caribou feces frozen in the subarctic, and they’ve used the ancient viruses to infect lab plants. The findings, published in Proceedings of the National Academy of Sciences this week, offer a rare glimpse of viral evolution.

An unfortunate side effect of aging is often decreased memory function. Age-related memory decline is linked to the dentate gyrus region of the hippocampus, which is a different part of the brain than the one affecting people with early Alzheimer’s or other neurodegenerative disease. A team of researchers have found that increasing dietary cocoa flavanols can improve brain function in this region, and even lead to better scores in memory tests.

Astronomers have captured time-lapsed images of an expanding thermonuclear fireball from a nova that erupted last summer. This is the first time a nova -- which is basically a stellar H-bomb -- has been imaged as the nuclear blast was happening. Observations of this early fireball stage, described in Nature this week, paint a far more complicated picture than simple models previously predicted.

Using just a couple spoonfuls of blood, scientists have grown functioning blood vessels in a dish in just seven days. Amazingly, doctors then successfully transplanted the vascular grafts into three children for bypass procedures. Now that the safety and feasibility of this speedy procedure has been established, medics can start using the technique as a novel way to treat patients with vascular diseases across the globe, which affect some 25 million individuals worldwide.

Researchers from the Salk Institute have discovered a previously unknown component of HIV’s life cycle that’s crucial to drive the production of new viral particles inside infected cells. Because it plays such an essential role in the virus’ replication process, the discoverers believe that targeting it could present a novel way to stop the virus from making new copies of itself. The work has been published in Genes & Development.
