From Hannah Lachance (just before she headed right back up to UVM: An article in the April issue of Science News discusses the study of a gene that prevents mice from gaining weight even when on a high intake rich diet. Mice with this gene can eat as much as they want and they remain skinny even though they eat more and exercise less than the control group of mice which don’t have this gene and don’t have any ancestors that have this gene. The mice that are prone to obesity can have the DNA containing this gene injected successfully; they can eat as much as they want and they will not become obese. Researchers discovered that mice who don’t pass this gene on to their off-spring still have decedents up to 3 generations later that exhibit the effects of the gene. This is currently being explained by saying the gene passed on a “ghostly imprint” which is causing the effects to persist. Researchers aren’t exactly sure how this is occurring but they think it might in part be due to a change in the way that small pieces of RNA regulate protein production.

A team from NASA is claiming to have found nucleobase-like molecules on a meteorite. They also claim that their signal (unusual nucleobase analogs to include 2,6-diaminopurine) is well above background and is not found in terrestrial controls. As much as I want to implicitly trust this data, my experience with NASA biochemistry is that they shoot first and think/ask questions later. But the one thing they do better than anyone else: crow about it.

Too cool. I might be letting people know a little too much about me by admitting that I’ve watched it twice and it motivates me to knock out bench work.
