Blood is thicker than water – and blood plasma is, too Posted: 18 Feb 2013 06:25 AM PST Blood flows differently than water. Anyone who has ever cut themselves knows that blood flows viscously and rather erratically. The similarity between blood and ketchup is something not only filmmakers are aware of. Experts refer to these materials as "non-Newtonian fluids," of which ketchup and blood are prime examples. These fluids have flow properties that change depending on conditions, with some becoming more viscous, while others become less viscous.

'Activating' RNA takes DNA on a loop through time and space Posted: 17 Feb 2013 10:42 AM PST Long segments of RNA -- encoded in our DNA but not translated into protein -- are key to physically manipulating DNA in order to activate certain genes, say researchers.

Horse meat scandal: Experts views from across Europe Posted: 17 Feb 2013 05:37 AM PST It all started when the Irish Food Standard Authority realized, mid-January, that some of the burgers sold in the country (and in the UK) contained about 29% of equine DNA, upon testing. This was much more than could not be accounted for by cross contamination in a meat factory. Tracing the meat back through complex supply chain, the manufacturer pointed the finger at a meat producer in Poland. At the time of writing, this possible source of contamination has not been confirmed. Doubt remains, particularly because Ireland has been known for poor traceability of its own horse meat aimed at export, which was found to have falsified passports.

Is there a Neanderthal in the house? Posted: 17 Feb 2013 05:29 AM PST As we humans evolved over the millennia to walk on two legs, grow larger brains and shorter jaws, bear big babies and live longer, we've also experienced some negative consequences. But keeping our evolutionary history in mind can help us better deal with issues from obesity to difficult childbirth in a much more productive way, according to an anthropologist.
