Researchers at Tel Aviv University have determined that certain beverages alter the length of the copy and repair accessories at the ends of our DNA, known as telomeres. Although the role of telomeres is not completely understood it is believed shorter telomeres are associated with cancer risk (doi: 10.1002/ajhb.21127). The Tel Aviv researchers studied yeast that has many of the same genes as humans. They identified 400 genes that work together to determine telomere length. Many environmental stresses were imparted on the genes with no effect on telomere length. However, when the genes were exposed to a low concentration caffeine they shortened and when they were exposed to alcohol they lengthened (doi: 10.1371/journal.pgen.1003721).
My poor little telomeres must be exhausted, yo-yo’ing between the coffee induced shortening of the morning and the alcohol encouraged lengthening of the evening. But, hey, at least it all balances out.
I read about this research at Science Daily. Check it out!
Are you a gymnast? If so you most likely have 6 times the concentration of fire retardant chemicals in your blood than the general public – a rate of exposure on par with carpet installers. The source? All the foam that cushions your landing.
Epidemiologist and exposure scientist Counrtney Carignan is a post doc at Dartmouth College, she was also at one time a competitive gymnast. Her graduate work on flame retardants got her curious about the risk of pentabrominated diphenyl ether exposure in the gym environment. The chemical has been banned as a retardant in the EU since 2005 because it causes health issues. Carignan found that air samples taken in training facilities measured up to three orders of magnitude higher for PentaBDE than in a residential environment.

The image above shows a few of the 100,000 turbine blades squeezed onto a disk about a centimeter wide. The turbines run the world’s smallest vacuum pump, part of the tiniest mass spec imaginable. The device, created by Honeywell, could be equipped for your smart phone and continuously measure the quality of air you breathe. A Honeywell scientist says,
"One thing we are very excited about is putting these into smartphones, essentially adding a sense of smell that can sense everything from toxic chemicals to pollen to general air quality," Yang said. "They could keep a cumulative record of exposure for every person carrying one, noting when and where a user was exposed."

Meet Siphopteron species 1. It’s a species of sea slug, recently discovered by Rolanda Lange. To procreate, two members of the species get together, stick organs into each other’s heads, and fertilize. That’s right — nature has at last provided us with a perfect example of the mindfuck.
Dear god! Why did I have to see this?
