POPSHuge hidden biomass lives deep beneath the oceans They found simple organisms known as prokaryotes in every sample. Prokaryotes are organisms that often have just one cell. Their peculiarity is that, unlike any other form of life, their DNA is not neatly packed into a nucleus.

POPS'bizarre mix of mammal, bird and reptile, with very complex sexuality' The fact that the animal has five X and five Y chromosomes is "the weirdest thing about a very weird animal," said Ewan Birney, a co-author on the paper, based at the European Bioinformatics Institute, near Cambridge. "In theory it means there are 25 possible sexes, though in practice that doesn't happen."

POPSFive Reasons Why Aliens Will Make Contact with the Japanese First North Korea is rumored to have recently released a statement claiming that their nuclear reactor has the dual capability of communicating wirelessly with alien species up to 1,000 light years away in real time. Of course, we can't believe everything that the North Korean government says, but seriously, I wouldn't be surprised at all if they were already communicating with other planets. If that's the case, it should be relatively easy for Japan, a neighboring country, to intercept their signals with laser pulses and let the world know definitively what Kim Jong Il has known for decades—that there is life beyond Earth.

POPSLab Freaks Gone Wild? “What was once only science fiction is now becoming a reality, and we need to ensure that experimentation and subsequent ramifications do not outpace ethical discussion and societal decisions.

POPSWill Alabama execute an innocent man? I cannot comprehend why they refuse to do this simple test. Are they so fearful of having made a mistake that they would prefer not to administer the test? If they are sure they are right, why not administer the test just so they can say "I told you so"

POPSMan Made Life Whoa. The implications from this will be enormous. If this project succeeds expect a concerted campaign of denial and attack from the religious conservatives.

POPSWill "Th!nk" Ignite an Electronic Car Revolution in the U.S.? Think City is one of two models that are out already, together with the Think Ox, with a choice of either lithium or a sodium battery, it's range is enough to take a suburban dweller to the downtown office and back, with zero carbon footprint. The car is thoughfully fully computerized and allows a key-less entry. It features real time navigation, web, e-mail and open source interfaces, intelligent and sustainable driving and route calculations. The DNA-key gives the user feedback on charging status and sends messages, for example, for pre-heat or pre-cool options via GPRS. Pricing has yet to be announced, but the company's current vehicles cost less than $25,000.

POPSOur Genome Changes Over Lifetime, And May Explain Many 'Late-onset' Diseases They found that in almost one-third of individuals, methylation changed over that 11-year span, but not all in the same direction. Some individuals gained total methylation in their DNA, while others lost. "What we saw was a detectable change over time, which showed us proof of the principle that an individual's epigenetics does change with age,"

POPSThe DNA Mystery: Scientists Stumped By "Telepathic" Abilities Even so, research published in ACS’ Journal of Physical Chemistry B, shows very clearly that homology recognition between sequences of several hundred nucleotides occurs without physical contact or presence of proteins. Double helixes of DNA can recognize matching molecules from a distance and then gather together, all seemingly without help from any other molecules or chemical signals. This recognition effect may help increase the accuracy and efficiency of the homologous recombination of genes, which is a process responsible for DNA repair, evolution, and genetic diversity. The new findings may also shed light on ways to avoid recombination errors, which are factors in cancer, aging, and other health issues.
