POPSGot any nude photos of your baby? Shred them. Now! Several people, all of whom I'd objectively call "innocent," have been investigated by the FBI, humiliated, arrested, and effectively destroyed by scandal when photo-developing and computer-repair shops discovered that they had photographed their young children naked. One father lost custody of his kids for taking a photo of them mooning him. The argument is: "we all have to view innocent photos through the eyes of a pedophile, for the good of the children." Effing scary. I mean, I've taken several pictures of my son in the bathtub, and according to this article, that makes me effectively guilty of child pornography. Better take those shots off of Snapfish.com.

POPSImportant Comment made by "deadcowkid" to "Brain That Changes Itself" This is a very important comment by deadcowkid for the clip: 'Brain That Changes Itself" http://clipmarks.com/clipmark/378F24A4-D35D-43A7-9FF4-3C3BCF2C2CA5/ . I thank him for telling such an inspiring story. "He said the brain was misunderstood and capable of repairing itself. He told me to give it three good years".

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.

POPSHymens: Now Made in China In places where honor killings are practiced against women who can't prove they were virgins on their wedding nights, this little, seemingly innocuous sex toy has opened quite a can of worms.

POPSField Testing Third World Computers This is a very interesting experiment in access and education. The most interesting part is that the children are expected to fix the computers themselves! Actually, I learned a lot of stuff this way - by tinkering - but is it realistically applicable to all the kids? If it works, it will work brilliantly. It is certainly a new way of networking information. Maybe clipmarks should get in on something like this...

POPSStephen Hawking: "Humans Have Entered a New Stage of Evolution" We have entered a new phase of evolution. "At first, evolution proceeded by natural selection, from random mutations. This Darwinian phase, lasted about three and a half billion years, and produced us, beings who developed language, to exchange information." But what distinguishes us from our cave man ancestors is the knowledge that we have accumulated over the last ten thousand years, and particularly, Hawking points out, over the last three hundred.

POPSsteven wright's words 18 - Hard work pays off in the future, laziness pays off now. 20 - If Barbie is so popular, why do you have to buy her friends? 21 - Eagles may soar, but weasels don't get sucked into jet engines. 22 - What happens if you get scared half to death twice? 23 - My mechanic told me, "I couldn't repair your brakes, so I made your horn louder." 24 - Why do psychics have to ask you for your name? 25 - If at first you don't succeed, destroy all evidence that you tried. 26 - A conclusion is the place where you got tired of thinking. 27 - Experience is something you don't get until just after you need it. 28 - The hardness of the butter is proportional to the softness of the bread. 29 - To steal ideas from one person is plagiarism; to steal from many is research. 30 - The problem with the gene pool is that there is no lifeguard. 31 - The sooner you fall behind, the more time you'll have to catch up. .

POPSRadical Life Extension and Religious Evolution "Technology will inject competition into religion and force religious authorities to clarify what they mean by immortality." This is important, according to Cole-Turner because "there is currently a lot of evasiveness about what immortality means."

POPSThe Chaos Inside a Cancer Cell One of the rearrangements disrupts a gene called RAD51C which is involved in mending serious chromosome breaks, those in which both strands in the DNA are disrupted. The impairment of double strand break repair could be a major cause of all the other rearrangements, the researchers suggest.

POPSDoes the Milky Way Influence Earth's Biodiversity Cycles? Research Says "Yes" The boost in cosmic-ray exposure may have a direct effect on Earth's organisms, according to paleontologist Bruce Lieberman. The radiation would lead to higher rates of genetic mutations in organisms or interfere with their ability to repair DNA damage. In this way, the process could lead to new species while killing off others. If future studies confirm the galaxy-biodiversity link, it would force scientists to broaden their ideas about what can influence life on Earth. "Maybe it's not just the climate and the tectonic events on Earth," Lieberman said. "Maybe we have to start thinking more about the extraterrestrial environment as well."

POPSNew Discovery Could Rejuvenate the Brain “If we can target therapies that block this mechanism, then neurons should be able to sprout new connections, therefore stimulating the brain’s ability to repair its wiring network.” The research reveals that the loss of plasticity is due to the protein calpain actively blocking the protein cortactin, which is responsible for the sprouting of new connections. The researchers reduced calpain activity in animal models to unlock the sprouting potential of neurons and found that when calpain activity is reduced neural plasticity is enhanced.

POPSA Squirt of Stem Cell Gel Heals Brain Injuries
more: The donor cells often fail to grow or stimulate repair at the injury site, possibly because of the inflammation and scarring present there. The injury site also typically has very limited blood supply and connective tissue, which might prevent donor cells from getting the nutrients they require. Dr. Zhang's gel, however, can be loaded with different chemicals to stimulate various biological processes at the site of injury. In previous research done on rats, she was able to use the gel to help re-establish full blood supply at the site of brain injury. This could help create a better environment for donor cells. In a follow-up study, Dr. Zhang loaded the gel with immature stem cells, as well as the chemicals they needed to develop into full-fledged adult brain cells. When rats with severe brain injuries were treated with this mixture for eight weeks, they showed signs of significant recovery. The new gel could treat patients at varying stages following injury, and is expe
