POPSLearning, how we learn "Flies where the well-known group of learning genes had been manipulated failed miserably in the first to experiments. However, in the third experiments, they learned even better than normal flies." "“Our studies show that the prominent learning genes are not playing any role in purely behavioral learning. Our results suggest that Pavlovian learning somehow suppresses behavioral learning.”

POPSAraucana Chickens Just thought some of you might be interested in this rather unusual breed of chicken, among others, we have here on the tundra.

POPSExtinct thylacine genome brought to life Known as the Tasmanian Tiger, it was one of the few marsupial predators that were in Australia before the arrival of the west. The other is the Tasmanian Devil, which survives, but is threatened by a disease that causes ulcers.

POPSRoyal jelly triggers queen genes I'm sure any beekeeper can tell you that a queen bee is just a worker that has been fed royal jelly, They wanted to study the process in more detail, because the principle is thought to work in other animals, including humans, and they were also trying to work out how to make 'clean' queens in an attempt to help repair the damage to the honey industry with what has become affected by something known as Colony Collapse disorder. They achieved the same results as royal jelly when they switched of a gene Dnmt3, which showed demetylization of DNA led to the development of certain traits. Studies continue, but in humans things like obesity,infertility, longevity, and brain disorders, are thought to be affected by the chemical effects on genes

POPSOne Computer Could Run Entire Internet Hard to imagine how this is possible, and it seems counterintuitive to think of the Internet as a single computer. But it fits with the strange trend that's underway: After becoming more and more distributed, computing is again becoming more and more centralized, with thin, simple nodes at the edge and massive hardware at the core.

POPSChoose your eye-color personality Eyes are the window to the soul."No matter what your eye color is, you will have stereotypes that come along with them.You were born with your natural eye color for a reason.Your eye color is unique and fits your personality so do not change a thing." Green eyes are definitely the sexiest of all eye colors :-)

POPSBrainbow? Intriguing pictures, however the article leaves me wondering where the scientists are going with this. I hate to think the project was just to create colorful pictures.

POPSScientists 'color the wiring,' for brain mapping Scientists have grafted a gene that causes florescence into mice, and make only their neurons glow. They are learning to trace neural messages along the pathways. This can be used to gain understanding of the physical aspects of the connections and the traces, that are characteristic of diseases like autism, mental retardation, and bipolar disorders

POPSImagine the Possibilities
BRUCE BRYAN, a surgeon, and Gene Finley, an oncologist, think they may have a new weapon in the war against cancer. It's a squirt gun. Not just any squirt gun, mind you. Theirs shoots glow-in-the-dark water. They've also created luminescent cake frosting, radiant hair mousse and greeting cards with lettering like neon. "Watch this," says an associate in a lab coat, swallowing a beaker full of glowing soda pop. "It's protein. Totally harmless!"Dr. Finley landed on the faculty of the University of Pittsburgh Medical Center and in an oncology practice at the V.A. hospital here, where he studies the genetics of colon cancer. Dr. Bryan, meanwhile, made some money in real estate, quit his surgery practice in Arizona, began doing pro bono medicine in the Dominican Republic and adopted a low-overhead lifestyle aboard a houseboat. ONE EVENING during a power outage , Dr. Bryan opened a beer. Wouldn't it be cool, he thought, if the beer glowed? And so it began! Read about it, very cool!

POPSGroup renames Asteriod for George Takei Ensign Sulu, from Star Trek.( I'm sure he was an admiral in the movies.) Asteroids are generally cataloged, and given a catalog number. Some Asteroids are then renamed after famous, or notable people. They mention websites that offer naming rights to stars. These names are not generally used by astronomers, while the Asteroid names given by the International, Astronomical Union are.

POPSOne man's genes show the mystery of DNA
Looks like another reason to prohibit copyright. The effect described in the registration of a discovered, or artificially introduced gene, may be dramatically different with each individual. Those seeking copyright, have neither the concern, the understanding or the ability to deal with consequences that are yet beyond us. There should also be note taken in genetic research in other species. Where remarkable differences are seen in human DNA that were unimagined, so genes across species should be given more complete investigation, before the results can be considered applicable to humans. We are still too proud of our acquired knowledge, to remember often enough that we know so little of genetics. That being one of the primary means of reproducing, and regenerating life, we will continue to be surprised by what we find, and will be continually rewriting our textbook. One other question. If we did manage to master our own DNA what would we do with it ?
