+ - NASA proposes "water world theory" for origin of life

Submitted by William Robinson
William Robinson (875390) writes "A new study from researchers at Nasa's Jet Propulsion Laboratory has proposed the "water world" theory as the answer to our evolution, which describes how electrical energy naturally produced at the sea floor might have given rise to life. While the scientists had already proposed this hypothesis called "submarine alkaline hydrothermal emergence of life" the new report assembles decades of field, laboratory and theoretical research into a grand, unified picture."

+ - Organ regenerated inside a living animal for the first time->

Submitted by ananyo
ananyo (2519492) writes "Scientists at Edinburgh University have successfully persuaded an organ to regenerate inside an animal. As they report in the journal Development, they have treated, in mice, an organ called the thymus, which is a part of the immune system that runs down in old age. Instead of adding stem cells they have stimulated their animals’ thymuses to make more of a protein called FOXN1. This is a transcription factor (a molecular switch that activates genes).
The scientists knew from earlier experiments that FOXN1 is important for the embryonic development of the thymus, and speculated that it might also rejuvenate the organ in older animals. They bred a special strain of mice whose FOXN1 production could be stimulated specifically in the thymus by tamoxifen, a drug more familiar as a treatment for breast cancer.
In one-year-olds, stimulating FOXN1 production in the thymus caused it to become 2.7 times bigger within a month. In two-year-olds the increase was 2.6 times. Moreover, when the researchers studied the enlarged thymuses microscopically, and compared them with those from untreated control animals of the same ages, they found that the organs’ internal structures had reverted to their youthful nature."

That's nothing.

There is web site of Indian Railways. To book a ticket, they need your name, address, telephone number, blood group, blood sample, retina scan, tongue sample, sperm sample and name of your first born son, your great grandparents and names of all teachers who have taught you in past.

I said, no thank you.

+ - New black holes found in Andromeda

Submitted by William Robinson
William Robinson (875390) writes "Astronomers have discovered 26 new likely black holes in the neighboring Andromeda galaxy — the largest haul of black hole candidates ever found in a galaxy apart from our own. The central region of the Andromeda galaxy is chock-full of black holes, according to extensive observations with NASA’s Chandra X-ray Observatory. 26 new stellar-mass black hole candidates have been identified, adding to nine previously known and bringing the grand total to 35. Scientists believe it may be 'tip of the iceberg'"

Once one company has done it all others should stop.

Well, not necessarily. There could be lot of interesting (read creative) ideas one could have missed. And indirectly, it creates a healthy compitition everybody benefits from.

If that was not the case, we would have had only one type of car, only one type of plane, only one type of phone..and the list may go on.

I agree that dogs do great job. However trained dogs are expensive and they have a time limit.

Back on topic, I was involved in design electronics and algorithms of chemical detector useful for military/security forces. Right now I am involved in design of device that would detect certain diseases. We used nanomaterial and I believe it does great job. It provides great sensitivity and helps package everything in a small 3 inch box.

IANAC, could anybody explain me whether the technology used in the device "ion mobility spectrometry" is better?

+ - X-Ray Laser for creating supercharged particles->

Submitted by William Robinson
William Robinson (875390) writes "Scientists have found way to use X-Ray Laser for creating supercharged particles. The specific tuning of the laser's properties can cause atoms and molecules to resonate. The resonance excites the atoms and causes them to shake off electrons at a rate that otherwise would require higher energies. This could be used to create highly charged plasma."

William Robinson (875390) writes "There are iteresting stories about which tech companies are supporting Obama and which tech companies are supporting Romney. According the article, Obama's biggest donators features the likes of Microsoft, Google, IBM and Comcast whereas the only tech name on Romney's list is EMC. The tech community are choosing Obama because they see him as man with a similar vision"
