Rather than discounting the spread of an intelligent civilization, the Fermi Paradox merely points out that advanced civilizations with exponential growth are unlikely to exist, due to finite resources, suggest Pennsylvania State University scientists.

An experimental drug that has proven effective in treating muscular dystrophy also works for cystic fibrosis, according to researchers at the University of Alabama at Birmingham.
The compound PTC124 helps to “rescue” faulty proteins that lead to illnesses. The drug holds promise in treating more than 2,400 genetic diseases caused by a certain class of DNA mutation.
In the UAB tests performed on mice, PTC124 restored to normal… read more

Researchers might never fully describe some bacteria and viruses–because their genomes are infinite, according to scientists at The Institute for Genomic Research (TIGR), writing in the September 19-23 early online edition of the Proceedings of the National Academy of Sciences (PNAS).
With collaborators at Chiron Corporation, Harvard Medical School and Seattle Children’s Hospital, they compared the genomic sequence of eight isolates of the same bacterial species, Streptococcus agalactiae, and… read more

Scientists at Tsinghua University in Beijing have calculated from first principles what a sheet of graphene might be like.
It’s currently only possible to make graphene in tiny scraps. So they suggest ways to stack these sheets and bond them together to make something larger.
Their model predicts the links between graphene layers will increase the distance between them, thereby reducing the density to about half that of… read more

MIT’s Rodney A. Brooks is among researchers leading the charge to develop a smarter and more useful artificial creature.
“What we need is low-cost dexterous manipulation,” Brooks says. “Right now we don’t even have high- cost dexterous manipulation.”
An electrochemical process for coating metal implants to make them resemble biological material vastly improves their functionality, longevity and integration into the body a Tel Aviv University researcher has found.

A cargo ship has completed a two week journey using a computer-controlled kite to help tow the ship, saving engine power and fuel.
SkySails, the maker, estimates fuel savings of 10 to 15% during the time the kite was flying, representing a savings of about $1,000 to $1,500 in fuel costs per day. SkySails claims that freight ships and cruise liners could reduce fuel consumption by up to 50%… read more

Physicists in Australia have slowed a speeding laser pulse and captured it in a crystal, a feat that could be instrumental in creating quantum computers.
The scientists slowed the laser light pulse from 300,000 kilometers per second to just several hundred meters per second, allowing them to capture the pulse for about a second.

The top 10% of smart-phone users — the smartphoniacs — are the true addicts of the information age.
You might be a smartphoniac if you:
- Take your smartphone to the restroom
- Send messages while driving
- Sneak a look at your messages during a conversation
- Suffer from sprained or elongated thumbs
- Openly use your smart phone in inappropriate places, such as first dates

A team of scientists from Iowa, Taiwan, and Germany demonstrates for the first time that embryonic stem cells can be used to create functional immune system blood cells.
This is an important step in the use of embryonic stem cells as an alternative source of cells for bone marrow transplantation.

California Institute of Technology researchers have developed a method of “demultiplexing” the signals from ultrahigh-density nanowire circuits — electrically addressing large numbers of individual nanowires using many fewer electrical connectors.
The technique will help in analyzing the complex signals that such sensors generate when they are testing complex biological samples.
Dr. Heath, who is a principle investigator of one of the NCI’s Centers of Cancer Nanotechnology Excellence, and… read more
