Greenough showed the effects of enriched and deprived environments on cortical connectivity and thickness in a series of studies. This is one of his early studies:

Science. 1972 Jun 30;176(4042):1445-7. Rearing complexity affects branching of dendrites in the visual cortex of the rat. Volkmar FR, Greenough WT.

"Higher-order dendritic branching is considerably greater in Golgistained neurons from the occipital cortex of rats reared in groups in a complex environment than in similar neurons of littermates reared individually in laboratory cages have intermediate amounts of branching, while lower-order branching did not appear to be affected by any rearing environment."

+ - Why Not Replace SSL Certificates With PGP Keys? 9

vik (17857) writes "The whole SSL process has been infiltrated by the NSA, GCSB and other n'er-do-wells. If governments want a man-in-the-middle certificate they simply issue a secret gagging order to the CA to make them issue one. Consequently "certified" SSL certificates can no longer be trusted. Ironically self-issued certificates are more secure, but not easily verified.

However, PGP/GPG keys can be trusted and independently verified. They are as secure as we can get for now. Why not replace the broken SSL CA system with GPG/PGP encryption keys? Make the NSA-infiltrated stuff obsolete, and rely on a real-world web of trust?"

In an article published in PLOS One "Seeing Is Believing: Neural Representations of Visual Stimuli in Human Auditory Cortex Correlate with Illusory Auditory Perceptions" the authors showed that visual stimuli can influence neural signals in the auditory processing part of the brain and change what a person hears. In this study patients were shown videos of an auditory illusion called the McGurk Effect while electrical recordings where made from the surface of the cerebral cortex."

Lobby your local city and county officials to support the installation of fiber infrastructure. Along the Wasatch Front we have the excellent UTOPIA project, which brings fiber to the home. Local cities used bonds to support setting up the infrastructure, and home owners pay for the connection from the street to their house. The fiber infrastructure is treated like a utility and any ISP can compete for your business. I have a symmetric 100 MB connection for about about 1/3 less than Comcast was charging me for a 15 MB connection, and I get MUCH better service.

According to the US Bureau of Labor Statistics, Biomedical Engineering is one of the fastest growing occupations and has a median income of over $80,000. I think that this NIH study, which was run mainly by people in academia, doesn't fully account for the jobs in industry.

Most researchers will think about this for about 2 seconds and then publish in the journal with the most prestige and highest impact factor that they can. Publishing in high impact journals is a major factor in promotion and tenure for professors, so until universities adapt their policies on promotion and tenure, professors will continue to published in prestigious and expensive closed access journals. When reviewing someone for promotion or tenure, high-level administrators don't have time to read all the journal articles a professor has published, so they really heavily on g-indices and/or h-indices that are based upon journal impact factor scores.

Comment: No dexterity in the fingers (Score 4, Informative) 56

Pretty amazing surgery, but watching the videos shows limited restoration of function. The key is getting the transplanted/regenerating nerves to make the proper connections. The surgery is not going to re-wire the incredible number of connections made during development. Neural prostheses currently offer better dexterity and restoration of function than the nerve transplant. However, it is likely only a matter of time (maybe sever decades) before the neural re-wiring problem is solved.

"Dell and Baidu, the Chinese search giant with over 80% marketshare in its home-country, unveiled the Streak Pro on Tuesday (via Computerworld). The device has a 4.3 AMOLED screen with 960×540 resolution and packs a 1.5 GHz dualcore Qualcomm processor. Most notably, however, is the operating system it runs: a forked Android version dubbed Baidu Yi, which replaces Google’s services with those of Baidu."

How will this impact Google's support for Android and open source in general?"

Hugh Pickens writes writes "Nextgove reports that Michael Hayden, former director of both the NSA and the CIA, says the United States may seriously want to consider creating a new Internet infrastructure to reduce the threat of cyberattacks and several current federal officials, including U.S. Cyber Command chief Gen. Keith Alexander, also have floated the concept of a ".secure" network for critical services such as financial institutions, sensitive infrastructure, government contractors, and the government itself that would be walled off from the public web. Unlike .com, .xxx and other new domains now proliferating the Internet, .secure would require visitors to use certified credentials for entry and would do away with users' Fourth Amendment rights to privacy. "I think what Keith is trying to suggest is that we need a more hardened enterprise structure for some activities and we need to go build it," says Hayden. "All those people who want to violate their privacy on Facebook — let them continue to play." Clay Dillow writes that on the existing internet everyone does everything online anonymously, and while that’s great for liberties, it’s also dangerous when cyber criminals/foreign hackers are roaming the cyber countryside. Under the proposed .secure internet "you may not be able to go to certain neighborhoods of the Web without showing your papers at a checkpoint--and perhaps subjecting yourself to one of those humiliating electronic pat-downs as well," writes Dillow. "Those who want to remain anonymous on the Web can still frolic about in the world of dot-com, but in the dot-secure realm you would have to prove you are you.""
