Hugh Pickens writes writes"PC Magazine reports that the Commerce Department has unveiled a national broadband inventory map, which will allow the public to see where high-speed Internet is available throughout the country. Users can search by address, view data on a map, or use other interactive tools to compare broadband across various geographies, such as states, counties or congressional districts. Commerce officials say the information can help businesses decide if they want to move to a certain location, based on broadband availability. The map, costing about $200 million, and financed through the 2009 Recovery Act shows that 5-10 percent of Americans lack broadband access at speeds that support a basic set of applications. Another 36 percent lack access to wireless service. Community anchor institutions like schools and libraries are also 'largely underserved,' the data finds and two-thirds of surveyed schools subscribe to speeds lower than 25 Mbps and only 4 percent of libraries subsribe to speeds greater than 25 Mbps. 'The National Broadband Map shows there are still too many people and community institutions lacking the level of broadband service needed to fully participate in the Internet economy,' says Larry Strickling, assistant secretary of the National Telecommunications and Information Administration (NTIA). 'We are pleased to see the increase in broadband adoption last year, particularly in light of the difficult economic environment, but a digital divide remains.'"

An anonymous reader writes" According to the CBC: 'An unprecedented cyberattack on the Canadian government from China has given foreign hackers access to highly classified federal information, and forced at least two key departments off the internet, CBC News has learned. The attack, first detected in early January, left Canadian counter-espionage agents scrambling to determine how much sensitive government information may have been stolen and by whom.' It should be noted that the Auditor-General warned of this months ago and was ignored by everyone as she usually is. It should also be noted that public sentiment towards China is getting very, very testy."

Children of Working Moms Face More Health Problems, Study Suggests

Most Stroke Patients Not Getting Clot-Busting Treatment in Timely Manner

ScienceDaily (Feb. 10, 2011) — Less than one-third of acute stroke patients treated with intravenous tissue plasminogen activator (tPA) receive the clot-busting drug within 60 minutes of their hospital arrival, according to research presented at the American Stroke Association's International Stroke Conference 2011. The research is simultaneously published in Circulation: Journal of the American Heart Association.

Offspring of Female Rats Given Folic Acid Supplements Develop More Breast Cancer, Study Suggests

Trial and Error: The Brain Learns from Mistakes

ScienceDaily (Feb. 14, 2011) — In the developing brain, countless nerve connections are made which turn out to be inappropriate and as a result must eventually be removed. The process of establishing a neuronal network does not always prove precise or error free. Dr. Peter Scheiffele's research group at the Biozentrum of the University of Basel have been able to document this phenomenon using advanced microscopy techniques in the developing cerebellum, a brain area required for fine movement control. Dr. Scheiffele's group has discovered that a protein traditionally associated with bone development is responsible for correcting errors while neurons connect to their correct partners in the cerebellum.
