...change as the car speeds by. The Navy's TRANSIT navigation system was developed in the 1960s, relying on six satellites and designed originally for use by submarines. More than 10 satellites were eventually launched, though ground units had to wait up to several hours to pick up a signal. Meanwhile, engineers Ivan Getting and Bradford Parkinson began leading a Defense Department project to provide continuous navigation information, leading to the development of GPS (formally known as NAVSTAR GPS) in 1973. The military launched the first GPS satellite in 1978 and completed the system in 1995. GPS uses a "constellation...
...that is, you're connected to the Net. AT&T recently announced a pilot project in Atlanta and Philadelphia that lets netbook users log on anywhere they can get a 3G cellular signal, which will greatly expand coverage beyond the usual islands of wi-fi. In exchange for commitment to a two-year data-service plan, AT&T is subsidizing a range of mini-laptops, which start as low as $49.99. The data plan costs from $40 per month (for 200 MB, which is good for business users), to $60 per month (for 5 GB, enough to move around music...
...financials may have a couple more months of relative strength as portfolios readjust, but when might banks and brokers reemerge as stock-market leaders? Before financials can emerge in a leadership position we will need to see some semblance of very stern regulation in the financial field, which will signal to investors that financial companies are clean - at that point they may even be overregulated. Also, between 2001 and 2007 financials added a bunch of capacity, and that needs to recede, through consolidation or simply going out of business. That's still a few years...
...related genetic region on chromosome 17 that contained genetic variants more common in boys than in girls. While nearly 40% of the general population has the most common form of CACNA1G, one variant of the gene was more prevalent in autistic boys, researchers found. "There is a strong genetic signal in this region," says Dr. Daniel Geschwind, director of UCLA's Center for Autism Research and Treatment and one of the study's co-authors. "But this gene doesn't explain all of that signal or even half of it. What that means is that there are many more genes...
...find a benefit in reciprocating. Releasing the detained Iranians could build trust for talks between Washington and Tehran on security issues in Afghanistan and Iraq and also on the thorny issue of Iran's nuclear program. And it could strengthen the hand of the Iranian pragmatists who sent the signal through the European diplomatic channel...
