Do cell phones cause cancer? We’d all like to know, but unfortunately there’s no clear answer — yet. Now an intriguing new study takes a first step toward a possible answer, suggesting that holding your cell phone to your ear does have a measurable effect on the brain, even during cell-phone sessions of less than an hour.
Dr. Nora Volkow, director of the National Institute on Drug Abuse (part of the National Institutes of Health), reports Tuesday in the Journal of the American Medical Association (JAMA) that a cell phone’s electromagnetic field can cause changes in brain activity. Specifically, she and her team found that the regions nearest to the antenna of closely held mobile devices showed higher rates of energy (or glucose) consumption.
Before you start to panic that all your cell-phone confessionals have set you up for some kind of brain tumor, remember this: higher rates of glucose metabolism in the brain can mean a number of things. Yes, tumor cells may gobble up more glucose to fuel their relentless growth, but healthy brain cells need constant replenishment too, to keep up the intricate network of messages and connections that help us think, eat, move and stay alive. Depending on what you’re doing, different areas of your brain will require more glucose — if you’re playing Scrabble, your language centers might demand more attention, while deep emotions such as grief or euphoria will cause neurons involved in the mood-regulating limbic system to consume more energy.
Researchers found that the brain regions closest to the active phone’s antenna showed the highest rates of glucose activity, and Volkow says the next step is to understand what that means. “Is this a temporary change that recovers every single time, or do chronic, long periods of exposure potentially have long-lasting effects? We need to know that,” she says.
The study is the first to look at glucose metabolism as a marker for the effect of a magnetic
I write about major problems: the collapsing US economy, wars based on lies and deception, the police state based on “the war on terror” and other fabrications such as those orchestrated by corrupt police and prosecutors, who boost their performance reports by convicting the innocent, and so on. America is a very distressing place. The fact that so many Americans are taken in by the lies told by “their” government makes America all the more depressing.
Often, however, it is small annoyances that waste Americans’ time and drive up blood pressures. One of the worst things that ever happened to Americans was the breakup of the AT&T telephone monopoly. As Assistant Secretary of the US Treasury in 1981, if 150 per cent of my time and energy had not been required to cure stagflation in the face of opposition from Wall Street and Fed Chairman Paul Volcker, I might have been able to prevent the destruction of the best communications service in the world, and one that was very inexpensive to customers.
The assistant attorney general in charge of the “anti-trust case” against AT&T called me to ask if Treasury had an interest in how the case was resolved. I went to Treasury Secretary Don Regan and told him that although my conservative and libertarian friends thought that the breakup of At&T was a great idea, their opinion was based entirely in ideology and that the practical effect would not be good for widows and orphans who had a blue chip stock to see them through life or for communications customers as deregulated communications would give the multiple communications corporations different interests than those of the customers. Under the regulated regime, AT&T was allowed a reasonable rate of return on its investment, and to stay out of trouble with regulators AT&T provided excellent and inexpensive service.
Secretary Regan reminded me of my memo to him detailing that Treasury was going to have a hard time getting President Reagan’s economic program, directed at curing the stagflation that had wrecked President Carter’s presidency, out of the Reagan administration. The budget director, David Stockman, and his chief economist, Larry Kudlow, had lined up against it following the wishes of Wall Street, and the White House Chief of Staff James Baker and his deputy Richard Darman were representatives of VP…

The Socialists were routed in the second round of French elections this weekend. The centre-right UMP party led by Nicholas Sarkozy was the clear winner but Marone Le Pen's National Front had it best performance ever at the local level although it did not win any départements.
Friday's release of the publicly available data from the Economic Cycle Research Institute (ECRI) puts its Weekly Leading Index (WLI) at 131.6, up slightly from 131.2 the previous week. The WLI annualized growth indicator (WLIg) is at -3.2, up from the previous week's -3.6 and off its interim low of -4.9 in mid-January.
"The Song Remains the Same"
As I type this, the featured article on the ECRI website remains the February 23rd piece, "The Song Remains the Same" (full report requires a subscription), which illustrates the shrinking GDP growth during the seven business cycle expansions since 1970:

Well, it didn’t take long for the bulls to jump on their buying opportunity, with a little help from the bulls’ friend in the Fed. In fact, despite huge daily swings in the market averages driven by daily news regarding timing of interest rate hikes, the strength in the dollar, and oil prices, trading actually has been quite rational, honoring technical formations and support levels and dutifully selling overbought conditions and buying when oversold. Yes, the tried and true investing clichés continue to work -- “Don’t fight the Fed,” and “The trend is your friend.”
In this weekly update, I give my view of the cur...
While I'm not going to argue the point about the possibility that Bitcoin drops to $1, or less, (that could happen yet, but not for the reasons you propose) I felt it necessary to point out something you seem to have overlooked.

Bullish trades abound in Cypress Semiconductor options today, most notably a massive bull call spread initiated in the July expiry contracts. One strategist appears to have purchased 30,000 of the Jul 16.0 strike calls at a premium of $0.89 each and sold the same number of Jul 19.0 strike calls at a premium of $0.22 apiece. Net premium paid to put on the spread amounts to $0.67 per contract, thus establishing a breakeven share price of $16.67 on the trade. Cypress shares reached a 52-week high of $16.25 back on Friday, March 13th, and would need to rally 4.6% over the current level to exceed the breakeven point of $16.25. The spread generates maximum potential profits of $2.33 per contract in the event that CY shares surge more than 20% in the next four months to reach $19.00 by July expiration. Shar...

PSW Members - well, what a year for biotechs! The Biotech Index (IBB) is up a whopping 40%, beating the S&P hands down! The healthcare sector has had a number of high flying IPOs, and beat the Tech Sector in total nubmer of IPOs in the past 12 months. What could go wrong?
Phil has given his Secret Santa Inflation Hedges for 2015, and since I have been trying to keep my head above water between work, PSW, and baseball with my boys...it is time that something is put together for PSW on biotechs in 2015.
Cancer and fibrosis remain two of the hottest areas for VC backed biotechs to invest their monies. A number of companies have gone IPO which have drugs/technologies that fight cancer, includin...

Last fall there was some discussion on the PSW board regarding setting up a YouCaring donation page for a PSW member, Shadowfax. Since then, we have been looking into ways to help get him additional medical services and to pay down his medical debts. After following those leads, we are ready to move ahead with the YouCaring site. (Link is posted below.) Any help you can give will be greatly appreciated; not only to help aid in his medical bill debt, but to also show what a great community this group is.
