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…
I recently pointed out that the Fed’s 5-year campaign to drive the 30-year mortgage rate from 6.5% to 3.3% had accomplished nothing except to touch off another of those pointless “refi” booms which enable homeowners to swap an existing mortgage for a new one carrying a significantly lower interest rate and monthly service cost. Such debt churning exercises have been sponsored repeatedly by the Fed since the S&L debacle of the late 1980s.

The set-up coming into this past week was clean: SPX and NDX exhibited breadth extremes from which they usually bounce and April Opex is a seasonally strong week (post).
In the event, SPX rose nearly 3%. In the process it exhibited a familiar pattern: overnight gaps in the past 4 days accounted 60% of the week's gain. Cash hours, when liquidity is greatest, was not where the meat of the gains took place. That was even more true for RUT and NDX which only posted cash hour gains during two of the four days.
After a sharp drop and a strong bounce, where does that leave the markets? Let's run through each of our market indicators...
Nike (NYSE: NKE) is laying off 70-80 percent the engineers who created its FuelBand Fitness Tracker. according to a post that first surfaced on the social network Secret and was reported Saturday by CNET. Approximately 55 of the 70 employees on Nike's Digital Sport hardware team are reportedly being cut.
In "Insatiable" the Economist says "The cost of stopping the Russian bear now is high—but it will only get higher if the West does nothing".
Economist: Mr Putin has used the Ukrainian crisis to establish some dangerous precedents. He has claimed a duty to intervene to protect Russian-speakers wherever they are. He has staged a referendum and annexation, in defiance of Ukrainian law. And he has abrogated a commitment to respect Ukraine’s borders, which Russia signed in 1994 when Ukraine gave up nuclear weapons. Throughout, Mr Putin has shown that truth and the law are whatever happens to suit him at the time.

This one matters a lot. Abenomics was predicated on a lunatic notion—namely, that the economic ills from Japan’s massive debt overhang could be cured by a central bank bond buying spree that was designed to be nearly 3X larger relative to its GDP than that of the Fed. Yet anyone with a modicum of common sense and market...
Shares in Chipotle Mexican Grill Inc. (Ticker: CMG) opened higher on Thursday morning, rising more than 6.0% to $589.00, after the restaurant operator reported better than expected first-quarter sales ahead of the opening bell. But, the stock began to falter just before lunchtime on concerns the burrito-maker will increase menu prices for the first time in three years. The price of Chipotle’s shares have since fallen into negative territory and currently trade down 3.5% on the session at $532.89 as of 1:50 p.m. ET.
Last week’s market performance was nasty again, especially for the Small-cap Growth style/cap, down 4%. Large-caps faired the best, losing only 2.7%. That’s ugly and today’s market seemed likely to be uglier today with escalating tensions over the weekend in Ukraine.
But once again, positive economic trumped the beating of the war drums. Retail Sales jumped up 1.1% over a projected 0.8% and last month’s tepid 0.3%, which was revised up to 0.7%. While autos led, sales were up solidly overall. Business inventories were about as expected with a positive tone. Citigroup (C) handily beat estimates to add to the morning’s surprises. As a result, the market was positive through most of the day, led by the DJI, up 0.91%, and the S&P 500, up 0.82%. NASDAQ had a less...
[Facebook] The social network is only weeks away from obtaining regulatory approval in Ireland for a service that would allow its users to store money on Facebook and use it to pay and exchange money with others, according to several people involved in the process.
The authorisation from Ireland’s central bank to become an “e-money” institution would allow ...

If GOOGLE, the NSA, and Steve Jobs all got together in a room with the task of building a tremendously accurate trading algorithm… it wouldn’t just be any ordinary system… it’d be the greatest trading algorithm in the world.
Well, I hate to break it to you though… they never got around to building it, but my friends at Market Tamer did.

And so the circus begins in Union Square, San Francisco for this weeks JP Morgan Healthcare Conference. Will the momentum from 2013, which carried the S&P Spider Biotech ETF to all time highs, carry on in 2014? The Biotech ETF beat the S&P by better than 3 points.
As I noted in my previous post, Biotechs Galore - IPOs and More, biotechs were rushing to IPOs so that venture capitalists could unwind their holdings (funds are usually 5-7 years), as well as take advantage of the opportune moment...
