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…
With California finally mattering in an election season, it might be the final state primary before the Democratic race for president is set in stone. Regardless, recent developments have made one thing astoundingly clear: Donald Trump will almost surely defeat Hillary Clinton in a head to head matchup - and that’s why a vote...
In a stark warning as to what will happen if Chancellor Angela Merkel allows Turkish citizens visa-free travel throughout Europe, Turkish President Recep Tayyip Erdogan says “Contraception is Treason, Women Not Equal to Men, Muslims Must Multiply Descendants “.
St. Louis Federal Reserve President James Bullard said on Monday global markets appear to be "well-prepared" for a summer interest rate hike from the Fed, although he did not specify a date for the policy move.
Semiconductors were the star of the week. The index cleared Match/April congestion and posted six consecutive winning days in a row. Technicals are all in the green and the index is above all key moving averages. Weakness will be a buying opportunity; a test of the 50-day MA would be a good start.
The Russell 2000 managed to regain the prior rising channel. Technicals are positive although it still has to make up relative ground against the Nasdaq. The index hasn't yet cracked new highs but one more days gain may be en...
The rally in mining stocks since the first of the year has been very impressive.

Do you remember when you were growing up and all your friends were allowed Atari game consoles but you weren’t?
Well, I do and the things seemed as foreign to me as Venus. Mostly because the little time I managed to spend on the gaming consoles when my friends weren’t hogging them I found it all a bit silly. I never “got” computer games, and to this day still have poor comprehension of things like Angry Birds.
I suspect that many people around the world view Bitcoin in the same way as I view Angry Birds: with mild amusement and a general lack of understanding as to what the hell all the fuss is about.
I was thinking of this since a buddy of mine recently started ...
After a three-year bull run that more than quadrupled its value by its peak last July, IBD’s Medical-Biomed/Biotech Industry Group plunged 50% by early February, hurt by backlashes against high drug prices and mergers that seek to lower corporate taxes.
Although we try to stay focused on finding and managing promising trade ideas, the comments in the comment section sometimes take a political turn (for access, try PSW — click here!). So today, Jean Luc writes,
The GOP debate last night was just unreal – are these people running to be president of the US or to lead a college fraternity! Comparing tool size? The only guy that looks semi-sane is Kasich. The other guys are just like 3 jackals right now.
And something else – if Trump is the candidate, that little Romney speech yesterday is probably already being made into a commercial. And all these little snippets from the debate will also make some nice ads! If you are a conservative, you have to be scared now.

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.
