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…
It's no secret to New Yorkers that Mayor de Blasio has a "strained" relationship with the NYPD and its Commissioner, William Bratton. Mayor de Blasio and Commissioner Bratton have publicly butted heads over a whole host of issues from Black Lives Matter, to the size of the police force, to the effectiveness of the City Council. Early last year the NYPD famously turned their backs on Mayor de Blasio as he delivered the eulogy for a fallen police officer.
Therefore, it shouldn't be that shocking that Commissioner Bratton surprised Mayor de Blasio yesterday with an article in the ...
Watching Jon Snow’s epic “Battle of the Bastards” scene in the penultimate episode of this season’s Game of Thrones gives investors a sense of how it has felt to manage money during some periods over the past year. Surging enemies forming a seemingly impossible perimeter, a crush of fellow soldiers on the field, arrows coming in overhead, and the need to avoi...
US equity indexes traded in a narrow range today and finished mixed ahead of Fed Wednesday. Our benchmark S&P 500 exhibited a bit of volatility in the first 90 minutes, hitting its intraday high and low about an hour apart. The index then struggled with yesterday's closing price during the lunch hour and again at the close. It managed to eke out a 0.03% gain as we move toward tomorrow's FOMC minutes and rate decision, expect by most analysts to remain unchanged.
The yield on the 10-year closed at 1.57%, down one basis point from the previous session.
Here is a snapshot of past five sessions in the S&P 500.
Here is a daily chart of the index. We've highlighted the unusually narrow pattern over the past nine sessions, b...
The U.S. Federal Reserve is expected to keep interest rates unchanged this week, deferring any possible increase until September or December, as policymakers hold out for more evidence of a pickup in inflation.

Companies around the world are exploring blockchain, the technology underpinning digital currency bitcoin. In this Blockchain unleashed series, we investigate the many possible use cases for the blockchain, from the novel to the transformative.
Most people agree we do not need to know how a television works to enjoy using one. This is true of many existing and emerging technologies. Most of us happily drive cars, use mobile phones and send emails without knowing how they work. With this in mind, here is a tech-free user guide to the blockchain - the technology infrastructure behind bitcoin...
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.

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.
