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…
Five trading days in the Dow Jones Industrial Average and a roundtrip between here and the close last Friday.
God forbid you had gone a few days doing something other than obsessing over the market. You’d take a look at the current level and conclude that not much has gone on.
The hard part is that we don’t always get a V-shaped bounce. And sometimes, the bounce isn’t permanent – just a temporary development to suck more buyers in. But you can’t know in advance, nor can anyone else, so its probably not a great idea ...
China is in severe trouble and that trouble has already been reverberating around EM exporters for a number of years. It is just one of many dollar currency peg countries that have experienced tightening conditions because of higher US interest rate guidance and dollar strength. An unwelcome addition to their own domestic issues, but always a circular outcome, as they are inextricably linked to the US by their Bretton Woods II relationship. By devaluing and thus de-stabilising the 'nominal' anchor for Asian exchange rates, they will crush th...
A second day of gains keeps pressure on shorts in squeezing them out of their positions, but is also looking to sucker shorts into trying to second guess when this rally will end.
The S&P is heading fast towards 2,044. Given the speed at which it has enjoyed this advance it will be there by Tuesday! In reality, it will likely slow before it gets there. When markets do head lower it will be important they do so slowly to sow further doubt into shorts.
The Nasdaq will be testing resistance tomorrow, and is close to coming up against its 200-day MA. Those who bought the low will be very happy.
China’s government intervened in the stock market on Thursday to end a $5 trillion rout, according to people familiar with the matter.
China wants to stabilize equities before a Sept. 3 military parade celebrating the 70th anniversary of the victory over Japan during World War II, said the people, who asked not to be identified because the move wasn’t publicly announced. The intervention is the latest measure to ensure nothing detracts from the parade, an event the government will use to demonstrate its rising military and political might.
If one takes the highs of 1987 and the lows of 2003 and ties them together and then projects a line into the future, you get line (1). The Dow hit line (1) and its Fibonacci 161% level in May and the Dow could make no more upward progress after that!
Speaking of momentum, it reached lofty levels at the same time! Momentum recently hit levels last seen in 2000 and 2007.
Garnero Group Acquisition Company (NASDAQ: GGAC), a public investment vehicle formed for the purpose of effecting a merger, acquisition or similar business combination, and Grupo Colombo ("Grupo Colombo" or "GC"), a leading apparel retailer in Brazil, announced today that they have entered into a definitive investment agreement to merge the companies in a transaction valued at approximately $330 million. The combined company will remain listed on the NASDAQ Stock Market and be renamed "Garnero Colombo Inc."

The dark veil around China is creating a little too much uncertainty for investors, with the usual fear mongers piling on and sending the vast buy-the-dip crowd running for the sidelines until the smoke clears. Furthermore, Sabrient’s fundamentals-based SectorCast rankings have been flashing near-term defensive signals. The end result is a long overdue capitulation event that has left no market segment unscathed in its mass carnage. The historically long technical consolidation finally came to the point of having to break one way or the other, and it decided to break hard to the downside, actually testing the lows from last ...

With the VIX index jumping 120 percent on a weekly basis, the most in its history, and with the index measuring volatility or "fear" up near 47 percent on the day, one might think professional investors might be concerned. While the sell off did surprise some, certain hedge fund managers have started to dip their toes in the water to buy stocks they have on their accumulation list, while other algorithmic strategies are actually prospering in this volatile but generally consistently trending market.
Stock market sell off surprises some while others were prepared and are hedged prospering
Naysyers are warning that the recent plunge in Bitcoin prices - from almost $318 at its peak during the Greek crisis, to $221 yesterday - is due to growing power struggle over the future of the cryptocurrency that is dividing its lead developers. On Saturday, a rival version of the current software was released by two bitcoin big guns. As Reuters reports, Bitcoin XT would increase the block size to 8 megabytes enabling more transactions to be processed every second. Those who oppose Bitcoin XT say the bigger block size jeopardizes the vision of a decentralized payments system that bitcoin is built on with some believing ...

Baxter Int. (BAX) is splitting off its BioSciences division into a new company called Baxalta. Shares of Baxalta will be given as a tax-free dividend, in the ratio of one to one, to BAX holders on record on June 17, 2015. That means, if you want to receive the Baxalta dividend, you need to buy the stock this week (on or before June 12).
Back in December, I wrote a post on my blog where I compared the performances of various ETFs related to the oil industry. I was looking for the best possible proxy to match the moves of oil prices if you didn't want to play with futures. At the time, I concluded that for medium term trades, USO and the leveraged ETFs UCO and SCO were the most promising. Longer term, broader ETFs like OIH and XLE might make better investment if oil prices do recover to more profitable prices since ETF linked to futures like USO, UCO and SCO do suffer from decay. It also seemed that DIG and DUG could be promising if OIH could recover as it should with the price of oil, but that they don't make a good proxy for the price of oil itself.

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.
