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…
Wow, did the dollar move down this week! It dropped more than it has in quite a while. It fell 1.3mg gold, or 0.1g silver.
Gold and silver bugs of course are excited, as they look at it as the prices of the metals going up $55 and 72 cents respectively. The collapse of what most think of as money—including especially said gold and silver bugs—is great fun and profitable. At least if you’re short the dollar.
By the way, when we say the dollar fell we do not mean in terms of its derivatives such as euro, pound, yuan, and so on. We’re well aware that the dollar index fell from 99.6 to 97. The euro and other currencies are no more suitable for measuring the dollar, than, well the dollar is to me...
A quick post before the Superbowl begins. Friday's action was very disappointing if you were in the bullish camp; poor jobs data contributing to the malaise. However, investors can view this as another buying opportunity, with the Nasdaq clocking the 10% percentile of historic weak prices dating back to 1971, and the Russell 2000 making fast work of a push back to 958. Again, it's not about investing everything at once, but perhaps using the coming year(?) to build long term positions. I would be happier to see a 40-60% trim from highs - keep an eye on my bottom watch table, but this is the kind of action which helps reset the bulls count.
The S&P registered a clear break of rising trend. Volume was lighter, so it wasn't necessarily a panic sell. And while it could be viewed as a breakown, the glass half full crew would see this as a drop back...
Last week, I discussed the boost the market received as the BOJ made an unexpected move into negative interest rate territory combined with end of the month buying by portfolio managers. I wrote:
“However, the announcement by the Bank of Japan (BOJ) to implement negative interest rates in a desperate last attempt to boost economic growth in Japan was only the catalyst that ignited the bulls. The “fuel” for the buying came from the end of the month portfolio buying by fund managers.”
But more importantly, was the push higher by stocks that I have been discussing with you over the last couple of weeks. ...
Throughout the past 30 days of wild volatility, here’s what I didn’t do.
Panic. Worry. Sell.
In fact, the best I did was add to a couple of positions yesterday. The world was already in an uncertain state for the past 3+ years. It’s just that with the market rising, we pushed the issue to the back of our mind and ignored it.

A number of systemic, structural forces are intersecting in 2016. One is the rise of non-state, non-central-bank-issued crypto-currencies.
We all know money is created and distributed by governments and central banks. The reason is simple: control the money and you control everything.
The invention of the blockchain and crypto-currencies such as Bitcoin have opened the door to non-state, non-central-bank currencies--money that is global and independent of any state or central bank, or indeed, any bank, as crypto-currencies are structurally peer-to-peer, meaning they don't require a bank to function: people can exchange crypto-currencies to pay for goods and services without a bank acting as a clearinghouse for all these transactions.
Last year, the S&P 500 large caps closed 2015 essentially flat on a total return basis, while the NASDAQ 100 showed a little better performance at +8.3% and the Russell 2000 small caps fell -5.9%. Overall, stocks disappointed even in the face of modest expectations, especially the small caps as market leadership was mostly limited to a handful of large and mega-cap darlings.
Notably, the full year chart for the S&P 500 looks very much like 2011. It got off to a good start, drifted sideways for...

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.
