Omega-3 lesson: Not so much brain boost as fishy research

This is a good article highlighting how scientific research gets misrepresented in the media, making it important to go to the original source.  Moreover, often an experiment measures one thing (a surrogate) but makes conclusions that go well beyond what was actually measured. (E.g. high cholesterol levels being used as a surrogate for heart attack risk.) – Ilene 

Omega-3 lesson: Not so much brain boost as fishy research

By Ben Goldacreguardian.co.uk

Fish oil helps schoolchildren to concentrate ran a headline in the Observer. Regular readers will remember the omega-3 fish oil pill issue. The entire British news media has been claiming for several years now that there are trials showing that the pill improves school performance and behaviour in mainstream children, despite the fact that no such trial has ever been published.

There is something very attractive about the idea that solutions to complex problems in education lie in a pill.

[...]

This paper showed no difference in performance at all. Since it was a brain imaging study, not a trial, the results of the children’s actual performance in the attention task was only reported in a single paragraph. But these results were clear: "There were no significant group differences in percentage correct, commission errors, discriminability, or reaction time."

So this is all looking pretty wrong. Are we even talking about the same academic paper? I’ve a long-standing campaign to get mainstream media to link to original academic papers when they write about them, at least online, with some limited success on the BBC website. I asked the writer Campbell which academic paper he was referring to, but he declined to answer, and passed me on the Stephen Pritchard, the readers’ editor for the Observer, who answered a couple of days later to say he did not understand why he was being involved. Eventually Campbell confirmed, but through Pritchard, that it was indeed a paper from the April edition of the American Journal of Clinical Nutrition.

[...]

Similarly, drug reps and researchers will often announce that their intervention has some kind of effect on some kind of elaborate measure of some kind of surrogate outcome: maybe a molecule in the blood goes up in concentration, or down, in a way that suggests the intervention might be effective.

This is all very well. But it’s not the same as showing that something really does actually work back here in

WTI Dips After Big Surprise Build In Gasoline Inventory

Courtesy of ZeroHedge View original post here.

Amid all the chaos in equity markets, oil managed to bounce back to modest gains on the day with WTI as a weaker dollar offset some concerns of a growing pile up of crude in the U.S. Gulf Coast as refineries there cut runs in response to the Colonial Pipeline shutdown.

Traders are expecting “a gradual resolution to the Colonial Pipeline shutdown,” according to Louise Dickson, an analyst at consultant Rystad Energy.

“The market is again looking to Asia, Covid-19 cases, and the next signals for oil demand outlook.&r...

Will Historic Selloff In Treasury Bonds Turn Into Opportunity?

Courtesy of Chris Kimble

Long-dated treasury bonds have been crushed over the past year, sending ETFs like TLT (20+ Year US Treasury Bond ETF) spiraling over 20%.

Improving economy? Inflation concerns? Perhaps a combination of both… interest rates have risen sharply and thus bond prices have fallen in historic fashion.

Today’s chart looks at $TLT over the past 20 years. As you can see, the recent decline has truly been historic. $TLT’s price has swung from historically overbought highs to oversold lows.

At present, the long-dated bond ETF ($TLT) is trading 7.8% below its 200-...

Adaptive Fibonacci Price Modeling System Suggests Market Peak May Be Near

Courtesy of Technical Traders

Our Adaptive Fibonacci Price Modeling system is suggesting a moderate price peak may be already setting up in the NASDAQ while the Dow Jones, S&P500, and Transportation Index continue to rally beyond the projected Fibonacci Price Expansion Levels.  This indicates that capital may be shifting away from the already lofty Technology sector and into Basic Materials, Financials, Energy, Consumer Staples, Utilities, as well as other sectors.

This type of a structural market shift indicates a move away from speculation and towards Blue Chip returns. It suggests traders and investors are expecting the US consumer to come back strong (or at least hold up the market at...

Texas, Florida, Arizona, Georgia – The Branch COVIDIANS Are Still Burning Down the House

The numbers of new cases in some of the hardest hit COVID19 states have started to plateau, or even decline, over the past few days. A few pundits have noted it and concluded that it was a hopeful sign. 

Is it real or is something else going on? Like a restriction in the numbers of tests, or simply the inability to test enough, or are some people simply giving up on getting tested? Because as we all know from our dear leader, the less testing, the less...
