Ebola scams are sickening
We’ve seen it before. A medical crisis emerges and the scam artists crawl out of the woodwork. Fearful citizens pop open their wallets and fork out hard-earned money for nonsensical “cures.” When it comes to a disease for which science cannot offer an effective treatment, quacks quickly rush in to fill the vacuum.

Green coffee beans give science a black eye
Dr. Oz didn’t mince his words when he described the wondrous effects of green coffee been extract. “Magical,” “staggering,” an “unprecedented discovery!” “Finally, a cure for obesity” he breathlessly gushed. I gasped too. Not at the results of the study that sent Oz into rapture, but at the credulity of the man. Read More.
Cherry Picking Cranberry Juice Data
Cranberry juice manufacturers are adept at cherry-picking data. Of course this is not a unique pursuit. Be it milk, or blueberries or pomegranates or artificial sweeteners or beef or turmeric or bottled water or virtually any other food or beverage that is on the market, its producers scour the scientific literature for any study that can be used as promotional material.

We need rational discussion about pesticides, without rhetoric
David Copperfield performed many an illusion on his television specials with his hair blowing in the wind, tussled by an offstage fan. I was reminded of that effect by an episode of the Dr. Oz show in which the hot air so often generated by the host was amplified by a fan à la Copperfield. Read More.
Did You Know?
This may come as a shock to some people but lead pencils do not contain any lead. Never did. The “lead” actually is a mixture of graphite and clay; the more graphite, the softer and darker the point. The mistake in terminology can be traced back to the ancient Romans who actually used pieces of lead to draw lines on papyrus scrolls in order to guide them in writing with a tiny brush called a pencillus. Lead is a very soft metal and pieces readily rub off. The Romans never realized that lead was potentially toxic but today we know that even tiny amounts ingested can result in poisoning. So it is a good thing we do not have “lead” pencils for children to chew on.

Smell Turns Up in Unexpected Places
Smell is one of the oldest human faculties, yet it was one of the last to be understood by scientists. It was not until the early 1990s that biologists first described the inner workings of olfactory receptors — the chemical sensors in our noses — in a discovery that won a Nobel Prize. Read More.

The enigma of methane on mars
Methane, an indicator of life? Methane (CH4) is an organic molecule present in gaseous form in the Earth's atmosphere. More than 90% of methane on our home planet is produced by living organisms. The recent detection of plumes of methane in the northern hemisphere of Mars is of great interest because of its potential biological origin, though other explanations may also be possible. Read More.
