How Coffee Can Galvanize Your Workout
Can a cup of coffee motivate you to relish your trips to the gym this winter? That question is at the heart of a notable study of caffeine and exercise, one of several new experiments suggesting that, whatever your sport, caffeine may allow you to perform better and enjoy yourself more.

A short biography of Ron Paul
GREENVILLE, N.C. -- Long before he discovered Friedrich Hayek and other free-market economists, Ron Paul got a lesson in sound money from his oldest brother, Bill.
It was the height of World War II, and the Paul boys were laying aside quarters from their Pittsburgh Press routes and pooling pennies earned from pulling dirty milk bottles off the line at the family dairy to buy war bonds. One day, Ronnie suggested what was, in retrospect, a rather Keynesian solution: "Why doesn't the government just PRINT this money?"
"Well," Bill responded, "then the money wouldn't have any value."

Losing 'Virginity': Olive Oil's 'Scandalous' Fraud
Extra-virgin olive oil is a ubiquitous ingredient in Italian recipes, religious rituals and beauty products. But many of the bottles labeled "extra-virgin olive oil" on supermarket shelves have been adulterated and shouldn't be classified as extra-virgin, says New Yorker contributor Tom Mueller.
Mueller's new book, Extra Virginity: The Sublime and Scandalous World of Olive Oil, chronicles how resellers have added lower-priced, lower-grade oils and artificial coloring to extra-virgin olive oil, before passing the new adulterated substance along the supply chain. (One olive oil producer told Mueller that 50 percent of the olive oil sold in the United States is, in some ways, adulterated.)

MIT builds camera that can capture at the speed of light (video)
A team from the MIT media lab has created a camera with a "shutter speed" of one trillion
exposures per second -- enabling it to record light itself traveling from one point to another. Using a heavily modified Streak Tube (which is normally used to intensify photons into electron streams), the team could snap a single image of a laser as it passed through a soda bottle.

Vascular condition and MS share risk factors
People with a specific vascular condition, but no known neurological disease, display many of the same risk factors as people with multiple sclerosis, a new study shows.
Link
The study, published in PLoS One, is the first to investigate risk factors for chronic cerebrospinal venous insufficiency (CCSVI ) in which blood flow from the central nervous system to the periphery is impaired. It has been hypothesized that this narrowing of veins restricts blood flow from the brain, altering brain drainage and possibly contributing to brain tissue injury that is associated with MS.

Common risk factors
The study found that CCSVI risk factors occurred more frequently in 1) those with a history of mononucleosis, i.e. infected with Epstein-Barr virus; 2) those with irritable bowel syndrome; 3) those who smoke or have a history of smoking.
“All three are confirmed risk factors for MS,” says second author Bianca Weinstock-Guttman, professor of neurology. According to the results, individuals with CCSVI were 2.7 times more likely than individuals without CCSVI to have infectious mononucleosis, 3.9 times more likely to have irritable bowel syndrome and 1.98 times more likely to have a history of smoking.
“Our finding that a risk factor that is highly significant for MS—Epstein-Barr virus, indicated by a history of infectious mononucleosis—is strongly associated with CCSVI, is important,” says Zivadinov. “This is the first time a connection has been found between Epstein-Barr virus and CCSVI.

The Life Reports II
From David Brooks of the NY TIMES:
A few weeks ago, I asked people over 70 to send me “Life Reports” — essays about their own lives and what they’d done poorly and well. They make for fascinating and addictive reading, and I’ve tried to extract a few general life lessons: Link

Gifts That Say You Care
GIVE Grandma a bit of credit! These holidays, would she rather receive a silly reindeer sweater or help a schoolchild acquire glasses to see the blackboard clearly for the first time?
Choosing the perfect holiday gift is one of life’s greater challenges, modestly more difficult than earning a Ph.D. in astrophysics. So it is time for my annual gift guide.
For starters, the Web sites of the major humanitarian organizations offer alluring holiday gifts. Through the International Rescue Committee, $30 buys a flock of chickens for a needy family. At CARE, $29 gets a girl a school uniform. Through Heifer International, you can stock a fish pond for $300. With Mercy Corps, $69 can start a female entrepreneur in the sewing business.
Beyond those organizations, here are some lesser-known charities that may help put a grin on Grandma — and on someone else.
Helen Keller International
fights blindness and malnutrition around the world with simple and cost-effective programs. One of the best ways to improve children’s health is to focus on micronutrients, like iodine, vitamin A and zinc — and in some cases to fortify foods with nutrients at a negligible cost. Helen Keller International, at hki.org, is a leader in that effort, and gets more bang for the buck than almost any group I can think of.
And those glasses I mentioned for a schoolchild? That’s a Helen Keller International program, ChildSight, which operates in the United States as well as in Indonesia and Vietnam. Schoolchildren are screened for vision problems, and those who need glasses get them. Providing glasses costs just $25 per child — which is a much better value than a sweater that will sit in a drawer for eternity.
12 Things You Didn’t Know Facebook Could Do
As the number of features grows, though, so does a corresponding problem: Most of Facebook’s 750 million users don’t know these features exist. Some don’t know how to find them, some don’t go hunting for them in Facebook’s ever-growing interface of controls and many don’t even think of them in the first place. A few minutes of exploration can uncover functions that make Facebook not just an addiction but a pleasure to use.
