Beware of online "filters" that hide the information you need

Eli Pariser: Beware online "filter bubbles", TEDtalksDirector, May 2, 2011: As web companies strive to tailor their services (including news and search results) to our personal tastes, there's a dangerous unintended consequence: We get trapped in a "filter bubble" and don't get exposed to information that could challenge or broaden our worldview. Eli Pariser argues powerfully that this will ultimately prove to be bad for us and bad for democracy.

Similarly, you don't want Twitter to replace your RSS reader - always get to the original source. When you see a medical news item on Reuters or WebMD, don't stop there - always go to the original journal article. More often that not you will find that the results reported in the original article are a quite a bit more nuanced and less certain than the layman language, SEO-optimized headline that you first encountered. Always go to the source. If you write a blog, always link to the source.

The first part of the talk points to some eye-opening facts about how the current school system is failing boys.

Protecting the brain from concussion: $20-helmet is a good way to protect $100,000 education

Neuropsychologist Kim Gorgens makes the case for better protecting our brains against the risk of concussion -- with a compelling pitch for putting helmets on kids: A $20-helmet is a good way to protect $100,000 education. "Mind your (brain) matter."

Just consider the following tragic story:

Former NFL payer shot himself in chest so that his brain could remain intact for examination for encephalopathy

Before he shot himself fatally in the chest Thursday, the former Chicago Bears defensive back Dave Duerson sent family members text messages requesting that his brain tissue be examined for the same damage recently found in other retired players.

As a longtime force in the N.F.L. players union, Duerson, 50, was keenly aware of chronic traumatic encephalopathy, the degenerative brain disease linked to depression, dementia and occasionally suicide among more than a dozen deceased players. He had expressed concern in recent months that he might have had the condition.

“This thing has the whole union community pretty shaken up.”

After a lung transplant, an aria: a story of survival from end-stage pulmonary hypertension

TED talks: "You'll never sing again, said her doctor. But in a story from the very edge of medical possibility, operatic soprano Charity Tillemann-Dick tells a double story of survival -- of her body, from a double lung transplant -- and of her spirit, fueled by an unwavering will to sing. A powerful story from TEDMED 2011."

Tillemann-Dick was diagnosed in 2004 – at the age of 20 – with Idiopathic Pulmonary Hypertension, a disease that causes high blood pressure in the pulmonary artery, which connects the heart to the lungs. People with the disease typically have a two-to-five-year mortality rate after diagnosis.

Her physicians at Johns Hopkins put her on the lung transplant list at Cleveland Clinic. In September 2009, organs became available, and she had a double lung transplant. After a 13-hour surgery and 2 cardiac arrests in the OR, her recovery was extremely complicated but she is happy to be able to sing again.

How to succeed? Get more sleep

In this 4-minute talk, Arianna Huffington (founder of The Huffington Post) shares a small idea that can awaken much bigger ones: the power of a good night's sleep. Instead of bragging about our sleep deficits, she urges us to sleep our way to increased productivity and happiness -- and smarter decision-making.

Quotes from the talk:

"I was recently having dinner with a guy who bragged that he had only gotten four hours sleep the night before. And I felt like saying to him, "You know what? If you had gotten five, this dinner would have been a lot more interesting."

There is now a kind of sleep deprivation one-upmanship. Especially here in Washington, if you try to make a breakfast date, and you say, "How about eight o'clock?" they're likely to tell you, "Eight o'clock is too late for me, but that's okay, I can get a game of tennis in and do a few conference calls and meet you at eight." And they think that means that they are so incredibly busy and productive, but the truth is they're not."

"Microscopic cancers are forming in human body all the time"

From TEDtalksDirector — May 17, 2010 - William Li presents a new way to think about cancer treatment: angiogenesis, targeting the blood vessels that feed a tumor. The crucial first (and best) step: Eating cancer-fighting foods that beat cancer at its own game.

"We're probably forming microscopic cancers all the time in our body. Autopsy studies from people who died in car accidents have shown that about 40 percent of women between the ages of 40 and 50 actually have microscopic cancers in their breasts. About 50 percent of men in their 50s and 60s have microscopic prostate cancers. And virtually 100 percent of us, by the time we reach our 70s, will have microscopic cancers growing in our thyroid. Yet, without a blood supply, most of these cancers will never become dangerous. Dr. Judah Folkman, who was my mentor, and who was the pioneer of the angiogenesis field, once called this "cancer without disease."

Collective patient data has power to comfort, explain and predict - TED video

"When Jamie Heywood's brother was diagnosed with ALS, he devoted his life to fighting the disease as well. The Heywood brothers built an ingenious website where people share and track data on their illnesses -- and they discovered that the collective data had enormous power to comfort, explain and predict." TED Talks.

TED Talks: The giant hospital on the hill is "mainframe healthcare" - a relic from the last century

At TEDMED, Eric Dishman makes a bold argument: The US health care system is like computing circa 1959, tethered to big, unwieldy central systems: hospitals, doctors, nursing homes. As our aging population booms, it's imperative, he says, to create personal, networked, home-based health care for all.

Geo-medicine: Your health may depends on where you live

Where you live: It impacts your health as much as diet and genes do, but it's not part of your medical records. At TEDMED, Bill Davenhall shows how overlooked government geo-data (from local heart-attack rates to toxic dumpsite info) can mesh with mobile GPS apps to keep doctors in the loop. Call it "geo-medicine."
