Is there really an epidemic of teens taking ADHD drugs to get good grades?

students

Data shows clearly that we are not even close to the all time peak of misuse of prescription stimulants by high-school students.

According to a front page story in Sunday’s New York Times, there’s an epidemic in America’s selective high schools: high-achieving students under pressure to succeed are increasingly abusing stimulants like Ritalin and Adderall, which they consider as essential as SAT tutors for getting into an Ivy League college.  But the data from national surveys on stimulant use tells a very different story.

41% of young adults skip health care as medical costs rise

medical-debt

41% of young adults between age 19 and 29 failed to get medical care in a recent 12-month period because of cost.

There are millions of young adults who are skipping necessary care and treatment because of rising health care costs in the U.S., according to a new report released on Friday.

Mobile health apps just the beginning of the disruption in healthcare

The potential of government making health information as useful as weather data felt like an abstraction two years ago. Healthcare data could give citizens the same “blue dot” for navigating health and illness akin to the one GPS data fuels on the glowing map of geolocated mobile devices that are in more and more hands.

Science may have just beaten Prostate Cancer

Did we win this battle?
How do you know when your new cancer drug is working better than expected? When they shut down the clinical trial so that every participating patient can receive it.

Johnson & Johnson’s Zytiga is kind of a big deal. The FDA approved its use last year for advanced prostate cancer patients who had already received chemo but whose cancer had still metastasized. Prostate cancer is typically treatable for the 200,000 American men who contract it annually, as long as it is caught before it spreads…

Play-a-Grill lets you hear music through your teeth

Would you use a tongue-controlled MP3 grill?

Ever since Zeon took a hammer to my boombox, I haven’t been able to rock out to my favorite New Kids on the Block tunes at work. Aisen Caro Chacin’s invention may prove to be an acceptable alternative. Her tongue-controlled MP3 player uses the palate to carry sound to the ears…

Rapid DNA sequencing could soon become a routine part of your medical record

DNA sequencing

The latest technological competition involves the idea of threading a single strand of DNA through a tiny, molecular-scale eyelet known as a nanopore.

Rapid DNA sequencing can provide enormous amount of information previously sequestered in the human genome’s 3 billion nucleotide bases and soon may become a routine part of each individual’s medical record.

Scientists restore sight to blind mice by regenerating optic nerve

Scientists restore vision to blind mice.

There are three blind men who have an inherited eye disorder that had destroyed the light-sensing cells of their retinas many years ago.  Now one of the blind men can walk around at night navigating by streetlight and headlights.  Another can read his own name.  And the third mean has been able to see his fiancée’s smile for the very first time.  All of this has been made possible by the retinal implants they have been fitted with.  The implants took over from the broken cells.  They sense incoming light by converting it into electrical impulses delivered to the brain.  They aren’t close to having 20/20 vision, but they have restored sight to people who have lived without it for years.

How Private Is Your DNA?

DNA privacy

How is my DNA NOT private?

Unlike the contents of your inbox, bank statement, or Facebook timeline, your DNA quite literally defines you. It’s strange, then, that in an age where sequencing the genome is becoming trivial, we don’t give a second thought about the privacy issues surrounding the chemicals that make us who we are.

In fact, most states in the US have absolutely no laws whatsoever to govern surreptitious genetic testing. If that surprises you, it gets worse. Back in 2006, the particularly forward-thinking state of Minnesota passed a law demanding that written consent had to be obtained for collection, storage, use, and sharing of genetic information. In 2011, however, the Minnesota Supreme Court judged that the state’s own department of health was in violation of that very law.

So, quite literally millions of US citizen have their DNA records stored on databases, and there are few laws governing what’s done with the data. Something has to be done about that—but it’s not necessarily as easy as it sounds.

Clamp down on DNA privacy…

How deadly charcoal is bought and sold in an African market

Charcoal for sale in an African market.

Xipamanine is a sprawling, labyrinthine marketplace in the heart of Maputo, Mozambique’s capital. On the street outside, tinny music blares and a bustling throng mills around. Inside, a series of winding corridors leads you through a maze of colorful booths that boast a wide variety of wares: shoes, stereo equipment, coconuts, toys, tomatoes, rugs, seeds, nuts, goats, and charcoal. Lots of charcoal.

You can buy it wholesale, in a gigantic sack with a month’s worth of cooking fuel, for about $20. An entire open air section of the market is dedicated to storing these bags; they’re stacked in imposing dust-covered piles….

What you need to know about what’s inside those breasts

Breasts are getting bigger and arriving earlier. They’re also attracting chemicals and environmental toxins, which are getting passed along in breast milk.

Writer Florence Williams read a research study about toxins found in human breast milk when she was nursing her second child. After reading the study she decided to test her own breast milk and shipped a sample to a lab in Germany.

Why Creative People Are Eccentric

Ibot Dean Kamen

Dean Kamen on his Ibot invention.

He is one of the world’s best known and most successful entrepreneurs, with hundreds of patents to his name—including the Segway scooter. But you will never see Dean Kamen in a suit and tie: the eccentric inventor dresses almost exclusively in denim. He spent five years in college before dropping out, does not take vacations and has never married. Kamen presides (along with his Ministers of Ice Cream, Brunch and Nepotism) over the Connecticut island kingdom of North Dumpling, which has “seceded” from the U.S. and dispenses its own currency in units of pi. Visitors are issued a visa form that includes spaces on which to note identifying marks on both their face and buttocks…
