Interesting article in the Economist predicting the decline of the efficacy of doctors in an increasingly wired world with a growing, graying population:

“The past 150 years have been a golden age for doctors. In some ways, their job is much as it has been for millennia: they examine patients, diagnose their ailments and try to make them better. Since the mid-19th century, however, they have enjoyed new eminence. The rise of doctors’ associations and medical schools helped separate doctors from quacks. Licensing and prescribing laws enshrined their status. And as understanding, technology and technique evolved, doctors became more effective, able to diagnose consistently, treat effectively and advise on public-health interventions—such as hygiene and vaccination—that actually worked.

This has brought rewards. In developed countries, excluding America, doctors with no speciality earn about twice the income of the average worker, according to McKinsey, a consultancy. America’s specialist doctors earn ten times America’s average wage. A medical degree is a universal badge of respectability. Others make a living. Doctors save lives, too.

With the 21st century certain to see soaring demand for health care, the doctors’ star might seem in the ascendant still. By 2030, 22% of people in the OECD club of rich countries will be 65 or older, nearly double the share in 1990. China will catch up just six years later. About half of American adults already have a chronic condition, such as diabetes or hypertension, and as the world becomes richer the diseases of the rich spread farther. In the slums of Calcutta, infectious diseases claim the young; for middle-aged adults, heart disease and cancer are the most common killers. Last year the United Nations held a summit on health (only the second in its history) that gave warning about the rising toll of chronic disease worldwide.

But this demand for health care looks unlikely to be met by doctors in the way the past century’s was.”

“Man…woman…birth…death…infinity”:

From an L.A. Times piece about the C-1, a self-balancing, enclosed, electric motorcycle from Lit Motors.

“Lit Motors calls it the C-1, but the San Francisco start-up’s untippable motorcycle seems nothing short of magic. It uses gyroscopes to stay balanced in a straight line and in turns in which drivers can, in theory, roll down their windows and drag their knuckles on the ground.

Is it a motorcycle? A car? Neither. It’s an entirely new form of personal transportation, presuming it gets off the ground.

The all-electric vehicle is fully enclosed and uses a steering wheel and floor pedals like a car. But it weighs just 800 pounds and balances on two wheels even when stopped, making it more efficient than hauling around a 2-ton four-wheeler and safer than an accident-prone bike.”

A needleless injection system, just patented by MIT, delivers medicine to the bloodstream through a hypospray. From Dvice: “MIT has developed an injection system that uses a powerful magnetic piston to push a near-supersonic dose of medication straight through your skin into your body. The drugs themselves are carried along on a blast of air that’s skinnier than the proboscis of a mosquito, which means that you can’t feel it at all. In fact, it doesn’t even leave a mark, which means that it can be used on your eardrums or even your eyeballs without causing any damage.”

MIT reaserchers have created a low-cost virtual-reality system. From Cult of Mac: “Not only can you reach into the virtual world and manipulate the objects you create there, but there’s a way to connect with others, locally or remotely, to collaborate within a shared 3D virtual space. Looks like all that virtual reality stuff from the late 1990s is coming around again, only with the iPad, an off-the-shelf computing system with plenty of power for this application.”
