How scientists built the world’s first lab-grown limbs

Harald Ott spent weeks in a lab tending to a tiny rat’s forelimb. He got a special incubator for it, monitored it daily, cared for its every need.
The reason a rat leg was worth all that work? There was no rat attached to it.
Ott, a researcher and thoracic surgeon at Massachusetts General Hospital, is the proud parent of the world’s first lab-grown biolimb — a living, functioning, artificial leg that responds to stimuli and even circulates blood,  the hospital announced Tuesday. Though it’s still a long way off from made-to-order transplants for humans, Ott and other regeneration experts say that the tiny pink rat leg is a step toward the future of artificial limbs.
“This is science fiction coming to life,” Daniel Weiss, a lung regeneration specialist at the University of Vermont College of Medicine, told the New Scientist.

Smart Glove to Guide Blind People Inside Grocery Stores

Researchers at Penn State are working on a smart glove that can help blind people shop at the grocery store. The idea came because figuring out what items are on the shelves is a major limitation blind people report as wanting to be able to overcome. There are products in existence that can scan bar codes and tell you what’s inside the package, but they depend on the bar code facing the camera or laser used to scan it. The other problem is that these products don’t help you find what you’re looking for, but simply verify that what you’re holding is the right thing.

Pixium Vision Implants Restore Sight in Rats with Retinal Degeneration, Humans Next (VIDEO)

Prima Vision, a company based in Paris, France, is reporting that its PRIMA wireless subretinal implants for people who lost their vision has show a great deal of promise in a pre-clinical trial. The technology is designed specifically for those whose natural photoreceptors no longer function, yet who retain retinal neurons that can be electrically activated. A bunch of the implants are injected into the back of the eye, each around 70-μm in width that represents a single pixel. The implants are basically tiny photovoltaic solar panels that emit electricity in response to light hitting their surface.

ABOUT once a month I run across a person who radiates an inner light. These people can be in any walk of life. They seem deeply good. They listen well. They make you feel funny and valued. You often catch them looking after other people and as they do so their laugh is musical and their manner is infused with gratitude. They are not thinking about what wonderful work they are doing. They are not thinking about themselves at all.
When I meet such a person it brightens my whole day. But I confess I often have a sadder thought: It occurs to me that I’ve achieved a decent level of career success, but I have not achieved that. I have not achieved that generosity of spirit, or that depth of character.

Will Your Child Become Nearsighted? One Simple Way To Find Out

This is for everyone whose parents said, "Sitting too close to the TV is going to ruin your eyes." In other words, pretty much all of us.
Sitting too close to the TV doesn't predict nearsightedness, according to a study that tracked the vision of thousands of children over 20 years. Nor does doing a lot of close work.
Instead, as early as age 6 a child's refractive error — the measurements used for an eyeglass prescription — best predicts the risk.

How $5000 surgery can permanently change brown eyes to blue

In the classic 1930s movie, "The Wizard of Oz," Dorothy asks the good citizens of Oz whether they could dye her eyes to match her gown, and they happily oblige. Of course, eyes are not like hair, and 75 years on you still cannot dye your eyes to suit your outfit. But it turns out that you can actually change their color with the aid of a laser.
The technique was pioneered by California-based Stroma Medical and it is currently available in several countries, but it has yet to receive approval in the United States. So far,37 patients in Mexico and Costa Rica have undergone the procedure, which permanently turned their eyes from brown to blue.
