New Hope of a Cure for H.I.V.

Medical researchers are again in pursuit of a goal they had all but abandoned: curing AIDS.

Until recently, the possibility seemed little more than wishful thinking. But the experiences of two patients now suggest to many scientists that it may be achievable.
One man, the so-called Berlin patient, apparently has cleared his H.I.V. infection, albeit by arduous bone marrow transplants.
More recently, a 50-year-old man in Trenton underwent a far less difficult gene therapy procedure. While he was not cured, his body was able to briefly control the virus after he stopped taking the usual antiviral drugs, something that is highly unusual.
“It’s hard to understate how the scientific community has swung in its thinking about the possibility that we can do this,” said Kevin Frost, chief executive of the Foundation for Aids Research, a nonprofit group. “Cure, in the context of H.I.V., had become almost a four-letter word.”

Apple’s AssistiveTouch Helps the Disabled Use a Smartphone

If you’re blind, you can literally turn the screen off and operate everything — do your e-mail, surf the Web, adjust settings, run apps — by tapping and letting the phone speak what you’re touching. You can also magnify the screen or reverse black for white (for better-contrast reading).
One new feature, called AssistiveTouch, is Apple’s accessibility team at its most creative. When you turn on this feature in Settings->General->Accessibility, a new, white circle appears at the bottom of the screen. It stays there all the time.
When you tap it, you get a floating on-screen palette. Its buttons trigger motions and gestures on the iPhone screen without requiring hand or multiple-finger movement. All you have to be able to do is tap with a single finger — even a stylus you’re holding in your teeth or fist.

Students Hack Microsoft’s Kinect to Assist the Visually Impaired

Two computer science students from the University of Pennsylvania, Eric Berdinis and Jeff Kiske, 3ybn0xws Students Hack Microsofts Kinect to Assist the Visually Impaired have hacked together a very impressive tactile feedback system for the visually impaired using a Microsoft Kinect device and a number of vibration actuators. The Kinecthesia is a belt worn camera system that detects the location and depth of objects in front of the wearer using depth information detected by the Kinect sensor. This information is processed on a BeagleBoard open computer platform and then used to drive six vibration motors located to the left, center and right of the user. The video below shows a demo of the system in use and gives a quick explanation of its operation.

Study Finds Signs of Awareness in 3 ‘Vegetative’ Patients

Three severely brain-injured people thought to be in an irreversible “vegetative” state showed signs of full consciousness when tested with a relatively inexpensive and commonly used method of measuring brain waves, doctors reported Wednesday. Experts said the findings, if replicated, would change standards in treating such patients.

Cell Study Finds a Way to Slow Ravages of Age

Having spent two years in a laboratory studying the mechanism of age related macular degneration, I have long suspected that the accumulation of toxins from senescent cells may be responsible for some of the devastating effects on vision which can happen in this condition. This study gives further credence to this idea...

Scientists may have found a way to put off some conditions of aging, according to a study in which they postponed or even prevented such afflictions as cataracts and wrinkle-inducing fat loss in mice by removing cells that had stopped dividing.
Researchers at the Mayo Clinic in Rochester, Minn., found for the first time that by using a drug to target and kill senescent cells, they could essentially freeze some aspects of the aging process.
Though the research, published Wednesday in the journal Nature, is in its very early stages, it suggests that senescent-cell clearance could be one path to staying healthy while aging.
When cells become senescent, they produce harmful compounds such as those that cause inflammation. Chronic tissue inflammation with aging is thought to underlie dementia, atherosclerosis and diabetes, among other ills, according to James Kirkland, head of Mayo's Center on Aging, who was also an author of the study.
In the study reported on Wednesday, the team used mice designed to age faster than normal and treated them with a drug that identifies cells that have stopped dividing. The drug then initiates the natural process that leads to cell death by puncturing the membranes of those cells alone.
The researchers treated some mice over the course of their lifetimes and found a "quite dramatic delay" in the development of cataracts and age-related changes to muscle and fat, Dr. van Deursen said.
