An HIV-positive man who received a stem cell transplant for leukemia has been cured of HIV infection, doctors announced recently.
While the case was first reported at the 2008 Conference on Retroviruses and Opportunistic Infections in Boston, doctors have now published an updated report in the journal Blood, which affirms extensive testing — via luckydog.newsvine.com

Researchers have identified two genetic variants that increase the risk of women developing endometriosis — via redwolf.newsvine.com
The tobacco mosaic virus is a destructive beast infecting over a hundred different species of plants, including tomatoes. But it may have a weird eco benefit: Incorporated into lithium batteries, it can increase storage capacity ten times — via redwolf.newsvine.com
US scientists have developed a self-healing material that uses a fibre optic nervous system
to detect and address cracks.
The material was expected to be used in large-scale composite structures for which human intervention would be difficult – for example, wind turbines, satellites, aircraft and the Mars Rover — via redwolf.newsvine.com
Caterpillars apparently can whistle, letting out squeaks that can fend off attacking birds, scientists have now found — via redwolf.newsvine.com
It’s one of Stonehenge’s greatest mysteries: How did Stone Age Britons move 45-ton slabs across dozens of miles to create the 4,500-year-old stone circle?
Now a new theory says that, while the ancient builders didn’t have wheels, they may well have had balls — via redwolf.newsvine.com
Biomimicry, or the emulation of nature to solve human problems, inspires some fascinating scientific research. Marine animals in particular are useful sources of information; last year, for example, MIT researchers began work on electronic screens and ink that use less than one hundredth the energy of traditional screens–and are based on the color-changing abilities of cuttlefish. Now the U.S. Department of Defense is giving a $6 million grant to researchers at Rice University and the Marine Biological Laboratory in Woods Hole for metamaterials
that mimic skin colors and patterns seen in sea creatures — via redwolf.newsvine.com
Scientists suggest people with Alzheimer’s disease clear a damaging protein from their brains more slowly than those who are healthy — via redwolf.newsvine.com
Just as air causes lift on the wings of an aeroplane, light can do the same trick, researchers have said.
The effect, first shown in simulations, was proven by showing it in action on tiny glass rods — via redwolf.newsvine.com
A US-British team of astronomers has discovered the first planet with ultra-high concentrations of carbon.
The researchers say their discovery supports the idea there may be carbon-rich, rocky planets whose terrains are made up of diamonds or graphite — via redwolf.newsvine.com
Imagine some buckshot from a shotgun got stuck in your chest or you had a radio transmitter stuck in your side. If you were a frog, your body might be pristine a few weeks afterward — they apparently have the remarkable ability to pee out foreign objects, with their bladders engulfing the intrusions to help get rid of such junk, scientists now find — via redwolf.newsvine.com
The Oriental hornet has a unique ability to harvest solar energy, scientists have discovered.
The large wasp species has a special structure in its abdomen that traps the sun’s rays, and a special pigment that harvests the energy they contain.
The discovery helps explain why these hornets have a large yellow stripe across their body and why they become more active as the day gets hotter.
It also changes our understanding of how insect metabolism can work — via jcatom.newsvine.com
A poll of 1,200 Australians to find out what issues people are most interested in has found science outranks sport — via redwolf.newsvine.com
For years we have been told to slip slop slap
to prevent skin cancer.
Now new Australian research has gone further, showing for the first time that daily sunblock use can prevent potentially deadly melanoma — via redwolf.newsvine.com
Taking a low-dose aspirin every day will reduce your chances of dying from cancer, scientists say today, confirming the over-the-counter pill as the most extraordinary drug yet discovered — via redwolf.newsvine.com
Archaeologists from the University of Chile have discovered a 12,000-year-old iron oxide mine in the north of the country — via redwolf.newsvine.com
Scientists are hailing a chemotherapy drug found to significantly increase the survival chances of child leukaemia patients whose cancer has returned — via redwolf.newsvine.com
What if you could be recognized by the way your eyes moved? An Israeli company believes that tracking the unique signatures in the movement of your eyeballs could be the most foolproof biometric system ever. What’s more, its setup could be used as a lie detector, or a drug and alcohol test — via redwolf.newsvine.com
Astronomers have discovered there are three times more stars in the universe than previously thought, boosting the likelihood of extraterrestrial life — via redwolf.newsvine.com
