A new vaccine can protect macaques against the monkey equivalent of HIV and could provide a fresh approach to an HIV vaccine, a study suggests.
US researchers say the vaccine offered protection to 13 of 24 rhesus macaques treated in the experiment.
In 12 of the monkeys, the vaccine was still effective 12 months later — via redwolf.newsvine.com

New research published by the University of California, Berkeley, shows that graphene — an incredibly thin and flexible form of carbon — can be used to boost the transmission and switching speed of optical modulators, the building blocks of routers that form the backbone of the internet.
Scientists at UC Berkeley, led by professor Xiang Zhang, have found that one-atom-thick layers of graphene can switch light on and off incredibly quickly. With just the right amount of positive voltage, graphene turns opaque, stopping any light from passing through — and with a negative voltage, graphene can be turned transparent again. The team then successfully shrunk a graphene optical modulator down to 25 square microns in size — small enough to include in silicon circuitry — and modulated it at a speed of 1GHz. The researchers say that modulation speeds of up to 500GHz are theoretically possible, though — and for comparison, the modulators found in 40Gbit switches are measured in centimeters and operate at just 40GHz — via redwolf.newsvine.com

I do so love to report these wins for reality, as rare as they are: the very vocal antivax advocate Mark Geier has had his medical license revoked in Maryland. Why?
The Maryland State Board of Physicians reviewed nine cases of autistic children seen by Geier, of which he treated seven. Of those nine, the Board found he misdiagnosed six of them — via redwolf.newsvine.com

The Architecture of Access to Scientific Knowledge from lessig on Vimeo.
Lecture at CERN, Geneva, Switzerland, 18 April 2011: A new talk about open access to academic or scientific information, with a bit of commentary about YouTube Copyright School.
Copyleft crusader and Harvard professor Larry Lessig gave a new talk at CERN last week about copyright and how it has affected open access to academic or scientific information, with a bit of commentary about YouTube Copyright School. As usual, it’s blistering commentary. It’s time to recognize that free access – as in ‘free’ as in speech access – is no fad, and it’s time to push this non-fad war broadly in the context of science,
