New Vaccine Could Turn HIV Into Minor Infection | Fox News:
'via Blog this'
A powerful new vaccine developed by Spanish scientists could turn HIV into a minor infection such as herpes, according to a study out Thursday.
In a trial involving 30 healthy volunteers, scientists found that 90 percent of those who were given the MVA-B vaccine developed an immunity against the virus and 85 percent maintained this for a year.
The vaccine, developed by scientists at the Spanish Superior Scientific Research Council (CSIC) in Madrid, works by training the immune system to detect HIV and learn how to combat the virus.

In tests for the drug, mice given the drug did not even display signs of getting tipsy, despite being fed enough alcohol to make them stumble and fall over.
The research paves the way for a tablet that stops people embarrassing themelves on nights out.
It could help explain why some drinkers are "cheap dates" who start slurring their words and losing their inhibitions after one glass of wine, while others can knock back glass after glass with few ill effects.

A single high dose of the hallucinogen psilocybin, the active ingredient in so-called "magic mushrooms," was enough to bring about a measurable personality change lasting at least a year in nearly 60 percent of the 51 participants in a new study, according to the Johns Hopkins researchers who conducted it.

Testing gravity is simple: walk out of a second-floor window and see what happens. It’s a lot tougher to test Albert Einstein’s theory of gravity — the general theory of relativity — which says that the gravity of an object warps space and time around it. Although researchers have proved general relativity on the scale of the solar system, validating it on cosmic scales has been more challenging. That’s exactly what a group of astrophysicists in Denmark have now done.

In 1929, cosmologists discovered that the universe is expanding — that space-time, the fabric of the cosmos, is stretching. Then in 1998, light coming from exploding stars called supernovas suggested that the universe is not only expanding, but that it has recently begun expanding faster and faster; its expansion has entered an "accelerating phase." This was bad news for the fate of the cosmos: An accelerating universe is ultimately racing toward a "Big Rip," the moment at which its size will become infinite and, in a flash, everything in it will be torn apart.

It's only September, but humans have used up the Earth's natural resources for the year, according to a sustainability nonprofit group.
The Global Footprint Network (GFN) has declared today (Sept. 27) "Earth Overshoot Day." That's the day when humankind's demand on nature exceeds the planet's ability to regenerate resources and absorb the waste.
"Our research shows that in approximately nine months, we have demanded a level of services from nature equivalent to what the planet can provide for all of 2012," according to a GFN statement. "We maintain this deficit by depleting stocks of things like fish and trees, and by accumulating waste such as carbon dioxide in the atmosphere and the ocean."

'via Blog this'
Like a computer the brain works best when it is cool, but putting too great a strain on it can lead to overheating which reduces its ability to process information.
When the head begins to heat up, yawning acts as a natural "thermostat" by allowing cool air to rush in and bring the brain back down to a healthy temperature, research suggests.
A study of 160 volunteers in Arizona found that people yawned almost twice as much in winter, when their body temperature was higher than the air around them, than in summer.

The compound, found in the liver of the predator, could be used as a new type of drug to treat a broad spectrum of diseases from dengue and yellow fever to hepatitis B, C and D.
The antibiotic, squalamine, is already known to be safe for use in humans as an antiviral agent.

Babies and psychopaths have one thing in common: They're excellent at getting what they want. Many of us could learn a thing or two from these creatures, tantrums and dirty tactics notwithstanding. That's not to say that, like these ingrates, we should feel entitled to everything we want. Many argue that as a culture, we need urgent lessons in giving, not getting.
But for some, grabbing the brass ring is a constant source of stress and confusion. Others have no trouble going for what they want, but fail to do so effectively. Conflict-avoidant people are terrified to speak up—they miss out on their own objectives, and often forfeit the respect of those around them. Conflict seekers get a thrill from relentlessly asserting their agendas, even to their own detriment. Optimists are more likely to persist in their efforts than are pessimists, who may underestimate their odds of success at the outset.
