“… researchers from Washington University School of Medicine in St. Louis have shown that nanoparticles infused with a toxic bee venom can kill HIV. The researchers hope to take this new compound and develop a vaginal gel that can prevent the further spread of the disease.
The key to this discovery, which was made by Samuel A. Wickline and his team at Washington University, involves cytolyic melittin peptides. Melittin is found in bee venom, and it has the fortuitous trait of being able to degrade the protective envelope that surrounds HIV.”
It’s been twenty-two days since I last played. Clearly, I’ve suffered some atrophy. Bad kitty! Lol
Alberta aboriginal rock etchings defaced with drill, power washer, acid | Canada | News | National Post
The attack likely took place at night, to avoid being seen by nearby Hutterite farmers on whose property the rock sits, after being dropped there by a retreating glacier in the prehistoric past.
A power washer was apparently used to strip off the lichen to reveal the carvings and stained symbols. It appears acid was then sprayed to scorch off the painted images and destroy its value for date testing, Mr. Knowlton said.
A rock bore or hammer drill was used to repeatedly drill out the rock to obscure the carvings.
To do all of that would have required more than one person, a power generator, a pressure washer with a 100-litre water tank, a 1-1/2-inch electric hammer drill, appropriate bits, access to acid or a similar industrial-strength chemical, lights, ladders and a heavy truck, he said.
“It seems a deliberate effort,” said Mr. Knowlton. “This isn’t a theft or simple vandalism.”
In a different type of incident, a rare dinosaur skeleton found near Grande Prairie was destroyed by vandals who had “smashed indiscriminately” the fossilized bones of the Hadrosaur, scientists involved in the dig said.
This is inexcusable and absolutely disgusting. I hope the cowards are caught and prosecuted to the fullest extent of the law.
About Orbital Objects
The skies above Earth are teeming with manmade objects large and small. The U.S. Space Surveillance Network uses radar to track more than 13,000 such items that are larger than four inches (ten centimeters). This celestial clutter includes everything from the International Space Station (ISS) and the Hubble Space Telescope to defunct satellites, rocket stages, or nuts and bolts left behind by astronauts. And there are millions of smaller, harder-to-track objects such as flecks of paint and bits of plastic.
Gravitational pull will ensure that anything we’ve ever put in orbit will eventually make its way back to Earth. And though thus far no one has ever been killed by reentering space debris, NASA estimates on average one piece returns to Earth each day.
NASA and other national space agencies have identified orbital debris as a serious problem and are currently devising plans to mitigate existing space junk and curb future debris.

Flying over the half-mile course in our giant manta ray-shape ride car, we felt the exhilaration of pulling 3 to 4 G’s through more than a dozen twists and high-bank turns, and a thrilling 54-foot drop.
Whoo hoo! I do love a good roller coaster! ^_^
The week before, two friends of mine got into an argument. Brandon, excited for the landing, brought it up to Sam, who was decidedly not: “Pretty cool, but I wish they spent that money forgiving my student loans.” His law school debt was, in a different sense, astronomical.
Brandon bit back. “No offense, but I think that space exploration trumps having another blood sucking lawyer around.”
Sam didn’t flinch. “What’s the benefit? What have we gained from Mars or the moon? Why not spend the cash on other research–infectious diseases perhaps? Government has limited resources; If it spends money, the results must benefit the populace.”
Brandon was having a hard time articulating his point. “The benefit is exploring,” he said. “It’s to gain as much understanding of the universe.”
Sam was unconvinced. “That’s open-ended,” he said. “Exploring for shits and giggles should be left to the private sector. There’s got to be a benefit, otherwise the government should be spending the money on more pressing things.”
This argument occurs, year after year, at dinner parties and in Congress alike. Every time, someone asks the question: why are we paying for NASA? Why did we send Curiosity, at such enormous cost, when we’ve already sent three rovers? Why do we continue to spend billions on rovers and space telescopes and shuttles and space stations when there’s so much to fix here on earth? Just, why?
A research group out of University College London is proposing an unusually ambitious upcycling scheme—turning all that plastic junk swirling about the Pacific into a habitable island. The students aim to design and release a really tiny, genetically engineered, synthetic plastic-eating organism that could aggregate all those bottle caps, plastic bags, and broken toys into floating real estate or what they’ve called the “Plastic Republic.“

(Note: Personally I think calling it a “Patch” makes it smaller in people’s minds, and therefore nothing worrisome. This is wrong, because it needs as much attention as possible.)
