‘Most Threatened’ Tribe Sees No Relief from Illegal Loggers | LiveScience

A deadline to remove illegal loggers and settlers from the lands of one of the most threatened tribes on Earth appears poised to pass without action in Brazil.

The Awá, a tribe of about 450, have won multiple legal battles granting them the rights to their territory, which are also guaranteed in the Brazilian constitution. But enforcement of those rights has been lacking, with reports of illegal logging camps operating only 3 miles (5 kilometers) from one Awá settlement.

“It’s a complete joke, really,” said Sarah Shenker, a Brazilian campaigner for Survival International, a group that advocates for the rights of indigenous people.

A judge, in a declaration published in March 2012, ordered the eviction of illegal loggers, settlers and ranchers from Awá land within a year. Even with the March 31 deadline approaching, no one has been removed.”

Nanoparticles Made From Bee Venom Can Kill HIV

"For the experiment, Wickline's team prepared free melittin and melittin-loaded nanoparticles and set them against various strains of HIV..."

“For the experiment, Wickline’s team prepared free melittin and melittin-loaded nanoparticles and set them against various strains of HIV…”

“… 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.”

Alberta aboriginal rock etchings defaced with drill, power washer, acid | Canada | News | National Post

native art destroyed

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.”

Another Alberta site containing aboriginal pictograms and petroglyphs was recently filled in with epoxy cement, while another blown up for use as gravel.

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.

New Hover Vehicle Recalls ‘Star Wars’ Bike – Yahoo! News

Hover vehicle similar to Star Wars' speeder bike

The aerial vehicle resembles a science fiction flying bike with two ducted rotors instead of wheels, but originates from a design abandoned in the 1960s because of stability and rollover problems. Aerofex, a California-based firm, fixed the stability issue by creating a mechanical system — controlled by two control bars at knee-level — that allows the vehicle to respond to a human pilot’s leaning movements and natural sense of balance.

“Think of it as lowering the threshold of flight, down to the domain of ATV’s (all-terrain vehicles),” said Mark De Roche, an aerospace engineer and founder of Aerofex.

Manta roller coaster

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.

Roving Curiosity: Why NASA’s Jaw Dropping Mars Mission Is Worth Every Penny – Technology – GOOD

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?

Could Bioremediation Turn Pacific Garbage Patch Into Habitable Island?

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.)
