Poachers kill last female rhino in South African park
South African wildlife experts are calling for urgent action against poachers after the last female rhinoceros in a popular game reserve near Johannesburg bled to death after having its horn hacked off. Wildlife officials say poaching for the prized horns has now reached an all-time high. "Last year, 129 rhinos were killed for their horns in South Africa. This year, we have already had 136 deaths," said Japie Mostert, chief game ranger at the 1,500-hectare Krugersdorp game reserve.

In Politics, Sometimes The Facts Don't Matter
 From NPR - New research suggests that misinformed people rarely change their minds when presented with the facts -- and often become even more attached to their beliefs. The finding raises questions about a key principle of a strong democracy: that a well-informed electorate is best.

Poof! After Wireless, the Computer Mouse Turns Invisible
In a magic trick that only geeks can pull off, researchers at MIT have found a method to let users click and scroll exactly the same way they would with a computer mouse, without the device actually being there.
Cup your palm, move it around on a table and a cursor on the screen hovers. Tap on the table like you would click a real mouse, and the computer responds. It’s one step beyond cordless. It’s an invisible mouse.
The project, called “Mouseless,” uses an infrared laser beam and camera to track the movements of the palm and fingers and translate them into computer commands.

Hair Keeps Chemical Record of Where You've Been
 In one cold case, the team was brought in to help identify the body of a 20-something woman who was found dead of stab wounds in 1971, but whose case remained unsolved. After analyzing the isotopes in her hair, the scientists were able to conclude that the woman had lived (and therefore drunk tap water and other beverages) in Northern California for at least 18 months before she died. That clue helped detectives focus their search.With the help of missing persons records, DNA and other types of evidence, they were finally able to identify her as Mary Alice Willey -- providing, at least, some finality for family members and opening the possibility that her killer might be found.

Humans Will Be Extinct Within 100 Years
Is the clock of doom ticking for mankind? Yes, says an eminent 95 year old scientist from Australia. Professor Frank Fenner -- the same scientist who brought the myxomatosis virus to rabbits to control their numbers in the 1950's -- is acutely aware of the impact of overpopulation and shortage of resources.
In an interview with The Australian, the well-respected microbiologist expressed his pessimism for our future. "We're going to become extinct," he said. "Whatever we do now is too late."

Scientists Teleport Info 10 Miles
 We may never be able to teleport ourselves "Star Trek"-style, but scientists managed to transmit information a record distance using entangled photons. Teleported telephone call would be impenetrable. Unlike radio waves, which send out a signal that enemies can pick out, eavesdropping on a teleported telephone call would be impossible. The two particles are entangled with themselves and no other particle so the quantum mechanical equations simply do not allow it, said Schumacher.

Headless Gladiator Graveyard Unearthed
 One of the most significant items of evidence is a large carnivore bite mark -- probably inflicted by a lion, tiger or bear -- an injury which must have been sustained in an arena context, said Kurt Hunter-Mann, who is leading the investigation.
Many of the skeletons also had one arm that was stronger than the other, consistent with the frequent handling of a weapon.

Giant Gravel Batteries Could Make Wind Power a Reliable Energy Option
Wind power is green as can be, but incredibly inconsistent. A new gravel-battery storage scheme could cheaply store excess power when the wind is strong to supplement wind turbines when the gusts die down.

A New Clue to Explain Existence
According to the basic precepts of Einsteinian relativity and quantum mechanics, equal amounts of matter and antimatter should have been created in the Big Bang and then immediately annihilated each other in a blaze of lethal energy, leaving a big fat goose egg with which to make stars, galaxies and us. And yet we exist, and physicists (among others) would dearly like to know why.

Obese, gluttonous, and cannibalistic is no way to go through life, son
Astronomers have found a bloated, massive galaxy that may be a record-breaker: the most massive galaxy in the near Universe. The mass isn’t exactly clear, but it may be 13 trillion times the mass of the Sun!*

Texas schools board rewrites US history with lessons promoting God and guns
The board is to vote on a sweeping purge of alleged liberal bias in Texas school textbooks in favour of what Dunbar says really matters: a belief in America as a nation chosen by God as a beacon to the world, and free enterprise as the cornerstone of liberty and democracy.

College for all? A good Idea?
This graduation season, some experts challenge whether four-year degree is path to success. The notion that a four-year degree is essential for real success is being challenged by a growing number of economists, policy analysts and academics. They say more Americans should consider other options such as technical training or two-year schools, which have been embraced in Europe for decades.

NIST Digital Library of Mathematical Functions
The project had two equally important goals: to develop an authoritative replacement for the highly successful Handbook of Mathematical Functions with Formulas, Graphs, and Mathematical Tables, published in 1964 by the National Bureau of Standards (M. Abramowitz and I. A. Stegun, editors); and to disseminate essentially the same information from a public Web site operated by NIST.

Why boys are turning into girls
Here's something rather rotten from the State of Denmark. Its government yesterday unveiled official research showing that two-year-old children are at risk from a bewildering array of gender-bending chemicals in such everyday items as waterproof clothes, rubber boots, bed linen, food, nappies, sunscreen lotion and moisturising cream.

I spend a lot of time on the
net and every once in a while I see something that is just so cool, I just
have to write it down. I recently combined this with my interest in
software at the right price (Free). I set up Really Simple Syndication (RSS)
on the ExReps site as a way of keeping track of this stuff, and to share it
with the other ExReps.
