TASER announces wildlife management stungun
By Noel McKeegan
We've seen TASER electroshock weapons designed for law enforcement, personal protection and even riot control, but in all of the above cases, it's a human on the receiving end. Now the company has a different target in sight for its "less lethal" technology ... and it's one that could create as much controversy as its predecessors – the TASER Wildlife Electronic Control Device (ECD).

Axolotl eggs could provide a potent weapon in fight against cancer
By Darren Quick
A common cause of cancer is when cells are altered or mutated and the body’s tumor suppressor genes are switched off. Scientists at the University of Nottingham have managed to bring cancer cells back under control by reactivating the cells’ cancer suppressor genes using an extract from axolotl oocytes. The scientists say the discovery could form a powerful new technology platform for the treatment of a variety of cancers.
The process of cell division is controlled by specific genes and these are turned “on” or “off” depending on their function. Among the most important of these genes are tumor suppressor genes. These genes repress the development of cancers and normally act as a control point in the cell division cycle. Therefore, the switching off of tumor suppressor genes is a common cause of cancers.

New Type Of Entanglement Allows 'Teleportation in Time,' Say Physicists
Conventional entanglement links particles across space. Now physicists say a similar effect links particles through time.
Entanglement is the strange quantum phenomenon in which two or more particles become so deeply linked that they share the same existence.
That leads to some counterintuitive effects, in particular, when two entangled particles become widely separated. When that happens, a measurement on one immediately influences the other, regardless of the distance between them. This "spooky-action-at-a-distance" has profound implications about the nature of reality but a clear understanding of it still eludes physicists.
Today, they have something else to puzzle over. Jay Olson and Timothy Ralph at the University of Queensland in Australia say they've discovered a new type of entanglement that extends, not through space, but through time.

The Dream Chaser will go into orbit on the nose of a rocket, then land gently on airport runways.
By Katherine Bourzac
Once the space-shuttle program ends this year, the only way to get people into orbit and to the International Space Station will be to buy seats on Russia's three-person Soyuz capsules. So NASA, through its Commercial Crew Development program, has given $50 million in grants to companies developing new spacecraft capable of carrying people and supplies into orbit and to the space station.
The recipient of the biggest chunk of this money was the Sierra Nevada Corporation, which received $20 million to develop the Dream Chaser. This spacecraft, the size of a business jet, will take cargo and up to eight people into low Earth orbit, where the space station is located, and then return and land on commercial airport runways.
