Scientists have for some years been able to ‘teleport’ quantum states from one place to another. Now Seth Lloyd and his MIT team say that, using the same principles and a further strange quantum effect known as ‘postselection’, it should be possible to do the same backwards in time. Lloyd told the Technology Review: “It is possible for particles (and, in principle, people) to tunnel from the future to the past.”
And that brings up a few points (and — don’t forget/as always — I’m nothing more than an enthusiastic amateur with this):
1. Can we make quantum mechanics nonlinear?
2. How does postselection get around the idea of twisting space and time?
3. The website on which the original paper appeared is not peer-reviewed. (Sadly.)

“The bill takes a few shuffling steps in that direction. It calls on the Energy Department to create a national plan for deploying electric vehicles. It allows electricity to count as an alternative vehicle fuel. It provides grants to local communities that set up their own plug-in networks. It also calls for a whole flurry of studies on things like identifying the raw materials needed for plug-in technology (no doubt with an eye on China’s announcement that it will cut exports for rare-earth metals like lithium, which are crucial for batteries). All told, there’s only $400 million in the bill for electrification, compared with $6 billion in tax incentives for the purchase of natural-gas vehicles. Still, it’s a start.”

The idea of cutting the Film Council irked me a bit today, so I scribbled down some alternative ideas of what the cut-hungry government across the pond is also considering:
Here’s a petition to save the Film Council and here’s a facebook group.
UK Film Council axed without notice or consultation.
The council helped fund In The Loop, Man on Wire, Bright Star, Red Road, Happy-Go-Lucky, and did much more.
