The technology to make starships work is still way off — but that isn’t stopping us from thinking about how it might work.

This is NOT the way to encourage people to use this device, nor develop anything for it at all. Shame on them!

The Oculus Rift is starting to ship, and we’re pretty happy with it. While it’s cool, like any interesting gadget, it’s worth looking through the Terms of Service, because there are some worrisome things included.
Quite a few of the items in the document are pretty typical in any sort of Terms of Service agreement. These include details like waiving your right to a juried trial and agreeing to go into arbitration instead. Oculus can also terminate your service for myriad reasons, and third parties can collect information on you. However, there are some even more devilish details in the Rift’s full Terms of Service.
Researchers of CWI, University of Gdansk, Gdansk University of Technology, Adam Mickiewicz University and the University of Cambridge have proven that quantum communication is based on nonlocality. They show that whenever quantum communication is more efficient than classical communication, it must be possible find a nonlocal correlation somewhere. Their paper ‘Quantum communication complexity advantage implies violation of a Bell inequality’, appeared in this month’s issue of the influential journal PNAS.
It has long been known that quantum mechanics predicts counterintuitive effects such as instantaneous interaction at a distance between entangled particles. This teleportation effect, which Albert Einstein famously called ‘spooky action at a distance,’ was long thought to show that the theory of quantum mechanics was incomplete. However, in 1964, physicist J.S. Bell proved that no theory involving the principle of locality can ever reproduce all predictions of quantum mechanics. In other words, it is impossible to find classical explanations for quantum correlations. This evidence for the existence of nonlocality became known as Bell’s inequality.
For a long time, the existence of quantum correlations was merely of interest to philosophically minded physicists, and was considered an exotic peculiarity rather than a useful resource for practical problems in physics or computer science. This has changed dramatically in recent years. Quantum correlation proved to be very useful in information processing. In several communication tasks, using quantum effects substantially reduced the communication complexity: the minimum number of steps necessary to complete a certain task between two parties. In such cases, there is a so-called quantum advantage in communication complexity.

Preliminary work suggests that T-cells, which normally target disease, can be genetically engineered to target senescent cells in a wide range of tissues. In future, an infusion of GM blood every few years might be able to keep you going indefinitely (assuming some major advances in treating cancer, Alzheimer’s and heart disease). At which point, the question might be less: “How long have I got?” and more: “How long do you fancy sticking around?”
American scientists have coined the term ‘senolytics’ to describe a new class of drugs designed to delay the ageing process by clearing out doddery cells.
