US Air Force Selects Boeing 747-8 To Replace Air Force One

Slashdot - Thu, 29/01/2015 - 8:46pm
Tyketto writes Following up on a previous story about its replacement, the US Air Force has selected the Boeing 747-8 to replace the aging Presidential fleet of two VC-25s, which are converted B747-200s. With the only other suitable aircraft being the Airbus A380, the USAF cited Boeing's 50-year history of building presidential aircraft as their reason to skip competition and opt directly for the aircraft, which due to dwindling sales and prospects, may be the last 747s to be produced.

In a role reversal, RNAs proofread themselves

Science Daily - Thu, 29/01/2015 - 8:16pm
Building a protein is a lot like a game of telephone: information is passed along from one messenger to another, creating the potential for errors. Enzymatic machines proofread at each step, and scientists have uncovered a new quality control mechanism along this path. But in a remarkable role reversal, the proofreading isn't done by an enzyme. Instead, one of the messengers itself has a built-in mechanism to prevent errors.

Ask Slashdot: When and How Did Europe Leapfrog the US For Internet Access?

Slashdot - Thu, 29/01/2015 - 7:50pm
New submitter rsanford, apropos of today's FCC announcement about what is officially consided "broadband" speed by that agency, asks In the early and middle 90's I recall spending countless hours on IRC 'Trout-slapping' people in #hottub and engaging in channel wars. The people from Europe were always complaining about how slow their internet was and there was no choice. This was odd to me, who at the time had 3 local ISPs to choose from, all offering the fastest modem connections at the time, while living in rural America 60 miles away from the nearest city with 1,000 or more people. Was that the reality back then? If so, what changed, and when?

When Robots Beam Down From the Cloud

Wired News - Thu, 29/01/2015 - 7:42pm

It’s been over 20 years since Larry Ellison made the case for cloud computing. Some speculate he only invented the idea to get at Bill Gates, the dominance of the PC and the then-newly released Windows 95. Even if the motivation had a personal edge, the point is that he had a strong case. As […]
