Two suspected exoplanets,
Gliese 581g and 581d, have been shown to not exist, and are instead
misinterpretations of data from starspot activity. From the article:
"Gliese 581g doesn't exist," said lead author Paul Robertson of Penn State University in State College, Pennsylvania. Neither, he said, does another planet in the same solar system, known as Gliese 581d, announced in 2009—less clearly hospitable to life, but still once seen by some astronomers as a possible place to find aliens. ... What's happening, they say, is that magnetic disturbances on Gliese 581's surface — starspots — are altering the star's spectrum in such a way that it mimics the motion induced by a planet. The star itself rotates once every 130 days, carrying the starspots with it; the disputed planets appeared to have periods of almost exactly one half and one fourth of the 130-day period. When the scientists corrected for the starspot signal, both planets disappeared.Read Replies (0)

One of the common problems of the smartphone generation has been parents who given their phones to children, who then rack up hundreds of dollars of in-app purchases without the parents' knowledge. The FTC smacked Apple with a fine for this, and Google is facing a lawsuit as well. Now, Amazon is the latest target, having received a complaint from the FTC demanding a similar settlement to Apple's. Amazon, however, is not willing to concede the fine; they plan to fight it. Amazon said, "The Commission's unwillingness to depart from the precedent it set with Apple despite our very different facts leaves us no choice but to defend our approach in court (PDF). The main claim in the draft complaint is that we failed to get customers' informed consent to in-app charges made by children and did not address that problem quickly or effectively enough in response to customer complaints. We have continually improved our experience since launch, but even at launch, when customers told us their kids had made purchases they didn't want, we refunded those purchases."Read Replies (0)

As reported by the Sydney Morning Herald, NASA has
given a green light to the production of a new motor, dubbed the Space Launch System, intended to enable deep space exploration.
Boeing, prime contractor on the rocket, announced on Wednesday that it had completed a critical design review and finalized a $US2.8-billion contract with NASA. The last time the space agency made such an assessment of a deep-space rocket was the mighty Saturn V, which took astronauts to the moon. ... Space Launch System's design called for the integration of existing hardware, spurring criticism that it's a "Frankenstein rocket," with much of it assembled from already developed technology. For instance, its two rocket boosters are advanced versions of the Space Shuttle boosters, and a cryogenic propulsion stage is based on the motor of a rocket often used by the Air Force. The Space Frontier Foundation, an advocacy group and frequent NASA critic, said Space Launch System was "built from rotting remnants of left over congressional pork. And its budgetary footprints will stamp out all the missions it is supposed to carry, kill our astronaut program and destroy science and technology projects throughout NASA."Read Replies (0)

TechWeek Europe reports that on Friday Russia's parliament passed a law "which
bans online businesses from storing personal data of Russian citizens on servers located abroad[.] ... According to ITAR-TAAS, the changes to existing legislation will come into effect in September 2016, and apply to email services, social networks and search engines, including the likes of Facebook and Google. Domain names or net addresses not complying with regulations will be put on a blacklist maintained by Roskomnadzor (the Federal Supervision Agency for Information Technologies and Communications), the organisation which already has the powers to take down websites suspected of copyright infringement without a court order. In the case of non-compliance, Roskomnadzor will be able to impose 'sanctions,' and even instruct local Internet Service Providers (ISPs) to cut off access to the offending resource." According to the article, the "measure is widely seen as a response to reports about the intrusive surveillance practices of the US National Security Agency (NSA) and the UK’s GCHQ. Edward Snowden, who revealed sensitive data about the operations of both, is currently residing in Russia, with his asylum application up for a review in a couple of months." The writer points out that this would mean many web sites would be legally unavailable altogether to Russian users.
