When Gizmodo alumnus and wonderful human Mat Honan got hacked, the point of entry for the hackers was through Amazon and Apple’s lax security policies. Amazon immediately admitted its fault in the situation and updated its security policy accordingly. Apple? Well, Apple still doesn’t know what do yet. More »

More than 15 percent of Mitt Romney’s Twitter followers may be generated by paid services that use fake accounts to artificially inflate the number of people subscribed to the presumptive Republican nominee for US president, according to a new report.
The report comes from researchers at security firm Barracuda Labs, and it cites the addition last month of 116,922 followers to @MittRomney in a span of just 24 hours. The infusion on July 21 represented a 17-percent spike in accounts following Romney. A quarter of those new accounts were less than four days old, and 23 percent of them had never issued a single tweet. Ten percent have since been suspended by Twitter for unspecified reasons.
“Based on the above distinguishable features, we believe most of these recent followers of Romney are not from a general Twitter population but most likely from a paid Twitter follower service,” Barracuda Labs Research Scientist Jason Ding wrote in the report. Such services allow customers to buy followers for any Twitter account, he stressed, so it’s not clear if the fakes were purchased by Romney, his supporters, or his political foes.

As much as we love our silicon semiconductors, quantum computers are very much a technology of the future. Instead of the usual string of 1s and 0s, they’ll be able to send both types of information at the same time, dwarfing their traditional counterparts. But one major problem is that they can only move through one optical fibre. To push more information through, they need a router, and Chinese physicists have unveiled the first one.
In a quantum computer, photons ferry information to other sources. It’s possible to send the photons directly through one fibre, but routing comes in when another fibre is needed. Like the router you probably own, a control signal reads the data then sends it to its destination. But dealing with unruly quantum particles is a little more complicated; when a signal is read it’s also destroyed. So even though the data can be transferred with traditional methods, that doesn’t offer the kind of data-transferring power quantum computing offers.
This new quantum router proves it’s possible to truly guide a quantum signal. The information used is encoded in two different types of polarized photons (like 1s and 0s). Scientists then create a single photon that acts as both (the combined 1s and 0s). That photon is then broken down into two photons that share the combined state. The router picks up one to determine the route, then the other photon is used to transfer the information. A simple series of half mirrors guides the photons along the correct route.
Does this mean we’re now well on our way to a globally connected, super-fast stream of information? No. The scientists say it’s just a proof of concept–we know it’s at least theoretically possible to send quantum information through a router, but it’s still a limited way of doing it. In other words, when this sort of technology is usable (and it will be), it won’t look like this.

While we in the U.S. wait with bated breath for Mars Rover Curiosity‘s August 5 landing on the red planet, India’s space program, the Indian Space Research Organisation, has confirmed that it plans to send an orbiter to Mars in 2013. It’s one small step in a program that’s been making giant leaps in recent years, including multiple satellite launch missions.
The total price tag for the project could wind up between $70 and $90 million, a source told AFP, which would go toward a 320-ton rocket carrying the orbiter. Once in place, it would study the planet’s climate and geology. That would already be a pretty big success for the program, but the ISRO is trying to go even further, planning to launch a fully manned mission by 2016.
India’s space program has been in place since the ’60s, but it’s in more recent years that its gained notoriety. In 2009, the country successfully launched seven satellites on a single rocket and it has been providing a cost efficient means of transporting satellites into space, but it was the Chandrayaan-1 lunar probe that brought the program global attention. Officials took criticism for spending on the space program, which intensified when the ISRO lunar probe lost radio contact with the probe after ten months. But Chandrayaan-1 was deemed a major success when it discovered water and a protective magnetic field on the moon.
Of course, a mission to Mars is a whole new beast, and they’ll be up against a lot of rough history when it launches.

Remember Knight Capital Group’s algorithm-driven stock trading glitch from yesterday?
Turned out that 45 minute mistake, the company said in a statement, “has resulted in a realized pre-tax loss of approximately $440 million.”
In other words, about $10 million per minute, which makes it a ridiculously expensive mistake.

A stock-trading algorithm gone awry appears to have thrown American stock markets into chaos on Wednesday, following a surge of volatile trading after the opening bell. Many of the country’s biggest companies were affected, including Bank of America, Alcoa, General Electric, Berkshire Hathaway, Citigroup, and American Airlines.
Financial news sites have pinpointed the problem to Knight Capital Group. The brokerage firm’s algorithm appears to have triggered purchases and sales of millions of shares for 30 minutes.
Algorithmic trading, where stock transactions are mediated by high-speed data connections and software rather than humans, is something that’s been rapidly overtaking the industry in recent years. The infamous “flash crash†of 2010 led to a loss of 573 points on the Dow Jones Industrial Average in five minutes.

The pills, made by Proteus Digital Health, have sand-particle-sized silicon chips with small amounts of magnesium and copper on them. After they’re swallowed, they generate voltage as they make contact with digestive juices. That signals a patch on the person’s skin, which then relays a message to a mobile phone given to a healthcare provider. It’s only been approved for use with placebos right now, but the company is hoping to get it approved for use with other drugs (which would be where it would get the most use).
Even if there’s a slight whiff of dystopia about a pill that tracks your actions, it does help with a major problem. Patients aren’t the best at taking their pills, especially those suffering from chronic illnesses, so it’s one step of many toward a future where they don’t have to.
