Jan Scheuermann is paralyzed from the neck down, but with the help of a robotic arm controlled by her brain, she’s now able to pour herself a glass of water to drink.
Lancet Medical Journal ran a study using brain implants to control the robotic arm. Two sensors were placed in the motor cortex of her brain. Pulses of electricity inside her brain are translated into commands for the robot arm, which includes a bending elbow and wrist. In about two weeks, Scheuermann perfected the use of her new robot limb.
Scheuermann has progressively lost control over her body since she was diagnosed with spinocerebellar degeneration 13 years ago.

A little over a year ago, 38-year-old entrepreneur Liang Liwan wasn’t making smartphones at all. This year, he expects to build 10 million of them.
Liang’s company, Xunrui Communications, buys smartphone components and then feeds them to several small factories around Shenzhen, in southern China. There, deft-fingered workers assemble the parts into basic smartphones that retail for as little as $65.
Manufacturers built about 700 million smartphones last year. But the market has taken on a barbell shape. On one side are familiar names like Apple and Samsung, selling pricey phones for $300 to $600; on the other, several hundred lesser-known Chinese brands supplied by a thousand or more small factories MORE

CAPTCHAs – the questions that a website asks you to answer to prove if you’re a human being or not – come in many shapes and forms.

Although they most commonly ask you to decipher some words hidden in a distorted graphic, there are more elaborate versions which can ask you tosolve some complicated mathematical calculation or ask you to add toppings to a pizza in an attempt to stop automated bots leaving spammy messages.
As a keen chess player, I was interested to see this CAPTCHA being used on an online chess forum:

Okay, so it’s not much of a challenge if you’re a chess player, but it also clearly locks out any users who do not know how to play chess. (For those of you can’t see the checkmate, the answer is upside-down at the bottom of this article – and make sure to realise that Black is playing from the bottom)
But most importantly, if a CAPTCHA system like this were to become widely-used, how tricky would it be for an automated bot to solve the puzzle?MORE

Google has launched a page and a set of tutorials aimed for webmasters whose site was hacked.
Specifically, Google explains webmasters how to deal with Google’s search warning that a site is dangerous, which usually appears if a hacker has infected the site with harmful code.
“Every day, cybercriminals compromise thousands of websites. Hacks are often invisible to users, yet remain harmful to anyone viewing the page — including the site owner,” claims Google on the site titled “Webmasters help for hacked sites.“
Google starts with a video tutorial (above) which explains the basics of how and why sites get hacked, and then goes into more advanced territory with info on how to quarantine a site, identify its vulnerabilities and clean it up from harmful code.
How do you like Google’s latest initiative? Do you think the material is too advanced or perhaps too simple for the average webmaster? Share your thoughts in the comments.
