Facebook Porn spam attack : How to protect yourself .

Many Facebook users have been inundated with pornographic spam in their newsfeeds as part of a malware campaign targeting the social network. The company told the BBC it has identified the culprit and vulnerability that was exploited, but is asking users to stay vigilant.
Facebook says it has quarantined the malicious accounts and pages behind the attack, but it also offered some simple tips to help users safeguard themselves in the future. Facebook says:

• Don't ever copy and paste code into your browser's address bar unless you're confident the source is legit.
• Make sure your browser is up to date.
• Report anything weird that you see on Facebook using the "report" links throughout the social network.

If you suspect that malware has already gotten a hold of your Facebook account, or if you're seeing unwanted spam, there are three simple steps to attempt to make your account secure again:

•  Change your password. This can be done by visiting your account settings. Be sure to use a strong password with a mix of numbers, symbols, capital and lowercase letters and no dictionary words if possible.
• While you're in your settings, remove any unwanted Facebook apps. This could be the culprit, or the malware could have installed an app without your knowledge.
• Run a virus and malware scan on your entire system.

There are also plenty of third-party products designed specifically to ensure secure time-wasting on Facebook and other social networks. One such offering is BitDefender's SafeGo, which PCWorld's Tony Bradley recently profiled. The SafeGo Facebook App protects against malware, spam and scams. Other products like Defensio provide similar services, with more robust, paid versions available for businesses.
Finally, as always, a little bit of common sense can go a long way online. If something that pops up on your Wall, News Feed or in a message seems suspicious or too good to be true, it probably is. Hit "report" to be safe, or just ignore it and get back to perusing photos of your friends' cats.

Female Orgasm video :

You may know what it feels like to have an orgasm -- but do you know what it looks like? Now, thanks to a team of researchers at Rutgers University, you can see the big "O" in all its colorful glory.
Nan Wise, a 54-year-old PhD student, sex therapist and associate on the research project, agreed to be the guinea pig. She was hooked up to a functional magnetic resonance imaging (fMRI) scanner and stimulated herself while the machine took "snapshots" of her brain every two seconds, across 80 different regions, The Guardian reported. Professor Barry Komisaruk and his team then spliced these snapshots together into an animated film. The movie is the first of its kind.
And Wise isn't the only one to have participated in this project. Another female subject, Kayt Sukel, who also happens to be a science and travel writer, blogged about the experience, discussing the difficulty inherent in having an orgasm while "bolted" to a scanner:

It's not the most romantic spot one might engage in self-loving. In fact, if you've ever spent time in an MRI scanner, it may seem nearly impossible.

Turns out -- for both Wise and Sukel -- the task at hand wasn't impossible at all, and they got to have some fun, all in the name of science.
Watching the video, it's hard not to be visually stimulated by the colors alone. (It's really only a matter of time before someone on YouTube decides to post it with Katy Perry's "Firework" playing in the background.) The color scale, which ranges from dark red to light yellow, represents the amount of oxygen that is being utilized in that section of the brain. As the orgasm reaches its climax, the image lights up.
Komisaruk recently presented his research at the Society for Neuroscience in Washington, DC, although it hasn't been published in a peer-reviewed journal. He hopes that his work will not only allow scientists to understand why some men and women have trouble achieving orgasm, but also understand our body's reaction to pleasure as a whole.
"We're using orgasm as a way of producing pleasure. If we can learn how to activate the pleasure regions of the brain then that could have wider applications," he told The Guardian.                                                                                                          courtesy : TEch crunch
