Watch astronaut Chris Hadfield's zero-gravity workout

If you think your workout is reaching a plateau, don't complain to the men and women in space. They have to constantly work out to stave off the loss of muscle tissue.

People living in zero gravity can lose up to 5 percent muscle mass a week. Yikes! That's why working out isn't just something astronauts do because they had a double cheeseburger with onion rings for lunch. Curious about what a space workout looks like? … Read more

More Americans opting to cut cord on traditional TV

While the vast majority of U.S. residents own televisions and watch them regularly, more and more people are opting to toss their cable plans and use other devices for entertainment.

A new report by Nielsen finds that those people who have elected to go "Zero TV" have more than doubled since 2007. Currently, more than 5 million people don't have broadcast television in their home, while in 2007 just 2 million didn't.

Despite these numbers sounding big, cord-cutters are still just 5 percent of the U.S. population. And, as Nielsen wrote in a blog … Read more

Microsoft to patch IE zero-day flaw today

Microsoft will fix a zero-day hole in IE today almost a week after this month's regular Patch Tuesday updates.

Discovered late last month, the vulnerability could allow attackers to gain control of a Windows computer running one of the older versions of IE by directing users to malicious Web sites. In response, Microsoft had suggested several workarounds and even offered a "one-click fix" designed to mitigate the problem, but those were considered temporary solutions.

Today's update will fully resolve the issue, according to Microsoft. Scheduled for rollout at 10 a.m. PT, the fix will be … Read more

Java flaw draws Web attacks, reports say

Security researchers have spotted a new vulnerability in the widely used Java software that could give attackers access to your computer.

The US-CERT group today issued an alert saying that Java 7 Update 10 and earlier versions of the software contain an unspecified vulnerability that can allow a remote, unauthenticated attacker to execute arbitrary code. The attack can be induced if someone visits a Web site that's been set up with malicious code to take advantage of the hole.

This weak spot is already being attacked "in the wild" -- that is, it's a real-world threat … Read more

Microsoft's next Patch Tuesday won't resolve IE zero-day flaw

Microsoft's regular Patch Tuesday rolls around next week. But one flaw that won't be fixed in the mix is the latest zero-day exploit in Internet Explorer.

In its advisory, the company noted that IE 9 and 10 are unaffected by the vulnerability and suggested a variety of workarounds to those running the older browser versions.

On Monday, the company issued a temporary fix that prevents the flaw from being … Read more
