Stem Cells Used To Grow a New Tooth Inside a Mouse's Mouth

By Stuart Fox Posted on 8.4.2009 8 Comments
Just the sound of a dentist's drill is enough to send most people into a panic. Add to that the awful inconvenience of walking around for a day with half your face numb, and it's easy to see why getting a cavity filled or a tooth replaced is one of life's most annoying chores. Fortunately, some new research may make the common drill-and-fill a thing of the past.

TruFocals Use Liquid Lens for Adjustable-Focus Eyeglasses

By Stuart Fox Posted on 8.4.2009 9 Comments
In 1764, a cartoon showed Benjamin Franklin wearing the first pair of bifocals, and not a lot has changes since then. About 100 years after that, the first pair of adjustable focus glasses was patented in the United States, but it used different fixed-focus lenses. Now, 245 year after Franklin and 143 years after the first adjustable glasses patent, someone has actually developed adjustable lenses that work.

Imagine an automatic shift from near to far with a sensor that can tell when a person squints. No manual switch, just do what comes naturally when your vision is impaired. Just throwin that out there.

Mind-Reading Tech May Not Be Far Off

By Brooke Borel Posted on 6.12.2009 14 Comments
Neuroscientists are already able to read some basic thoughts, like whether an individual test subject is looking at a picture of a cat or an image with a specific left or right orientation. They can even read pictures that you're simply imagining in your mind's eye. Even leaders in the field are shocked by how far we've come in our ability to peer into people's minds. Will brain scans of the future be able to tell if a person is lying or telling the truth?

Mind reading technology and all of a sudden we're all pedophiles. Come on, you know you looked at a teenage girl today.

Playing Movies

By Scott Steinberg Posted on 4.17.2009 3 Comments
According to conventional wisdom, most video games inspired by popular film licenses make Gigli look like Citizen Kane. See: 1982's E.T. the Extra-Terrestrial, which almost single-handedly sunk Atari; 1995's Street Fighter: The Movie, starring a digitized Jean-Claude Van Damme; and 2006's Jaws Unleashed, wherein you play the shark, natch. But as a recent spate of current and upcoming Hollywood adaptations aims to prove, it's not all stale popcorn and watered-down soda for today's couch potato.

Chief among them is X-men Origins:Wolverine. Early reviews are touting it as a possible game-of-the-year contender.

Pointing the Way to Success

By Catherine Schwanke Posted on 1.16.2009 9 Comments
What does it take to be a successful financial trader? Education, experience, and, according to new research at the University of Cambridge, a long ring finger.

If your ring finger is longer than your index finger you have aids.

Could Tapping the Planet for Geothermal Energy Cool the Earth’s Core?

By Stuart Fox Posted on 9.9.2008 7 Comments
Global warming, holes in the ozone layer, and lush golf courses in the desert all reveal mankind’s ability to mess with the planet. But the Earth’s core, protected by an outer core consisting of some 1,000 miles of 8,000˚F liquid metal, appears safe from our meddling.

In Defense of the LHC

By Posted on 3.18.2009 23 Comments
Today’s most ambitious scientific instruments are modern-day cathedrals in their size and complexity, if not in their purpose—these are, after all, structures built to shatter worldviews, not to reinforce them. And the grandest of all, pictured on these pages and fired into action today, will take us on a journey to one of the least-accessible places imaginable: the realm of quantum particles, less than a billionth the size of a single atom.

6 billion really ain't a whole lot of money when you're talking about the collaboration of this many countries. B. Gates could write the check himself. Man to think what we will see in the next 50 years if technology advances even close to what the last 50 years gave us. Wow.

Readers Wonder: How Will It All End?

By PopSci Staff Posted on 9.10.2008 21 Comments
Nobody's implying that it's right around the corner, but an old question is on a lot of people's minds these days -- especially you readers. How will the world end? Wikipedia has a nice list of some possible scenarios. What's your favorite? Discuss in the comments.

"All living things were born to die..." If anyone can tell me what game that line is from you (like I) have played way too many games. Back on subject, I believe in the literal resurrection of the body and spirit. The earth (like the body) was created, will die and then be resurrected. There is one glory of the sun, another glory of the moon, and another glory of the stars. So also is the resurrection of the dead, it is sown in corruption, it is raised in incorruption. And no I'm not a JW. The zombie comment was funny.

Ms. Scientist

By Holly Otterbein Posted on 9.11.2008 7 Comments
In 2005, the then-president of Harvard University said that men are better at math and science than women. (President Lawrence Summers' exact words were a bit more roundabout. While theorizing why women are underrepresented in those fields, he said "there is a different availability of aptitude at the high end.") Turns out Summers's attitude may be to blame, according to a new study from vocational psychologists at the University of Wisconsin-Madison.

I agree with meltykiss. I also like your comment tidus. I'm a dude and I've always been better at math than other subjects; it's the one truth in the universe.

The Modern Twist on an Ancient Shoe

By Posted on 5.14.2008 6 Comments
Imagine a shoe so uncomfortable you have to hammer the insole and smash it inside a door to make it tolerable. Now imagine tossing the same $70 shoe in the trash because it shredded into pieces after just 45 minutes. Welcome to the world of ballet.
