Wide Angle: Technology to Save the World

May 04, 2009

Scientists are harnessing computing systems such as the Internet and embedded sensing networks to keep tabs on the world. What they learn could help us observe ecologies we've never seen before, identify endangered species and even see health trends that could adversely affect large populations. In this wide angle, we'll take a look at the technologies on mission to save the world.

• Podcast: Vodafone Wireless Innovation Project
  Vodafone operates in 25 countries, some of them developing nations, where things like infectious diseases and sudden natural disasters take heavy tolls. In response, it sponsored the Wireless Innovation Project. One hundred applicants submitted ideas that harnessed new and existing wireless technologies in pursuit of social good. Clark Boyd talks with the top three winners.

• Blog: Will the Internet Say "I Told You So"?
  The Internet is being eyed as a way to warn us about ecological catastrophe. Our current ecological monitoring systems just aren't fast enough -- looking for key words and patterns online from scientists, government officials, and casual observers could be more effective.

  When the next big earthquake strikes Tokyo, an early-warning system could help save lives and property.

• IM Interview: Curing the Mosquito to Stop Malaria
  Malaria is a complex disease that involves the interactions of three organisms: human, parasite, and mosquito. If scientists can interrupt any of these interactions, they could control the disease. Tracy Staedter chats with George Dimopoulos about the methods researchers are developing.

• Blog: Tech for the Developing World, Stat! Malaria
  Dr. Robert Malkin is a professor of bioengineering at Duke University and director for the Engineering World Health program. He recently spoke with me about key problem areas in the developing world and emerging solutions.

  A text messaging-based program, called Mobiles in Malawi, is saving lives by connecting rural communities to hospitals. Kasey-Dee Gardner explain how it works.

• Top 10: Ways Cell Phones Help People Living in Poverty
  Cell phones are becoming ubiquitous, even in underdeveloped countries. This unprecedented penetration by a communications technology is clearly changing the face of the developing world for the better -- in some cases, in ways that not even the most visionary leaders anticipated.

• Top 10: Innovations for Impoverished People
  Two billion people in the world don't get enough to eat, approximately one billion live on less than a dollar a day and every year 1.4 million children die because they lack sanitary conditions and access to clean water. Some humanitarians think these numbers can be lowered with simple technologies. Here are 10 that are making a difference.

Computers Give Makeovers; Rank Prettiness

March 31, 2008

It's a sad day in Selfworthland when we start relying on computers to suggest beauty tips and then hold out for affirmation as another one ranks attractiveness. Ok, it's not that bad. But it could go there.

Two computer graphics researchers from the University of California at San Diego have created a free website called Taaz that allows would-be beauty queens to upload photos and then try out more than 4,000 makeup products. And because everyone is going the way of social networking, once you upload on image and make yourself over, you can share with other Taaz friends, who can give you points for style. Press release here.

And if you can't accept your Taaz points as good enough, you could try to get your hands on the sw that ranks facial attractiveness, being developed by computer scientists at Tel Aviv University. Touted as a "substantial advance in the development of artificial intelligence," the program uses an algorithm to crunch 98 beauty characteristics, such as hair color, skin smoothness, and facial symmetry to rank beauty. The numbers ultimately come from rankings that were initially submitted by humans but the computer was able to learn from those and make its own predictions.

What did the computer find beautiful? Mugs that lacked extreme facial characteristics. Hey Big Nose Horse Face. You may need a computerized makeover.

Circuits Do the Twist

March 28, 2008

There's just one word for circuits that help power laptops, cell phones, computers, and just about every other electronic device: rigid. That feature not only makes computer chips brittle and subject to breakage, but also makes them inflexible, which limits where they can be used.

Now researchers have advanced development of stretchable silicon circuits. The electronics can be pulled, compressed, folded, and deformed without adverse effect on their performance. This could make it possible to use them in nonconventional ways, such as wrapping them around rounded objects. Imagine a robot with electronic skin, for example, or a human prosthetic of the same material, for that matter. There is also opportunity for wearable systems that monitor health conditions or offer therapy, as well as systems that wrap around mechanical parts such as aircraft wings and fuselages to check for structural properties.

The researchers, led by John Rogers of the University of Illinois, report their work in this week's issue of Science.

Lab Laser Fires up Black Hole

February 13, 2008

Typically, black holes are resigned to deep space. But scientists have used laboratory lasers to simulate an event horizon, the point-of-no-return boundary that surrounds the edge of a black hole.

The results could allows physicists to peer into the mouth of the beast, so to speak, and examine what happens to light unable to escape from the hole's great gravitational pull.

Ulf Leonhardt, of the University of St Andrews, UK, and his team performed the experiment by sending a pulse of slow-moving laser light down an optical fiber and then following it up with a faster pulse.

A news story about the research appears in this week's issue of New Scientist. The articles describes what happens:

The first pulse distorts the optical properties of the fibre simply by traveling through it. This distortion forces the speedy probe wave to slow down dramatically when it catches up with the slower pulse and tries to move through it. In fact, the probe wave becomes trapped and can never overtake the pulse’s leading edge, which effectively becomes a black hole event horizon, beyond which light cannot escape.

Leonhardt and his team recently reported their work at the Cosmology Meets Condensed Matter meeting in London.

To learn more, see this week's video on Discovery New's "Why Tell Me Why," which explains why black holes exist.
