Items for students and others, interested in learning about science and engineering and the application of science in our lives. We post many of the general interest items here.

Great Moonbuggy Race

Great Moonbuggy Race – Huntsville Center for Technology High School and Pittsburg State University win their divisions.

The two winning teams were among 33 that raced their original moonbuggy designs across a half-mile simulated lunar surface at the U.S. Space & Rocket Center in Huntsville April 7-8.

Sports Engineering

MIT is not the first school to come to mind when discussing athletics. However, the MIT Center for Sports Innovation (CSI) is making news. The CSI mission is to expand the students’ learning experience by involving them in the development of sports technology and products.

One project at the Center is a wind tunnel used for bicycle testing:

The design and construction of the bike test stand was Brian Hoying’s senior thesis project. The data acquisition software upgrade was Mark Cote’s freshman term project. The resulting test system was deemed “the best cycling test system I’ve ever seen” by Phil White, owner of CervÃ©lo Cycles, and sponsor of the CSC professional cycling team.

It is great to see student projects with such success.

Figuring ways to go faster with the flow by Phil McKenna, Boston Globe

Mark Cote, a researcher at the MIT Center for Sports Innovation, has an impressive list of clients — from Tour de France stage winners to some of North America’s leading bicycle manufacturers. Now the wind tunnel specialist plans to use his expertise in fluid dynamics to develop and, he hopes, patent his own advances in aerodynamic cycling gear.

Not bad, considering that Cote, 21, is still an undergraduate.

Google Announces 2006 Anita Borg Scholarship Winners

The Google Anita Borg Memorial Scholarship was established to honor the legacy of Anita Borg and her efforts to encourage women to pursue careers in computer science and technology. The award is a $10,000 scholarship for outstanding female undergraduate and graduate students completing their degrees in computer science or related fields.

Virus-Assembled Batteries

Virus coated polymer dipped in battery material

Virus-Assembled Batteries by Kevin Bullis:

More than half the weight and size of today’s batteries comes from supporting materials that contribute nothing to storing energy. Now researchers have demonstrated that genetically engineered viruses can assemble active battery materials into a compact, regular structure, to make an ultra-thin, transparent battery electrode that stores nearly three times as much energy as those in today’s lithium-ion batteries. It is the first step toward high-capacity, self-assembling batteries.
…
One of the ways they have done this in the past is using a process called “directed evolution.” They combine collections of viruses with millions of random variations in a vial containing a piece of the material they want the virus to bind to. Some of the viruses happen to have proteins that bind to the material. Isolating these viruses is a simple process of washing off the piece of material –only those viruses bound to the material remain. These can then be allowed to reproduce. After a few rounds of binding and washing, only viruses with the highest affinity for the material remain.

NASA Engineering Challenges

NASA has been increasing the use of challenges to encourage innovation along the lines they could use for their future missions. The NASA challenges now 9 open challenges including the: beam power challenge and the astronaut glove challenge.

These centennial challenges provide a small monetary award to encourage solutions to challenges.

By making awards based on actual achievements, instead of proposals, Centennial Challenges seeks novel solutions to NASA’s mission challenges from non-traditional sources of innovation in academia, industry and the public.

Like to Tinker? NASA’s Looking for You by Noah Shachtman

Many of NASA’s contests also center on robotics. The Telerobotic Construction Challenge, scheduled for August 2007, requires a team of machines to assemble items with minimal human supervision. The idea is to let robots, instead of astronauts, build shelters and machinery on the moon and Mars.

Are Antibiotics Killing Us?

Are Antibiotics Killing Us? by Jessica Snyder Sachs:

To counteract these killers, some physicians have turned to lengthy or lifelong courses of antibiotics. At the same time, other researchers are counterintuitively finding that bacteria we think are bad for us also ward off other diseases and keep us healthy. Using antibiotics to tamper with this complicated and little-understood population could irrevocably alter the microbial ecology in an individual and accelerate the spread of drug-resistant genes to the public at large.

Articles on the overuse of antibiotics.

Salyers says her research shows that decades of antibiotic use have bred a frightening

degree of drug resistance into our intestinal flora. The resistance is harmless as long as the bacteria remain confined to their normal habitat. But it can prove deadly when those bacteria contaminate an open wound or cause an infection after surgery.

Organs Engineered in a Lab

Straight Out of Science Fiction: Organs Engineered in a Lab:

Several years after receiving new bladders engineered entirely in a laboratory, seven young patients are all still healthy.

It marks the first long-term success of total-organ tissue regeneration, an area of medicine that until now was more the stuff of science fiction than clinical reality.

Science Education in the 21st Century

Science Education in the 21st Century: Using the Tools of Science to Teach Science podcast by Dr. Carl Wieman, recipient of the Nobel Prize in Physics in 2001. Also received the first NSF Distinguished teaching Scholars award (NSF’s “highest honor for excellence in both teaching and research”) and the National Professor Of The Year (CASE and Carnegie Foundation).

Dr. Carl Wieman, recipient of the Nobel Prize in Physics in 2001, discusses the failures of traditional educational practices, even as used by “very good” teachers, and the successes of some new practices and technology that characterize this more effective approach. Research on how people learn science is now revealing how many teachers badly misinterpret what students are thinking and learning from traditional science classes and exams.

However, research is also providing insights on how to do much better. The combination of this research with modern information technology is setting the stage for a new more effective approach to science education based on using the tools of science. This can provide a relevant and effective science education to all students.

Robot Dreams

RAYERD-X robot

Video podcast of amazing robot:

One of the most surprising robots that appeared at the 9th Robo-One competition held here in Tokyo on March 18-19th, 2006, was RAYERED-X developed by Asurada. Its unique design allows it to reconfigure and transform itself into some amazing shapes. At first it looks like a short tower, then becomes a carousel, then a walking spider, then into a tall biped battle robot.

All sorts of robot news via the Robot Dreams blog, including RAYERD-X – The Magical Robot:

The robot really surprised the crowds, but may have puzzled the panel of judges to some extent. It’s hard to make a direct comparison between RAYERD-X and the more conventional robot designs. Nevertheless, it did capture the 24th position during the initial Demonstration phase of the Robo-One 9 competition and was awarded the Sunrise Special Prize.

2006 FIRST Robotics Competition Regional Events

2006 FIRST Robotics Competition Regional Events in Philadelphia, Denver, Houston and more 30 March – 1 April.

Competition events are, in the words of our teams, “full of passion, excitement, joy, and sorrow…the thrill of success and the agony of defeat.” The FIRST Robotics Competition has grown to 33 regional events and the Championship.

Boston FIRST Robotics Event by Computer Science Teacher

I was amazed at how much interest in engineering and science FIRST generated. A lot of students were inspired to look at area of education that they had never ever thought about before.

One of the things I noticed this year was that the number of girls involved in FIRST continues to climb. At the Boston event three of the 44 teams were all girls. All of the teams seemed to have significant numbers of girls. People at FIRST say that there are upwards of 30% girls in the program. That could be better of course but it is growing.
…
I highly recommend you drop in on one. FIRST has to be seen to really be understood.
