Bacteria Sprout Conducting Nanowires

Bacteria made to sprout conducting nanowires by Mason Inman

Bacteria that use sugars and sewage as fuel are being investigated as a pollution-free source of electricity. They feed by plucking electrons from atoms in their fuel and dumping them onto the oxygen or metal atoms in the mixture. The transfer of the electrons creates a current, and connecting the bacteria to an electrode in a microbial fuel cell will generate electricity, although not necessarily very efficiently.

Genetically Engineered Machines Competition

Princeton Center for Innovation in Engineering Education post on Genetic Machines Competition.

Find up to date information on the International Genetically Engineered Machine (iGEM) competition:

We believe in the possibility of engineered biological systems, but the only way to test such an engineering hypothesis is to try it practically. The iGEM competition facilitates this by asking students to design and build genetic machines. This generates practical data on the feasibility of engineering biology, and also on best practices. It also provides a powerful educational experience for the students working to overcome the many technical challenges.

This seems like an effort that is properly focused and is applying sensible management and technology to achieve the goals. A very nice things to find.

Meerkats Teach Their Young

School is in for meerkat youngsters (broken link – poor usability):

Researchers from the University of Cambridge in England observed meerkats gradually introducing cubs to prey, showing them how to handle captured insects and even removing the stingers from scorpions before giving them to youngsters.

“Although there are anecdotal reports of teaching in species from chimpanzees to killer whales, until this year solid evidence was really lacking,” said Alex Thornton, co-author of the report appearing in Friday’s issue of the journal Science.
…
Animals teaching their young is probably more common than it appears, Hopp said, but “a clear demonstration, and particularly in a wild population, is the uncommon part.”

“Thus, I think this paper is important, as it makes a clear and unambiguous case for the teaching behavior,” he said.

Google Jobs in Michigan

Google brings in new jobs and hope (Update: Detroit Free Press removed the page so I removed the link – The NY Times has learned how to use the web so you can view their article – news on the Office location) to Ann Arbor, Michigan. Google will open a new research and support center in the University of Michigan home town. It is not a coincidence that Larry Page, of Google’s co-founders graduated from Michigan’s Engineering school. Google would not locate this facility in Ann Arbor only for that reason but his familiarity with the area and a desire to take advantage of the University of Michigan played a role, I believe. This is one more example, for how good schools aid economic development.

Listen to Page’s address at the 2005 commencement for the Michigan College of Engineering.

Safe Water Through Play

Play Pumps

It’s a simple idea. As children spin on a merry-go-round, water pumps from below the ground. It is stored in a tank just a few feet away, making a safe, plentiful supply of water available in the community.

Nearly 700 PlayPumps have been installed in South Africa, providing safe water to a million people living in rural communities. Thousands more PlayPumps will be installed throughout Sub-Saharan Africa, bringing the many benefits of ready access to clean drinking water to millions of underserved people.

Women for Science

A new report, Women for Science, is available from the InterAcademy Council:

Realizing that the low representation of women in science and engineering is a major hindrance to global capacity building in science and technology, the IAC formed an Advisory Panel on Women for science with the mandate to review previous studies, provide examples of effective projects already implemented, and issue a set of actionable recommendations addressed particularly to the world’s science and engineering academies.

The report is a comprehensive report. The report includes a large list of online resources.

The InterAcademy Council:

In May 2000 all of the world’s science academies created the IAC to mobilize the best scientists and engineers worldwide to provide high quality advice to international bodies – such as the United Nations and the World Bank – as well as to other institutions.

In a world where science and technology are fundamental to many critical issues – ranging from climate change and genetically modified organisms to the crucial challenge of achieving sustainability – making wise policy decisions has become increasingly dependent on good scientific advice.

New Engineering School for England

Plans were announced to create a new kind of school, funded equally by Inventor James Dyson and the English Government. In the words of James Dyson, (Dyson school ‘to boost engineers’):

“Our choice now is either to see Britain’s jobs of tomorrow vanish to Mumbai or Shanghai or to educate the next generation in the skills of invention and business-building.”

The Dyson School of Innovation and Design will open in Bath in 2008.

The 14 to 16-year-olds at the school, due to open in 2008, would attend one day a week while those aged 16 to 18 would attend full-time.

Bye Bye Bees

Photo of a bee

The Vanishing by Sharon Levy:

One-third of the food we eat comes from crops that need animal pollinators, a role often filled by bees but sometimes by butterflies, beetles, birds, or bats. Bee-pollinated foods include squash, tomatoes, peppers, apples, and pears. Unfortunately, the honeybees surrounding me are members of a threatened tribe, whose loss would have a dire effect on farmers, not to mention everyone who eats fruits and vegetables.

This problem has been increasing in recent years.

Fees for renting beehives shot up from about $48 to as much as $140 per colony, a previously unheard-of amount. Beekeepers traveled from as far away as Florida and North Carolina to service California’s almond groves. For the first time in 50 years, U.S. borders were opened to honeybees from New Zealand and Australia. The fate of a $1.2 billion crop — more than half of all almond production worldwide — rested on the slender back of the embattled honeybee.

Natural systems seem so powerful that it hardly seems possible that running low on bees is really a concern. But more and more such stories (fish stocks being wiped out…) are being told. This is one of many reasons we need more scientists to study these areas and keep society informed. Enjoy reading this article it is a great example of science, scientific study, communicating scientific knowledge and the impact on society.
