How Google Earth Is Changing Science

How Google Earth Is Changing Science (broken link removed) by Manfred Dworschak:

Google Earth wasn’t really intended for scientists….
But now the scientific community is discovering how useful the software is for their own work.

With a single keystroke, biologist Born superimposes colored maps over the Arctic. The maps show him where the ice sheet is getting thinner and the direction in which the pieces of floating ice on which walruses like to catch a ride are drifting. All of the ice data, which comes from satellites and measuring buoys, is available on the Internet. By loading the data into the program, Born can detect how global warming is affecting the migratory behavior of his giant walruses.

The way simple to use tools will be used is hard to predict. By making tools (and ideas – open access research) readily available (and customizable – Google Map API) allows the community to build upon the tool in wonderful and unanticipated ways.

Tools, that may indeed be technically superior, may languish while simple to use, widely available, tools can flourish and create great benefits (from the network effect).

Excellence in K-12 Mathematics and Science Teaching

Going to School with Samuel Wheeler (NSF does not provide a way to link directly so you have to look down the page to find this interview of teacher Samuel Wheeler).

NSF: What is your most successful tool to inspire students to study science?
Wheeler: I craft my science courses in such a way that the students themselves become the investigator and principal learner, and I become a guide or facilitator. If they are allowed to explore the material from their own interests with the proper springboard, then it is easier to inspire them.

Samuel Wheeler received the, Presidential Awardees for Excellence in Mathematics and Science Teaching – USA.

NSF Undergraduate Scholarships in Science, Technology, Engineering, and Math

NSF Undergraduate Scholarships in Science, Technology, Engineering, and Mathematics (S-STEM)

program details from NSF (web site for schools)

This program makes grants to institutions of higher education to support scholarships for academically talented, financially needy students, enabling them to enter the workforce following completion of an associate, baccalaureate, or graduate level degree in science and engineering disciplines. Grantee institutions are responsible for selecting scholarship recipients, reporting demographic information about student scholars, and managing the S-STEM project at the institution.

The program does not make scholarship awards directly to students; students should contact their institution’s Office of Financial Aid for this and other scholarship opportunities.

Thanks to Marisa Dorazio, Edmonds Community College, for mentioning this. Apply for the scholarships available from Edmonds Community College. The deadline to apply is Friday, August 18. The application form has contact information in case you have any questions.

Beyond Genetics in DNA

Scientists Say They’ve Found a Code Beyond Genetics in DNA by Nicholas Wade:

The genetic code specifies all the proteins that a cell makes. The second code, superimposed on the first, sets the placement of the nucleosomes, miniature protein spools around which the DNA is looped. The spools both protect and control access to the DNA itself.
…
Jerry Workman of the Stowers Institute in Kansas City said the detection of the nucleosome code was “a profound insight if true,” because it would explain many aspects of how the DNA is controlled.

A New Ocean?

Secrets of ocean birth laid bare:

Geologists say a crack that opened up last year may eventually reach the Red Sea, isolating much of Ethiopia and Eritrea from the rest of Africa.
…
“We think if these processes continue, a new ocean will eventually form,” he told the BBC News website. “It will connect to the Red Sea and the ocean will flow in.”

When do they expect this? “in about a million years.” Just around the corner geologically speaking, though for me that still seems a long way off 🙂

Primary Science Education in China and the USA

Should the US Take a Page Out of China’s Schoolbook?

China consistently performs well on international benchmarks despite having to serve 20% of the world’s students with only 2% of its educational resources.

Pretty impressive.

But mimicking China’s system is by no means a blanket solution for American education woes.

Mimicking is almost never a successful strategy. What can be successful is learning from what others do well and adopting the good ideas in ways that makes sense in your system.

Robot Learning

This is very cool stuff:

Indeed, as opposed to the work in classical artificial intelligence in which engineers impose pre-defined anthropocentric tasks to robots, the techniques we develop endow the robots with the capacity of deciding by themselves which are the activities that are maximally fitted to their current capabilities. Our developmental robots autonomously and actively choose their learning situations, thus beginning by simple ones and progressively increasing their complexity. No tasks are pre-specified to the robots, which are only provided with an internal abstract reward function. For example, in the case of the Intelligent Adaptive Curiosity which we developped, this internal reward function pushes the robot to search for situations where its learning progress is maximal.

Very interesting article from Sony Computer Science Laboratory Paris (Developmental Robotics): Discovering Communication by Pierre-Yves Oudeyer and Frederic Kaplan, abstract:

Berkeley and MIT courses online

Huge amount of University of California Berkely webcasts of course lectures. Subscribe to RSS feeds and listen to podcasts or listen online.

Courses include: General Biology, Solid State Devices and Introductory Physics. Course websites include handouts for the lectures.

A great open access resource.

I can’t believe I have mentioned MIT open courseware before but a search didn’t find anything. MIT’s effort is an excellent resource, many on science and engineering: Brain and Cognitive Sciences, Materials Science and Engineering, etc..

MIT also includes the excellent: Visualizing Cultures – a gateway to seeing history through images that once had wide circulation among peoples of different times and places by John Dower (author of National Book Award and Pulitzer Prize winning: Embracing Defeat: Japan in the Wake of World War II) and Shigeru Miyagawa.

Science 2.0 – Biology

OpenWetWare (OWW) is an effort to promote the sharing of information, know-how, and wisdom among researchers and groups who are working in biology and biological engineering.

“OWW provides a place for labs, individuals, and groups to organize their own information and collaborate with others easily and efficiently. In the process, we hope that OWW will not only lead to greater collaboration between member groups, but also provide a useful information portal to our colleagues, and ultimately the rest of the world.”
