Wind-Powered Water Heater

University Students Build Wind-Powered Water Heater by Gregg Kleiner:

A team of engineering students from Oregon State University, inspired by a late professor’s rudimentary sketches, has designed a working prototype of a hot water heating system powered solely by the wind.

The students believe the technology, which uses magnets, a copper plate and plenty of ingenuity, has the potential to birth a new company and ultimately make an impact on the way the world heats water, especially in developing countries.
…
The prototype was the team’s senior design project, a year-long, hands-on engineering course at OSU that all senior engineering students must participate in, choosing an idea or basic design and developing it to the prototype stage. Despite having no funding, the students say the concept has now been proven to work, and several team members considered spinning off a nonprofit company that would bring the technology to developing countries.

35 Dissertation Awards at $21,000 for one year
20 Postdoctoral Awards at $40,000 for one year

Eligible fields include: Anthropology, archaeology, astronomy, chemistry, computer science, earth sciences, economics, engineering, geography, life sciences, linguistics, mathematics, physics, science and psychology. Apply by November 16th.

Nanoscientists Create Biological Switch

Nanoscientists Create Biological Switch From Spinach Molecule:

The scientists used a scanning tunneling microscope to image chlorophyll-a and then injected it with a single electron to manipulate the molecule into four positions, ranging from straight to curved, at varying speeds. Though the Ohio University team and others have created two-step molecule switches using scanning tunneling microscope manipulation in the past, the new experiment yields a more complex multi-step switch on the largest organic molecule to date.

The work has immediate implications for basic science research, as the configuration of molecules and proteins impacts biological functions. The study also suggests a novel route for creating nanoscale logic circuits or mechanical switches for future medical, computer technology or green energy applications, said Hla, an associate professor of physics.

Work for Stephen Hawking

There is an opportunity to work as the Graduate Assistant to Stephen Hawking, author of A Brief History of Time and much more.

The role of ‘Graduate Assistant to Professor Hawking’ is funded as a research post at the University of Cambridge. Normally it is under a 12 month contract, although sometimes the contract is extended to up to 2 years.

The post is available to recent graduates holding a Maths, Physics or Computer Science degree and a full driving licence. Responsibilities include:

Most Dinosaurs Remain Undiscovered

Dinosaurs remain to be discovered (bozos broke link so I deleted it – poor usability)

Peter Dodson of the University of Pennsylvania and Steve Wang of Swarthmore College estimate that 71 percent of all dinosaur genera — groups of dinosaur species — have yet to be discovered.

“It’s a safe bet that a child born today could expect a very fruitful career in dinosaur paleontology,” Dodson said in a statement.
…
The estimates are based on the rates of discovery — about 10 to 20 annually — and the recent increase in finds of fossils in China, Mongolia and South America.

Vast Majority of Dinosaurs Still to Be Found, Scientists Say, National Geographic:

The pair predicts that scientists will eventually discover 1,844 dinosaur genera in total—at least 1,300 more than the 527 recognized today from remains other than isolated teeth.

What’s more, the duo believes that 75 percent of these dinos will be discovered within the next 60 to 100 years and 90 percent within 100 to 140 years, based on an analysis of historical discovery patterns.

Open Course Ware from Japan

Soccer Robots from Osaka University

A number of Japanese Universities are creating open courseware, in cooperation with MIT’s OpenCourseWare initiative (which has spawned the OCW Consortium).

Osaka University OpenCourseWare offers courses in English including: Theory in Materials Science | Fluid-Solid Multiphase Flow

Kyoto University OpenCourseWare aims to:

share information in consideration of the fact that sixty percent of visitors to MIT’s OCW project come from Asia. We will make active use of Japanese in building OpenCourseWare, to recruit talented students from all over Asia as well as to promote the Kyoto University education, with Kyoto’s culture and traditions, to the world at large.

Many of the courses are available in Japanese, some are available in English, including: Applied Pharmacology

Tokyo Tech OpenCourseWare courses include: Advanced Signal Processing – Guided Wave Circuit Theory and Mixed Signal systems and Integrated Circuits.

The Nagoya University OpenCourseWare brings free courseware to the Internet. Currently several courses are available in English including, Basics of Bioagricultural Sciences. They aim to post 25 courses initially.

Great Nanotechnology Overview

Reporting Risk Assessment of Nanotechnology: A reporter’s guide to sources and research issues (pdf) by Trudy E. Bell:

The article discusses how reporters should investigate the risks with nanotechnology, and in doing so provides a good introduction to concepts in nanotechnology:

If engineered nanomaterials have physical properties different from their bulk counterparts, might they also pose new risks to human health in their manufacture, use, and disposal?

As yet, no one knows. Current data basically suggest “it depends.” But researchers both in government and private
industry are keen to find out.

The potential for nanotechnology is amazing but as we have said before the risks presented by nanotechnology also need careful study.

At the nanoscale, fundamental mechanical, electronic, optical, chemical, biological, and other properties may differ significantly from properties of micrometer-sized particles or bulk materials.

One reason is surface area. Surface area counts because most chemical reactions involving solids happen at the surfaces, where chemical bonds are incomplete. The surface area of a cubic centimeter of a solid material is 6 square centimeters—about the same as one side of half a stick of gum. But the surface area of a cubic centimeter of 1-nm particles in an ultrafine powder is 6,000 square meters—literally a third larger than a football field.

Engineering Student Contest Winners Design Artificial Limb

St. Joseph's College of Engineering students

St. Joseph’s engineering college students win design contest, India:

Three students of St. Joseph’s College of Engineering received a cash award of Rs.50,000 for their prototype of an artificial limb, presented in the `National Level Engineering Students Design Contest’.

The contest, organised by the Product Development and Management Association (PDMA), was aimed at encouraging engineering students to design innovative products.

Organising secretary K. Chandrasekaran said the event was held to address the gap between education and industry, promoting design education and take students to the logical end of working prototypes.

Oliver Sacks podcast

Oliver Sacks is a neurologist and author of interesting and entertaining books including: The Man Who Mistook His Wife For A Hat: And Other Clinical Tales. He is most known for explaining the remarkable case histories of extreme brain trauma, and how those instances allow us to learn about the brain.

Listen to webcast of his interview on NPR’s Science Friday. More blog posts on science and engineering podcasts

Engineered Immune Cells Shrink Tumors

Tumors Shrunk by Engineered Immune Cells, Scientists Say by Stefan Lovgren, on an extermintal treatment with 17 patients so far:

“This is the first example of an effective gene therapy that works in cancer patients,” said Steven Rosenberg, chief of surgery at the National Cancer Institute in Bethesda, Maryland, and leader of the research team.

The therapy has so far been applied only to melanoma patients. But the researchers are optimistic that their treatment can be used for many other types of cancer.

The team has already engineered similar immune cells for more common tumors, such as breast, lung, and liver cancers.
…
His team focused on T (thymus) cells, a type of specialized immune cell that can learn to recognize and attack specific “foreign” objects, such as the cancer cells that make up tumors.

In the new study, researchers created tumor-fighting cells by harvesting normal T cells from melanoma patients and genetically engineering these cells to carry receptor proteins on their surfaces that recognize cancer markers.
