Use the Force

Behold Project Epoc, a wireless headset developed by Australian start-up Emotiv Systems. The electrodes embedded in the set read your brain waves, figure out what you’re thinking and, yes, allow you to bend objects on the screen to your omnipotent will.
…
Let’s be clear, though: Epoc isn’t anywhere near as easy as picking up a control pad and learning to play a game. The software uses adaptive learning to figure out what your brains’ electrical signals look like when you’re thinking about lifting, pushing, or rotating objects. That takes time (which is why Dave used the headset and not me).

Still, I think I’d be willing to sacrifice an hour of my life for a taste of the Jedi’s power. The effect is amazing, after all – c’mon, this is mind-control people!

Ok, this is not yet available and needs quite a bit more to make consumers demand them – but if it can do what they say that is interesting start. Project Epoc

Your Online Identity

Social Networking Sites: Enter At Your Own Risk by Amina Sonnie, IEE-USA Today’s Engineer:

Your Career Builders profile may be the professional face you wear online, but sites like MySpace or Facebook may be perceived as the “real” you. Many college students and entry-level employees may think that these social networking sites are not part of the adult world and forget that they are being viewed as an adult by their employer. To put a different face on the “real,” the first thing you may want to do is Google yourself. What comes up first?

Try me: John Hunter – usually my homepage or something about the another, John Hunter, the “father of modern surgery”, no relation. I found the above via: Facebook is public not private where John Dupuis added:

As an aside, when I’m on a search committee I always Google at least the short listed candidates and often many of the other applicants as well. I’ve never found anything shocking. On the other hand, I’m always surprised when I can’t find anything about a candidate. How can you be an active professional (or even an aspiring one) in this day and age and leave no impression on the web?

I agree.

As a society, we have a large bias toward punishing acts of commission – versus acts of omission. So the failure to have established a credible online presence is not normally as big a problem as creating one people object to. However, people should not become so fearful of doing something wrong that they fail to take advantage of the opportunity to enhance their career with a positive online presence: Ackoff on errors of omission.

Engineering a Better Blood Alcohol Sensor

Scott McCain - Duke Student

Scott McCain Aims for Better Blood Alcohol Sensor:

If third-year engineering graduate student Scott McCain gets his way, the fight against drunk driving may soon be waged with a new, non-invasive blood alcohol sensor that could make standard blood or breath sample tests obsolete. The St. Louis native’s interdisciplinary research – a combination of engineering, physics and computer science – aims to build a small and inexpensive optical device capable of using harmless light to pass through skin and directly determine blood alcohol concentration.

“The device uses light at wavelengths at which skin essentially becomes transparent,” McCain said. “We shine a laser through tissue where it interacts with blood. By analyzing the scattered light that comes back out, we can determine much about the blood’s chemical content.”
…
Similar devices hold promise for determining other constituents of blood. For example, they could measure cholesterol or blood sugar in a matter of minutes, McCain said. Ultimately, the goal is to have a sensor that could report a medical reading in less than 10 seconds.
…
“We don’t yet know if our blood alcohol sensor will really work,” said McCain. “It wouldn’t be research if we knew what it was all about.”

A Life-changing Gift

A nice human interest story, A life-changing gift:

All children have dreams. Many boys dream of growing up and becoming prime minister, a pilot, a doctor or an astronaut. For young Anusorn Pinsuwan, however, he didn’t dream that much. ”I just wanted to study. Then I could dare to dream of being something else, like an engineer or a teacher. But I didn’t think I could make my dreams come true as I didn’t have the money to study,” said Anusorn, now 25. ”But, at least, we shouldn’t sabotage our own dreams. We should give ourselves a chance.”

One of his dreams has been achieved, thanks to the support of the Bangkok Post readers, through a Bangkok Post Foundation scholarship. After excelling at Rajamangala University of Technology, Tak campus, he secured a place at King Mongkut’s Institute of Technology, North Bangkok, studying civil engineering. He graduated in 2005, and his first job offer from a private construction company followed shortly.

Science and Engineering Internships

Externs.com is another curious cat web site: an internship directory. It is getting late to try and find an internship for the summer but if you are still looking you can find science internships and engineering internships via that site.

The list of companies includes: Google, Intel, NASA, Dell, NIST, Scripps Research Institute, US Navy, National Cancer Institute, Microsoft and the International Crane Foundation. If you have any internship positions you would like included you may suggest an addition.

Engineering Quiet, Efficient Planes

Fly Silent, Fly Cheap by Jeffrey Winters, Mechanical Engineering magazine:

In all, the design changes would amount to a startling reduction in the amount of sound produced on takeoff and landing. The Cambridge-MIT team estimates that a landing SAX-40 would create less than 65 decibels of noise at the perimeter of the airport—about the same level as background noise. Transformed in this way, airplanes would be relatively neutral parts of the urban environment, rather than nuisances.

But there’s a side benefit: fuel efficiency. The same design elements that cut back on noise also reduce fuel consumption. With less energy lost to creating turbulence, more power would be devoted to moving passengers.

NSF Cafe Scientifique: Arlington, Virgina

Cafe Scientifique NSF. Where: The Front Page, 4201 Wilson Blvd, Arlington, Virginia (Ballston Metro stop). 6:30PM-8:00PM presentation, followed by Q&A: The “Shocking” Science Behind Electric Cars:

Science makes many things possible, including alternative fuels and modes of personal transportation… Goldstein and Garlow are the President and VP of the DC area Electric Vehicle Association. They will discuss the science behind electric cars, such as fuel cells and battery technology, and some of the issues surrounding their use and acceptance. And, they will bring actual cars to touch and explore, including the MIT entry into the 1994 Tour de Sol, an electric car that is solar-powered, and an all-electric Toyota RAV4.
…
Cafe Scientifique flourished first in the U.K. as a way for the public and scientists to mingle and discuss science issues in an informal setting. At least 35 cafÃ©s now exist in the U.S.

I hope to make it this month.

European Innovation Scoreboard

European Innovation Scoreboard (pdf)

The US and Japan are still ahead of the EU25 in terms of innovation performance, but the innovation gap between the EU25 and Japan, and in particular with the US is decreasing (see Figure II). The EU25 has improved its relative performance compared to the US in S&E graduates, tertiary education, business R&D, early-stage venture capital, medium-high and high-tech manufacturing employment, EPO patents, USPTO patents and community trademarks. The EU has improved its relative performance compared to Japan mostly in S&E graduates and broadband penetration rate.
…
Sweden, Switzerland, Finland, Denmark, Japan and Germany are the innovation leaders, with SII scores well above that of the EU25 and the other countries…
The US, UK, Iceland, France, Netherlands, Belgium, Austria and Ireland are the innovation followers, with SII scores below those of the innovation leaders but above that of the EU25 and the other countries.

NSF Summer Institute on Nano Mechanics and Materials

NSF Summer Institute on Nano Mechanics and Materials is offering short courses this summer, one at Northwestern and one at UCLA. NSF fellowships are available to professors, high-school science teachers, post-docs and Ph.D. candidates from US universities. The fellowship consists of full tuition plus a travel allowance, if applicable. Apply by April 1, 2007. I really like that the NSF provides funds to help people attend this type of thing.

The objectives of the NSF Summer Institute on Nano Mechanics and Materials are:

* To identify and promote important areas of nanotechnology, and to create new areas o focus which will augment current nanotechnology research and development by universities, industries and government.
* To train future and practicing engineers, scientists and educators in the emerging areas of nanotechnology, nano-mechanics, and nano-materials.
* To exchange new ideas, disseminate knowledge and provide valuable networking opportunities for researchers and leaders in the field.

The short courses offered by the Institute provide fundamentals and recent new developments in selected areas of nanotechnology. The material is presented at a level accessible to BS graduates of science and engineering programs. Emphasis is on techniques and theory recently developed that are not available in texts or standard university courses.
