Comment Where From? (Score 1) 303

So, the main use of carbon tet was manufacturing the CFC's. this is replacing a chlorine with a fluorine. Done in a manufacturing facility. So, if this is due to it still being used for that purpose, you'd be able to look at the presence of the products. If plants have leaky manufacturing processes, you should see the carbon tet as well as the CFC's.

If I were to guess, it's degassing from old landfills.

Chemically it's not going to happen. Carbon tet is fluorinated to make the CFC's. The CFC's, in use are largely unreactive. We need to recharge due to leaks, not due to decompostion. In the atmosphere, the CFC's aren't going to have a ready source for the chlorine to somehow react back to carbon tet.

Submission + - 1 Old Car Battery Can Help Power 30 Homes (inhabitat.com)

Taffykay writes: Science recently scored a simultaneous victory over pollution for both recycling and renewable energy! A team of researchers at MIT has come up with plan to turn old car batteries into durable solar panels. According to Phys.org, the system proposed by a group of MIT professors and published in the journal Energy and Environmental Science uses a fairly new solar cell technology that includes a compound called perovskite, which is nearly on par with traditional silicon-based cells but takes significantly less material to manufacture.

Submission + - How to read a microbiome study like a scientist.

bmahersciwriter writes: Scientific reports have increasingly linked the bacteria in your gut to health and maladies, often making wild-sounding claims. Did you hear about the mice who were given fecal transplants from skinny humans and totally got skinny! Well, some of the more gut-busting results might not be as solid as they seem. Epidemiologist Bill Hanage offers five critical questions to ask when confronted by the latest microbiome research.

Submission + - As Ebola death toll rises, scientists work on nanotech cure

rlinke writes: Scientists at Northeastern University are using nanotechnology to find an effective treatment for the Ebola virus, which has killed more than 1,200 people and sickened even more.

What makes finding a vaccine or cure such a formidable job is that the virus mutates so quickly. How do you pin down and treat something that is continually changing?

Thomas Webster, professor and chairman of bioengineering and chemical engineering at Northeastern, may have an answer to that — nanotechnology.

Submission + - VertiKUL Drone "Delivers" on Both Hovering and Forward Flight (gizmag.com)

Zothecula writes: When something is sent to you by airmail, it travels in a fast and relatively fuel-efficient fixed-wing aircraft, not a fuel-guzzling helicopter. Nonetheless, when we hear about the possibility of drones being used to deliver items within cities, multirotor-style aircraft are almost always what's proposed – while they're good at maneuvering in urban spaces, they're essentially just little unmanned helicopters. With that in mind, a group of three engineering students from Belgium's KU Leuven (Katholieke Universiteit Leuven) have created a prototype delivery drone known as VertiKUL, which combines the best features of both types of aircraft.

Submission + - Recycled Car Batteries Transformed into Low-Cost Solar Panels

rofkool writes: MIT researcher have developed a method of transforming old lead-acid car batteries into long-lasting, low-cost solar panels.

It is estimated that a single battery could be used to produce enough solar cells to power up to 30 homes.

The discovery addresses two key problems: Firstly the problem of disposing of lead-acid batteries in an environmentally-responsible way, and secondly the difficulty of producing raw lead ore for use in solar cells.

Angela Belcher, W.M. Keck Professor of Energy at MIT and co-author of the study, said: "Once the battery technology evolves, over 200 million lead-acid batteries will potentially be retired in the United States, and that could cause a lot of environmental issues."

Comment So why bother with Brand Recognition (Score 1) 653

Fluke is a manufacturer of higher quality testing equipment, and has put in a lot of effort on brand recognition. It is not by accident that these units match. Now it may be that Sparkfun simply purchased a bunch of cheap Chinese units who had copied the trademarked systems, but it's not Fluke who is at fault here nor should be villanized.

Comment Can't Hire for Lack of Experrience (Score 1) 491

As an employer of "STEM" individuals, I would disagree on the surplus. Now, the area is fairly specialized as an environmental testing lab, and I wonder if that is part of the issue. For our entry level positions, I expect to need to do considerable training, but if I need an individual with prior experience, it is highly rare for me to receive resumes from more than 1 - 2 individuals that actually have the experience necessary. As a $4M company with a staff of about 15 chemists (as in small to very small business) we are often looking nationally to fill experienced positions. If I had need for a larger labor pool as most of the discussion is really about, does that drive the need for a international labor pool?

So, the question that strikes me, is it that the field has so many very narrow specialties, that the university fundamentally cannot put together the program? Does a company want to drive labor costs down? I do not believe that question needs to be answered. But my perspective, the larger impact is not having qualified staff than the salary.

Finally, and I suspect I am the minority here (at /.) when STEM is discussed, it needs to be remembered that it extends well beyond the computer, and programming disciplines.
