Transparent Iron
February 16, 2012 01:08 PM - Editor, ENN

When one thinks of iron one thinks of a dull grey solid. Transparent iron is an odd thought. The effect of electromagnetically induced transparency (EIT) is a known phenomena from laser physics. With intense laser light of a certain wavelength it is possible to make a non-transparent material transparent for light of another wavelength. This effect is generated by a complex interaction of light with the atomic electron shell. At DESY's X-ray source PETRA III, the Helmholtz research team of Röhlsberger managed to prove for the first time that this transparency effect also exists for X-ray light, when the X-rays are directed towards atomic nuclei of the Mössbauer isotope iron-57 (which makes up 2% of naturally occurring iron). The potential real world benefit for this phenomena may be in the a quantum effects computer which would be extremely fast.

Once, men abused slaves. Now we abuse fossil fuels
February 6, 2012 04:51 PM - Andy Gryce, Population Matters

Pointing out the similarities (and differences) between slavery and the use of fossil fuels can help us engage with climate change in a new way, says Jean-François Mouhot, visiting researcher at Georgetown University, USA. In 2005, while teaching history at a French university, I was struck by the general disbelief among students that rational and sensitive human beings could ever hold others in bondage. Slavery was so obviously evil that slave-holders could only have been barbarians. My students could not entertain the idea that some slave-owners could have been genuinely blind to the harm they were doing. At the same time, I was reading a book on climate change which noted how today's machinery — almost exclusively powered by fossil fuels like coal and oil — does the same work that used to be done by slaves and servants. "Energy slaves" now do our laundry, cook our food, transport us, entertain us, and do most of the hard work needed for our survival.

Heat is Power Association Launches

Kelsey (Walker) Southerland, Executive Director, Heat is Power Association
In his recent State of the Union address, President Obama called upon an America built to last, "an economy built on American manufacturing, American energy, skills for American workers, and a renewal of American values." Today, the Heat is Power Association is ready to answer this call in this country and beyond. A coalition focused on the wide-scale development of a robust Waste Heat to Power (WH2P) market re-launched today as the Heat is Power Association to bring together everyone with a stake in clean energy and industry to capture an opportunity we're wasting every day—waste heat. And we're not alone. From the White House to the campaign trail to state houses across the country, almost everyone can agree on two things: that the way to spur the global economy is through manufacturing, and we must shore up clean energy supplies to power and protect cities and towns everywhere. Alongside President Obama's call for a renewed manufacturing sector, he touted the thousands of jobs that have been created at the hands of clean energy investments. By expanding our focus on the output of energy resources — emission-free electricity — we can grow those numbers exponentially.

Roach Wars

I remember the day my roommate spotted the first cockroach in our apartment.
