11:47 AM | Landing on a Comet...
So, what will we find?Ice, minerals are sure bets. Hopefully the harpoons they've engineered hold on whatever qualifies as a "surface" on a comet. The fun of science is the unknown; that's the adventure!The ancient Greek on the Rosetta Stone told archaeologists that it was inscribed by priests honoring the king of Egypt, Ptolemy V, in the second century B.C. More startlingly, the Greek passage announced that the three scripts were all of identical meaning. The artifact thus held the key to […]

11:27 AM | First steps: A journey into physics
Being a young student, my attention is quite easily taken away. Luckily enough, my mind gets captivated by the evolutionary world of physics more often than it does by video games and sports. Every time I venture into this strange, developing world I discover that I now know a little less than when I started […] The post First steps: A journey into physics appeared first on physicsfocus.org.

8:10 AM | Nanoimprint lithography for the fabrication of efficient low band gap polymer solar cells
In recent years, polymer solar cells have drawn considerable research interest due to their attractive features including flexibility, semi-transparency, and manufacturability using cost-effective continuous printing processes. However, one challenge limiting their commercialization is the relatively low power conversion efficiency when compared to inorganic solar cells. New work shows that low bandgap polymer solar cells with high efficiency of 5.5% can be fabricated using nanoimprint […]

5:20 AM | A Lighthouse at the Heart of the Milky Way: Hunting Cosmic Neutrinos
Andrea Peterson We are pleased to welcome Andrea Peterson as a guest blogger today. Andrea is a co-author of a paper reporting that the supermassive black hole at the center of our galaxy may be a source of highly energetic neutrinos, as explained in our latest press release. Andrea recently completed her Ph.D. at the University of Wisconsin-Madison, where she studied particle phenomenology. She is now a postdoctoral researcher at Carleton University in Ottawa, Ontario. She was born and raised […]

5:10 AM | NASA X-ray Telescopes Find Black Hole May Be a Neutrino Factory
The supermassive black hole at the center of the Milky Way, seen in this image from NASA's Chandra X-ray Observatory, may be producing mysterious particles called neutrinos, as described in our latest press release. Neutrinos are tiny particles that have virtually no mass and carry no electric charge. Unlike light or charged particles, neutrinos can emerge from deep within their sources and travel across the Universe without being absorbed by intervening matter or, in the case of charged […]

5:00 AM | Investigating the Earth’s Inner Workings
A team is using Oak Ridge National Laboratory’s (ORNL’s) Titan supercomputer to reveal the Earth’s inner workings via adjoint tomography simulations, or monitoring the interaction of a forward wavefield, in which the waves travel from the source to the receivers, and an “adjoint” wavefield in which the waves travel inversely from the receivers to the source.

11:20 PM | How to Watch the Comet Landing!
On the 12th of November the European Space Agency will make the first ever attempt to land a space probe on a comet. If all goes to plan, the Rosetta orbiter will deploy the Philae lander into a seven-hour drift onto the surface of Comet 67P  Churyumov–Gerasimenko.  I'll do a full blog after the event, but here's some hopefully useful bits and pieces to follow the high point of the Rosetta mission: The first port of call is the ESA Livestream, where all the major events will be […]
