ALMA telescope begins operations
National Radio Astronomy Observatory    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The NRAO is proud to announce that ALMA officially began Early Science Operations on schedule on Sept. 30. An NRAO press release provides additional information on this historic ALMA achievement, including images and HD video. The first astronomical images from ALMA are also online. NSBP member Kartik Sheth, his NRAO colleague Adam Leroy and Brad Whitmore of STScI in this webcast discuss ALMA early science, and explain how ALMA will contribute to our understanding of the universe.

At the NSBP annual conference that took place the week of Sept. 26, Dr. Sheth, ALMA's commissioning and verification liaison, was able to brief South Africa's S&T minister on the complementariness of ALMA to KAT-7, MeerKAT and SKA, and invited more African participation in ALMA under open skies.

Congress poised to cut NSF, NIST and support for HBCUs/MSIs
Various Sources    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Federal funds for minority-serving colleges and universities are on the chopping block for next year as the House of Representatives is proposing deep cuts or outright elimination of many of these programs for the government's 2012 fiscal year. So far the Senate is holding opposition to these cuts. Meanwhile the Senate is proposing to cut funding for the National Science Foundation by 2.4 percent, and the National Institute of Science and Technology by 9 percent. Physicists are being encouraged to write to their Senators urging them to oppose the cuts to to NSF and NIST. More

Physics Nobel Prize will attract controversy
IOP Blog    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Assigning credit for a scientific discovery is never easy, especially when two rival, interacting teams of scientists are involved. That is exactly the problem that the Nobel committee must have grappled with before awarding this year's physics prize to Saul Perlmutter, Adam Riess and Brian Schmidt. More



Physics looms large in this year's chemistry prize
Physics World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Tenfold symmetry had never been observed before and was actually thought to be forbidden. So Daniel Shechtman's 1984 discovery generated huge excitement, confusion and significant opposition. After being rejected by the Journal of Applied Physics, Shechtman's original paper was ultimately published in Physical Review Letters and has since become one of the most-cited research articles in the scientific literature.

Einstein's blunder is somebody else's Nobel Prize
Time    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Einstein called his 1916 introduction of the cosmological constant his biggest blunder. When Einstein developed the equations of general relativity back in 1916, he applied them to the universe as a whole. To his consternation, they predicted that if the universe wasn't expanding, it should be collapsing. It seemed obvious that it wasn't expanding — but since it wasn't collapsing either, something must be propping it up. Einstein called the something the cosmological constant and added it to his theory with some distaste, because the work had been so mathematically beautiful without it. More



Does the Nobel Committee's limit on the number of persons cited in prizes ignore the way science discoveries are made today?
PhysOrg.com    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The Nobel Committee has a tradition that a prize cannot be shared between more than three individuals. But these days breakthroughs commonly come from collective labor involving dozens, sometimes hundreds, of minds working across multiple sub-disciplines in lavishly funded organizations. The 2011 physics prize went to three astronomers involved in two big teams who discovered that the expansion of the universe was accelerating, not slowing as thought. The first publication announcing the discovery of a real material crystal with tenfold symmetry had three co-authors. More

First X-ray laser produces most coherent X-ray radiation ever
PhysOrg.com    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Experiments show that the world's first X-ray laser, the Linac Coherent Light Source, produces the most coherent (laser-like) X-rays ever measured. Single-shot measurements were performed at 780 eV X-ray photon energy using apertures containing double pinholes in "diffract-and-destroy" mode. Tests have shown that 78 percent of the total power is contained in the dominant mode. This all means that researchers using such an X-ray laser will soon be able to more precisely understand the atomic structure of materials. More

Comet with Earth-like ocean water discovered
University of Michigan    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Using the Heterodyne Instrument for the Infrared on the Herschel Space Observatory, astronomers have found that the ice on a Jupiter-family comet called Hartley 2 has the same chemical composition as Earth's oceans. Both have similar deuterium/hydrogen isotope ratios. Published in Nature, the result substantially expands the possible sources of water in the Earth oceans, and is consistent with the emerging picture of a complex dynamical evolution of the early solar system.

The search for a more perfect kilogram
Wired    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Of the seven fundamental metric units — the kilogram, meter, second, ampere, kelvin, mole and candela — only the kilogram is still dependent on a physical object. The object that serves as the prime standard for the kilogram, the Le Grand K. is held in Paris. It is periodically compared to sister objects also in Paris and to 48 national standards held in various places around the world. Over the last several decades Le Grand K has been losing mass relative to its sister objects and the national standards, creating a real dilemma in the field of metrology. Two different approaches to linking the kilogram to a fundamental constant are in the works, and a final decision of which standard to use will be taken up at the 24th Convocation of the General Conference on Weights and Measures, Oct. 17-21, in Paris.

Flying telescope makes an out-of-this-world find
NPR    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Astronomers are lining up to use a powerful new NASA telescope called SOFIA. The telescope has unique capabilities for studying things like how stars form and what's in the atmospheres of planets. But unlike most of the space agency's telescopes, SOFIA isn't in space — it flies around mounted in a Boeing 747 jet with a large door cut on the side so the telescope can see out. More

At one time or another nearly every graduate student and new faculty member wonders about his or her competence. This is a common fear often referred to as the impostor syndrome. The impostor syndrome runs rampant in academia — and women are especially prone to it. How do you get over the impostor syndrome? Easier said than done. More
