NSBP member Calvin Howell leads project applying nuclear physics to safe ports
Maritime Executive    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Two teams of physicists at the Triangle Universities Nuclear Laboratory in North Carolina have identified new "fingerprints" of nuclear materials, such as uranium and plutonium that can be used in new cargo scanners to accurately and efficiently identify suspicious materials. Using the world's most intense and tunable source of polarized gamma rays, one team is exploiting characteristic ejections of neutrons from targets upon irradiation, while another team is exploring the energy pattern and distribution of the gamma rays that fluoresce after the photon-matter interaction.

Joint Conference of the National Society of Black Physicists and the National Society of Hispanic Physicists

We are pleased to announce the 2011 Joint Annual Conference of NSBP and NSHP will be held Sept. 21-24 at the Renaissance Hotel in Austin, Texas. With more than 600 participants, this meeting is the largest gathering of African-American and Hispanic physicists in the world. This is an exceptionally good meeting for students to attend. Students can present posters or oral presentations, attend professional development and scientific sessions, and network with fellow students and faculty. The conference includes one of the largest and most successful physics career fairs in the U.S. The sponsors include the National Science Foundation, the University of Texas at Austin and the Southeastern University Research Association.

Physicists explain the long, useful lifetime of carbon-14
TRIUMF    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In a tour de force of computational nuclear physics, a team of American and Canadian physicists have demonstrated in a recent paper in Physical Review Letters that three-nucleon forces cancel much of the pairwise forces in the carbon-14 nucleus, and that this extends the half-life of carbon-14 by many orders of magnitude. The long, slow decay of carbon-14 allows archaeologists to accurately date the relics of history back to 60,000 years. More

The shape of the electron is perfectly spherical and its dipole is zero — as best as we can tell
Nature News    Share    Share on FacebookTwitterShare on LinkedinE-mail
The standard model of particle physics predicts that the electron is slightly aspherical and has an infinitesimal dipole moment. Extensions to the theory and improved experimental sensitivities recently reported in Nature News have brought the predicted electron dipole moment and the ability to measure it closer together. Still the electron is observed to be nearly perfectly spherical with a zero dipole. The results raise profound questions about anti-matter and time-reversal symmetry. More

Zero field NMR spectroscopy
Physics World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Conventional NMR requires the sample to be placed in a very high magnetic field, which needs large and expensive superconducting magnets. But an innovative technique employing polarization of proton spin isomers and an optical atomic magnetometer has made zero-field NMR spectroscopy on a complex hydrocarbon molecule accessible. More

Rotation rate reveals a star's age
Physics World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Using NASA's Kepler space telescope, a team at Harvard-Smithsonian Center for Astrophysics has measured the rotation rates for stars in a 1 billion-year-old cluster called NGC 6811. Kepler is designed to detect small changes in brightness and therefore able to measure the spin of a variety of stars. A star's rotation rate can be correlated to its age, and its color can be related to its mass. So observing a star's color and its periodic changes, it has been possible to find a correlation between rotation rate, mass and age. More

Egyptian legislative group approves 'science city'    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Approving an idea proposed by Nobel Laureate Ahmed Zewail 10 years ago, Egypt will create a "science city" that will include a university and an institute for science and technology as part of its post-revolution efforts to promote higher education and innovation in the country and the Arab and African regions. Using science diplomacy for putting an end to Egypt's troubled relations with Sub-Saharan Africa, the new government also announced that it would provide scholarships to Ugandan students to study in Egyptian universities.

Short-term exploitation of African land and water may lead to long-term problems
Physics Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Countries such as China, India and Saudi Arabia have begun to lease well-watered land in Africa to grow food crops. Doing so is cheaper and easier than maintaining and improving the water resources back home. Two papers published in Geophysics Research Letters warn that leasing of African water sources could make the continent more vulnerable to market forces and the effects of climate change. More

Consortium including Puerto Rican university takes over stewardship of Arecibo
Nature News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
SRI International, a nonprofit research institute based in Menlo Park, Calif; the Universities Space Research Association in Washington, D.C.; and the Metropolitan University in Puerto Rico will be taking over the management of Arecibo Observatory from Cornell University. The consortium will sponsor faculty positions at the University of Puerto Rico and will create a commission that will study other ways in which local institutions can get more involved with the facility. Arecibo is currently, and is likely to remain, the most sensitive instrument of its kind for the foreseeable future. A 500-meter radio dish under construction in Guizhou, China, will not reach the higher frequencies that Arecibo can detect. More

Physicist Bill Foster will seek return to Congress in 2012
Los Angeles Times    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The three-member Congressional Physicist Caucus was reduced to one after the last congressional election. Vern Ehlers retired, and Bill Foster was defeated. But Foster has just announced that he will seek to return to Congress in 2012. Foster is a former researcher at Fermi National Lab and a Fellow of the American Physical Society. He served in Congress for three years after first winning a special election to replace former Speaker Dennis Hastert, and then winning the regular election in 2008. More

England's Royal Society seeks better public engagement as climate scientists are being targeted by campaigns of requests designed to slow down their research
The Guardian    Share    Share on FacebookTwitterShare on LinkedinE-mail
Nobel laureate Sir Paul Nurse, president of the Royal Society, reports that some climate scientists were being targeted by organized campaigns of requests for data and other research materials, aimed at intimidating scientists and slowing down research. Meanwhile in the United States, the University of Virginia will turn over records related to climate research, and in a separate case, Virginia's attorney general is pursuing legal action aimed at geophysicist Michael Mann. Responding to incidents like these, and to more benign public curiosity about science, the Royal Society has launched a major study into how scientists' work can be made more open and better used to inform policy in society.

SETI scours Earth for cash; donations sought to restart deep space search
Redding Record Searchlight    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The search for intelligent life among the cosmos has turned into a quest for cash on Earth. Since mid-April, the Allen Telescope Array, a collection of radio dishes about 75 miles east of Redding, Calif., has been in hibernation after the state and federal government steeply cut funding. To bring the array back online, the Search for Extraterrestrial Intelligence Institute is trying to find $2.5 million a year in support. More

SETI initiates effort to gamify search for extraterrestrial life
Mashable    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The Search for Extra-Terrestrial Intelligence project has launched a contest with Gamify to get the general public involved in the search for alien signals. Sifting through waterfall plots (the method SETI’s software uses to visually represent signal data for humans) is dull and tedious work on its own. So to get people involved, SETI has seeking to add game play mechanics to make searching for hidden signals more fun and engaging. More
