Organised nanowires
Finding a way to arrange nanowires on a surface will be crucial to their development as useful materials for future molecular electronics and other nanoscale devices. Now, an Israeli team has demonstrated that single-walled carbon nanotube patterns can be produced using atomic steps on such a surface as a template. They have also devised a new technique, "asymmetric double-exposure back-reflection XRD", to help them determine the surface characteristics. Folate Mystery Finally Solved
Researchers have stumbled on the identity of an enzyme that had been a mystery for more than 30 years. They discovered the missing part of the pathway in how bacteria make the B vitamin folate. Hormone May Be New Drug Target For Preventing Lymphedema, Tumor Spread
A hormone secreted by cells throughout the body and known to play a role in cardiovascular disease and other cell functions is also critical for proper formation of the lymphatic system in mice, according to new research. U.S. Seminaries Under Scrutiny
Radio program transcript from October 2005 about how "America's 229 Catholic seminaries ... are currently getting the once-over from a team of inspectors sent by Rome in what some commentators are describing as a witch-hunt for homosexuals and liberals."Also includes a copy of the "Instrumentum Laboris,"the "list of questions that are being put to every seminarian and every seminary professor,"and links to related information.

What are the cancer drugs of tomorrow and how will they be developed? New targets, such as cell signaling receptors found on cancer tumors, provide tantalizing targets for engineered antibodies and small inhibitory molecules. New therapeutic technologies, such as virus-based therapy against cancers metastasized to nerve cells and a unique two-headed antibody that attaches killer T cells to tumor cells, offer promising methods for controlling disease. NIST Photon Detectors Have Record Efficiency
Sensors that detect and count single photons, the smallest quantities of light, with 88 percent efficiency have been demonstrated by NIST physicists. This record efficiency is an important step toward making reliable single photon detectors for use in practical quantum cryptography systems, the most secure method known for ensuring the privacy of a communications channel. We the People: Asians in the United States
"This report provides a portrait of the Asian population in the United States and discusses the eleven largest detailed Asian groups at the national level, for example: Asian Indian, Cambodian, and Japanese. It is part of the Census 2000 Special Reports series that presents several demographic, social, and economic characteristics collected from Census 2000."Opens directly into a PDF document.

Results from the first long-term study of online videogame playing may be surprising. Contrary to popular opinion and most previous research, the new study found that players' "robust exposure"to a highly violent online game did not cause any substantial real-world aggression. Asian Pacific Americans in Prime Time: Lights, Camera and Little Actio
A study commissioned "to look beyond the raw numbers analyzed and graded in the annual report card [from the Asian Pacific American Media Coalition (APAMC)] and evaluate the type, quality, and complexity of characters portrayed by APIA [Asian Pacific Islander American] actors, as well as APIA actors of mixed ethnicities."It "systematically investigates the portrayal of APIAs on prime time television."From the National Asian Pacific American Legal Consortium (NAPALC).

Seismic sensors developed to track enemy troop movements during the Vietnam war could help ecologists monitor and conserve elephant populations, according to new research published in the British Ecological Society's Journal of Applied Ecology. Dr Jason Wood and colleagues from Stanford University recorded vibrations caused by animal footfalls using a geophone buried near a path. Researchers were able to estimate the number of elephants passing the sensor by the size and frequency of their footfalls.
