Webcasts for the News Media

NSF produces background briefings that bring together leading scientists and engineers and the news media in advance of the announcement of major news discoveries or breakthroughs. These events, originally webcast live, are now available for on-demand viewing.

Sleep Apnea October 22, 2009 Sleep apnea is a serious disorder that causes a person to momentarily stop breathing while he or she sleeps. In this media briefing, Ioannis Pavlidis, Eckhard-Pfeiffer Professor of Computer Science at the University of Houston, and Jayasimha N. Murthy, M.D., assistant professor of medicine from the Division of Pulmonary Critical Care Sleep Medicine at the University of Texas Health Science Center at Houston, describe a new method they created called thermal infrared imaging (TIRI) to diagnose sleep apnea. TIRI is less invasive and more comfortable than traditional sleep studies that use a variety of leads and probes on the patient's upper and lower face to gather data.

This is one of the findings Samuel C. Silverstein of Columbia University and his colleagues describe in the Oct. 16 issue of Science magazine. In this background briefing, Silverstein discusses the benefits of having science teachers take part in research experiences.

The latest research on Oregon's oceanic "dead zones" and how climate change may be promoting them is the topic of this webcast featuring Jack Barth of Oregon State University.

LIGO: Uncovering Properties of the Early Universe August 19, 2009 The LIGO Scientific Collaboration's first major paper on the early universe was published in the Aug. 20 issue of the journal Nature. In a background briefing, Vuk Mandic, one of the paper's lead authors, describes the new findings. Mandic is assistant professor at the University of Minnesota and LIGO's Stochastic Working Group cochair.

The images helped astronomers gain a better understanding of Saturn's largest moon, and they reported their findings in the Aug. 13, 2009, issue of Nature. In a background breifing, astronomers Henry Roe of Lowell Observatory and Mike Brown of Caltech discussed observations of storm clouds in Titan's tropics.

Guests: Robert Shiller, Yale University economist; Colin Camerer, Caltech economist; Nancy Lutz, program director for economics at NSF View webcast (Time: 35:37)
In Defiance of Earthquakes: Standing Strong--2009 NEESWood Capstone Test July 14, 2009 Only hours after a full-scale earthquake test of six-story building, researchers discussed the test and NSF's multi-year NEESWood project. Guests: John van de Lindt, civil engineer at Colorado State University and principal investigator for NEESWood; Hidemaru Shimizu, researcher with E-Defense, Japan National Research Institute for Earth Science and Disaster Prevention; Hiroshi Isoda, Associate Professor, Dept. of Architecture & Civil Engineering Shinshu University, Nagano, Japan; Joy Pauschke, director of NSF's George E. Brown, Jr. Network for Earthquake Engineering Simulation research program; and Edward Matsuyama from American Forest & Paper Association, Tokyo Office.
