H1N1 thrives in respiratory system

Blood tests by top flu researcher also show that many survivors of the 1918 pandemic seem to have immunity to swine flu, but not to the seasonal flu that hits every year

FILM-RWANDA: Genocidaires Face Off With Their Victims

NEW YORK, Jun 4 (IPS) – In 1994, hundreds of thousands of Tutsi were slaughtered by their Hutu neighbours, friends, and family members across Rwanda. Nine years later the killers came home from prison to live side by side again with their victims.

Fashion’s Issey Miyake Haunted by Hiroshima

Issey Miyake’s clothes are famous for color and exuberance, but the Japanese designer has a tragic past: He survived the atomic bomb dropped on Hiroshima. Miyake has declined to talk about the blast, “preferring to think of things that can be created, not destroyed,” he writes in the New York Times . But President Obama’s [...]

Remnant of a Supernova

Vital clues about the devastating ends to the lives of massive stars can be found by studying the aftermath of their explosions. In its more than twelve years of science operations, NASA's Chandra X-ray Observatory has studied many of these supernova remnants sprinkled across the galaxy. The latest example of this important investigation is Chandra's new image of the supernova remnant known as G350.1+0.3. This stellar debris field is located some 14,700 light years from the Earth toward the center of the Milky Way. Evidence from Chandra and from ESA's XMM-Newton telescope suggest that a compact object within G350.1+0.3 may be the dense core of the star that exploded. The position of this likely neutron star, seen by the arrow pointing to "neutron star" in the inset image, is well away from the center of the X-ray emission. If the supernova explosion occurred near the center of the X-ray emission then the neutron star must have received a powerful kick in the supernova explosion. Data suggest this supernova remnant, as it appears in the image, is 600 and 1,200 years old. If the estimated location of the explosion is correct, this means the neutron star has been moving at a speed of at least 3 million miles per hour since the explosion. Another intriguing aspect of G350.1+0.3 is its unusual shape. Many supernova remnants are nearly circular, but G350.1+0.3 is strikingly asymmetrical as seen in the Chandra data in this image (gold). Infrared data from NASA's Spitzer Space Telescope (light blue) also trace the morphology found by Chandra. Astronomers think that this bizarre shape is due to stellar debris field expanding into a nearby cloud of cold molecular gas. The age of 600-1,200 years puts the explosion that created G350.1+0.3 in the same time frame as other famous supernovas that formed the Crab and SN 1006 supernova remnants. However, it is unlikely that anyone on Earth would have seen the explosion because of the obscuring gas and dust that lies along our line of sight to the remnant. These results appeared in the April 10, 2011 issue of The Astrophysical Journal. Image Credits: X-ray: NASA/CXC/SAO/I. Lovchinsky et al; IR: NASA/JPL-Caltech
