5 Myths About the Bird Flu

With all of the information floating around regarding the bird flu epidemic it can be hard to discern what you should really be concerned about and what is nothing more than a rumor. Here are five myths regarding the bird flu that aren’t as factual as they first may seem:

  1. Any ingestion of infected poultry can be deadly: If the poultry is cooked thoroughly enough, even if it was infected prior to cooking, then it can be safe to eat. The virus cannot live through the extreme heat required for cooking, and will die off. Just make sure to cook your poultry thoroughly before consuming it to err on the side of safety. (more…)

Supernovae of the Same Brightness, Cut From Vastly Different Cosmic Cloth

Berkeley Lab researchers make historic observation of rare Type 1a Supernova

Exploding stars called Type 1a supernova are ideal for measuring cosmic distance because they are bright enough to spot across the Universe and have relatively the same luminosity everywhere. Although astronomers have many theories about the kinds of star systems involved in these explosions (or progenitor systems), no one has ever directly observed one—until now.

In the August 24 issue of Science, the multi-institutional Palomar Transient Factory (PTF) team presents the first-ever direct observations of a Type 1a supernova progenitor system. Astronomers have collected evidence indicating that the progenitor system of a Type 1a supernova, called PTF 11kx, contains a red giant star. They also show that the system previously underwent at least one much smaller nova eruption before it ended its life in a destructive supernova. The system is located 600 million light years away in the constellation Lynx. (more…)
