to see what happened, reports New Scientist. While some of the treated spiders produced webs of a lower grade than usual, the team found that some produced silk that was an amazing 3.5 times tougher and stronger than the best naturally produced silk, that of the giant riverine orb spider. In fact it was the nanotubes that provided the highest performing materials. Its not clear what happened to silk to provide the extra strength. One hypothesis is that the graphene and nanotubes coated the outside of the strands; another is that the carbon materials leached into the spider and became incorporated into the silk they produced. Regardless of how it works, its not without risk for the spiders: four of them died after being sprayed, before they could even spin any silk. So while the technique of imbuing spiders with strength-giving materials is oddly promising, it requires some work before it can be used reliably to create new forms of super silk.

The radar imagery revealed that 1998 QE2 is a binary asteroid. In the near-Earth population, about 16 percent of asteroids that are about 655 feet 200 meters or larger are binary or triple systems. Radar images suggest that the main body, or primary, is approximately 1.7 miles 2.7 kilometers in diameter and has a rotation period of less than four hours. Also revealed in the radar imagery of 1998 QE2 are several dark surface features that suggest large concavities. The preliminary estimate for the size of the asteroid satellite, or moon, is approximately 2,000 feet 600 meters wide. The radar collage covers a little b stanley uk it more than two hours. The radar observations were led by scientist Marina Brozovic of NASA Jet Propulsion Laboratory, Pasadena, Calif. stanley termohrnek The closest approach of the asteroid occurs on May 31 at 1:59 p.m. Pacific 4:59 p.m. Eastern / 20:59 UTC , when the asteroid will get no closer than about 3.6 million miles 5.8 million kilometers , or about 15 times the distance between Earth and the moon. This is the closest stanley deutschland approach the asteroid will make to Earth for at least the next two centuries. Asteroid 1998 QE2 was discovered on Aug. 19, 1998, by the Massachusetts Institute of Technology Lincoln Near Earth Asteroid Research LINEAR program near Socorro, N.M.
