Episode 9: 31st October - 6 November
NASA in Final Preparations for Nov. 8 Asteroid Flyby NASA scientists will be tracking asteroid 2005 YU55 with antennas of the agency's Deep Space Network at Goldstone, Calif., as the space rock safely flies past Earth slightly closer than the moon's orbit on Nov. 8. Scientists are treating the flyby of the 1,300-foot-wide (400-meter) asteroid as a science target of opportunity – allowing instruments on "spacecraft Earth" to scan it during the close pass. Tracking of the aircraft carrier-sized asteroid will begin at 9:30 a.m. local time (PDT) on Nov. 4, using the massive 70-meter (230-foot) Deep Space Network antenna, and last for about two hours.

The catch – you are limited to 140 characters on Twitter. Oh, yes, also the entry must “explain the origins of the Universe.” Credit: Wikipedia Simple – should be plenty of entries for that! I guess the trick is in the syntax, as well as the science. Answer simple question – win an iPad | Open Parachute
The sun is hot outside, the cicadas are buzzing, the next door neighbour is mowing their lawn, the beginning of summer is here…. You step outside your house into the noise and heat of the day, and…. Mmmm…. that lovely smell of newly cut grass. Its fresh, green and very inviting. But the same cannot be said for the small, generally unseen members of our gardens. While we might love the smell of fresh cut grass; insects and other ground bugs don’t have the same reaction. The Self Preservation of Grass | Digging the Dirt
I’m always looking around for ways to improve my teaching, & my students’ learning. (The two go hand in hand. I might think I’m a good teacher, but unless my classroom practices improve my students’ learning experiences & outcomes, then I’m not. visualising a curriculum | BioBlog

A Laser to Give the Universe a Hernia? Think back to 2008, when the Large Hadron Collider (LHC) was about to be switched on for the first time. Remember all those “micro-black hole,” “spacetime-ripping,” “stranglet-creating” doomsday headlines? TOP 5: Misconceptions About the LHC Although much of the hype was complete nonsense, those pesky physicists are at it again; they want to build a laser so powerful that it will literally rip spacetime apart.

Boeing to Build Commercial Spacecraft at Kennedy, Create 550 Jobs Steven Siceloff, John F. Kennedy Space Center The Boeing Company will set up Orbiter Processing Facility-3 at NASA's Kennedy Space Center in Florida to manufacture and assemble its CST-100 spacecraft for launches to the International Space Station under a newly signed agreement with NASA and Space Florida. And that deal could provide a glimpse of how Kennedy's unique facilities will be used in the future. "It's a clear sign that NASA will continue to be an engine for growth," said Lori Garver, the agency's deputy administrator, in announcing the deal during a ceremony Oct. 31 at OPF-3.

Search for Elusive Higgs Boson Particle on Hold Until 2012 | Large Hadron Collider (LHC) Particle Accelerator | Search for Higgs Boson New Physics One of the world's most elusive particles will stay hidden a while longer, it seems. Scientists at the gigantic Large Hadron Collider (LHC) particle accelerator at the CERN physics lab in Switzerland have wrapped up — at least for 2011 — the kind of experiments that might have shown a glimpse of the long-sought Higgs boson particle. The Higgs boson, which has been theorized but never observed, is thought to give all other particles their mass.
Alternate ending: Living on without telomerase Nov. 4, 2011 — Scientists of the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have discovered an alternative mechanism for the extension of the telomere repeat sequence by DNA repair enzymes. The ends of the chromosomes, the telomeres, are repetitive DNA sequences that shorten every time a cell divides during the process of duplicating its genome. Once the telomeres become very short the cell stops dividing. Thus, telomeres work like a cellular clock that keeps an eye on the number of cell divisions.
The master list of email delivery terminology Scientists from Queensland University of Technology (QUT) have developed a new material for cleaning up contaminated water from radioactive leaks and medical processes. The team mixed titanate nanofiber and nanotubes into a powder that, it says, will clean the radioactive particles in a ton of water with a single gram, provided it’s properly distributed or filtered.
