Scientists Help Explain Scarcity of Anti-Matter
A collaboration with major participation by physicists at the University of Wisconsin-Madison has made a precise measurement of elusive, nearly massless particles, and obtained a crucial hint as to why the universe is dominated by matter, not by its close relative, anti-matter.

Dispersant Used to Clean Up 2010 BP Oil Spill Made Oil 52-times More Toxic
If the 4.9 million barrels of oil that spilled into the Gulf of Mexico during the 2010 Deep Water Horizon spill was a ecological disaster, the two million gallons of dispersant used to clean it up apparently made it even worse – 52-times more toxic. That’s according to new research from the Georgia Institute of Technology and Universidad Autonoma de Aguascalientes (UAA), Mexico.

Oldest Spear Points Date to 500,000 Years
A collaborative study involving researchers at Arizona State University, the University of Toronto, and the University of Cape Town found that human ancestors were making stone-tipped weapons 500,000 years ago at the South African archaeological site of Kathu Pan 1 – 200,000 years earlier than previously thought. This study, “Evidence for Early Hafted Hunting Technology,” is published in the Nov. 16 issue of the journal Science.

Mosquitoes Fly in Rain Thanks to Low Mass
Even rain can’t deter mosquitoes. The blood-sucking insect can fly in a downpour because of its strong exoskeletons and low mass render it impervious to falling drops. Georgia Tech researchers determined this using high-speed videography.

NASA’s Hubble Shows Milky Way is Destined for Head-on Collision with Andromeda Galaxy
NASA astronomers announced they can now predict with certainty the next major cosmic event to affect our galaxy, Sun, and solar system: the titanic collision of our Milky Way galaxy with the neighboring Andromeda galaxy. The Milky Way is destined to get a major makeover during the encounter, which is predicted to happen four billion years from now. It’s likely the Sun will be flung into a new region of our galaxy, but our Earth and solar system are in no danger of being destroyed.
