Scientists Make A Mini Mona Lisa 30 Microns Wide

Scientists Make A Mini Mona Lisa 30 Microns Wide.jpg

Researchers at the Georgia Institute of Technology have “painted” the Mona Lisa on a substrate surface approximately 30 microns in width – or one-third the width of a human hair. The team’s creation, the “Mini Lisa,” demonstrates a technique that could potentially be used to achieve nanomanufacturing of devices because the team was able to vary the surface concentration of molecules on such short-length scales.

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.jpg

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.
