This week we are presented with a collection of celestial alignments that are quite visible in an urban setting.

Climate change may supersize sweet potatoes
RISING levels of carbon dioxide in the atmosphere may
have a silver lining: doubling the size of the sweet potato, the fifth
most important food crop in the developing world.
Most studies of the effects of higher atmospheric CO2
on crops have shown rising yields of rice,

Big Idea Bring Back the "Cold Fusion" Dream
In 1989 Stanley Pons and Martin Fleischmann
made a sensational claim that would have changed the world—had it been
true. They said they had achieved nuclear fusion at room temperature
using a simple tabletop device, thus creating a revolutionary clean
energy source they called “cold fusion.”

Solar system’s birth record revised
Some 4.567 billion years ago, our
solar system’s planets spawned from an expansive disc of gas and dust
rotating around the sun. While similar processes are witnessed in
younger solar systems throughout the Milky Way, the formative stages of
our own solar system were believed to have taken twice as long to occur.
Now, new research lead by the Centre for Star and Planet Formation at
the Natural History Museum of Denmark, University of Copenhagen,
suggests otherwise.

Polystyrene atoms could surpass the real deal
SOMETIMES a copy can surpass the original. Imitation
atoms made of microscopic polystyrene spheres have bonded with each
other using the same three-dimensional geometries found in real
molecules. These surrogate atoms could one day be used to build novel
materials such as semiconductors that carry light rather than
electricity.
