Protecting half of the planet could directly affect over one billion people

Solar Electricity for over One Billion People and Two Million Jobs by 2020

A planet with two billion cars

Road block: Economists predict that there will be two billion motor vehicles on the roads by 2030, as private vehicle ownership spreads to the developing world.

From the sheer amount of bad news coming through the 24/7 news cycle, one may get the impression that the world is on the road to apocalypse. To counter this impre...

Over one-half billion years of head conservation? Expression of an ems class gene in Hydractinia symbiolongicarpus (Cnidaria: Hydrozoa).

We report the isolation of an empty spiracles class homeodomain-containing gene, Cn-ems, from the hydrozoan Hydractinia symbiolongicarpus, the first gene of this class characterized in a lower metazoan. Cn-ems was found to be expressed in the head of gastrozooids, specifically in endodermal epithelial cells of the taeniolae of the hypostome. Cn-ems is not expressed in gonozooids, which lack tae...

One Billion Transistors, One Uniprocessor, One Chip

A billion transistors on a single chip presents opportunities for new levels of computing capability. Depending on your design point, several distinct implementations are possible. In our view, if the design point is performance , the implementation of choice is a very high-performance uniprocessor on each chip, with chips interconnected to form a shared memory mul-tiprocessor. The basic design...

Big Biking Payoff: Alternative Transportation Could Net Midwest over $8 Billion

Persistent organic pollutants (POPs) are long-lived environmental contaminants that are widely detected in humans. Elevated circulating levels of POPs have been linked to hypertension, obesity, diabetes, meta bolic syndrome, and myocardial infarction in humans. Atherosclerosis, characterized by lipid-rich plaques on the inner wall (intima) of the artery, also can lead to myocardial infarction a...
