For decades, “bigger is better” has been the conventional path to efficiency in industries ranging from transportation to power generation. Food once grown on small family plots now comes overwhelmingly from factory farms. Vessels that carried 2,000 tons of cargo have been replaced by modern container ships that routinely move 150,000 tons. But now, new

SENIOR serving officers in any country’s armed forces tend to shun public controversy. But Admiral Jonathan Greenert, America’s chief of naval operations, has stoked it in the latest issue of a specialist journal. His article appeared to question the value of the stealth technologies that underpin the biggest weapons project in history, the vast and

Biological Sciences Assistant Project Scientist Kyung Won Kim (left) and Professor Yishi Jin. Discovery Offers New Genetic Pathway for Injured Nerve Regeneration On the hunt for genes involved in regenerating critical nerve fibers called axons, biologists at the University of California San Diego came away with a surprise: The discovery of a new genetic pathway

DGIST researchers are getting closer to developing a material that delivers a one-two punch: recycling atmospheric carbon dioxide for the production of cleaner hydrocarbon fuels. Copper and platinum nanoparticles added to the surface of a blue titania photocatalyst significantly improve its ability to recycle atmospheric carbon dioxide into hydrocarbon fuels. The modified photocatalyst was developed

Image via Wikipedia HE economic news in California has been pretty bleak lately. Its businesses, small and large, are becalmed by the recession. The state has taken to issuing i.o.u.’s in the wake of political wrangling over how to resolve a $26 billion budget deficit.

Aluminum could give a big boost to capacity and power of lithium-ion batteries. One big problem faced by electrodes in rechargeable batteries, as they go through repeated cycles of charging and discharging, is that they must expand and shrink during each cycle — sometimes doubling in volume, and then shrinking back. This can lead to

Humanity today faces incredible threats and opportunities: climate change, nuclear weapons, biotechnology, nanotechnology, and much, much more. But some people argue that these things are all trumped by one: artificial intelligence (AI). To date, this argument has been confined mainly to science fiction and a small circle of scholars and enthusiasts. Enter documentarian James Barrat, whose
