Millions of people across the world live or depend on deltas for their livelihoods.

Formed at the lowest part of a river where its water flow slows and spreads into the sea, deltas are sediment-rich, biodiverse areas, a valuable source of seafood, fertile ground for agriculture, and host to ports important for transportation.

At least half of the deltas around the world are so-called “wave dominated deltas” – open to the sea and under the impact of wave erosion. And many more deltas will come under wave dominance as dammed rivers carry less and less sediment. In a warming climate, sea levels are rising and storms are increasing in frequency and severity, posing threats to these deltas and the people and habitats dependent on them. (more…)

Mr. Fusion Helps Students Build a Nuclear Reactor

*Microsoft employee Carl Greninger helped a team of young students build a working nuclear reactor in his garage. He hopes the project can inspire a passion for physics in students around the country.*

REDMOND, Wash. – Sometimes you have to smash a few atoms to excite people about science.

So says Carl Greninger, a program manager in Microsoft IT Operations by day and full-fledged physics fanatic by night. That’s why he decided to help some young students get hands-on experience with something they couldn’t find in their classrooms: a working thermonuclear reactor.

For the past year, a group of local students – some as young as 13 years old – have met at Greninger’s garage every Friday night to build a type of fusion reactor known as a Farnsworth–Hirsch Fusor. Dubbed IEC-9000, their machine has been fusing atoms and producing neutrons since May. It cost about as much as a high-end SUV, weighs 1,400 pounds, and generates temperatures hotter than the surface of the sun. (more…)

Japan Worst-case Scenario Unlikely to Cause Catastrophic Radiation Release

ANN ARBOR, Mich.— While exposed spent fuel rods at the failing nuclear reactors in Japan pose new threats, the worst-case scenario would still be unlikely to expose the public to catastrophic amounts of radiation, says a University of Michigan nuclear engineering professor who is an expert on this particular kind of reactor.

“For the public, I don’t believe it would be much higher than two additional chest x-rays,” said John Lee, a professor in the Department of Nuclear Engineering and Radiological Sciences, citing the results of the Three Mile Island accident. (more…)
