An entrepreneur says he's got a plan to curb urban blight in parts of Detroit. He's buying up acre after acre of abandoned lots and planting thousands of trees. But where backers of the plan see a visionary proposal, critics see a land grab.

Entrepreneur and Detroiter John Hantz, owner of Hantz Farms and the tree-planting effort called Hantz Woodlands, wants to plant at least 15,000 trees on about 140 acres. Hantz promises to clear out all the trash and keep the grass cut, things the city cannot afford to do now.

Future Fibers May Be Spun From Slime

The hagfish or "slime eel" shoots out slime containing silk-like fibers of remarkable strength. Douglas Fudge, a biologist at the University of Guelph, says it could be a good substitute for today's synthetic fibers--it's 10 times stronger than nylon, for example--and bacteria can be trained to make it.

Debunking Doomsday And Exploring Maya Science

Originally published on Fri December 21, 2012 1:08 pm

The ancient Maya had many scientific accomplishments: they tracked the Moon and the planets, knew a solar year was 365 days, and even invented the concept of zero. As for the 2012 apocalypse? It's simply a misinterpretation of the Maya calendar, say archaeologists Marcello Canuto and William Saturno.

Reporting in Science Translational Medicine, researchers write that neural stem cell implants were able to slow the onset of amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, in mice. Study author Evan Snyder discusses the stem cells' protective effect, and why human trials may not be far behind.
