Travel up and down California farm country, the Central Valley, and you hardly hear people lamenting the lack of rain or how dry this past winter was. What you hear, from the agriculture industry and many local and national politicians, are sentiments like those expressed by Rep. Devin Nunes:

"Well, what I always like to say is that this is a man-made drought created by government," the Central Valley Republican says.

Scientists, Fishing Fleet Team Up To Save Cod — By Listening

In the ocean off of Massachusetts, an unlikely alliance of scientists and fishermen is on a quest. They're looking for mating codfish. The goal is not only to revive a depleted fish population but to save an endangered fishing community as well.

Cod were once so plentiful in New England waters that people used to say you could almost walk across their backs. Cod fueled a huge fishing industry. But now they're scarce, mostly from overfishing.

Instead Of Replacing Missing Body Parts, Moon Jellies Recycle

Moon jellies have an unusual self-repair strategy, scientists have learned. If one of these young jellies loses some limbs, it simply rearranges what's left until its body is once again symmetrical.

"We were not expecting to see that," says Michael Abrams, a graduate student in biology at the California Institute of Technology.

All creatures have tricks to heal themselves. If you get a cut, your skin will form a scar. And some sea creatures, like starfish and sea cucumbers, can regenerate lost body parts.

I confess: As a Ph.D.-carrying mother of two and student of human behavior, I couldn't resist reading Primates of Park Avenue, the provocative memoir about motherhood on New York City's Upper East Side, released this month.

When we asked adults who play sports which one they play the most, golf topped the list. That's right: Our poll finds that a day on the links beat out soccer, softball and tennis.

My first reaction was: Whaaat? Golf is played by people riding around in motorized carts; how much exercise could you possibly get?

In Massachusetts Lab, Scientists Grow An Artificial Rat Limb

Originally published on Mon June 15, 2015 7:00 am

In the study, muscle cells were injected into the cell-free "scaffolding" of a rat limb, which provided shape and structure onto which regenerated tissue could grow.

A team of scientists at Massachusetts General Hospital in Boston made news earlier this month when they published research in the journal Biomaterials describing how they'd created the world's first bioartificial limb in the laboratory.

Or, in other words: scientists have now grown the entire forelimb of a rat in a lab.
