Countless kids have grown up with the Girl Scouts, the Boy Scouts or Campfire Girls, but for some families, the uniforms and outdoor focus of traditional Scouting groups don't appeal.

In recent months, Scoutlike groups that concentrate on technology and do-it-yourself projects have been sprouting up around the country. They're coed and, like traditional Scouting organizations, award patches to kids who master skills.

Connecticut's chief medical examiner, Wayne Carver, has raised the possibility of requesting genetic tests on Adam Lanza, the man responsible for the shootings at Sandy Hook Elementary School.

Carver hasn't said precisely what he may want geneticists to look for, but scientists who study the links between genes and violence say those tests won't reveal much about why Lanza did what he did.

I love jokes and riddles. Today I want to share one of my favorites. I'll post the answer on Monday.

I first heard this one sitting with friends at an outdoor table during sunset at a village near the shore in Sicily back in 2008. The strange pink color of this morning's sunrise here in Berkeley reminded me of that evening, and the riddle. I think it was my friend Giovanni Frazzetto who offered up the joke. He definitely organized the evening.

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.

Shooting Stars: Capturing The Night On Camera

Originally published on Fri December 21, 2012 4:16 pm

Photographer Colin Legg makes time-lapse movies of celestial scenes, from auroras to eclipses. Photographing mostly in remote parts of Australia, where human-made light doesn't compete with starlight, Legg describes some of the challenges of this type of photography: from babysitting cameras for days and nights on end to running electronics in the backcountry.

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

It's simply a misinterpretation of the Maya calendar, say archaeologists Marcello Canuto and William Saturno.
