Puberty Is Coming Earlier, But That Doesn't Mean Sex Ed Is

Originally published on Thu October 17, 2013 5:54 pm

A growing number of children are entering puberty at younger ages — sometimes as young as 6 or 7. But in many schools, sex education classes don't begin before the fifth grade.

For kids growing up in the San Francisco Bay Area, there's a standard introduction to puberty at many schools: an educational play called Nightmare on Puberty Street.

It's a fictional play, and in it, character Natalie raps about how quickly her body is growing — and how her classmates call her names.

"I didn't pick how my body would grow, and I don't feel normal, 'cause I'm not in control."

When a mud volcano erupted last week and created a muddy mound of an island just off the southern coast of Pakistan, it seemed to us like a rather rare development.

But it turns out islands crop up fairly often. Charles Darwin commented on one. And it's been happening in shallow marshy patches off the coasts of Sweden and Finland for millennia.

If you're suffering withdrawal symptoms from the National Zoo's "pandacams" — sadly deemed "nonessential" and therefore shut down, along with much of the rest of the government — we have the perfect antidote:

Scientists are reasonably sure that it's a cloudy day on Kepler-7b, a planet that orbits its star about 1,000 light-years away from us.

Using NASA's orbiting space telescopes, researchers publishing in Astrophysical Journal Letters say that for the first time they've been able to make a rudimentary map of the atmosphere of an extrasolar planet.

The team used faint visible light and infrared reflections from Kepler-7b to make their cloud map.

Scientists think they've identified the source of a massive volcanic eruption that occurred in A.D. 1257 and spread telltale traces across the globe.

The culprit in the "mystery eruption" appears to be the Samalas volcano, part of the Mount Rinjani Volcanic Complex on Indonesia's Lombok Island, an international team of scientists publishing in PNAS journal says.

Here's Something Congress Can Agree On: Helium

Originally published on Tue October 1, 2013 5:03 pm

Party On: Legislation passed last week allows the Federal Helium Reserve to continue selling the stockpiled gas. Above, Jonathan Trappe launches his 370-balloon craft from Caribou, Maine, in an attempt to cross the Atlantic Ocean on Sept. 12.

With the government on the brink of a shutdown, Republicans and Democrats in Congress have come together to compromise on helium. Legislation passed late last week will keep the gas used in party balloons flowing from a national reserve.

The helium bill's passage shows that compromise is still possible in the fractious political climate. But finding agreement over this inert gas was tough. The new law came after more than a year of intensive lobbying by some of America's largest businesses and academic institutions.

If you got sick, you probably wouldn't go to an evolutionary biologist to get treated. But Daniel Lieberman, professor of evolutionary biology at Harvard University, says that his field can help you understand why you got sick, and make you more aware of healthy and harmful behaviors.
