The 4th Annual Kids’ Science Challenge

Kids' Science ChallengeRegistration for the Kids’ Science Challenge, a free nationwide competition for 3rd to 6th graders, opened today for it’s fourth year. The competition gives kids the opportunity to submit experiments and problems for real scientists and engineers to solve. Plus kids can play science games, watch videos, and enter to win awesome prizes and trips.

This year’s topics:

  • Zero Waste
  • Animal Smarts
  • Meals on Mars

Through the competition kids research these topics, brainstorm ideas, and submit their experiments or problems for scientists to solve. The winning students are given the opportunity to work with real scientists to bring their ideas to life.

The first 1,000 entrants receive a free science activity kit with hands-on projects related to the three science topics. Other prizes include science kits, science equipment and cool science toys.

The competition is open between October 1, 2011 and February 29, 2012.

Visit the site for more information, visit their website or follow them on Facebook.

Good luck to all that enter!

Disclosure: Edmund Scientific has provided some of the great prizes for this competition.

Neutrinos Faster Than Light?

Researchers at CERN released a statement that an experiment had recorded subatomic particles, known as neutrinos, traveling faster than the speed of light.

The result, if confirmed, would upend the field of physics, as Einstein’s theory of relativity is based on the idea that nothing can travel faster than light.

“This result comes as a complete surprise,” said Antonio Ereditato of the University of Bern, a spokesman for the experiment, in a statement on the CERN web site. “After many months of studies and cross checks we have not found any instrumental effect that could explain the result of the measurement.” However, he added, “the potential impact on science is too large to draw immediate conclusions or attempt physics interpretations.”

Fatherhood, Not Testosterone, Makes The Man

Me and my girls in Rhode Island

A study in the Proceedings of the National Academy of Sciences says that when men become fathers, their testosterone levels drop significantly. Not shocking news, if you are already a dad, right?

The study, led by Dr. Lee Gettler of Northwestern University, followed the testosterone levels of 600+ Filipino men from when they were 21 until five years after becoming fathers. The results showed that the testosterone level dipped as much as 34 percent in the men who became fathers, with the biggest change occurring in men who spent a lot of time caring for their children.

A few quotes from the NPR article:

“There’s something about being an active father that’s contributing to these dramatic declines,” said Dr. Gettler, who headed the study.

Anthropologist Peter Gray at the University of Nevada told The New York Times, “A dad with lower testosterone is maybe a little more sensitive to cues from his child, and maybe he’s a little less sensitive to cues from a woman he meets at a bar.”

As a very involved father of three toddle girls, I can’t say I am surprised, but it does explain a lot of things. At least I now have an excuse the next time a non-father buddy catches me playing dress-up with the girls.

Black Hole Jets

Researchers have observed the inner parts of a black hole’s active jets for the first time, suggesting “that the energetic spouts are more dynamic than previously suspected, with enormous blasts firing off randomly over timescales as short as 11 seconds.”

The black hole was observed by NASA’s Wide-field Infrared Survey Explorer (WISE) spacecraft and is located 20,000 light-years away near the center of the galaxy.

From the Wired article:

Researchers were able to determine that the jets are emitted from an area approximately 15,000 miles across, though the size of this region sometimes rapidly increased by an order of magnitude or more. They were also able to make detailed measurements of the black hole’s magnetic field, which is 30,000 times more powerful than the Earth’s. Since the magnetic field is thought to be, in part, responsible for the powerful jets, this data could help astronomers understand the inner workings of these exotic phenomenon.
