The National Academy of Sciences has a great online interactive tool called “I Was Wondering…“, which highlights the contributions of women in science. The site includes features on cool female scientists, a timeline of their discoveries, and games. Also, there’s a section called “Ask It!” where readers can submit their own questions.

The site, based on this series of books, is targeted toward tween girls:

What would it be like to build the first robot that could interact with people? Or to study human remains in search of criminal evidence? In Women’s Adventures in Science, readers will learn about the trailblazing women who are leaders in a variety of scientific fields, from robotics to forensics.

The site looks like a lot of fun and I hope that it inspires more young girls to embrace science.

A recent Dutch study has concluded that nearly 1 in 10 children aged seven to eight hear voices, but most aren’t bothered by them. About 3,800 children were surveyed and asked whether they heard one or more voices that only they themselves could hear.

Nine percent of the children answered yes. Only 15 percent of these children said the voices caused them serious suffering, and 19 percent said the voices interfered with their thinking. Boys and girls were equally likely to report hearing voices, but girls were more likely to report suffering and anxiety due to the voices.

I don’t quite know what to make of this information. This seems like a lot of kids. I’m a bit skeptical that there weren’t some children answering in the affirmative just for attention, or perhaps seeking approval. After all, we’ve seen many examples of the power of suggestion over people.

However, even if the numbers are reliable, experts say not to panic if your child hears voices. They conclude that most children suffering from auditory vocal hallucinations will not have any long-term effects from the condition. One of the study’s authors, Agna A. Bartels-Velthuis of University Medical Center Groningen in The Netherlands, said, “In most cases the voices will just disappear. I would advise them to reassure their child and to watch him or her closely.”

Perhaps these hallucinations account for some of the children who are attributed with “special gifts” such as psychic abilities? Many kids claim to have imaginary friends; but, perhaps, to some children, these friends are not really imaginary. Rather, they are voices inside their heads. It’s interesting research.

The team plans on following up in a few years to study how the auditory hallucinations evolve and what effect, if any, they have on the child’s behavior.

The 3rd annual “Doodle 4 Google” contest begins today. Kids in grades K-12 can design their very own Google logo and the winner will have it displayed on Google.com for a day. They win other cool stuff, too:

In addition to the winner’s art appearing on Google.com on May 27, 2010, they’ll also receive a $15,000 college scholarship, a laptop computer and a $25,000 technology grant for their school.

Not too shabby.

The theme this year is “If I Could Do Anything, I Would…” and doodles must be submitted by March 31, 2010. It’s great that Google celebrates creativity in kids. If you’ve got a young designer or doodler at home, this could be a fun project.

Andrew Wakefield kicked off the anti vaccination movement with his paper published in 1998 that claimed to show a link between Autism and vaccines. His  findings  have been proven false over and over again. It was also found that he most likely faked his data.

Last week  the UK’s General Medical Council found that Andrew Wakefield acted “dishonestly and irresponsibly” when doing his research. And now The Lancet (who published the paper) has issued a full retraction.

This is very good news and I hope that this will help put parents concerns about vaccinating their children to rest.

In other news, Bill Gates has committed $10 Billion (yes Billion!)  to develop and deliver vaccines to children in the developing world. “We must make this the decade of vaccines,” said Bill Gates. “Vaccines already save and improve millions of lives in developing countries. Innovation will make it possible to save more children than ever before.”

I get a daily email from the American Council on Science and Health called “Health Facts and Fears”. In that news letter Dr Gilbert Ross is quoted as saying of Bill Gates, “We must give credit to him for taking a very effective, targeted, lifesaving approach to charitable giving as opposed to activists, who prefer to wage irrational attacks on substances that have no nexus with human health.”

This is a great story. It’s about a former New Orleans Saints cheerleader who also happens to be an analytical chemist at DuPont. Surprised? We shouldn’t be. She said:

I danced with several girls who had their PhD’s, Masters etc and it’s our obligation to share this duality with the public in an effort to help young girls feel comfortable following all of their dreams (and to help them understand how important education is and frankly how much fun science can be).

I couldn’t agree more.

Many people are shocked when sexy women are also smart. In fact, the woman in the article said she almost didn’t get hired at a science job because of the NFL cheerleader line on her resume.

It’s a pervasive stereotype in our country. Admit it–you laughed at the idea of Denise Richards as a nuclear physicist in The World is Not Enough. (Well, her character’s name of “Dr. Christmas Jones” didn’t help.) So it’s nice to see some non-Hollywood examples of real brains and beauty.

Since we’ve recently been discussing education and girls, I saw this and had to share. Here is a mudflap I can get behind:

It’s a girl reading a book and it’s pretty awesome. The sticker is only $4, and you can buy it at CafePress.

I was a little disappointed in Pro.Con.org’s article, “Should any vaccines be required for children?” I first discovered this site while job hunting and was impressed. Unfortunately, if you check out the pro and con list for this subject, you will see the same tired and debunked arguments against vaccines, including the utter myth that thimerosal is linked to autism.

If you go, put some comments on the pro side. I understand that this site wants to present a balanced argument, but is it balanced if one side is simply wrong about their facts?

Recently, my son’s daycare updated their vaccination records, and we realized that we only had two of his required Hepatitis B vaccinations on record. I had to go to the hospital where he was born and inquire with medical records to see if he received this vaccination at birth. While I thought the HepB vaccination at birth was standard, there is some question about whether our birth hospital actually performed it. We’ll see when the records come in the mail.

We also faced having to switch pediatricians lately due to an insurance change, so I explained the situation to our new pediatrician, a grandfatherly gentleman who was nice enough to sit with us and talk about our son for a length of time defying the normal HMO visit. “I wouldn’t worry about that shot immediately,” he said, “unless your son is planning to get a tattoo soon.”

Among parents who question the standard vaccination schedule, the Hepatitis B vaccine at birth is a frequently discussed topic. I see it pop up often on Mommy chat boards. Most parents don’t really see the urgency of innoculating a newborn against a disease that is primarily transmitted through sexual contact or injection.

Joseph Albietz explains the rationale behind the US HepB vaccination schedule in a November post on Science Based Medicine. This is a concise article that clarifies the public health strategy behind the decision to vaccinate infants at birth. I read the post with great interest, but it was only my recent investigation into my own son’s HepB records that reminded to post the article here today.

To sum it up, vaccinating only a high risk population was a strategy that was tried in the US and then abandoned as not effective enough. Given that the HepB vaccine is incredibly safe, the morbidity and mortality of HepB is substantial, and that the number of cases of HepB has been dramatically reduced using the current strategy–”from 10.7/100,000 in 1983 to 2.1 per 100,000 in 2004. (25,916 total cases down to 6212 cases)”–it makes sense to vaccinate against this disease at birth. There is also the issue that although children make up a small portion of those infected, they tend to become lifelong carriers more often than infected adults.

One of the questions many parents ask (and the question Albietz is responding to in this post) is about the US vaccination strategy verses other countries, specificially those in Northern Europe. Those countries have such a low incidence of the disease that a prevention strategy like that of the US is not cost effective.

Very interesting reading. I hope you will click over and enjoy the entire post.

Maggie Koerth-Baker over at BoingBoing is doing a great series of monthly science questions from kids. This month’s question is about the color of light:

Why does a glow-in-the-dark Frisbee glow green? Why does a spark from a light socket look blue? Two different questions, but one intertwined answer.

I like that the answers are written so that both adults and kids can understand the concepts. It’s a great series. If you’ve missed any of the other questions, here are some of my favorites:

• Why is Poop Brown?
• What Do Blind People See?
• Omnivore Dinosaur

I have been saying for years that students are influenced by American society to think math is hard. People tell them math is hard, so they think math is hard, so they don’t do well in math. I even remember writing an essay on a college math final in which I ranted about this very topic.

I collected anecdotal evidence to support my theory when, as a grad student, I tried to teach elementary education majors some rudimentary physics labs. The class, which was a light version of Physics 101, designed just for elementary education majors, was required for the degree. Many of the students would put the class off until their final semester, and viewed it as a major obstacle to graduating. They had poor attitudes, because the subject was “so difficult”, and besides, “when would they ever use it”? They came into the class convinced that the subject, and the necessary math, was too hard, and they couldn’t do, and they’d never use it as a teacher. Let me rephrase that: they thought that physics, the basic science behind everything in the universe, was not only impossible, it was unnecessary, to learn. These people now teach our children.
