Shooting Violence: A Reason Why?

November 06, 2009

Horrible news about Fort Hood yesterday. As an alumnus of VA Tech who followed that tragedy from afar, I found this latest shooting extremely painful to watch.  Our hearts go out to the victims and their families and friends.

As we learn more about the identity of the shooter, Maj. Nidal Malik Hasan, we're wondering what drives someone like that to do something so horrible. And is that thing - whatever that thing is - something shared by all people who commit these crimes? And finally - what happens at the breaking point.

To find out, I asked Clinical Psychologist Jill Weber if she had any insight. (You'll need to have Flash enabled to hear them...)

First of all, are there common elements between Hasan and other people like the Columbine shooters?

Jill Weber Answer 1

But lots of people feel marginalized and isolated and they aren't becoming violent...

Jill Weber Answer 2

Reports say that Hasan was a mental health therapist himself, so shouldn't he have had the knowledge and tools to process those feelings?

Jill Weber Answer 3

I asked Weber if there was anything else to add. She said this...

Home Improvement Tips from the Solar Decathlon

October 23, 2009

My house was built in 1941. It's a great little Cape Cod that has everything you need. My only real problem with it is that, quite frankly, it's dumb.

I recently went down to the National Mall in DC on a rainy, overcast day to check out the 2009 Solar Decathlon. And wow - those houses are smart. And filled with cool, green technology. Radiant heat and cooling, induction stovetops, LED lights, and of course solar panels. The systems in these homes talk to the appliances, which talk back to the systems, which talk to you!

So basically, you know how much energy they're using, where it's going, and how you can manage it to leave a smaller carbon footprint. Awesomeness.

And while photovoltaic panels are - yes - still expensive for the average homeowner, there are lots of other things you can add to your house that won't break the bank. And thanks to the folks at the Solar Decathlon, you can get a complete product list on their web site.

Here's the video I produced with Discovery Tech blogger Alyssa Danigelis. Click on the image!

Can Science Explain Public Outbursts?

September 14, 2009

Nothing new about people behaving badly in public – but lately, news headlines seem dominated by sensational stories of outbursts and temper tantrums. 

Tennis star Serena Williams verbally attacking a line judge during the U.S. Open – costing her the match. 

Congressman Joe Wilson shouting “you lie!” at President Obama during President's health care address last week – leaving political decorum on the House floor.

Musician Kanye West climbing on stage to dispute the results of an MTV Video Music Award – humiliating winner Taylor Swift. 

And this was just in the past week! 

I spoke to University of Maryland psychology professor Michael Dougherty to find out if there’s more than just big egos or bad tempers behind these raw moments.

Dougherty says that our brain’s highly developed prefrontal cortex is what helps us control our mental processes… most of the time. But even the occasional outburst is pretty normal human behavior.

The only difference is most of us aren’t pop music stars, pro athletes or politicians. So that little meltdown you had in your car when the driver on your left cut you off? Yeah… that’s not all over YouTube. 

But could this breakdown in social niceties be explained as vestigial behavior carried over from when early man was in constant fight or flight mode?

That’s still probably no excuse for anyone who's ever thrown a chair across a basketball court or yelled at their colleague. But let’s face it, we're emotional creatures, and sometimes they do get the better of us. 

Of course, not every tantrum has to do with stress or fear…

Hmmm... who does that bring to mind?

This Is Your Brain Hearing The Beatles In Stereo. Or Maybe Mono.

September 09, 2009

Trying to decide whether to buy the stereo or mono version of the new Beatles album? Well….we asked Daniel Levitin, Professor of Psychology and Music at McGill University AND the author of This Is Your Brain On Music, what the big difference is between the two as far as your brain is concerned…

So for stereo the record producers virtually “place” each source of sound in a specific location that your brain can detect...the guitar sound is coming from 40 degrees off to your right, the bass is 25 degrees off to your left, etc. With mono there's no differentiation - all the sound comes from the same "location".

He says stereo also sounds more realistic to us…

BUT…how does your brain distinguish what’s coming from where?

All this means I should buy the Beatles album in stereo, right?  Because it’ll sound better that way…or NOT!

So the bottom line is that (in general) stereo mimics how we hear things in nature while mono (in this case) is what the Beatles actually intended us to hear. Do you really want to upset the Beatles???  I asked Levitin which version he chose – mono or stereo?

He took no chances. He bought one of each.

Monkey Music and Metallica

September 02, 2009

Check out this article about monkey music by Jennifer Viegas:

Non-human animals usually prefer silence to our music. However, when cotton-top tamarins heard songs based on their own calls, the diminutive, fluffy primates listened with interest to the monkey music, which even altered their moods, according to a new study.

Here are monkey music samples composed by David Teie used in this research:

Monkey Threat Music!

Monkey Soothing Music!

So how does Metallica fit into the mix? Apparently that was the only human music that soothed the Monkey. If we're talking the guitar solo in Master Of Puppets...I can see their point...it starts at 3:55.

Asteroids, Night Vision, Safer Bridges and Deer Logos!

April 21, 2009

1. Turning asteroids into a game of tetherball

2. Monitoring our bridges... and doing it for free!

3. A secret to night vision found

Here's a video I mentioned on the show that I produced last week that discusses other ways we could fend off rogue asteroids. My fave: painting it.

I mean, when I think of a potential world-killer bearing down on Earth, ready to send us all back to the primordial ooze, the first thing I think is: That asteroid could use a fresh coat of paint. And solar sails. But my real fave idea: putting into orbit with the moon and then mining it for iron, water, oxygen or whatever else is trapped inside. How cool is that?!?

Also, check out this cool image from 12-year-old listener Oliver. It's a live version of our feedbag logo! And with deer to boot! At least, I think those are deer. Or the strangest cows I've ever seen.

Anyway, I challenge our readers to come up with even more inventive ways to stage live versions of the cow logo. But please, keep it safe and keep it legal!

 



 

Susan Boyle sings! What's the science?

April 16, 2009

The internet is abuzz with Susan Boyle's singing talents. The unemployed 47-year-old wowed audiences and judges recently on Britain's Got Talent. Even notorious curmudgeon and judge Simon Cowell (who also portrays notorious curmudgeon and judge Simon Cowell on American Idol), was left nearly speechless by her beautiful singing.

But her talent notwithstanding, what's flooring people most about Susan's story is that she's not - and how do I put this nicely - "attractive" in the classical sense of the word. Her appearance definitely had everyone in the crowd prejudging her abilities, even mocking and snickering at her when she first got on stage. But then she opened her mouth, belted out "I dreamed a dream" from Les Miz like a pro, and SNAP! She shut the world up.

So, amazing as this all is, what's the real science behind singing? Why can some people sing like angels, while others (including me), sound like a bunch of angry cats fighting? Researchers are looking at speech pathology to find out why.

Discovery News' Kasey-Dee Gardner looks into the science of singing in this video:
