Do Animals use Toilet Paper?
|
We investigate the toilet habits of the animal kingdom this week as well as taking a pot shot at which way a dirty golf ball swings in mid air, answering whether warmer waters attract more sharks and if there's a genetic basis to intelligence. We also get an update on what geologists studying the recent earthquake in Haiti are learning from information beamed back from space, and how a new tech-driven initiative called Crisis Camps is helping to streamline aid efforts after a catastrophe. Plus, laser-sensitive nanoparticles that can help to identify tumours, the genome of a 4000 year old man and whether elephants can run...

Surprising as it sounds, scientists at the University of Copenhagen have decoded the genome sequence of an ancient human using hair samples recovered from the permafrost at an archaeological site in Greenland.
High speed elephants have a very strange gait, but do they actually run?

James Jackson explains how satellites can look for changes in landscapes following earthquakes. Spotting patterns in the activity could provide a means to predict future events...
Can people have intelligence passed down genetically? My parents are both fairly knowledgable and can absorb information easily, so since I seem to take after them, is this nature or nurture?
If petroleum is derived from ancient fossilised organic materials, then why do the deposits appear mostly localised in the Middle East?
How do you make an elephant run?
In an article in the December 2009 golf digest, they were talking about a ball with mud on the one side of the ball. Now I would assume with the extra weight on, lets say, the left side, the ball should move toward its left side when hit? They say the opposite. They say mud on th...

Are humans the only animal that needs to wipe its’ bottom?
Are there materials or solid state devices that convert heat directly into electricity? Wouldn't this be better than even zero emissions, as it would reduce the warming effect of cities?
If black absorbs light and white reflects it, why do darker skinned people live nearer to the equator and lighter skinned people further away?
I believe that light is considered to be both waves and particles. My understanding is that particles are physical objects. If that is true, how is light able to travel through glass? Is it just the light waves that travel through glass or can the particles also penetrate glas...

I was wondering how many batteries, for example AA, you can place in series to increase the voltage? What are the limits? Will the current destroy the batteries?
I am a high school student who is currently doing some research on sharks and their connection to global warming. Is there any more data available that could further support the theory that warmer waters are bringing sharks into certain areas? Have there been any reports about ho...
Is it possible to make a phone call from a black hole?
I was told once that sweeteners work because they trigger the same receptors as table sugar (sucrose). My question is, if they trigger the same receptors then why do they taste so different?
