The kiwi is a flightless bird found only in New Zealand. They're around the size of a chicken, and lay the largest eggs in relation to their body size of any bird in the world. Their eggs can be up to 20% of the females body weight - the equivalent of a 130 pound woman giving birth to a 26 pound baby.

A Taiwan-based company has built a transparent smartphone with a multi-touch display from a light piece of glass. Although it's still a prototype, the executives have mentioned the transparent smartphone could arrive in late 2013.

Whitening treatments do not permanently whiten teeth. If you expose your teeth to foods and beverages that cause staining you may see the whiteness start to fade in as little as one month after treatment. Those who avoid foods and beverages that stain may be able to wait one year or longer before another whitening treatment or touch-up is needed.
You worked hard to get your teeth white. Here are some tips to help maintain your pearly whites.

• Avoid the consumption of or exposure to products that stain your teeth, such as coffee, tea, and red wine. If you do choose to consume beverages that stain, consider using a straw so that the liquid bypasses your front teeth.
• Brush or rinse immediately after consuming stain-causing beverages or foods.
• Fo

This is the pygmy marmoset (Cebuella pygmaea), the smallest known monkey in the world.

They are found in western Brazil, southeastern Colombia, eastern Ecuador, eastern Peru, and northern Bolivia and they typically live in the understory of the rain forest near rivers. Males weigh around 140 grams (4.9 oz), and females only 120 grams (4.2 oz).

Gallium is a silvery metal with atomic number 31. It is used in semiconductors and LEDs, but the cool thing about it is its melting point, which is only about 85 degrees Fahrenheit. If you hold a solid gallium crystal in your hand, your body heat will cause it to slowly melt into a silvery metallic puddle. Pour it into a dish, and it freezes back into a solid.

While you probably should not lick your fingers after playing with it, gallium is not toxic and it will not make you crazy like mercury does. And if you get tired of it, you can melt it onto glass and make yourself a mirror. ...

Fasciculations (muscle twitches) are the result of some kind of irritability of the nerve fibers. Because fasciculations are benign, they have not been studied particularly deeply (but, not all involuntary muscle twitches are fasciculations--more on that later). So we do not really know even where in the nerve the irritation is picked up--it could be in the cell body, could be further out in the fibers, nobody really knows. It is also thought that the exact localization of the fasciculation is random, meaning that you will feel a twitch in your arm or leg or eyelid without having necessarily irritated a nerve anywhere near the place you experience the twitch.

Causes are also only loosely understood; there are certain behaviors that can trigg ...

Here are some adorable images of macaw parrot chicks getting weighed and measured. The one on the left is just one week old, and the one on the right is seven weeks old.

Researchers at the Tambopata Research Center have been studying the wild macaw populations for years and tracking the growth of the nestlings. By climbing up into the trees and gathering data on these macaws, the researchers are able to do a lot of interesting science and gather information critical to protecting these species. ...

These amazing images of animals in the womb were compiled by scientists using ultrasound scans and computer graphics.
