Talking plants
When South African botanist Lyall Watson claimed in his 1973 best-seller “Supernature” that plants had emotions that could register on a lie detector, scientists scoffed and branded it hippie nonsense. But new research at The University of Western Australia has discovered that plants appear to react to sounds and may even make clicking noises to communicate with each other.
UWA Postdoctoral Research Fellow, Dr Monica Gagliano has teamed with colleagues Professor Daniel Robert at the University of Bristol (UK) and Professor Stefano Mancuso at the University of Florence (Italy) to show that the roots of young plants emit and react to particular sounds.
“Everyone knows that plants react to light, and scientists also know that plants use volatile chemicals to communicate with each other, for instance, when danger - such as a herbivore - approaches,” Dr Gagliano said. “I was working one day in my herb garden and started to wonder if maybe plants were also sensitive to sounds - why not? - so I decided as a scientist to find out.”
Dr Gagliano and fellow researchers established that young roots of corn made regular clicking sounds. They also found that young corn roots suspended in water leaned toward the source of a continuous sound emitted in the region of 220Hz, which is within the frequency range that the same roots emitted themselves.
Their findings, published in the leading international journal Trends in Plant Science, conclude that the role of sound in plants has yet to be fully explored, “leaving serious gaps our current understanding of the sensory and communicatory complexity of these organisms”.

Corn #1: I like Bruno Mars… His song said we were “a-maize-ing” just the way we are ^_^”
Corn #2: Dude, you’re too corny!

In Space, There Is No Up or Down
Former ISS astronaut André Kuipers took this photo of an air bubble inside of a water droplet on a previous expedition, proving that hanging out in space is every bit as fun as you’d imagine it is. But he also provides us with a fun way to illustrate a physical principle of light and optics: refraction.
When light passes from one medium to another, like air-to-water or water-to-air, it is bent. Different wavelengths are bent at different angles in different media depending on the angle of the light hitting the interface between, say, air and water. It’s all laid out in something called Snell’s Law, if you’re interested.
So light from André’s particularly shiny noggin is bent down when it enters the water, and light from his chin is bent up. And when the light waves in water re-enter the air, the whole process is flipped again thanks to inverse refraction.
The result is a man with a squashed face trapped inside a tiny bubble floating through space … and this very cool photo.

Look at this program. LOOK AT IT
- It’s a great reference for drawing heads in different angles
- It has at least 100 sliders, so you can
recreate your fictional crush create many original characters
- IT HAS A FREE VERSION
So basically, this program is the best
GO ON DOWNLOAD IT
whoa, this was used for Skyrim? AWESOME
*downloads* …and now i can make up for my lack of people-drawing ability and just use this and fill in the background.
