Did you know?

The Platypus is stranger than you think.

Platypuses have no nipples. After the young hatch, the mother oozes milk from the pores all over her body.

The male platypus has a poison barb on the inside of its hind legs. The purpose of this weapon is uncertain.

While often compared to the beaver, the platypus is only about 20 inches in length -- more comparable to the size of the muskrat.

The Platypus bill is actually just an elongated muzzle covered with much the same kind of tough skin found on a dog's nose. This bill contains an electrically-sensitive organ that can detect the electrical signatures of the small aquatic animals it eats.

Ball-lightning in the laboratory

Scientists in the joint study group of Max-Planck-Institut für Plasmaphysik (IPP) and Berlin’s Humboldt University (HUB) have generated ball-lightning in the laboratory - or, to be more precise, ball-lightning-like plasma clouds. The physicists produce luminous plasma balls above a water surface which have lifetimes of almost half a second and diameters of 10 to 20 centimetres.

[P]Ball-lightning is described as a luminous phenomenon occurring during thunderstorms. It is a mystery, however, that they should be visible not as a brief flash, i.e. just for mi. . .

IMHO, too bad the scientists in the picture aren't wearing labcoats, bug-eyed with excitement....

I'm serious: it would send a message that yes, science can be exiting to young people.

Now you see two common guys just standing there, not even looking on in awe... :(

I saw an article last week sais that the gee-wiz physics demos have an opposite effect: it shows that physics is completely incomprehensible. Maybe this photo is trying to show that you -yes YOU- too can make lightning in your basement! Unless you have anything flammable in your house, in which case it as a bad idea. Bad idea!

Interesting, I wonder how many people have seen this and their retnas have 'burnt' the image in for a couple seconds even though it may have already passed, giving them the impression that it lasted for a few seconds. Is the same lighting that has been reported to 'roll' along the bottom of clouds.
