"Almost half the children committed one or more of these mistakes. They attempted with apparent seriousness to perform the same actions with the miniature items that they had with the large ones. Some sat down on the little chair: they walked up to it, turned around, bent their knees and lowered themselves onto it. Some simply perched on top, others sat down so hard that the chair skittered out from under them. Some children sat on the miniature slide and tried to ride down it, usually falling off in the process; others attempted to climb the steps, causing the slide to tip over.
(With the chair and slide made of sturdy plastic and only about five inches tall, the toddlers faced no danger of hurting themselves.)"

Scientific American to stop reporting science, more creationism. There's no easy way to admit this. For years, helpful letter writers told us to stick to science. They pointed out that science and politics don't mix. They said we should be more balanced in our presentation of such issues as creationism, missile defense and global warming...But spring is in the air, and all of nature is turning over a new leaf, so there's no better time to say: you were right, and we were wrong.

Advanced methods of bomb detection and investigation.
New equipment developed to scan cars and people, such as a parking lot device which quickly bathes the car's trunk in invisible neutrons, a procedure that makes materials inside the trunk emit gamma-rays
that would indicate the presence of explosives.
Also, a bomb disposal robot which take[s] fingerprints before blowing [a] package up

15 Answers to Creationist Nonsense
From Scientific American..."Opponents of evolution want to make a place for creationism by tearing down real science, but their arguments don't hold up.
Besieged teachers and others may increasingly find themselves on the spot to defend evolution and refute creationism. The arguments that creationists use are typically specious and based on misunderstandings of (or outright lies about) evolution, but the number and diversity of the objections can put even well-informed people at a disadvantage.
To help with answering them, the following list rebuts some of the most common "scientific" arguments raised against evolution. It also directs readers to further sources for information and explains why creation science has no place in the classroom."

Some naval experts believe that supercavitating systems could alter the nature of undersea warfare, changing stealthy cat-and-mouse stalking contests between large submarines into something resembling aerial combat, featuring noisy high-speed dogfights among small, short-range "subfighters" shooting underwater bullets at one another after having been launched from giant "subcarriers."
