And scientific researchers appear to be slowly conceding that zoophilia may be a genuine human sexual orientation.
Scientific American's Jesse Bering research into zoophiles, prompted by a "an unusually erudite reader ... a self-professed zoophile" leads to more questions than answers: Are zoophiles attracted only to sexually mature animals—and if not, does this make them “zoopedophiles”? Do zoophiles find particular members of their preferred species more “attractive” than other individuals from those species, and, if so, are they seduced by standard beauty cues, such as facial symmetry in horses? What is the percentage of homosexual zoophiles (those who prefer animal partners of the same sex) over heterosexual zoophiles?

"He asks each of them to write down...any dollar integer between 2 and 100 without conferring together. If both write the same number...he will pay each of them that amount. But if they write different numbers, he will ... pay both of them the lower number along with a bonus and a penalty--the person who wrote the lower number will get $2 more...and the one who wrote the higher number will get $2 less.... For instance, if Lucy writes 46 and Pete writes 100, Lucy will get $48 and Pete will get $44."
What amount would you choose?
And what does your answer tell us about the limits of Game Theory

"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

In an infinite universe
there's a copy of you reading this post - in Latin. The Scientific American updates current cosmological thinking on Parallel Universes - The key question is not whether the multiverse exists but rather how many levels it has
- and reaches some startling conclusions.

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."

"We have entered the Century of the Environment,
in which the immediate future is usefully conceived as a bottleneck: science and technology, combined with foresight and moral courage, must see us through it and out."
Or so says Edward O. Wilson in February's Scientific American. Consumption and production can NOT be infinite, no matter what "near-horizon timelines" predict. But will capitalism rise to the occasion and will the free market fix the wrongs it's committed?

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."

A Scourge of Small Arms
"The root causes of ethnic, religious and sectarian conflicts around the world are of course complex and varied, typically involving historical grievances, economic deprivation, demagogic leadership and an absence of democratic process. Although small arms and light weapons are not themselves a cause of conflict, their ready accessibility and low cost can prolong combat, encourage a violent rather than a peaceful resolution of differences, and generate greater insecurity throughout society--which in turn leads to a spiraling demand for, and use of, such weapons."
