Imagine nature's most elegant ideas organized by design and engineering function, so you can enter "filter salt from water" and see how mangroves, penguins, and shorebirds desalinate without fossil fuels. That's the idea behind AskNature, the online inspiration source for the biomimicry community. The featured pages are a good starting point. Cross-pollinating biology with design. [more inside]

On Growth and Form (1917) was D'Arcy Wentworth Thompson's pioneering effort to explore the mathematical principles that underlie biological form. He studied the similarity between the shapes of a jellyfish and a drop of ink, a splash and a hydroid, between dragonfly wings and bubble froth, the growth of radiolaria and snowflakes, the spirals of nautilus and mollusk shells and sheep horns. More recently, Adrian Bejan's Constructal Theory aims to explain all biological shape from one thermodynamic principle. This month there is an interview with Bejan for the layman. [more inside]

Hunting the Hidden Dimension. You may be familiar with fractals, but in this PBS Nova episode, divided online into 5 parts, fractals go beyond the impossible zoom of the Mandelbrot set. Scientists are using fractals to describe complex natural occurrences, like lava, capillaries, and rain forests. In part 5, scientists measure one tree in the rain forests, and the distribution of small and large branches mirror the distribution of small and large trees. Fractals, it seems, are nature.

"With most animals, males duke it out and the winner gets the girls," says Holekamp. "But with hyenas, females have 100 percent say." They decide when and under what conditions they will tolerate deferential sperm donors. At age 2 or 3 a male leaves his natal clan and wanders off to beg acceptance into another clan. After vicious rejections, he eventually succeeds and reaps his reward: brutal harassment as the clan's nadir, one of the last in line for food and sex. This probation, which biologists call "endurance rivalry," is a test, Holekamp explains: "The guy who can stick it out the longest wins." The trial lasts about two years, after which some females may grant him access. "You do not want to be a male hyena," Holekamp says.-From an article in Smithsonian Magazine, Who's Laughing Now? Professor Holekamp's hyena site. Also, hyena pictures and The Hyena Pages, a fine site about this fascinating animal.
While the dream of immortality might be as old as mankind, the jellyfish Turritopsis nutricula (image) seems to be living it:
The hydrozoan Turritopsis nutricula has evolved a remarkable variation on this theme, and in so doing appears to have achieved immortality. The solitary medusa of this species can revert to its polyp stage after becoming sexually mature (Bavestrello et al., 1992; Piraino et al., 1996). In the laboratory, 100% of these medusae regularly undergo this change. Thus, it is possible that organismic death does not occur in this species!An in-depth research paper.

Birds that rap and cows with accents. The big picture is urban adaptation, which is pretty cool. (...and the egg wins.)

Female X chromosome 'cracked' - "The discovery, by an international consortium of scientists, shows that females are far more variable than previously thought and, when it comes to genes, more complex than men." Nature reports two new studies; one on the complete sequencing of the X chromosome for humans, which sheds some light on how sex evolved and how women differ from men, and another on how women express many genes from X chromosomes previously thought dormant.

"Infrasonic Symphony" Intrigued by reports of tsunami-avoidance behavior in Sri Lankan wildlife? Science News offers a timely antidote to simplistic mumbo-jumbo about the "mythical power" of animal earthquake detection with a detailed look at the latest research into low-frequency sound. The Elephant Listening Project is particularly interested in elephant rumblings that produce Rayleigh waves. "Mammals, birds, insects, and spiders can detect Rayleigh waves," notes The Explainer. "Most can feel the movement in their bodies, although some, like snakes and salamanders, put their ears to the ground in order to perceive it."

Crows better than chimps at making tools? British scientists were reportedly "astonished" when a captive crow named Betty "spontaneously bent a straight piece of wire and used it to retrieve a snack." But another scientist says crows have been seen making two kinds of hook tools in the wild, although he's not sure we should say they have "insight." It's clear that there are lots of different kinds of animal intelligences, so why are humans so surprised when dolphins recognize themselves in mirrors, chimps demonstrate culture and lions engage in social problem-solving? What explains the reluctance to admit that animal "consciousness" exists?

Buddhist mandalas? Abstract doodles? Alien snow crystals? Nope. Just some amazing scientific art from Art Forms in Nature, published between 1899 and 1904 by zoologist Ernst Haeckel. Lots more early biological art at this scientist's public domain archive. Unfortunately, Haeckel also helped provide the philosophical foundation for Nazism. Hey, no one's perfect.
