The importance of frogs in the food chain and their surprising role in human medicine is one reason why scientists are hurrying to rescue them from a deadly fungus, and preserve them in "amphibian arks".

Human nature has deep evolutionary roots and is manifested in relationships with family members, friends, romantic and business partners, competitors, and strangers more than in any other aspects of behavior or intellectual activity, contends a University of Chicago behavioral biologist.

The domestication of chickens has given rise to rapid and extensive changes in genome function. A research team at Linköping University in Sweden has established that the changes are heritable, although they do not affect the DNA structure.

“The smell of a body is the (bacteria themselves) which we breathe in with our nose and mouth, which we suddenly possess as though (they) were (the body’s) most secret substance and, to put the matter in a nutshell, its nature. The smell which is in me is the fusion of the (bacteria) with my body…”

In the pioneering days of chronobiology, it was a common practice to go out in the woods and collect as many species as possible and document the existence of circadian rhythms. Technical limitations certainly influenced what kinds of organisms were usually tested.

A team of MIT researchers who recently examined spider webs says the amazing work of nature could improve various human systems, including Internet security and how buildings are designed. Pound-for-pound, the silk which spiders spin is stronger than steel yet it retains a flexibility that is very 'flaw-tolerant'. If one section of the web malfunctions, i.e. is torn away by a bug, the larger integrity of the structure remains. This may help encourage engineers to examine the use of more complex materials when making new designs.

However, specialization of the ant type (though much less extreme) was recently discovered for the first time in a bee species1. The species is Tetragonisca angustula, known to Brazilians as Jataí, and members of the species are small and stingless. The researchers noticed that, given the short 20-day lifespan of an average worker, guards station themselves at the hive entrance for an unusual amount of time. While honeybee workers guard the entrance for only a single day in their sequence of jobs, Jataí guards stay for at least five. Combined with the observation that guards appear larger than foragers (the other, larger group of bees), this led them to hypothesize that guards are a separate caste.
