Live fast, die old  - Nature  Mice with sky-high metabolic rates live far longer than their sluggish cousins, UK researchers have found, raising the prospect that human lifespan might be lengthened with metabolism-boosting drugs. The group of animals with the highest metabolic rates lived over a third longer than the group with the lowest rates, they found, and had metabolisms that ran about 30% faster. If the same is true in humans, this means that people with a speedy metabolism might add an extra 27 years onto a typical 70-year lifespan. The finding challenges a century-old theory that animals with higher metabolic rates die younger.
Searching Venus's Atmosphere For Signs Of Water Vapor - Science Daily  On June 8 Earth-based solar telescopes will follow a tiny black orb as it appears to travel effortlessly across a wrinkled, brilliant sea. Timothy Brown, a scientist at the National Center for Atmospheric Research (NCAR), will not sit idly by as Venus traverses the Sun for the first time in 122 years at an angle visible from Earth. Peering through a specialized solar telescope in the Canary Islands, Brown will study the chemical composition and winds of Venus's upper atmosphere, a region poorly observed until now. He found sodium in the planet's atmosphere in 2001 and is now searching for water and carbon monoxide.

Microscopic animal fossil, Science

Fossils hint at early complexity  - BBC  Blob-like fossils dating back about 600 million years may indicate that complex life evolved much earlier on our planet than had been thought, scientists say. The animals are less than a fifth of a millimetre long and have a two-sided body plan previously thought to have existed much later in Earth's history. These "bilaterians" have what look like mouths and guts, as well as internal and external layers of body tissue. The age of V. guizhouena suggests the roots of this complexity are much older than had been thought and the Cambrian explosion may not have been quite the sudden burst scientists had believed.
