Hawaii team going after regional climate patterns of global warming
Energy
Climate models project that the global average temperature will rise about 1°C by the middle of the century, if we continue with business as usual and emit greenhouse gases as we have been. The global average, though, does not tell us anything about what will happen to regional climates, for example rainfall in the western United States or in paradisical islands like Hawai'i.

First measurement of the age of cometary material
Space
Though comets are thought to be some of the oldest, most primitive bodies in the solar system, new research on comet Wild 2 indicates that inner solar system material was transported to the comet-forming region at least 1.7 million years after the formation of the oldest solar system solids.

Can a single layer of cells control a leaf's size?
Plant Biology
Ever looked carefully at the leaves on a plant and noticed their various sizes and shapes? Why are they different? What controls the size and shape of each individual leaf? Very little is known about the developmental control of leaf size and shape, and understanding the mechanisms behind this is a major issue in plant biology.

Animal Behavior
Promiscuous females may be the key to a species' survival, according to new research by the Universities of Exeter and Liverpool. Published today (25 February) in Current Biology, the study could solve the mystery of why females of most species have multiple mates, despite this being more risky for the individual.

Nouns and verbs are learned in different parts of the brain
Neuroscience
Two Spanish psychologists and a German neurologist have recently shown that the brain that activates when a person learns a new noun is different from the part used when a verb is learnt. The scientists observed this using brain images taken using functional magnetic resonance, according to an article they have published this month in the journal Neuroimage.

A Bird With a Big Air-Conditioning Bill
When it comes to keeping cool, toucans get top billing in the animal world. New research shows that the colorful bird uses its massive beak to rapidly radiate away heat, allowing it to chill out in tropical climates or when expending a lot of energy while flying. At its most efficient, the toucan is theoretically capable of jettisoning 100% of its overall body heat loss through its bill.
