'Adaptation to exercise' is a familiar phenomenon, even if the phrase is not: A sedentary person takes up jogging and can barely make it around the block. After jogging regularly for a few weeks, the person can jog a mile, then two, then three. With regular exercise, the body adapts, becoming fitter and more efficient. The heart can pump more blood, delivering more oxygen to the muscles. The muscles get stronger, and so on.

A lack of Vitamin D, due to reduced sunlight, has been linked to depression and the symptoms of Seasonal Affective Disorder (SAD), but research by the University of Warwick shows there is no clear link between the levels of vitamin D in the blood and depression.

Exposure to sunlight stimulates vitamin D in the skin and a shortage of sunlight in the winter has been put forward as one possible cause of SAD. However Warwick Medical School researchers, led by Dr Oscar Franco, have discovered low levels of vitamin D in the blood may not be connected to depression.

Researchers trying to uncover the mechanisms that cause attention deficit hyperactivity disorder and conduct disorder have found an abnormality in the brains of adolescent boys suffering from the conditions, but not where they expected to find it.

Boys with either or both of these disorders exhibited a different pattern of brain activity than normally developing boys when they played a simple game that sometimes gave them a monetary reward for correct answers, according to a new study by a University of Washington research team.

The International Institute for Species Exploration at Arizona State University and an international committee of taxonomists – scientists responsible for species exploration and classification – today announce the top 10 new species for 2009, consisting of those described in 2008.

How were the Top 10 chosen?

The International Institute for Species Exploration at Arizona State University and an international committee of taxonomists – scientists responsible for species exploration and classification – today announce the top 10 new species described in 2008.

The International Institute for Species Exploration at Arizona State University and an international committee of taxonomists – scientists responsible for species exploration and classification – today announce the top 10 new species for 2009, consisting of those described in 2008.

On the list are a pea-sized seahorse, caffeine-free coffee and bacteria that live in hairspray. The top 10 new species also include the very tiny (a snake just a slither longer than 4 inches or 104 millimeters), the very long (an insect from Malaysia with an overall length of 22.3 inches or 56.7 centimeters) the very old (a fossilized specimen of the oldest known live-bearing vertebrate) and the very twisted (a snail whose shell twists around four axes).

It is the concentration of a few signaling molecules that determines the fate of individual cells during the early development of organisms, say a team of molecular biologists writing in Current Biology.   Pia Aanstad of the University of Innsbruck and colleagues report that a variety of molecular mechanisms accounts for the interpretation of the concentration of the signaling molecule Hedgehog. 

The development of an organism is a complex process to which a dozen or hundreds of signaling molecules contribute. Some of these molecules have dozens of functions in the fruit fly and in humans alike.
