Neuroscientists at Johns Hopkins have discovered that mice lacking an enzyme that contributes to Alzheimer disease exhibit a number of schizophrenia-like behaviors. The finding raises the possibility that this enzyme may participate in the development of schizophrenia and related psychiatric disorders and therefore may provide a new target for developing therapies.

The BACE1 enzyme, for beta-site amyloid precursor protein cleaving enzyme, generates the amyloid proteins that lead to Alzheimer’s disease. The research team years ago suspected that removing BACE1 might prevent Alzheimer.

“We knew at the time that in addition to amyloid precursor protein, BACE1 interacts with other proteins but we didn’t know how those interactions might affect behavior,” says Alena Savonenko, M.D., Ph.D., an assistant professor in neuropathology at Hopkins.

Chile’s Chaiten Volcano is shown spewing ash and smoke (centre left of image) into the air for hundreds of km over Argentina’s Patagonia Plateau in this Envisat image acquired on 5 May 2008.

The 1000 m-high volcano had been dormant for thousands of years before erupting on 2 May, causing the evacuation of thousands. Chaiten Volcano is located in southern Chile 10 km northeast of the town of Chaiten on the Gulf of Corcovado.

Envisat’s Medium Resolution Imaging Spectrometer (MERIS) instrument processed this image at a resolution of 1200 m.

Would you recognize a legislative push for Creationism if you saw one? After decades of failed legal strategies to overtly ban evolution or make equal time for Creationism in public schools, the latest tack used by the opponents of evolution is to have 'academic freedom' bills that encourage school teachers to include supposed evidence against evolution, or the presentation of 'both sides' of a controversial issue in science class. If you support the integrity of science education, you should oppose bills like this, both because they are redundant when it comes to good science (teachers already can teach both scientific sides of a legitimate scientific debate), and because the Creationist legislators pushing them are up to no good. But are we reaching a point where Creationism is defining itself out of existence? Are they creating a legal loophole too small for their anti-evolutionary propaganda to fit through?

Scientists used to think that hermaphrodites, due to their low position in the evolutionary scale, did not have sufficiently developed sensory systems to assess the “quality” of their mates.

A new work has shown, however, that earthworms are able to detect the competition by fertilising the eggs that is going to find its sperm, tripling its volume when there is rivalry. This ability is even more refined as they are able to transfer more sperm to more fertile partners.

Hermaphrodites, organisms that have both female and male reproductive organs, such as earthworms, are denied the right to choose their partner. However, a study by researchers at the University of Vigo has shown that worms are capable of telling whether another worm is a virgin or not, and triple the volume of sperm transferred during copulation if they detect a fertilisation competition risk.

You wouldn't think that clean air would be bad for the Amazon rainforest but UK and Brazilian climate scientists writing in Nature say just that.

Reduced sulphur dioxide emissions from less burning coal and increased sea surface temperatures in the tropical north Atlantic, are causing a heightened risk of drought in the Amazon rainforest.

A team from the University of Exeter, Centre for Ecology and Hydrology, Met Office Hadley Centre and Brazilian National Institute for Space Studies used the Met Office Hadley Centre climate-carbon model to simulate the impacts of twenty-first century climate change on the Amazon rainforest. They compared the model to data from the 2005 drought, which caused widespread devastation across the Amazon basin.
