Good lighting and high resolution cameras in the SMART-1 satellite are making it possible to put together the story linking geological and volcanic activity on the Moon.

“Thanks to low-elevation solar illumination on these high-resolution images”, says SMART-1 Project Scientist Bernard Foing, “it is now possible to study fine, small-scale geological features that went undetected earlier.”

The study provides new information on the thermal and tectonic history of the Moon and the processes following the formation of the large basins. There are approximately 50 recognizable lunar basins more than 300 km in diameter.

Researchers at the University of Illinois at Chicago have discovered a chemical compound in male blue crabs that is not present in females -- the first time in any species that an entire enzyme system has been found to be activated in only one sex.

The research, performed using nuclear magnetic resonance, was published online Aug.

Cooperation is widespread in the natural world but so too are cheats – mutants that do not contribute to the collective good but simply reap the benefits of others’ cooperative efforts. In evolutionary terms, cheats should indeed prosper, so how cooperation persists despite the threat of cheat takeover is a fundamental question. Recently, biologists at the Universities of Edinburgh and Oxford have found that in bacteria, cheats actually orchestrate their own downfall.

In the study, reported in the September issue of The American Naturalist, the team explored the impact of cheats in populations of the notorious pathogen, Pseudomonas aeruginosa.

Planning for a summer delivery for your child? You might want to choose an ophthalmologist along with an obstetrician.

If your child is born in the winter or fall, it will have better long-range eyesight throughout its lifetime and less chance of requiring thick corrective glasses, predicts a Tel Aviv University investigation led by Dr. Yossi Mandel, a senior ophthalmologist in the Israel Defense Forces Medical Corps.

Forming a large multi-center Israeli team, the scientists took data on Israeli youth aged 16-23 and retroactively correlated the incidence of myopia (short-sightedness) with their month of birth. The results were astonishing.

Researchers at BRIC, University of Copenhagen, have identified a new gene family (UTX-JMJD3) essential for embryonic development. The family controls the expression of genes crucial for stem cell maintenance and differentiation, and the results may contribute significantly to the understanding of the development of cancer.

All organisms consist of a number of different cell types each producing different proteins. The nerve cells produce proteins necessary for the nerve cell function; the muscle cells proteins necessary for the muscle function and so on. All these specialized cells originate from the same cell type – the embryonic stem cells.

Neuroscientists at University College London and Ghent University have found the brain circuit involved in thinking twice and checking impulsive behaviour. The duo discovered that an area in the fronto-median cortex of the brain is activated when you begin to think ‘I’m not going to go through with this’ and stop yourself doing what you were about to do.

According to the study, published in the ‘Journal of Neuroscience’ today, this specific brain network is involved in self-control and checks and limits our desired actions.
