Fifty Years With Double Stranded RNA
Alexander Rich, the scientist who discovered hybridization and the "other" double helix describes what it meant to biology.

Bioengineering and AIDS
University of Utah scientists designed a "molecular condom" women could use daily to prevent AIDS by vaginally inserting a liquid that would turn into a gel-like coating and then, when exposed to semen, return to liquid form and release an antiviral drug.

Genetic Map Offers New Tool For Malaria Research
In one of three genomic studies of malaria appearing in Nature Genetics, scientists chart genetic variation across the genome of the malaria parasite, unlocking novel DNA regions associated with drug resistance.

Laugh And The Whole World Laughs With You: Why The Brain Just Can't Help Itself
Researchers at UCL (University College London) and Imperial College London have shown that positive sounds trigger a response in the listener's brain in an area that is activated by smile, as though preparing our facial muscles to laugh.

This Holiday Season drink without fear.
A study performed by the Research Laboratories of the Catholic University of Campobasso (Italy) confirms the beneficial effects that moderate consumption of alcohol has on our health: drinking in moderation reduces all-cause mortality.

Another reason why the Octopus Rules - in built 3-D light reflectors!
Roger Hanlon at the Marine Biological Laboratory, Woods Hole, Massachusetts and colleagues took a close look at the octopus's skin and identified a new group of proteins (leucophores) with remarkable properties.

New Insights Into The Origin Of Life On Earth
In an advance toward understanding the origin of life on Earth, scientists have shown that parts of the Krebs cycle can run in reverse, producing biomolecules that could jump-start life with only sunlight and a mineral present in the primordial oceans.

Found : Apple Gene for Red
CSIRO scientist have found the gene that controls the color of apples. The red color of apple skin is result of anthocyanins (responsible for blue or red color in plants). It was known that color of apples is affected by light (less light results in poor color), so the scientist looked for genes that were activated by light and compared these to genes in a green apple and bingo!


Learning During Sleep?
Max Planck Institute for Medical Research in Heidelberg have taken a step towards understanding communication between memory areas. Their study shows a link between sleep and memory consolidation (transfer of memory from hippocampus to the cerebral cortex).

Cities Change The Songs Of Birds Leiden University researchers studied the songs of the great tit (Parus major), a successful urban dweller in the center of ten major European cities and compared the songs to that of the bird living in nearby forest sites. The results show that songs that are important for mate selection or territory defense are shorter, sung faster and at a higher pitch by the urban bird. The findings published on Dec.5 in Current Biology show divergence within a species because of the environment and could very well lead to speciation.

NASA Telescope Sees Black Hole Munch On A Star.
NASA’s Galaxy Evolution Explorer has caught a black hole eating a star, from the initial capture to the last bites.

Water Still Flows In Brief Spurts On Mars, NASA Images Suggest
NASA photographs have revealed bright new deposits seen in two gullies on Mars that suggest water carried sediment through them sometime during the past seven years.
So let the hunt for the ETs begin :)
