Want to influence the world? Map reveals the best languages to speak
Speak or write in English, and the world will hear you. Speak or write in Tamil or Portuguese, and you may have a harder time getting your message out. Now, a new method for mapping how information flows around the globe identifies the best languages to spread your ideas far and wide. One hint: If you’re considering a second language, try Spanish instead of Chinese.

Colour to dye for
The basic chemistry of hair dyes has changed little over the last century, but what do we know about the risks of colouring our hair, and why do we do it?
When it comes to DNA, crocodiles and birds flock together
If you really want to know about birds, you have to consider the crocodile.
That point was driven home this week with the release of the genomes of 45 bird species,which reassigned some perches on the avian evolutionary tree and included some seemingly odd bedfellows.
La extraña asimetría de las moléculas quirales podría estar relacionada con el magnetismo
Un trabajo internacional liderado por la Universidad Autónoma de Madrid e IMDEA-Nanociencia aporta resultados experimentales que apoyan la teoría de una relación entre quiralidad molecular y magnetismo. La quiralidad es una propiedad que tienen algunos objetos de no ser superponibles con su imagen especular.

An Evolutionary Battle Against Bacteria
Every disease has a history. Some of that history is written in books, and some is written in our DNA.
Tropical forests may not combat climate change
Tropical forests may not save us from global warming. Scientists have long believed that as atmospheric carbon dioxide rises, the greenhouse gas could boost photosynthesis, enabling tropical and other forests to take up more carbon and store it as wood. Some data suggest this “carbon fertilization” effect is already happening, and many climate models assume it will help slow the rise in CO2. But a new analysis of tree ring samples collected in Bolivia, Cameroon, and Thailand finds no sign of increasing growth over the past 150 years.
