From the discovery of the Higgs boson to the landing of the Curiosity rover on Mars, 2012 was an eventful year in science. Nature’s end of year round-up reviews the highs and lows in research and science policy.
Planktons constitute 98% of the ocean world and a group of researchers, after studying these in detail, believes that future oceanic changes would help in knowing which species of these would probably become extinct or migrate. Because these microscopic marine life forms, though very very small, contribute to the generation of oxygen on the planet…
Predicting the future is notoriously difficult, but uncovering the past can be just as tricky. Now researchers have developed a method that looks backward and may reveal where a widespread phenomenon originated, be it the outbreak of a disease or a new technology. The new method relies on distance, but is not constrained by geography….
At a time when obesity has become epidemic in American society, Dartmouth scientists have found that functional magnetic resonance imaging (fMRI) brain scans may be able to predict weight gain. In a study published in The Journal of Neuroscience, the researchers demonstrated a connection between fMRI brain responses to appetite-driven cues and future behavior. “This…
An ambitious plan to provide 15% of Europe’s power needs from solar plants in North Africa has run into trouble. The Desertec initiative hoped to deliver electricity from a network of renewable energy sources to Europe via cables under the sea. But in recent weeks, two big industrial backers have pulled out. And the Spanish…
Pygmy goats can develop “accents” as they grow older, according to scientists. The young animals, known as “kids”, are raised in groups or “creches” with goats of a similar age. Researchers found that when young goats mixed in these social groups their calls became more similar. The animals join an elite group of mammals known…
We could wring our hands about our unreconstructed nature but sex is at the center of human thought, and always has been. Some of the earliest cave art has erotic themes. We didn’t get where we are without genetic programming that makes us value eating, drinking and having sex. Add to that our inbuilt compulsion…
