In 1959, physicist and Nobel prizewinner Richard Feynman set scientists a goal of imaging to a resolution of 0.1 Angstrom - smaller than the radius of an atom. In 2013, researchers working in electron microscopy say we might not ever reach that goal, despite hitting 0.5 Angstroms a few years ago.... why? www.nature.com/...

Although discussed and feared for millennia, progress towards understanding epilepsy has been slow — even with help from modern genetic and neurological analysis. Stigmatization of people with epilepsy continues in certain parts of the world and though lack of funding limits epilepsy research, new ways to treat and manage seizures are on the horizon.

Should we set limits on what science can probe? Are some areas too questionable to investigate? Nature explores taboo genetics - the genetics of IQ, race, sexuality and violence - and the scientists that have crossed the red line to work on them. A poll asks if you think each of these areas should be off-limits to scientists... www.nature.com/... Nature Publishing Group
Nature Outlook Obesity: Rates of obesity continue to rise worldwide. About 65% of Americans are either overweight or obese, resulting in 300,000 excess deaths per year. Yet surprisingly little is known about the science which underpins this global epidemic. Why do some people seem predisposed to weight gain? And how does appetite actually work? Devising an effective strategy to combat obesity will require the integration of insights from neuroscience, genetics and the behavioural sciences.
