MEMORY ENGINEERS

Memory engineersEver wish you could forget an embarrassing or painful memory? Soon you might be able to. Also in this issue: a 26-page Darwin Special, which traces all the latest insights in evolution: from genetics to the bizarre solutions for genitalia and sex. Plus, we look at the coming revolution electric cars will bring to every aspect of your life; we take a close-up look in stunning colour at the parasites living inside us; and we show you where comets really come from.

DARWIN'S LAST JOURNEY

DARWIN'S LAST JOURNEY

When Charles Darwin proposed his grandiose theory of evolution 150 years ago in November, the heated controversy flared for decades. But, as Iain McCalman recounts, by the time he died 23 years later, the battle was over – and Darwin had won.

CHILDREN OF EVOLUTION

CHILDREN OF EVOLUTION

Evolution is an elegant and powerful way to describe life. But it doesn’t explain everything, Rachel Ehrenberg writes, and it takes advances in genetics and molecular science to give us even deeper insights.

MISSING LINKS

MISSING LINKS

Transitional fossils are the hardest to find, but sometimes tell the best stories, as Sid Perkins discovers when he sets out to find fossil hunters who are mining the gaps.

DANGEROUS LIASONS

DANGEROUS LIASONS

From maze-like genitalia and terrifying spikes to ornamental handicaps and disloyal mothers, evolution seems to have found some seriously stupid designs for sex, finds Susan Milius.


THE ELECTRIC REVOLUTION

THE ELECTRIC REVOLUTION

Your next car will likely be an electric vehicle. Tim Thwaites looks at the rapidly developing technologies that will see the motoring world we’ve known turned on its head – and help cities store renewable energy to boot.

LEARNING TO FORGET

LEARNING TO FORGET

Can science delete painful memories that cause distress with drugs and treatment? A barrage of recent studies suggest memories can be manipulated, downplayed and even made to disappear, as Emma Young reports.
