Moore's Law Maintained by 3D Computer Chip

Despite predictions to the contrary, Intel has developed a new computer chip which fits more transistors into a smaller space. Computer power is still looking set to increase into the future. 

What's the Latest Development?


Intel has created a commercial computer chip which runs 37% faster than previous chips and matches their processing power using half the energy. Called Ivy Bridge, the chip maintains a trend known as Moore's Law which has predicted the doubling of computer power every two years, achieved by the doubling of transistors, since 1975. "Transistors on an Ivy Bridge processor are packed roughly twice as densely as in the most recent line of Intel chips, with 1.4 billion on a 160 square millimeter die instead of 1.16 billion on a 212 square millimeter die." Features on the chip are as small as 22 nanometers across. 

What's the Big Idea?

To maintain Moore's Law, Intel had to substantially redesign the transistor, the tiny electronic switches that make up a computer chip. Previously, packing transistors into a tighter arrangement caused them to leak, meaning the chip would overheat. This led many to predict to the end of Moore's Law and the end of consumers' expectations for ever-faster computing. "Intel got around that by adding an extra dimension to transistors, which for decades have been made as a stack of flat layers of material on top of one another." The company is already at work on a chip with smaller features, scheduled for production by 2014.

Surprising Science
  • China's Chang'e 4 lunar lander touched down on the far side of the moon on January 3.
  • In addition to a lunar rover, the lander carried a biosphere experiment that contains five sets of plants and some insects.
  • The experiment is designed to test how astronauts might someday grow plants in space to sustain long-term settlements.

A world map of Virgin Mary apparitions

She met mere mortals with and without the Vatican's approval.

Strange Maps
  • For centuries, the Virgin Mary has appeared to the faithful, requesting devotion and promising comfort.
  • These maps show the geography of Marian apparitions – the handful approved by the Vatican, and many others.
  • Historically, Europe is where most apparitions have been reported, but the U.S. is pretty fertile ground too.

Love in a time of migrants: on rethinking arranged marriages

Arranged marriages and Western romantic practices have more in common than we might think.

Culture & Religion

In his book In Praise of Love (2009), the French communist philosopher Alain Badiou attacks the notion of 'risk-free love', which he sees written in the commercial language of dating services that promise their customers 'love, without falling in love'.
