A Camera That Peers Around Corners
From ACM TechNews

A Camera That Peers Around Corners

Massachusetts Institute of Technology researchers have developed a system that can produce recognizable three-dimensional images of objects located around corners...

Tiny 3D Chips
From ACM News

Tiny 3D Chips

Microelectromechanical systems, or MEMS, are small devices with huge potential. Typically made of components less than 100 microns in size—the diameter of a human...

Microchips' Optical Future
From ACM News

Microchips' Optical Future

To keep energy consumption under control, future chips may need to move data using light instead of electricity—and the technical expertise to build them may reside...

New System Allows Robots to Continuously Map Their Environment

MIT researchers have developed a system that enables robots to create and continuously update a three-dimensional map of their environment using a low-cost camera...

Robots in Reality
From ACM News

Robots in Reality

Consider the following scenario: A scout surveys a high-rise building that's been crippled by an earthquake, trapping workers inside. After looking for a point...

Important Step Toward Computing with Light
From ACM News

Important Step Toward Computing with Light

There has been enormous progress in recent years toward the development of photonic chips—devices that use light beams instead of electrons to carry out their...

Printing Off the Paper
From ACM News

Printing Off the Paper

Imagine being able to "print" an entire house. Or a four-course dinner. Or a complete mechanical device such as a cuckoo clock, fully assembled and ready to run...

Increasing Fuel Efficiency With a Smartphone
From ACM TechNews

Increasing Fuel Efficiency With a Smartphone

Researchers at MIT and Princeton University have developed SignalGuru, a system that uses a network of smartphones mounted on a car dashboard to collect information...

From ACM News

A New Planning Tool Helps Direct Traffic on Aircraft Carriers

On the deck of an aircraft carrier, where up to 60 aircraft are crammed into 4.5 acres (1.8 hectares), real estate is at a premium. While aircraft directors wave...

Layer ­pon Layer
From ACM News

Layer ­pon Layer

Graphene, a form of pure carbon arranged in a lattice just one atom thick, has interested countless researchers with its unique strength and its electrical and...

Streamlined Rules For Robots
From ACM News

Streamlined Rules For Robots

With the explosion of the Internet and the commoditization of autonomous robots (such as the Roomba) and small sensors (such as the ones in most cell phones),...

Long Live the Qubit!
From ACM News

Long Live the Qubit!

A quantum computer is a device—still largely theoretical—that could perform some types of calculations much more rapidly than classical computers. While a bit...

Which Technologies Get Better Faster?
From ACM TechNews

Which Technologies Get Better Faster?

Massachusetts Institute of Technology researchers have developed a mathematical model to predict which technologies are the most likely to rapidly advance and be...

Toward Faster Transistors
From ACM News

Toward Faster Transistors

In the 1980s and '90s, competition in the computer industry was all about "clock speed"—how many megahertz, and ultimately gigahertz, a chip could boast. But...

From ACM News

Kaashoek Wins Acm's Prize For Young Researchers

Frans Kaashoek, a professor in the MIT Department of Electrical Engineering and Computer Science and associate director of the Computer Science and Artificial...

The Quantum Singularity
From ACM TechNews

The Quantum Singularity

MIT professor Scott Aaronson and grad student Alex Arkhipov will present a paper at ACM's 43rd Symposium on Theory of Computing that describes an experiment, which...

Retooling Algorithms
From ACM News

Retooling Algorithms

Charles Leiserson and his team are experts at designing parallel algorithms—including one for a chess-playing program that outperformed IBM’s Deep Blue.

From ACM News

Multicore May Not Be So Scary

Research suggests that the free operating system Linux will keep up with the addition of more "cores," or processing units, to computer chips.

An Internet 100 Times As Fast
From ACM News

An Internet 100 Times As Fast

A new network design that avoids the need to convert optical signals into electrical ones could boost capacity while reducing power consumption.

Computing, Sudoku-Style
From ACM News

Computing, Sudoku-Style

Though still in its infancy, the work of Alexey Radul as a postdoc at MIT could someday have consequences for artificial-intelligence research, parallel computing...
