Intel sampling first ICs made on 90-nm line

September 4, 2003

Intel Corp. is sampling the first microprocessors manufactured on its 90-nanometer process technology — the Prescott for desktop PCs and the Dothan, an improved version of the Pentium M chip for laptops.

Prescott, an upgrade over current Pentium 4 microprocessors, doubles the on-die Level 2 cache to 1 Mbyte with an expected 3.4-GHz frequency.

Building a Search Engine of the Brain, Slice by Slice

December 28, 2009

A “Google Earthlike search engine,” the first entirely reconstructed, whole-brain atlas with resolution all the way down to the level of single cells–2.5 petabytes of information– will be available at the Brain Observatory at U.C. San Diego to anyone who wants to log on.

Access to next-gen Internet may be uneven

May 23, 2008

Graham Finnie, chief analyst for the telecom research firm Heavy Reading, believes 13 percent of U.S. households will be connected to fiber by 2012. Since Verizon is the major builder, the vast majority of those will be in Verizon territory on the East Coast, Texas and California.

“A quarter of the U.S. is going to get one of the best networks in the world,” said Dave Burstein, editor of… read more

Meet the Remote-Control Self

July 21, 2006

Hiroshi Ishiguro, a senior researcher at ATR Intelligent Robotics and Communication Laboratories outside Kyoto, has created a machine in his own image — a robot that looks and moves exactly like him. It sits on a chair and gazes around the room in a very humanlike fashion, just like its creator.

Invisibility tiles can cloak any shape

October 27, 2011

Invisibility tiles

Oliver Paul at the University of Kaiserslautern in Germany and associates have revealed a practical way of making invisibility cloaks of any size and shape, The Physics ArXiv Blog reports.

Creating a cloak that exactly follows the shape of the object it is intended to hide is hard because curve cloaks are hard to make, so they approximated the shape using flat facets.

Ban cloning babies, demand world’s top scientists

September 23, 2003

Cloning babies should be banned worldwide by the United Nations, more than 60 of the world’s leading scientific academies demanded on Monday.

But the ban should not extend to therapeutic cloning, they added.

Where Did the Time Go? Do Not Ask the Brain

January 5, 2010

New research suggests why time seems to speed up or slow down.

In experiments, psychologists found that subjects underestimated how much time had passed by three months, but the more intervening related developments came to mind, the longer away the original event seemed.

They also found that when people were tricked into believing that more time had passed than was really the case, they assumed they must have… read more

Fruits, vegetables and teas may protect smokers from lung cancer

May 30, 2008

UCLA cancer researchers have found that smokers who ingested high levels of natural chemicals called flavonoids in their diet (from fruits, vegetables and tea) had a lower risk of developing lung cancer than other smokers.

Flavonoids are water-soluble plant pigments that have antioxidant and anti-inflammatory properties, both of which can counteract damage to tissues.

The flavonoids that appeared to be the most protective included catechin (strawberries and green… read more

Sensory illusions dazzle at graphics conference

August 3, 2006

Inventions on display at the SIGGRAPH 2006 computer graphics conference, which opened in Boston, on Monday,
include a toy house that appears to warp into surreal shapes, a handheld device that “pulls” a person around, and a display that generates holographic illusions using scores of hidden projectors.

Worldwide bacteria network may readily swap beneficial genes

November 3, 2011


MIT researchers have found evidence of a massive network connecting bacteria from around the world: 10,000 unique genes flowing via horizontal gene transfer (HGT) among 2,235 bacterial genomes.

HGT is an ancient method for bacteria from different lineages to acquire and share useful genetic information they didn’t inherit from their parents. The MIT team’s work illustrates the vast scale and rapid speed with which genes can proliferate… read more

Shooting for Space

October 7, 2003

Cisco and its partners, including NASA, have launched a router into low Earth orbit as a test of extending the Internet into space.

Space-based routers could be used to tie the military’s myriad networks together and the government’s research networks together so that personnel on land, in the air or at sea can communicate directly.

Cisco also sees private-sector enterprise and consumer applications.

Chemical computer that mimics neurons to be created

January 12, 2010

A new biologically inspired “wet computer” research project uses chemical reactions to mimic neurons.

Funded by an EU emerging technologies program, it will make use of stable “cells” featuring a coating that forms spontaneously, similar to the walls of our own cells, and uses chemistry to accomplish the signal processing similar to that of our own neurons.

It is intended for uses such as controlling molecular robots, fine-grained… read more

Inflatable electric car can drive off cliffs

June 5, 2008

The company XP Vehicles plans to sell inflatable cars made with “airbags”–the same polymer materials used to cushion NASA’s rovers when they landed on Mars.

Different models of the car will be made of various polymers, carbon fiber, and other strong, ultra-light-weight materials. They claim its low weight will allow it to have a range of 300 to 2,500 miles per charge, depending on what battery technology is in… read more

‘Electron-spin’ trick boosts quantum computing

August 18, 2006

A new silicon chip capable of manipulating the spin of a single electron could ultimately allow futuristic quantum computers to be built using conventional electronic technology.

How Occupy Wall Street occupied Twitter, too

November 10, 2011


Thanks to a start-up called SocialFlow, we can see how Occupy Wall Street propagated through influential people and organizations, and across previously invisible conduits to permeate vast expanses of Twitter’s network, Technology Review Editors reports.
