In TR’s special issue on the future of computing (Beyond Silicon, TR May/June 2000), we documented efforts to replace silicon with computers based on quantum effects, DNA and organic molecules. Advances reported in each of these areas in August have brought the technologies closer to reality.
A collaboration led by IBM Research’s Isaac Chuang (one of the TR100) created an advanced quantum computer that was able to solve in one step a mathematical problem that requires repeated steps in a conventional computer.
Chemists at the University of California, Los Angeles made an on/off switch using an organic molecule and predict they will soon have working memory for the molecular computer they are building with researchers at Hewlett-Packard.
Scientists at Lucent Technologies’ Bell Labs and Oxford University reported in the journal Nature that they had built a minuscule motor out of DNA, work that could one day lead to the nanofabrication of functioning
How SpaceX’s massive Starship rocket might unlock the solar system—and beyond
With the first orbital test launch of Starship on the horizon, scientists are dreaming about what it might make possible— from trips to Neptune to planetary defense.
The therapists using AI to make therapy better
Researchers are learning more about how therapy works by examining the language therapists use with clients. It could lead to more people getting better, and staying better.
The US crackdown on Chinese economic espionage is a mess. We have the data to show it.
The US government’s China Initiative sought to protect national security. In the most comprehensive analysis of cases to date, MIT Technology Review reveals how far it has strayed from its goals.
A horrifying new AI app swaps women into porn videos with a click
Deepfake researchers have long feared the day this would arrive.
