Targeting cancer with magnetic microcarrier – Nanomedicine | As a rule chemotherapy is like using a blunderbuss against cancer. ‘Chemo’ is administered through the bloodstream, which of course goes everywhere in the body. While the anti-cancer chemistry can be targeted to a certain extent, it almost always has toxic side effects with other organs and [...]

Update: Who’s afraid of Watson?
Not long ago a computer assembled by IBM, named Watson, whupped a couple of good-old-boys and all-time-winners at the game of Jeopardy! This garnered a good deal of attention, mainly with the notion that computers are becoming as smart as people. No, I said, in an essay titled “Who’s afraid of Watson?” [SciTechStory: Who’s afraid [...]

Stress test for computers: New sorting records
In the old days people used index cards to sort information such as names or addresses by alphabetical order. Have you ever sorted a thousand cards? Try sorting the information on 210 DVDs or 1,422 CDs – that’s how much information is contained in a terabyte (1000 gigabytes or one million megabytes). Obviously this is [...]

Concept news: A one-molecule transistor
Two scientists, Mark Reed, the Harold Hodgkinson Professor of Engineering & Applied Science at Yale (USA), and Takhee Lee, a former Yale postdoctoral associate and now a professor at the Gwangju Institute of Science and Technology (South Korea), have been working for more than a decade to show that a transistor (the fundamental electronic element [...]

A big step up: Two qubit computing
Step by step we’re moving closer to useful quantum computing. A big step, announced by the National Institute of Standards and Technology (NIST, USA), was the demonstration of a computing device using two qubits. Previous demonstrations by various researchers have used one qubit. In computing, two computational units are far more powerful than one. This [...]
IBM Cortical Simulator – more brain than a cat
Modeling brain function with a supercomputer is an ongoing scientific project, now spanning decades. Of course, as the computers become increasingly powerful, the results begin to look more realistic – and that creates a paradox…
