cells make mini lab

|
Split an artificial cell in half and you get
not only two new artificial cells but a nanotube
connecting them. Swedish researchers have
built networks of microscopic containers and
tubes and moved a particle from one container
to another. The result could be entire chemistry
labs that are invisible to the naked eye.

PDA
interface keeps a low profile
Handheld computer interfaces are a lot like that museum guide who keeps blocking your view. An interface developed at Xerox PARC promises to offer help only when you need it.
Software
sifts text to sort Web sites
Search engines do a decent job of finding words in millions of web pages but they're generally clueless about the sites they search. Researchers are aiming to give them a shot at being able to separate, for instance, the medical from the pornographic.
Light
drives microscopic metal gears
Shining lasers on certain microscopic particles suspended in liquid turns them into tiny whirling dervishes. Researchers in Australia have harnessed the resulting waves to spin metal gears.
Quantum
computer design lights dots
Before anyone can crank out quantum computer chips,
researchers need to get the most out of quantum
bits that exist for only fractions of a second.
A team of Italian researchers is looking at hitting
tiny specks of semiconductor with ultrafast laser
pulses as the answer.
