Breathing life into messy sketches

October 14, 2003

AI-based software being developed by the Artificial Intelligence Laboratory at MIT will observes what we draw on the screen and then turns the sketch into computer code.

The smart program is able to interpret what we had in mind from the crude drawing, then animates the sketch by applying the laws of physics to create motion using gravity and momentum — balls roll down slopes, a propeller creates lift.

Citizens strike back in intelligence war

October 14, 2003

Government Information Awareness (GIA), a website to be launched later in 2003, will allow people to post information about the activities of government organizations and officials.

To protect against legal action if postings are false, the two MIT researchers behind the project plan to use a peer-to-peer network with data stored in a number of locations around the Internet.

Neuroscience Networks: Data-sharing in an Information Age

October 13, 2003

The current challenge in brain mapping is data sharing and integrating information into a coherent, accessible form that permits hierarchical analysis from RNA to protein to morphology to connectivity to experimental behavioral and clinical sciences.

Efforts driven by collaboration, coordination, and computation should yield the data, tools, and resources that neuroscientists will need in the coming decades. New electronic publications [such as PLoS Biology, launched today, and free to… read more

Purdue researchers stretch DNA on chip, lay track for future computers

October 10, 2003

Researchers have precisely placed strands of DNA on a silicon chip and then stretched out the strands so that their encoded information might be read more clearly, two steps critical to possibly using DNA for future electronic devices and computers.

Join the dots

October 10, 2003

A network of quantum dots that pass electrons between them one at a time can be used to carry out logic operations at very high device integration densities.

Cosmic Soccer Ball? Theory Already Takes Sharp Kicks

October 10, 2003

The just-announced model of the universe as a kind of 12-sided hall of mirrors, in which the illusion of infinity is created by looking out and seeing multiple copies of the same stars, has already been disproven, say some scientists.

Free science journal hits press

October 10, 2003

The Public Library of Science has launched a free magazine for scientists, PLoS Biology.

The magazine charges researchers $1,500 to publish a paper, rather than readers.

What’s wrong with the electric grid?

October 10, 2003

Experts widely agree that failures of the power-transmission system such as the recent Northeast United States blackout are a nearly unavoidable product of a collision between the physics of the system and the economic rules that now regulate it.

To avoid future incidents, the nation must either physically transform the system to accommodate the new rules, or change the rules to better mesh with the power grid’s physical behavior.

Tantalising evidence hints Universe is finite

October 9, 2003

Scientists have announced hints that the Universe is actually relatively small — something like 70 billion light years across — with a hall-of-mirrors illusion tricking us into thinking that space stretches on forever.

The thinking is based on observations by NASA’s Wilkinson Microwave Anisotropy Probe (WMAP), which measures temperature ripples in the cosmic microwave background.

Our Universe seems like an endlessly repeating set of dodecahedrons (12 identical pentagons)… read more

GM ‘could be another Thalidomide’

October 9, 2003

Plans for the future of GM crops in Britain suffered a massive blow as insurance giants issued dire warnings about the unknown dangers posed by the supercrops.

Insurance firms are refusing to offer cover to farmers who want to plant GM crops because they fear a public health disaster and huge compensation payouts.

AAA Battery Gets a Mini-Me

October 9, 2003

The smallest implantable battery in the world may soon be powering bionic neurons. The small size allows doctors to use minimally invasive techniques when implanting the bionic neurons, reducing surgical trauma and the risk of infection.

Recharging is done wirelessly by an external electrical field, so implants no longer have to be surgically removed and replaced.

The battery may power implantables for stroke victims and people suffering from… read more

Who’s Afraid of Nanotechnology

October 8, 2003

The ability to construct molecule-size objects holds both promise and peril. Some nanotech scientists and business people fear a backlash such as the one that has stalled acceptance of genetically modified foods.

Is Life the Key to New Tech?

October 8, 2003

DNA computing has the potential to perform trillions of calculations at once and the size and the ease of interfacing with living material may make them ideal for use in medicine. But bio-molecular computers must await a breakthrough in designer enzymes.

Smart Cards Track Commuters

October 8, 2003

Civil rights campaigners have expressed concerns about new smart travelcards that track a London commuter’s movements and store them in a database.

Tumor-Busting Viruses

October 8, 2003

“Smart” virotherapy — better ways of genetically engineering viruses that selectively infect and kill cells — may play an important role in the future of combating cancer.
