Kids with ADHD need to fidget, study says

May 27, 2009

Fidgeting helps kids with Attention-Deficit Hyperactivity Disorder focus by moving to maintain alertness, a University of Central Florida study has found.

Study leader Dr. Mark Rapport suspects they are “under-aroused” — that their brains do not produce enough dopamine to keep them alert during normal day-to-day activities — so the kids move around to jiggle or wake their brains and bodies up.

Synthetic proteins enable the growth of living cells

January 7, 2011

Novel proteins

In a groundbreaking achievement that could help scientists “build” new biological systems, Princeton University scientists have constructed for the first time artificial proteins that enable the growth of living cells.

The team of researchers created genetic sequences never before seen in nature, and the scientists showed that they can produce substances that sustain life in cells almost as readily as proteins produced by nature’s own toolkit.

Robot combined with swallowable camera could give docs a better look inside the small intestine

May 31, 2005

A Carnegie Mellon University engineer is developing a set of legs that could be incorporated into the swallowable camera-in-a-pill that has become available in the past four years for diagnosing gastrointestinal disorders in the small intestine.

The legs will form a tripod that could stop the capsule’s movement through the intestine, giving doctors a chance to take a closer look, or crawl as if it were an inchworm to… read more

Brain-controlled computer switches on in a heartbeat

January 10, 2008

Graz University of Technology scientists have developed a more effective on-switch for a brain-computer interface: voluntary spikes in the user’s heart rate.

Nano breakthrough charges science world

May 21, 2002

IBM researchers have created carbon nanotube field-effect transistors (CNFETs) that suggest that CNFETs may be competitive with Silicon MOSFETs for future nanoelectronic applications.
CNFETs deliver more than twice the amount of electrical current at a faster rate than silicon transistors. Increased current can lead to faster transistors and integrated circuits, so carbon may become a building block of computing in the future.

Endless original, copyright-free music

June 2, 2009

Inmamusys, an AI program that can create and play music in real time that evokes emotional responses, has been developed by University of Granada researchers.

Scorn over claim of teleported DNA

January 13, 2011

dnatransmission

Luc Montagnier, who shared the Nobel prize for medicine in 2008 for his part in establishing that HIV causes AIDS, says he has evidence that DNA can send spooky electromagnetic imprints of itself into distant cells and fluids. If that wasn’t heretical enough, he also suggests that enzymes can mistake the ghostly imprints for real DNA, and faithfully copy them to produce the real thing. In… read more

The Ethics of Creating Consciousness

June 14, 2005

Next month, IBM is set to activate the most ambitious simulation of a human brain yet conceived. It’s a model they say is accurate down to the molecule.

No one claims the “Blue Brain” project will be self-aware. But this project, and others like it, uses electrical patterns in a silicon brain to simulate the electrical patterns in the human brain — patterns which are intimately linked to thought.… read more

Graphene quantum dot may solve some quantum computing problems

January 16, 2008

Researchers at the Solid State Physics Laboratory in Zurich have proposed a method to use a tunable graphene quantum dot to create qubits (quantum bits).

A graphene-based qubit could solve some of the problems found in using gallium arsenide quantum dots in spin-based quantum computers.

Kurzweil to be featured on CBS ’48 Hours’ Friday night

June 14, 2002

Ray Kurzweil will be featured on CBS 48 Hours: “It’s All In Your Head” on Friday, June 14 at 10 p.m. ET/PT, discussing nanobots and other future scenarios.

Inflatable tower could climb to the edge of space

June 8, 2009

A giant inflatable 15-kilometer-high tower could carry people to the edge of space without the need for a rocket, and could be completed much sooner than a cable-based space elevator, its proponents claim.

If built from a suitable mountain top, it could reach an altitude of around 20 kilometers, where it could be used for atmospheric research, tourism (without the difficulties of zero gravity), telecoms, or launching spacecraft

Google’s free 3-D service brings views of Earth down to the PC

June 29, 2005

Google unveiled a free, three-dimensional satellite mapping technology Tuesday that is part flight simulator, part video game and part world atlas.

Google Earth allows users to zoom in from space, simulate flying above terrian or a city, get directions, find businesses and share the information with friends.

Google also introduced an updated version of its personalized search that personalizes results based on what a user has searched for… read more

Google to Host Terabytes of Open-Source Science Data

January 21, 2008

Google plans to host terabytes of open-source scientific datasets on research.google.com.

The storage will be free to scientists and access to the data will be free for all. Two planned datasets are all 120 terabytes of Hubble Space Telescope data and the images from the Archimedes Palimpsest, the 10th century manuscript that inspired the Google dataset storage project.

Small word network

July 5, 2002

Word association can link just about any two common (root) words in the English language using an average of three steps (degrees of separation), says a team of scientists at Arizona State University.
The researchers think the network structure of a language probably has its origins in the nature of cognition and memory. Different concepts, such as “actor” and “universe,” are closely linked by a short series of semantic… read more

‘Resurrection bug’ revived after 120,000 years

June 15, 2009

A tiny bacterium has been coaxed back to life after spending 120,000 years buried three kilometers deep in the Greenland ice sheet.

Researchers say it could resemble microbes that may have evolved in ice on other planets.
