Some companies have developed a newer type of animation that requires less processing power.

Virtual Worlds May Be the Future Setting of Scientific Collaboration

August 5, 2009

The first professional scientific organization based entirely in virtual worlds, the Meta Institute for Computational Astrophysics (MICA), has been formed by scientists from the California Institute of Technology, Princeton, Drexel University, and MIT.

In addition to getting people together in a free and convenient way, virtual worlds can offer new possibilities for multi-dimensional data visualization.

Researchers find key step in programmed cell death

March 3, 2008

St. Jude Children’s Research Hospital researchers have discovered three molecules that together protect certain cells from undergoing apoptosis–programmed cell death–describing one mechanism for how cells may delay apoptosis.

Molecular malfunctions that trigger apoptosis may cause some diseases, including Parkinson’s disease.

Library of Congress Plans World Digital Library

November 22, 2005

The U.S. Library of Congress is kicking off a campaign on Tuesday to work with other nation’s libraries to build a World Digital Library, starting with a $3 million donation from Google Inc.

Over the past decade, the American Memory Project of the Library of Congress has digitized more than ten million items to create a documentary record of Americana.

These include manuscripts, maps, audiovisual recordings,… read more

First Results From The Allen Telescope Array

August 13, 2009

The Allen Telescope Array, a joint operation between the SETI Institute in Mountain View and the University of California, Berkeley, has imaged the movement of atomic hydrogen clouds in the intergalactic space between nearby galaxies, which could help solve one of the big mysteries of star formation.

Turning Glare Into Watts

March 6, 2008
(Isaac Brekke/The New York Times)

As prices rise for fossil fuels and worries grow about their contribution to global warming, solar thermal plants are being viewed as a renewable power source with huge potential.

The technology involves covering acres of desert with mirrors that focus intense sunlight on a fluid, heating it enough to make steam. The steam turns a turbine and generates electricity. Some experts say that solar thermal plants could… read more

Why this brain flies on rat cunning

December 7, 2005

A “brain” grown from 25,000 neural cells extracted from a single rat embryo has been taught to fly an F-22 jet simulator by scientists at the University of Florida.

They hope their research into neural computation will help develop sophisticated hybrid computers with a thinking biological component. The first result could be to enable scientists to enabling more flexible and varied means of solving problems.

CONSCIOUSNESS AND THE BRAIN

February 11, 2003

Nobel laureate Francis Crick and and neuroscientist Christof Koch outline a strategy to develop a coherent scheme for determining the neural correlates of consciousness in philosophical, psychological and neural terms in the February issue of Nature Neuroscience.

Their approach centers on the visual system of primates, drawing on data from electrical recordings in awake monkeys, behavioral studies in humans and the effects of specific brain damage. Much of the… read more

Video appears in paper magazines

August 21, 2009

The first video-in-print ads, using chips and thin screens around the size of mobile phone displays, will appear in select copies of Entertainment Weekly magazine in September and hold 40 minutes of video.

The first clips will be promos for CBS programs and Pepsi.

Testing Over, Hulu.com to Open Its TV and Film Offerings This Week

March 11, 2008

Hulu.com will make its catalog of TV shows and video clips available to anyone on the Web starting Wednesday.

The streaming-video site displays free, ad-supported shows and feature films from NBC, Fox and more than 50 media companies, including Sony Pictures and Metro-Goldwyn-Mayer.

Stems cells as drug delivery carriers to the brain

December 15, 2005

Engineered human brain progenitor cells, transplanted into the brains of rats and monkeys, can effectively integrate into the brain and deliver medicine where it is needed, bypassing the blood-brain barrier, University of Wisconsin-Madison researchers have found.

The Wisconsin team obtained and grew large numbers of progenitor cells from human fetal brain tissue. They then engineered the cells to produce a growth factor known as glial cell line-derived neurotrophic factor… read more

Stressed-DNA repair protein identified

June 17, 2011

Vera Gorbunova and Andrei Seluanov of the University of Rochester have found that human cells undergoing oxidative stress caused by environmental chemicals or routine cellular processes produce a protein (SIRT6) that stimulates cells to repair DNA double-strand breaks, thought to be associated with premature aging and cancer.

The team first measured levels of SIRT6 in stressed cells, then treated a second… read more

New Molecular Self-Assembly Technique May Mimic How Cells Assemble Themselves

February 26, 2003

Researchers have created tree-like molecules that assemble themselves into precisely structured building blocks of a quarter-million atoms. Such building blocks may be precursors to designing nanostructures for molecular electronics or photonics materials, which “steer” light in the same way computer chips steer electrons.

Where Have You Gone, Bell Labs?

August 31, 2009

The root of the current lack of new, high-quality job creation is the massive scaling back of science and engineering research, which has in the past made enormous contributions to science, technology, and the economy, including the creation of millions of high-paying jobs, says management consultant Adrian Slywotzky.

Here’s what’s needed to get that model back on track, he suggests:

• Clear national goals in two or three… read more
