Whole-cell computer simulation

April 1, 2011

Sugar Protein

Researchers at the Max Planck Institute of Biology in Germany and theoretical scientists at the University of Illinois have built a computer model of a bacterial cell that responds to sugar in its environment and accurately simulates the behavior of living cells.

Running simulations on models of two E. coli strains, the researchers were able to see that bacterial cell architecture affects the reactions… read more

Whole-Body Gaming

(Softkinetic)

Softkinetic, based in Belgium, is working to let video-game players use a wider range of more-natural movements to control the on-screen action.

Its software is meant to work with depth-sensing cameras, which can be used to determine a player’s body position and motions.

Whole brain cellular-level activity mapping once a second

Neuroscientists at Howard Hughes Medical Institute have mapped the activity of nearly all the neurons in a vertebrate brain at cellular resolution, with signficant implications for neuroscience research and projects like the proposed Brain Activity Map (BAM).

The researchers used high-speed light sheet microscopy to image the activity of 80% of the neurons in the brain (which is composed of ~100,000 neurons) of a fish… read more

Whole Body Muscle Gene Therapy Progress

November 3, 2008

University of Missouri researchers have found a delivery method for gene therapy that can reach every muscle of the body in large animals and could eventually cure human diseases like muscular dystrophy.

Whole body muscle gene therapy could also create the ultimate in human running speed and strength.

Whoa, dude, are we inside a computer right now?

Two years ago, Rich Terrile appeared on Through the Wormhole, the Science Channel’s show about the mysteries of life and the universe. He was invited onto the program to discuss the theory that the human experience can be boiled down to something like an incredibly advanced, metaphysical version of The Sims, Vice reports.

It’s an idea that every college student with a gravity bong and The Matrix… read more

Who should explore space, man or machine?

February 20, 2003

A contest for dominance in space pits biology and brains against circuits and chips.

Who Says Science Can’t Be Fun?

January 17, 2003

Commercial applications have come from the fertile imagination of MIT Media Lab researchers, such as composer Tod Machover, whose Etch-A-Sketch-like device lets children compose by drawing lines on a computer screen and is due to be released as a toy.

WHO Promises H1N1 Swine Flu Vaccine for All

May 7, 2009

If there’s an H1N1 swine flu pandemic, vaccine makers should be able to churn out “at least” 1 billion to 2 billion doses of H1N1 swine flu vaccine within four to six months, the World Health Organization (WHO) estimates.

As of May 6, there were 1893 confirmed cases in 23 countries, including 642 cases in 44 states in the U.S.

Who Needs Hackers?

September 12, 2007

Problems arising from flawed systems, increasingly complex networks and even technology headaches from corporate mergers can make computer systems less reliable.

Meanwhile, society as a whole is growing ever more dependent on computers and computer networks, as automated controls become the norm for air traffic, pipelines, dams, the electrical grid and more.

“We don’t need hackers to break the systems because they’re falling apart by themselves,” said Peter… read more

Who lives longest?

Life expectancy is an average, and it fluctuates with age as the risks we face change throughout our lifetimes. Both those facts make it a frequently misunderstood statistic, The New York Times reports.

High infant-mortality rates depress the figure substantially. This can lead contemporary observers to the false conclusion that most humans died quite young, even in the not-so-distant past.

Before the Upper Paleolithic, early humans really… read more

Who is messing with your head?

“For the first time, we were able to link the auditory signal in the brain to what a person said they heard when what they actually heard was something different. We found… read more

WHO declares swine flu pandemic

June 12, 2009

The World Health Organization (WHO) has declared a global flu pandemic, meaning the swine flu virus is spreading in at least two regions of the world.

It has spread to 74 countries. It is the first flu pandemic in 40 years; the last in 1968 killed about one million people. However, the current pandemic seems to be moderate and causing mild illness in most people.

White roofs, streets could curb global warming

September 18, 2008

If the 100 largest cities in the world replaced their dark roofs with white shingles and their asphalt-based roads with concrete or other light-colored material, it could offset 44 metric gigatons (billion tons) of greenhouse gases, a study by Lawrence Berkeley National Laboratory and UC Berkeley shows.

White surfaces would also lower the cost of air conditioning by up to 20% in hot months and cool a city by… read more
