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.

Whole-Grain Cereals Reduce Heart Risks: Study

March 5, 2007

Eating whole-grain breakfast cereals seven or more times per week was associated with a lower (28 percent) risk of heart failure, according to an analysis of the observational Physicians’ Health Study.

Researchers presented findings of the study at the American Heart Association’s 47th Annual Conference on Cardiovascular Disease Epidemiology and Prevention. The study is supported by grants from the National Cancer Institute and the National Heart, Lung,… read more

Whole-genome sequences of supercentenarians reveal longevity clues

April 11, 2012

genome_supercentenarians

A team of researchers has analyzed the complete genomic sequences of male and female supercentenarians, both over 114 years old.

Surprisingly, the researchers showed that the DNA sequences are largely comparable to existing non-supercentenarian genomes, and the two individuals do not appear to carry most of the well-established human longevity-enabling variants already reported in the literature.

In fact, the supercentenarians have a comparable number of known disease-associated variants relative to… read more

Whole-genome sequences of 17 of the world’s oldest living people published

Researchers unable to find genes significantly associated with extreme longevity
November 13, 2014

Misao Okawa, the world's oldest living person

Using 17 genomes, researchers were unable to find rare protein-altering variants significantly associated with extreme longevity, according to a study published November 12, 2014 in the open-access journal PLOS ONE by Hinco Gierman from Stanford University and colleagues.

Supercentenarians are the world’s oldest people, living beyond 110 years of age. Seventy-four are alive worldwide; 22 live in the U.S. The authors of this study performed whole-genome sequencing on 17 supercentenarians to… read more

Whole-cell computer simulation

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, 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?

the_sims

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?

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?

March 26, 2013

(Credit: World Life Expectancy)

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
