However, University of North Carolina at Chapel Hill physics Professor Laura Mersini-Houghton made a staggering claim. She says, “Standard cosmology cannot explain such a giant cosmic hole” and goes further with the ground-breaking hypothesis that the huge void is “… the unmistakable imprint of another universe beyond the edge of our own“..."

The sun remains by far the most massive object in the solar system, with an extended influence of particles that reaches all the planets. But the comparatively tiny Comet Holmes has released so much gas and dust that its extended atmosphere, or coma, is larger than the diameter of the sun. The comparison is clear in a new image..."

"Could people one day evolve to eat rich food while remaining perfectly slim and svelte?
This may not be so wild a fantasy. It is becoming clear that the human genome does respond to changes in diet, even though it takes many generations to do so.
Researchers studying the enzyme that converts starch to simple sugars like glucose have found that people living in countries with a high-starch diet produce considerably more of the enzyme than people who eat a low-starch diet.The reason is an evolutionary one..."

BONN, Germany, July 6 (UPI) -- German researchers say their discovery that the Earth is smaller than originally thought may have serious ramifications for climate change.
The difference is minute -- all of five millimeters -- but that is crucial to studying how climate changes the Earth, said researchers at Bonn University.
Five millimeters (0.2 inches) is less than half the width of an average finger, which may seem negligible in comparison to the earth's diameter of 7,926.3812 miles."

University of Wisconsin-Madison researchers said last week they have found a better way of converting fructose, a common sugar, into a fuel called 2,5-dimethylfuran, or DMF.
The biofuel has a higher energy content than ethanol, the only renewable liquid fuel currently produced on a large scale. It also doesn't absorb water from the atmosphere, a shortcoming of ethanol, said James Dumesic, one of the researchers and a professor of chemical and biological engineering at the university."

Fossilized bones uncovered in the Erlian Basin of northern China's Inner Mongolia region show that the specimen was about 26 feet long, 16 feet tall and weighed 3,000 pounds, said Xu Xing, a paleontologist at the Institute of Vertebrate Paleontology & Paleoanthropology in Beijing.
The height is comparable to the meat-eating tyrannosaurs. But the dinosaur, called Gigantoraptor erlianensis, also had a beak and slender legs and likely had feathers. It was 35 times larger than its likely close relation, the Caudiperyx, a small, feathered dinosaur species, Xu said.
That puts the Gigantoraptor's existence at odds with prevailing theories that dinosaurs became smaller as they evolved into birds and that bigger dinosaurs had less birdlike characteristics, he said..."

InformationWeek Weblog: The Year 2000 As Predicted In 1900: Did They Anticipate Wireless Phones And TV?
It is always interesting to see what people in the past thought "the future" would be like. Predictions usually say more about the people in the age they were made than they do about the future. But sometimes, a few of these predictions really hit home.
I came across this article from The Ladies Home Journal of December 1900 entitled, "Predictions of the Year 2000" on Andrew Sullivan's blog. While most of these predictions seem totally out of date, more than a few are not that off the mark. Take this one, for example:
Prediction #18: Telephones Around the World. Wireless telephone and
telegraph circuits will span the world. A husband in the middle of the Atlantic
will be able to converse with his wife sitting in her boudoir in Chicago. We
will be able to telephone to China quite as readily as we now talk from New York
to Brooklyn. By an automatic signal they will connect with any circuit in their
locality without the intervention of a "hello girl".

DURHAM, N.H. -- Holding eye contact, or 'gaze,' with hysterical citizens is one of the most effective methods police officers can use to calm them down, according to new research conducted by the University of New Hampshire that relies on footage of the FOX TV show 'COPS.'
The study by Mardi Kidwell, assistant professor of communication, '�Calm Down!�: the role of gaze in the interactional management of hysteria by the police,' was published recently in Discourse Studies.
According to Kidwell�s research, regulating gaze is central to face-to-face interaction. For police officers, it�s an important factor in gaining compliance from and calming hysterical citizens..."

Artificial DNA with encoded information can be added to the genome of common bacteria, thus preserving the data. The technique was developed at Keio University Institute for Advanced Biosciences and Keio University Shonan Fujisawa Campus. If you think those USB flash memory 'thumbdrives' are small, check this data storage out.
According to researchers, up to 100 bits of data can be attached to each organism. Scientists successfully encoded and attached the phrase 'e=mc2 1905' to the DNA of bacillus subtilis, a common soil bacteria.
One early use for the technique would be to create special markers to identify legitimate versions of pharmaceuticals. However, the bacillus itself creates new copies of the data every time it reproduces itself, thus making it an ideal archival storage system..."

...The development means the fundamental 'law' that underpins the development of all microchips, known as Moore's Law, remains intact.
The proposition, articulated by Intel co-founder Gordon Moore in 1965, states that the number of transistors on a chip could double every 24 months.
After more than 10 years of effort, we now have a way forward
Tze-chiang Chen, IBM
The new Intel processors, codenamed Penryn, will pack more than four hundred million transistors into a chip half the size of a postage stamp.
Like current processors, they will come in dual-core and quad-core versions, meaning they will have two or four separate processors on each chip. The company has not said how fast the new devices will run.
The production of 45nm technology has been the goal of chip manufacturers ever since they conquered 65nm transistors..."

Earth's Moon Destined to Disintegrate
Special to SPACE.com
SPACE.com Mon Jan 22, 10:15 AM ET
The Sun is midway through its stable hydrogen burning phase known as the main sequence. But when the Sun enters the red giant phase in around 5 billion years things are going to get a lot rougher in the Earth-Moon system.
During the red giant phase the Sun will swell until its distended atmosphere reaches out to envelop the Earth and Moon, which will both begin to be affected by gas drag-the space through which they orbit will contain more molecules.
The Moon is now moving away from Earth and by then will be in an orbit that's about 40 percent larger than today. It will be the first to warp under the Sun's influence..."

U.S. Navy Invents Railgun
The mighty railgun, that hitherto-unfeasible weapon most beloved of gamers and geeks the world over, is now a functional reality thanks to the U.S. Navy, which has produced a working 8-megajoule electromagnetic mass driver.
Spotted at the Naval Surface Warfare Center in Virginia, the navy's new weapon of choice fires but a single shot at once, unlike the hypothetical counterpart featured in classic FPS Quake. But what a shot is is, offering a 250 nautical-mile range (with an apogee of 95 miles from the Earth's surface!) and enough kinetic energy to equal the destructive power of a million-dollar missile.

Microraptor was a small, feathered dinosaur
The first flying dinosaurs took to the air in a similar way to a World War I bi-plane, a study shows.
A fresh analysis of an early feathered fossil dinosaur suggests that it dropped its hind legs below its body, adopting a bi-plane-like form.
This contrasts with earlier reconstructions showing the dinosaur maintaining its wings in a tandem pattern, a bit like a dragonfly.
Details appear in Proceedings of the National Academy of Sciences journal..."

2003 EL61 is a large, dense, rugby-ball-shaped hunk of rock with a fast rotation rate.
Professor Mike Brown has calculated that the object could be due a close encounter with the planet Neptune.
If so, Neptune's gravity could catapult it into the inner Solar System as a short-period comet.
'If you came back in two million years, EL61 could well be a comet,' said Professor Brown, from the California Institute of Technology (Caltech) in Pasadena.
'When it becomes a comet, it will be the brightest we will ever see.'"

WASHINGTON (AP) -- Two NASA space probes that visited Mars 30 years ago may have found alien microbes on the Red Planet and inadvertently killed them, a scientist is theorizing.
The Viking space probes of 1976-77 were looking for the wrong kind of life, so they didn't recognize it, a geology professor at Washington State University said.
Dirk Schulze-Makuch presented his theory in a paper delivered at a meeting of the American Astronomical Society in Seattle, Washington.
The paper was released Sunday...
