Powerful Ideas: Beer Waste Makes Fuel
From Live Science:
After beer is made, the waste from breweries could help generate power, researchers now suggest.
One problem brewers face is what to do with the thousands of tons of grain left over at the end of the brewing process. In the past, they just sold the waste to farmers who either fed it to their animals or spread it on their fields as fertilizer. However, in Europe, given reductions in cattle breeding and stricter regulations on what waste is allowed on land, neither option is as easy anymore.

Will Antitrust Probe Keep Microsoft, Yahoo Apart?
From The Miami Herald/AP:
WASHINGTON -- Yahoo Inc. and Microsoft Corp. hope that by joining forces, they can tilt the balance of power in Internet search away from Google Inc. First, however, Yahoo and Microsoft have to convince regulators that their plan won't hurt online advertisers and consumers.

Cutting The Cord: America Loses Its Landlines
From The Economist:
Ever greater numbers of Americans are disconnecting their home telephones, with momentous consequences.
MUCH has been made of the precipitous decline of America’s newspapers. According to one much-cited calculation, the country’s last printed newspaper will land on a doorstep sometime in the first quarter of 2043. That is a positively healthy outlook, however, compared with another staple of American life: the home telephone. Telecoms operators are seeing customers abandon landlines at a rate of 700,000 per month. Some analysts now estimate that 25% of households in America rely entirely on mobile phones (or cellphones, as Americans call them)—a share that could double within the next three years. If the decline of the landline continues at its current rate, the last cord will be cut sometime in 2025.

Moonquake Mystery Deepens
From Earth Magazine:
Between 1969 and 1972, five Apollo missions installed seismic stations at their landing sites on the nearside of the moon. Because the moon was thought to be seismically dead, the instruments were left almost as an afterthought to detect meteor strikes. But from the time the stations were switched on until they were decommissioned in 1977, they recorded hundreds of internally generated moonquakes, some as strong as magnitude 5.5 on the Richter scale.

New Way To Reproduce A Black Hole?
From Science Daily:
ScienceDaily (Aug. 22, 2009) — Despite their popularity in the science fiction genre, there is much to be learned about black holes, the mysterious regions in space once thought to be absent of light. In a paper published in the August 20 issue of Physical Review Letters, Dartmouth researchers propose a new way of creating a reproduction black hole in the laboratory on a much-tinier scale than their celestial counterparts.
The new method to create a tiny quantum sized black hole would allow researchers to better understand what physicist Stephen Hawking proposed more than 35 years ago: black holes are not totally void of activity; they emit photons, which is now known as Hawking radiation.

Phones, PCs Put E-Book Within Reach Of Kindle-Less
Many phones are now sophisticated enough, and have good enough screens, that they can be used as e-book reading devices. They can now rival the Kindle, pictured. (Mark Lennihan/AP)
From Christian Science Monitor:
Amazon's pioneering device may not dominate the market for long. Many phones are now sophisticated enough to be used as e-book reading devices.
A few weeks ago, Pasquale Castaldo was waiting at the Dallas-Fort Worth airport for a delayed flight, when a man sitting across from him pulled out an Amazon Kindle book-reading device.
“Gee, maybe I should think about e-books myself,” Castaldo thought.
He didn’t have a Kindle, but he did have a BlackBerry. He pulled it out and looked for available applications. Sure enough, Barnes & Noble Inc. had just put up an e-reading program. Castaldo, 54, downloaded it, and within a minute, began reading Jane Austen’s “Pride and Prejudice.”

How Do Scientists Really Use Computers?
From American Scientist:
Computers are now essential tools in every branch of science, but we know remarkably little about how—or how well—scientists use them. Do most scientists use off-the-shelf software or write their own? Do they really need state-of-the-art supercomputers to solve their problems, or can they do most of what they need to on desktop machines? And how much time do grad students really spend patching their supervisors’ crusty old Fortran programs?

Universal Vaccine Could Put An End To All Flu
From New Scientist:
IT IS not a nice way to die. As the virus spreads through your lungs, your immune system goes into overdrive. Your lungs become leaky and fill with fluid. Your lips and nails, then your skin, turn blue as you struggle to get enough oxygen. Basically, you drown.
Flu can kill in other ways, too, from rendering you vulnerable to bacterial infections to triggering heart attacks. Of course, most flu strains, including (so far) the 2009 pandemic virus, cause only mild symptoms in the vast majority of people. But with 10 to 20 per cent of people worldwide getting flu every year, that still adds up to a huge burden of illness - and even in a good year some half a million die.

The Origin of Zero
From Scientific American:
Much ado about nothing: First a placeholder and then a full-fledged number, zero had many inventors.
The number zero as we know it arrived in the West circa 1200, most famously delivered by Italian mathematician Fibonacci (aka Leonardo of Pisa), who brought it, along with the rest of the Arabic numerals, back from his travels to north Africa. But the history of zero, both as a concept and a number, stretches far deeper into history—so deep, in fact, that its provenance is difficult to nail down.

Human Lifespans Nearly Constant for 2,000 Years
From Live Science:
The Centers for Disease Control and Prevention, often the harbinger of bad news about e. coli outbreaks and swine flu, recently had some good news: The life expectancy of Americans is higher than ever, at almost 78.
Discussions about life expectancy often involve how it has improved over time. According to the National Center for Health Statistics, life expectancy for men in 1907 was 45.6 years; by 1957 it rose to 66.4; in 2007 it reached 75.5. Unlike the most recent increase in life expectancy (which was attributable largely to a decline in half of the leading causes of death including heart disease, homicide, and influenza), the increase in life expectancy between 1907 and 2007 was largely due to a decreasing infant mortality rate, which was 9.99 percent in 1907; 2.63 percent in 1957; and 0.68 percent in 2007.

That’s the key message from the independent panel chartered to rethink NASA’s future. The Review of Human Space Flight Plans group also is looking at a variety of imaginative approaches to space exploration that could make NASA’s future seem less like reheated Apollo leftovers.

Why We Lie So Much
From Time Magazine:
A professor of psychology at the University of Massachusetts, Robert Feldman has spent most of his career studying the role deception plays in human relationships. His most recent book, The Liar in Your Life: How Lies Work and What They Tell Us About Ourselves, lays out in stark terms just how prevalent lying has become. He talked to TIME about why we all need a dose of honesty.

Dark Energy – How Would You Explain It?

From The Telegraph:
I firmly believe that it should be possible to explain every scientific theory, experiment or concept in simple language that can be understood by a layperson.
However some subjects are so complicated they appear to defy simplification.
Dark energy, which made the news this week, is one such subject. Even the Oxford Dictionary of Science admitted that its nature is not known.
Has anyone come across a simple explanation?

The Origin Of Dogs
From Scientific American:
Fido's cousins may be Eurasian wolves, but new findings complicate the details of domestication.
From precious pomeranians to mangy mutts, all domestic dogs (Canis familiaris) seem to be descended from the Eurasian gray wolf (Canis lupis). But what we still don't know is exactly when and where our best friends transformed from predators into partners. And such knowledge might help solve the long-disputed question of exactly why dogs were the first animal to be domesticated.

A Step Closer To 'Synthetic Life'
From The BBC:
In what has been described as a step towards the creation of a synthetic cell, scientists have created a new "engineered" strain of bacteria.
A team successfully transferred the genome of one type of bacteria into a yeast cell, modified it, and then transplanted into another bacterium.
This paves the way to the creation of a synthetic organism - inserting a human-made genome into a bacterial cell.

In Hot Water: World Sets Ocean Temperature Record
From Yahoo News/AP:
WASHINGTON – Steve Kramer spent an hour and a half swimming in the ocean Sunday — in Maine. The water temperature was 72 degrees — more like Ocean City, Md., this time of year. And Ocean City's water temp hit 88 degrees this week, toasty even by Miami Beach standards.
Kramer, 26, who lives in the seaside town of Scarborough, said it was the first time he's ever swam so long in Maine's coastal waters. "Usually, you're in five minutes and you're out," he said.

Drop In World Temperatures Fuels Global Warming Debate
From McClatchy News:
WASHINGTON — Has Earth's fever broken?
Official government measurements show that the world's temperature has cooled a bit since reaching its most recent peak in 1998.
That's given global warming skeptics new ammunition to attack the prevailing theory of climate change. The skeptics argue that the current stretch of slightly cooler temperatures means that costly measures to limit carbon dioxide emissions are ill-founded and unnecessary.
