From Science Daily:

ScienceDaily (Oct. 14, 2008) — University of British Columbia archaeologists have dug up a mystery worthy of Indiana Jones, one that includes a tomb, skeletons and burial rites with both Christian and pagan elements.

This summer, Prof. Roger Wilson led excavations at Kaukana, an ancient Roman village located near Punta Secca, a small town in the south-eastern province of Ragusa in Sicily.

Combing through the sand-buried site, the 15-member team made a series of startling discoveries. Central to the mystery was finding a tomb inside a room in a house dating from the sixth century AD.

Wilson explains that tombs during this period are normally found only in cemeteries outside the built-up area of a town, or around the apse of a church. And since the building was substantial with mortared walls and internal plaster, this would have been likely a tomb for the wealthy.

From Live Science:

Lights may soon do more than just shine in dark places – they might wirelessly connect your computer, phone or car to the Internet.

Sounds strange, but consider this. Remote controls already use infrared light to communicate with TVs and DVD players. Turning ceiling and reading lamps into wireless access points could allow you to get your Internet fix almost anywhere.

"We can provide ubiquitous communication if we have network access wherever there's lighting," said Thomas Little, a computer engineer at Boston University.

These aren't just any lights, though. Little and other researchers hope to piggyback on the spread of light-emitting diode (LED) light bulbs, which are finding favor as low-energy, long-lasting alternatives to the more conventional incandescent or fluorescent light bulbs.

Step Aside, Chicken Soup: Eight Cold Elixirs

From ABC News:

Spanning the Globe in Search of Alternative Home Remedies for the Common Cold
No matter where you live or what language you speak, the symptoms of a coldare understood the world over -- no translation required: Your throat feels sore; your nose runs; you might cough or sneeze; and your body aches.

It's time to crawl under the covers and get the extra rest you need.

But a cold virus will need some coaxing to hit the road. Colds rarely make a quick exit and usually take about a week to run their course.

That's where the time-honored tradition of folk medicine comes into play.

Faced with a cold and a lack of modern medicine, our ancestors turned to nature for its treatments. And throughout the world, parts of plants -- the roots, stems, leaves, fruits and flowers -- are used to ease a cold and its symptoms.

For U.S. Astronauts, A Russian Second Home

From The New York Times:

STAR CITY, Russia — Garrett Reisman was on his way to this formerly secret military base for several weeks of training, making his way through Kennedy Airport, when his cellphone rang. It was his boss, Steven W. Lindsey, the head of NASA’s astronaut office.

“Come back to Houston. They’ve canceled your training — they’re playing hardball,” Mr. Reisman recalled his boss saying. He was caught in a momentarily important dispute between NASA and the Russian space agency, Roscosmos.

Ultimately, Mr. Reisman’s aborted trip was just a bump in the road on the way to space: he spent three months aboard the International Space Station earlier this year, performed a spacewalk and even traded jokes over a video link with Stephen Colbert.

Everyone who works with the Russian space program has similar stories to tell of implacable bureaucrats, byzantine rules and decisions that seem capricious at best. And many of those stories are played out here in Star City, where cosmonauts and, now, astronauts from all over the world train to fly on Russian Soyuz spacecraft to go to the $100 billion International Space Station.

Introducing the World’s Largest Solar Powered Winery

(Photo from Treehugger)

From Treehugger:

The largest solar installation of any winery in the world is set to be built for Constellation Wines’ Gonzalez winery in Monterrey County, CA by Pacific Power Management. Mitsubishi solar panels will cover 170,000 square feet on the winery warehouse roof, and will generate 1,700,000 kilowatt hours a year—enough to power over 50 percent of the winery’s energy needs.

Solar Powered Wine-Making, Solar Powered Living
What’s more, during the summer months when the winery isn’t operating at full capacity (it doesn’t process grapes in summer months), the electricity will be exported in order to power 25 percent of the energy needs of surrounding residential areas—1,695 homes in the city of Gonzalez.

This may very well be the most expansive effort to power a winery with alternative energy (though there are more than a few very green wineries already in operation, and it won't lay claim to the first carbon neutral winery).

Haemorrhagic Virus Carried By Common African Mouse

From the New Scientist:

Three people have died and another is seriously ill with a previously unknown strain of a virus carried by a common African rodent. The virus requires close contact to spread, but experts warn that more like it could be circulating.

A 36-year-old woman on a small farm outside the Zambian capital Lusaka developed flu-like symptoms in early September. When they worsened she was taken by air ambulance to South Africa, where she died.

Alarms were raised after the ambulance paramedic and the nurse who attended her also died after developing similar symptoms two weeks later. The nurse who tended the paramedic is also in a serious condition.

On Sunday South Africa's National Institute for Communicable Diseases announced that the victims were infected by an arenavirus, one of a family of viruses carried by rodents.

"They are very widespread," says Bob Swanepoel, former head of the NICD and one of the world's leading experts on haemorrhagic viruses. In Africa, arenaviruses are carried, with no symptoms, by the multimammate mouse, a common farm pest sold in Europe as a "pocket pet".

From Swissinfo:

Despite the complexity and high research and development costs, scientists are convinced they can unlock the massive power of nuclear fusion within a generation.

On Monday the International Atomic Energy Agency (IAEA) and the Thermonuclear Experimental Reactor Organisation (ITER) signed a cooperation agreement at the opening of an IAEA fusion energy conference, held in Geneva.

"ITER is one of the most important scientific projects in the world," said IAEA's director general, Yuri Sokolov.

ITER, or "the way" in Latin, is an experimental reactor being built in Cadarache, southern France, which has a practical goal: to establish whether fusion, the nuclear reaction that powers the sun and the hydrogen bomb, can be tamed to generate useful power on Earth.

Break Out The Bubbly: White Wine May Be Good For You

From The New Scientist:

White wine lovers can feel a little less guilty about their habit. New research suggests that white varieties may offer similar heart benefits to red wines.

Rats that were fed white wine as part of their diet suffered less heart damage during cardiac arrest, compared to animals fed only water or grain alcohol. These benefits were similar to animals that ingested a red wine or its wonder ingredient found only in grape skin, resveratrol.

White wine, made from the pulp of the grape but not the skin, contains no resveratrol, which led many to pin the so-called "French paradox" – high fat intake but low rates of heart disease – on moderate consumption of red wines.

Not just reds, says Dipak Das, a molecular biologist at the University of Connecticut School of Medicine in Farmington. "The flesh of the grape can do the same job as the skin."

How We Evolve

From Seed Magazine:

When the previous generation of life scientists was coming up through the academy, there was a widespread assumption, not always articulated by professors, that human evolution had all but stopped. It had certainly shaped our prehuman ancestors — Australopithecus, Paranthropus, and the rest of the ape-men and man-apes in our bushy lineage — but once Homo sapiens developed agriculture and language, it was thought, we stopped changing. It was as though, having achieved its aim by the seventh day, evolution rested. "That was the stereotype that I learned," says population geneticist and anthropologist Henry Harpending. "We showed up 45,000 years ago and haven't changed since then."

The idea makes a rough-and-ready kind of sense. Natural selection derives its power to transform from the survival of some and the demise of others, and from differential reproductive success. But we nurse our sick back to health, and mating is no longer a privilege that males beat each other senseless to secure. As a result, even the less fit get to pass on their genes. Promiscuity and sperm competition have given way to spiritual love; the fittest and the unfit are treated as equals, and equally flourish. With the advent of culture and our fine sensibilities, the assumption was, natural selection went by the board.

From Science Daily:

ScienceDaily (Oct. 11, 2008) — Cranberries are tart, tiny fruits packed with powerful antioxidants. The small, red berries offer a wide variety of health benefits. Not only are cranberries a healthy, low-calorie snack, but they can also play a significant role in preventing urinary tract infections, reducing the risk of gum disease and much more. In fact, studies show that the significant amounts of antioxidants in cranberries may help protect against heart disease, cancer, and other diseases.

The good news about cranberries is spreading, resulting in growing consumer demand for fresh cranberries and cranberry products. This demand has led to increased interest in finding ways to extend the shelf life of the popular fruit. Setting out to determine the optimum conditions for storing fresh cranberries, Charles F. Forney. a research scientist in Postharvest Physiology at the Atlantic Food and Horticulture Research Centre in Nova Scotia, Canada, conducted a study of fresh cranberries and their postharvest life. Forney's study was published in the April 2008 issue of HortScience.

Promising New Material Could Improve Gas Mileage

From Space Daily:

ScienceDaily (Oct. 10, 2008) — With gasoline at high prices, it's disheartening to know that up to three-quarters of the potential energy you are paying for is wasted. A good deal of it goes right out the tailpipe instead of powering your car.

Now a Northwestern University-led research team has identified a promising new material that could transform a technology that currently cools and heats car seats -- thermoelectrics -- into one that also efficiently converts waste heat into electricity to help power the car and improve gas mileage.

The researchers discovered that adding two metals, antimony and lead, to the well-known semiconductor lead-telluride, produces a thermoelectric material that is more efficient at high temperatures than existing materials. The results are published online in the journal Angewandte Chemie.

Animals Have Personalities, Too

From Live Science:

We know our siblings and in-laws have personalities — sometimes to a fault. But science recently has revealed that such individual differences are widespread in the animal kingdom, even reaching to spiders, birds, mice, squid, rats and pigs.

Now a new mathematical model helps to explain how and why such animal temperaments develop over time.

The model explains a central question of both animal and human personality — why certain individuals are more rigid or flexible than others, and why some change their behavior in response to changes in their environment while others do not.

The answer, says Franz Weissing of the University of Groningen, the Netherlands, comes down to costs and benefits. A group in which both rigid and flexible personality types co-exist makes for an optimal system, his model shows.

The field of animal-personality study is starting to gain some substance and credibility, said University of Texas psychologist Sam Gosling, who does research in this field.

A New Explosive

A high-energy-density nitrate ester (1) with unique properties was synthesized in good yield in a three-step process. Destructive stimuli studies and explosive performance calculations show that (1) has similar performance properties to those of well-characterized explosives.

From E! Science News:

Since the discovery of nitroglycerin in 1846, the nitrate ester group of compounds has been known for its explosive properties. A whole series of other nitrate esters have been subsequently put to use as explosives and fuels. A research team led by David E. Chavez at Los Alamos National Laboratory (USA) has now developed a novel tetranitrate ester. As reported in the journal Angewandte Chemie, the compound has a particularly interesting characteristic profile: it is solid at room temperature, is a highly powerful explosive, and can be melt-cast into the desired shape. Nitrate esters are organic nitric acid compounds that can contain enormous explosive force. However, their liquid physical state makes handling very difficult. By mixing in various other components, Alfred Nobel developed dynamite, a distinctly safer and easier to handle nitroglycerine-based explosive. The only solid nitrate ester used as an explosive before is nitropenta. Because of its high melting point of about 140 °C, nitropenta must be pressed into the desired form.

New Spacecraft to Explore Interstellar Boundary -- Popsci

NASA's IBEX craft is heading out this month to map the edges of the solar system

The "termination shock" sounds like the stuff science fiction movies are made of. In reality, it marks the boundary between our solar system and interstellar space. The invisible "shock" forms as our sun's solar winds begin to encounter the gases and magnetic fields of outer space, which slows the winds down abruptly.

On October 19, NASA will launch the first spacecraft designed to image and map the interactions that take place in this boundary zone. The Interstellar Boundary Explorer, or IBEX, will be propelled from the Kwajalein Atoll into a high-altitude orbit that will eventually take it about 200,000 miles from Earth, where it will capture images of processes taking place in the termination shock and beyond.

"The interstellar boundary regions are critical because they shield us from the vast majority of dangerous galactic cosmic rays, which otherwise would penetrate into Earth's orbit and make human spaceflight much more dangerous," said David J. McComas, principal investigator of the IBEX mission and senior executive director the Space Science and Engineering Division at the Southwest Research Institute.

From Watts With That:

As many readers know, the predictions for record low sea ice minimums in 2008 were not met, and 2008 ended up about 9% higher than in 2007 at the end of the season. See the report here.

Now in looking at AMSR-E satellite data, the red line on the graph below, one can see that the recovery is at a significantly faster rate than in recent years.

I’m not one to read much into this, as to do so would be to make the same mistake as was done earlier this year when the NSIDC melt trend led one researcher there to conclude that we’d see an “ice free north pole”.

Babies Know Happy From Sad Songs

(Photo from Baby Pictures Photos)

From Live Science:

Babies as young as 5 months can distinguish an upbeat tune, such as "Ode to Joy" from Beethoven's Ninth Symphony, from a lineup of gloomy tunes.

Researchers displayed an emotionally-neutral face for the baby while sad music played. When the baby looked away from the face, the music stopped and a new sad song would start. When the happier "Ode to Joy" played, the babies stared at the face three to four seconds longer, suggesting they were interested in the shift.

By 9 months old, babies can do the opposite, picking out the sorrowful sound of Beethoven's Seventh Symphony from a pack of happy pieces.

The finding is another example of how babies make sense of the world long before they can talk, said Brigham Young University psychology professor and study author Ross Flom.

Blood Test Finds Coronary Disease

(Photo from NHLBI)

From The New Observer:

A simple blood test could soon replace expensive and invasive exams to detect coronary artery disease.

The test, announced Wednesday by doctors at Duke, is being developed after the discovery of genetic markers that show the presence and intensity of blockage in coronary artery disease, said a Duke cardiologist who co-authored research on the link.

Such a blood test could save millions of dollars annually by allowing some patients to avoid risky procedures in which catheters are inserted into patients' arteries.

"I think it is a big deal," Dr. William E. Kraus, a Duke cardiologist, said in an interview Wednesday. "What we want is a test that tells us the status of your disease today and if what you have is heart disease." Kraus' research was published in the medical journal Circulation: Cardiovascular Genetics.

Current detection of the disease -- the leading cause of death in the United States and a top killer in North Carolina, with 23,610 deaths in 2006 -- can require expensive tests such as echocardiograms, stress tests and imaging techniques that use radiation.

"A blood-based test to diagnose coronary artery disease would be less invasive and risky and would prevent patients from [receiving] radiation exposure," Kraus said in a statement.

In Puppy Play, It's Ladies First

She's the Boss: During puppy play, young males sometimes put themselves in a position where they can be taken advantage of by their female playmates. The early behavior could serve them well later in life, say researchers. (Photo: From Discovery)

From Discovery:

Oct. 9, 2008 -- It may not be such a dog-eat-dog world after all, at least among puppies. A new study has found that young male dogs playing with female pups will often let the females win, even if the males have a physical advantage.

Male dogs sometimes place themselves in potentially disadvantageous positions that could make them more vulnerable to attack, and researchers suspect the opportunity to play may be more important to them than winning.

Such self-handicapping has been documented before in red-necked wallabies, squirrel monkeys, hamadryas baboons and even humans, all of which frequently take on defensive positions when playing with youngsters, in particular.

The gentlemanly dog behavior is even accompanied with a bow.

From Christian Science Monitor:

Worldwide computer grids mean even small-timers can contribute to ‘big science.’

Elizabeth City State University in North Carolina is not the first name that pops up in conversations about centers of polar science.

Tucked at the tip of a branch of Albemarle Sound, along the state’s northeast coast, the well-regarded, historically African-American university focuses largely on undergraduate education. But it’s also taking part in cutting-edge Arctic and Antarctic science as a key player in PolarGrid – a powerful, sophisticated computer network researchers use to analyze images of ice sheets in Greenland and Antarctica and model their behavior.

It’s part of the burgeoning world of e-Science – a realm where the questions are big, cutting across once-disparate disciplines. And the answers often demand enormous amounts of number crunching through networks of interconnected computing centers at universities and laboratories around the world – a process known as grid computing.
