When ‘Back To Basics’ Leads To Breakthroughs In Science

(James Kelleher/The Orange County Register)

From The Christian Science Monitor:

Two examples of researchers finding amazing things by reconsidering the fundamentals.

Sometimes scientists need to take a fresh look at fundamentals to improve familiar materials. That means getting down to the basic molecular and atomic structures.

When a research group that calls itself “Liquid Stone” recently did that with cement, it found that what scientists thought they knew about the fundamental structure of that ubiquitous material just isn’t so. One team member likens the implications of their new understanding of that structure to the boost biologists got when they discovered the basic structure of the DNA molecule.

From Science Daily:

ScienceDaily (Sep. 18, 2009) — Researchers are one step closer to creating a micro-aircraft that flies with the manoeuvrability and energy efficiency of an insect after decoding the aerodynamic secrets of insect flight.

Dr John Young, from the University of New South Wales (UNSW) in Australia, and a team of animal flight researchers from Oxford University's Department of Zoology, used high-speed digital video cameras to film locusts in action in a wind tunnel, capturing how the shape of a locust's wing changes in flight. They used that information to create a computer model which recreates the airflow and thrust generated by the complex flapping movement.

From Live Science:

Fifty years ago, a typical high school science fair featured several exploding volcanoes. Today, one would expect a science fair to look far more advanced. The sad truth, however, is that standard high school science has changed very little.

"There is a growing gap between the practice of science the way researchers at Northwestern and other institutions are conducting it and what science looks like in high school," said Kemi Jona, research associate professor and director of the Office of Science, Technology, Engineering and Math Education Partnerships (OSEP) at Northwestern University. "And that gap keeps getting bigger and bigger."

Big Differences Between European Countries In Heart Risks

From Future Pundit:

The big smoker countries in Europe have much higher rates of heat disease death under age 65.

While heart disease remains the leading cause of death in Europe, mortality rates are falling in most (but not all) countries, according to new findings released by the EuroHeart mapping project.(1) However, this detailed research, part of a three-year programme to analyse cardiovascular health and prevention policies in 16 European countries, also reveals huge inequalities among countries both in the rate of cardiovascular mortality and in national prevention programmes.

• Highest rates of mortality from coronary heart disease (CHD) in men under 65 were found in Hungary (105 per 100,000 population), Estonia (104), Slovakia (74), Greece (50), Finland (48) and UK (44).
• Highest rates for women under 65 were found in Hungary (28), Estonia (20), Slovakia (19), UK (11), Greece (10) and Belgium (9).
• Lowest rates for men under 65 were found in France (17), Netherlands (22), Italy (25) and Norway (27).
• Lowest rates for women under 65 were found in Iceland (3), France (3), Slovenia (5) and Italy (5).

This pattern was also reflected (though not exactly mirrored) in risk factor prevalence, where, for example, Greece (46%), Estonia (42%), Slovakia (41%), Germany (37%) and Hungary (37%) had the highest rates of cigarette smoking.

Tyrannosaurs Flying F-14s!

The cover of this issue of Galaxy features an unusual space launch concept, but an article inside had more realistic and interesting insights.

From The Space Review:

The comic strip Calvin & Hobbes once ran a classic on a Sunday in 1995. Calvin and his tiger buddy are playing with toy dinosaurs and F-14 Tomcat fighter planes when Calvin concludes that the only thing cooler than tyrannosaurs and F-14s… is tyrannosaurs flying F-14s.

This is a scene that has been repeated throughout the history of human spaceflight, when somebody has come up with some concept for a rocket, spacecraft, whatever, that they decide can be made infinitely cooler by combining it with another concept for a rocket, spacecraft, whatever. Want to explore the icy moons of Jupiter? Let’s combine the most powerful ion engines ever built and the largest space nuclear reactor ever built and the largest rocket ever built. That would be cool. (It will also cost twenty-three billion dollars and never be built.)

Oddball Stars Explained: New Observations Solve Longstanding Mystery Of Tipped Stars

This artist's conception of the double-star system DI Herculis illustrates the key findings from the new research. Spectroscopic observations showed that the two stars are both tipped over almost horizontally, relative to the plane of their orbits around each other. Because they are rotating rapidly which creates equatorial bulges, the tidal interactions between the two slows down a regular variation in the plane of the orbits, called precession -- a slowing that had been a mystery for three decades. (Credit: Courtesy of Simon Albrecht)

From Science Daily:

ScienceDaily (Sep. 18, 2009) — A pair of unusual stars known as DI Herculis has confounded astronomers for three decades, but new observations by MIT researchers and their colleagues have provided data that they say solve the mystery once and for all.

It has long been clear that there was something odd going on in this double-star system, but it wasn't clear just what that was. The precession of the orbits of the two stars around each other — that is, the way the plane of those orbits change their tilt over time, like the wobbling of a top as it winds down — seems to take place four times more slowly than established theory says it should. The anomaly is so unexpected that at one point it was seen as possible evidence against Einstein's long-accepted theory of relativity.

Plugged-In Age Feeds a Hunger for Electricity

(Click Image to Enlarge)

From The New York Times:

With two laptop-loving children and a Jack Russell terrier hemmed in by an electric fence, Peter Troast figured his household used a lot of power. Just how much power did not really hit him until the night the family turned off the overhead lights at their home in Maine and began hunting gadgets that glowed in the dark.

“It was amazing to see all these lights blinking,” Mr. Troast said.

As goes the Troast household, so goes the planet.

Electricity use from power-hungry gadgets is rising fast all over the world. The fancy new flat-panel televisions everyone has been buying in recent years have turned out to be bigger power hogs than some refrigerators.

Warming Arctic 'Halts Migration'

From The BBC:

Milder winters in the Arctic region have led to fewer Pacific brants, a species of sea goose, migrating southwards, say researchers.

A study by the US Geological Survey (USGS) found that as many as 30% of the birds were overwintering in Alaska rather than migrating to Mexico.

Until recently, more than 90% of the species were estimated to head south.

Writing in the journal Arctic, the team said the shift coincides with warming in the North Pacific and Bering Sea.

VW Redefines ‘Car’ With A 170-MPG Diesel Hybrid

From Autopia:

Volkswagen is redefining the automobile with the L1, a bullet-shaped diesel hybrid that weighs less than 900 pounds, gets an amazing 170 mpg and might see production within four years.

The L1 concept car unveiled at the Frankfurt auto show pushes the boundaries of vehicle design and draws more inspiration from gliders than conventional automobiles. The only question the company’s engineers asked when designing the L1 was, “How would a car have to look and be built to consume as little energy as possible.” Their answer was small, light and extremely aerodynamic. Those guidelines led to a car that requires just 1.38 liters of diesel fuel to go 100 kilometers.

Solar Cycle Driven By More Than Sunspots; Sun Also Bombards Earth With High-speed Streams Of Wind

When the solar cycle was at a minimum level in 1996, the Sun sprayed Earth with relatively few, weak high-speed streams containing turbulent magnetic fields (left). In contrast, the Sun bombarded Earth with stronger and longer-lasting streams last year (right) even though the solar cycle was again at a minimum level. The streams affected Earth's outer radiation belt, posing a threat to earth-orbiting satellites, and triggered space weather disturbances, lighting up auroras in the sky at higher latitudes.

From Science Daily:

ScienceDaily (Sep. 18, 2009) — Challenging conventional wisdom, new research finds that the number of sunspots provides an incomplete measure of changes in the Sun's impact on Earth over the course of the 11-year solar cycle. The study, led by scientists at the High Altitude Observatory of the National Center for Atmospheric Research (NCAR) and the University of Michigan, finds that Earth was bombarded last year with high levels of solar energy at a time when the Sun was in an unusually quiet phase and sunspots had virtually disappeared.

The 33 Most Deadly Substances On Earth

From The Toy Zone:

Keep well away from the following 33 substances unless you want to end up 6 feet under.

1. Amanitas – Destroying Angel

Location: Europe and in the United States.

In Europe, the blossoms vary in color from pale-green or yellow-olive and along both the east and west coasts in the United States. However, they range from white to light brown in the rest of the United States.

Amanitin can be detected in the blood almost immediately. The first physical symptoms are usually nausea, vomiting, and bloody diarrhea. After an early feeling of slight discomfort, there is a sudden onset of extreme stomach pain, violent vomiting, intense thirst, and cyanosis of the extremities. Jaundice of the eyes and skin can also occur if the liver is badly affected. The patient remains conscious almost to the end, with only brief intervals of unconsciousness occurring between long lucid periods before lapsing into a coma followed by death.

Antidotes and Treatments: There are no known antidotes for Amanita poisoning; however, victims have survived after receiving liver transplants.

From The New York Times:

Paleontologists said Thursday that they had discovered what amounted to a miniature prototype of Tyrannosaurus rex, complete with the oversize head, powerful jaws, long legs — and, as every schoolchild knows, puny arms — that were hallmarks of the king of the dinosaurs.

But this scaled-down version, which was about nine feet long and weighed only 150 pounds, lived 125 million years ago, about 35 million years before giant Tyrannosaurs roamed the earth. So the discovery calls into question theories about the evolution of T. rex, which was about five times longer and almost 100 times heavier.

Pause In Arctic's Melting Trend

Photo: Walrus have been seen on Alaska's north coast in unusual numbers

From The BBC:

This summer's melt of Arctic sea ice has not been as profound as in the last two years, scientists said as the ice began its annual Autumn recovery.

At its smallest extent this summer, on 12 September, the ice covered 5.10 million sq km (1.97 million sq miles).

This was larger than the minima seen in the last two years, and leaves 2007's record low of 4.1 million sq km (1.6 million sq miles) intact.

But scientists note the long-term trend is still downwards.

How Last.fm Inspired A Scientific Breakthrough

From The Guardian:

I first saw Mendeley pitch two weeks ago – now it is on the way to changing the face of science.

The music radio site Last.fm is one of the great ideas from the UK during the first dotcom boom. Users can listen to their own songs and other tracks recommended by Last.fm's algorithms based on their tastes, including iTunes, and those of friends. It could easily have been a one-trick pony. But now a few academics have applied its serendipity to scientific research. Why can't researchers, instead of waiting anywhere up to three years for their papers to jump all the hurdles, be part of a real-time market place – a fusion of iTunes and Last.fm for science?

Spilling the beans: Women cannot keep a secret for longer than 47 hours

From The Daily Mail:

Ever wondered how long a woman can keep a secret? Well the answer, it seems, is less than two days.

Researchers found that they will typically spill the beans to someone else in 47 hours and 15 minutes.

A study of 3,000 women aged between 18 and 65 also found that four in ten were unable to keep a secret, no matter how personal or confidential the news was.

From The New Scientist:

NEUROSCIENCE could do for schools what biomedical research has done for healthcare. That's the conclusion of the Decade of the Mind (DOM) symposium last week in Berlin, Germany, to discuss how the latest findings could be used to improve education.

"In medicine, we have an excellent system in place to go from basic research to clinical practice, while in neuroscience we have the basic understanding of how the brain learns but still need to figure out how to translate this into the classroom," says Manfred Spitzer of the University of Ulm in Germany, one of the conference organisers.
