From Live Science:

Petunias and potatoes may actually be carnivorous plants, scientists now suggest.

Indeed, carnivorous behavior may be far more widespread in plants than commonly thought — if we take a closer look, botanists said.

At least six different kinds of killer plants have been recognized since the time of Darwin, such as Venus flytraps, which snares insects between its jaw-like leaves, and pitcher plants, which capture victims in slippery pits. These plants apparently target animals to supplement their growth in harsh, nutrient-poor habitats.

Single-Atom Transistor Discovered

a) Colored scanning electron microscope image of the measured device. Aluminum top gate is used to induce a two-dimensional electron layer at the silicon-silicon oxide interface below the metallization. The barrier gate is partially below the top gate and depletes the electron layer in the vicinity of the phosphorus donors (the red spheres added to the original image). The barrier gate can also be used to control the conductivity of the device. All the barrier gates in the figure form their own individual transistors. (b) Measured differential conductance through the device at 4 Tesla magnetic field.

Scientists: Northern Forests Need Saving, Too

From Live Science:

When fire destroys forests, or when discarded wood products are burned at the dump, carbon dioxide (CO2) escapes into the air. Hence, in part, the uproar denouncing the slash-and-burn destruction of tropical jungles. But let’s not overlook another great woodland biome: the boreal forest.

That’s the plea voiced in a recent opinion paper by Corey J.A. Bradshaw of the University of Adelaide in Australia and two colleagues. They point out that far northern forests represent a third of all remaining woodlands and 30 percent of all terrestrially stored carbon on Earth. Those vast coniferous tracts covering much of Alaska, Canada, Scandinavia, and Russia are still relatively unscathed, but they face increasing threats.

Large Moon Of Uranus May Explain Odd Tilt

A massive moon that orbited Uranus in the past may explain the planet's extreme tilt (Image: NASA/ESA/M. Showalter/SETI Institute)

From New Scientist:

Please try to resist the childish jokes, but the fact is that the odd tilt of Uranus may be the result of a particularly large moon.

Uranus spins on an axis almost parallel with the plane of the solar system, rather than perpendicular to it – though why it does this nobody knows. One theory is that the tilt is the result of a collision with an Earth-sized object, but this "hasn't succeeded in explaining much of anything", says Ignacio Mosqueira of the SETI Institute in Mountain View, California. Why, for example, are the orbits of Uranus's 27 known moons not also tilted?

From The Telegraph:

The Earth may be 50 per cent more sensitive to the warming effect of carbon dioxide greenhouse gas than has previously been thought, scientists claim.

A new study suggests bigger cuts in carbon dioxide (CO2) emissions may be needed to prevent drastic long term climate change.

The evidence was obtained by scientists looking back three million years to the Pliocene epoch, when global temperatures were 5.4F (3C) to 9F (5C) higher than they are today.

They found that levels of CO2 in the atmosphere at the time should not have produced such a warm world.

Nanowires Key To Future Transistors, Electronics

Researchers are closer to using tiny devices called semiconducting nanowires to create a new generation of ultrasmall transistors and more powerful computer chips. The researchers have grown the nanowires with sharply defined layers of silicon and germanium, offering better transistor performance. As depicted in this illustration, tiny particles of a gold-aluminum alloy were alternately heated and cooled inside a vacuum chamber, and then silicon and germanium gases were alternately introduced. As the gold-aluminum bead absorbed the gases, it became "supersaturated" with silicon and germanium, causing them to precipitate and form wires.

From Science Daily:

Science Daily (Dec. 6, 2009) — Getting the correct balance of proteins in our diet may be more important for healthy ageing than reducing calories, new research funded by the Wellcome Trust and Research into Ageing suggests.

The research may help explain why 'dietary restriction' (also known as calorie restriction) -- reducing food intake whilst maintaining sufficient quantities of vitamins, minerals and other important nutrients -- appears to have health benefits. In many organisms, such as the fruit fly (drosophila), mice, rats and the Rhesus monkey, these benefits include living longer. Evidence suggests that dietary restriction can have health benefits for humans, too, though it is unclear whether it can increase longevity.

Copying Birds May Save Aircraft Fuel

Photo: Corbis

From The Economist:

BOTH Boeing and Airbus have trumpeted the efficiency of their newest aircraft, the 787 and A350 respectively. Their clever designs and lightweight composites certainly make a difference. But a group of researchers at Stanford University, led by Ilan Kroo, has suggested that airlines could take a more naturalistic approach to cutting jet-fuel use, and it would not require them to buy new aircraft.

The answer, says Dr Kroo, lies with birds. Since 1914, and a seminal paper by a German researcher called Carl Wieselsberger, scientists have known that birds flying in formation—a V-shape, echelon or otherwise—expend less energy. The air flowing over a bird’s wings curls upwards behind the wingtips, a phenomenon known as upwash. Other birds flying in the upwash experience reduced drag, and spend less energy propelling themselves. Peter Lissaman, an aeronautics expert who was formerly at Caltech and the University of Southern California, has suggested that a formation of 25 birds might enjoy a range increase of 71%.

During the first collisions of the LHC's twin beams of protons, a machine called A Large Ion Collider Experiment, or ALICE, collected the results from a proton-proton smashup.

From Science Daily:

ScienceDaily (Dec. 4, 2009) — The rising level of atmospheric carbon dioxide may be fueling more than climate change. It could also be making some trees grow like crazy.

That is the finding of a new study of natural stands of quaking aspen, one of North America's most important and widespread deciduous trees. The study, by scientists from the University of Wisconsin-Madison and the University of Minnesota at Morris (UMM) and published December 4 in the journal Global Change Biology, shows that elevated levels of atmospheric carbon dioxide during the past 50 years have boosted aspen growth rates by an astonishing 50 percent.

Rural America Surprisingly Prosperous, Study Finds

(Click Image to Enlarge)
Much of rural America is prosperous, says a study that used specific criteria to evaluate community success. To qualify as prosperous, U.S. counties had to have lower poverty levels, unemployment rates, high school drop outs and housing problems than the nation as a whole. Here, a map showing the prosperity of U.S. counties. Counties that do better than the nation on all four criteria are colored red. Those that do better on three criteria are red-orange, two criteria are orange, one criteria is yellow and none is white. Credit: Andrew Isserman, Edward Feser, Drake Warren, University of Illinois.

From Live Science:

For many people "rural" is synonymous with low incomes, limited economic opportunity, and poor schools. However, a recent study found that much of rural America is actually prosperous, particularly in the Midwest and Plains.

Researchers just had to look at things differently to see the prosperity.

The study — announced today and based on date from the year 2000 — analyzed unemployment rates, poverty rates, high school drop-out rates, and housing conditions to identify prospering communities. The result: One in five rural counties in the United States is prosperous, doing better than the nation as a whole on all these measures.

Nobel Prizes Hit By The Financial Crisis?

Nobel Prize Foundation Frets Over Its Finances -- ABC News

STOCKHOLM (Reuters) - The Nobel Foundation might have to reduce the money it awards winners of its prestigious prizes due to the effects of the global financial crisis, its director said on Saturday.

The foundation will give 10 million Swedish crowns ($1.5 million) for each prize this year as it has done for most of the last decade. But the downturn could strain resources for future prizes.

"It might be in the future we would be forced to lower the prize," Michael Sohlman, Executive Director for the Nobel Foundation, told a press briefing. "We have sailed the storm, but have taken on some water."
