To Deflect An Asteroid, Try A Lasso, Not ANuke

From Wired Science:

To save the world from the real threat of a major asteroid impact, one engineer has imagined a scheme similar to George Bailey’s wish to lasso the moon for his sweetheart in “It’s a Wonderful Life.”

The plan is to attach a gigantic weight to an Earth-bound asteroid using an enormous cord. This crazy-sounding contraption would change the asteroid’s center of mass and subsequently its trajectory, averting a potentially catastrophic scenario.

In The Brain, Seven Is A Magic Number

From ABC News:

New Findings on Why You Have Trouble Remembering More Digits.

Having a tough time recalling a phone number someone spoke a few minutes ago or forgetting items from a mental grocery list is not a sign of mental decline; in fact, it's natural.

Countless psychological experiments have shown that, on average, the longest sequence a normal person can recall on the fly contains about seven items. This limit, which psychologists dubbed the "magical number seven" when they discovered it in the 1950s, is the typical capacity of what's called the brain's working memory.

Will Gadget Revolutionize Our Reading Habits?

From San Francisco Chronicle:

Author Jeff Vande Zande was pleased when his latest book reached a digital milestone - it "went Kindle," formatted as an electronic book for Amazon.com's portable e-reader.

Although the college English professor from Michigan is hopeful about the new market his novel, "Landscape with Fragmented Figures," might reach, he isn't quite sold on electronic readers and still prefers the look, feel and "weathered page" smell of a printed book.

"Not all books are in Kindle edition, so for me, it was a big deal," Vande Zande said. However, he believes "the Kindle is not going to revolutionize books in the same way as the Internet and the iPod have revolutionized how we take in music."

Dissection Begins On Famous Brain

From The New York Times:

SAN DIEGO — The man who could not remember has left scientists a gift that will provide insights for generations to come: his brain, now being dissected and digitally mapped in exquisite detail.

The man, Henry Molaison — known during his lifetime only as H.M., to protect his privacy — lost the ability to form new memories after a brain operation in 1953, and over the next half century he became the most studied patient in brain science.

He consented years ago to donate his brain for study, and last February Dr. Jacopo Annese, an assistant professor of radiology at the University of California, San Diego, traveled across the country and flew back with the brain seated next to him on Jet Blue.

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.

From MSNBC:

The hot, medium and cool prospects for harnessing ultimate star power.

Is nuclear fusion the ultimate energy source, or the ultimate pipe dream? Millions upon millions of dollars are being spent to find out which answer is the right one. For some technologies, the answer could come sooner than later. For others, it may be later rather than sooner.

The easiest way to access fusion power is to go outside on a sunny day: Nuclear fusion is the reaction that powers the sun, by crushing hydrogen atoms into helium atoms and converting the small blips of extra mass into energy. Hydrogen bombs, tested by the world's armies but never used on the battlefield, do the same thing.

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%.

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.

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.

From Science Daily:

Science Daily (Dec. 3, 2009) — Washington, D.C.—Hawaii may be paradise for vacationers, but for geologists it has long been a puzzle. Plate tectonic theory readily explains the existence of volcanoes at boundaries where plates split apart or collide, but mid-plate volcanoes such as those that built the Hawaiian island chain have been harder to fit into the theory. A classic explanation, proposed nearly 40 years ago, has been that magma is supplied to the volcanoes from upwellings of hot rock, called mantle "plumes," that originate deep in the Earth's mantle. Evidence for these deep structures has been sketchy, however. Now, a sophisticated array of seismometers deployed on the sea floor around Hawaii has provided the first high-resolution seismic images of a mantle plume extending to depths of at least 1,500 kilometers (932 miles).

If you're feeling a little overwhelmed by all the information you have to keep track of, you're not alone. Between the proliferation of 'smart' devices — ranging from phones to power grids — and the ever-growing Internet, the world is drowning in data. But not to despair, computer scientists like Juliana Freire are trying to help us gather and make sense of this modern monsoon of data. A computer scientist at the University of Utah, Freire's work centers on finding data that might otherwise be missed, as well as integrating and managing that data into knowledge that people can actually use. She and her collaborators have created the DeepPeep project, an attempt at integrating typical web-based data with other databases that are publicly available, but not easily found through standard methods like online searching. Freire has also created a tool called VisTrails that allows users to take several computers and 24 large, flat-screen video monitors and produce a single high-resolution visualization, such as the brain's vascular system or the dynamics of an erupting volcano.

The most direct path between two points is a straight line, but roads are rarely straight, and the ones that are can be terminally boring. Engineers around the world must calculate the most efficient routes over massive mountains, through densely populated cities and around unavoidable bodies of water, all while accounting for the ecological and financial cost of such projects. The results can be astonishing. Here are some of the world's most notable roads and why they stand out.

Cheaper, Smaller Network Of Spy Satellites Gives Troops On The Ground Their Own Eye In The Sky

Don't You Wish You Knew What's Beyond that Ridge? With Kestrel Eye satellites, grunts on the ground will be able to check out surrounding terrain from a bird's eye view in near real time. USMC

From Popular Science:

Imagine your unit is working through a valley in Eastern Afghanistan trying to root out an insurgent group that’s been operating from the mountains above. It would be strategically advantageous to know exactly who and what awaits you on the other side of each ridge, but the nearest Predator drone is busy monitoring a key mountain pass miles away. What would really be nice is a satellite – your own little eye in the sky – to beam down some real time images of the surrounding landscape. Kestrel Eye, a system of multiple lightweight, low-cost imaging satellites that can be repositioned from the field, aims to do just that.

A Uranium Shortage Could Derail Plans To Go Nuclear To Cut Carbon Emissions

From The Economist:

THERE is an awesome amount of energy tied up in an atom of uranium. Because of that, projections of the price of nuclear power tend to focus on the cost of building the plant rather than that of fuelling it. But proponents of nuclear energy—who argue, correctly, that such plants emit little carbon dioxide—would do well to remember that, like coal and oil, uranium is a finite resource.

What Happens When An Enormous Star Blows Up?

Kepler's supernova remnant. The explosion of a star is a catastrophic event. The blast rips the star apart and unleashes a roughly spherical shock wave that expands outward at more than 35 million kilometers per hour (22 million mph) like an interstellar tsunami. What might happen when a really gargantuan star -- one hundreds of times bigger than our sun -- blows up? (Credit: NASA)

From Science Daily:

Science Daily (Dec. 4, 2009) — What happens when a really gargantuan star -- one hundreds of times bigger than our sun -- blows up? Although a theory developed years ago describes what the explosion of such an enormous star should look like, no one had actually observed one -- until now.
