Historical Colonization versus Historical Navies and Future Spaceships


From Next Big Future:

In terms of the scale of the effort for colonizing North America, I think it is useful to compare the size of the naval fleets of the time and other historical benchmarks. We know how large the military is today and the share of the total economy that it has. It will be more useful to approximate how large the interplanetary space travel industry will need to be before an interstellar colonization expedition would be a reasonably sustainable activity.

This relates to the discussion of spaceships and whether interstellar spaceships will happen

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.

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.

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%.

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).

First Direct Observation Of A Planet-Like Object Orbiting Star Similar To Sun

This August 2009 discovery image of GJ 758 B was taken with the Subaru Telescope's HiCIAO instrument in the near infrared, which measures and records differences in heat. Without the special technique employed here (angular differential imaging), the star's glare would overwhelm the light from the planet candidates. The planet-like object, GJ 758 B, is circled as B in the lower right portion of the image. An unconfirmed companion planet or planet-like object, C, can be viewed above B.

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.
