Why The Chile Earthquake Aftershock Was So Big



From Live Science:

The whopping 7.2-magnitude aftershock that rattled Chile again today is nothing unusual following such a large original earthquake, scientists say.

The aftershock, which struck at about 11:40 am local time, may sound surprisingly strong, given that it is bigger than the original earthquake that decimated Haiti in January, but it wasn't unexpected to scientists, said Don Blakeman, a geophysicist with the United States Geological Survey.

From The Guardian:

Women come out best in listening and recollection tests in study by University of London's Institute of Education.

It's been an endless source of aggravation between the sexes; how can men so easily forget birthdays, anniversaries, and even friends' names?

Not, it seems, because they cannot be bothered to remember. Research suggests that, in middle age at least, absent-minded-ness is a particularly male problem.

Pretty In Pink: One Of World's Rarest Camellias Blooms In London Conservatory

A 'Middlemist's red' camellia, thought to be one of only two examples of the variety in the world, at the Chiswick House Gardens conservatory, London

From The Daily Mail:

It lived through the Battle of Trafalgar, survived the reign of Victoria and escaped unharmed from a Blitz bomb.

So it's going to take more than a harsh British winter to stop one of the world's rarest camellias from bursting into flower.

This week - in a welcome sign that spring is just around the corner - the "Middlemist's red" has put on one of its most spectacular displays in many years.

From Popular Science:


Methane hydrate crystals show promise as a clean energy source.

When methane and freezing cold water fuse under tremendous pressure, they create a substance as paradoxical as it coveted: burning ice. Earlier in the year, a report from the National Research Council identified the combustible water, also known as methane hydrate, as a potential source of natural gas. Now, according to the Chinese news organization Xinhau, China is joining the US, Japan, and South Korea in the hunt for this weird mineral.

Extreme Physics At The Ends Of The Earth



From New Scientist:

When science was young, the experiments were simple and the breakthroughs came easily - or so it seems in hindsight. Think of Galileo rolling a ball down an inclined plane, or aiming a simple tube, with a lens at each end, at the night sky. Or picture Michael Faraday discovering electromagnetic induction just by tinkering with a battery, an iron ring and some coils of wire.

Quantum Computing Thrives On Chaos


From Wired/Science News:

Embracing chaos just might help physicists build a quantum brain. A new study shows that disorder can enhance the coupling between light and matter in quantum systems, a find that could eventually lead to fast, easy-to-build quantum computers.

Quantum computers promise superfast calculations that precisely simulate the natural world, but physicists have struggled to design the brains of such machines. Some researchers have focused on designing precisely engineered materials that can trap light to harness its quantum properties. To work, scientists have thought, the crystalline structure of these materials must be flawlessly ordered — a nearly impossible task.

Obama Facing Uprising Over New NASA Strategy

From Yahoo News/Reuters:

WASHINGTON, March 10 - U.S. President Barack Obama is trying to tamp down an uprising in politically vital Florida against a new strategy for NASA that has rankled space veterans and lawmakers and sparked fears of job losses.

Obama's decision to kill NASA's Constellation program to launch astronauts into orbit and return Americans to the moon has prompted soul-searching on whether the United States is prepared to cede a pre-eminent space role to Russia and China.

Smell of Salt Air Surprisingly Detected a Mile High and 900 Miles Inland

The reddish glow from the city lights of Boulder, Colo., is the result in part of the light being scattered by haze particles. UW scientists have discovered unexpected chemistry involving the pollutants that make up the haze. (Credit: Phil Armitage)

From Science Daily:

Science Daily (Mar. 11, 2010) — The smell of sea salt in the air is a romanticized feature of life along a seacoast. Wind and waves kick up spray, and bits of sodium chloride -- common table salt -- can permeate the air.

It is believed that as much as 10 billion metric tons of chloride enters the air mass through this process each year, but just a tiny fraction -- perhaps one-third of 1 percent -- does anything but fall back to the surface.

From Live Science:

Christine Ortiz is an associate professor of Materials Science and Engineering at the Massachusetts Institute of Technology in Cambridge, Mass. Recently Ortiz and a team of researchers at the National Science Foundation-supported Materials Research Science and Engineering Center at MIT reported on the protective armor of a rare iron-plated gastropod mollusk, the so-called "scaly-foot gastropod." The snail thrives 2.5 miles below the central Indian Ocean, within the Kairei Indian hydrothermal vent field, and its shell is fused with granular iron sulfide. Understanding the physical and mechanical properties of the snail could improve load-bearing and protective materials in everything from aircraft hulls to sports equipment. You can read more about the iron-armored snail in a recent NSF press release, and you can learn more about Ortiz as she answers the ScienceLives 10 questions below.

How It Works: Upscaling 2-D Video To 3-D

Watch 2-D Home Movies of Yourself Watching 3-D TV...In 3-D!

From Popular Science:

3-D TVs are finally going on sale--sans content. So some sets are claiming the ability to add a third dimension to your 2-D broadcasts.

More than a year after the first consumer 3-D-ready HDTVs were demoed at CES, the next generation of sets are going on sale this week. But, aside from the new TVs, glasses, and Blu-ray players, the question of content remains. While there are already brand partnerships with networks like Discovery and ESPN, that's just the tip of the iceberg. As an alternative, the two companies with 3-D TVs but without major brand-name cable partners (Samsung and Toshiba) showed off sets that could convert 2-D video to 3-D in real time.

From New Scientist:

THE regenerating liquid-metal robots in the Terminator movies have a cosmic relation: incoming asteroids that quickly reassemble if blasted by a nuclear bomb.

If a sizeable asteroid is found heading towards Earth, one option is to nuke it. But too small a bomb would cause the fragments to fly apart only slowly, allowing them to clump together under their mutual gravity. Simulations now show this can happen in an alarmingly short time.

Climategate: Three Of The Four Temperature Datasets Now Irrevocably Tainted

From Pajamas Media:

The warmist response to Climategate — the discovery of the thoroughly corrupt practices of the Climate Research Unit (CRU) — was that the tainted CRU dataset was just one of four independent data sets. You know. So really there’s no big deal.

Thanks to a FOIA request, the document production of which I am presently plowing through — and before that, thanks to the great work of Steve McIntyre, and particularly in their recent, comprehensive work, Joseph D’Aleo and Anthony Watts — we know that NASA’s Goddard Institute for Space Studies (GISS) passed no one’s test for credibility. Not even NASA’s.

Tricks To Keep Your Device’s Battery Going And Going

Andy Chen/The New York Times

From New York Times:


If you’re a recent convert to smartphones, you’re probably still discovering all the amazing things that your new BlackBerry, Android phone or iPhone can do. But one thing you most likely found out right away: the more you do, the shorter your phone’s battery lasts.

While a standard cellphone’s charge can easily go three days or more, many smartphone owners are dismayed to learn that their new mobile toy requires charging every 24 hours, or even more often. It was great that I could use one device — my iPhone — to check my calendar and respond to multiple incoming calls during January’s Consumer Electronics Show, but I paid the price when its battery died at 2 p.m.

Early Earth Embroiled In Constant Solar Storm

The larger auroral oval relative to the modern is the result of a weaker dipole magnetic field and stronger solar wind dynamic pressure. The auroral intensity is brighter due to solar wind densities many times greater than those today, and the dominant color reflects greater energies of the precipitating particles and the mildly reducing Paleoarchean atmosphere. Credit: J. Tarduno and R. Cottrell/University of Rochester

From Cosmos:

SYDNEY: A weak magnetic field and powerful solar wind stripped water from the early Earth's atmosphere 3.5 billions years ago and created stunning auroras, scientists said.

Scientists have long thought that Mars' small magnetic field left it vulnerable to the solar wind, a stream of charged particles emitted by the Sun that interacts with Earth's magnetic field and atmosphere, and forms the auroras on Earth.
