The Exoplanet Explosion

The first six weeks of scientific data returned by Kepler has already turned up five exoplanets, with many more candidates waiting to be studied. (credit: NASA)

From The Space Review:

Fifteen years ago, there were virtually no known planets beyond the (then nine) planets in our own solar system: just a few found by chance orbiting a pulsar. Then, in late 1995 and 1996, came the initial discovery of planets orbiting main sequence stars like the Sun. That slow trickle of discoveries became a steady stream as astronomers refined their instruments and techniques, as well as increased both the number of stars studied and their period of time observed. By the beginning of 2010 astronomers reported finding over 400 such extrasolar planets, or exoplanets.

Cocaine Found In Shuttle Work Area, NASA Says

Workers align the space shuttle Discovery's thrusters in Orbiter Processing Facility Bay 3 at NASA's Kennedy Space Center in December 2009. A small amount of cocaine was found in a restricted area of the facility on Wednesday, NASA said. NASA

From MSNBC/Space.com:

NASA says workers face drug tests; no impact on flights expected.

NASA is investigating how a small amount of cocaine ended up in a space shuttle hangar at the agency's Florida spaceport.

A bag containing the cocaine residue was discovered in the space shuttle Discovery's hangar at NASA's Kennedy Space Center in Cape Canaveral, Fla. The hangar, known as the Orbiter Processing Facility, is a restricted zone for shuttle workers only.

From New Scientist:

A new class of star may recreate the conditions of the big bang in its incredibly dense core.

Pack matter tightly enough and gravity will cause it to implode into a black hole. Neutron stars were once thought to be the densest form of matter that could resist such a collapse. More recently, physicists have argued that some supernovae may leave behind even denser quark stars, in which neutrons dissolve into their constituent quarks.

The 7.0-magnitude earthquake that devastated Haiti was long predicted by one group of geophysicists. Could the tragedy have been prevented?

On January 12, around dinnertime, a 7.0-magnitude earthquake struck Haiti, decimating the island nation and leaving hundreds of thousands presumed dead. A rescue effort is underway now, but as government officials and rescue agencies sort through the rubble, it is worth asking: Could this tragedy have been prevented?

From Cosmos:

Some scientists are convinced life is common in the universe, but intelligence rare. As for how long civilisations last - and stay detectable - few are willing to hazard a guess.

Two young physicists at Cornell University in upstate New York, Philip Morrison and Giuseppe Cocconi, had long been interested in gamma rays. One spring day in 1959, Cocconi posed an intriguing question: wouldn’t gamma rays be perfect for communication between the stars?

The discussion that followed led to a two-page article in the British journal Nature entitled “Searching for interstellar communications”. Sandwiched between a paper on the electronic prediction of swarming in bees and one on metabolic changes induced in red blood cells by X-rays, the duo argued that if advanced extraterrestrial civilisations existed, and wanted to communicate, they would likely use radio.

Haiti Earthquake Science: What Caused The Disaster

From The Live Science:

The major earthquake that struck Haiti Tuesday may have shocked a region unaccustomed to such temblors, but the devastating quake was not unusual in that it was caused by the same forces that generate earthquakes the world over. In this case, the shaking was triggered by much the same mechanism that shakes cities along California's San Andreas fault.

The 7.0-magnitude Haiti earthquake would be a strong, potentially destructive earthquake anywhere, but it is an unusually strong event for Haiti, with even more potential destructive impact because of the weak infrastructure of the impoverished nation.

Google Is Not The Only Internet Site Attacked By China

Google China Cyberattack Part Of Spy Campaign -- MSNBC/Washington Post

Dozens of companies, human rights groups targeted in sophisticated strike.

Computer attacks on Google that the search giant said originated in China were part of a concerted political and corporate espionage effort that exploited security flaws in e-mail attachments to sneak into the networks of major financial, defense and technology companies and research institutions in the United States, security experts said.

At least 34 companies — including Yahoo, Symantec, Adobe, Northrop Grumman and Dow Chemical — were attacked, according to congressional and industry sources. Google, which disclosed on Tuesday that hackers had penetrated the Gmail accounts of Chinese human rights advocates in the United States, Europe and China, threatened to shutter its operations in the country as a result.

From MSNBC/Cosmic Log:

Do rocks from Mars bear the tiny fossilized signs of life? Scientists who think so say they'll subject meteorites from the Red Planet to a new round of high-tech tests in hopes of adding to their evidence.

For years, only one meteorite has figured in the controversy: ALH84001, a rock that was blasted away from Mars 16 million years ago, floated through space and fell through Earth's atmosphere onto Antarctica about 13,000 years ago. Scientists reported in 1996 that the rock contained microscopic structures that looked like "nano-fossils," but skeptics said the structures could have been created by chemical rather than biological reactions.

How Winning Can Mean Losing In Poker And Life

Karen Bleier / AFP / Getty

From Time Magazine:

You can learn a lot about gambling if you're willing to analyze 27 million hands of online poker. Don't have time for that? No worries; sociology doctoral student Kyle Siler of Cornell University has done it for you. His counterintuitive message: the more hands you win, the more money you're likely to lose — and this has implications that go well beyond a hand of cards.

Siler, whose work was published in December in the online edition of the Journal of Gambling Studies and will appear later this year in the print edition, was not interested in poker alone but in the larger idea of how humans handle risk, reward and variable payoffs. Few things offer a better way of quantifying that than gambling — and few gambling dens offer a richer pool of data than the Internet, where millions of people can play at once and transactions are easy to observe and record.

OLED Could Be Apple Tablet’s Secret Solution For E-Reading

From Gadget Lab:

An OLED display would be a pricey, but perfect, screen for e-book reading on a tablet, like the one Apple is rumored to be announcing later this month.

OLEDs are serious power drainers, but if Apple were to implement a reading mode with a black background and light-colored text, then an OLED screen would consume far less energy. That’s because OLEDs consume power differently than LCDs; they only use power when pixels are turned on. That means blacks won’t consume any energy, and such a reading mode would substantially preserve battery life, an analyst told Wired.com.

From New Scientist:

NASA is feeling the pinch in its plutonium supplies.

Many spacecraft are powered by the radioactive decay of plutonium-238, but the US no longer produces the material. Instead, NASA relies on its shrinking stockpile, topped up with purchases from Russia.

Previous estimates suggested the decline would not affect solar-system exploration until after 2020, but NASA is already tightening its belt. Candidates for NASA's next "New Frontiers" mission, which aims to launch an exploratory spacecraft by 2018, will not be allowed to rely on plutonium for power, effectively limiting the candidate probes to solar power only.

A New Theory On Why The Sun Never Swallowed The Earth

Illustration by Denis Scott / Corbis

From Time Magazine:

When astronomers began spotting planets around distant stars in the mid-1990s, they were baffled. Many of these early discoveries involved worlds as big as Jupiter or even bigger — but they orbited their stars so tightly that their "years" were just days long. Nobody could imagine how a Jupiter or anything like it could form in such a hostile location, where the radiation of the parent star would have pushed the light gas — which makes up most of such a planet's mass — out to the farthest reaches of the solar system before it could ever coalesce.

Breezy Does It: How Wind Turbines Work

The great advantage of wind is that it is a free fuel, unlike gas, coal or oil. Britain is also a windy place, making supply relatively secure. GETTY IMAGES

From The Independent:

Wind farms generate electricity by capturing the kinetic energy of moving air.

The three blades of each turbine turn on a horizontal axis in the wind and the movement of this drive shaft spins an electricity generator, usually via a gearbox, so that power can be fed into the National Grid.

The wind farms being planned for sites off the coast of Britain will include some of the biggest wind generators ever built, with blades up to 60m long. These offshore wind generators will stand in water that is up to 30m deep and will be up to 220m tall from the base of their foundations to the tips of the turbine blades, about 40m taller than the "Gherkin" skyscraper in London.

A ban on Microsoft selling certain versions of its flagship products Word and Office has begun.

The software firm was made to change elements of the software by US courts after a patent dispute with Canadian firm i4i.

Microsoft said that it had complied with the court's ruling and would now offer "revised software" in the US.

The court ruling means that Microsoft must also pay i4i damages of $290m (£182m).

Remembering The First Hydrogen Bomb Test

From Wired Science:

The long-distance scientific recordings of the blast wave from the first hydrogen bomb test have been rediscovered in a formerly classified safe at Columbia University.

On November 1, 1952, physicists created the second fusion explosion the solar system has ever known. The first occurred around 4.5 billion years ago and ignited the ongoing fusion reaction in the sun. The second, the Ivy Mike experiment, was shorter lived and detonated on an atoll in the South Pacific. This 10-megaton blast was five times more powerful than all the explosives used in World War II combined, including the nuclear-fission bombs dropped on Hiroshima and Nagasaki.

From The National Geographic:

While relatively few people were looking, an unusual eclipse darkened New Year's Day.

On January 1 a giant space object blotted out our view of Epsilon Aurigae, a yellow supergiant star about 2,000 light-years from Earth. Based on studies of Epsilon Aurigae's previous eclipses, astronomers expect the star won't fully regain its bright shine until early 2011.

Overwhelmed With Data Feeds, Military Turns To NFL Broadcast Tricks For Highlighting Drone Targets

Analyzing Targets Keeping watch on imagery intelligence.

From Popular Science:

War is no game, but it could learn a trick or two from football.

A growing swarm of drones keep watch on the battlefield, but military analysts struggle to watch every second of live surveillance footage so that they can quickly pass on warnings about ambushes or possible targets to warfighters. Now the U.S. military has turned to ESPN and Fox Sports to learn how to quickly identify and transmit the video highlights, the New York Times reports.

The Coming Water Wars?

"Water: The Epic Struggle For Wealth, Power, And Civilization:" Water As The New Oil -- Seattle Times

Author Steven Solomon's "Water: The Epic Struggle for Wealth, Power, and Civilization" documents the hunt throughout history to find sources of clean water, a task likely to become more fraught with conflict in the coming age of water scarcity.

There's a slick catchphrase in the air these days — "Water is the new oil" — that author Steven Solomon and others use when referencing water's newfound significance on today's geopolitical stage.

But if Solomon's outstanding survey, "Water: The Epic Struggle for Wealth, Power, and Civilization," reveals anything, it is that oil, for maybe a century or so, was actually the new water, and now water has simply returned to the primacy it has always held throughout history.

In detailed but highly readable fashion, economics journalist Solomon ("Confidence Game," 1995) works through each major civilization — the Mesopotamians, the Egyptians, the early Romans, China, India, Islam, northern Europe, the New World — and shows the profound water challenges each faced and overcame in advancing human aspirations.

My Comment: This book is on my "to read" list. For the past few years I have been commenting in this blog on the history of wars over water, and on how future wars may revolve on the scarcity of clean water. From what I have read in the preamble to this book .... author Steven Solomon is hitting all the bases.

'Fossil' Fireballs from Supernovae Discovere By Suzaku Observatory

In the supernova remnant W49B, Suzaku found another fossil fireball. It detected X-rays produced when heavily ionized iron atoms recapture an electron.

From Science Daily:

ScienceDaily (Jan. 11, 2010) — Studies of two supernova remnants using the Japan-U.S. Suzaku observatory have revealed never-before-seen embers of the high-temperature fireballs that immediately followed the explosions. Even after thousands of years, gas within these stellar wrecks retain the imprint of temperatures 10,000 times hotter than the sun's surface.
