From Science Daily:

ScienceDaily (Nov. 16, 2008) — Cities from Beijing to New Delhi are getting darker, glaciers in ranges like the Himalayas are melting faster and weather systems becoming more extreme, in part, due to the combined effects of man-made Atmospheric Brown Clouds (ABCs) and greenhouse gases in the atmosphere.

These are among the conclusions of scientists studying a more than three km-thick layer of soot and other manmade particles that stretches from the Arabian Peninsula to China and the western Pacific Ocean.

The Movies -- The Best Fictional Doomsday Devices

The Death Star (Star Wars)

From Wired News:

America's love affair with the doomsday device is a turbulent one. First popularized in comic books and James Bond movies, then lampooned by Austin Powers, we love them because their ridiculousness makes us feel safe — like the exhilarating false danger of a roller coaster.

Now heightened audience cynicism has forced world-ending devices into the realm of camp, and except for a new breed of superhero movies, they've largely been replaced by natural disasters or apocalyptic sci-fi scenarios in Hollywood films.

Variable Electric Generator Improves Wind Power Efficiency

(Photo form Talking Tourism)

From Future Pundit:

An interesting article in MIT's Technology Review reports on a generator for wind turbines that can harvest electric power over a wider range of wind speeds.

ExRo Technologies, a startup based in Vancouver, BC, has developed a new kind of generator that's well suited to harvesting energy from wind. It could lower the cost of wind turbines while increasing their power output by 50 percent.

The new generator runs efficiently over a wider range of conditions than conventional generators do. When the shaft running through an ordinary generator is turning at the optimal rate, more than 90 percent of its energy can be converted into electricity. But if it speeds up or slows down, the generator's efficiency drops dramatically.

From The Christian Science Monitor:

‘Boot camp’ in Maine teaches them how to get their message across in five minutes.

You’ve got a world-changing idea. And a passion to make it happen.

That’s good. But you need a third element: The ability to “pitch” your idea to venture capitalists and others who can help turn your dream into reality.

Budding business tycoons or Hollywood script writers know the importance of marketing themselves and their projects. But those in the nonprofit world, whose goal is altruistic, may never have thought about how to put a dazzling sheen on their quick “elevator pitch.”

Learning what goes into a perfect pitch was just one of the practical skills taught to a group of up-and-coming “social innovators” last month at the 12th annual PopTech conference in Camden, Maine.

Marine Dead Zones Set To Expand Rapidly

Oxygen content of the world's oceans. Regions with low oxygen are shown in red. IFM-GEOMAR

From Nature:

Rising levels of carbon dioxide could increase the volume of oxygen-depleted 'dead zones' in tropical oceans by as much as 50% before the end of the century — with dire consequences for the health of ecosystems in some of the world's most productive fishing grounds.

At depths between several tens and hundreds of metres, large parts of the tropical oceans are poorly supplied with dissolved oxygen, and are therefore hostile to most marine life. Scientists suspect that these zones are sensitive to climate change, but previous studies have arrived at conflicting conclusions regarding exactly how and why a more CO2-rich world affects oceanic oxygen content.

Telcos: Don't Mess Up The Internet With Regulation

From CNET News:

WASHINGTON--Representatives from industry, government, and advocacy groups agreed on Thursday that the Internet needs to be open and widely available throughout the United States. The question is how to get there.

A newly emboldened Democratic Congress is sure to have a long wish list, including new Internet regulations that corporations believe are unwise or unnecessary. Net neutrality regulations are one possibility, as is broadband and spectrum legislation. But it's unclear where the money to pay for sweeping new projects will come from--neither tax increases nor deficit spending on tech seem that likely when a Wall Street and Detroit bailout are center stage--so today's laws and regulations may end up being extended by default.

From FOX News:

It's more than twice as old as the Pyramids, or even the written word. When it was built, saber-toothed tigers and woolly mammoths still roamed, and the Ice Age had just ended.

The elaborate temple at Gobelki Tepe in southeastern Turkey, near the Syrian border, is staggeringly ancient: 11,500 years old, from a time just before humans learned to farm grains and domesticate animals.

According to the German archaeologist in charge of excavations at the site, it might be the birthplace of agriculture, of organized religion — of civilization itself.

"This is the first human-built holy place," Klaus Schmidt of the German Archaeological Institute says in the November issue of Smithsonian magazine.

Artificial Diamonds - Now Available in Extra Large

From The New Scientist:

Diamonds are a girl's best friend, they say - and soon they could be every girl's best friend.

A team in the US has brought the world one step closer to cheap, mass-produced, perfect diamonds. The improvement also means there is no theoretical limit on the size of diamonds that can be grown in the lab.

A team led by Russell Hemley, of the Carnegie Institute of Washington, makes diamonds by chemical vapour deposition (CVD), where carbon atoms in a gas are deposited on a surface to produce diamond crystals.

The CVD process produces rapid diamond growth, but impurities from the gas are absorbed and the diamonds take on a brownish tint.

These defects can be purged by a costly high-pressure, high-temperature treatment called annealing. However, only relatively small diamonds can be produced this way: the largest so far being a 34-carat yellow diamond about 1 centimetre wide.

From Science Daily:

ScienceDaily (Nov. 15, 2008) — An unusual microorganism discovered in the open ocean may force scientists to rethink their understanding of how carbon and nitrogen cycle through ocean ecosystems. A research team led by Jonathan Zehr, professor of ocean sciences at the University of California, Santa Cruz, characterized the new microbe by analyzing its genetic material, even though researchers have not been able to grow it in the laboratory.

Zehr said the newly described organism seems to be an atypical member of the cyanobacteria, a group of photosynthetic bacteria formerly known as blue-green algae. Unlike all other known free-living cyanobacteria, this one lacks some of the genes needed to carry out photosynthesis, the process by which plants use light energy to make sugars out of carbon dioxide and water.

Grandma Is Better Babysitter Than Mom

From Live Science:

Common wisdom might suggest that because of their age, grandmothers are inappropriate caretakers for infants and children.

Sure, they might have years and years of parenting experience from bringing up their own children (and they must be OK parents because their children obviously lived long enough to have children) but people over 50 simply can't run as fast or react as quickly as young parents. And they presumably tire more quickly and must want to take a load off even more often than the most exhausted parent.

The Consequence Of A Failed Electricity Policy

Get Ready For Rolling Brownouts And Huge Hikes
In Electricity Prices -- Q and O

Forbes warns us:

If you think runaway oil prices are upsetting, just wait for what's in store for electricity. Similar forces are in play. Demand is rising fast; supply is not. The cost to get coal and natural gas out of the ground is going up, and to that expense must be added the cost of the carbon permits that Congress and the presidential candidates are contemplating. Environmentalists are getting power plants scotched. China is sucking up energy. Leave such dynamics in play long enough, and price spikes in electricity follow. But that's just the beginning. We may be facing brownouts (voltage reductions) and even rolling blackouts.

Price shocks are already a part of the system says the article:

Price shocks are already occurring. In May, long before peak summer demand, the wholesale price of juice jumped twofold in Texas, to $4 per kilowatt-hour, 25 times the average retail rate in the country. Prices exceeded the allowed rate of $2 for seven days and threatened the viability of power resellers who contracted to deliver cheap rates to consumers. New Yorkers may suffer a summer of price discontent if regulators are right about peak wholesale prices jumping by up to 90%.

CHICAGO (Reuters) – Bleach has been killing germs for more than 200 years but U.S. scientists have just figured out how the cleaner does its dirty work.

It seems that hypochlorous acid, the active ingredient in bleach, attacks proteins in bacteria, causing them to clump up much like an egg that has been boiled, a team at the University of Michigan reported in the journal Cell on Thursday.

The discovery, which may better explain how humans fight off infections, came quite by accident.

From Popsci:

Nearly four years after a series of disastrous tsunami waves struck coastlines bordering the Indian Ocean, a new Tsunami Early Warning System is up and running in Indonesia. Using a series of buoys linked to detectors that sit on the ocean floor, the new high-tech warning system will be able to detect an undersea earthquake and predict within minutes whether it will cause a tsunami.

Catastrophic tsunamis result from undersea earthquakes or landslides, and when earthquake-generated tsunamis occur off the coast of Indonesia, the waves can reach the coast in as little as twenty minutes -- leaving little to no warning time for residents in high-risk areas. The 2004 tsunami reached the province of Banda Aceh just a quarter of an hour after a magnitude-9.1 earthquake struck, resulting in 140,000 deaths in that region alone.

UN: Clouds Of Pollution Threaten Glaciers, Health

From Myway/AP:

BEIJING (AP) - A dirty brown haze sometimes more than a mile thick is darkening skies not only over vast areas of Asia, but also in the Middle East, southern Africa and the Amazon Basin, changing weather patterns around the world and threatening health and food supplies, the U.N. reported Thursday.

The huge smog-like plumes, caused mainly by the burning of fossil fuels and firewood, are known as "atmospheric brown clouds."

Google Flu Trends uses the tendency of people to seek online help for their health problems.

By tracking searches for terms such as 'cough', 'fever' and 'aches and pains' it claims to be able to accurately estimate where flu is circulating.

Google tested the idea in nine regions of the US and found it could accurately predict flu outbreaks between seven and 14 days earlier than the federal centres for disease control and prevention.

Google hopes the idea could also be used to help track other diseases. Flu Trends is limited to the US.

How Much Can We Blame DNA For Who We Are?

Now it turns out that genes, per se, are simply too feeble to accept responsibility for much of anything. By the traditional definition, genes are those lineups of DNA letters that serve as instructions for piecing together the body's proteins, and, I'm sorry, but the closer we look, the less instructive they seem, less a "blueprint for life" than one of those disappointing two-page Basic Setup booklets that comes with your computer, tells you where to plug it in and then directs you to a Web site for more information.

Global Warming Link To Amphibian Declines In Doubt

From E! Science News:

Evidence that global warming is causing the worldwide declines of amphibians may not be as conclusive as previously thought, according to biologists. The findings, which contradict two widely held views, could help reveal what is killing the frogs and toads and aid in their conservation. "We are currently in the midst of a sixth mass extinction event," said Peter Hudson, the Willaman professor of biology at Penn State and co-author of the research study. "And amphibians are bearing the brunt of the problem."

Studies suggest that more than 32 percent of amphibian species are threatened and more than 43 percent face a steep decline in numbers.

Much of the massive declines associated with amphibians appear to be centered in places such as Central America and Australia, said Hudson. "It appears to be linked to a chytrid fungus -- Batrachochytrium dendrobatidis (Bd) -- which we did not know affected frogs," he added.

From Discovery:

Nov. 12, 2008 -- Generating wind power at sea may disturb ocean currents and marine ecosystems, according to a new study.

Offshore wind farms are common in Europe; Denmark, The Netherlands, and the United Kingdom all have several active installations. Wind power in the United States is currently confined to dry land, but three installations are planned off the coast of New Jersey, Rhode Island, and Delaware, totaling about 1,500 megawatts of generating capacity.

Extracting energy from wind changes regional air currents, which can in turn affect how the nearby ocean circulates, according to Goran Brostrom of the Norwegian Meteorological Institute in Oslo.

Two-Fifths Of Earth's Population at Risk

From Science Blog:

Vibrio cholerae. Cholera. One of the most aggressive water-borne infections, cholera can kill within 24 hours, and has caused seven pandemics in history. It occurs in over 60 countries worldwide. Currently, the World Health Organization(WHO) has warned that cholera is a serious risk in the Democratic Republic of Congo, where there have already been 1,000 cases since October. Of course, most Americans are unfamiliar with cholera since the last outbreak in the U.S. was in 1911. And I don't think any of us were around for that.

Cholera is a bacterial infection of the intestine that comes from consuming infected food or water. Symptoms begin with sever diarrhea and vomiting, which then lead to dehydration. Blood pressure falls, cramps develop in the legs and abdomen, and then body temperature drops as organ failure occurs. Not a pretty picture. There is hope however.

From Live Science:

Editor's Note: Each Wednesday LiveScience examines the viability of emerging energy technologies — the power of the future.

The ocean harbors abundant energy in the form of wind, waves and sun. All of these could be sampled on something called an Energy Island: a floating rig that drills for renewables instead of petroleum.

The concept is the brainchild of inventor Dominic Michaelis. He was originally unsatisfied with the slow progress in developing ocean thermal energy conversion (OTEC), a process in which cold water is pumped up from the deep ocean to generate electricity.

"Nothing new was happening with OTEC, so I thought why not bring other marine energy technologies on board?" Michaelis said.

A History Of Microsoft Windows

From Wired News:

Windows 1.0

The world's most ubiquitous operating system was not always so. The evolution of Windows was often uncertain and precarious. Its success was symbiotic with advancements in processor speed and memory capacity, and Microsoft relied heavily on third-party software to bridge the gap between concept and consumer. Tour the 23-year history of the Windows OS through these screenshots.

Left: Microsoft's first graphical user interface -- Windows 1.0 -- wasn't released until November 1985, nearly two years after Apple introduced the Mac. Due to legal issues with Apple, Gates couldn't include key features like overlapping windows and a trash can. Looking at it now, it's not surprising it was a flop. Windows 1.0 was more an extension of MS-DOS than its own operating system, but it did allow limited multitasking and mouse support.

Study Shows How Spammers Cash In

From BBC News:

Spammers are turning a profit despite only getting one response for every 12.5m e-mails they send, finds a study.

By hijacking a working spam network, US researchers have uncovered some of the economics of being a junk mailer.

The analysis suggests that such a tiny response rate means a big spam operation can turn over millions of pounds in profit every year.

It also suggests that spammers may be susceptible to attacks that make it more costly to send junk mail.

Taiwan Makes Fastest 60GHz Wireless System On A Chip, 100 Times Wifi Speed For Less Than $1

From The Next Big Future:

National Taiwan University announced their latest invention System on a Chip (SOC) yesterday, the smallest such product at the lowest cost and consuming the least electricity. The NTU research team claims that the transmission speed of the chip is 100 times as fast as WiFi and 350 times as fast as a 3.5G cell phone. Lee indicated that the chip size has been reduced to 0.5 millimeter, one-tenth of that of existing chips, and the cost is less than one-tenth of the traditional communication module and could be further lowered to only US$1. The SOC successfully combines RF Front-End Circuits and an antenna array to reach the highest transmission speed.

IBM To Help Build Broadband Network In Power Lines

From Yahoo News Finance/AP:

Broadband over power lines gets a needed endorsement from a big player in computing

NEW YORK (AP) -- IBM Corp. is throwing its considerable weight behind an idea that seemed to have faded: broadband Internet access delivered over ordinary power lines.

The technology has been around for decades, but most efforts to implement the idea on a broad scale have failed to live up to expectations.

Now, with somewhat scaled-back goals, improved technology, and a dose of low-interest federal loans, IBM is partnering with a small newcomer called International Broadband Electric Communications Inc. to try to make the idea work in rural communities that don't have other broadband options.
