Opportunities Missed In Preparing For Gustav -- SciTech Blog (CNN)

If there were a Nobel Prize for “I told you so” it might go to Louisiana State University Professor Ivor van Heerden. He warned of the catastrophic consequences a major hurricane would have on New Orleans long before Hurricane Katrina.

And as Hurricane Gustav approaches, he says there were many lost opportunities to strengthen the region’s defenses in the three years since Katrina and Rita.

Among them:
*state and federal officials could have done a lot more to assess the weak links in the levee system, from New Orleans to Morgan City, Louisiana.
*more of an effort should have been made to repair damaged areas on levees. In many places, he said, there is bare soil, no grass at all on the levees.
*both before and after Katrina, he said the Army Corps of Engineers has not allowed enough outside experts to work with them to make improvements

Google Earth To License New Satellite Imagery -- Zdnet

Google has agreed to license imagery for their mapping products from a satellite due to launch on September 4th. This new satellite can take detailed imagery for an area the size of New Mexico in one day. What does that mean? Well, you could get high resolution pan-sharpened imagery for the entire country in around 30 days. Impressive.

The level of detail will be approximately 50cm per pixel — that’s just under 20 inches. If you want to see what that looks like, take a look at this. Imagine having a Google Maps/Earth content that is this detailed, 100% complete and updated once a month — that’s powerful stuff.

Lines and Bubbles and Bars, Oh My! New Ways
to Sift Data -- New York Times


PEOPLE share their videos on YouTube and their photos at Flickr. Now they can share more technical types of displays: graphs, charts and other visuals they create to help them analyze data buried in spreadsheets, tables or text.

At an experimental Web site, Many Eyes, (www.many-eyes.com), users can upload the data they want to visualize, then try sophisticated tools to generate interactive displays. These might range from maps of relationships in the New Testament to a display of the comparative frequency of words used in speeches by Senators Hillary Rodham Clinton and Barack Obama.

The site was created by scientists at the Watson Research Center of I.B.M. in Cambridge, Mass., to help people publish and discuss graphics in a group. Those who register at the site can comment on one another’s work, perhaps visualizing the same information with different tools and discovering unexpected patterns in the data.

Scientists Fear Impact Of Asian Pollutants On U.S.
-- Yahoo News/McClatchy


WASHINGTON — From 500 miles in space, satellites track brown clouds of dust, soot and other toxic pollutants from China and elsewhere in Asia as they stream across the Pacific and take dead aim at the western U.S.

A fleet of tiny, specially equipped unmanned aerial vehicles, launched from an island in the East China Sea 700 or so miles downwind of Beijing , are flying through the projected paths of the pollution taking chemical samples and recording temperatures, humidity levels and sunlight intensity in the clouds of smog.

On the summit of 9,000-foot Mt. Bachelor in central Oregon and near sea level at Cheeka Peak on Washington state's Olympic Peninsula , monitors track the pollution as it arrives in America.

Gustav Headed For Current That Fuels
Big Storms -- Yahoo News/AP

WASHINGTON - The difference between a monster and a wimp for Gulf of Mexico hurricanes often comes down to a small patch of warm deep water that's easy to miss. It's called the Loop Current, and hurricane trackers say Gustav is headed right for it, reminiscent of Katrina.

Gustav is likely to reach this current late Saturday, experts say. What happens next will be crucial, maybe deadly.

If Gustav hits the Loop Current and lingers in that hot spot, watch out. If the storm misses it or zips through the current, then Gustav probably won't be much of a name to remember.

The meandering Loop Current, located in the southeastern gulf, provides loads of hurricane fuel. It was a key stopover for nearly all the Gulf Coast killers of the past, including Katrina and Camille, said Florida International University professor Hugh Willoughby, former director of the government's hurricane research division.

The World Is Now Flowing Around The U.S.

Internet Traffic Begins To Bypass The U.S. -- New York Times

SAN FRANCISCO — The era of the American Internet is ending.

Invented by American computer scientists during the 1970s, the Internet has been embraced around the globe. During the network’s first three decades, most Internet traffic flowed through the United States. In many cases, data sent between two locations within a given country also passed through the United States.

Engineers who help run the Internet said that it would have been impossible for the United States to maintain its hegemony over the long run because of the very nature of the Internet; it has no central point of control.

And now, the balance of power is shifting. Data is increasingly flowing around the United States, which may have intelligence — and conceivably military — consequences.

How Strong Can A Hurricane Get?

Image of Category 5 Hurricane Katrina taken by NASA’s Terra satellite at 1:00 p.m. EDT on August 28, 2005, the day before it flooded New Orleans. NASA image courtesy of MODIS Rapid Response Team at Goddard Space Flight Center.

From Live Science:

Hurricane Gustav, churning toward the Gulf Coast now, has a small chance of becoming a Category 5 storm before it makes landfall, according to the National Hurricane Center. That would put its winds at 156 mph or stronger. Such winds would devastate most buildings and trees in the storms path. Little would be left standing.

There is no such thing as a Category 6 storm, in part because once winds reach Category 5 status, it doesn't matter what you call it, it's really, really bad.

Category 5 on the Saffir-Simpson hurricane scale has no upper bound, on paper. But in theory, winds from a powerful hurricane could blow the scale out of the water, scientists say.

Oil Companies Getting Ready For Hurricane Gustav

Katrina Lessons in Mind, Oil Companies Prep
Platforms for Gustav -- Popular Mechanics


HOUSTON — When Hurricane Katrina roared through the Gulf of Mexico three years ago, it ripped the drilling rig atop Royal Dutch Shell's Mars platform from its clamps and slammed it back onto the top deck in a crumpled pile of steel.

But the company's Ursa platform, just 7 miles to the east, emerged unscathed as 80-foot waves and 175-mph winds hammered the region.

A storm doesn't necessarily wreak havoc on all installations it touches, said Peter Marshall, a retired Shell engineer and consultant, as operators continued preparations Thursday for Tropical Storm Gustav's expected move into the energy-rich gulf.

Some structures may get the brunt while others don't, or a storm may expose an unanticipated weakness.

In the case of the two Shell structures, the platforms themselves withstood the storm, Marshall said. The damage at Mars stemmed from clamps and bolts that failed to hold its drilling rig to beams. The repaired rig now has stronger clamps.

Converting One Cell Into Another


Going From One Cell Type to Another Without
Using Stem Cells -- Wired Science


In an unprecedented flourish of genetic alchemy, scientists used a virus to coax one type of cell to become another, without the intermediate stem cell step.

The research, conducted with cells from the pancreas, could soon be used to treat people with diabetes -- but its long-term impacts could be even greater.

"This represents a parallel approach for how to make cells in regenerative medicine," said Douglas Melton, co-director of the Harvard Stem Cell Institute. "And now that it's shown that you can turn one of your cells into another, it makes you think of what other cells you'd like to convert."

Scientists Close In On Mass Killer Of Life On Earth


From McClatchy:

WASHINGTON — It was the greatest mass murder of all time — poison everywhere! billions slain! — but the killer or killers have never been positively identified.

An estimated 95 percent of all marine species and up to 85 percent of land creatures perished, according to Peter Ward, a paleobiologist at the University of Washington in Seattle.

Scientists call it "The Great Dying." Life took millions of years to recover.

Scientific sleuths, however, now think they're making progress toward pinning down what caused the extinction of most plants and animals on Earth some 251 million years ago.

Living Forever

Babylonian Epic of Gilgamesh

Secrets Of Immortality Could Be Tantalisingly
Close -- The Telegraph


The most extensive survey of anti ageing research ever conducted has concluded that a longevity pill to "cure" ageing remains a possibility.
- Antiageing drug shows promise in first human test
- New target for longevity pills
- Scientists find elixir of eternal life - in a worm

However, the current state of knowledge is inadequate to be sure.

The inevitability of ageing and death has fascinated humanity for millennia and is at the heart of the most ancient known mythology, the Babylonian Epic of Gilgamesh, where a Sumerian king tells of his desire to escape death and his ultimate realisation that only through lasting works of culture can he achieve immortality.

Many scientists work on mechanisms that determine lifespan in "model organisms" such as worms, flies and mice but there have been persistent doubts about whether this work is really relevant to humans and whether we may yet manipulate lifespan with drugs, genetic knowledge or fine-tuning diet.

Popular Science has a rundown of the top future pills that may one day change your life. Launch it here.

Video: Oil Addiction And Biofuel Dangers Simplified

From Autobloggreen:

There's a new video from Good Magazine that explains the viewpoint of those who believe that using crops for biofuels isn't good for the environment with simple and clear language. The short clip references articles from newspapers such as the LA Times and the NY Times, as well as official agencies like the DOE. The video outlines the reasons as follows: if high demand and fear of the short of supply make oil prices rise, then biofuel producers use feedstock to make their biofuels. Then, the high oil prices and the shortage of feedstocks make food more expensive, giving us the global crisis we've seen recently. If you think that the light relief from recent cuts in oil prices is enough to keep us saved, keep this video in mind. Watch it after the jump.

The Sad Truth About Wind Power

The Maple Ridge Wind farm near Lowville, N.Y. It has been forced to
shut down when regional electric lines become congested.

Wind Energy Bumps Into Power Grid’s Limits -- New York Times

When the builders of the Maple Ridge Wind farm spent $320 million to put nearly 200 wind turbines in upstate New York, the idea was to get paid for producing electricity. But at times, regional electric lines have been so congested that Maple Ridge has been forced to shut down even with a brisk wind blowing.

That is a symptom of a broad national problem. Expansive dreams about renewable energy, like Al Gore’s hope of replacing all fossil fuels in a decade, are bumping up against the reality of a power grid that cannot handle the new demands.

The dirty secret of clean energy is that while generating it is getting easier, moving it to market is not.

Arctic Sea Ice Nears Record Low

north coast of Ellesmere Island in Canada. Sam Soja / AP


From Times Magazine:

Arctic Ocean sea ice has melted to the second lowest minimum since satellite observations began, according to scientists at the National Snow and Ice Data Center.

Sea ice melt recorded on Monday exceeded the low recorded in 2005, which had held second place.

With several weeks left in the melt season, ice in summer 2008 has a chance to diminish below the record low set last year, according to scientists at the National Snow and Ice Data Center.

Environmental groups said the ice melt was another alarm bell warning of global warming.

"It's an unfortunate sign that climate change is coming rapidly to the Arctic and that we really need to address the issue of global warming on a national level," said Christopher Krenz, Arctic project manager for Oceana.

At Conference On The Risks To Earth, Few Are Optimistic


From The New York Times:

ERICE, Sicily — This ancient hilltop town, rife with Roman, Greek, Norman and other influences, is hosting a very modern gathering: a conference on global risks like cyberterrorism, climate change, nuclear weapons and the world’s lagging energy supply.

More than 120 scientists, engineers, analysts and economists from 30 countries were hunkered down here for the 40th annual conference on “planetary emergencies.” The term was coined by Dr. Antonino Zichichi, a native son and a theoretical physicist who has made Erice a hub for experts to discuss persistent, and potentially catastrophic, global challenges.

The participants were not particularly optimistic. They presented data showing that the boom in biofuels was depleting Southeast Asian rain forests, that “bot herders” — computer hackers for hire — were hijacking millions of computers, and that the lack of progress over handling nuclear waste was both hampering the revival of nuclear energy and adding to terrorism risks.

This Is So Cool

Solar Plane Makes Record Flight -- BBC News

A UK-built solar-powered plane has set an unofficial world endurance record for a flight by an unmanned aircraft.

The Zephyr-6, as it is known, stayed aloft for more than three days, running through the night on batteries it had recharged in sunlight.

The flight was a demonstration for the US military, which is looking for new types of technology to support its troops on the ground.

Craft like Zephyr might make ideal platforms for reconnaissance.

They could also be used to relay battlefield communications.

Chris Kelleher, from UK defence and research firm QinetiQ, said Unmanned Aerial Vehicles (UAVs) offer advantages over traditional aircraft and even satellites.

New Rays Of Hope For Solar Power’s
Future -- Christian Science Monitor


High cost of fossil fuel and advanced technology improve this energy source’s prospects.

From five miles away, the Nevada Solar One power plant seems a mirage, a silver lake amid waves of 110 degree F. desert heat. Driving nearer, the rippling image morphs into a sea of mirrors angled to the sun.

As the first commercial “concentrating solar power” or CSP plant built in 17 years, Nevada Solar One marks the reemergence and updating of a decades-old technology that could play a large new role in US power production, many observers say.

“Concentrating solar is pretty hot right now,” says Mark Mehos, program manager for CSP at the National Renewable Energy Laboratory in Golden, Co. “Costs look pretty good compared to natural gas [power]. Public policy, climate concern, and new technology are driving it, too.”
