An Operating System For The Cloud

Credit: Brian Stauffer

From Technology Review:

Google is developing a new computing platform equal to the Internet era. Should Microsoft be worried?

From early in their company's history, Google's founders, Larry Page and Sergey Brin, wanted to develop a computer operating system and browser.

They believed it would help make personal computing less expensive, because Google would give away the software free of charge. They wanted to shrug off 20 years of accumulated software history (what the information technology industry calls the "legacy") by building an OS and browser from scratch. Finally, they hoped the combined technology would be an alternative to Microsoft Windows and Internet Explorer, providing a new platform for developers to write Web applications and unleashing the creativity of programmers for the benefit of the masses.

Hole in the Earth

FROM LIVE SCIENCE

A meteorite that rocked the Sahara

A meteorite that rocked the Sahara desert over 300 million years ago left behind quite a scar that's been photographed before.

New satellite images released by NASA this week provide a closer view of the Aorounga Impact Crater in north-central Chad, one of the best preserved impact structures in the world.

The crater measures 10 miles (17 kilometers) across with a peak that is surrounded by a small sand-filled trough. This feature is surrounded by an even larger circular trough. Winds at the site blow from the northeast and sand dunes formed between the ridges are actively migrating to the southwest. Measuring 10 miles (17 kilometers) across,

Machismo Cuts Men's Lives Short

FROM: LIVE SCIENCE

Why they don't go


Tough guys who buy into ideals of masculinity are much less likely to seek preventive healthcare services, such as a prostate exam, compared with other men.

The new finding, based on survey data, reveals that such manly beliefs could help to explain the lower life expectancy of men compared with women.

In the United States in 2005, life expectancy for women averaged about 80 years, while for men it was about 75 years, according to the Centers for Disease Control and Prevention.

NOAA Lowers Hurricane Season Outlook

(Click Above Image to Enlarge)
While NOAA is lowering forecasts, the Accumulated Cyclone Energy (ACE) from FSU COAPS is also quite low. Ryan Maue’s Tropical web page at Florida State University has this graph that shows accumulated cyclone energy (ACE)

From Watts Up With That?

According to its August Atlantic hurricane season outlook, NOAA now expects a near- to below-normal Atlantic hurricane season, as the calming effects of El Niño continue to develop. But scientists say the season’s quiet start does not guarantee quiet times ahead. The season, which began June 1, is entering its historical peak period of August through October, when most storms form.

1 Million MPH Stars Move Through Galaxy

From FOX News/Space:

Stars in a distant galaxy move at stunning speeds — greater than 1 million mph, astronomers have revealed.

These hyperactive stars move at about twice the speed of our sun through the Milky Way, because their host galaxy is very massive, yet strangely compact. The scene, which has theorists baffled, is 11 billion light-years away. It is the first time motions of individual stars have been measured in a galaxy so distant.

While the stars' swiftness is notable, stars in other galaxies have been observed to travel at similarly high speeds. In those situations, it was usually because they were interlopers from outside, or circling close to a black hole.

Earth's Most Prominent Rainfall Feature Creeping Northward

From Science Daily:

ScienceDaily (Aug. 9, 2009) — The rain band near the equator that determines the supply of freshwater to nearly a billion people throughout the tropics and subtropics has been creeping north for more than 300 years, probably because of a warmer world, according to research published in the July issue of Nature Geoscience.

If the band continues to migrate at just less than a mile (1.4 kilometers) a year, which is the average for all the years it has been moving north, then some Pacific islands near the equator – even those that currently enjoy abundant rainfall – may be drier within decades and starved of freshwater by midcentury or sooner. The prospect of additional warming because of greenhouse gases means that situation could happen even sooner.

Why 'Willy' Could Never Be Free

Keiko in home waters. Credit: F. Ugarte/arc-pic.com

From Live Science:

In 1998, with much fanfare, a 20-year-old orca named Keiko took a one-way trip on an Air Force cargo plane from Oregon to Iceland. There, attended by dozens of biologists and trainers, and at a cost reportedly topping $20 million, the orca was gradually reintroduced to his native waters.

Keiko, of course, had starred in three "Free Willy" movies, which sparked a public campaign to free him after nineteen years in captivity.

But things didn’t quite turn out as planned.

A team of his former caretakers, led by Malene J. Simon of the Greenland Institute of Natural Resources in Nuuk, has analyzed logs of Keiko’s behavior and data from satellite tags recording his travels and dives. They point out that Keiko never managed to integrate with Icelandic orca pods and didn’t seem to do much diving or fishing. He spent two several-week-long stretches on his own at sea, but ultimately chose to return to human care.

From The BBC:

Scientists in the US have made a major advance in their understanding of so-called freak waves.

These monster waves present a major risk to ships and offshore platforms.

A computer simulation developed by oceanographers in the US could help locate where and when these "rogue" phenomena are most likely to occur.

The theoretical study shows that coastal areas with variations in water depth and strong currents are hot spots for freak waves.

The history of seafaring is littered with tales of rogue waves capable of rending ships asunder.

Hurricane Season 2009: Where Are All the Storms?

El Niño conditions over the Pacific Ocean have so far kept a lid on the 2009 Atlantic hurricane season, experts said in August 2009. But there's still plenty of time for a "monster" to form by season's end. Hurricane Andrew, seen above barreling toward Florida on August 24, 1992, also formed during an El Niño year. Andrew was the third most powerful hurricane to make U.S. landfall in recorded history. Photograph courtesy National Oceanic and Atmospheric Administration (NOAA)

From National Geographic:

Before the 2009 Atlantic hurricane season kicked off on June 1, forecasters were calling for 12 named storms, with about half developing into hurricanes.

Now, about two months into the season, zero storms have formed in the Atlantic.

That's because El Niño conditions over the Pacific Ocean have so far kept a lid on the 2009 hurricane season, experts say.

Still, meteorologists warn that a monster hurricane could be spawned before the season ends on November 30.

"Oases of favorable conditions" could exist in the Atlantic Basin long enough to allow a powerful storm to form, said Keith Blackwell, a meteorologist at the University of South Alabama's Coastal Weather Research Center in Mobile.

"It's very plausible that we still could get one or two intense hurricanes this year," Blackwell said. "And it only takes one to make it a bad season."

Virtual Computer Army Takes On The Botnets

From New Scientist:

MORE than 1 million virtual computers are set to provide insight into how networks of infected computers called botnets wreak havoc on the internet, as the Conficker worm did recently.

Ron Minnich and Don Rudish of Sandia National Laboratories in Livermore, California, crammed 250 independent linux "kernels" - the core system of a computer - onto each of 4400 networked Thunderbird machines, creating a total of over 1.1 million individual virtual computers.

While this network cannot mimic the internet's estimated 600 million computers, the duo hope to use it to study how a small number of machines can attack and bring down larger networks. They can also study, for example, why some botnets prefer to be small and others large.

How The Apple Tablet Could Ruin Computing

The Mythical Apple Tablet, Imagined: via Gizmodo

From Popular Science:

Hint: the mobile network providers are involved.

Though whispers of an Apple tablet device practically predate Australopithecus, this week they’ve reached a fever pitch. It’s been reported by several news outlets that the supposed iTablet will feature a 10-inch touchscreen, both Wi-Fi and 3G data, and a custom ARM processor. It’s already been priced at $800 and even greenlit by none other than His Majesty Steve Jobs for a September release. Not one iota of this has been officially confirmed, but the prospect of a Mac Tablet seems more within reach than ever before.

This is not a good thing. If an Apple tablet is ever actually released, we should all be very concerned for the future of what most of us take for granted today: our d

From The New York Times:

Karl and Dorsey Gude of East Lansing, Mich., can remember simpler mornings, not too long ago. They sat together and chatted as they ate breakfast. They read the newspaper and competed only with the television for the attention of their two teenage sons.

That was so last century. Today, Mr. Gude wakes at around 6 a.m. to check his work e-mail and his Facebook and Twitter accounts. The two boys, Cole and Erik, start each morning with text messages, video games and Facebook.

The new routine quickly became a source of conflict in the family, with Ms. Gude complaining that technology was eating into family time. But ultimately even she partially succumbed, cracking open her laptop after breakfast.

“Things that I thought were unacceptable a few years ago are now commonplace in my house,” she said, “like all four of us starting the day on four computers in four separate rooms.”

Why Are Flu Viruses Seasonal?

Heide Benser / Corbis

From Time Magazine:

U.S. health officials are bracing for a resurgence of the new H1N1/09 flu virus this fall, when the influenza season kicks into high gear with the resurgence of cold weather. By October, the government hopes to have 120 million doses of vaccine ready to fight the new virus, which is currently spreading around the world in the first pandemic in more than 40 years. Already, H1N1 is hitting the southern hemisphere hard: Argentina has recorded more than 160 deaths from H1N1, second most after the U.S. That's because it's winter in the southern hemisphere, and flu infections tend to spike during the fall and winter months in temperate countries.

Mapping The Globe's Soils

DIGITIZING DIRT: A global soil map could aid many areas of scientific research, including agriculture and climate modeling. ISTOCKPHOTO/ANTHONYROSENBERG

From Scientific American:

The lack of good information on global soils is hampering efforts to improve agriculture and combat climate change.

Long left in the dust by their peers in climate research, a small group of soil scientists is spearheading an effort to apply rigorous computer analysis to the ground beneath our feet.

Their goal: to produce a digital soil map of the entire world.

It is a daunting task. In many parts of the world, such as Africa and South Asia, knowledge of soil is sketchy at best, relying on fading paper maps. And without accurate soil information, it is difficult for planners to know where crops are best grown, or for climate modelers to predict how much carbon might be released from soil into the atmosphere.

Perseids Meteors To Light Up Skies Midweek

From San Francisco Chronicle:

The rocky debris from a wandering comet is filling the sky with shooting stars these nights, just as scribes in ancient China saw them 2,000 years ago and modern stargazers see them every August.

They are the Perseids, an annual meteor shower that makes a brilliant show wherever the viewing is good and the night sky is dark and clear.

This year, the bright streaks and occasional blazing fireballs of the meteors should reach their peak well before dawn Wednesday and after sunset that night.

But Tuesday night should offer a better view as the waning gibbous moon doesn't rise until 11 p.m and the sky will be darkest before the moonlight interferes, says Andrew Fraknoi, chairman of astronomy at Foothill College in Los Altos Hills.

Which Search Engine Do You Choose In The Blind Test?

From The Washington Post:

Have you tried out this blind search tool yet? It provides results from Google, Yahoo and Bing in three columns but doesn't tell you which column is which search engine. You then tell it which one you think shows the best results, and you then see which answers are from which engines. I keep choosing Yahoo as the best results.

A few search engine experts we've spoken with over the years say that users tend to think Google results are better just because they're from Google. If you take any search engine and put the logo on top, it tests better. So Yahoo results with a Google logo will always test better than, say, Google results with the Yahoo or Bing logo. People are just used to thinking about Google as the best search.

Seven astronauts climbed aboard NASA's space shuttle Discovery Friday for a vital drill to practice escaping from the spacecraft at the launch pad and go over plans for their late August blast off.

Clad in bright orange pressure suits, the astronauts strapped into Discovery at NASA's seaside Kennedy Space Center in Florida and rehearsed the last few hours before liftoff before scurrying out the shuttle's hatch to a set of baskets designed to zip down a 1,200-foot slide wire away from the launch pad in the event of an emergency.

The exercise capped a three-day training session to give Discovery's astronauts some hands-on experience with the spacecraft before their planned Aug. 25 launch to the International Space Station.

How Fast Can Sprinters Go?

From Live Science:

Well, maybe Usain Bolt was right after all. As discussed in our Physiology of Speed story, Bolt predicted he could run 100 meters in 9.54 seconds, lowering his own world record of 9.69 seconds.

Now, researchers from Tilburg University in the Netherlands say he could shave another 3/100ths of a second off and hit the tape at 9.51 seconds.

Using the "extreme value theory," Professor of Statistics John Einmahl and former student Sander Smeets have calculated the fastest possible times for men and women. Between 1991 and 2008, they chronicled the best times for 762 male sprinters and 469 female sprinters. They did not trust the data prior to 1991 as possibly being tainted by doping athletes (not that's its gotten much better since then.)

Extinction Hits 'Whole Families'

From The BBC:

Whole "chunks of life" are lost in extinction events, as related species vanish together, say scientists.

A study in the journal Science shows that extinctions tend to "cluster" on evolutionary lineages - wiping out species with a common ancestor.

The finding is based on an examination of past extinctions, but could help current conservation efforts.

Researchers say that this phenomenon can result in the loss of an entire branch of the "tree of life".

The message for modern conservation, say the authors, is that some groups are more vulnerable to extinction than others, and the focus should be on the lineages most at risk.

From Technology Review:

Research centers conceived to speed energy-related research are facing a tough battle in Congress.

A major effort to revamp research and development at the Department of Energy, which Energy Secretary Steven Chu says is critical to solving energy-related challenges, hangs in the balance as the Obama administration attempts to make its case to a skeptical Congress.

Last month, the House and Senate committees responsible for appropriating money to the Department of Energy shot down Chu's proposed "Energy Innovation Hubs," with the House killing funding for all but one of the eight proposed hubs and the Senate provisionally funding only three. The House committee called the hubs redundant and criticized the Department of Energy for a lack of planning and clear communication about them. Since then, the department has issued much more detailed accounts of the hubs, and the Obama administration has said it "strongly opposes" the committee's decision to cut the requested funds.

From Science Daily:

ScienceDaily (Aug. 7, 2009) — The first results are in from the Kepler orbiting observatory, the world's most powerful planet-searching telescope, and according to MIT planetary scientist Sara Seager they show that the instrument should have no trouble detecting "alien Earths" -- planets that are about the size of our own.

After its launch on March 6, Kepler began taking test data for engineering purposes. It was this engineering data, before the official inauguration of science operations, that produced the observatory's first published results, appearing this week in the journal Science. Seager, the Ellen Swallow Richards Associate Professor of Planetary Science and Associate Professor of Physics, is part of the Kepler science team but was not personally involved in this initial paper. She appeared at a NASA press conference on Thursday, Aug. 6, to comment on the significance of the results.

From Live Science:

Satellites have captured a snapshot of the Ganges delta, the world’s largest river delta and one of the most geographically turbulent spots in the world.

The interweaving network of streams that make up the Ganges Delta in South Asia is formed by the joining of three rivers – the Padma, Jamuna, and Meghna rivers. More than 100 million people (mostly Bangladeshi) call the delta home, relying mostly on rice, tea and other crops for subsistence. The region is also inhabited by around 1,000 endangered Bengal tigers.

From The New Scientist:

The world's most powerful particle smasher will restart in November at just half the energy the machine was designed to reach. But even at this level, the Large Hadron Collider has the potential to uncover exotic new physics, such as signs of hidden extra dimensions, physicists say.

The LHC is a new particle accelerator at the CERN laboratory near Geneva, Switzerland, designed to answer fundamental questions, such as what gives elementary particles their mass, by colliding particles at higher energies than ever achieved in a laboratory before.

From Watts Up With That:

Long debate ended over cause, demise of ice ages – may also help predict future.
CORVALLIS, Ore. – A team of researchers says it has largely put to rest a long debate on the underlying mechanism that has caused periodic ice ages on Earth for the past 2.5 million years – they are ultimately linked to slight shifts in solar radiation caused by predictable changes in Earth’s rotation and axis.

Roman Emperor Vespasian's Villa Found

An archaeologist works on the site of Roman Emperor Vespasian's summer villa. Titus Flavius Vespasianus, the emperor who ordered the construction of the Colosseum, ascended to the throne at the ripe old age of 60 and remained emperor until his death at age 69.

From Discovery News:

Aug. 6, 2009 -- The summer villa of Roman Emperor Vespasian has been found in the Sabine hill country northeast of Rome, Italian archaeologists announced today.

Titus Flavius Vespasianus is known for rebuilding the Roman Empire following the tumultuous reign of Emporer Nero. Vespasian changed the face of Rome by launching a major public works program, which included the construction of the Colosseum, the structure that arguably defines the glory of ancient Rome.
