From The Independent:

Repairs to two small helium leaks in the world's largest atom smasher will delay the restart of the giant machine another month until November, a spokesman for the operator said.

James Gillies said an additional setback to the timing could result if some other problem is found, but the European Organisation for Nuclear Research is taking pains to make sure it avoids another major shutdown like the electrical failure of Sept. 19.

Web Use Flattens As Behaviors Change

From CBS News/CNET:

The amount of time people spend online has not increased since last year, according to a report released by Forrester on Monday. Perhaps more interesting, however, is the reason for the trend: people's online behavior has changed.

"Engagement with the online channel has deepened," writes Forrester analyst Jackie Anderson. "Web users are becoming savvier and are better multi-taskers. Many know exactly where they want to go when they log in."

From Live Science:

Mammals, birds and fish are among evolution’s "winners," while crocodiles and other reptiles have ended up on the losing end, a new study suggests.

"Our results indicate that mammals are special," said study leader Michael Alfaro of UCLA.

The research allowed scientists to calculate for the first time which animal lineages have exceptional rates of success. The so-called "winners" have more species in their group, which means they have successfully evolved and diversified into many types of environments. The losers have diversified less, even over the course of millions of years.

From Time Magazine:

Boris Worm, a marine biologist at Dalhousie University in Canada, made a startling prediction in the pages of Science in 2006: if overfishing continued at then-current rates, he said, the world would essentially run out of seafood by 2048. Worm's bold analysis whipped up controversy in the usually pacific world of marine science — one colleague, Ray Hilborn of the University of Washington, called the Science study "mindbogglingly stupid." But Worm held fast to his predictions: that the oceans had limits, and that marine species were declining so fast that they would eventually disappear.

This Year's Mild Season In Tornado Alley Frustrates Scientists

From Yahoo News/AP:

DES MOINES, Iowa – This has been an unusually mild year in Tornado Alley, which is good news, of course, for the people who live here, but a little frustrating to scientists who planned to chase twisters as part of a $10 million research project.

"You're out there to do the experiment and you're geared up every day and ready. And when there isn't anything happening, that is frustrating," said Don Burgess, a scientist at the University of Oklahoma. But he was quick to add that he is pleased the relative quiet has meant fewer injuries and less damage.

Planet Solar courtesy Planet Solar, via CNN

From Popular Science:

In 2007, the first solar electric boat crossed the Atlantic Ocean. Now a Swiss group wants to cover that distance and keep going, circling the globe on nothing but the sun's power for the first time.

The team of engineers and scientists has embarked on the building of its 98-foot long vessel, dubbed Planet Solar, in Kiel, Germany. The boat's power will come from the 5,000 square feet of solar panels, about the size of two tennis courts, covering its broad deck. When the sun is shining bright above, they will convert 23 percent of the sun's rays to energy -- six percent more than average solar panels.

Comet Likely Culprit In Tunguska Blast

Tunguska Blast

From Science News:

Night-shining clouds created after space shuttle launches may offer clues into the cause of the Tunguska event, a mysterious blast which rocked southern Siberia more than a century ago.

Thin clouds have appeared at abnormally high altitudes over polar regions following space shuttle launches on several occasions in the past decade. These noctilucent, or night-shining, clouds typically occur in summer and lie at altitudes of about 85 kilometers, in a layer of the atmosphere called the thermosphere, says Michael C. Kelley, an atmospheric physicist at Cornell University. Kelley and his colleagues suggest in the July 28 Geophysical Research Letters that data gleaned from analyses of these high-flying clouds, as well as knowledge about the speed at which shuttle exhaust wafted to polar regions, now hint that the Tunguska blast of June 1908 (SN: 6/21/08, p. 5) resulted from a comet slamming into Earth’s atmosphere.

Laser Propulsion: Wild Idea May Finally Shine

From Space.com:

New laser propulsion experiments are throwing light on how to build future hypersonic aircraft and beam spacecraft into Earth orbit.

Indeed, a "Lightcraft revolution" could replace today's commercial jet travel. Passengers would be whisked from one side of the planet to the other in less than an hour - just enough time to get those impenetrable bags of peanuts open. Furthermore, beamed energy propulsion can make flight to orbit easy, instead of tenuous and dangerous.

That's the belief of Leik Myrabo an aerospace engineering professor at Rensselaer Polytechnic Institute in Troy, NY. He's an expert in directed energy applications, aerospace systems, space prime power, and advanced propulsion.

Collision Course: The Need for Better Space Junk Regulations

From Popular Mechanics:

With 3000 satellites and a growing arsenal of space junk, Earth’s orbit is a crowded area. If debris continues to accumulate, low Earth orbit could eventually become too congested for safe satellite use and space travel. Unfortunately, space junk is hard to regulate and even harder to clean up. Here’s an overview of existing space junk laws and some proposals for addressing the problems with debris in space.

Close calls in orbit happen all the time—scientists estimate that launch vehicles and other objects come within striking distance of one other over 1000 times a day. So when tracking reports on Feb. 10, 2009, predicted that Iridium 33, a 12-foot-long, 1200-pound communications satellite, and a 1-ton Russian military sat, Kosmos 2251, would pass within less than half a mile of each other, no one was alarmed. It wasn’t the closest call predicted for that day, or even the closest pass for any of the 66 Iridium satellites that coming week. But at the time of the predicted approach, Iridium 33 fell silent.

Fermi Paradox Points to Fewer Than 10 Extraterrestrial Civilizations

From Technology Review:

The absence of alien probes visiting the solar system places severe limits on the number of advanced civilizations that could be exploring the galaxy.

The Fermi paradox focuses on the existence of advanced civilizations elsewhere in the galaxy. If these civilizations are out there--and many analyses suggest the galaxy should be teeming with life--why haven't we seen evidence of them?

Today Carlos Cotta and Álvaro Morales from the University of Malaga in Spain add another angle to the discussion. One consideration is the speed at which a sufficiently advanced civilization could colonize the galaxy. Various analyses suggest that using spacecraft that travel at a tenth of the speed of light, a colonization wave could take some 50 million years to sweep the galaxy. Others have calculated that it may be closer to 13 billion years, which may explain why we have yet to spot extraterrestrials.

Skype Could Be Cut Off For Good Over Dispute

(Paul Rogers/The Times)

From Times Online:

Skype might have to shut down because of a dispute over the core technology used to make the internet telephone system work.

EBay, which paid $2.6 billion (£1.6 billion) for the voice-over-the-internet system in 2005, is facing a court battle with the original founders of the company who retained the rights to the technology at the heart of the system.

EBay admitted in a regulatory filing that it might have to close down the company. It said it was trying to develop alternative software but if that did not work, or if eBay lost the right to the original software: "Skype would be severely and adversely affected and the continued operation of Skype's business as currently conducted would likely not be possible."

Nap Time! One-Third Of Americans Do It

From Live Science:

A mid-day nap is more common than you might think in America.

One-third of U.S. adults nap on a typical day, according to a new survey from the Pew Research Center.

Naps are more common among men than women, and more common among the poor than the rich.

Naps can be good for you. A study last year in the journal Nature Neuroscience found a 90-minute daytime nap helped test subjects remember things better.

And naps are natural. Humans are bi-phasic sleepers, experts say, which means we're meant to sleep in bouts, not long stretches.

The new survey of 1,488 adults was released this week.

Why Does Coke From a Glass Bottle Taste Different?

The Usual Suspects: Various container materials might impart slight changes to Coke's flavor. Courtesy The Coca-Cola Company

From Popular Science:

It doesn’t. That’s what Coca-Cola’s spokespeople say, anyway. “The great taste of Coca-Cola is the same regardless of the package it comes in,” they insist. Rather, they say, “the particular way that people choose to enjoy their Coke can affect their perception of taste.” Sure, most people would agree that the cola is indeed delicious and refreshing, and pouring it into a glass or serving it over ice could influence the sensation of its flavor. But is it possible that the subtle variation in taste that some notice among aluminum cans, plastic bottles and glass bottles is more than just a psychological effect of their soda-consumption rituals?

Italian Archaeologists Find Lost Roman City Of Altinum Near Venice

From Times Online:

The bustling harbour of Altinum near Venice was one of the richest cities of the Roman empire. But terrified by the impending invasion of the fearsome Germanic Emperor Attila the Hun, its inhabitants cut their losses and fled in AD452, leaving behind a ghost town of theatres, temples and basilicas.

Altinum was never reoccupied and gradually sunk into the ground. The city lived on in Venetian folk tales and historical artefacts but its exact position, size and wealth gradually faded into obscurity.

Now, using aerial photography of the region, Italian archaeologists have not only located the city, but have produced a detailed map revealing its remarkably intact infrastructure and showing it to be slightly larger than Pompeii.

Panel Wants Deep Space, Not Landings as U.S. Goal

From The New York Times:

A panel examining the future of the United States’ human spaceflight program will suggest that the Obama administration may want to skip the part about landing on other worlds.

That could, panel members said Thursday, enable the National Aeronautics and Space Administration to send astronauts to more corners of the solar system more quickly while keeping within a limited budget. But it would also eliminate the possibility of astronauts leaving new iconic footprints on the Moon or Mars for a couple of decades.

At a public meeting in Cocoa Beach, Fla., the 10-member panel discussed at length the possibilities of where NASA might go next and how it might get there.

White Roofs Catch On as Energy Cost Cutters

A Wal-Mart store in Chino, Calif., has both a cool roof and solar panels to cut its energy use. J. Emilio Flores for The New York Times

From The New York Times:

SAN FRANCISCO — Returning to their ranch-style house in Sacramento after a long summer workday, Jon and Kim Waldrep were routinely met by a wall of heat.

“We’d come home in the summer, and the house would be 115 degrees, stifling,” said Mr. Waldrep, a regional manager for a national company.

He or his wife would race to the thermostat and turn on the air-conditioning as their four small children, just picked up from day care, awaited relief.

All that changed last month. “Now we come home on days when it’s over 100 degrees outside, and the house is at 80 degrees,” Mr. Waldrep said.

Their solution was a new roof: a shiny plasticized white covering that experts say is not only an energy saver but also a way to help cool the planet.

Relying on the centuries-old principle that white objects absorb less heat than dark ones, homeowners like the Waldreps are in the vanguard of a movement embracing “cool roofs” as one of the most affordable weapons against climate change.

ScienceDaily (July 30, 2009) — The human brain can adapt to changing demands even in adulthood, but MIT neuroscientists have now found evidence of it changing with unsuspected speed. Their findings suggest that the brain has a network of silent connections that underlie its plasticity.

The brain’s tendency to call upon these connections could help explain the curious phenomenon of “referred sensations,” in which a person with an amputated arm “feels” sensations in the missing limb when he or she is touched on the face. Scientists believe this happens because the part of the brain that normally receives input from the arm begins “referring” to signals coming from a nearby brain region that receives information from the face.

Can The Military Find The Answer To Alternative Energy?

From Business Week:

DARPA, the Defense Dept. agency that helped invent the Internet, is setting its sights on cleantech.

Nine years ago, Robert J. Nowak, an electro-chemicals expert for the Defense Dept., learned that senior generals weren't happy with their troops' electronic gear. While the night-vision, laser, and GPS devices worked well, the batteries that powered them weighed some 25 pounds per soldier, heavy enough to hurt some of the troops.

So Nowak, who worked at the Defense Advanced Research Projects Agency (DARPA), the Defense Dept.'s famous research branch, solicited bids for a new device that would power a soldier's gear at a tenth of the weight and a fraction of the $100 cost of the batteries. Today, the original 18 companies that took up Nowak's challenge have been whittled down to two: Livermore (Calif.)-based UltraCell and Adaptive Materials of Ann Arbor, Mich. Their solution: small, sturdy fuel cells that can power a soldier's clutch of mobile devices for a week on a gallon or so of methanol or propane. Battle-ready versions of the fuel cells will be available this year.

Any avid reader knows the power of a book to transport you into another world, be it the wizard realm of "Harry Potter" or the legal intrigue of the latest John Grisham.

Part of the reason we get lost in these imaginary worlds might be because our brains effectively simulate the events of the book in the same way they process events in the real world, a new study suggests.

The new study, detailed in the July 21 issue of the journal Psychological Science, builds on previous work that links the way our brains process images and written words to the way they process actions we perform ourselves.

Abu Dhabi Firm Takes Stake In Virgin Galactic, Plans Spaceport

SpaceShip Two and Mothership Virgin Galactic

From Popsci.com:

Space tourism is coming to the Middle East, as Abu Dhabi-based Aabar investments announced today it has taken a $280 million, 32 percent stake in Virgin Galactic. As part of the deal, which is still pending regulatory approval, Aabar plans to build a spaceport in Abu Dhabi, the capital of the United Arab Emirates, and will have rights to all Virgin Galactic traffic in that region. Aabar is also setting aside $100 million to build a small satellite launching facility, suggesting that the team plans to use the spaceport as a base for scientific research as well as space tourism.

Panel Backs NASA Bid For Bigger Shuttle Budget

From Yahoo News/Reuters:

CAPE CANAVERAL, Florida (Reuters) – The United States needs to boost NASA's budget by $1.5 billion to fly the last seven shuttle missions and should extend International Space Station operations through 2020, members of a presidential panel reviewing the U.S. human space program said on Tuesday.

A subcommittee of the 10-member board also proposed adding an extra, eighth shuttle flight to help keep the station supplied and narrow an expected five- to seven-year gap between the time the shuttle fleet is retired and a new U.S. spaceship is ready to fly.

A third option would keep the shuttle flying through 2014 as part of a plan to develop a new launch system based on existing shuttle rockets and components.

Longer Life For The Space Station Is Advised

From The New York Times:

Members of the government panel reviewing NASA’s human spaceflight program said Tuesday that the life of the International Space Station should be extended past its planned demise in 2016.

After the shuttle Endeavour, which undocked from the space station Tuesday afternoon, returns to Earth, NASA has seven flights left on its schedule before the shuttle fleet is to be retired in September 2010. At that point the space station, under construction since 1998, would finally be complete, but current plans call for operating it only through 2015 before it is deliberately disposed of in the ocean the following year.

Pictured: The Soap Bubble Nebula Causing Astronomical Excitement Among Star-Gazers

This startling image of the newly discovered Soap Bubble Nebula has generated enormous excitement among astronomers

From The Daily Mail:

It may look as if a child's soap bubble has strayed in front of a camera lens, but this extraordinary image from the heavens shows a newly discovered planetary nebula.

The phenomenon, which is caused when stars die and blast out a glowing shell of gas and plasma, was spotted by an amateur astronomer earlier this month.

Most planetary nebulae are elliptical or cigar-shaped, but in this case, its unusual shape was caused after a vast spherical cloud of gas was ejected from each pole of an ageing star.

China's Three Biggest Power Firms Emit More Carbon Than Britain, Says Report -- The Guardian

Greenpeace report names top three polluters and calls for tax on coal to improve efficiency and encourage switch to renewables

China's three biggest power firms produced more greenhouse gas emissions last year than the whole of Britain, according to a Greenpeace report published today.

The group warned that inefficient plants and the country's heavy reliance on coal are hindering efforts to tackle climate change. While China's emissions per capita remain far below those of developed countries, the country as a whole has surpassed the United States to become the world's largest emitter.
