From Live Science:

The breaking of the sound barrier is not just an audible phenomenon. As a new picture from the U.S. military shows, Mach 1 can be quite visual.

This widely circulated new photo shows a Air Force F-22 Raptor aircraft participating in an exercise in the Gulf of Alaska June 22, 2009 as it executes a supersonic flyby over the flight deck of the aircraft carrier USS John C. Stennis.

The visual phenomenon, which sometimes but not always accompanies the breaking of the sound barrier, has also been seen with nuclear blasts and just after space shuttles launches, too. A vapor cone was photographed as the Apollo 11 moon-landing mission rocketed skyward in 1969.

From The New York Times:

ATHENS — Not long before the new Acropolis Museum opened last weekend, the writer Christopher Hitchens hailed in this newspaper what he called the death of an argument.

Britain used to say that Athens had no adequate place to put the Elgin Marbles, the more than half of the Parthenon frieze, metopes and pediments that Lord Elgin spirited off when he was ambassador to the Ottoman Empire two centuries ago. Since 1816 they have been prizes of the British Museum. Meanwhile, Greeks had to make do with the leftovers, housed in a ramshackle museum built in 1874.

So the new museum that Bernard Tschumi, the Swiss-born architect, has devised near the base of the Acropolis is a $200 million, 226,000-square-foot, state-of-the-art rebuttal to Britain’s argument.

Is Farming The Root Of All Evil

Cereal killer: the introduction of agriculture was followed by malnutrition and disease Photo: GETTY

From The Telegraph:

Academics have claimed that moving away from a hunter-gatherer lifestyle was 'the worst mistake in history'. But are they right?

Last week, Sir Paul McCartney urged us, amid a blaze of publicity, to curb our carnivorous lifestyles and go meat-free on Mondays, in order to reduce the damage that modern agriculture does to the planet. But for all the recent talk about the pros and cons of farming, and how the methods we use are affecting the environment, a more basic point has been missed e_SEnD that growing crops might be damaging not just to the environment but to the development of our own species. Could it be that rather than being a boon to mankind, the invention of agriculture was, in the words of one academic, "the worst mistake in human history"?

Scots Fought 'In Bright Yellow War Shirts Not Braveheart Kilts'

From The Telegraph:

Medieval Scottish soldiers fought wearing bright yellow war shirts dyed in horse urine rather than the tartan plaid depicted in the film Braveheart, according to new research.

Historian Fergus Cannan states that the Scots armies who fought in battles like Bannockburn, and Flodden Field would have looked very different to the way they have traditionally been depicted.

Instead of kilts, he said they wore saffron-coloured tunics called "leine croich" and used a range of ingredients to get the boldest possible colours.

Sen. Inhofe Calls for Inquiry Into 'Suppressed' Climate Change Report -- FOX News

Republicans are raising questions about why the EPA apparently dismissed an analyst's report questioning the science behind global warming.

A top Republican senator has ordered an investigation into the Environmental Protection Agency's alleged suppression of a report that questioned the science behind global warming.

The 98-page report, co-authored by EPA analyst Alan Carlin, pushed back on the prospect of regulating gases like carbon dioxide as a way to reduce global warming. Carlin's report argued that the information the EPA was using was out of date, and that even as atmospheric carbon dioxide levels have increased, global temperatures have declined.

Getting Old Is Better Than Expected

From Live Science:

When do we get old? People age 18 to 29 say "old age" starts at about 60. But those in middle-age figure it starts at 70. And those 65 and older put the threshold at 74.

So it goes with other perceptions about aging in a new survey form the Pew Research Center. The disparities between what younger people expect will happen as they age, and what really happens, are stark.

Good memory, good health, good sex. It's enough to make the grandkids cringe!

Adults age 18 to 64 were asked what they expect will happen when they get old. Those 65 and older were asked what actually has happened to them. The results (18-64 / 65 and older):

Oldest Known Portrait Of St Paul Revealed By Vatican Archaeologists

The 4th-century portrait was found in the catacombs of St Thecla,
not far from the Basilica of St Paul's Outside the Walls.

From Times Online:

Vatican archaeologists have uncovered what they say is the oldest known portrait of St Paul. The portrait, which was found two weeks ago but has been made public only after restoration, shows St Paul with a high domed forehead, deep-set eyes and a long pointed beard, confirming the image familiar from later depictions.

L'Osservatore Romano, the Vatican newspaper, which devoted two pages to the discovery, said that the oval portrait, dated to the 4th century, had been found in the catacombs of St Thecla, not far from the Basilica of St Paul’s Outside the Walls, where the apostle is buried. The find was “an extraordinary event”, said Monsignor Gianfranco Ravasi, head of the Pontifical Council for Culture.

Swine Flu 'Shows Drug Resistance'

From The BBC:

Experts have reported the first case of swine flu that is resistant to tamiflu - the main drug being used to fight the pandemic.

Roche Holding AG confirmed a patient with H1N1 influenza in Denmark showed resistance to the antiviral drug.

David Reddy, company executive, said it was not unexpected given that common seasonal flu could do the same.

The news comes as a nine-year-old girl has become the third to die in the UK with swine flu.

It is understood from her doctors at Birmingham Children's Hospital that she had underlying health conditions. It is not yet known whether swine flu contributed to her death.

Men Agree On What's Hot In The Opposite Sex (But Girls Do Not)

Image: Queen of the seductive pose: Katie Price ticks the boxes for men as she is thin and confident

From The Daily Mail:

Men agree on what is attractive in the opposite sex far more than women do, says a study.

The survey of 4,000 adults found that most men liked women who were thin and posing seductively.

Women, in contrast, were enticed by a far wider range of male characteristics.

The results could explain why women feel pressured to conform to a narrow view of attractiveness, and suffer more eating disorders, the scientists said.

Participants in the study rated photographs of men and women aged 18 to 25 for attractiveness.

Great Wall of Facebook: The Social Network's Plan to Dominate the Internet — and Keep Google Out

From Wired News:

Larry Page should have been in a good mood. It was the fall of 2007, and Google's cofounder was in the middle of a five-day tour of his company's European operations in Zurich, London, Oxford, and Dublin. The trip had been fun, a chance to get a ground-floor look at Google's ever-expanding empire. But this week had been particularly exciting, for reasons that had nothing to do with Europe; Google was planning a major investment in Facebook, the hottest new company in Silicon Valley.

Innovation: Physics Brings Realism To Virtual Reality

From New Scientist:

Innovation is our regular column that highlights the latest emerging technological ideas and where they may lead.

Computer games have come a long way from the pixelated graphics of the 1980s to the more polished characters of today. But the inexorable creep of Moore's Law has now taken us to the brink of further giant changes.

The latest multi-core processors and some smart software allow techniques used by physicists and engineers to simulate the real world in extreme detail to be used to create virtual worlds governed by real physics, rather than the simplified versions used today.

Debate: Can The Internet Handle Big Breaking News?

From CNET News:

It happens time and time again: when news breaks, the Internet slows.

It's quite obvious at this point that the Internet has muscled its way into the lives of anyone who needs information. And Michael Jackson's death Thursday had as great an impact on the Internet as anything in the history of the medium that didn't involve the World Trade Center.

The statistics are amazing: Akamai said worldwide Internet traffic was 11 percent higher than normal during the peak hours between 3 p.m. PDT and 4 p.m., when news of Jackson's death was breaking. That traffic forced even Google to its knees for a brief period of time Thursday afternoon.

Archaeological Treasure Trove Surfaces In S.C.

From The State:

HILTON HEAD — An archaeologist who’s been digging at the Topper Site in Allendale County for 11 years is uncovering new evidence that could rewrite America’s history.

University of South Carolina archaeologist Albert Goodyear found artifacts at this rock quarry site near the Savannah River that indicate humans lived here 37,000 years before the Clovis people. History books say the Clovis were the first Americans and arrived here 13,000 years ago by walking across a land bridge from Asia.

Goodyear’s discovery could prove otherwise.

His findings are controversial, opening scientific minds to the possibility of an even earlier pre-Clovis occupation of America.

From Science Daily:

ScienceDaily (June 28, 2009) — Experiment after experiment confirms that a diet on the brink of starvation expands lifespan in mice and many other species. But the molecular mechanism that links nutrition and survival is still poorly understood. Now, researchers at the Salk Institute for Biological Studies have identified a pivotal role for two enzymes that work together to determine the health benefits of diet restriction.

When lacking one enzyme or the other, roundworms kept on a severely calorie-restricted diet no longer live past their normal lifespan, they report in the June 24, 2009, advance online edition of the journal Nature.
