International Space Station To Get A Big, Beautiful Window

International Space Station Cupola Window: NASA

From Popsci.com:

We've seen private tourists and urine-recycling water filters make their way onto the International Space Station, but breathtaking views have never been the station's strongest selling point. Because of external hazards such as solar radiation and orbiting space debris, the biggest window is only 20 inches. Until now, that is.

The Tranquility node of the ISS is slated for a new 31-inch window, dubbed the Cupola, that will provide views of space never before seen from inside the station. NASA says astronauts will be able to gaze at Earth and the stars. [NASA via Boing Boing]

Huge Underground Chamber Found--Early Christian Refuge?

A human-made, underground cave (pictured)—the largest in Israel—likely began life 2,000 years ago as a quarry but may have gone on to become a monastery, a refuge for persecuted Christians, or a Roman army base, experts said in June 2009. Photograph courtesy Moshe Einav, University of Haifa

From National Geographic:

A 2,000-year-old underground chamber has been discovered in Israel's Jordan Valley.

The largest human-made cave in Israel, the 1-acre (0.4-hectare) space is thought to have begun as a quarry. In subsequent centuries it may have served as a monastery, hideout for persecuted Christians, or Roman army base, experts say.

Archaeologists working in the valley found the cave this past March when they came across a hole in a rock face.

As they were about to enter, two fearful-looking Bedouins appeared and warned the team that hyenas and wolves inhabited the cave.

From Technology Review:

Researchers at a California National Lab will soon attempt to start self-sustaining fusion reactions using the world's largest lasers. If it works, it could be a first step on the road to abundant fusion power.

It's late April and workers are assembling the last parts of the National Ignition Facility (NIF), a sprawling building covering the area of three football fields at Lawrence Livermore National Laboratory in Livermore, CA. Dressed in hard hats, hair nets, lab coats, and latex gloves, they have gathered at the target chamber, a sphere 10 meters in diameter and bristling with 48 burnished-aluminum ducts that together house 192 separate laser beams. Each beam on its own is one of the world's most powerful, says Bruno Van Wonterghem, operations manager at NIF. Together they deliver 50 to 60 times the energy of any other laser.

From Science Daily:

ScienceDaily (July 1, 2009) — Scientists from Texas are batty over a new discovery which could lead to the single most important medical breakthrough in human history—significantly longer lifespans. The discovery, featured on the cover of the July 2009 print issue of The FASEB Journal, shows that proper protein folding over time in long-lived bats explains why they live significantly longer than other mammals of comparable size, such as mice.

"Ultimately we are trying to discover what underlying mechanisms allow for some animal species to live a very long time with the hope that we might be able to develop therapies that allow people to age more slowly," said Asish Chaudhuri, Professor of Biochemistry, VA Medical Center, San Antonio, Texas and the senior researcher involved in the work.

From Live Science:

When poured, sand behaves much like water to form water-like droplets, scientists have discovered.

The finding could be important to a wide range of industries that use "fluidized" dry particles for oil refining, plastics manufacturing and the drug industry, the researchers say.

Researchers previously thought dry particles lacked sufficient surface tension to form droplets like ordinary liquids. But physicists from the Materials Research Science and Engineering Center at the University of Chicago, led by professor Heinrich M. Jaeger, used high-speed photography to measure minute levels of surface tension and detect droplet formation in flows of dry granular materials.

SETI And The Singularity

From The Futurist:

The Search for Extra-Terrestrial Intelligence (SETI) seeks to answer one of the most basic questions of human identity - whether we are alone in the universe, or merely one civilization among many. It is perhaps the biggest question that any human can ponder.

The Drake Equation, created by astronomer Frank Drake in 1960, calculates the number of advanced extra-terrestrial civilizations in the Milky Way galaxy in existence at this time. Watch this 8-minute clip of Carl Sagan in 1980 walking the audience through the parameters of the Drake Equation. The Drake equation manages to educate people on the deductive steps needed to understand the basic probability of finding another civilization in the galaxy, but as the final result varies so greatly based on even slight adjustments to the parameters, it is hard to make a strong argument for or against the existence of extra-terrestrial intelligence via the Drake equation. The most speculative parameter is the last one, fL, which is an estimation of the total lifespan of an advanced civilization. Again, this video clip is from 1980, and thus only 42 years after the advent of radio astronomy in 1938.

Sprawl! Is Earth Becoming A Planet of SuperCities?

From The Daily Galaxy:

Imagine a planet dominated by cities like Mega-City One, a megalopolis of over 400 million people across the east coast of the United States, featured in the Judge Dredd comic or "San Angeles," formed from the joining of Los Angeles, Santa Barbara, San Diego, and the surrounding metropolitan regions following a massive earthquake featured in the 1993 movie "Demolition Man."

Don't hold your breath: the 21st century will soon have 19 cities with populations of 20 million or more.

The history of the human species is a history of migration. In 1000 A.D. Cordova, Spain was the largest city. By 1500, Bejing began its rise to power, and 300 years later it was the first city to be over a million people. By 1900 London emerged the world's supercity with over 6 million people. In 1950 New York was proclaimed the first "megacity" with a population of over 10 million people in the greater metropolitan area.

Elgin Marble Argument In A New Light

The bronzed original sculptures stand in contrast to the white reproductions of the part of the frieze now displayed in the British Museum. Thanassis Stavrakis/Associated Press

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"?

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.

Black Holes On A Desktop

From The Economist:

Sound may offer a better way than light to test Stephen Hawking’s prediction that black holes emit radiation.

WHEN the Large Hadron Collider, a giant particle accelerator near Geneva, was switched on last September, the press was full of scare stories about the risk of it producing a tiny black hole that would, despite its minuscule size, quickly swallow the Earth. In fact, the first test runs could never have made such an object. And, just over a week later, the LHC broke and has not yet been repaired. But it is true that one of the things its operators would like to create, if and when they get it going again, are miniature versions of those fabled astronomical objects whose intense gravity means no light can escape them.

One In 25 Deaths Worldwide Attributable To Alcohol

From Science Daily:

ScienceDaily (June 27, 2009) — Research from Canada's own Centre for Addiction and Mental Health (CAMH) featured in this week's edition of the Lancet shows that worldwide, 1 in 25 deaths are directly attributable to alcohol consumption. This rise since 2000 is mainly due to increases in the number of women drinking.

CAMH's Dr Jürgen Rehm and his colleagues found that alcohol-attributable disorders are among the most disabling disease categories within the global burden of disease, especially for men. And in contrast to other traditional risk factors for disease, the burden attributable to alcohol lies more with younger people than with the older population.

Study Dispels Myth of Post-Workout Fat Burn

Yes, you burn calories while weightlifting, running or doing other exercise. No, the calorie burn does not continue as you pig out later. Image credit: stockxpert

From Live Science:

After an intense hour of sweating on the treadmill or pumping iron, most of us look forward to the extra post-exercise "afterburn" of fat cells that has been promised to us by fitness pundits. This 24-hour period of altered metabolism is supposed to help with our overall weight loss.

Unfortunately, a recent study found this to be a myth for moderate exercisers.

The new research clarifies a misunderstanding that exercisers can ignore their diet after a workout because their metabolism is in this super active state.

"It's not that exercise doesn't burn fat," said Edward Melanson, associate professor of medicine at the University of Colorado, "It's just that we replace the calories. People think they have a license to eat whatever they want, and our research shows that is definitely not the case. You can easily undo what you set out to do.”

The findings were detailed in the April edition of Exercise and Sport Sciences Review.

Vatican’s Celestial Eye, Seeking Not Angels But Data

From The New York Times:

MOUNT GRAHAM, Ariz. — Fauré’s “Requiem” is playing in the background, followed by the Kronos Quartet. Every so often the music is interrupted by an electromechanical arpeggio — like a jazz riff on a clarinet — as the motors guiding the telescope spin up and down. A night of galaxy gazing is about to begin at the Vatican’s observatory on Mount Graham.

“Got it. O.K., it’s happy,” says Christopher J. Corbally, the Jesuit priest who is vice director of the Vatican Observatory Research Group, as he sits in the control room making adjustments. The idea is not to watch for omens or angels but to do workmanlike astronomy that fights the perception that science and Catholicism necessarily conflict.

Brains Replay Memories While We Sleep And Store The Highlights, Claim Scientists

From The Telegraph:

We may think we are asleep - but deep in the recesses of our mind a "memory editor" is working overtime, replaying the experiences of the day and storing the highlights on our brain's version of a video recorder, claim scientists.

Researchers have discovered that the mind keeps most memories for just a day but then at night acts like a film editor sifting through the "video clips" before transferring the best bits to long term storage in our own movie archive.

The research has "profound implications" for the importance of sleep and its link with long term memory, they said.

Sun Leaves Earth Wide Open To cCsmic Rays

From New Scientist:

THE sun provides ideal conditions for life to thrive, right? In fact, it periodically leaves Earth open to assaults from interstellar nasties in a way that most stars do not.

The sun protects us from cosmic rays and dust from beyond the solar system by enveloping us in the heliosphere - a bubble of solar wind that extends past Pluto. These cosmic rays would damage the ozone layer, and interstellar dust could dim sunlight and trigger an ice age. However, when the solar system passes through very dense gas and dust clouds, the heliosphere can shrink until its edge is inside Earth's orbit.

Light Goes Out On Solar Mission

From The BBC:

After more than 18 years studying the Sun, the plug is finally being pulled on the ailing spacecraft Ulysses.

Final communication with the joint European-US satellite will take place on 30 June.

The long-serving craft, launched in October 1990, has already served four times its expected design life.

The Esa-Nasa mission was the first to survey the environment in space above and below the poles of the Sun.

Data from the craft, published last year, also suggested that the solar wind - the stream of charged particles billowing away from the Sun - is at its weakest for 50 years.

From Science Daily:

ScienceDaily (June 25, 2009) — For climatologists, part of the challenge in predicting the future is figuring out exactly what happened during previous periods of global climate change.

One long-standing climate puzzle relates to a sequence of events 33.5 million years ago in the Late Eocene and Early Oligocene. Profound changes were underway. Globally, carbon dioxide levels were falling and the hothouse warmth of the dinosaur age and Eocene Period was waning. In Antarctica, ice sheets had formed and covered much of the southern polar continent.

Dreaming Of Nonsense: The Evolutionary Enigma Of Dream Content

From Scientific American:

Friday, June 19, 2:12 a.m.: Loading up the trunk of my car with clothes hangers when approached by two transients… try to engage them in good-natured conversation about the benefits of wooden clothes hangers over metal ones, but they make me uneasy, say they want to go out to get a drink but I’ve got to go. In a city somewhere… looks like a post-apocalyptic Saint Louis.

Saturday, June 20, 4:47 a.m.: Was just now trying to return my dead grandmother’s cane to her. Took elevator to her apartment… meant to go to the 8th floor, but elevator lurched up to the 18th floor, swung around violently then shot back down. Could hear voices in the corridors outside elevator shaft…. a mother yelling at her child. Grandma then became my other grandma, also decesased, yet in a nursing home; doctors say she’s doing fine.
