Clinical Immortality And Space Settlement

From The Space Review:

There was a recent article in the New York Times, “Three Score and Ten”, which was inspired by a Lancet paper that predicted the median life expectancy for babies born in America in 2007 is greater than or equal to 104. In 3000 BC, it was 24 and stayed there almost until the industrial revolution. In 1850, it was 38. In 1909, it was 50. In 1959, it was 67. Current demographics indicate it’s only 78. The extra 26 years that Lancet predicts comes from anticipated future improvements in reducing death rates (morbidity).

From Science Daily:

ScienceDaily (Oct. 30, 2009) — As the nation copes with a shortage of vaccines for H1N1 influenza, a team of Alabama researchers have raised hopes that they have found an Achilles' heel for all strains of the flu -- antioxidants.

In an article appearing in the November 2009 print issue of the FASEB Journal, they show that antioxidants -- the same substances found in plant-based foods -- might hold the key in preventing the flu virus from wreaking havoc on our lungs.

Rest Easy: Retirement (and Money) Can Improve Sleep

Insomnia is the most common sleep complaint at any age. It affects almost half of adults 60 and older, according to the National Institutes of Health. Credit: © Marcin Kempski |Dreamstime.com"

From Live Science:

It's no secret the stress of work can keep you up at nights. Now research shows that retirement can spur less fitful sleep, at least for people who are financially stable.

The prevalence of sleep disturbances among 14,714 study participants in France — all of whom had pensions that continued to pay 80 percent of their salaries — fell from 24.2 percent in the last year before retirement to 17.8 percent in the first year after retiring.

The finding may not apply to retirees who lack financial stability, however.

From The Guardian:

One year after £30m meltdown, 'God Machine' is ready to run again in Switzerland.

At first glance, the piece of metal in Steve Myers's hands could be taken for a harmonica or a pen. Only on closer inspection can you make out its true nature. Myers, director of accelerators at the Cern particle physics laboratory outside Geneva, is clutching a section of copper piping from which a flat electrical cable is protruding.

Pictured: The Fridge-Sized Computer That Sent The Very First Email 40 Years Ago

The computer from which 40 years ago the first message was sent on the internet, between the University of California Los Angeles (UCLA) and Stanford University

From The Daily Mail:

The very first message to be sent between two computers - a breakthrough that helped usher in the internet and Mail Online - was sent exactly 40 years ago.

And to mark the occasion, celebrities, computer experts and entrepreneurs joined the man behind that first message for a bit of a party.

UCLA professor Leonard Kleinrock said: 'It's the 40th year since the infant internet first spoke.'

Russia Becomes The World's Taxicab To Space

From Christian Science Monitor:

Though its program is nothing like it once was, the country uses its fleet of rockets to ferry tourists and satellites into orbit.


Moscow - For better or mirth, it has become one of those indelible images from space: Canadian circus billionaire Guy Laliberté floating around the International Space Station wearing a red clown nose.

The stunt earlier this month by the founder of Cirque du Soleil, who once performed as a fire breather, was intended to provide a moment of levity for his wife and children during a video linkup. But it also served a more serious purpose: to draw attention to the crusade for which he paid $35 million to journey into orbit – the need for clean water on Earth.

From Discovery News:

Culture, not just genes, can drive evolutionary outcomes, according to a study released Wednesday that compares individualist and group-oriented societies across the globe.

Bridging a rarely-crossed border between natural and social sciences, the study looks at the interplay across 29 countries of two sets of data, one genetic and the other cultural.

Creative Is Latest To Tackle E-book Readers

From CNET:

The question is, who isn't getting in on the e-book reader action these days? Less than two weeks after we met Barnes & Nobles' Nook and just a few days after hearing of tire maker Bridgestone's plans for a flexible e-reader, our friends at Crave UK alerted us that Creative may be hopping on the e-reader bandwagon as well.

Creative fan site EpiZenter.net (so named for Creative's family of popular Zen MP3 players) reports that the company showed off a working model of its first e-book reader, tentatively named the MediaBook, at its annual general meeting Thursday in Singapore. The device reportedly has a touch screen, text-to-speech function, and an SD memory card slot. It will run on Creative's Zii System-On-Chip technology and will be Internet-enabled.

English Wine Gets Help From Space

The system can help to optimise harvests, and hopefully wine quality

From BBC:

A number of English vineyards have signed up to make use of a satellite imaging service to boost harvests.

The satellite measures a vineyard's reflectivity in a number of colours in the visible and infrared.

The Oenoview system, first launched in France last year, analyses the images to determine vine leaf density, soil water content and grape bunch sizes.

The English Wine Producers trade group said that wines made using the system could be available as early as 2011.

Heaven Can Wait

Patients recount near-death experiences in drawings

From Newsweek:

A new book promises incontrovertible proof of the afterlife. That's cold comfort to those of us left behind.

On a spring day last year, three months after the death of my younger son, Max, I opened my front door and saw a butterfly resting on the steps—an Eastern tiger swallowtail, I later determined, a species native to the Northeast but not one I remembered seeing before in the middle of Brooklyn. The date stuck in my mind because, as it happens, it was also my birthday. The butterfly, with its otherworldly beauty and silence, is, of course, a common metaphor for the soul. Its emergence from entombment as a chrysalis may have inspired ideas about human resurrection.

From Live Science:

Silken spider webs dating back some 140 million years have been discovered preserved in amber, scientists announce today.

The viscous tree sap flowed over the spider webs before hardening and preserving the contents, which were discovered in Sussex, England. Other bits sealed up in the amber included plant matter, insect droppings and ancient microbes.

CAMBRIDGE, Mass.--A group of academics on Friday considered the ultimate engineering challenge: building machines to stabilize the earth's climate.

The Massachusetts Institute of Technology convened a symposium here to discuss the potential benefits and pitfalls of geoengineering, also called climate engineering. Everything from shooting light-blocking particles into the atmosphere to "artificial trees" is being seriously studied, despite trepidation among researchers and opposition from others.

Fructose Causes High Blood Pressure?



From Future Pundit:

Beware a diet high in fructose.

A diet high in fructose increases the risk of developing high blood pressure (hypertension), according to a paper being presented at the American Society of Nephrology’s 42nd Annual Meeting and Scientific Exposition in San Diego, California. The findings suggest that cutting back on processed foods and beverages that contain high fructose corn syrup (HFCS) may help prevent hypertension.

A Molecule of Motivation, Dopamine Excels at Its Task

Serge Bloch

From The New York Times:

If you’ve ever had a problem with rodents and woken up to find that mice had chewed their way through the Cheerios, the Famous Amos, three packages of Ramen noodles, and even that carton of baker’s yeast you had bought in a fit of “Ladies of the Canyon” wistfulness, you will appreciate just how freakish is the strain of laboratory mouse that lacks all motivation to eat.

Rocket Men

From Newsweek:

Politicians won't get us back into the space race, but novelists just might.

Six months ago, President Obama asked a team of academics, astronauts, and aerospace executives to give him options for the future of the space program. Those options, as described in the Augustine Committee's just-released final report, must have sent a little thrill up our Spock-loving nerd in chief's leg: setting up a lunar base, flying to a Martian moon, etc. There's just one catch: NASA doesn't have the resources it needs to pursue these plans. Exciting proposals for voyages to alien moons aside, the report's attention to dollars and cents makes it a cosmic buzzkill.
