Space 'Causes Disabling Headaches In Astronauts'

Astronaut: Twelve of the 17 astronauts reported 21 headaches during the test Photo: AP

From The Telegraph:

Astronauts who have no history of bad headaches can be prone to disabling attacks while in space, neurologists say.

Contrary to prevailing theories, headaches in space are not caused by motion sickness, they said.

Instead, the problem could lie in an increase in blood flow to the head, causing painful pressure on the brain.

How To Unleash Your Brain's Inner Genius

From New Scientist:

CLAD in a dark suit and sunglasses, Derek Paravicini makes a beeline for the sound of my voice and links his arm into mine. "Hello, Celeste. Where have you come from today?" I reply and his response is immediate: "From Holborn?" He repeats the word several times, savouring each syllable. "Hol-born, Hol-born, Hooool-bbooorn. Where's Hoollll-booorn?" As our conversation continues, the substance of much of what I say doesn't seem to sink in, but the sounds themselves certainly do, with Paravicini lingering over and repeating particularly delightful syllables. "Meewww-zick. The pi-aan-o."

Such touching and immediate friendliness is not quite what I expected from my first meeting with the 29-year-old, blind musical savant, but his obsession with reproducing sounds certainly makes sense, given his talent. Paravicini can play just about any piece of music you request, entirely from memory, with formidable technical ability, despite having severe learning difficulties that mean he needs constant support in everyday life. And as I find out an hour later, he constantly improvises the pieces he has learned by ear, rather than simply copying as you might expect.

Air France Flight 447: A Detailed Meteorological Analysis

From Watts Up With That?

NOTE: This writeup is from an acquaintance of mine who wrote some powerful meteorological software, Digital Atmosphere, that I use in my office. He used that software (and others) to analyze the Air France 447 crash from the meteorological perspective. h/t to Mike Moran – Anthony

by Tim Vasquez

Air France flight 447 (AF447), an Airbus A330 widebody jet, was reported missing in the equatorial Atlantic Ocean in the early morning hours of June 1, 2009. The plane was enroute from Rio de Janeiro (SBGL) to Paris (LFPG). Speculation suggested that the plane may have flown into a thunderstorm. The objective of this study was to isolate the aircraft’s location against high-resolution satellite images from GOES-10 to identify any association with thunderstorm activity. Breakup of a plane at higher altitudes in a thunderstorm is not unprecedented; Northwest Flight 705 in 1963 and more recently Pulkovo Aviation Flight 612 in 2006 are clear examples.

Who Controls The Internet?

From The Weekly Standard:

The United States, for now, and a good thing, too.

In order to please our European allies and our Third World critics, the Obama administration may be tempted to surrender one particular manifestation of American "dominance": central management of key aspects of the Internet by the U.S. Department of Commerce. Other countries are pushing for more control. Early this year, British cabinet member Andy Burnham told the Daily Telegraph that he was "planning to negotiate with Barack Obama's incoming American administration to draw up new international rules for English language websites." It would be a mistake for the administration to go along. America's special role in managing the Internet is good for America and good for the world.

From Science Daily:

ScienceDaily (June 3, 2009) — Electronic memory chips may soon gain the ability to bend and twist as a result of work by engineers at the National Institute of Standards and Technology (NIST). As reported in the July 2009 issue of IEEE Electron Device Letters, the engineers have found a way to build a flexible memory component out of inexpensive, readily available materials.

Though not yet ready for the marketplace, the new device is promising not only because of its potential applications in medicine and other fields, but because it also appears to possess the characteristics of a memristor, a fundamentally new component for electronic circuits that industry scientists developed in 2008. NIST has filed for a patent on the flexible memory device (application #12/341.059).

Single Women Look Longer at Men

From Live Science:

Single women look longer when they're checking out men than women who are taken, a new study finds.

Neuroscientist Heather Rupp, of The Kinsey Institute at Indiana University, had men and women rate 510 photos of faces of members of the opposite sex and give their gut reaction on the person's attractiveness, masculinity/femininity, and other subjective ratings.

The study included 59 men and 56 women ages 17 to 26, who were all heterosexual, from a variety of ethnic backgrounds and who were not using hormonal contraception. Some of the participants had sexual partners, while others did not (21 women did and 25 men did).

From ABC News Science (Australia):

Solar thermal power has the potential to generate up to a quarter of the world's electricity by 2050, according to a new report by pro-solar groups.

The study, by Greenpeace, the European Solar Thermal Electricity Association (ESTELA) and the International Energy Agency's (IEA) SolarPACES group, says huge investments would also create jobs and fight climate change.

"Solar power plants are the next big thing in renewable energy," says Sven Teske of Greenpeace International and co-author of the report.

Confirmed: Windows 7 Launches October 22

From PC World:

It's official: Windows 7 will make its debut on October 22. Microsoft confirmed the late-October launch date with PC World, details of which leaked out earlier today.

Windows 7 development should finish up in July, at which time it will be released to PC manufacturers. The October 22 date will be a full retail rollout for the OS - although pricing has yet to be announced.

Microsoft will provide a "tech guarantee" for upgrading users, though its details are still to come.

There were some rumblings of an October launch in late April. Microsoft's initial target release date was in January 2010, but the company did confirm last month that Windows 7 would make its debut this year, before the holiday shopping season.

What Makes Us Happy?

From The Atlantic:

Is there a formula—some mix of love, work, and psychological adaptation—for a good life? For 72 years, researchers at Harvard have been examining this question, following 268 men who entered college in the late 1930s through war, career, marriage and divorce, parenthood and grandparenthood, and old age. Here, for the first time, a journalist gains access to the archive of one of the most comprehensive longitudinal studies in history. Its contents, as much literature as science, offer profound insight into the human condition—and into the brilliant, complex mind of the study’s longtime director, George Vaillant.

Is Vaccine Refusal Worth The Risk?

From NPR:

Morning Edition, May 26, 2009 · Over the past 10 years, a highly contagious and sometimes fatal bacterial disease once thought to have been eradicated from the U.S. has re-emerged, threatening the youngest and weakest. Pertussis is a bacterial infection of the lungs and spreads from person to person through moisture droplets in the air, probably from coughs or sneezes. A person with pertussis develops a severe cough that usually lasts four to six weeks or longer.

Health officials cite an increase in the incidence of pertussis, particularly among infants and teenagers. In 1976, there were just over 1,000 reported cases of pertussis in the United States; by 2004, it had climbed to nearly 26,000 cases; and between 2000 and 2005, there were 140 deaths resulting from pertussis in the U.S.

Half of All Friends Replaced Every 7 Years

From Live Science:

You may have more Facebook friends as the years go by, but when it comes to your close friends, you lose about half and replace them with new ones after about seven years, new social research suggests.

As a result, the size of your social network stays about the same.

People might like to think they have control over whom they choose as friends, but social networks could also be influenced by the context in which we meet one another. Sociologist Gerald Mollenhorst of Utrecht University in the Netherlands was interested in finding out exactly how much our networks are shaped by social context or by personal preference.

It's a bwa-ha-ha kind of evil mastermind laugh—appropriate if you've just sacked Constantinople, checkmated Deep Blue, or handed Superman a Dixie cup of kryptonite Kool-Aid, but downright scary in a midtown Manhattan restaurant during the early-bird special.

Our fellow diners begin to stare. Tobias doesn't notice and wouldn't care anyway. He's as rumpled and wild as a nerdy grizzly bear. His place mat is covered in diagrams and sketched floor plans and scribbled arrows. His laugh fits him like a tinfoil hat. It goes on for a solid 20 seconds.

From Reuters:

GENEVA (Reuters) - The spread of H1N1 flu in Australia, Britain, Chile, Japan and Spain has nudged the world closer to a pandemic, the World Health Organisation said on Tuesday.

The newly-discovered strain had caused more infections than seasonal influenza at the start of Chile's flu season, raising concern about how it would spread in the southern hemisphere, according to Keiji Fukuda, the WHO's acting assistant director-general.

The virus has mainly affected people aged below 60 and caused 117 deaths worldwide, including some otherwise healthy people, he said. For now, the WHO's pandemic scale remained at the second-highest level but the threshold may soon be crossed.

"Globally we believe that we are at Phase 5 but we are getting closer to Phase 6," Fukuda told journalists. "The future impact of this infection has yet to unfold."

Air France Mystery: Was Lightning to Blame?

{Photograph by Jacques Demarthon/AFP/Getty Images)

From Popular Mechanics:

An Air France Airbus A330, carrying 228 people from Rio de Janeiro, Brazil, to Paris, entered an area of strong turbulence and disappeared. The CEO of AirFrance confirms that the airplane most likely crashed into the Atlantic Ocean. Some, including company officials, have speculated that the plane was struck down by lightning, a claim that is not at all outrageous. According to experts, most commercial aircraft are struck by lightning at some point in their lives. But can lightning down a plane? We spoke to the experts about the likelihood of lightning being the culprit in this tragic downing.

Aviation experts agree that it is highly unlikely that lightning alone caused the crash of Air France Flight 447 earlier today. The 2005 Airbus A330-200 twinjet with 228 aboard disappeared on a flight from Rio to Paris shortly after the aircraft sent out automated signals indicated it had suffered a catastrophic electrical failure and a sudden loss of cabin pressure while flying through an area of severe thunderstorms. Late this afternoon the Brazilian Air Force was reporting that the aircraft likely crashed in an area approximately 60 miles south of the Cape Verde Islands off the coast of Senegal. Air France spokesman Francois Brousse this morning stoked mounting speculation when he said "it is possible" the plane was hit by lightning.

From Yahoo News/AFP:

CAIRO (AFP) – Egyptian researchers are using DNA tests to discover the lineage of pharaoh king Tutankhamun, whose ancestry remains a mystery to Egyptologists, antiquities chief Zahi Hawass said on Monday.

The young king, whose mummy was found in a gold and turquoise sarcophagus by English archaeologist Howard Carter in 1922, ruled Egypt between 1333 and 1324 BC.

His ancestry has been as much a source of speculation as his abrupt end.

"Until now, we don't know who his father was. Was it Akhenaten or Amenhotep III," Hawass told reporters at a press conference.

Everything you need to know about the hottest topic in 
medicine, from big-league breakthroughs and new therapies to emerging health risks and the patients willing to take them.

For more than a decade, researchers have touted stem cells as the most promising advance in medicine since antibiotics. And this winter, when President Obama lifted the Bush administration's ban on federal funding for embryonic-stem-cell research, talking heads buzzed that his decision could bring scientists that much closer to cures — not just treatments — for conditions like heart failure, spinal-cord injuries and Alzheimer's disease. Biologists around the world toasted their new prospects with champagne. "Lifting the ban will free us up to use additional cell lines," says Jack Kessler, director of the Feinberg Neuroscience Institute at Northwestern University. "It's very important for science."
