From Science Daily:

ScienceDaily (Mar. 9, 2009) — We know that lifespan can be extended in animals by restricting calories such as sugar intake. Now, according to a study published in the journal PLoS Genetics, Université de Montréal scientists have discovered that it's not sugar itself that is important in this process but the ability of cells to sense its presence.

Aging is a complex phenomenon and the mechanisms underlying aging are yet to be explained. What researchers do know is that there is a clear relationship between aging and calorie intake. For example, mice fed with half the calories they usually eat can live 40 percent longer. How does this work?

The 300-Year History of Internet Dating

From Live Science:

Almost everyone these days can name a couple they know that met on the Internet, though it wasn't so long ago that skimming the online personals for love was considered strange, even a bit desperate.

Taboo or not, the practice certainly isn't new. Personal ads have a history going back at least 300 years, according to a new book on the subject entitled "Classified: The Secret History of the Personal Column" (Random House Books, 2009).

Man Who Co-Discovered HIV Virus Accused Of Stealing Rights To Aids Cure

From The Telegraph:

A Nobel prize-winning French researcher who co-discovered the virus that leads to Aids but sparked controversy after his colleague said he had claimed all the glory, has now been accused of stealing the rights to a revolutionary invention that may provide a cure to the disease, it emerged yesterday.

Prof Luc Montagnier is locked in a legal battle with inventor Bruno Robert over the intellectual property rights to a technique whereby the Aids virus and other serious ailments, including Parkinson's and Alzheimer's disease, can be pinpointed by their electromagnetic "signatures".

The hope is that once identified, the diseases can be blocked or neutralised with an opposite electromagnetic signal.

The Secret Of Long Life? It's All Down To How Fast You React

Live long and prosper - if you have a speedy response time

From The Daily Mail:

People's reaction times are a far better indicator of their chances of living a long life than their blood pressure, exercise levels or weight, researchers have discovered.

Men and women with the most sluggish response times are more than twice as likely to die prematurely.

Edinburgh University and the Medical Research Council in Glasgow tracked 7,414 people nationwide over 20 years in a study which appears to confirm the adage that a healthy mind means a healthy body.

How Scientifically Accurate Is Watchmen?

WHY SO BLUE? Dr. Manhattan's color and (some of) his powers can be explained by quantum mechanics, thanks to your (self-proclaimed) "friendly neighborhood physics professor," Jim Kakalios. WARNER BROS. ENTERTAINMENT

From Scientific American:

The anticipated film Watchmen, based on the 1980s DC Comics 12-part comic book series (later adapted as a graphic novel), hits theaters tomorrow. Die-hard fans of the original publication may fret over its faithfulness to the series, but studio execs also worried about their movie's faithfulness to science. To set their minds at ease, they placed a call to Jim Kakalios, a physics professor at the University of Minnesota.

Kakalios, 50, began advising the film's makers in the summer of 2007 on everything from the quantum mechanics of Dr. Manhattan (one of the superheroes of the story) down to the details in the laboratories. "They wanted to know what was around the corner at the end of the long corridor, even if the audience wasn't going to see it," he says.

From The Christian Science Monitor:

EarthTalk: Scientists study ways to pull greenhouse gases out of our atmosphere, but the idea is controversial.

Q: What are some of the leading proposed technological fixes for staving off global warming, and how feasible are they?
– James Harris, Columbus, Ohio

A: While most of the world fixates on how to reduce the amount of carbon dioxide (CO2) and other greenhouse gases we emit into the atmosphere, scientists and engineers worldwide are working on various geoengineering technologies – many of which are highly theoretical – to mitigate global warming and its effects. Many scientists oppose using new technology to fix problems created by old technology, but others view it as a quick and relatively inexpensive way to help solve our most vexing environmental problem.

ScienceDaily (Mar. 8, 2009) — Despite the increased popularity of geek culture – movies based on comic books, videogames, virtual worlds – and the ubiquity of computers, the geek’s close cousin, the nerd, still suffers from a negative stereotype in popular culture.

This may help explain why women and minorities are increasingly shying away from careers in information technology, says Lori Kendall, a professor in the Graduate School of Library and Information Science at the University of Illinois at Urbana-Champaign.

The popular stereotype of the nerd as the sartorially challenged, anti-social white male hasn’t faded from our collective cultural consciousness, and is more prevalent than ever as a stock character in television shows, movies and advertisements.

NASA: Wednesday Night Shuttle Launch Is Official

The STS-119 Shuttle Discovery crew members gather on Launch Pad 39A at NASA's Kennedy Space Center in Florida in January 2009 before beginning their emergency egress training. After four launch delays, NASA says it now believes the space shuttle Discovery could be sent on a mission to the orbiting International Space Station (ISS) by mid-March. (AFP/NASA-HO)

From Yahoo News/AP:

CAPE CANAVERAL, Fla. – It's official: NASA has finally settled on a Wednesday night launch for space shuttle Discovery.

The flight to the international space station was originally set for mid-February, but was delayed four times because of concern over critical shuttle valves. On Friday, senior NASA managers meeting at Kennedy Space Center put the valve issue to rest for Discovery and cleared the shuttle for flight.

Seven astronauts will ride Discovery into orbit, taking with them one final set of solar wings for the space station.

Launch director Mike Leinbach said spirits are much higher now than they were when the flight kept being put off.

ScienceDaily (Mar. 8, 2009) — Two highly lethal viruses that have emerged in recent outbreaks are susceptible to chloroquine, an established drug used to prevent and treat malaria, according to a new basic science study by researchers at Weill Cornell Medical College in the Journal of Virology.*

The two henipaviruses that are the subject of the study -- Hendra Virus (HeV) and Nipah Virus (NiV) -- emerged during the 1990s in Australia and Southeast Asia. Harbored by fruit bats, they cause potentially fatal encephalitis and respiratory disease in humans, with a devastating 75 percent fatality rate. More recently, NiV outbreaks in Bangladesh involving human-to-human transmission have focused attention on NiV as a global health concern.

From Science News:

Bone and chemical analyses indicate horses were harnessed and even milked more than 5,000 years ago in central Asia

Central Asia’s vast grasslands hosted a prehistoric revolution in transportation, communication and warfare, thanks to the humble horse. Remains from Kazakhstan’s more than 5,000-year-old Botai culture have yielded the earliest direct evidence for domestication of these versatile beasts, scientists report.

The Botai people were hunter-gatherers who lived in large settlements for months or years. Their culture lasted from 5,600 to 5,100 years ago. Researchers have long suspected that the Botai rode domesticated horses while hunting for wild horses to eat but did not domesticate other animals or cultivate crops.

Daylight Saving Time Facts

Electric Time Company employee Walter Rodriguez cleans the face of an 84-inch (213-centimeter) Wegman clock at the firm's plant in Medfield, Massachusetts, on October 30, 2008. For most people in the United States, daylight saving time begins in the wee hours of March 8, 2009, with clocks turned forward one hour. Photograph courtesy AP Photo/Elise Amendola

From The National Geographic:

Daylight saving time in most of the United States starts this year in the early hours of March 8. The "spring forward" marks the second time the country has observed the switch in March rather than April since changes to the system were adopted in 2007.

Contrary to popular belief, no federal rule mandates that states or territories observe daylight saving time.

Most U.S. residents set their clocks one hour forward in spring and one hour back in fall. But people in Hawaii and most of Arizona—along with the U.S. territories of Puerto Rico, American Samoa, and the Virgin Islands—will do nothing. Those locales never deviate from standard time within their particular time zones.

From Discover:

By precisely mapping a volume of space 5 billion light-years in diameter, the Sloan telescope is answering some of the universe's biggest questions.

Located 9,200 feet above sea level, atop the Apache Point Observatory in Sunspot, New Mexico, the Sloan Digital Sky Survey telescope cannot match the incredibly sharp vision of the Hubble Space Telescope, which orbits above Earth’s blurring atmosphere. And, at a modest 2.5 meters (8 feet) across, the Sloan telescope’s main mirror cannot see the incredibly dim objects that the 10-meter (33-foot) Keck telescopes in Hawaii can. What the Sloan telescope does have in spades is a voracious appetite for sky—an appetite that is producing some of the most amazing discoveries in astronomy.

From New Scientist:

A SKELETON exhumed from a grave in Venice is being claimed as the first known example of the "vampires" widely referred to in contemporary documents.

Matteo Borrini of the University of Florence in Italy found the skeleton of a woman with a small brick in her mouth (see right) while excavating mass graves of plague victims from the Middle Ages on Lazzaretto Nuovo Island in Venice (see second image here).

At the time the woman died, many people believed that the plague was spread by "vampires" which, rather than drinking people's blood, spread disease by chewing on their shrouds after dying. Grave-diggers put bricks in the mouths of suspected vampires to stop them doing this, Borrini says.

First Successful Attempt To Breed Night Blooming And Day Blooming Flower

Electric Indigo is a cross between the Egyptian White Water Lily that blooms at night and a blue Australian lily Nympaea Barre Hellquist that flowers during the day

From The Telegraph:

The world's first cross between a day-blooming and night-blooming flower has been produced at the Royal Botanic Gardens in Kew.

The new hybrid called Electric Indigo is a cross between the Egyptian White Water Lily that blooms at night and a blue Australian lily Nympaea Barre Hellquist that flowers during the day.

The new water lily with bright blue petals is the first successful attempt at breeding day blooming and night blooming species since attempts began in 1852.

Lilies bloom during the night to take advantage of insects that will only come out night and pollinate the plant.

Propagator Carlos Magdalena, a horticulturalist who works at the gardens' tropical nursery, took pollen from the white night bloomer and placed it on the stigma of the day bloomer.

From Science Daily:

ScienceDaily (Mar. 6, 2009) — Naked mole rats resemble pink, wrinkly, saber-toothed sausages and would never win a beauty contest, even among other rodents. But these natives of East Africa are the champs for longevity among rodents, living nine times longer than similar-sized mice. Not only do they have an extraordinarily long lifespan, but they maintain good health for most of it and show remarkable resistance to cancer.

Researchers at The University of Texas Health Science Center at San Antonio are studying mechanisms that enable the prolonged good health and slowed aging of naked mole rats in their large colony at the university’s Barshop Institute for Longevity and Aging Studies. In the March 3 print edition of Proceedings of the National Academy of Sciences, the scientists report on another unusual feature of the animals — tissues of the naked mole rat are remarkably efficient at discarding damaged proteins and thereby maintaining stable, high-quality proteins.

Q&A: Mitchell Baker On The Future Of Firefox

Browsing The Future -- Newsweek

Mozilla's Firefox gave Microsoft a run for its money. What's next?

At least 18 percent of you already know what Firefox is, because you're using it to read this interview. (Or so says the statistics engine behind Newsweek.com, which tracks things like that.) For the unfamiliar, Firefox is a free Web browser that is built by coders around the world whose open-source work is organized by the Mozilla Corp. and its nonprofit parent, the Mozilla Foundation. Introduced in 2004 as an alternative to Microsoft's ubiquitous, but buggy, Internet Explorer, Firefox has been a force for innovation in the browser category, with improvements such as tabbed browsing and plug-ins that work on any operating system. Commissions from search engines appear to keep Mozilla awash in revenue for now ($75 million in 2007; the foundation has not released 2008 data), although the vast majority of that comes from a company, Google, that now has its own competing browser, Chrome. Mozilla's plans for 2009 include a new version of Firefox, which will focus on user-interface polish; an overhaul of Thunderbird, its e-mail client; and taking Firefox mobile. Mitchell Baker, the Mozilla Foundation's chairwoman, spoke to NEWSWEEK's Nick Summers and Barrett Sheridan about the challenges of making a browser for mobile phones, adapting to a socially networked universe and what she really thinks of Chrome and Internet Explorer.

From Science Daily:

ScienceDaily (Mar. 4, 2009) — NASA's Cassini spacecraft has found within Saturn's G ring an embedded moonlet that appears as a faint, moving pinprick of light. Scientists believe it is a main source of the G ring and its single ring arc.

Cassini imaging scientists analyzing images acquired over the course of about 600 days found the tiny moonlet, half a kilometer (about a third of a mile) across, embedded within a partial ring, or ring arc, previously found by Cassini in Saturn's tenuous G ring.

"Before Cassini, the G ring was the only dusty ring that was not clearly associated with a known moon, which made it odd," said Matthew Hedman, a Cassini imaging team associate at Cornell University in Ithaca, N.Y. "The discovery of this moonlet, together with other Cassini data, should help us make sense of this previously mysterious ring."

For the first time, scientists have watched as the Earth’s surface “heals” itself following the disruptive jolt of an earthquake, in this case, the 2003 temblor that devastated Bam, Iran.

The fault under the city erupted in a 6.6-magnitude quake on Dec. 26 that year, leveling the town and killing more than 26,000 people. But though devastation was evident, there was no clear fault mark at the surface.

"The fault slipped maybe 2 or 3 meters [6.5 to 10 feet] at depth, but at the surface, when colleagues of mine went out, they found some cracks, but the motion on those cracks is only about up to 25 centimeters [10 inches] or less," said one of the scientists who studied the quake, Eric Fielding of Caltech. "We have some layer of material near the surface that's behaving differently from the fault at depth."

China is speeding up plans to launch and operate a space station in Earth orbit and turning over the project to military control, according to reports from the official Chinese news agency Xinhua and SpaceflightNow.com.

The 8.5-ton laboratory, called Tiangong -- Chinese for "heavenly palace" -- is slated for launch before the end of next year. Its first crew would arrive in 2011.

"The People's Liberation Army's General Armament Department aims to finish systems for the Tiangong-1 mission this year," the Chinese government said in an official statement.

The design was unveiled during a nationally televised Chinese New Year broadcast, writes Spaceflightnow's Craig Covault.

My Comment: So much for not militarizing space. This is an acceleration of a program that many thought was years from fruition.

Surprise, it is happening sooner than what was expected.

Mobile Phone Use Explodes As 60% Of The World's Population Signs Up For A Handset

The United Kingdom was ranked 10th most advanced country in using information and communications technology. It was judged on criteria including infrastructure, broadband coverage and literacy levels

From The Daily Mail:

Mobile phone use has exploded in the last seven years, according to a U.N report.

The number of global subscriptions quadrupled from around 1billion in 2002 to 4.1billion at the end of last year.

The sudden surge in uptake of mobile phones is most marked in developing countries where they are now an invaluable tool among the world's poor.

In Africa 28 per cent of the population now has a mobile phone, compared to just two per cent in 2000.

Hubble Captures Cosmic Tug-Of-War Between Three Turbulent Galaxies

The three tussling galaxies are part of the Hickson Compact Group 90,
which is 100million light years away

From The Daily Mail:

A dramatic Hubble image has captured three galaxies locked in a gravitational tug-of-war that may lead to one of them being ripped apart.

It is likely the outcome has long since been decided, as the epic life or death battle is in the constellation of Piscis Austrinus, or Southern Fish, 100 million light-years away.

The new picture from the Advanced Camera for Surveys on the Hubble Space Telescope allows astronomers to view the movement of gases from galaxy to galaxy, revealing the intricate interplay among them.

How Good Are You At Internet Search?

From The Wall Street Journal:

Microsoft’s efforts to catch Google in Internet search may not just hinge on its ability to build a better search engine. It may depend on how good people are at using search engines.

In an internal memo published on All Things D, a Microsoft search executive wrote that the company is ready to test a new search engine, codenamed “kumo.” He then outlined the problem that the new search engine is supposed to address:

“In spite of the progress made by search engines, 40% of queries go unanswered; half of queries are about searchers returning to previous tasks; and 46% of search sessions are longer than 20 minutes. These and many other learnings suggest that customers often don’t find what they need from search today.”

Here's What Killed Your 401K

From Wired News:

A year ago, it was hardly unthinkable that a math wizard like David X. Li might someday earn a Nobel Prize. After all, financial economists—even Wall Street quants—have received the Nobel in economics before, and Li's work on measuring risk has had more impact, more quickly, than previous Nobel Prize-winning contributions to the field. Today, though, as dazed bankers, politicians, regulators, and investors survey the wreckage of the biggest financial meltdown since the Great Depression, Li is probably thankful he still has a job in finance at all. Not that his achievement should be dismissed. He took a notoriously tough nut—determining correlation, or how seemingly disparate events are related—and cracked it wide open with a simple and elegant mathematical formula, one that would become ubiquitous in finance worldwide.

For five years, Li's formula, known as a Gaussian copula function, looked like an unambiguously positive breakthrough, a piece of financial technology that allowed hugely complex risks to be modeled with more ease and accuracy than ever before. With his brilliant spark of mathematical legerdemain, Li made it possible for traders to sell vast quantities of new securities, expanding financial markets to unimaginable levels.

Square Root Day Revelers To Party Like It's 3/3/09

From CNET:

Count on Tuesday's alignment of the calendar to add some excitement to the lives of at least a few math geeks.

Tuesday is Square Root Day, a rare holiday that occurs when the day and the month are both the square root of the last two digits of the current year. Numerically, March 3, 2009, can be expressed as 3/3/09, or mathematically as √9 = 3, or 3² = 3 × 3 = 9.

Dolphin-Inspired Man-Made Fin Works Swimmingly

SWIM FIN INSPIRED BY DOLPHINS: Lunocet users have already hit about eight miles (13 kilometers) per hour, nearly twice as fast as Olympic Gold Medal swimmer Michael Phelps at his speediest. COURTESY OF LOMERANGER

From Scientific American:

Lunocet swimmers have already hit about eight miles per hour, almost twice the speed of Michael Phelps at his fastest.

The human body does many things well, but swimming isn't one of them. We're embarrassingly inefficient in the water, able to convert just 3 or 4 percent of our energy into forward motion. (Even with swim fins, we're only 10 to 15 percent more efficient.) But a new, dolphin-inspired fin promises to fuel the biggest change in human-powered swimming in decades, putting beyond-Olympian speeds within reach of just about anyone.

Ancient Supernovae May Be Recorded In Antarctic Ice

From The New Scientist:

A newly examined ice core shows what may be the chemical traces of supernovae that exploded a thousand years ago.

Yuko Motizuki of the RIKEN research institute in Wako, Japan, and colleagues analysed the nitrate content of an ice core drilled at Dome Fuji station in Antarctica. Nitrate is produced in the atmosphere by nitrogen oxides, which in turn should be created by the gamma radiation from a supernova.

Motizuki's group found high nitrate concentrations in three thin layers about 50 metres deep. Because snow gradually builds up into layers of ice, depth indicates age.

Hunting For Earths

Hundreds of solar systems have been picked out of the sky; all harbor exoplanets the size of Jupiter or larger, but so far other Earths have eluded astronomers. NASA's Kepler space telescope, however, is expected to give the first reliable count of any habitable planets. Credit: NASA/NRC Canada/C. Marois et al.

From Discovery:

A new NASA mission in search of exoplanets has experts weighing in on whether we'll find life off Earth.

Earth seems so alone, drifting through space -- but are there other Earth-like worlds out there capable of supporting life, and if so how many are there nearby?

To answer that question once and for all, NASA is sending the Kepler telescope into space. Once there, it will stare down thousands of stars to seek out the slightest glimpse of a small, rocky world like our own.
