From Cosmos:

HUNTSVILLE, USA: The ribbon of particles at the edge of the Solar System "shocked" NASA researchers when it was discovered last year. Now they say it is a reflection off a strong galactic magnetic field, and holds the clues to the future of the Solar System.

In October last year, NASA's IBEX (Interstellar Boundary Explorer) spacecraft made the first all-sky maps of the heliosphere - the bubble of magnetism that springs from the Sun and surrounds our Solar System.

The result was a map bisected by a bright, winding ribbon of unknown origin. At the time, NASA researchers called it a "shocking result" and puzzled over its origin.

Navy Pledges Green Strike Group By 2012

The Navy is Going Green The Navy will demonstrate a Green Strike Group, like the George Washington Carrier Strike Group pictured here, by 2012; the group will run on biofuels and nuclear power rather than fossil fuels.

From Popular Science:

Militaries have a tough, often messy job to do, and as such taking steps to polish their green credentials generally isn’t a high priority. But the potential cost savings – not to mention the tactical advantages – of going green are not lost on U.S. Armed Forces’ top brass. The Army has pursued “zero footprint” base camps, and the Air Force is looking into a variety of alternative propellants that could be turned into jet fuel. Now the Navy is going green, signing a memorandum of understanding with the USDA to demo a Green Strike Group of biofuel- and nuclear-powered vessels by 2012.

My Comment: Political correctness running amok .... but I will concede that the search for alternative fuels and energy is a valid one, and one that may produce huge savings in the future (maybe).

Obama Aims To Ax Moon Mission

From Orlando Sentinel:

NASA's plans to return astronauts to the moon are dead. So are the rockets being designed to take them there — that is, if President Barack Obama gets his way.

When the White House releases his budget proposal Monday, there will be no money for the Constellation program that was supposed to return humans to the moon by 2020. The troubled and expensive Ares I rocket that was to replace the space shuttle to ferry humans to space will be gone, along with money for its bigger brother, the Ares V cargo rocket that was to launch the fuel and supplies needed to take humans back to the moon.

There will be no lunar landers, no moon bases, no Constellation program at all.

Science Chief John Beddington Calls For Honesty On Climate Change

The IPCC's 2007 report that the glaciers would disappear by 2035 has exposed a wider problem with the way that some evidence was presented

From Times Online:

The impact of global warming has been exaggerated by some scientists and there is an urgent need for more honest disclosure of the uncertainty of predictions about the rate of climate change, according to the Government’s chief scientific adviser.

John Beddington was speaking to The Times in the wake of an admission by the Intergovernmental Panel on Climate Change (IPCC) that it grossly overstated the rate at which Himalayan glaciers were receding.

We Will Find 'Twins Of Earth' This Year, Says Astronomer Michel Mayor

From Times Online:

Scientists will have detected the first truly Earth-like planet outside the solar system by the end of the year, one of the world’s leading astronomers predicted yesterday.

Professor Michel Mayor, of Geneva University, who led the team that discovered the first extrasolar planet (or exoplanet) in 1995, said he was confident that a planet of a similar size and composition to Earth would be found in the near future.

Addressing a Royal Society conference to mark the 50th anniversary of the Search for Extra-Terrestrial Intelligence (SETI) programme, he said: “The search for twins of Earth is motivated by the ultimate prospect of finding sites with favourable conditions for the development of life. We’ve entered a new phase in this search.”

Ambassador Or Slave? East Asian Skeleton Discovered In Vagnari Roman Cemetery

Researchers announced that the skeleton of a man, seen here, has DNA that indicates an East Asian ancestry. Sadly he may have been a slave. His sole surviving grave good, a single pot, can be seen on the far left. A person was buried on top of him and appears to have been given more grave goods. Photo courtesy Professor Tracy Prowse.

From The Independent:

A team of researchers announced a surprising discovery during a scholarly presentation in Toronto last Friday. The research team, based at McMaster University in Hamilton, Canada, has been helping to excavate an ancient Roman cemetery at the site of Vagnari in southern Italy. Led by Professor Tracy Prowse, they’ve been analyzing the skeletons found there by performing DNA and oxygen isotope tests.

The surprise is that the DNA tests show that one of the skeletons, a man, has an East Asian ancestry – on his mother’s side. This appears to be the first time that a skeleton with an East Asian ancestry has been discovered in the Roman Empire.

However, it seems like this contact between east and west did not go well.

Pentagon Tests A Global Internet Routing System Via Satellite

Atlas Launch Cisco's space Internet router launched aboard an Atlas 5 rocket on November 23, 2009. ULA/Pat Corkery

From Popular Science:

Communication satellites have traditionally acted as transfer points for data beamed up from the ground. But the first commercial satellite with its own Internet router could eliminate the usual satellite-relay transfer lag and more flexibly handle voice, video and data communications for U.S. and NATO military forces anywhere around the world. The U.S. Department of Defense plans to kick off a three-month demo of the space technology this week, according to Aviation Week's Ares Defense Blog.

My Comment: With the growth of UAV and other robotic systems/platforms continuing at a rapid rate, having the proper (and secure) communication platforms will become even more essential in the years to come. I can only presume that this "space internet router" is just one more vital piece of technology to make all of this work.

From Time Magazine:

By the summer of 2009, shortly after the H1N1 flu pandemic had first emerged, there was a waiting list for the first several million doses of the forthcoming new flu vaccine. At the head of the line, naturally, were the world's richest nations. "Again we see the advantage of affluence," said Margaret Chan, the head of the World Health Organization (WHO), at a news conference on July 14. "Again we see access denied by an inability to pay." Describing H1N1 as "entirely new and highly contagious," Chan scolded rich countries at the time for hoarding the "lion's share" of the global H1N1-vaccine supply.

From The Independent:

The rich and famous people of ancient Egypt lived a decadent lifestyle with fine wine, sex, high fashion, and plenty of partying. How do they compare with their equivalents today - the modern western celebrity set?

The main differences might be regarding who were the richest people then, and who are the richest people now. In ancient Egypt the pharaoh was at the top of the ‘pyramid’ and his family, noble people who owned land, and the priests came after. Scribes, architects and doctors were well off, and skilled craftsmen also had many privileges.

What Happens In Sex Rehab?

Gentle Path facility in Hattiesburg, Miss.

From Time Magazine:

The calls for Tiger Woods to get help did not go unheeded: on Jan. 16, after weeks of sordid allegations regarding his extramarital affairs, Radaronline.com reported that Woods had enrolled in the Gentle Path program at Pine Grove Behavioral Health and Addiction Services, in Hattiesburg, Miss., to be treated for sex addiction. Local television stations later confirmed the story.

Few people know what actually happens at sex rehab. While those who treat it say sex addiction is a disease like any other compulsion, the field is in its infancy: there is virtually no research on it compared to the vast resources on drug or alcohol addiction. "You look at ways that your behavior has made your life unmanageable. That's really the question," says Benoit Denizet-Lewis, author of America Anonymous: Eight Addicts in Search of a Life, who has been treated for sex addiction himself. "That often differentiates a sex addict from a nonsex addict."

The U.S. Missile Defense Agency has released a video of this futuristic system in action, tracking and engaging a test missile fired from San Nicolas Island off the California coast. While the video might come off just a bit anti-climactic, with no dramatic explosion to cap off the laser blast, it does prove one key thing: the system, at least if the video is to be believed, actually works.

Mozilla Leader Worries About Internet Limits

From Yahoo News/AP:

MUNICH, Germany (AP) -- The leader of the Mozilla Project, whose Firefox Web browser now has 350 million users, said Sunday that she is concerned that legal restrictions could limit Internet expansion.

Mitchell Baker said she worried about "the increase in laws that make it difficult to run an open network," especially rules about content.

"You suddenly become liable for anything that gets downloaded, whether it's legal or not," she said. "If you said to a municipality, if you build a road, you have to guarantee nothing illegal happens on it -- that's what's happening on the Internet now. So that's the kind of regulatory disruption that's going to have some long-term consequences."

From USA Today:

WASHINGTON — Still hoping for that Jetsons future?

Ruh-roh, as the Jetsons' dog, Astro, might put it.

Just six years ago, President Bush laid out a vision of space exploration that harked back to NASA's halcyon days built on astronauts as explorers. Bush wanted to sling them from low Earth orbit to a base on the moon and then, perhaps, on to a first manned landing on another planet, Mars.

But that was before huge federal deficits arrived, public support failed to show, and unmanned explorers scored successes — namely the Hubble telescope and Mars rovers Spirit and Opportunity, which are still sending back signals years after they were expected to expire.

The Intricate Beauty Of The Solar Corona

(Click Image to Enlarge)

From Discovery News:

The solar corona is the magnetically dominated atmosphere of the sun, reaching millions of miles into space. Paradoxically, the corona is many times hotter than the solar 'surface' (the photosphere) and solar physicists are currently trying to understand why this is the case.

The photosphere has an average temperature of approximately 6000 degrees Celsius, whereas the corona can be millions of degrees Celsius. This is analogous to the air surrounding a hot light bulb being hotter than the bulb itself; in reality, the air surrounding the bulb is cooler than the bulb's glass surface, and it gets cooler the further you move your hand away.

Comet Storm Split Destiny Of Jupiter's Twin Moons

Comet strikes may have warmed Ganymede enough for its

From New Scientist:

Heavy pummelling by icy comets could explain why Jupiter's two biggest moons – apparently close kin – look so different inside.

At first glance, Ganymede and Callisto are virtually twins. The colossal moons are similar in size and mass, and are a roughly 50:50 mixture of ice and rock.

However, visits by the Galileo spacecraft beginning in 1996 tell a different story. Ganymede's interior boasts a solid rock core surrounded by a thick layer of ice, while ice and rock are still mingled in parts of Callisto. That suggests Callisto was never warm enough for its ice to melt and allow all of its rock to fall to the centre and form a core.

According to a new analysis, one out of five Web users still decides to leave the digital equivalent of a key under the doormat: they choose a simple, easily guessed password like “abc123,” “iloveyou” or even “password” to protect their data.

“I guess it’s just a genetic flaw in humans,” said Amichai Shulman, the chief technology officer at Imperva, which makes software for blocking hackers. “We’ve been following the same patterns since the 1990s.”

Neurons Developed From Stem Cells Successfully Wired With Other Brain Regions In Animals

This is a single stem cell-derived neuron that has migrated away from the transplantation site in the cortex and grown into a mature neuron. The blue stain shows the nuclei of the endogenous neural cells in this part of the brain. (Credit: Courtesy, with permission: Weimann et al. The Journal of Neuroscience 2010.)

From Science Daily:

Science Daily (Jan. 24, 2010) — Transplanted neurons grown from embryonic stem cells can fully integrate into the brains of young animals, according to new research in the Jan. 20 issue of The Journal of Neuroscience.

Healthy brains have stable and precise connections between cells that are necessary for normal behavior. This new finding is the first to show that stem cells can be directed not only to become specific brain cells, but to link correctly.

Why Human Blood Drives Mosquitoes Wild

From Live Science:

When the time came for chemical ecologist Walter Leal to test whether humans make a natural odor that attracts mosquitoes, Leal himself was the first to volunteer.

"I measured my own levels," Leal said. "I thought I would set a good example. If you do it first, then others won't be scared."

In truth, there was little if any reason to be frightened. The scientists were looking only for the substance itself, not trying to find out whether the compound would lure the insects into a blood meal. And they found it — nonanal, a substance made by humans and birds that creates a powerful scent that Culex mosquitoes find irresistible.
