Trick or Tweet? Malware Abundant in Twitter URLs
From Threat Level/Wired:
As many as one in every 500 web addresses posted on Twitter lead to sites hosting malware, according to researchers at Kaspersky Labs who have deployed a tool that examines URLs circulating in tweets.
The spread of malware is aided by the popular use of shortened URLs on Twitter, which generally hide the real website address from users before they click on a link, preventing them from self-filtering links that appear to be dodgy.

Russians To Ride A Nuclear-Powered Spacecraft To Mars
From Christian Science Monitor:
President Dmitry Medvedev says Russia will spend $600 million on a nuclear-powered spacecraft to take men to Mars, and beyond. Is it safe?
MOSCOW – A nuclear-powered spaceship that can carry passengers to Mars and beyond may sound like science fiction.
But Russian engineers say they have a breakthrough design for such a craft, which could leapfrog them way ahead in the international race to build a manned spacecraft that can cover vast interplanetary distances.
They claim they’ll be ready to build one as early as 2012.

Hubble Captures Sparkling ‘Jewel Box’ Star Cluster
From Wired Science:
This stunning image of the Kappis Crucis Cluster, nicknamed the “Jewel Box,” was one of the last gifts from a retiring camera on the Hubble Space Telescope.
Just before NASA brought the Wide Field Planetary Camera 2 back to Earth in mid-2009, it snapped this photo of the core of the NGC 4755 star cluster, the first comprehensive image of an open galactic cluster taken in multiple wavelengths. Using seven different filters, Hubble captured the Jewel Box cluster in far ultraviolet to near-infrared light. The different colors of the stars — from pale blue to bright ruby red — result from their differing intensities at various ultraviolet wavelengths.
5 Frightening (But True) Space Stories
From Discover Magazine:
There's nothing like a good horror story in space*. I grew up watching Sigourney Weaver outsmart xenomorphs in her underwear and subsequently spent a little too much time reading the likes of Stephen King's "I am the Doorway," H.P. Lovecraft's "In the Walls of Eryx" and John Steakley's "Armor."
As a result, it's hard for me to read about space exploration without thinking of about its darker possibilities -- and I don't just mean aliens and distant Hell worlds. Leaving Earth's atmosphere is a dangerous endeavor and, major tragedies aside, there have been a number of smaller terrifying, grotesque and absurd episodes to come out of it. So if you'll allow me to serve as your cosmic Crypt Keeper for a few minutes, I thought I'd run though a few of the ones that get under my skin.

Robins Can See Earth's Magnetic Field
From The Telegraph:
Robins can 'see' the Earth's magnetic field which allows them to navigate, scientists believe.
The information, relayed to a specialised light-processing region of the brain called ''cluster N'', helps the robin find its way on migration flights.
Experts know birds possess an internal magnetic compass, but there is disagreement about what form it takes.

Blast From The Past: Most Distant Stellar Object Gives Clues About Early Universe
From Science Daily:
Science Daily (Oct. 29, 2009) — Astronomers using the National Science Foundation's Very Large Array (VLA) radio telescope have gained tantalizing insights into the nature of the most distant object ever observed in the Universe -- a gigantic stellar explosion known as a Gamma Ray Burst (GRB).
The explosion was detected on April 23 by NASA's Swift satellite, and scientists soon realized that it was more than 13 billion light-years from Earth. It represents an event that occurred 630 million years after the Big Bang, when the Universe was only four percent of its current age of 13.7 billion years.

Why We Carve Pumpkins, Not Turnips
From Live Science:
Big orange veggies are pretty strange as far as holiday symbols go, but there are actual historical reasons that we carve pumpkins every Halloween.
Like Halloween itself, the display and carving of pumpkins – from the lanterns placed inside to the scary faces we pick – has pagan origins that morphed with the passage of time as well as the crossing of an ocean.
The modern traditions of Halloween have roots in a Celtic holiday called Samhain, which was celebrated throughout Western Europe (but especially Ireland) every Oct. 31 to mark the end of the summer and the final harvest.

Tuna Ban 'Justified' By Science
From The BBC:
Banning trade in Atlantic bluefin tuna is justified by the extent of their decline, an analysis by scientists advising fisheries regulators suggests.
The International Commission for the Conservation of Atlantic Tunas' (ICCAT) advisers said stocks are probably less than 15% of their original size.
The analysis has delighted conservation groups, which have warned that over-fishing risks the species' survival.
ICCAT meets to consider the report in 10 days' time.

‘Impossible’ Device Could Propel Flying Cars, Stealth Missiles
The Emdrive is an electromagnetic drive that would generate thrust from a closed system — “impossible” say some experts.
To critics, it’s flat-out junk science, not even worth thinking about. But its inventor, Roger Shawyer, has doggedly continued his work. As Danger Room reported last year, Chinese scientists claimed to validate his math and were building their own version.
My Comment: If this is even remotely possible, warfare as we know it will completely change. Again .... it is a big if.

Pilots Distracted By Laptops? Not In Cockpits Of The Future.
From Christian Science Monitor:
Automated flight controls under research may be able to sense how alert pilots are. It’s one way science could help prevent mistakes like the one made by the Northwest pilots who overflew Minneapolis by 150 miles.
As two Northwest pilots ponder their futures – minus their pilot licenses – researchers are developing new approaches for keeping pilots on their toes on long flights.
It’s part of a larger effort to improve air safety over the next decade or two with the US Federal Aviation Administration’s “NextGen” air-traffic control system.

From Science Daily:
Science Daily (Oct. 28, 2009) — Bad drivers may in part have their genes to blame, suggests a new study by UC Irvine neuroscientists.
People with a particular gene variant performed more than 20 percent worse on a driving test than people without it -- and a follow-up test a few days later yielded similar results. About 30 percent of Americans have the variant.
"These people make more errors from the get-go, and they forget more of what they learned after time away," said Dr. Steven Cramer, neurology associate professor and senior author of the study published recently in the journal Cerebral Cortex.

40 Years Ago: The Message that Conceived the Internet
On Oct. 29, 1969, UCLA student Charles Kline sent the first message over the ARPANET, the computer network that later became known as the Internet. Though only the "l" and "o" of his message ("login") were successfully transmitted, the interactive exchange ushered in a technological revolution that has — as anyone alive long enough to witness the shift knows — revolutionized human interaction.
