Giant Ribbon Discovered At Edge of Solar System 251

beadwindow writes "NASA's IBEX (Interstellar Boundary Explorer) spacecraft has made the first all-sky maps of the heliosphere and the results have taken researchers by surprise. The maps are bisected by a bright, winding ribbon of unknown origin: 'This is a shocking new result,' says IBEX principal investigator Dave McComas of the Southwest Research Institute. 'We had no idea this ribbon existed — or what has created it. Our previous ideas about the outer heliosphere are going to have to be revised.' Another NASA scientist notes, '"This ribbon winds between the two Voyager spacecraft and was not observed by either of them.'"

Scientists Write Memories Directly Into Fly Brains 137

TheClockworkSoul writes "Researchers at the University of Oxford have devised a way to write memories onto the brains of flies, revealing which brain cells are involved in making bad memories. The researchers said that in flies, just 12 brain cells were responsible for what is known as 'associative learning.' They modified these neurons by adding receptors for ATP, so that the cells activate in the presence of the chemical, but since ATP isn't usually found floating around a fly's brain, the flies generally behave just like any other fly. Most interestingly, however, is that the scientists then injected ATP into the flies' brains, in a form that was locked inside a light-sensitive chemical cage. When they shined a laser on the fly brains, the ATP was released, and the 'associative learning' cells were activated. The laser flash was paired with an odor, effectively giving the fly a memory of a bad experience with the odor that it never actually had, such that it then avoided the odor in later experiments. The researchers describe their findings in the journal Cell."

Fertility Clinic Bows To Pressure, Nixes Eye- and Hair-Color Screening 847

destinyland writes "A fertility service in L.A. and New York screens embryos for breast cancer, cystic fibrosis, and 70 other diseases — and lets couples pick the sex of their babies. But when their pre-implantation diagnostic services began including the baby's eye and hair color, even the Pope objected — and the Great Designer Baby Controversy began. '[W]e cannot escape the fact that science is moving forward,' the fertility service explained — before capitulating to pressure to eliminate the eye and hair color screenings."

How Do You Greet an Extraterrestrial? 803

The LA Times is running a story about Earth Speaks, a companion project to SETI, which focuses on how we would communicate with intelligent extraterrestrial life, should we happen to discover it. Far more effort has been devoted to searching for signals or a means to communicate than the question of what we might say once contact is established, and the folks at SETI have set up a website to gather opinions on what the best questions and statements are. "So far, the messages break down into a few distinct categories. Some people want to throw a block party to welcome the aliens to the neighborhood. Others, less trusting, would warn the aliens that we've got guns and know how to use them. Another group, possibly influenced by having seen too many movies, would have us hide under the bed until they go away. 'If we discover intelligent life beyond Earth, we should not reply — we should freeze and play dead,' wrote one contributor." What would you say first to an alien?

Windows Security and On-line Training Courses? 189

eggegick writes "My wife has taken a number of college courses over the last three years and many of the classes used on-line materials rather than books. The problem was these required IE along with Java, Active X and/or various plug-ins (the names of which escapes me), and occasionally I'd have to tweak our firewall to allow these apps to run. I don't think any of these training apps would work with Firefox. All of this made me cringe from a security point of view. Myself, I use Firefox, No-Script, our external firewall and common sense when using the web. I have a very old Windows 2000 machine that I keep up to date. To my knowledge, I've never had a virus or malware problem. Her computer is a relatively new XP machine, and at this point she feels her computer has something wrong. But now she prefers to use my old machine instead of hers since it seems to be more responsive. We plan to run the recovery disk on hers. Assuming the college course work applications were part of the cause, what recommendations do any of you have for running this kind of software? Is there a VMware solution that would work — that is, have a Windows image that is used temporarily for the course work and then discarded at the end of the semester (and how do you create such an image, and what does it cost?)."

From a Physicist's point of view, who ever publishes their paper about finding the Higgs first is going to be the one who is remembered an the one who would be a good candidate for a noble prize. Also the Fermilab physicists think that if they can find the Higgs they could get more funding for continued operation of the Tevatron.

Fannie Mae Worker Indicted For Malicious Script 325

dfdashh writes "A former Fannie Mae contractor has been indicted by a federal grand jury in Baltimore, MD for computer intrusion. He attempted to propagate a malicious script throughout the company's 4,000 servers. The DC Examiner has details of the incident: 'Had this malicious script executed, [Fannie Mae] engineers expect it would have caused millions of dollars of damage and reduced if not shutdown operations at [Fannie Mae] for at least one week. ... The virus was set to execute at 9 a.m. Jan. 31, first disabling Fannie Mae's computer monitoring system and then cutting all access to the company's 4,000 servers, Nye wrote. Anyone trying to log in would receive a message saying "Server Graveyard." From there, the virus would wipe out all Fannie Mae data, replacing it with zeros, Nye wrote. Finally, the virus would shut down the servers.'"

$29M To Start US Satellite Protection Program 74

coondoggie sends in a Network World piece that begins "The Air Force laid out $29 million in contracts this week to build space-based sensors that could detect threats or hazards and protect satellites in orbit. Assurance Technologies and Lockheed Martin Space Systems will split $20 million of the two-year contract that the Air Force says should ultimately demonstrate a viable sensing capability, as well as integration with other space systems to offer threat and hazard detection, assessment and notification ... The Air Force is looking to protect satellites from ground based lasers or anti-satellite missiles mostly."
