The Apollo Hoax Theories
From The Independent:
It is 40 years since the drama of the Apollo 13 mission turned an aborted mission to the moon from potential disaster into a celebrated recovery.
But doubts still linger about the moon landings. 9/11 and Kennedy aside, no event in world history has generated quite so many conspiracy theories than the Apollo moon landings. Do they stand up? Here are the best reasons why it couldn’t have happened, and the rebuttals. Of course, you may disagree.

Meet The New Head Of DARPA
ARLINGTON, Va. — The Defense Advanced Research Projects Agency is different from other federal agencies. For one thing, the agency, known as Darpa, created the Internet (really). For another, it is probably the only agency ever to offer a $40,000 prize for a balloon hunt, a contest that was inspired by Regina Dugan, a 47-year-old expert in mine detection, who took over last summer as its director.
Dr. Dugan, who has a Ph.D. in mechanical engineering from the California Institute of Technology, is the first woman to be the director of Darpa, and those who know her say she has a knack for inspiring, and indeed insisting on, creative thinking.

Copyright Violation Alert Ransomware In The Wild
From ZNET:
A currently ongoing ransomware campaign is using a novel approach to extort money from end users whose PCs have been locked down.
By pretending to be the fake ICPP Foundation (icpp-online.com), the ransomware locks down the user’s desktop issuing a “Copyright violation: copyrighted content detected” message, which lists torrent files found on the infected PC, and forces the user to pay $400 for the copyright holder’s fine, emphasizing on the fact that “the maximum penalties can be five years in prison and up to $250,000 in fines.

Can Mozilla Be Bigger Than Facebook?
Mozilla has made a name for itself by taking on Microsoft Internet Explorer in the browser market, claiming as much as 30 percent of the global market with its open-source Firefox browser. Mozilla's second act, however, promises to be much more difficult, with increased competition from Microsoft but also from open-source competitors like Google Chrome.
What should Mozilla do next?

Pluto Joined By Up To 50 More Dwarf Planets
From Cosmos:
SYDNEY: The status of former planet Pluto has taken another blow, with new research suggesting up to 50 known objects may also meet the criteria to be dwarf planets.
To be labelled as a dwarf planet, an object must meet two criteria, as determined by the International Astronomical Union (IAU): they must be 'nearly round' and they must orbit the Sun.

Does Stress Feed Cancer?
From Scientific American:
A new study shows stress hormones make it easier for malignant tumors to grow and spread.
A little stress can do us good—it pushes us to compete and innovate. But chronic stress can increase the risk of diseases such as depression, heart disease and even cancer. Studies have shown that stress might promote cancer indirectly by weakening the immune system's anti-tumor defense or by encouraging new tumor-feeding blood vessels to form. But a new study published April 12 in The Journal of Clinical Investigation shows that stress hormones, such as adrenaline, can directly support tumor growth and spread.

Astronauts take 3rd, final spacewalk to finish installing tank; stuck valve threatens cooling.
A pair of spacewalking astronauts finished installing a fresh storage tank outside the International Space Station on Tuesday, but a stuck valve was threatening to jeopardize half of the cooling system.
No sooner had Rick Mastracchio hooked up the fluid valves for the new ammonia tank on the third and final spacewalk of shuttle Discovery's flight, then flight controllers encountered the valve trouble in a separate pressurizing unit.

Turning Planetary Theory Upside Down: Nine New Exoplanets Found, Some With Retrograde Orbits
From Science Daily:
ScienceDaily (Apr. 13, 2010) — The discovery of nine new transiting exoplanets has been announced at the RAS National Astronomy Meeting. When these new results were combined with earlier observations of transiting exoplanets astronomers were surprised to find that six out of a larger sample of 27 were found to be orbiting in the opposite direction to the rotation of their host star -- the exact reverse of what is seen in our own solar system.

Alzheimer's Self Test Works Surprisingly Well
A newly developed handwritten test designed to assess cognitive abilities in older adults could one day serve as a tool to help detect Alzheimer's disease in its early stages, new research suggests.
While previous pen-and-paper tests have been developed to help identify memory problems, most of them require a doctor to administer it. The new test, on the other hand, is self-administered.

2010 Forecast As Busy Year For Hurricanes
The Atlantic basin is facing a busier-than-usual hurricane season, in part because of record warm water in the ocean, according to the latest hurricane forecast.
Colorado State University's forecast, released Wednesday, calls for 15 named tropical storms this year in the Atlantic basin, which includes the Carribean and Gulf of Mexico. The team says eight will become hurricanes, with sustained winds reaching 74 mph. Four are expected to be major hurricanes — Categories 3, 4 or 5 — with maximum wind speeds of 111 mph or greater.

Instead Of "Arms Control", We Have "Cyber Controls"
Two researchers propose a novel form of "arms control" at a conference in Germany.
Cyber attacks can come from governments, terrorists, thieves, or bored high school students. This makes the cyber security equivalent of "arms control" difficult to achieve. But a pair of researchers yesterday proposed methods of deterrence that they believe could work in cyberspace.

Study: Spanking Kids Leads To More Aggressive Behavior
From Time Magazine:
Disciplining young children is one of the key jobs of any parent — most people would have no trouble agreeing with that. But whether or not that discipline should include spanking or other forms of corporal punishment is a far trickier issue.
The American Academy of Pediatrics (AAP) does not endorse spanking for any reason, citing its lack of long-term effectiveness as a behavior-changing tactic. Instead the AAP supports strategies such as time-outs when children misbehave, which focus on getting kids to reflect on their behavior and the consequences of their actions. Still, as many parents can attest, few responses bring about the immediate interruption of a full-blown tantrum like a swift whack to the bottom.

Take From ATM Malware Caper Exceeded $200,000
From Threat Level:
A Bank of America worker who installed malicious software on his employer’s ATMs was able to siphon at least $200,000 from the hacked machines before he was caught, according to a plea agreement he entered with prosecutors last week.
Rodney Reed Caverly, 37, was a member of the bank’s IT staff when he installed the malware, which instructed the machines to dispense free cash without creating a record of the transaction. The Charlotte, North Carolina, man made fraudulent withdrawals over a seven-month period ending in October 2009, according to prosecutors, who’ve charged him with one count of computer fraud.

Hawaiian Submarine Canyons Are Hotspots Of Biodiversity And Biomass For Seafloor Animal Communities
From Science Daily:
ScienceDaily (Apr. 11, 2010) — Underwater canyons have long been considered important habitats for marine life, but until recently, only canyons on continental margins had been intensively studied. Researchers from Hawaii Pacific University (HPU) and the Universtiy of Hawaii at Manoa (UHM) have now conducted the first extensive study of canyons in the oceanic Hawaiian Archipelago and found that these submarine canyons support especially abundant and unique communities of megafauna (large animals such as fish, shrimp, crabs, sea cucumbers, and sea urchins) including 41 species not observed in other habitats in the Hawaiian Islands.
