Article: Unique moon may partner Sedna?| New Scientist: "Now a UK team has shown that if Sedna has a moon, it must be more like a gigantic, extinct comet than a planetary body.
Assuming the moon exists, Chandra Wickramasinghe of Cardiff University in the UK and colleagues calculated its maximum possible reflectivity on the basis that the space telescopes have been unable to see it. 'If there is a moon, it has to be the darkest object in the solar system,' Wickramasinghe says."

Article: DNA technique protects against 'evil' emails?| New Scientist: "A technique originally designed to analyse DNA sequences is the latest weapon in the war against spam. An algorithm named Chung-Kwei (after a feng-shui talisman that protects the home against evil spirits) can catch nearly 97 per cent of spam.
Chung-Kwei is based on the Teiresias algorithm, developed by the bioinformatics research group at IBM's Thomas J Watson Research Center in New York, US. Teiresias was designed to search different DNA and amino acid sequences for recurring patterns, which often indicate genetic structures that have an important role."

Everything Space: Astronomy and Space News“There are thought to be millions of these WIMPs going through our bodies every second,” Newburg adds. “Because they are weakly interacting, detectors designed to look for them might detect only a few a day. The reason we think these WIMPs exist is that we see the effects of some unknown and unseen mass pulling at the stars of the Milky Way through gravity. Though each WIMP is very small, there are so many of them that their mass accounts for 90% of the mass in our galaxy. It is quite extraordinary to me that we might live in a sea of these barely-detectable particles, and that we scientists see this as the most likely explanation for our observations of the heavens.”
“Because the Earth is much more dense than the Milky Way galaxy, the WIMPs have very little effect on the gravity we feel, and as far as we know our lives are not directly affected by the tiny particles.”

InformationWeek > Database Mixup > Terror List Ties Up Sen. Kennedy > August 20, 2004: "WASHINGTON (AP) -- A top Homeland Security official has apologized to Sen. Edward M. Kennedy, who was stopped at airports because a name similar to his appeared on the government's no-fly list of terror suspects.
'If they have that kind of difficulty with a member of Congress, how in the world are average Americans, who are getting caught up in this thing, how are they going to be treated fairly and not have their rights abused?' Kennedy asked Homeland Security undersecretary Asa Hutchinson.
The Massachusetts Democrat said he'd been misidentified on the watch list when he tried to board airliners between Washington and Boston. Kennedy said he was stopped five times as he tried to board US Airways shuttles because a name similar to his appeared on a list or his name popped up for additional screening."

Universe Today - Armadillo Aerospace Rocket Destroyed
Universe Today - Armadillo Aerospace Rocket Destroyed: "Summary - (Aug 10, 2004) Another X Prize contender's rocket crashed over the weekend. Armadillo Aerospace's lead engineer and funder John Carmack reported that their prototype rocket ran out of fuel on a test flight and crashed shortly after takeoff. The $35,000 hydrogen peroxide-powered 'Black Armadillo' lifted off from the launch pad and then ran out of fuel 180 metres (590 feet) into the air; it crashed into the ground and was completely destroyed. The team hopes to be flying again in September with a completely new vehicle."
T. rex owes its giant size to the ultimate teenage growth spurt
T. rex owes its giant size to the ultimate teenage growth spurt: "For the first time, scientists have determined the lifelong growth pattern for the Tyrannosaurus rex. T. rex reached its massive adult size due to an extraordinary growth spurt that stretched from about 14 to 18 years of age. Furthermore, the surge was followed by about 10 years of little or no growth as an adult, according to a study that will be the cover story of Nature Thursday, Aug. 12, 2004."
