Mac OS X Leopard Debuts on Friday

Leopard is coming Friday, and people are already talking about its spots. Leopard is, of course, Apple's 10.5 update to Mac OS X that will have some 300 new features. The additions range from the useful, such as Time Machine's automatic backup of files, to the nice-to-have, such as being able to click on any address in Address Book to see it as a location in Google Maps. Boot Camp, which...

A New Key To Detecting Deadly Aortic Aneurysms

Scientists have discovered a way to use a simple blood test that may accurately detect thoracic aneurysm disease (TAA), which gives little warning and is almost always fatal if untreated. TAAs occur in the part of the aorta that passes through the chest. They can become huge without causing symptoms.

Could Electricity Grid Become A Type Of Internet?

In the future everyone who is connected to the electricity grid will be able to upload and download packages of electricity to and from this network. At least, that is one of the transformations the electricity grid could undergo. Due to an increasing demand for electricity it is important to include all possible energy options (including coal and nuclear energy) in the scenario development.

Hearing Changes How We Perceive Gender

Think about the confused feelings that occur when you meet someone whose tone of voice doesn't seem to quite fit with his or her gender. Neuroscientists focus on the brain's processing of such sensory information in a new study that concludes that hearing fundamentally changes visual experience. The researchers weigh in with findings that contribute to provocative evidence about multisensory...

Humans And Monkeys Share Machiavellian Intelligence

When it comes to their social behavior, people sometimes act like monkeys, or more specifically, like rhesus macaques, a type of monkey that shares with humans strong tendencies for nepotism and political maneuvering, according to new research. "After humans, rhesus macaques are one of the most successful primate species on our planet; our Machiavellian intelligence may be one of the reasons for...

Large Avian Flu Outbreaks More Likely To Involve Duck Meat Industry, Experts Find

Scientists predict that 73 percent of avian flu outbreaks in the UK would not spread beyond the initial infected farm, but larger outbreaks are more likely to involve the duck meat industry. Duck meat is more likely to cause large outbreaks of avian flu because ducks often do not show signs of the disease and as such delays diagnosis and control of the infection.

Verizon Wireless Drops FCC Open Access Suit

Verizon Wireless dropped its lawsuit this week seeking to block the open-access provisions of the FCC's auction of 700-MHz frequencies, according to several news reports. The action clears the road of a potential major obstacle to the auction, which requires that the commercial winner of some of the spectrum allow third-party devices and applications to work on the frequencies. It now...

Insider Domain Name Snatching Probed

The Internet's key oversight agency is investigating suspicions that insider information is being used to snatch desired domain names before an individual or business can register them. The Security and Stability Advisory Committee of the Internet Corporation for Assigned Names and Numbers termed the practice "domain name front running" and likened it to a stock broker buying or selling...

Can Razr2 Brighten Motorola's Future?

With a sleek design and an even sleeker advertising campaign, Motorola Inc. is banking on its new Razr2 cell phone to pump up anemic sales and provide a rosier future after a yearlong slump punctuated by back-to-back losses. After a first half that may have put CEO Ed Zander's future employment into question, the end of Motorola's rough patch may be in sight. "We indeed believe the worst...

Family History Of Alcoholism Linked To Love Of Sweets Among Women

Ad campaigns have capitalized on women's concerns about their waistlines and marketed cigarettes as a fat-free alternative to diminish sweet cravings and satisfy hunger. New findings show that women who smoke cigarettes are less sensitive to sweet taste than women who have never smoked, meaning they require higher concentrations of a sweet solution in order to detect sweet taste. Results also show...

New Way To Measure Ancient Ocean Temperatures Refined

A new thermometer measures seawater temperature dependent changes in the cell wall composition of archeabacteria. Climate reconstructions should always be based on comparisons of several types of parallel measurements to prevent unexpected scientific blunders, according to researchers. Determining the surface seawater temperatures in oceans and coastal waters is essential for the reconstruction of...

St. Bernard Study Shows Human-directed Evolution At Work

The St Bernard dog -- named after the 11th century priest Bernard of Menthon -- is living proof that evolution does occur, say scientists. Biologists at The University of Manchester say that changes to the shape of the breed's head over the years can only be explained through human-directed evolution through selective breeding, an artificial version of natural selection.

Understanding Differentiation In Human Embryonic Stem Cells

Researchers have used an existing genetic tool to study how human embryonic stem cells self-renew. The researchers used "knockdown" technology to reduce the expression, and plasmid vectors to increase the expression of oct4, a gene known to be necessary for self renewal. Both procedures resulted in differentiation, but with similar patterns, unlike mouse ES cells that differentiate into a...
