The European Space Agency‘s Mars Express spacecraft has discovered ice deposits in the south pole of Mars that are larger than the state of Texas.

Scientists say that there is enough water in the deposits to cover the entire planet with up to 36 feet of water if the ice was to melt. Some sections of the ice deposits are up to 2.3 – 2.5 miles deep. The ice is composed of carbon dioxide, a little bit of dust, and water (90 percent of the water is estimated to be frozen).

What has caught the attention of the scientists working on the Mars Express project is that this may help reveal whether or not there is any (microbial) life within the ice.

Another perplexing question that scientists are trying to solve is what happened to all the water that produced all the channels on the surface of Mars.

Jeffrey Plaut, who is from NASA’s Jet Propulsion Laboratory in Pasadena, California and who is also leading the study, noted that, “We have this continuing question facing us in studies of Mars, which is: where did all the water go? Even if you took the water in these two (polar) ice caps and added it all up, it’s still not nearly enough to do all of the work that we’ve seen that the water has done across the surface of Mars in its history.”

Currently, only 10 percent of the water is remaining and is located at the poles of Mars. It has been suggested that some of the remaining 90 percent of the water that disappeared could either be underground or could have simply left the atmosphere into space.

Toyota announced on Friday that it will recall around 17,000 Lexus vehicles in response to risks of the fuel tank in the cars leaking after a collision.

The Lexus HS 250h model was subjected to the recall following a US National Highway Traffic Safety Administration (NHTSA) investigation. Despite previously passing Toyota safety inspections, the conclusions of an NHTSA sub-contracted investigator were that; when the vehicles in question collided with an object at more than fifty-miles-per hour, more than 142 grams of fuel, the maximum allowed by US law, leaked from the crashed car.

According to Toyota, further tests did not show any additional failure of the fuel tank.

In response to the findings, Toyota issued a recall of all affected vehicles, since the company had no solution immediately available. The recall includes 13,000 cars already sold, as well as another 4,000 still at dealerships.

Toyota says it plans to conduct further tests to determine the cause of the leak. A Toyota spokesman, Brian Lyons, said that the company was “still working to determine what the root cause of the condition is.” It’s still unclear when exactly the recall will take place, or when dealerships will be allowed to sell this model again. Lyons said that Toyota is “working feverishly to get this resolved as soon as possible.”

Toyota isn’t aware of any accidents stemming from the leaking fuel tank in the affected vehicles, first introduced in the summer of 2009.

The United States House of Representatives has passed The Affordable Health Care for America Act or HR 3962, a bill which would ensure that 95–96% of US citizens receive affordable health care.

HR 3962 was passed with 220 yeas and 215 nays. Democrats in the house needed at least 218 votes to pass the bill. 39 Democrats voted against the bill, which contained the Stupak amendment. This amendment curtailed women’s abortion rights. One Republican, Representative Joseph Cao of Louisiana, voted for the bill.

The US Senate has drafted their own health care bill, S. 1679. It is not yet known when the Senate will vote on their version of the bill, but in the end both versions must be merged into one with both the House and Senate voting again.

The health care program associated with HR 3962 is estimated to cost over US$1 trillion over ten years, according to the Speaker of the House Nancy Pelosi, who states that it will result in “[…] not one dime added to the deficit.”

US President Barack Obama says that he is “confident” that the Senate will be able to come to an agreement and pass a completed bill. Obama added that he hopes to sign a “comprehensive health insurance reform into law by the end of the year.”

Los Angeles, California —A simple saliva test can predict whether children will get cavities, how many cavities they will get and which teeth are most vulnerable.

Developed by researchers at the University of Southern California in Los Angeles, the test quantifies the genetic component of tooth decay, spotting the risk when something can be done about it.

“When we apply this to young children, it allows us to predict what might be their future caries history—the number of cavities that they’ll get by, say, their late 20s or early 30s,” says researcher Paul Denny.

Called the Caries Assessment and Risk Evaluation (CARE) test, the test measures the relative proportions in saliva of different types of sugar chains called oligosaccharides. The same sugar chains are present on tooth surfaces.

The effect of sugar chains on teeth’s resistance to disease is analogous to the effect of “good” and “bad” cholesterol on blood vessels. “Good” sugar chains tend to repel bacteria that cause cavities while “bad” allow bacteria to bond to teeth and start the decay process. Unlike cholesterol, however, sugar chain makeup in humans is 100% genetically determined.

Denny and colleagues have found that the sugar chain makeup in saliva can predict a child’s future cavity history to plus or minus one cavity with greater than 98% confidence.

The findings suggest that in developed areas of the modern era genes play a more significant role in tooth decay than in former times or third world nations where gross malnutrition and negligent oral hygiene held the greatest impact on dental health.

The 10.10 version of Ubuntu (codename Maverick Merkaat), a free operative system is to be released in the next few days. French Wikinews contributor Savant-fou (Baptiste) has interviewed Fabrice (fabrice_sp on Ubuntu), an Ubuntu’s MOTU (Master Of The Universe), member of the development team of the operative system.

Ubuntu is a computer operating system, based on Debian, which is created collaboratively by thousands of people. There are three official Ubuntu versions: Ubuntu Desktop Edition (for desktop and laptop PCs); Ubuntu Netbook Edition (for netbooks); and Ubuntu Server Edition (for use in servers).
