The Australian captain Ricky Ponting has said that the team is only thinking of winning the Ashes on home soil. Last year, England has registered an empathic Ashes series win over the Australian team. That was second time in Ponting's career that Australia has encountered an Ashes series defeat.

In 2006-07 season, Australia has posted a 5-0 whitewash of the Ashes series. Now the Australia skipper is anticipating repeating the same in this season.

But this time it has become a tough task for him. Because the English team is quite confident and much composed.

It has been reported that scientists at the Max Planck Institute in Germany have moved closer to developing a pill that may help cure jet lag by resetting the body clock.

Jet lag is caused when the various natural timers in the body are "desynchronised" and knocked off balance by traveling long distances.

According to the reports, its failure to adjust to a new time zone leads to insomnia, loss of appetite, loss of alertness and even depression.

A rare side effect of standard treatments for the disease, scientists have explained Parkinson's patients'' risky behavior.

The finding, according to researchers, has implications for future medication of patients.

The treatments, which work by increasing dopamine signaling in the brain, can trigger highly risky behaviors, known as ''impulsive-compulsive spectrum behaviors'' (ICBs) in approximately 5-10 percent of patients.

According to media reports, Stem cells helped scientists restore the vision of 82 people with eyes blinded by chemical or heat burns.

Graziella Pellegrini at the University of Modena in Italy, according to New Scientist, has reported that of the 107 eye patients treated, some as long as a decade ago, the successful cases had sight restored to a level up to 0.9 on a visual acuity scale, in which 1 represents perfect vision.

For patients who had burns only in one eye, researchers treated them with corneal stem cells extracted from their good eye.

A new type of touch screen has been reported that could be less expensive and more durable.

Researchers in South Korea and Japan have claimed that they can make large pieces of graphene films, up to 30 inches long, for touch screen phones and flat panel TVs.

Discovery News has reported that most touch screens in phones are now made with indium tin oxides (ITO).

It has been reported that the ITO's greatest asset is that it's transparent, but it comes with a cost, ITO is exceedingly expensive, because it's made of rare materials.

According to the reports, scientists have unraveled the neural mechanisms in the brain that are linked with "courage."

The study provides fascinating insight into what happens in the brain when an individual voluntarily performs an action opposite to that promoted by ongoing fear.

The results, in fact, may even lead to new treatment strategies for those who exhibit a failure to overcome their fear.
