Washington, Mar 19 : A new study has revealed that black girls are 50 percent more likely than white girls to suffer from the eating disorder bulimia.

The findings of the study led by researchers from University of Southern California, University of Maryland and Universitat de Autonoma Barcelona, Spain, challenge the widespread perception that bulimia primarily affects the privileged.

Asian-African girls, in particular, were found to be suffering the eating disorder.

Washington, Mar 19 : Two of the most commonly prescribed anti-seizure medications may increase the risk of cardiovascular problems, such as high cholesterol levels and C-reactive protein, according to a study.

The discovery of this repercussion in the treatment of epilepsy may help doctors offer better care of patients with seizures by prescribing different anti-seizure medications that do not harm cardiovascular health.

Washington, March 19 : The panoramic camera on NASA’s Mars rover Opportunity has caught a first glimpse on the horizon of the uplifted rim of the big crater that has been Opportunity’s long-term destination for six months.

Opportunity’s twin, Spirit, also has a challenging destination, and last week switched to a different route for making progress.

Washington, March 19 : Scientists at The University of Nottingham have found that a biological pathway plays a role in the development of a type of brain tumour that predominantly occurs in children, and presently has a very poor prognosis.

Working on behalf of the Children's Cancer and Leukaemia Group (CCLG), the researchers have found that the WNT biological pathway is "activated" in over one-third of the cases of central nervous system primitive neuroectodermal tumours (CNS PNET).

Washington, March 19 : With the aid of a new method developed by scientists in Germany, the output frequency of the atomic fountains clocks has become more stable.

At present, Caesium fountain clocks are the most accurate clocks in the world, furnishing the second accurate to 15 places after the decimal point.

Until they reach this accuracy, caesium fountain clocks, however, need a certain measurement time.

This time has now been considerably reduced with the aid of a new method developed at the Physikalisch-Technische Bundesanstalt (PTB), which makes the output frequency of the caesium fountains more stable.

For excitation of the caesium atoms, the PTB physicists make use of a novel microwave source.
