Washington, March 29 : A breakthrough study by researchers at Brandeis University and the MRC Laboratory of Molecular Biology (Cambridge, U. K.) has for the first time provided significant insights into a crucial step in the process whereby human genetic information is transmitted to action in the human cell, and frequently at which point genetic disease develops in humans.

The researchers say that they have been successful in crystallizing a very large complex of a macromolecular "machine" in the human cell, in determining what it actually looks like, and thereby in zeroing in on the process of genetic encoding.

Washington, March 29 : Cumulative exposure to lead at levels likely to be experienced in community settings may have adverse consequences for women’s cognition in their later years, according to a study.

The study, supported by the National Institute of Environmental Health Sciences, was conducted with a view to examine biomarkers of lead exposure in relation to performance on cognitive tests given to older women.

Lead exposure is measured in two ways—blood lead level, which is a reading of recent lead dosage; and bone lead level, which is a cumulative measure of lead exposure over many years.

Washington, March 29 : Scientists at the University of Michigan have come up with a new method of detecting nitric oxide in exhaled breath, elevated levels of which are a telltale sign of diseases like lung cancer and tuberculosis.

The researchers say that their work may prove useful in diagnosing illness and monitoring the effects of treatment.

Chicago, March 29 : Michelle Obama has changed the way tickets are distributed for the yearly Easter Egg Roll at the White House by making them available online.

The U. S. First Lady reworked the conventional "first come, first served'''' process, which had previously seen many piling all night on the Ellipse before the roll, to make it more accessible for those from other towns.

Washington, Mar 29 : Drug-eluting stents are much safer and superior to bare metal stents in preventing death and heart attacks among cardiac patients, according to researchers from Duke University Medical Center.

For their study, the researchers tested drug-eluting stents among 262,700 "real-world" patients enrolled in a nationwide registry of cardiovascular disease.

The study is the largest of its kind to date, and may finally put an end to years of controversy over the safety of the devices.

Washington, Mar 29 : The United States fully supports the elected leadership of Pakistan and will work with them closely to ensure that the enhanced American assistance is used toward socio-economic uplift of the people as part of efforts to deal with violent extremism afflicting the country.

US official Bruce Riedel, chair and lead author of the panel that crafted the policy for the Obama Administration’s way forward in the Pakistan-Afghanistan region, called for proceeding cautiously on putting any overly-legislative or other restrictions on aid for Pakistan.
