Washington, Mar 23: Heart disease is not only a product of genetic factors or lifestyle choices, air pollution also puts people at an increased heart attack risk, suggests a study led by Aruni Bhatnagar of the University of Louisville.

Evidence has shown that increase in particulate air pollution is also associated with an increase in heart attacks and deaths.

During the study, Bhatnagar found that risk of heart attack increases in parallel with time spent in traffic.

London, Mar. 23 : The Royal Navy elite flying instructors inspired the American Top Gun fighter pilot academy, a new book has revealed.

The British contribution of a dozen instructors was a substantial help to the Americans struggling for aerial success over Vietnam

Washington, March 23 : A new research has indicated that a ghostly property of matter, called quantum tunneling, may aid the quest for accurate, low-cost DNA sequencing and sensor applications.

Stuart Lindsay and his collaborators at the Biodesign Institute of Arizona State University have done the research.

Tunneling implies that a particle, say an electron, can cross a barrier, when, according to classical physics, it does not have enough energy to do so.

Unraveling the DNA sequences of the human genome a decade ago was a remarkable achievement.

Washington, Mar 23 : In a major advance in cancer treatment, nanotechnology researchers have developed the first hollow gold nanospheres that search out and "cook" cancer cells.

The researchers say that the cancer-destroying nanospheres, smaller than the finest flecks of dust, particularly show promise as a minimally invasive future treatment for malignant melanoma, the most serious form of skin cancer.

Kabul, Mar. 23 : United States Special Forces reportedly killed five people near the Afghan-Tajik border on Sunday, and claimed that they were militants.
