Critical step traced in anthrax infection
Scientists at Harvard Medical School (HMS) have revealed details of a key step in the entry of anthrax toxin into human cells. The work, which grew out of an ongoing effort to produce a better anthrax therapeutic, shows that the protective antigen component of the bacterial toxin plays an active role in transferring the other two components of the toxin through the cell membrane. The resea...Roots of polycystic ovarian syndrome traced to mother’s wom
How the daughters develop in their mother’s womb can be an indication of how they may be at risk// from developing polycystic ovarian syndrome. Polycystic ovarian syndrome is a condition that affects about 10% of the women in the childbearing age.

The reaction to a common water pollutant called arsenic may not be the same in all people. Researchers have // pointed out to a gene called CYT19 in people, particularly in children, that may be responsible for varied reactions to the metal called arsenic. Arsenic exposure had long been associated with health hazards like cancer of the skin, lungs or bladder, circulatory problems, and...Scientists Have Traced How The SARS Virus evolved
