Clean fuels could reduce deaths from ship smokestacks by 40,000 annually

Rising levels of smokestack emissions from oceangoing ships will cause an estimated 87,000 deaths worldwide each year by 2012 — almost one-third higher than previously believed, according to the second major study on that topic. The study says that government action to reduce sulfur emissions from shipping fuel (the source of air pollution linked to an increased risk of illness and death) could reduce that toll. The study is in the current issue of ACS' Environmental Science & Technology, a semi-monthly publication. more

Faster, more cost-effective DNA test for crime scenes, disease diagnosis

Scientists in Japan are reporting development of a faster, less expensive version of the fabled polymerase chain reaction (PCR) a DNA test widely used in criminal investigations, disease diagnosis, biological research and other applications. The new method could lead to expanded use of PCR in medicine, the criminal justice system and elsewhere, the researchers say. Their study is scheduled for the July 15 issue of Analytical Chemistry, a semi-monthly journal. more
