Despite medicines for patients with vascular disease, a large international study shows these patients have a surprisingly high rate of recurring strokes, heart attacks and hospitalizations as well as mortality. Patients in North America experienced an above-average rate of these events. Patients in Eastern Europe had the highest rate, and those in Australia and Japan had the lowest.

(American Friends of Tel Aviv University) A new mathematical tool from Dr. Eran Halperin of TAU's Blavatnik School of Computer Science aims to protect genetic privacy while giving genomic data to researchers.

Biophysicists in Germany are leading an effort to develop and apply models of the so-called lateral-line system found in fish and some amphibians. This sensory organ enables an animal, even in murky water, to map its surroundings and recognize other animals. In a new study, the researchers report mathematical models that capture essential elements of the system, agree with experimental data, and could be easy to implement technically, as in robots.

Mothers and fathers play different roles and make different contributions to a child's upbringing, but a father's influence upon a child's academic success later in life is felt the most when he's involved from the very beginning, according to a new study.

Researchers have developed a new calibration technique that will improve the reliability and stability of the microhotplate -- a novel device being developed as the foundation for miniature yet highly accurate gas sensors that can detect chemical and biological agents, industrial leaks and even signs of extraterrestrial life from aboard a planetary probe.
