Bursts of waves drive immune system 'soldiers' toward invaders
...ot directly observed, but is consistent with their observations and experiments. In the research, the team used the fluorescently tagged Hem-1 to determine whether the protein participated in the wave action, or was the wave itself. Using optical tricks to label specific pools of Hem-1, they found that molec...Study finds gender differences in renal and other genes contributing to blood pressure

The results reinforce previous observations of the role of gender in cardiovascular traits and imply that the development of genetic diagnostic and therapeutic indices for hypertension must take gender into account to provide an accurate assessment and treatment of hypertension. ...The 'female advantage' in kidney disease does not extend to diabetic women
... diabetic kidney disease. According to Maric, "Our observations suggest that kidney disease in diabetic women may not be the result of absolute levels of hormones, as previously thought, but to the relative ratio of [sex hormone] androgen to estrogen. It may well be that the ratio of the two hormones is what dete...New technology and global observations have improved resource-management decision making from disaster detection and mitigation of fires, insect outbreaks, storms, and floods, to agricultural management and basic ecological research, says Dennis Ojima (Colorado State University).

In particular, we have had no way to study how the seals interact with their environment and the prey wi...Role of thyroid hormones in slumber under investigation at Rutgers
