During the past few years, the biocompatibility of biomaterials (non-vital material intended to interact with biological systems within or on the human body) has evolved into a comprehensive, complex, and independent discipline of biomaterials science. Consequently, a number of terms have been developed or were adopted from toxicology. Some of these terms may be familiar to patients and clinici...

Before launching a missile, it is necessary to design an efficient safety net for self-protection. In this issue of Cell, Ellermeier et al. (2006) describe the mechanism underlying a biological safety net for the soil bacterium Bacillus subtilis. This bacterium protects itself from a toxic protein it secretes by upregulating an immunity protein, which it does by sequestering a transcriptional r...

For the past 50 years, quality control and safety tests have been used to evaluate vaccine safety. However, conventional animal safety tests need to be improved in several aspects. For example, the number of test animals used needs to be reduced and the test period shortened. It is, therefore, necessary to develop a new vaccine evaluation system. In this review, we show that gene expression pat...

Drivers tend to adapt their behavior to the increased safety margins created by the system by driving at higher speeds and paying less attention to driving. From a traffic safety perspective, it is therefore important that driver support systems can adapt their support to how drivers actually use the system. We propos...
