Impulsive boys with inadequate supervision, poor families and deviant friends are more likely to commit criminal acts that land them in juvenile court, according to a new study. The most surprising finding from the 20-year study was how help provided by the juvenile justice system substantially increased the risk of the boys engaging in criminal [...]

Expectant mothers who are obese are much more likely to suffer from minor complications such as heart burn and chest infections during pregnancy, a study suggests. Research found that obese mothers-to-be were nearly 10 times more likely to suffer from chest infections, and more than twice as likely to suffer from headaches and heartburn, compared [...]

Secure Internet activity requires being able to prove who you are, and experts agree that the traditional approach of passwords is not always effective. PKI and public key cryptography solve these problems, and a new system is now in the pipeline with the Internet Engineering Task Force to become the universal way to easily implement [...]

Neural stem cells represent the cellular backup of our brain. These cells are capable of self-renewal to form new stem cells or differentiate into neurons, astrocytes or oligodendrocytes. The receptors of the Notch family play a significant role in this process. So far, only stimulating extracellular ligands of Notch receptors had been described. Biochemists now [...]
