In touch with molecules

A team of European researchers has achieved the first experiment to study the electrical behavior of only two C60 molecules touching each other. The investigation revealed that the conductance between the two molecules is significantly lower than expected, with a controlable leakage current between neighboring circuits.

Faithful mothers have healthier babies

A study of over 2500 pregnant women found that those in long-term relationships with their biological fathers were less likely to develop pre-eclampsia and have undersized babies. Prolonged exposure to paternal antigens may induce tolerance in the maternal immune system, reducing the risk of these conditions.
