Given that vaccine supplies are often limited, a quantitative understanding of how the number and frequency of vaccinations can affect the growth rate of disease would be useful. Physicists show that even a small number of randomly vaccinated individuals can exponentially increase the extinction rate of a disease.

Molecular dynamics simulations show that thermal gradients – of order 10¹⁰ K over a meter - can polarize liquid water. The finding could have interesting implications for developing hyperthermal treatments that target cancer cells.
