      &lt;p&gt;&lt;strong&gt;Plant ecologists study circadian rhythms&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Circadian rhythms explain numerous biological processes in both animals and plants that arise in 24-hour cycles. Adding to this list, environmental scientists at Lancaster University report that circadian rhythms also influence the rate at which plants emit isoprene, an important chemical that reacts with nitrogen in the atmosphere to form one of the leading sources of ground-level ozone. The researchers also show that incorporating these body clock-influenced isoprene emission rates into atmospheric computer models improves ozone predictions. &lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Children act like scientists when they play&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Four-year-olds use science, according to recent MIT research. In the experiments, children were shown how to activate a toy in one of two ways: Activating the toy by connecting its various parts was demonstrated in a straightforward way to some children, while the demonstration was ambiguous for other children. ...&lt;/p&gt;
