Researchers have found they can boost levels of nutritious, cancer-fighting compounds in vegetables such as cabbage by fooling the vegetables into thinking it's a certain time of day.

Janet Braam, a biologist at Rice University in Houston, Texas, and her colleagues discovered in 2012 that Arabidopsis thaliana, a plant related to cabbages and broccoli, uses its internal biological clock or "circadian rhythm" to ramp up production of insect-fighting chemicals at the times of day when the insects are most likely to attack and feed on them.

...

Plants keep their internal clocks synchronized to the environment by detecting the light and temperature conditions around them.

...

Braam said the study was inspired by a conversation with her teenage son, after she told him about her earlier discovery of the link between the time of day and a plant's production of anti-insect chemicals. He commented that he now knew what time of day to eat his vegetables.

So yeah, this is pretty cool. Though as one comment put it...

Now we need to trick people into actually eating vegetables.

It doesn't concern you, Sister, that kind of absolutist view of the universe? Right and wrong determined solely by a single all-knowing, all powerful being whose judgment cannot be questioned and in whose name the most horrendous acts can be sanctioned without appeal?

Being required by someone else’s religious beliefs to behave contrary to one’s sexual identity is degrading and disrespectful.
