Honeybees can be managed in hives because in nature they congregate in tree cavities, but 70 percent of wild bees nest in the ground, often as solitary insects or as a congregation of loners: Think of an apartment building full of singles. Maybe as many as a third of bees evolved to feed off a given flower or flower family. The others are generalists and will devour whatever nectar and pollen is around. – Adrian Higgins

How will those trees evolve over time with their altered genome? Will they crowd out the remaining natural chestnuts? The consequences of genetic engineering can be unpredictable — genes behave and are expressed in complex ways.

This image obtained in 2002 from NASA shows one of the twin Voyager spacecraft, launched in 1977.
On Thursday, scientists declared that it had become the first probe to exit the solar system, a breathtaking achievement that NASA could only fantasize about back when Voyager was launched in 1977, the same year “Star Wars” was released.

Pictured above, the Sakurajima volcano in southern Japan was caught erupting in early January. Magma bubbles so hot they glow shoot away as liquid rock bursts through the Earth’s surface from below. The above image is particularly notable, however, for the lightning bolts caught near the volcano’s summit. Why lightning occurs even in common thunderstorms remains a topic of research, and the cause of volcanic lightning is even less clear. Surely, lightning bolts help quench areas of opposite but separated electric charges. One hypothesis holds that catapulting magma bubbles or volcanic ash are themselves electrically charged, and by their motion create these separated areas. Other volcanic lightning episodes may be facilitated by charge-inducing collisions in volcanic dust. Lightning is usually occurring somewhere on Earth, typically over 40 times each second.
