<p>In rural Ghana, stingless bees are well known as useful animals. Farmers raid natural hives to collect honey, which they use to treat ailments from eye infections to asthma. Many say the bees improve crop yields, and people refer to different species by their indigenous monikers. (The tifuie, for instance, is named after its tendency to get caught in people’s hair.) Despite farmers’ familiarity with these small bees, however, “they had no idea that they could bring them home and culture them and keep them,” says entomologist Peter Kwapong.</p>

<p>The temperature of a nest can affect a hatchling lizard&#8217;s size, speed, and sex. Now, the reptiles can add smarts to the list. Researchers have found that lizards incubated in warmer environments may learn faster than others. The results are preliminary, but they suggest that a hotter climate could give some lizards a cognitive edge, potentially helping them escape predators. </p>

January-February 2012 </p>
<p>When China opened its borders to international commerce in the late 1970s, it got more imports than it really wanted. Among the extras was the red turpentine beetle <em>(Dendroctonus valens)</em>, a wood-boring species native to North America. In its home range, <em>D. valens</em> is an unremarkable forest dweller that mainly colonizes dead and dying trees. But in China, it has wiped out more than seven million vigorous pines in the past dozen years, and it looks poised to spread through much of Eurasia. </p>

<p>There&#8217;s nothing subtle about dryer lint: Clean the fluffy, gray mat off the filter or risk a fire. Washer lint, however, is sneaky. Nearly 2000 polyester fibers can float away, unseen, from a single fleece sweater in one wash cycle, a new study reports. That synthetic lint likely makes its way through sewage treatment systems and into oceans around the world. The consequences of this widespread pollution are still hazy, but environmental scientists say the microscopic plastic fibers have the potential to harm marine life. </p>
