Buzz: The Nature and Necessity of BeesThor HansonBasic Books, $27
When you hear the word bee, the image that pops to mind is probably a honeybee. Maybe a bumblebee. But for conservation biologist Thor Hanson, author of the new book Buzz, the world is abuzz with thousands of kinds of bees, each as beautiful and intriguing as the flowers on which they land.
Speaking from his “...
This wasn’t 15-year-old Connor McMahon’s first time in the hospital. But the 107° fever he’d been running for three days had his dad frightened. The teen was hallucinating, talking gibberish and spouting curses.

Getting robots to do what we want would be a lot easier if they could read our minds.
That sci-fi dream might not be so far off. With a new robot control system, a human can stop a bot from making a mistake and get the machine back on track using brain waves and simple hand gestures. People who oversee robots in factories, homes or hospitals could use this setup, to be presented at the...
The story of how some of the massive stone statues on Rapa Nui, also known as Easter Island, ended up wearing stone hats involves ramps, ropes and remarkably few workers, a contested new analysis suggests.
No more than 15 people were needed to manipulate ropes that rolled stone cylinders, or pukao, up ramps to the top of forward-leaning statues, say archaeologist Sean Hixon of Penn State...

Starve the tumor, not the cell
Animal experiments demonstrate for the first time that transplanted tumors release a chemical into the host’s bloodstream that causes the host to produce blood vessels to supply the tumor.… If such a factor can be identified in human cancers … it might be possible to prevent the vascularization of tumors. Since tumors above a certain small size require...
If you’re a female computer scientist, you may not see an equal number of men and women working in your field in this century — or even the next one. It might take a whopping 280 years for that scientific discipline to bridge the gender gap, researchers report online April 19 in PLOS Biology.
The study predicts when the gender gap will close in science, technology, engineering, math and...
