When this tree is down in the trenches of a dry season and battling pesky leaf-eaters, it calls upon its trusty allies: ants. Ecuador laurel trees will produce an extra dose of sweet, sticky sap to attract Azteca pittieri ants that aggressively protect their arboreal home from herbivores, says a new study in PLOS Biology. Trees and ants are often sturdy allies, said lead author Elizabeth Pringle, an ecologist at the University of Michigan in Ann Arbor. A complex food chain can take place among their branches: Little scale insects suck sugary sap out of the tree's innards and then poop it out as "honeydew.

What do you see in the ethereal photo above? An electric blue caterpillar? A wispy tadpole? How about a star struggling to be born? The image, captured by the Hubble Space Telescope, shows a star 4,500 light-years from Earth trying to form in the face of a powerful stellar wind. The glowing white head of the caterpillar shape is the core of the protostar. This is where the nuclear process has just begun, allowing the dense collection of gas, plasma and dust to shine with its own light, explains Zolt Levay of the Space Telescope Science Institute in Baltimore.

Heavy-equipment maker Caterpillar Inc. reported a 45% drop in first-quarter profit and cut its full-year outlook amid a slowdown in its mining business. The Peoria, Ill., company said mining companies continue to reduce their spending and new equipment orders remain weak after a surge last year. But Caterpillar said its sales in China increased in the quarter ended March 31, and that it's becoming more optimistic about the U.S. housing sector. "What's happening in our business and in the economy overall is a mixed picture," said Doug Oberhelman, Caterpillar's chairman and chief executive.

As quests go, the one Thousand Oaks garden designer David Snow embarked on is a doozy. For six months, Snow has devoted himself to saving the reputation of America's most beloved butterfly by getting the world's largest maker of pesticides to change its ways. Specifically, Snow wants Ortho to change the labels on its "Bug-B-Gon" and "Flower, Fruit and Vegetable Insect Killer" so they no longer feature images of the striking monarch butterfly caterpillar under the ominous vow, "guaranteed results.

Democratic efforts to frame recent Republican policies and right-wing statements as part of a larger “war on women” led by the GOP took another step Sunday. On CNN's “State of the Union,” Democratic National Committee Chairwoman Debbie Wasserman Schultz portrayed Republicans as “turning back the clock for women.” “Gov. [Scott] Walkerjust signed a bill that repeals the equal pay law that they had in Wisconsin for years,” she said to host Candy Crowley. “You have Republicans that have engaged themselves for the entire Congress on trying to redefine rape as only being forceful rape, defunding Planned Parenthood and family planning programs.” Wasserman Schultz's remarks, in which she also called the GOP "callous and insensitive," follow Republican National Chairman Reince Priebus' response Thursday to allegations of a war on women on Bloomberg TV. “If the Democrats said we had a war on caterpillars, and mainstream media outlets talked about the fact Republicans have a war on caterpillars, then we have problems with caterpillars,” Priebus said.
