An unexpected meeting helps solve an epidemiological mystery.
In the early 1980s, Aedes albopictus, a mosquito species native to Southeast Asia that spreads dengue fever and yellow fever, turned up deep in the American South. Though there were no reported disease outbreaks, epidemiologists were still worried, especially when huge swarms arrived in Houston. The so-called Asian tiger mosquito had clearly gained a foothold in the U.S., but no one knew how it had gotten there. So medical entomo ...read more
Cosmologists from the U.K., France and Germany have come up with new maps of how dark matter moves throughout the universe. Scientists can’t actually observe dark matter, which makes up about 27 percent of our universe’s total mass, since it doesn’t react to light. So these researchers had to infer its movement by using data from the Sloan Digital Sky Survey (SDSS), an ongoing project to create a 3-D map of the universe. Here, researchers have layered the location of galaxies ( ...read more

Is there anything more quintessentially American than a farmer in the heartland, toiling away on their land? But this vision of agrarian life will fade into the dusty shelves of sentimental nostalgia, because agriculture is poised to become an industry ruled by robot laborers. Companies like Hands Free Hectare (HFHa) are leading the way.
After a year of work, the HFHa project successfully harvested a crop of spring barley, grown ...read more

When aliens arrive in the movies, they typically come from distant galaxies. Extraterrestrial life, however, could exist right here in our own solar system, nestled in briny oceans under the surface of icy worlds close to home.
Multiple moons orbiting Jupiter and Saturn have proven to hold, or once held, liquid oceans. Of these, Saturn’s moon Enceladus has emerged as the most promising candidate for li ...read more
A new study shows that one million birds have been influenced by NYC’s annual “Tribute in Light,” which memorializes 9/11 victims. Scientists say the study shows the larger impact of light pollution. (Image by Abc36/Wikimedia Commons)
For one night every year, 88 Manhattan searchlights beam two columns of light toward the heavens. These “phantom towers,” known as the Tribute in Light, are an annual reminder of the thousands who died in the 2001 terrorist attacks.

On a warm, windy August day in 1981, a crowd gathered at the fairgrounds in Santa Rosa for the final event of the soybean fair that’s held every other year in the small city in southern Brazil.
Schools had let out so local students could attend, along with curious fairgoers and a collection of bigwigs whose rank rose all the way up to João Figueiredo, then the president of Brazil. Spee ...read more
