The ‘rock snot’ choking rivers may be native algae. Experts blame its sudden and dramatic emergence on changes in Earth’s atmosphere, soils and climate.
Fossils in nest of newfound pterosaur species suggest these animals were part of a social network — and may even have lived communally.

Flexible and unbreakable digital displays could soon be for sale, thanks to a new organic transistor made from plastic.
Biologists have started eavesdropping on bees — or their dancing sign language — to identify where these buzzers prefer to forage. This info is pointing to which bee-friendly habitats may be most important to preserve.
An environmentally friendly lighting technology promises not only to save energy but also to transform our indoor environment.
SCIENCEBefore reading:1. A 13-watt compact fluorescent light bulb provides the same amount of light as a traditional 60-watt incandescent light bulb. How much less energy does a compact fluorescent bulb use, expressed as a percentage?2. Turn on a lamp fitted with a traditional incandescent light bulb. Hold your hand over the bulb. (Be very careful not to touch the actual bulb.) What do you feel? Does that suggest that kind of bulb is efficient or wasteful?During reading:1. Detail some of the drawbacks to incandescent and fluorescent lighting.2. What does OLED stand for?3. Define solid-state.4. What is inside a fluorescent light?5. How hot does a tungsten filament glow?
Separated at birth: Astronomers find a star 110 light-years away. It was born at the same time as our sun and from the same cloud of gas and dust.
When koalas sprawl over a tree branch, they may not be lazy. They just might be taking advantage of some natural cooling — enough to survive a heat wave.
One hundred students from 30 states participated in the fourth annual White House Science Fair in Washington, D.C.
Scientists have developed an umbrella that ‘listens’ to falling raindrops. One day, a fleet of such simple rain gauges may help scientists better map weather patterns and changes in Earth’s water supplies.
On a planet far, far away, a single pass around its sun may seem to last forever.
Inspired research put select high school seniors on the path to the 2014 Intel Science Talent Search finals.
Here’s a scary cost to pumping up groundwater to slake the thirst of crops in California’s Central Valley: It may uplift nearby mountains and trigger tiny earthquakes, experts find.
An extract of local seeds in Puerto Rico may be the key to keeping mosquitoes away. It kills the larval insects and repels the biting adults.
The brain’s hippocampus helps store memories. It is smaller in college football players — especially if they have suffered concussions.
More than 3,000 world languages face extinction. Linguists are turning to mobile apps and other tech tools to preserve these endangered languages.
SCIENCEBefore readingWhat language or languages did your ancestors speak two, three or more generations ago? Do you or does anyone else in your family still speak that same language (or languages) today? Why or why not?Could you teach yourself a foreign language without ever directly communicating with a speaker of that language? How would you do so? What sorts of materials would you use?During readingWhat makes Matukar Panau so rare?Define what makes a language “endangered.”About how many languages worldwide could go extinct by the end of the 21st century?How does a language die?List some of the most commonly spoken world languages.What is a language hotspot?In what ways did the U.S. government discourage Native Americans from using their own languages?
Caffeine may be the trick to confusing some bacteria into thinking they’ve not yet summoned enough troops to launch a successful attack on their host. It could prove an alternative to antibiotics for certain infections.
