How feasting black holes time their burps
Black holes are voracious eaters, but they’re also quite messy, and often after devouring a star, they’ll let out a big burp, launching jets of high energy particles through space. Now, in a recent study, a team of astrophysicists has figured out the formula behind the timing of these burps. Also today: Skiing, hiking and roads are taking a toll on wolverinesThe buzzy, chirpy sounds of the Jurassic forestA notorious invasive species has been here a lot longer than we thought.

How corals tell us climate change is supersizing El Niño
The El Niño underway in the Pacific Ocean is a natural climate phenomenon but its warming effects are being boosted by climate change. Researchers recently used corals growing around the Galapagos Islands to create a local temperature record of the ocean going back 1,000 years.Also today: Massive study redraws bat family tree and uncovers genetic odditiesHow the Surinam toad uses star-shaped fingertip lobes to ‘see’ its preyT. rex tooth enamel reveals these dinosaurs were warm-bloodedWhy great white sharks are converging on the East Coast

Coral archives reveal a shift in El Niño strength
The El Niño underway in the Pacific Ocean has been called extraordinary, supersized and likely record-breaking. And while El Niño is a natural climate phenomenon, its warming effects are being boosted by climate change. Julia Cole, a paleoclimatologist at the University of Michigan, recently used corals growing around the Galapagos Islands to create a local temperature record of the ocean going back 1,000 years to add to what they've learned from similar studies elsewhere in the Pacific. She said the temperature record in this area of the East Pacific indicates that the El Niños from the last 40 to 50 years are unlike anything the area experienced in the last millennium. Her study was published in the journal Science.

Summertime and the science isn’t always easy
Summer is fieldwork time for many scientists. We talk to researchers who have been busy hiking on fresh lava, capturing thousands of ticks, shooing away moose from their study sites, and even spelunking for Neanderthals — all in the ever-important quest for data.
