If you've ever tried to lose weight, you've probably gotten drawn into the argument over whether it's better to cut carbs or fat from your diet. A new study doesn't completely resolve that question, but it does provide an important insight.
Some proponents of the low-carb diet insist that you must cut carbs to burn off body fat. Their reasoning goes that when you cut carbs, your body's insulin levels drop, and that's essential in order to burn fat.
Learning to make sounds by listening to others is a skill that helps make us human.
But research now suggests a species of monkey may have evolved similar abilities.
Marmosets have the capacity to learn calls from their parents, according to research published Thursday in the journal Science. The results mean that studying marmosets might provide insights into developmental disorders found in humans. It also suggests that vocal learning may be more widespread than many researchers thought.
Christopher Clark, who directs the bioacoustics research program at Cornell University, is among the world's best scientific listeners. His work has revealed how human-made noise is filling the ocean, making it harder for marine animals to hear their own world. But Clark didn't start out with much interest in whales at all.
A few months ago, a 10-year-old gray-and-white cat called Bootsie was taken, together with his mother and brother, to an animal shelter in Virginia. The caretakers of the cats said they were just too old to care for animals anymore.
Bootsie's mother and brother were sent away to another animal shelter in the state. Bootsie, deemed "too shy" and thought to have a low chance of being adopted, ended up at the Animal Resource Foundation a few miles from my house, where the hope was that he might be socialized with some extra attention in a place quieter than the shelter.

NPR's Melissa Block talks with Kelly Beatty, senior contributing editor for Sky & Telescope, about the annual Perseid meteor shower, which reaches its peak Wednesday night. The event is a cascade of particles traveling at about 37 mph and appearing in the sky as purple streaks. They show up in August every year because Earth is in the path of the Comet Swift-Tuttle.
