Sea ice in the Arctic has been melting at a record-breaking pace. Scientists blame a warming climate for most of that, but researchers have now teased out a natural cycle for how Arctic sea ice melts year-to-year.

Based on that cycle, they conclude that 30 percent to 50 percent of the melting is due to natural causes, while human-caused warming is responsible for the rest.

An orangutan named Rocky is helping scientists figure out when early humans might have uttered the first word.

Rocky, who is 12 and lives at the Indianapolis Zoo, has shown that he can control his vocal cords much the way people do. He can learn new vocal sounds and even match the pitch of sounds made by a person.

A few months ago, at her office in Houston, Kate Rubins was feeling weird.

She was dizzy, she says — "staggering around like a 2-year-old who had just learned to walk." She was constantly looking at her desk to make sure the objects on top weren't floating away.

Scientists have taken another important step toward creating different types of synthetic life in the laboratory.

An international research consortium reports Thursday that it has figured out an efficient method for synthesizing a substantial part of the genetic code of yeast.

"We are absolutely thrilled," says Jef Boeke, a geneticist at New York University School of Medicine, who is leading the project. "This is a significant step toward our goal."

The Republican health care overhaul working its way through the House is opposed by Democrats and by many Republican conservatives. It's none too popular with the people on the front lines of health care, either — including doctors, nurses and hospitals.

The chief medical officer of Medicaid, Dr. Andrey Ostrovsky, tweeted out his opposition on Wednesday. "Despite political messaging from others at HHS, I align with the experts ... in opposition to #AHCA," the career staffer said.

RadioShack has filed for bankruptcy for the second time.

Just over two years ago, the electronics chain declared bankruptcy and then reorganized its business, closing thousands of stores and selling others to a hedge fund called Standard General, which took over the remaining business through its affiliate General Wireless.

WikiLeaks will be sharing alleged CIA hacking techniques with major technology companies such as Apple and Google to allow them to develop fixes for vulnerabilities in their phones and other electronic devices, according to Julian Assange.
