A humpback whale died at the Fauntleroy Ferry Dock in West Seattle Sunday, but officials aren't sure why.

The 39-foot juvenile female was stranded when the tide went out. Marine mammal experts said she was clearly in distress.

Scientists have answered a burning question central to the charm of sunflowers: Why do young flowers move their blooms to always face the sun over the course of a day?

And then: Once sunflowers reach maturity, why do they stop tracking the sun and only face east?

The federal government announced plans Thursday to lift a moratorium on funding of certain controversial experiments that use human stem cells to create animal embryos that are partly human.

The National Institutes of Health is proposing a new policy to permit scientists to get federal money to make embryos, known as chimeras, under certain carefully monitored conditions.

It's a warm, sunny morning at the Homestead National Monument of America in southeastern Nebraska. A burn crew dressed in yellow and green flame-resistant clothing is about to set a patch of tall-grass prairie on fire — on purpose.

Maybe it was a meteor? Or space junk? People on the West Coast weren't sure what the bright object was that streaked across the sky Wednesday night, but they knew it was spectacular. Now comes word that the object — which separated into bright fragments — was a stage of China's large new rocket.

For decades, Japanese fishermen have told stories about the existence of a dark, rare beaked whale that they called karasu — the "raven."

But now, scientists say they have genetic proof to back up these tales. Long mistaken for its relative, the Baird's beaked whale, scientists say it represents an entirely new species.

Kim Malcolm talks with ESPN's Steve Fainaru about allegations made against Dr. Richard Ellenbogen, chair of the Department of Neurological Surgery at the University of Washington. In May, a Congressional report alleged that Ellenbogen attempted to influence a federal study on football and brain disease. 

The trip had mechanical setbacks, and the plane's average speed would be legal on many American streets. But when the Solar Impulse aircraft touched down in Abu Dhabi in the early morning darkness Tuesday, it successfully completed a round-the-world voyage using only solar power.

Swiss pilots Bertrand Piccard and André Borschberg took turns flying the single-seat aircraft that began its trip on March 9 of 2015, flying more than 26,700 miles in a total of 17 stages (23 days) as they soared under the sun's power and then glided through the night.

More than 2 tons of supplies and gear are speeding toward the International Space Station, after a SpaceX Falcon rocket launched early Monday from Cape Canaveral, Fla. The cargo includes a new port that will standardize how spacecraft connect to the station.

Seabirds have been washing up dead on beaches in Washington and British Columbia this summer, and scientists can't say why.

Adult stem cells may skirt the pesky theological issues raised by embryonic stem cell research, but their unregulated marketplace is raising ethical issues of its own.

A study released at the end of last month found hundreds of clinics across the country that are marketing “unapproved” stem-cell therapies directly to patients.


Neanderthal Dinner: Reindeer With A Side Of Cannibalism

Jul 14, 2016

They were Neanderthals living roughly 40,000 years ago in a cave in Goyet, Belgium — and they were eaten by their own kind. That's the finding of a recent study published in Scientific Reports. The authors report that Neanderthal bones found in this cave show signs of being butchered, cracked to extract marrow, then used to shape tools.

These are undeniable signs of cannibalism, says anthropologist and study author Hélène Rougier of California State University, Northridge.

Letting mice watch Orson Welles movies may help scientists explain human consciousness.

At least that's one premise of the Allen Brain Observatory, which launched Wednesday and lets anyone with an Internet connection study a mouse brain as it responds to visual information.

Bill Radke speaks with Luke Timmerman about what went wrong during Seattle-based Juno Therapeutics' clinical trial of an immunotherapy treatment for leukemia and what it might mean for the company.

Will DNA molecules replace DVDs and flash drives?

In a  lab test tube at the University of Washington, scientists stored an HD video of the song “This Too Shall Pass” by OK Go on DNA molecules. They also stored the text of 100 books and the Declaration of Human Rights in multiple languages.

Now, they've broken their own record for the amount of media rich data they've encoded onto DNA.
