A California bill that would have required manufacturers to figure out how to keep the most common plastic junk out of state waterways died in the state Assembly without a vote Friday.
Assembly Bill 521 was before the chamber's Appropriations Committee, and the panel failed to act on it, effectively killing the legislation for the session. It had previously passed the Assembly Natural Resource Committee.

Moon being pushed away from Earth faster than ever
Earth is pushing the moon away faster now than it has for most of the past 50 million years, mostly a result of tides, a U.S. researcher says.
Matthew Huber of Purdue University says his models of the influence of tides on the moon's orbit help solve a longstanding mystery concerning the moon's age, NewScientists.com reported Wednesday.
Climate research nearly unanimous on human causes, survey finds
A survey of thousands of peer-reviewed papers in scientific journals has found 97.1% agreed that climate change is caused by human activity.
Authors of the survey, published on Thursday in the journal Environmental Research Letters, said the finding of near unanimity provided a powerful rebuttal to climate contrarians who insist the science of climate change remains unsettled.
Scientists successfully create human stem cells through cloning
After more than 15 years of failures by scientists around the world and one outright fraud, biologists have finally created human stem cells by the same technique that produced Dolly the cloned sheep in 1996: They transplanted genetic material from an adult cell into an egg whose own DNA had been removed.
The result is a harvest of human embryonic stem cells, the seemingly magic cells capable of morphing into any of the 200-plus kinds that make up a person.
Experimental aircraft speeds to more than 3,000 mph in test flight
A lightning-quick experimental aircraft made history when it sped more than 3,000 mph above the Pacific Ocean in a test flight, reigniting decades-long efforts to develop a vehicle that could travel faster than a speeding bullet.
The unmanned X-51A WaveRider, which resembles a shark-nosed missile, was launched midair Wednesday off the coast near Point Mugu. It sped westward for 240 seconds, reaching Mach 5.1, or more than five times the speed of sound, before plunging into the ocean as planned.
They're back: 17-year cicadas to swarm from Georgia to New York
Colossal numbers of cicadas, unhurriedly growing underground since 1996, are about to emerge along much of the U.S. East Coast to begin passionately singing and mating as their remarkable life cycle restarts.
This year heralds the springtime emergence of billions of so-called 17-year periodical cicadas, with their distinctive black bodies, buggy red eyes, and orange-veined wings, along a roughly 900-mile stretch from northern Georgia to upstate New York.
Solar-powered plane embarks on day-and-night journey across US
The ultralight plane, named Solar Impulse, took off from San Francisco on Friday morning.
It will take pilot Bertrand Piccard 19 hours to reach Phoenix, the first stop as his Solar Impulse aircraft hops across America, with stops in Dallas, St Louis, Washington DC and New York.
