Most of the diamonds synthesized from cremated remains come out blue, due to trace amounts of boron in the body. These diamonds, made from the ashes of animals, were created through the same process used to make diamonds from human remains.
Gov. Jerry Brown holds a chart showing California's average precipitation as he declares a drought state of emergency for the state Friday. Brown asked residents to voluntarily reduce water usage by 20 percent.
Saying that his state must take steps to plan for prolonged water shortages, Gov. Jerry Brown declared a state of emergency over an extended drought Friday. California faces "water shortfalls in the driest year in recorded state history," according to the governor's office.
The nation's capital is a pretty old city by American standards. It dates back to the late 18th century. Despite frequent face-lifts, parts of it are wearing out — for example, its underground gas pipelines. New research shows that Washington, D.C., suffers from thousands of leaks of natural gas.
"We drove 1,500 road miles in Washington, D.C., and found about 6,000 leaks," says Robert Jackson, an ecologist and environmental scientist at Duke University. "That's roughly four leaks every mile."
Kepler-22b, seen in this artist's rendering, is a planet a bit larger than Earth that orbits in the habitable zone of its star. Some researchers think there might be "superhabitable" worlds that may not resemble Earth.
In their hunt for potentially habitable planets around distant stars, scientists have been so focused on finding Earth-like planets that they're ignoring the possibility that other kinds of planets might be even friendlier to life, a new report says.
So-called superhabitable worlds wouldn't necessarily look like Earth but would nonetheless have conditions that are more suitable for life to emerge and evolve, according to the study published this month in the journal Astrobiology.
In desperation to save the rare northern spotted owl, biologists are doing something that goes against their core — shooting another owl that's rapidly taking over spotted owl territory across the northwest.
"If we don't do it, what we're essentially doing, in my view, is dooming the spotted owl to extinction," says Lowell Diller, senior biologist for Green Diamond, a timber company.

They were so young, the folks who invented America. James Madison, on July 4, 1776, was 25. James Monroe was 18, Alexander Hamilton, 21, Marquis de Lafayette, 18, Aaron Burr, 20, Betsy Ross, 24, Gilbert Stuart, 20. Ben Franklin, of course, was much older, grander and world famous. But he was the only one.
The world's biggest trees, such as this large Scots pine in Spain's Sierra de Baza range, are also the world's fastest-growing trees, according to an analysis of 403 tree species spanning six continents.

The General Sherman, a giant sequoia in California's Sequoia National Park, is more than 2,000 years old, and is thought to be the largest tree (by volume) in the world.
Like other animals and many living things, we humans grow when we're young and then stop growing once we mature. But trees, it turns out, are an exception to this general rule. In fact, scientists have discovered that trees grow faster the older they get.
Once trees reach a certain height, they do stop getting taller. So many foresters figured that tree growth — and girth — also slowed with age.
Florida may soon become the latest state to allow doctors to prescribe marijuana. Advocates there are gathering signatures to put a medical marijuana referendum on the fall ballot.
But Florida's Legislature may act sooner to allow residents access to a particular type of marijuana. Advocates say the strain called Charlotte's Web offers hope to children with severe seizure disorders.
The Freedom Industries facility sits on the banks of the Elk River last Friday, in Charleston, W.Va., site of a chemical spill that has led to a ban on using tap water in the area. The CDC says pregnant women in affected areas should drink only bottled water.
The Centers for Disease Control and Prevention is urging pregnant women who live in the areas of West Virginia where a toxic chemical leaked into the water supply last week to drink bottled water, even in places where the no-use ban has been lifted. The move comes "out of an abundance of caution," the CDC and the state's Bureau of Public Health say.
