It's becoming routine for cancer doctors to order a detailed genetic test of a patient's tumor to help guide treatment, but often those results are ambiguous. Researchers writing in Science Translational Medicine Wednesday say there's a way to make these expensive tests more useful.

Here's the issue: These genomic tests scan hundreds or even thousands of genes looking for mutations that cause or promote cancer growth. In the process, they uncover many mutations that scientists simply don't know how to interpret — some may be harmless.

The night before he disappeared, Dennis Lee Thian Poh called his wife in Kuala Lumpur. They chatted about the bitter cold in Nepal's Annapurna range and he said that dinner in his small lodge had consisted, yet again, of vegetable fried rice.

Lee, 47, had been hiking for six days in Nepal's most visited trekking zone, the Annapurna Conservation Area.

The U.S. Capitol Police have confirmed that Douglas Mark Hughes of Ruskin, Fla. was the pilot who landed a gyrocopter not far from the capitol building.

Police searched the vehicle, saying "nothing hazardous" was found. The gyrocopter was relocated to a secure location, the department said in a statement.

Shortly after landing, Hughes was quickly named by friends and news outlets as the man who flew low over the reflecting pool to land near the Congressional buildings. He was met by police with their guns drawn.

"The exhibition of profound grief was such as I have never seen equalled. Several overcome by their emotion, sat down upon the very ground and wept."

That was how Thomas Nelson, a U.S. minister to Chile, described the reaction of ordinary citizens in Spain to the news of President Abraham Lincoln's assassination in 1865.

The U.S. will reach a new balance in energy trade "sometime between 2020 and 2030," says the Energy Information Administration, which predicts the U.S. could become a net energy exporter in the near future.

The federal agency's prediction cites a rise in domestic natural gas production and changes in energy demands. If it happens, the shift would end a streak of more than 50 years in which the U.S. has been a net importer of energy.

The White House announced Tuesday that President Obama would remove Cuba from the U.S. list of state sponsors of terrorism. That got us thinking about which other nations are on the list, how they got there, whether any others have been removed, and what happens to countries when they're put on (or taken off) the list.

Who's On The List?

Aside from Cuba, there are three other countries currently on the list:

The Pentagon says it will exhume the remains of 388 sailors and Marines who died on Dec. 7, 1941, in the capsizing of the USS Oklahoma during the Japanese bombing of Pearl Harbor.

Most children with autism get diagnosed around age 5, when they start school. But signs of the developmental disorder may be seen as early as 1 year old.

Yet even if a parent notices problems making eye contact or other early signs of autism, some doctors still dismiss those concerns, a study finds, saying the child will "grow out of it." That can delay diagnosis and a child's access to therapy.

Building a giant steel bale feeder is hard. Try it.

Problem No. 1: Unless you live in ranch country, you probably don't even know what it's supposed to look like — regardless of whether you can build one.

Problem No. 3: Getting it right requires some serious math.

Aaron Hernandez, whose rise to elite status in the NFL was ended by charges that he shot and killed a man, has been found guilty of first-degree murder. In 2013, Hernandez was accused of killing the boyfriend of his fiancee's sister.

The verdict comes on the seventh day of a jury's deliberations on counts that ranged from murder to gun and ammunition charges. As the findings were read in a Fall River, Mass., courtroom, Hernandez sat between his lawyers and occasionally shook his head.

Dana Lam was insured under her parent's health plan until the end of 2014, thanks to a provision of the Affordable Care Act that allows young adults to stay on family health insurance until they turn 26.

The arrangement worked out well until she needed treatment for depression. Lam knew that if she used her parents' health plan to see a psychotherapist or psychiatrist, her visit would show up on their insurance statements.

She wasn't ready to talk to them about her mental health issues. "I was just so afraid of having that conversation with them," she says.

Here's a question for you last-minute tax filers. See that little checkoff box at the top of the 1040 tax form, the one labeled "Presidential Election Campaign"? You didn't check it, did you?

If not, then you're just like pretty much everybody else.

Saying that Google has abused its dominant position in the search market "by systematically favoring its own comparison shopping product," the European Commission has sent a list of antitrust charges to the search giant. The European Union has also opened a new inquiry into the Android mobile system.

"I am concerned that the company has given an unfair advantage to its own comparison shopping service" and broken European law, says the EU commissioner in charge of competition policy, Margrethe Vestager.
