Ransomware hit at least six countries Tuesday, including Ukraine, where it was blamed for a large and coordinated attack on key parts of the nation's infrastructure, from government agencies and electric grids to stores and banks.

The malware has been called "Petya" — but there is debate in the security community over whether the ransomware is new or a variant that has been enhanced to make it harder to stop.

States are not doing enough to improve safety on the roads, in the workplace and in the home, according to a new report from the National Safety Council.

The group, which graded all 50 states on safety, awarded no state an "A" grade for overall safety, but 11 states received an "F."

There's a big push in the U.S. from pediatricians to have mothers of newborns breast-feed exclusively for at least six months.

And many new moms want to. But only about 60 percent who start off breast-feeding keep it up for six months or more, according to the Centers for Disease Control and Prevention.

A federal judge in Michigan has temporarily barred U.S. Immigration and Customs Enforcement from deporting a group of more than 1,400 Iraqi nationals for at least two weeks, expanding an order that initially applied only to those in the Detroit area.

Note: This story contains a description of the alleged sexual assault at the center of the case.

A juror in the criminal trial of Bill Cosby says testimony from a second woman who said she was drugged and sexually assaulted by Cosby did not weigh heavily on the panel's 52 hours of deliberations. That statement comes in spite of prosecutors' hope that hearing from an additional accuser would have shown jurors that Cosby had a pattern of behavior.

Two-thousand miles away from the Supreme Court's vaulted ceiling and marble friezes, 60-year-old jobless mother Maria Guereca sat in her $20-a-month, one-room apartment with a fan and a hotplate — beside a picture of her dead son.

On Monday, the Court gave Guereca, who lives in Juarez, Mexico, a partial victory, saying a lower court erred in granting immunity to an agent who shot and killed her son.

The nonpartisan Congressional Budget Office weighed in on the Senate health care bill on Monday, saying that 22 million people would lose health coverage in the next 10 years under the Senate's plan. Of those, 15 million would lose Medicaid coverage. It's projected to lower the deficit by billions over 10 years, and also cut taxes on corporations and the wealthy.

The European Commission has fined Google 2.42 billion euros ($2.72 billion) after finding that the company used its dominant search engine to drive people toward another Google product, its shopping service.

"What Google has done is illegal under EU antitrust rules," said European Commissioner for Competition Margrethe Vestager. "It denied other companies the chance to compete on the merits and to innovate. And most importantly, it denied European consumers a genuine choice of services and the full benefits of innovation."

Medicaid is the government health care program for the poor.

That's the shorthand explanation. But Medicaid is so much more than that — which is why it has become the focal point of the battle in Washington to repeal and replace the Affordable Care Act, also known as Obamacare.
