German intelligence officer has reportedly been arrested over a suspected Islamist plot to bomb the agency’s headquarters in Cologne.

The 51-year-old official was said to have made a “partial confession” to the plot, according to Der Spiegel.

The suspect attempted to pass on “sensitive information about the BfV (Germany’s domestic security agency), which could lead to a threat to the office”, an official told the newspaper.

“He is accused of making Islamist remarks online under a false name, and offering internal information during chats,” a BfV spokeswoman told AFP.

The suspect has, since April, been engaged in gathering intelligence on the Islamist scene in Germany, Der Spiegel said.

A Topeka man who answered a Craigslist ad to donate sperm so two women could have a baby together is not legally the child's father and isn't required to provide financial support, a Kansas judge has ruled.

The state Department for Children and Families had not decided as of Tuesday whether it would appeal last week's ruling by Shawnee County District Judge Mary Mattivi. The department sought to force William Marotta to pay child support for the girl born in December 2009.

Mattivi last year required Marotta to submit a DNA sample to confirm that he was the girl's biological father and declared he was not "a mere donor of sperm." But the judge's Nov. 22 ruling concluded that birth mother's former partner should be considered the child's second parent rather than Marotta, in part because he has had minimal contact with the girl.

California is taking its fight against global warming to the farm.

The nation's leading agricultural state is now targeting greenhouse gases produced by dairy cows and other livestock.

Despite strong opposition from farmers, Gov. Jerry Brown signed legislation in September that for the first time regulates heat-trapping gases from livestock operations and landfills.

Cattle and other farm animals are major sources of methane, a greenhouse gas many times more potent than carbon dioxide as a heat-trapping gas. Methane is released when they belch, pass gas and make manure.

"If we can reduce emissions of methane, we can really help to slow global warming," said Ryan McCarthy, a science adviser for the California Air Resources Board, which is drawing up rules to implement the new law.

Livestock are responsible for 14.5 percent of human-induced greenhouse gas emissions, with beef and dairy production accounting for the bulk of it, according to a 2013 United Nations report.

Since the passage of its landmark global warming law in 2006, California has been reducing carbon emissions from cars, trucks, homes and factories, while boosting production of renewable energy.

In the nation's largest milk-producing state, the new law aims to reduce methane emissions from dairies and livestock operations to 40 percent below 2013 levels by 2030, McCarthy said. State officials are developing the regulations, which take effect in 2024.

"We expect that this package ... and everything we're doing on climate, does show an effective model forward for others," McCarthy said.

• Although liberal families' incomes average 6 percent higher than those of conservative families, conservative-headed households give, on average, 30 percent more to charity than the average liberal-headed household ($1,600 per year vs. $1,227).
• People who reject the idea that “government has a responsibility to reduce income inequality” give an average of four times more than people who accept that proposition.
• Conservatives also donate more time and give more blood.
