Niger's own soldiers tried to take the palace, and Russian troops stopped them

World

The truth: A government that seized power promising to beat an insurgency was saved from its own soldiers by a foreign force, and what the soldiers were angry about was that the insurgency is being lost.

Finance

The truth: No government was punished this week for anything it did.

Tech

The truth: Nobody attacked a heart device.

Mind & body

The truth: One theory produced two treatments and only one of them worked - feeding babies the food cut allergy sharply, while greasing the skin from birth barely shifted eczema and did not prevent allergy at all.

Climate

The truth: Solar made electricity cheap at one time of day and left it dear at every other, and the record being set is not in making power but in moving it a few hours.

Space

The truth: A sovereignty programme has bought its first hardware from a German firm, while the operator trusted to run it built that trust on American-made satellites and has just ordered more of them.

Biotech

The truth: A national count of measles deaths is only the sum of what states report, so a federal review of one of them has nothing new to look at and can only add it or leave it out.

Money

The truth: Almost every fight over who gets what is a fight over a leftover pile, because the largest accounts were routed years earlier by a form nobody remembers signing.

Sports

The truth: A court settlement made US colleges start paying their players, and the sponsor logos arriving on courts and shirts this month are where that money is being found.

Gaming

The truth: A studio that spent every pound it had making a good game stopped paying the people who made it in the weeks before anyone could buy it, and the praise went out on schedule anyway.

Food

The truth: A claim everybody in the coffee trade wanted to be true was carried for a decade on studies that could not have shown it, because the farms they measured were having water pumped onto them.

Cyber

The truth: The July story was one program going wrong, which is a story with an ending.
