How is this possible? Mysterious microbe is missing mitochondria

Imagine meeting another human who lacks a heart, lungs or some other crucial organ, and yet seems to be functioning completely normally. An international team of scientists has discovered the single-celled version of this conundrum: a eukaryotic microbe that has lost its mitochondrion, which scientists long thought was essential for these complex cellular organisms.

The microbe Monocercomonoides sp., described in the journal Current Biology, upends the long-held assumption that mitochondria are essential to eukaryotic cells as we know them. The findings also shed light on the evolutionary pressures that have made the partnership between cells and their mitochondria so profoundly successful – and reveal the situations when that relationship may fall apart.

The discovery showcases “an example of the amazing evolutionary plasticity of eukaryotic cells,” said first author Anna Karnkowska, a protistologist at the University of British Columbia in Vancouver who performed the research while she was a post-doctoral fellow at Charles University in Prague.

When the oil boom went bust, Oklahoma protected drillers and squeezed schools

By Luc Cohen and Joshua Schneyer

Filed May 17, 2016, 1:37 p.m. GMT
Oilmen won a big victory when legislators made permanent one of the juiciest tax breaks in the United States. Schools, meanwhile, are having to cut classes, administrators and teachers to make up a growing revenue shortfall.

NEWCASTLE, Oklahoma – After intense lobbying, Oklahoma’s oilmen scored a victory two years ago. State lawmakers voted to keep in place some of lowest taxes on oil and gas production in the United States - a break worth $470 million in fiscal year 2015 alone.

The state’s schools haven’t been so fortunate. In Newcastle, 23 miles from the capital of Oklahoma City, John Cerny recently learned that the school attended by his five-year-old granddaughter, Adelynn, will open just four days a week next year. The Bridge Creek school district will slash spending because of a projected $1.3 billion state budget shortfall next year.

Beth Lawton teaches first grade at Broadmoore Elementary in Moore, a city of 59,000 bordering the capital. In April, she and several colleagues were told their contracts won’t be renewed because of funding cuts. Broadmoore’s class sizes are expected to rise next year as a result.

“I think our lawmakers have failed us, and I don’t understand how little they value education,” Lawton said.

Meet Brazil’s new cabinet:science minister is a creationist

Simon Romero, The New York Times


BRASÍLIA, Brazil — The new Brazilian president’s first pick for science minister was a creationist. He chose a soybean tycoon who has deforested large tracts of the Amazon rain forest to be his agriculture minister. And he is the first leader in decades to have no women in his Cabinet.

The new government of President Michel Temer — the 75-year-old lawyer who took the helm of Brazil on Thursday after his predecessor, Dilma Rousseff, was suspended by the Senate to face an impeachment trial — could cause a significant shift to the political right in Latin America’s largest country.

“Temer’s government is starting out well,” Silas Malafaia, a television evangelist and author of best-selling books like “How to Defeat Satan’s Strategies,” wrote on Twitter.

“He’ll be able to sweep away the ideology of pathological leftists,” Malafaia added of a conservative lawmaker whom Temer chose as education minister.
