NATURE BRIEFING

Daily briefing: Black and Hispanic Americans breathe more than their fair share of deadly air pollution

White people make pollution, others breathe it in. Plus: nearly half of childhood cancer goes undiagnosed and 2D semiconductors could extend Moore’s law.

Nearly half of kids’ cancer cases go undiagnosed

Almost 400,000 children are thought to have developed cancer in 2015 — but 43% of those cases went undiagnosed. Figures estimated from World Health Organization data on who has access to health care are much higher than those from official cancer registries. “Because a lot of children don’t have access to primary care, they don't have access to cancer specialists — they don’t end up getting diagnosed,” says health-policy researcher Zachary Ward.

Seven nations form SKA supergroup

A CERN-like organization will manage the construction and operation of the world’s largest radio telescope, the Square Kilometre Array (SKA). Seven nations have agreed to establish an intergovernmental organization, called the SKA Observatory, to oversee the building plan. The array will ultimately comprise thousands of radio dishes in Africa and up to one million antennas in Australia..

White people make pollution, others breathe it

In the United States, black and Hispanic people bear many more of the deadly effects of air pollution, while creating less pollution themselves. Non-Hispanic white people are exposed to around 17% less air-pollution exposure than they make. African Americans bear a ‘pollution burden’ of 56% excess exposure, and Hispanic Americans face 63%. “The thing that’s causing the disparity is the different amounts of consumption,” says environmental engineer Christopher Tessum. “White people spend more money.”

How 2D semiconductors could extend Moore’s law

Incredibly thin transistors could deliver even more powerful computers if three research challenges can be solved, argue semiconductor researcher Ming-Yang Li and colleagues. We need the right materials, suitable test samples and a common assessment framework to make it happen, they say.

A source of light in the Middle East

Biophysicist Zehra Sayers and four colleagues won a science-diplomacy award for her role in setting up the Turkey’s first synchrotron light source. She tells Nature why having its own light source is important in the Middle East, and how she made it happen despite some rocky times in the region.

QUOTE OF THE DAY

“This is an extreme, unsubtle and illegal example of the increasingly common practice of using money to get an edge in the race for a place in an elite university.”

Christopher Hunt, who runs a consulting service for university applicants, responds to the news that 50 people have been charged with a bribery scheme to get rich offspring into top US universities. (The New York Times)
