Soviet collapse cut down on meat — and carbon

Soviet citizens ate much more meat on average than the rest of the world — until prices soared and the rouble weakened following the collapse of the Soviet Union in 1991. From 1992 to 2011, emissions dropped as cattle and pig numbers halved. At the same time, carbon was sequestered in the estimated one-third of cropland that was abandoned. The outcome: a net reduction of 7.6 billion tonnes of greenhouse gases — a result that could be reversed, because meat farming in the region looks set to rise again.

Opioid epidemic drives spike in infections

The opioid crisis that is killing tens of thousands of people every year in the United States has created a surge in bacterial and viral infections. The outbreaks include spikes in new cases of HIV and hepatitis that threatens to undo decades of progress. Researchers are scrambling to gather the data needed to combat the problem, hindered by the stigma that prevents some opioid users from seeking early treatment. “This is like HIV all over again,” says infectious-disease physician Judith Feinberg.

Pre-teen scientist confirms hand dryers hurt

Many hand dryers are dangerously loud for children — and louder than the manufacturers claim. Thirteen-year-old Nora Keegan, who published the findings last month in Paediatrics & Child Health, launched her research as a primary-school science project. Keegan tested 44 different dryers in Calgary, Canada, and found that many exceed 100 dBA — the top limit allowed for children’s toys in Canada — when measured lower and closer to the dryer, where children would stand. Keegan has also invented a prototype air diverter that reduces the noise level for shorter users.

FEATURES & OPINION

Dams might push Amazon to a knife-edge

The Belo Monte complex — slated to be one of the world’s biggest generators of hydroelectric power — promises to bring renewable energy and economic growth to Brazil. It will also contribute to deforestation that threatens to destabilize the Amazon, with global repercussions. “If that tipping point is crossed, it’s irreversible,” says climate scientist Carlos Nobre. “It’s an ongoing dynamic process that will really lead to savanna-ization of 50, 60 percent of the Amazon.”

“I love being a professor”

“We seriously risk scaring away excellent researchers from academic careers because we do not help them to see the factors that keep us in academia,” writes microbiologist Patrick Schloss. While acknowledging the hurdles for women, minorities and first-generation graduate students (he is none of the above), Schloss offers the top 10 reasons why he loves being an academic.
