Gut bacteria could be responsible for side effect of Parkinson's drug

Bacteria in the small intestine can deaminate levodopa, the main drug that is used to treat Parkinson's disease. Bacterial processing of the unabsorbed fractions of the drug results in a metabolite that reduces gut motility. These findings were described in the journal BMC Biology on 20 October by scientists from the University of Groningen. Since the disease is already associated with constipation, processing of the drug by gut bacteria may worsen gastrointestinal complications.

History shows that societies collapse when leaders undermine social contracts

All good things must come to an end. Whether societies are ruled by ruthless dictators or more well-meaning representatives, they fall apart in time, with different degrees of severity. In a new paper, anthropologists examined a broad, global sample of 30 pre-modern societies. They found that when "good" governments—ones that provided goods and services for their people and did not starkly concentrate wealth and power—fell apart, they broke down more intensely than collapsing despotic regimes. And the researchers found a common thread in the collapse of good governments: leaders who undermined and broke from upholding core societal principles, morals, and ideals.

Does science have a plastic problem? Microbiologists take steps to reducing plastic waste

Led by Dr. Amy Pickering and Dr. Joana Alves, the lab replaced single-use plastics with re-useable equipment. Where alternatives were not available, the group decontaminated and re-used plastic equipment which would have usually been thrown away after one use. "We knew that we were using plastic daily in our research, but it wasn't until we took the time to quantify the waste that the volumes being used really hit home. That really emphasized the need for us to introduce plastic reducing measures," said Dr. Pickering.

Thinning and prescribed fire treatments reduce tree mortality

To date in 2020, 1,217 wildfires have burned 1,473,522 million acres of National Forest System lands in California; 8,486 wildfires have burned over 4 million acres across all jurisdictions in California. This current fire activity comes after forests in the region experienced an extreme drought accompanied by warmer than normal temperatures from 2012 to 2015, resulting in the deaths of over 147 million trees, mostly from bark beetles. These dead trees are now adding more fuel to this summer's wildfires, especially in the southern and central Sierra Nevada, where tree mortality was the heaviest.
