Highly selective membranes: Researchers discover how water can affect its own filtration

Membranes with microscopic pores are useful for water filtration. The effect of pore size on water filtration is well-understood, as is the role of ions, charged atoms that interact with the membrane. For the first time, researchers have successfully described the impact water molecules have on other water molecules and on ions as part of the filtration mechanism. The researchers detail a feedback system between water molecules that opens up new design possibilities for highly selective membranes. Applications could include virus filters.

Results from the DEFINE-FLOW study reported

A new observational study of deferred lesions following combined fractional flow reserve (FFR) and coronary flow reserve (CFR) assessments found that untreated vessels with abnormal FFR but intact CFR do not have non-inferior outcomes compared to those with an FFR greater than 0.8 and a CFR greater than or equal to two when treated medically.

Physiology-guided percutaneous coronary intervention optimization strategy may lead to improved outcomes

Results from the randomized controlled TARGET FFR trial show that while a physiology-guided percutaneous coronary intervention (PCI) optimization strategy did not achieve a significant increase in the proportion of patients with final FFR ≥0.90, it reduced the proportion of patients with a residual FFR ≤0.80 following PCI.

Results from the FORECAST trial reported

In the FORECAST randomized clinical trial, the use of fractional flow reserve management derived from computed tomography (FFRCT) did not significantly reduce costs but did reduce the use of invasive coronary angiography (ICA).

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.

Strategic interventions in dairy production in developing countries can help meet growing global demand for milk

Low dairy consumption is common among low- and middle-income countries (LMICs); however, with the demand for milk in these countries projected to increase over the next few decades, there is an opportunity to improve the lives of millions of people from the nutritional benefits of dairy products. Feed the Future Innovation Lab for Livestock Systems hosted the "MILK Symposium: Improving Milk Production, Quality, and Safety in Developing Countries" at the 2019 American Dairy Science Association Annual Meeting to address factors that cause low dairy consumption in LMICs and discuss strategies to address them. The Journal of Dairy Science invited speakers to submit articles on topics from the symposium to reach a wider audience.
