Blood plasma protein fibrinogen interacts directly with nerve cells to cause brain inflammation
Before soluble fibrinogen, a blood plasma protein, is converted into insoluble fibrin molecules that can toxically accumulate outside blood vessels in the brain, fibrinogen connects directly with neurons and can cause a damaging inflammatory reaction, …
Diet restricted size of hunter-gatherer societies
Short growing seasons limited the possible size of hunter-gatherer societies by forcing people to rely on meat, according to a recent study. After looking at population size for the roughly 300 hunter-gatherer societies which existed until quite recent…
Livestock antibiotics and rising temperatures disrupt soil microbial communities
Community ecologists investigated the interactive effects of rising temperatures and a common livestock antibiotic on soil microbes. The research team found that heat and antibiotics disrupt soil microbial communities — degrading soil microbe efficien…
Scientists issue new climate adaptation ‘scorecard’
A new study offers a ‘scorecard’ for climate adaptation projects — a set of 16 criteria that can be used to evaluate climate adaptation projects and inform their design.
Why did glacial cycles intensify a million years ago?
A study says the Mid-Pleistocene Transition may have been linked to previous erosion of continental soils that subsequently allowed glaciers to stick to the underlying hard bedrock more efficiently.
Why nitrous oxide emissions should factor into climate change mitigation
A newly published study found that a range of agricultural soils produce nitrous oxide emissions in sufficient quantities to contribute to climate change. The researchers compared soils with various moisture content and found agricultural soils are cap…
