science news 5.3.2019

Today's selection of science news. Links are normally to press releases on EurekAlert (at the bottom end I may also add a couple of newspaper stories). I include quotes from the summary (using quotation marks) in cases where the title alone doesn't reveal what the story is about. My own thoughts appear without quotation marks, if I have any.

Forecasting mosquitoes' global spread
New prediction models factoring in climate, urbanization and human travel and migration offer insight into the recent spread of two key disease-spreading mosquitoes -- Aedes aegypti and Aedes albopictus. The models forecast that by 2050, 49 percent of the world's population will live in places where these species are established if greenhouse gas emissions continue at current rates.

Turning algae into fuel
A team of University of Utah chemical engineers have developed a new kind of jet mixer for creating biomass from algae that extracts the lipids from the watery plants with much less energy than the older extraction method. This key discovery now puts this form of energy closer to becoming a viable, cost-effective alternative fuel

Human 'footprint' on Antarctica measured for first time
The full extent of the human 'footprint' on Antarctica has been revealed for the first time by new IMAS-led research which used satellite images to measure stations, huts, runways, waste sites and tourist camps at 158 locations. The study, which also included researchers from the Australian Antarctic Division and University of Wollongong, found that more than half of all large ice-free coastal areas of Antarctica have now been disturbed by human activity.


Due to humans, extinction risk for 1,700 animal species to increase by 2070
sounds like a conservative estimate to me ...
