Measuring Martian winds with sound

Martian landers have been able capture measurements of wind speeds -- some gauging the cooling rate of heated materials when winds blow over them, others using cameras to image 'tell-tales' that blow in the wind -- but there's still room for improvement. Researchers now demonstrate a novel sonic anemometric system featuring a pair of narrow-band piezoelectric transducers to measure the travel time of sound pulses through Martian air. The study accounted for variables including transducer diffraction effects

Archaeologists have collected data which indicates the presence of a large-scale pre-Columbian fish-trapping facility. Discovered in the Crooked Tree Wildlife Sanctuary (CTWS), the largest inland wetland in Belize, the team dated the construction of these fisheries to the Late Archaic period (cal. 2000-1900 BCE), pre-dating Amazonian examples by a thousand years or more.

Impact of climate change on water resources will increase price tag to decarbonize the grid

A new study warns that current plans to achieve zero emissions on the grid by 2050 vastly underestimate the required investments in generation and transmission infrastructure. The reason: these plans do not account for climate change's impacts on water resources. Specifically, changes in water availability caused by climate change could decrease hydropower generation by up to 23% by the year 2050, while electricity demand could increase by 2%. Read more ›
