We have been told time and again that climate change will enhance mosquito populations, thus bringing increased incidences of disease such as malaria and dengue fever. Fortunately, science is ahead of the climate-to-mosquitoes issue (even if it may be overblown) as we see in this story. Gene editing wipes out mosquitoes in the lab Researchers…

A new study published in Scientific Reports reports that tidal measurements reveal something about the masses of ocean water, and therefore the climate of the past, and act as “liquid climate archives.” The currents and water masses of the deepest part of the ocean play a fundamental role in the evolution of the planet’s climate, because they affect…
