Global warming may limit spread of dengue fever, new research finds

Infection with dengue virus makes mosquitoes more sensitive to warmer temperatures, according to new research led by Penn State researchers. The team also found that infection with the bacterium Wolbachia, which has recently been used to control viral infections in mosquitoes, also increases the thermal sensitivity of the insects.

How Does COVID-19 Spread Differently Than The Flu?

Each year, scientists look to the Southern Hemisphere to get a clue as to how flu season up north might play out. The flu season below the equator, which typically runs June through August, gives us an idea of which strains are circulating and how intense the Northern Hemisphere’s flu season, which usually sees an uptick around early November, could be.

How superspreading is fueling the pandemic — and how we can stop it

On Saturday, thousands of people were gathering inside the BOK Center in Tulsa, Oklahoma, a city where Covid-19 cases have risen steeply since May 31, at a rally for President Donald Trump’s reelection campaign. There may not be room for physical distancing in the arena, which can hold 19,000 people. Each person who registered has signed a waiver to say they will not sue Trump if they get sick with Covid-19.
