Global warming may slow the spread of dengue fever

Dengue fever is a potentially lethal disease of humans that is caused by a virus transmitted in the saliva of certain mosquitoes. Recent studies led by Penn State researchers have found that mosquitoes of the species Aedes aegypti that are infected with dengue virus are less tolerant of the higher temperatures associated with global warming.

Mosquitoes that carry dengue might not survive rising temperatures

Disease-carrying mosquitoes are expected to venture into new territory due to climate change and urbanization, but new research suggests that higher temperatures may curb the spread of at least one infection: dengue fever.

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.

Will There Be Black Friday Shipping Delays? Prepare To Be Patient

Black Friday is getting closer and closer, and as much as everyone loves a good deal, the influx in people shopping online, given the ongoing coronavirus pandemic, is something to be mindful of. If you remember the beginning of the pandemic, when nearly everyone went on an online shopping bender in a flurry of panic, you'll also remember the serious shipping delays and health concerns for those working in fulfillment and delivery centers. Now that it's almost time for holiday shopping, the question on everyone's mind is: Will there be Black Friday shipping delays?
