Research on the rate at which mosquitoes land on people in field tests and lab tests finds that common arm-in-cage test results differ significantly from those found in large-room or field tests. The findings point the way toward making tests of mosquito repellents more aligned with real-world conditions.
A new study by CDC researchers provides a county-level map of the presence of ticks confirmed to be carrying the bacteria that cause Lyme disease—though the distribution of ticks that are capable of carrying it is much wider.
A study of Loxosceles spiders in Iran, Turkmenistan, and Afghanistan documents two new species, one of which the researchers have named for Canadian singer-songwriter Leonard Cohen.
