Fossilized Tick Carrying Pathogens in Mammalian Blood Cells Discovered in 15-Million-Year-Old Amber

fossilized tick

Ticks have been pathogen-carrying parasites for a very, very long time. A new discovery in a specimen of fossilized amber, roughly 15 million to 20 million years old, reveals a tick encased adjacent to mammalian blood cells infected with microbes resembling those in the order Piroplasmida. Today, related pathogens are known to cause Babesiosis and […]

Nicotine and Other Natural Chemicals Protect Bees from Parasites

Bumble bees infected with a common intestinal parasite are drawn to flowers whose nectar and pollen have a medicinal effect, a new study shows. The findings, soon to be published in the journal Ecology, suggest that plant chemistry could help combat the decline of bee species. The researchers previously found in lab studies that nectar […]

Insecticidal Nesting Materials May Help Birds on the Galápagos Islands

Birds on the Galápagos Islands known as Darwin’s finches have been threatened since the 1990s by parastic, blood-sucking flies (Philornis downsi) that were accidentally introduced to the islands via ships and boats. The flies now infest all land birds there, including most of the 14 species of Darwin’s finches, two of which are endangered. Fewer […]
