Analyzing genetic ‘signatures’ may give insight into what stresses wild bees

A new method of examining gene expression patterns called landscape transcriptomics may help pinpoint what causes bumble bees stress and could eventually give insight into why bee populations are declining overall.

New research lends insight into the regulatory control of gene expression in the deadliest of the malaria parasites, Plasmodium falciparum, and provides opportunities for the development of new therapeutic approaches against the disease. PfSnf2L, in red, is an essential malaria parasite protein for developing from the asexual ring to the sexual transmission stage — shown at top with the arrow illustrating the trajectory of various stages of sexual development. When the PfSnf2L enzyme is inhibited by the small molecule, NH125, in green, this leads to disordered DNA packaging. Changes in DNA packaging with active — the white line — and inactive PfSnf2L enzyme — the blue line — are depicted. When the DNA packaging is disrupted, the necessary information for parasite development can no longer be read out and the malaria parasites die thereby blocking transmission.

Native bee populations can bounce back after honey bees move out

Managed honey bees have the potential to affect native bee populations when they are introduced to a new area, but a study led by researchers at Penn State suggests that, under certain conditions, the native bees can bounce back if the apiaries are moved away.
