Quantity over quality? Different bees are attracted to different floral traits

When it comes to deciding where they’re going to get their next meal, different species of bees may be attracted to different flower traits, according to a study led by researchers at Penn State and published in PNAS Nexus.

A led by Penn State researchers compared two treatments for a common uterine infection, called clinical metritis, that can lead to serious health problems for dairy cows. One treatment was based on antibiotics and the other was not. Both treatments had a similar clinical cure rate in mild cases of the disease. Credit: Penn State. Creative Commons

New research finds sex-specific regions of the brain can relieve the detrimental effects of chronic stress in male and female mice. Left: Schematic showing a cortical microcircuit with three types of interneurons expressing somatostatin (SST), parvalbumin (PV) or vasointestinal peptide (VIP) and their distinct patterns of innervation of glutamatergic output neurons (PNs), with thin lines representing axons that send chemical signals and the thicker lines of PNs representing dendrites that receive information. There is selective innervation of the distal ends of PN dendrites by axons of SST neurons. Right: Increased activity of SST neurons by genetically induced disinhibition, on top right, or by chemogenetic activation of SST neurons in the medial prefrontal cortex, on bottom right, leads to stress resilience and facilitates the reversal of the detrimental behavioral effects of stress exposure in male but not female mice.
