River erosion can shape fish evolution
A new study of the freshwater greenfin darter fish suggests river erosion can be a driver of biodiversity in tectonically inactive regions.
How sweet it is: The fruit fly gut influences reproduction by ‘tasting’ fructose
A research group has found that in fruit flies (Drosophila melanogaster), circulating fructose derived from dietary sugar is needed for enhanced egg production after mating. In this species, circulating fructose is required for an increase in germline …
Researchers successfully induce primate oocytes in the lab
The many types of cells in the human body are produced through the process of differentiation, in which stem cells are converted to more specialized types. Currently, it is challenging for researchers to control the differentiation of stem cells in the…
Keeping time: Understanding the master clock in the brain
Researchers found that, in neurons that produced the neuropeptide NMS, the interaction between molecules SIK3 and HDAC4 has a critical role in sleep regulation through both the length of the circadian period and sleep homoeostasis. Given the similariti…

New study provides novel insights into the cosmic evolution of amino acids
All biological amino acids on Earth appear exclusively in their left-handed form, but the reason underlying this observation is elusive. Recently, scientists uncovered new clues about the cosmic origin of this asymmetry. Based on the optical properties…
