A new study led by University of Minnesota astrophysicists shows that high-energy light from small galaxies may have played a key role in the early evolution of the Universe. The research gives insight into how the Universe became reionized, a problem that astronomers have been trying to solve for years.
The research is published in
The Astrophysical Journal, a peer-reviewed scientific journal of astrophysics and astronomy.
First-of-its-kind method cryopreserves fruit fly embryos in liquid nitrogen
Cryopreservation, or the long-term storage of biomaterials at ultralow temperatures, has been used across cell types and species. However, until now, the practical cryopreservation of the fruit fly (Drosophila melanogaster)-;which is crucial to genetics research and critical to scientific breakthroughs benefiting human health-;has not been available. To keep alive the ever-increasing number of fruit flies with unique genotypes that aid in these breakthroughs, some 160,000 different flies, laboratories and stock centers engage in the costly and frequent transfer of adults to fresh food, risking contamination and genetic drift, said Li Zhan, a mechanical engineering postdoctoral associate with the University of Minnesota College of Science and Engineering and the Center for Advanced Technologies for the Preservation of Biological Systems (ATP-Bio).

Although brain imaging is performed on head-fixed mice, recording neural activity in freely behaving mice has remained a challenge. To address this, researchers report the development of a unique head-mounted mini-microscope device that allows them to image complex brain functions of freely moving mice in real time over a period of more than 300 days.
The device, known as the mini-MScope, offers an important new tool for studying how neural activity from multiple regions of the cortex contribute to behavior, cognition, and perception. The groundbreaking study provides new insight into fundamental research that could improve human brain conditions such as concussions, autism, and Alzheimer’s and Parkinson’s diseases, as well as better understanding the brain’s role in addiction.

Researchers from the University of Minnesota Twin Cities College of Science and Engineering and Medical School have developed a unique head-mounted mini-microscope device that allows them to image complex brain functions of freely moving mice in real time over a period of more than 300 days.
The device, known as the mini-MScope, offers an important new tool for studying how neural activity from multiple regions of the outer part of the brain, called the cortex, contribute to behavior, cognition and perception. The groundbreaking study provides new insight into fundamental research that could improve human brain conditions such as concussions, autism, Alzheimer s, and Pa
