Credit: CC0 Public Domain Researchers at Karolinska Institutet in Sweden have used DNA origami, the art of folding DNA into desired structures, to show how an important cell receptor can be activated in a previously unknown way. The result opens new avenues for understanding how the Notch signaling pathway works and how it is involved … Read more
Influence of Light on Plant Ionic-Osmo-Hydraulic Properties and Water Homeostasis. The impact of the complete light spectrum on plant ion and water transport is widely recognized. The light spectrum affects hydraulic conductance at multiple levels, from individual cells to the entire organism. The left side of panels a–c (blue shaded background) describes the processes that occur when … Read more
It was found that male mice with no ability to produce the MC2 protein were unable to form the connection between the tail and the head of the sperm and the mice became infertile. The microscope images clearly show the difference in the sperm. Credit: Kexin Zhang Mice lacking a certain gene are unable to … Read more
