Researchers at The Ottawa Hospital and the University of Ottawa have discovered an 18-digit code that allows proteins to attach themselves to exosomes - tiny pinched-off pieces of cells that travel around the body and deliver biochemical signals. The discovery, published in Science Advances, has major implications for the burgeoning field of exosome therapy, which seeks to harness exosomes to deliver drugs for various diseases.

MIT researchers developed a non-invasive imaging technique that enables laser light to penetrate deeper into living tissue, capturing sharper images of cells. This could help clinical biologists study disease progression and develop new medicines. 

Scientists at St. Jude Children’s Research Hospital leveraged fundamental features of chemical building blocks to transform chemical reaction analysis from minutes to milliseconds.

How can we explain the morphological diversity of living organisms?  Although genetics is the answer that typically springs to mind, it is not the only explanation. By combining observations of embryonic development, advanced microscopy, and cutting-edge computer modelling, a multi-disciplinary team from the University of Geneva (UNIGE) demonstrate that the crocodile head scales emerge from the mechanics of growing tissues, rather than molecular genetics. The diversity of these head scales observed in different crocodilian species therefore arises from the evolution of mechanical parameters, such as the growth rate and stiffness of the skin. These results, published in the journal Nature, shed new light on the physical forces involved in the development and evolution of living forms.
