A unique amino acid for brain cancer therapy https://www.sciencedaily.com/releases/2017/06/170623085053.htm ScienceDaily: Latest Science News urn:uuid:37a01ebf-ca8b-56f9-347e-cc60c052b082 Fri, 23 Jun 2017 07:50:53 -0500 Photodynamic therapy is often used to treat brain tumors because of its specificity — it can target very small regions containing cancerous cells while sparing the normal cells around it from damage. It works by injecting a drug called a photosensitizer into the bloodstream, where it gathers in cells, and then exposing the drug-filled cells to light. When the photosensitizer is exposed to this light, it emits what is known as a reactive oxygen species (ROS) that causes the cells to die. Protein mingling under blue light https://www.sciencedaily.com/releases/2017/06/170623085006.htm ScienceDaily: Latest Science News urn:uuid:2d23c6f9-bf52-e1ae-2e97-2d8bca1b849a Fri, 23 Jun 2017 07:50:06 -0500 One of the current challenges in biology is to understand rapidly-changing phenomena. Interestingly, only a small fraction of them is due to proteins acting in isolation, the majority of biological events are regulated by proteins acting together in clusters. Researchers have developed a new tool, called "CRY2clust", to trigger protein cluster formation in response to blue light. This new technique has a much faster response rate and higher sensitivity to light than existent methods. Today in Space!

Cells in fish's spinal discs repair themselves https://www.sciencedaily.com/releases/2017/06/170622122008.htm ScienceDaily: Latest Science News urn:uuid:de17b813-5675-d989-4681-16d48ace5ef4 Thu, 22 Jun 2017 11:20:08 -0500 A unique repair mechanism has been discovered in the developing backbone of zebrafish that could give insight into why spinal discs of longer-lived organisms like humans degenerate with age.
