Planaria worms demonstrate how cells communicate and grow new tissues
Forsyth Institute research with the flatworm, planaria, offers new clues for understanding restoration of body structures. Researchers at The Forsyth Institute have discovered how the worms cells communicate to correctly repair and regenerate tissue. Forsyth scientists have found that gap-junction (microscopic tunnels directly linking neighboring cells) communication contributes to this signaling. This research, led by Dr. Michael Levin, underlies principles that can potentially offer insight into human regeneration.
The restoration of body structures following injury requires both an initiation of growth and an imposition of the correct morphology upon the regenerating tissue. Understanding this process is crucial for both the basic biology of pattern formation, and for developing novel biomedical approaches. Planaria have powerful regeneration capability that makes them ideal for studying this process. When the worms are cut in half, the bottom section of the worm grows a head and the upper section a tail. Scientists have suspected that the ability of previously adjacent cells (on either side of the cut) to adopt radically different fates, as is the case with planaria where the cells have to decide whether to build a head or a tail, could be due to long-range signaling, which allows the determination of position relative to - and the identity of - remaining tissue.

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
