Francis Torres from The University of Western Australia has developed the mirror device at the heart of a new amplifier technology, which uses an interaction between a high-powered laser and mirror motion to magnify subtle metal, temperature and biological vibrations so they are more easily detected.
Genes are not enough to explain the difference between a skin cell and a stem cell, a leaf cell and a root cell, or the complexity of the human brain. Genes don’t explain the subtle ways in which your parents’ environment before you were conceived might affect your offspring.
Another layer of complexity—the epigenome— is at work determining when and where genes are turned on and off.
Ryan Lister is unravelling this complexity. He’s created ways of mapping the millions of molecular markers of where genes have been switched on or off, has made the first maps of these markers in plants and humans, and has revealed key differences between the markers in cells with different fates.
Stem cells generated from adult cells still retain a memory of their past despite being reprogrammed, Australian scientists have found. Now scientists think they can teach the cells to forget their past.
Fiona Bull can tell if your city is making you sick just by looking at how easy it is to walk around—and she plans to use this knowledge of good city design to help reduce global physical inactivity by 10 per cent by 2025.
