Super Big Black Holes
![]() Public Domain by Brandon Defrise Carter (assumed) [CC0]
| At the centre of most galaxies - including our own - there are super big black holes. Black holes can grow by absorbing surrounding mass, but once that is gone they normally do not find additional material to feed on. So how did the super big black holes form in the first place? There is a new possible answer which assumes that at the beginning of the universe fast gas streams were moving through the universe feeding these black holes. |

| Bacteria are often viewed as isolated beings. However, as has been found out they live often in colonies and can even communicated with each other using electrical signal based on potassium ions not unlike the communication between neurons in a human brain. The findings may lead in the long run to new ways of treating bacterial infections. |

| In brains affected by Alzheimer's disease, abnormal tau proteins lead to an influx of calcium in the neurons, which then does serious damage also by making more tau proteins abnormal. There is now some understanding why this cascade of bad events can be stopped by HDAC6 inhibitors. This understanding may lead to an effective medication against Alzheimer's disease. |
