Star-shaped glial cells, the so called “astroglia”. Glial means glue. As befits their name, until now these cells have been regarded merely […]

The electrically excitable cells in the nervous system that transport information, also called neurons, can produce short binary, all-or-nothing reaction-spikes of voltage, which travel as a pulse along the specialized extensions (axons) which causes the release of neurotransmitters. The spikes contain information about the world around the subject: what do I see, smell, hear, taste, […]

When you are forced to use a prosthetic device, it usually is quite cumbersome and has disadvantages. But, with this is going to change with the help of rockets. The new prototype rocket-powered mechanical arm can lift about 9 to 12 kilograms – three to four times more than current commercial prosthetic arms – and […]

Some neurons, which are sensitive for the amount of glucose in blood, appears to play an important roll in the cause of Diabetes mellitus type 2 (adult-onset diabetes). These neurons become active when more glucose appears in the blood, which causes an increase in sugar-uptake. If these neurons are made insensitive, artificially, for glucose, diabetes […]
