Synaptic networks in brains of rodent models of autism

These negative effects are associated with increased production of a specific neuronal glutamate receptor, which modulates the signal transmission between neurons. An excess of these receptors inhibits the adaptation of the synaptic signal transmission during the learning process, thus disrupting the development and function of the brain in the long term.Of major importance is the finding that the impaired development of the neuronal circuit in the brain is reversible. When the scientists reactivated the production of neuroligin-3 in the mice, the nerve cells scaled down the production of the glutamate receptors to a normal level and the structural defects in the brain typical for autism disappeared. Hence, these glutamate receptors could be a suitable pharmacological target in order to stop the developmental disorder autism or even reverse it.

World first experiments on sensor that may revolutionise everything from medical devices to unmanned vehicles
The new sensor - capable of detecting vibrations of living cells - may revolutionise everything from medical devices to unmanned vehicles.
Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
