The Middle Ages certainly were far from being science-friendly: Whoever looked for new findings off the beaten track faced the threat of being burned at the stake. Hence, the contribution of this era to technical progress is deemed to be rather small. Scientists of Karlsruhe Institute of Technology (KIT), however, were inspired by medieval mail armor when producing a new metamaterial with novel properties. They succeeded in reversing the Hall coefficient of a material.
The Hall effect is the occurrence of a transverse electric voltage across an electric conductor passed by current flow, if this conductor is located in a magnetic field. This effect is a basic phenomenon of physics and allows to measure the strength of magnetic fields. It is the basis of magnetic speed sensors in cars or compasses in smartphones. Apart from measuring magnetic fields, the Hall effect can also be used to characterize metals and semiconductors and in particular to determine charge carrier density of the material. The sign of the measured Hall voltage allows conclusions to be drawn as to whether charge carriers in the semiconductor element carry positive or negative charge.

A research team has shown that a key difference between neurogenic and non-neurogenic tissues is cross-linking proteins causing stiffness, a discovery that could be used to create new brain injury therapies.
Researchers compared the proteomes of regions in the brain that are neurogenic (neural stem cell niches) and those that are not (cerebral cortex). The scientists hope that by establishing how these tissues are different, future therapies for brain injury may be able to activate tissues to produce new neurons to repair the brain.
Bill Gates has commissioned the construction of the Aqua superyacht, designed by Dutch studio Sinot. At 370ft long and 50ft wide, it is powered by two tanks of liquid hydrogen.
Antidepressant-soil.
Soil microbes have been found to have similar effects on the brain as prozac, without the negative side effects and potential for chemical dependency and withdrawal.
It turns out getting in the garden and getting dirty is a natural antidepressant due to unique microbes in healthy organic soil. Working and playing in soil can actually make you happier and healthier.
