New Kilogram Definition

Good article about changing the definition of what a kilogram really is.

The kilogram has been defined since 1889 by a shiny piece of platinum-iridium held in Paris. All modern mass measurements are traceable back to it – from micrograms of pharmaceutical medicines to kilos of apples and pears and tonnes of steel or cement.

The problem is, the “international prototype kilogram” doesn’t always weigh the same. Even inside its three glass bell jars, it gets dusty and dirty, and is affected by the atmosphere. Sometimes, it really needs a wash.

Awesome Use of Technology

By using a brain implant, people who are paralyzed.

Three people paralyzed from the neck down have been able to use unmodified computer tablets to text friends, browse the internet and stream music, thanks to an electrode array system called BrainGate2. The findings could have a major impact on the lives of those affected by neurologic disease, injury, or limb loss.
The system uses an array of micro-electrodes implanted into the brain which decode, in real time, the neural signals associated with the intention to move a limb. The three people involved in the trial had electrode grids implanted over part of their motor cortex — the area of the brain that helps control movement — which picked up neural activity indicating they were thinking about moving a cursor on the screen. Those patterns were then sent to a virtual mouse that was wirelessly paired to the tablet.
