New Zealand City’s ‘Official Wizard’ Was Taken Off Its Payroll Because Magic Is Dead
A New Zealand city seems to have left itself vulnerable to a revenge hex.
The city council of Christchurch announced that it will stop paying its official wizard $16,000 ($10,400 USD) a year in December, New Zealand news site Stuff reported.
Ian Brackenbury Channell (aka the Wizard) has been serving as the city’s appointed necromancer since the olden days of 1998. Over the past few decades he has made a total of $368,000 (roughly $258,825 USD) “to provide acts of wizardry and other wizard-like-services — as part of promotional work for the city of Christchurch.”

The production of molecular positronium
Circa 2007
When intense positron bursts are implanted into a thin film of porous silica, di-positronium (Ps2) is created on the internal pore surfaces, providing experimental proof of the existence of the molecule. Using a more intense positron source, it may be possible to form a Bose–Einstein condensate of Psf2 molecules, which would be of significant fundamental interest and a milestone on the path to produce an annihilation gamma-ray laser.

Scientists Say We Need to Rethink How We Dispose of Satellites
The term, “casualty risk” doesn’t literally mean humans will be smashed by falling satellites, but there is an increasing risk of satellite collisions, which could hinder or even spell disaster for future orbital missions. And, satellites de-orbited without control could pose a danger to property or the well-being of some on the surface.
In other words, it’s time to rethink the way we dispose of satellites.
Full Story:
What goes up, must come down.
Or at least, for satellites, it should.
Rich nations warned hogging Covid jabs will lead to huge global death toll
Exclusive: UK scientist says giving booster jabs rather than sharing doses equitably will cause hundreds of thousands of avoidable deaths.
The U.S. Preventive Services Task Force’s proposed changes to recommendations for using low-dose aspirin to prevent a first heart attack or stroke closely align with guidelines from the American College of Cardiology and the American Heart Association.
The discovery of red blood cells acting as micro-electrodes opens new doors in medical research
In a paper published in Scientific Reports, academics at the University of Surrey have discovered that biological cells generate an electric field voltage that appears outside and not just within, meaning each cell acts as a tiny electrode. Since this voltage impacts how cells interact with their environment, including the way cells stick to one another, this has significant potential implications for future medical treatments.
Since the 1790s, scientists have known that electricity plays a role in the function of life, with the discovery in the 1940s that every cell contains a voltage that controls many of its functions. This is particularly the case in muscle and nerve cells but has also been shown to play an important role in diseases such as cancer.
However, until now, this voltage has always been understood to be contained within the cell. Through intricate experiments with red blood cells, the Surrey-led research team has shown that the voltage appears outside the cell as well. This means that cells effectively act as tiny transmitters, electrically changing the environment around them. Similar results in other types of biological cells could play a significant role in determining new types of medical treatment.
