In this brief, at times controversialâ even radicalâvolume. Dr. Ian C. Hale guides us through likely scenarios and gives us life-saving recommendations for effectively dealing with the next waves of the COVID-19 pandemic. This is a must read for public policy makers, medical professionals, and those mapping out their financial future in the post-corona world.
SpaceX launched 60 Starlink satellites atop a Falcon 9 rocket from Pad 39A at NASAâs Kennedy Space Center in Florida on Oct. 6, 2020. The private spaceflight company has now launched well over 700 of these internet-providing satellites into orbit.

First we kick them, then we give them the tools they need to destroy all of humanity. Good job, us.
Scientists in China have invented a liquid metal that can shape-shift and propel itself around a course all by itself.
Ramping Up
Johnson announced that the U.K. would invest about ÂŁ160 million ($207 million) that will go toward factories that would develop new turbines as well as floating offshore turbines themselves. In order to power every home in the U.K., those turbines would need to generate about 40 GW of power, Engadget reports. Thatâs four times the nationâs current wind energy output.
âYour kettle, your washing machine, your cooker, your heating, your plug-in electric vehicle, the whole lot of them will get their juice cleanly and without guilt from the breezes that blow around these islands,â Johnson announced at the U.K. Conservative party conference.
Urine turned into hydrogen fuel

Whizz electrocatalyst frees the hydrogen from âliquid goldâ
US researchers have developed an efficient way of producing hydrogen from urine â a feat that could not only fuel the cars of the future, but could also help clean up municipal wastewater.
Using hydrogen to power cars has become an increasingly attractive transportation fuel, as the only emission produced is water â but a major stumbling block is the lack of a cheap, renewable source of the fuel. Gerardine Botte of Ohio University may now have found the answer, using an electrolytic approach to produce hydrogen from urine â the most abundant waste on Earth â at a fraction of the cost of producing hydrogen from water.

Scientists from a Belgian university have built a solar-powered machine that can turn urine into drinkable water. They deployed it at a 10-day music and theater festival in central Ghent, Belgium. The experiment was a success as the scientists were able to recover a 1,000 litres of unconsumed water, which will be used to make Belgian beer, from the urine of several partygoers.
The worldâs sea floor is littered with an estimated 14 million tonnes of microplastics, broken down from the masses of rubbish entering the oceans every year, according to Australiaâs national science agency.
The quantity of the tiny pollutants was 25 times greater than previous localised studies had shown, the agency said, calling it the first global estimate of sea-floor microplastics.
Researchers at the agency, known as CSIRO, used a robotic submarine to collect samples from sites up to 3,000 metres (9,850 feet) deep, off the South Australian coast.
Quantum mechanics arose in the 1920s, and since then scientists have disagreed on how best to interpret it. Many interpretations, including the Copenhagen interpretation presented by Niels Bohr and Werner Heisenberg, and in particular, von Neumann-Wigner interpretation, state that the consciousness of the person conducting the test affects its result. On the other hand, Karl Popper and Albert Einstein thought that an objective reality exists. Erwin Schrödinger put forward the famous thought experiment involving the fate of an unfortunate cat that aimed to describe the imperfections of quantum mechanics.
In their most recent article, Finnish civil servants Jussi Lindgren and Jukka Liukkonen, who study quantum mechanics in their free time, take a look at the uncertainty principle that was developed by Heisenberg in 1927. According to the traditional interpretation of the principle, location and momentum cannot be determined simultaneously to an arbitrary degree of precision, as the person conducting the measurement always affects the values.
However, in their study Lindgren and Liukkonen concluded that the correlation between a location and momentum, i.e., their relationship, is fixed. In other words, reality is an object that does not depend on the person measuring it. Lindgren and Liukkonen utilized stochastic dynamic optimization in their study. In their theoryâs frame of reference, Heisenbergâs uncertainty principle is a manifestation of thermodynamic equilibrium, in which correlations of random variables do not vanish.
