A New Wave of Bills Takes Aim at Science in the Classroom. Why this vaxed v. unvaxed study is not valid. For the last few days, people opposed to vaccines have been posting a link to a study called Pilot comparative study on the health of vaccinated and unvaccinated 6- to 12- year old U.S. children.

Why this vaxed v. unvaxed study is not valid

The lead author is Jackson State, MS, University professor, Anthony R. Mawson. This study is not valid and here is why. First of all, I need to explain what is meant by validity and reliability, with regards to science. The University of California, Davis, has a very good synopsis. Appeal to false authority – who is Tetyana Obukhanych. 1.16k Shares There are so many annoying issues about the antivaccination cult, that most of us can’t even keep up with it.

Appeal to false authority – who is Tetyana Obukhanych

If only they would provide evidence published in high quality, peer reviewed journals (yes, a high standard, but if we’re talking about public health, a high standard is required), the fake debate would move into a real scientific discussion. One of their favorite feints against real evidence is to push people, like Tetyana Obukhanych, who appear to have great credentials, but once you dig below the surface, not much is there. The dark allure of conspiracy theories, explained by a psychologist.

Questioning the Mpemba effect: hot water does not cool more quickly than cold. Debate heats up over claims that hot water sometimes freezes faster than cold. It seems logical to expect cold water to freeze faster than hot, but some experiments have suggested the opposite.

Debate heats up over claims that hot water sometimes freezes faster than cold

There’s now a new explanation for why hot water might freeze faster than cold under certain conditions. The phenomenon, known as the Mpemba effect, may be due to the properties of the chemical bonds that link up neighboring water molecules, a team of chemists reports. Yet other researchers contend that the effect doesn’t exist at all. References to quick-freezing hot water date back to the early days of science: Aristotle reported observing hot water freezing faster than cold. In the 1960s, a Tanzanian student named Erasto Mpemba noticed that ice cream solidified faster when put into the freezer steaming hot. Acopian BirdSavers — Prevents birds from flying into windows.

Scientists may be underestimating how quickly the Earth’s plants can change location in response to climate change, according to a study from the University of B.C.

Climate change: Plant evolution spurs fast migration, UBC study finds

As the global average temperature rises, the comfort zones of many plants and trees are easing north or into higher elevations, but the speed with which they move is being driven by evolutionary responses. Plants cultivated to evolve were able to move 200 per cent further across difficult landscapes over six generations than plants with no evolutionary ability. In favourable landscapes, the advantage was only 11 per cent.
