More importantly, the spray which has to be periodically re-applied, should greatly reduce the amount of water needed for flushing. This is important, as enormous quantities of this scarce resource for used for this purpose. I presume that they will test that the material sprayed does not create any environmental problems?

https://www.snopes.com/fact-check/ohio-school-religion-answers/) seemingly has the power to require teachers not to mark down students for giving answers (on evolution or the flatness of the Earth?) that are scientifically wrong, so long as they are rooted in religious (all religions or just Christianity?) teaching. This seems very suspect to me, as the point of science teaching is to gain an understanding of the scientific method (where you make observations, come up with a testable hypothesis and do tests on that explanation that can be independently confirmed by other scientists). There is nothing wrong with people having religions (if they want one) but this aspect of life is not scientifically testable. Surely students can be required to give an accurate account of the scientific thinking behind ideas even when it differs from their internalised beliefs?

https://www.theguardian.com/environment/2019/nov/13/air-pollution-particles-linked-to-brain-cancer-in-new-research). This strongly suggests that this air pollution (which often exceeds legal limits in UK cities), will increase the rates of brain cancers. It is somewhat concerning that many schools in urban areas are near busy roads and problems can be exacerbated by idling cars doing the 'school run'. The brains of children may be especially vulnerable.

The increased weight, however, results in more greenhouse gases being emitted than would otherwise be produced on a trip of that distance. It seems, to some people, that the airlines are more concerned about their bottom line than about their effects on climate change. All this at a time when the very concept of regular air travel is being challenged.

The product is said to be convincing, even when viewed under a microscope and it is actually made from the same material (keratin) as the real horn that is used in Chinese medicine. The hope is that the introduction of faux rhinoceros horn will, by substantially driving down the price, make poaching much less rewarding. It would, of course, also be useful to confirm that rhinoceros horn has no medical benefits.
