If you're interested in the biological or health effects of various chemicals, try to look up the Safety Data Sheet, or "SDS" or "MSDS", for that chemical compound. Going to your favorite search engine and plugging in your chemical of interest to the search term "SDS" or "MSDS" will almost always get you to some kind of answer — either what you're looking ...

This is a great biological question! It asks a lot about how empirical science is done in the field of modern biology! I'm glad we encourage such questions from curious people who want to learn more. There is another paper here that discusses using a similar frequency range of UVC radiation (207-222 nm) as a biocide: The biophysical reason is that, due ...

Some graphs about the ovarian cycle mention only the follicular phase and luteal phase, and the ovulation just as a point in time, not a phase, for example, here: Source: Differencebetween.com In this case, the LH surge starts in the follicular phase and peaks at ovulation or shortly before it. Some other graphs also show the "periovulatory" phase (or "...

First of all a disclaimer, I am not an expert in this subject, but I have read these studies and came to this understanding. There might be a chance I get a lot of stuff wrong. From another paper by the same authors, this time regarding 222nm UVC: We have previously shown that 207-nm light emitted by a filtered krypton-bromine (Kr-Br) excilamp has ...

Preamble: The problem with questions on evolution Obviously, evolutionary biology is a reputable discipline, but unfortunately there two types of questions on evolution that are often posted on this site that I believe are of little value and can lead to dangerously unscientific habits of mind. The first is questions of the type “Why did such and such ...

The life of the radicals decides how far they move. This paper https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4310837/#!po=6.92308 has a table of half lives of radicals, the longest lasting ones (the radical of nitrous oxide and nitrogen dioxide) have half lives of seconds. Diffusion theough the skin would be slow Technically the problem is "reactive oxygen ...

As cooperative entities (cells) form a larger body, the larger body takes up functions that are beyond the scope of an individual cell. This involves storing and processing information at a higher level of abstraction and quantity. Your blood cell wouldn't be able to understand what a computer is, in the same way your blood cell doesn't expect you to ...

I answered a related question here that may be helpful. Some initial notes: Your first bullet point ("99%") is to my reading talking about not the total genome size but the data that they actually assembled- e.g. for 99% of nucleotides, we are 99.99% that the nucleotide at that position is not some other nucleotide, but there may be other positions not ...
