Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on **Biology, Chemistry, Neuroscience, Medicine, Psychology**

Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...".

Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists.

Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here[1]. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience.

Will diseases that are caused by defective genes be able to get cured not only with gene-therapy prior to birth like any of mitochondrial disease and will there be cure that make such defects not transferrable to children?

And what is the ethical implications of manipulating genetic structure of individuals and will it affect the necessary diversity of population?

After hearing about microplastics being detected in our bloodstream, are there studies being conducted on the effects of microplastics on a cellular level? What do we know so far and how plastic might be affecting our health and any changes plastic might be making to us microscopically. Thanks!!!

I often hear it's a slow decent to death from 30yo with the brain having stopped growing/changing, genetic mistakes piling up, immune system degradation, weakening muscles, etc.

Surely there's SOME advantage to being 40? Anything good? Or am I a walking corpse?

Medicine/Biology: When preventing or diagnosing cancer we often get asked if there's cancer history in our family. My dad died from gastric cancer. My skin is very pale and I asked for two black spots on it to get removed in order to prevent skin cancer.

Does my dad having cancer of any kind increases the chances of his descendants getting any kind of cancer? Or does him having gastric cancer only increases the chances of his descendants getting that specific type of cancer? How does that work/why is cancer history in the family important?

Chemistry: Can you split a powdered medicine capsule in half by dilituting it in 1 cup of water and then splitting the solution into two half cups? Would the two half cups of water contain approximately the same amount of powder?

Biology?: When someone is diabetic and needs to pee a lot. Why is that?

I had a semi argument with a friend and want to see if someone smarter knows.

I heard multiple times that drinking ice cold drinks in summer should be avoided, as it costs the body a lot of energy to reheat from the inside.

Could you achieve a calorie deficit by only hydrating via chewing ice cubes?

Do you think it’s possible to have “giant leap” advances in medicine anymore without human experimentation like the Minnesota Starvation study?

Chemistry: if we had the ability to directly manipulate the contents of an atom’s nucleus, could we adjust the number of neutrons in a radioactive element like uranium to create a stable isotope? Or is every element beyond lead destined to be unstable no matter what?

Biology/Psychology

Do we understand why some humans have an innate desire to form bonds with nature? Animals in particular. (Sorry gardeners.) I don't really mean domestication, and I don't really mean pets either.

I mean that first instinct to bond with wild animals. That first person who threw some scraps to a wolf because he wanted to. Has that, for lack of a better term 'precursor drive to bond' been studied?

Biology:

Most of what ive read about metabolism and nutrition talks about how carbohydrates and fats are digested to create energy. What is the role of protein in providing energy for us? If only a small portion is used to power us, and eating protein without stressing your muscles doesn't really build muscle, what happens to the rest of the protein we eat?
