Do lactose intolerant people have less of a blood sugar increase after consuming dairy?

Lactose is a sugar, so that got me thinking: if we don't have an enzyme to digest it, do we have less sugar intake and, therefore, less of a blood sugar increase?

Why do most animals on earth live “roughly” the same time frame?

Posted: 15 Apr 2022 05:08 PM PDT

Most animals survive between like 5 years and 100 years. I know some outliers like turtles end up living to like 150 but what's stopping things from living to 1000, 10'000?

I'm guessing there's some smaller beings or 1/not-very-many celled organisms that last a long time but I'm not aware of anything that's not microscopic that lasts ages. How come?

If you plant the same species of tree in different hemispheres, do they still flower at the same time?

For example, if you plant a cherry tree in the southern hemisphere, will it still flower in march-april? or in semptember-october (spring)?

How is the screening for a specific monoclonal antibody carried out?

Posted: 15 Apr 2022 11:01 AM PDT

I'm currently studying for final and I can't seem to understand how a single clone is screened for. Doubts; how are cultures of single clones obtained? How do we screen for a monoclonal antibody for a specific epitope? I understand it could be done evaluating the supernatants of the cultures via Elisa to see if we're producing antibodies for the antigen, I just can't seem to fully understand.

What is the chromatin organization like in quiescent stem cells?

Posted: 15 Apr 2022 04:37 PM PDT

Is it more tightly coiled around hetereochromatin than it is in normal cells? (allowing it to "age more slowly than more metabolically active cells"?)

Could the water on Earth have literally come from Mars? Or, could the water from Mars have made it to Earth?

Random question about Earth and Mars…

So, is there a way that the water here on Earth used to actually be on Mars? In other words, we are thought that the current atmospheres of the each of the terrestrial planets is original, having been there since its formation. But obviously they have changed. I know the carbon and oxygen cycles very much participated in the formation of our own atmosphere, but I haven't heard a satisfying answer to the drastic rise in oxygen levels long ago, other than life itself created it. So, as a crazy thought, I wonder if the water and other gasses of the various inner planets could have actually transferred from one to the other? Like, in a process analogous to a mass spectrometer, could all the water have slowly bled off of Mars and found its way to earth, perhaps as the sun changed and matured? Could all the sulfur have accumulated on Venus by the same process?

effect of premarital sex on marriage quality?

Posted: 15 Apr 2022 01:05 PM PDT

I've been digging into research trying to answer the question: "what are the evidence-based effects of either having premarital sex or the time till sex on marriage quality?". I've found a number of articles from the early 2000's and 2010's that have looked into this, but I have found it difficult to sus out if these are "agenda-driven" studies.

Given the close ties of abstinence till marriage stances and numerous religious institutions, I am finding it hard to tell (since this is not my field of study) whether the studies are credible. Can anyone with some familiarity with this type of research help shed some light on this? In particular, I see a lot of work funded by either the National Marriage Project at the University of Virginia, the Wheatley Institution(BYU) and or BYU's School of Family Life. It's not to say these institutions are incapable of producing good science, but rather that I can see a potentially concerning conflict of interest. What's more, I have found contradictory results from analyses performed from non-family-based research fields, eg economics, vs those that are explicitly family focused (e.g journal of family health, etc...). for instance: https://doi.org/10.1111/ecin.12206 vs http://before-i-do.org/ (concatenation of various research from some of the aforementioned sources).
