cell biology is a bunch of processes. Just reading isn't always enough, you should make sure you know all the steps of each process and imagine what would happen if you were to take away one of the components or tamper with the system in some way (ex: add ATPgammaS to a system containing dynamin etc)

depends on light intensity and wavelength present, and I don't think there's an absolute database of information for something like this anywhere

developing an inhibitor for a protease is different from curing a disease. that may sound promising, but HIV protease inhibitors already exist, and obviously we still have AIDS around. While that may be an important achievement chemically (I can't read ACS papers to save my life), it may not even wo...

pretty much all animals studied. See here a review from nature m The whole reason why people started looking for CR mimmetics was the observation that respiration increases in CR, which meant that the classic "less ROS, less damage" paradigm was wrong. Subsequently David Sinclair found res...

1) Yes, but the big pharma companies are putting the vast majority of their money in the automated method, not in looking for natural compounds.

2) Do you have a peer-reviewed source for that? I tend to be skeptical

that is not an error in the data, it is an error in using probability. Probability can only be used forward, not backward. Let me give you a couple of easy examples to make my point. 1. Take a deck of cards and deal them between you and your friend. After that ask yourself "What is the probabil...

well generally when you want to measure activity of an enzyme in vitro you need to design an assay to measure it. So you will need to have a substrate there ( a histone tail fragment) and a way to detect the methylation (no idea how). One problem i don't think you would have is detecting between his...

this article is stupid. It claims that when a gene is duplicated, both copies are ALWAYS under purifying selection. That cannot be true. If it were, then: 1. pseudogenes wouldn't exist 2. down syndrome wouldn't be bad - if two copies of a gene were better than one because one copy would be just a ba...

@surealworld No offense, but you're a scientific idiot. Just because two organisms have a common ancestor doesn't mean they have to produce offspring. Humans and tulips have a common ancestor, it's just that it's an extremely distant common ancestor. The common ancestor of horses and donkeys is very...

you can't believe some of evolution, but not all of it. For a regular person who doesn't care to shift through the details, evolution goes down to this: natural selection is the only force that can shape complexity from simplicity and chance organisms over time. Through natural selection organisms c...
