In molecular biology, a **vector** is a DNA molecule used as a vehicle to transfer genetic material into a host cell. Vectors are essential tools in genetic engineering, cloning, and various biotechnological applications. They can carry genes of interest, facilitating the introduction of these genes into cells for various purposes, such as gene expression, gene therapy, or the production of proteins.
The Warburg hypothesis, proposed by the German biochemist Otto Warburg in the 1920s, suggests that cancer cells primarily rely on aerobic glycolysis for energy production, even in the presence of sufficient oxygen, which is different from normal cells that typically generate energy through oxidative phosphorylation in the mitochondria. This phenomenon, known as the "Warburg effect," indicates that cancer cells preferentially convert glucose to lactate instead of fully oxidizing it to carbon dioxide and water.
ZMapp is an experimental therapeutic drug that was developed for the treatment of Ebola virus disease. It is a type of monoclonal antibody therapy, which means it is designed to target and neutralize the Ebola virus in the body.

The Expected Utility Hypothesis (EUH) is a fundamental concept in economics and decision theory that describes how rational individuals make choices under conditions of uncertainty. According to this hypothesis, individuals evaluate risky options by considering the expected utility rather than the expected outcome or monetary value alone. **Key Concepts of the Expected Utility Hypothesis:** 1. **Expected Utility**: This refers to the sum of the utilities of all possible outcomes, each weighted by its probability of occurrence.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
