Everyone has experienced an afterimage at some point in their life. Yet, most people don’t realize what they are. An afterimage is a faded illusion of an object continued to be seen for a brief moment, even after you have stopped looking at the actual object. Sometimes the colors are very vivid and bright, while other times, the colors are dull or even inverse or opposite from the original color. Afterimages can all look very different, varying from blotches of light, faded images of the original object, or of course in reversed colors. Afterimages happen all the time, try to recognize it the next time it happens to you.
What does the future look like to you? Perhaps you see quantum computing as the next big leap or envision a future powered by cold fusion. Maybe you think Artificial Intelligence will be the biggest game changer of all, but what you probably don’t have in mind is the most dated piece of hardware we have, a processor 100 million years old: the human brain.
What is that strange sound outside?

Protein is required for an animal cell to perform activities necessary for its survival. Though protein is made by the ribosome (an organelle), many other organelles (specialized cell parts that performs a specific function) within the cell contributes to its production and delivery. Therefore, for a cell to be able to survive, all organelles within the cell must be able to properly function. It is important to have a proper understanding of these organelles before it is possible to understand how protein is produced. Parts of a cell that contribute to protein production includes the nucleus (containing nucleolus and DNA and is surrounded by a nuclear membrane), ribosomes, the endoplasmic reticulum, vesicles, the Golgi body, and the cell membrane. The definitions and functions of these parts will be specifically discussed in the paragraph(s) below.
Coming to the realization that there just might be a "start over" button for the entire universe can be pretty unnerving... not knowing for sure whether the physics we use in our world today are legitimate is even more terrifying. Yet here I am with another unproven theory. This one's about the evolving False Vacuum Theory.
Debunkers would call psychic archaeology a fraud, but as I have an interest in the field of archaeology in general, I want to explore how my abilities can help me as an archaeologist. Archaeology is a field of many subheadings such as historical archaeology, or as known as the archaeology of the modern period. I’m interested in the actual science of real archaeology, not just pseudoscience as I want to be a real scientist, in addition to law school and my M.D. UCLA has an archaeology department besides the law department I want to enroll in when I go back to school and get my grades up.
Fusion energy has been known as the gateway to our civilization's future. Fusion reactions yield the largest amount of energy per unit of mass than any other reaction that we know of, and it is in our near technological reach. The amount of energy produced from fusion fuel would be so large that, once commercially stabilized, the fuel would be so inexpensive and require such modest amounts to operate, that electricity would eventually be virtually free. This, however, is the bliss of idealism. We have yet to actually achieve remotely close to any of these claims, and it seems as though that almost-in-reach phase is lasting much longer than we anticipated.
Hormones are organic chemicals which arise in the body and are connected with behaviour, mood and development, helping to maintain homeostasis. They are produced and released by specialized glands called endocrine glands (J. Nelson 2000). They can be divided into three categories: amino acid derivates, peptides, and proteins and steroids (Preece 2012). Hormones are the most familiar to people because of the use and abuse of steroid hormones for different aims, such as contraception and bodybuilding (D. G. Hardie 1991). In this essay, I will explain the main concepts of the endocrine system with a regard to behaviour and in particular sexual behaviour.
A little over four years ago, Time magazine published, "Hawking: Is He All He's Cracked Up To Be?" Key quotes from the first few paragraphs:
Real science demands inquiry, skepticism, and ability to prove theories using a hypothesis. Believing in pseudoscience can cause great harm to the mind. There is much logic used in the acquirement and interpretation of data. A theory is a systematic explanation that can reinterpret existing data so that new predictions can be made about new data. Using hypothesis becomes a matter of testing statements about something, which is linked to our broader understanding of the past. Archaeologists are interested in how people lived in the past through the study of gravesites featuring objects buried with the dead.
Out of every living organism on Earth, humans identify the closest with a virus. We expand uncontrollably, we destroy our host (our host being Earth,) and we have no stable means of not eradicating ourselves without expanding to a new planet.
Occam’s razor is a term attributed to William of Ockham (1287-1347), an English Franciscan friar, philosopher and early scientist, who took a vow of poverty, and who helped come up with a concept that is used in science today which determines that the fewest assumptions is the easiest. Scientists have changed the meaning of the term “Occam’s razor” throughout the centuries since it was first coined. Isaac Newton said of Occam’s razor that, “We are to admit no more causes of natural things than such are both true and sufficient to explain their appearances.” In other words, the simplest explanation rather than a complex explanation is always the better explanation.
