August 04, 2025MES Livestream 101: How Controlled Opposition Works
https://3speak.tv/watch?v=mes/wyovipai
Join me as I explore the tactics that controlled opposition disinformation agents use to keep the truth hidden behind gated roads. And this is no more evident than in the coverup of the use of directed free energy technology on 9/11 to turn entire skyscrapers into dust.

August 02, 2025Animal Form and Function: Reproduction
https://3speak.tv/watch?v=mes/cyciamwy
In this video I go over a quick review of animal reproduction, which can be done in two ways: asexual or sexual. Nearly all animals engage in some form of sexual reproduction, where haploid gametes (motile spermatozoa and stationary ova) merge to create diploid zygotes, which then develop into a hollow sphere called a blastula. Most animals then invaginate to form a gastrula with a digestive chamber and two or three separate germ layers, which later differentiate to form tissues and organs.
Some animals undergo asexual reproduction, which don't involve the fusion of gametes or the change in the number of chromosomes, often times resulting in a genetic clone. An example is the incredible Hydra which reproduces via fragmentation by budding out into a new Hydra. The Hydra do not appear to die of old age, or age at all, and can regenerate even if chopped up into pieces! 🤯

July 30, 2025Animal Form and Function: Hormonal Control
https://3speak.tv/watch?v=mes/ldvrxfmv
In this video I go over hormones, which are signalling molecules that are secreted by internal glands and transported through the blood to regulate distant organs. In vertebrates, the hypothalamus as the neural control center that links the nervous system to the endocrine system via the pituitary gland, which secretes hormones controlling growth, metabolism, and reproduction. The famous pineal gland produces melatonin which regulates sleep and the circadian rhythm. The pineal gland also looks like a pine cone, and appears to have deep occult connections as it appears through historical artifacts and art. Interestingly, even the Eye of Horus resembles a cross-section of the human brain, namely near the hypothalamus.
I also go over the ovaries and testicles, which serve both functions in reproduction but also as endocrine glands releasing hormones. Finally, I go over an extensive table on organs that serve secondary endocrine functions and their major hormones they release.

July 29, 2025Animal Form and Function: Nervous System
https://3speak.tv/watch?v=mes/nwpltvdi
In this video I go over the nervous system, which is a complex network of neurons (and glial cells for structural and metabolic support) that process sensory information and generate behaviors. Neurons transmit signals through electrical and chemical synapses, which have narrow gaps, called gap junctions, between cells of 3.8 nm distance for electrical synapses and 20 to 40 nm for chemical synapses. Electrical synapse transmit ions while chemical synapses transmit neurotransmitter molecules. The nervous system for most vertebrates consist of the central nervous system (CNS) (brain and spinal cord), and the peripheral nervous system (PNS), which consists of nerves that connect the body to the CNS. Motor nerves transmit signals from the CNS to the body while sensory nerves transmit from the body to the CNS. The PNS is further subdivided into the somatic, autonomic, and enteric nervous systems. Somatic nerves mediate voluntary movement. The enteric nervous system controls the gastrointestinal system, and which often gets the gut being referred to as the "second brain". The autonomic system is activated in case of emergencies (sympathetic system), or when in a relaxed state (parasympathetic system). Both the enteric and autonomic systems are involuntary.
Finally, I discuss sensory receptors, such as those that sense pressure changes (mechanoreceptors), those that detect changes in light (photoreceptors), or chemoreceptors which detect chemicals in the mouth (taste) or air (smell). I also dive into how the human eye is literally a camera!

July 26, 2025🔬#MESExperiments 50: Magnets in Repulsion Atwood Machine Drop Tests
https://3speak.tv/watch?v=mes/uvggztws
In #MESExperiments 50 I measure the drop rates of magnets in attraction, magnets in repulsion, and a nonmagnet when placed in an Atwood machine with the same counterweight. The magnets in repulsion fell 12.11% slower than the magnets in attraction, while the non-magnet fell 3.64% faster than the magnets in attraction. While not conclusive, these results strongly suggest that magnets in repulsion do fall slower in gravity as Boyd Bushman, senior engineer at Lockheed Martin, had claimed. I will perform this experiment at higher heights in the near future so stay tuned!

July 20, 2025Animal Form and Function: Muscles and Movement
https://3speak.tv/watch?v=mes/hgscnpzw
In this video I go over the muscular system of animals, which for vertebrates consists of skeletal, smooth, and cardiac muscles. The skeletal muscles are mostly attached to bones via tendons, and are voluntarily controlled. The smooth muscles are involuntary non-striated muscles (hence smooth) and line the walls of many internal organs and structures like blood vessels and the digestive tract. I also discuss the Sliding Filament Theory to explain how muscles contract via the smallest units of striated muscles, the sarcomeres. I also go over how a worm moves via peristalsis (contraction of its circular muscles) and how an insect flies via its asynchronous flight muscles.
