  Toxicology - Poison and Its...

  Toxicology, the study of poisons and their effects on living organisms, has deep historical roots dating back thousands of years. The earliest civilizations recognized the dangers of certain substances and documented their effects, often intertwining them with myths, medicine, and warfare. The origins of toxicology can be traced to ancient Egypt, Mesopotamia, Greece, and Rome, where early scholars and physicians laid the groundwork for what would eventually become a scientific discipline. 
  Ancient Egyptian texts, such as the Ebers Papyrus (circa 1550 BCE), contain some of the earliest references to poisons, including plant-based toxins and venomous animal bites. Egyptian priests and physicians were aware of toxic substances, both as medicinal agents and as potential means of assassination. Similarly, Mesopotamian records describe the use of poisons in both healing practices and criminal activities. 
  In ancient Greece, the philosopher and physician Hippocrates (circa 460–370 BCE) discussed the effects of poisons and the importance of dosage in determining whether a substance was harmful or beneficial. His work influenced later Greek and Roman physicians, including Dioscorides, a first-century CE pharmacologist who compiled De Materia Medica, an extensive guide to medicinal and poisonous substances derived from plants, animals, and minerals. The Greek philosopher Theophrastus (circa 371–287 BCE) also contributed to early toxicology by documenting the properties of various poisonous plants.

  In Search of Darkness - The...

  Dark matter is one of the greatest mysteries in the universe. Despite being invisible and undetectable by traditional means, it accounts for a significant portion of the universe’s mass. It has been a subject of scientific inquiry for over a century, and yet, it remains largely elusive. The term "dark matter" was first coined in the 1930s by astronomer Fritz Zwicky when he observed that galaxies in clusters were moving much faster than expected based on the visible matter they contained. Zwicky hypothesized that there must be some unseen mass, which he referred to as "dark matter," to explain the extra gravitational pull. This idea was revolutionary at the time, but it took decades for the concept of dark matter to gain widespread acceptance in the scientific community. 
  In the following years, astronomers and physicists continued to gather indirect evidence for dark matter’s existence. The observation of galaxy rotation curves provided another compelling clue. Galaxies, such as our Milky Way, were found to rotate faster at their outer edges than could be explained by the visible matter alone. If only the mass of the stars and gas were considered, the galaxies would not be able to maintain their rotation speeds without breaking apart. However, the additional gravitational influence of dark matter seemed to explain this discrepancy, pointing to its presence. 
  Despite this evidence, scientists still have no direct way to detect dark matter. It does not emit, absorb, or reflect light, making it invisible to traditional telescopes and detectors. The most that can be done is to observe its effects on visible matter, radiation, and gravitational forces. The hunt for dark matter has since become a driving force in astrophysics and particle physics, with scientists developing new methods and tools to try and detect it.

  The Internet Con - How to Seize...

  When the tech platforms promised a future of "connection," they were lying. They said their "walled gardens" would keep us safe, but those were prison walls. 
  The platforms locked us into their systems and made us easy pickings, ripe for extaction. Twitter, Facebook and other Big Tech platforms hard to leave by design. They hold hostage the people we love, the communities that matter to us, the audiences and customers we rely on. The impossibility of staying connected to these people after you delete your account has nothing to do with technological limitations: it's a business strategy in service to commodifying your personal life and relationships. 
  We can - we must - dismantle the tech platforms. In The Internet Con, Cory Doctorow explains how to seize the means of computation, by forcing Silicon Valley to do the thing it fears most: interoperate. Interoperability will tear down the walls between technologies, allowing users leave platforms, remix their media, and reconfigure their devices without corporate permission. 
  Interoperability is the only route to the rapid and enduring annihilation of the platforms. The Internet Con is the disassembly manual we need to take back our internet.
