Humans are exposed to toxic chemicals and microplastics at all stages in the plastics life cycle. The effects of microplastics on human health are a growing concern and an actively increasing area of research. Tiny particles known as microplastics (MPs), have been found in various environmental and biological matrices, including air, water ...
D-IX is a methamphetamine-based experimental performance enhancer developed by Nazi Germany in 1944 for military application. [1] [2] The researcher who rediscovered this project, Wolf Kemper, said, "the aim was to use D-IX to redefine the limits of human endurance."
Nazi human experimentation was a series of medical experiments on prisoners by Nazi Germany in its concentration camps mainly between 1942 and 1945. There were 15,754 documented victims, of various nationalities and age groups, although the true number is believed to be more extensive.
Zyklon B (German: [tsyˈkloːn ˈbeː] ⓘ; translated Cyclone B) was the trade name of a cyanide-based pesticide invented in Germany in the early 1920s. It consists of hydrogen cyanide (prussic acid), as well as a cautionary eye irritant and one of several adsorbents such as diatomaceous earth .
A company called Tomorrow Biostasis is focusing on human cryopreservation in the hopes it can eventually reverse death. The new Berlin startup has already preserved the bodies of about 10 deceased ...
The effects of low-level radiation on human health are not well understood, and so the models used, notably the linear no threshold model, are open to question. [ 106 ] Given these factors, studies of Chernobyl's health effects have come up with different conclusions and are sometimes the subject of scientific and political controversy.
Since 1962, the microwave auditory effect or tinnitus has been shown from radio frequency exposure at levels below significant heating. [34] Studies during the 1960s in Europe and Russia claimed to show effects on humans, especially the nervous system, from low energy RF radiation; the studies were disputed at the time. [35] [36]
The medical effects of the atomic bomb upon humans can be put into the four categories below, with the effects of larger thermonuclear weapons producing blast and thermal effects so large that there would be a negligible number of survivors close enough to the center of the blast who would experience prompt/acute radiation effects, which were observed after the 16 kiloton yield Hiroshima bomb ...
