  • Single Particle Electron Microscopy Reconstruction of the Exosome Complex Watch video protocols on JoVE - . Journal of Visualized Experiments (JoVE) is a scientific journal publishing video articles on biological experiments filmed at leading research institutions. JoVE is the first video journal indexed in PubMed. To see more of this protocol go to Single Particle Electron Microscopy Reconstruction of the Exosome Complex Using the Random Conical Tilt Method This video protocol was filmed at Yale University. Single particle electron microscopy (EM) reconstruction has recently become a popular tool to get the three-dimensional (3D) structure of large macromolecular complexes. Compared to X-ray crystallography, it has some unique advantages. First, single particle EM reconstruction does not need to crystallize the protein sample, which is the bottleneck in X-ray crystallography, especially for large macromolecular complexes. Secondly, it does not need large amounts of protein samples. Compared with milligrams of proteins necessary for crystallization, single particle EM reconstruction only needs several micro-liters of protein solution at nano-molar concentrations, using the negative staining EM method. However, despite a few macromolecular assemblies with high symmetry, single particle EM is limited at relatively low resolution (lower than 1 nm resolution) for many specimens especially those without symmetry. This technique is also limited by the size of the molecules under study, ie 100 kDa for negatively stained ...
  • Chris Busby Explains Why Uranium Is Bad For You (Part 2) Chris Busby of the University of Liverpool explains precisely how uranium - including natural, enriched, and depleted uranium - causes health problems. I don't know how useful it is to someone without a science background, at least introductory molecular biology, but Busby explains it extremely well in a convincing and frightening presentation. This information has not thus far been acted on by any regulatory agencies. The presentation was made in February 2008 as part of the public interventions in the environmental assessment of AREVA's proposed Midwest uranium mine in northern Saskatchewan. Busby was asked to present by the Saskatoon-based Inter-Church Uranium Committee Education Cooperative.

  • LIBYA: DIRTY BOMBS? Depleted Uranium: US & UK's DIRTY TACTICS There's a suspicion that armour-piercing, radioactive weapons are being deployed by foreign forces on Libya. The US says 'it's not aware' depleted uranium's being used, while the UK's flatly denying it. Political observer Christoph Hoerstel says NATO's chief members have a habit of using uranium weapons - and it's likely Libya's in line. Uranium Health Effects A discussion of chemical and radiological health effects associated with exposure to uranium and its compounds. Chemical Toxicity Exposure to uranium can result in both chemical and radiological toxicity. The main chemical effect associated with exposure to uranium and its compounds is kidney toxicity. This toxicity can be caused by breathing air containing uranium dusts or by eating substances containing uranium, which then enters the bloodstream. Once in the bloodstream, the uranium compounds are filtered by the kidneys, where they can cause damage to the kidney cells. Very high uranium intakes (ranging from about 50 to 150 mg depending on the individual) can cause acute kidney failure and death. At lower intake levels (around 25 to 40 mg), damage can be detected by the presence of protein and dead cells in the urine, but there are no other symptoms. Also, at lower intake levels, the kidney repairs itself over a period of several weeks after the uranium exposure has stopped. Radiological Toxicity Several possible health effects are associated with human exposure to radiation from uranium. Because all uranium ...
  • Isolation of Uranium Yellowcake from Ore In this video, uranium is concentrated from its ore through a series of precipitations, which eventually yields a form of yellowcake, uranyl peroxide. Please remember to take proper precautions when working with a radioactive heavy metal such as uranium and its salts. Gloves, eye protection, and a dust mask are necessary. For processing, uranium ore is dissolved into hydrochloric acid, oxidized with bleach, precipitated with ammonia, filtered, leached with carbonate, filtered, neutralized with hydrochloric acid, precipitated with hydrogen peroxide, and filtered. The uranium produced by this procedure could in no way be considered weapons-grade or enriched. The enrichment process requires millions of dollars in investment and is impossible for any entity short of a national government to produce. This uranium maintains the isotopic ratio found within the earth's crust and is actually less radioactive than the ore from which it was processed due to the absence of more radioactive decay products of uranium, such as radium, protactinium, and other unstable nuclei produced by the spontaneous fission of U238. Though ore chemistry varies by locality, this process is generalized for any uranium on an acid-soluble matrix. This process was inspired by and based off of:
  • Inorganic Chemistry, Hayton Group Professor Trevor Hayton studies the redox behavior of inorganic compounds and uses a wide variety of inorganic synthesis techniques.
  • How would you know you've found uranium ore The scale on ***og geiger is multiplied 10x, and it shows higher counts (3500 cpm) because it also detects alpha radiation.
  • uranium ore + nitric acid = uranyl nitrate this video tells you how to turn a black lump of pitchblende into a green fluorescing mass. =) warning - concentrated nitric acid is one of the strongest acids in the world. touching it can lead to severe injuries, and it easily reacts to form poisonous gas. make sure you know how to handle and neutralize it as well as discard of the mess you made if you decide to handle it.
