1. A two-month-old strike at South Africa's PGM mines that shows no signs of ending. 2. A stand-off between the West and Russia, which together with South Africa control more than 70% of global platinum mining output. 3. A surge in investor interest in physical platinum-backed exchange traded funds. 4. Futures and options speculators in platinum build positions which are the most bullish in over a year. 5. Number one platinum consumer, the European auto industry growing at least 5% this year, after falling for six straight years. http://www.mining.com/platinum-etf-holdings-surge-to-record-high-55968/
-A few months ago, more than 500 tons of fish (freshwater fish) were killed because of a lack of oxygen in the water. This was caused by volcano chemicals, industrial wastes, and other long-term causes. -Scientists have recently discovered that less oxygen triggers grass hopper molting which would benefit farmers because the less oxygen there is the shorter time between molts and the shorter lifespan for grass hoppers, which would equal less hungry grasshoppers so farmers can farm in peace. -Scientists have recently discovered that if oxygen levels in the blood are low, oxygen therapy can be used. What oxygen therapy is a therapy that is the administration of oxygen as a medical intervention, which can be for a variety of purposes in both chronic and acute patient care.
1. Obama burnt more than 35,000 gallons of fuel on Earth Day, emitting 375 TONS of carbon dioxide. 2. Carbon in atmosphere could warm planet for centuries. 3. LONDON, April 28 (Reuters) - European carbon prices rebounded on Monday from a two-week low as higher power prices encouraged utilities to snap up cheap carbon permits. 4. The low-carbon aviation fuel, which will be produced in India, is claimed to have half the carbon footprint of standard fossil fuel. Virgin Atlantic was the first airline to fly a plane on bio-fuel in February 2008. 5. The growth in China’s carbon footprint is largely thought to be accounted for by its massive infrastructure projects as it prepares to join the ranks of developed countries.

Current events and interesting facts about silver:
1) For the Super bowl, Tiffany & Co. made a 7-pound silver trophy as the prize. 2) Silvery Jewelry in the U.S. is boosting and 73% of jewelry retailers increased sales last year according to "Silver Jewelry Buying Trends" (a survey conducted) and the silver Jewelry was 36%. 3) Silver cars are less likely to become involved in accidents that cars with colors. This was proven in New Zealand where they conducted an expirement and 1,000 cars with colors were in an accident. 4) Scientists have known about silver's ability to kill harmful bacteria and, recently, have used this knowledge to create consumer products containing silver nanoparticles (a particle with dimensions less than 100 nanometres). 5) An archaeologist at the University of Liverpool is examining more than 1,000 Roman silver coins from museums around the world in order to establish their true economic value. 6) Scientists in India have discovered a silver-based gel that cures burns and infections on skin.
1. Tantalum has become really important in the recent years because it is used to make capacitors for phones. 2. In the past Apple has had some problems for mining Tantalum, because they used a way of slavery, but now they have sorted it out and have lowered the hours of work and pay is hirer 3. The richest supply of Tantalum is in the Congo and right now there is a war there so it is pretty ricky mining there. 4. Tantalum is also very toxic to extract so apple also had a problem in that area, but they say that is solved and that nobody has to worry about it. 5. Tantalum conducts heat and electricity so well that they can use it inside phones and engineers can start to make smaller phones.
1) Iodine is essential for the development of the brain as it is needed to build some of the body's hormones. 2) Iodine deficiency might lower UK children's IQ 3) Iodine deficiency affects 2 out of 3 women in the UK 4) it is advised that children eat products containing iodine such as fish and dairy products, 5) Lack of iodine is one of the leading cause of preventable brain damage in the world.
1. Lithium, a key ingredient in lightweight batteries, is already powering the modern world, and could be key to getting the world to reduce its reliance on fossil fuels. 2. For lithium is also the first of the alkali metals - like its near kin sodium and potassium, it will react spontaneously to water, though not quite as violently as those other two. 3. Lithium is helpful for charging batteries. 4. "We think of batteries as producing an electrical current, sending electrons around a circuit," explains chemistry professor Andrea Sella of University College London. 5. It is conventional with lithium batteries to refer to the negative electrode as the anode, and the positive electrode as the cathode. The two electrodes, with an electrically insulating separator between them, are often rolled up like a Swiss roll.
1. It has been discovered that Xenon was used by Russian athletes to improve their athletic performance in the Sochi 2014 Winter Games. Xenon increases levels of erythropoietin, also known as EPO, a hormone that encourages the formation of red blood cells. 2. Mysteriously, most of the gas xenon that scientists expected to find in Earth's atmosphere is missing. Now, researchers say they might have the answer to this puzzle: This noble gas, which usually does not bond with other atoms, may chemically react with iron and nickel in Earth's core, where it's held. 3. The rare gas xenon reacts with fluorine to give xenon tetrafluoride. The product is the first xenon molecule having four bonds and containing only one other element. 4. The noble gas xenon reacts with water ice at exceedingly high temperatures and pressures – conditions that are found within the interiors of planets such as Uranus and Neptune. 5. The use of xenon gas to boost performance, a method allegedly pioneered by Russian athletes, could be banned by the world anti-doping agency (WADA).

A group of Washington State University students win international awards at the annual Hydrogen Student Design Contest with their designs for a hydrogen fueling plan for cars. 3. Honda creates bottled water from water produced from their hydrogen emissions, which is perfectly safe to drink. 4. Researchers at the Swiss Federal Institute of Technology have used a novel laser approach to control the vibrations of a water molecule involved in the reaction of converting methane into hydrogen. 5. Student researcher at Rutgers University leads to a new method for developing clean hydrogen fuel.
helium: 1st event Party Town, the biggest company that sells helium, has helium shortages at the moment (7 percent). The prices rose up by 20 percent. Also like many companies make buyouts, Party City carries a hefty debt load—$2.3 billion—and can ill afford input cost increases. This is worrying considering that helium is a nonrenewable gas. 2st event Scientists had proved that argon and hydrogen be substituted by helium. However, as the helium is very light and unflammable, therefor it is the best replacement. 3rd event New uses for helium were recently discovered: cooling medium for nuclear reactors, pressurizing liquid fuel rockets, as a gas for supersonic wind tunnels and protective gas in growing silicon and germanium crystals, in titanium and zirconium production, and to cool MRI machines. 4th event The chemical elementhelium exists in a liquid form only at the extremely low temperature of -269 degrees Celsius. Liquid helium has many uses, such as fabrication of metals, healthcare, diving, aerospace production. 5th event BBC news has informed that helium, the gas, which is formed by the decay of radioactive rocks in the earth's crust, accumulates in natural gas deposits and is collected as a by-product of the gas industry, should not be wasted carelessly on balloons, and should be used for people helping purposes. The scientists believe that this element is rare, and the U.S. government should limit is use, especially Texas, the national helium reserves 25 % of helium.

1. Neon is the fourth most abundant element in the atmosphere, although it is only 0.0018 percent of Earth's atmosphere. 2. Because of its large refrigeration capacity, in the past few years, neon has actually begun to be used in refrigerators to keep cold. 3. National Geographic has found a new ice cream, made to glow in the dark. This ice cream has been made using synthesized protein from jellyfish, which includes the element neon. The product, created by Charlie Harry Francis, is assured to be safe, but can cost about $220 per scoop. 4. The Neon Energy Company in Vietnam has new exploration dates, in July to drill for neon. 5.
