television tube contains lead, chromium and mercury inside it, so you don’t want to just throw it away. Instead of throwing it away automatically, ask yourself, can you put it in a guest bedroom, is it a TV that the kids could use. It is important to find other things to do with the set before throwing it away. If you are going to throw it away, you need to make sure that you are bringing it to the proper recycling center; otherwise the lead and mercury have a possibility of the water and the soil

These risk factors include but are not limited to diet, mercury poisoning, the body’s inability to use vitamins and minerals, digestive tract changes, and vaccine sensitivity. Parents are also worried that vaccines play a role in their child being diagnosed with autism and believe that the small amount of mercury is a

The Letter to the Editor, by Carlie Towns, published in ‘The Hobart Mercury’, on July 18, 2015, argues very strongly against ‘Puppy Farming’, whilst also questioning the source of pets in many pet shops. This is an issue that has been much discussed in the media recently and Towns is tapping into the general concern about the treatment of breeding dogs, simply to provide puppies for sale to an unsuspecting public. In a bitterly-attacking and assertive tone, Towns directs her piece to parents, pet

CONSTELLATIONS and ASTROLOGICAL SIGNS * What is a Constellation? * A constellation is a group of stars that appears to form a pattern or picture like Orion the Great Hunter, Leo the Lion, or Taurus the Bull. Constellations are easily recognizable patterns that help people orient themselves using the night sky. * In modern astronomy, a constellation is an internationally defined area of the celestial sphere. These areas are grouped around asterisms, patterns formed by prominent stars

also have studied the insides of other planets to learn about Earth's core. While they can't get good seismic data from Mercury or Venus, researchers have found ways to make the comparison. In research published in the journal Science this year, Zuber and her colleagues at MIT examined Mercury's core by using the planet's magnetic field to their advantage. "The fact that it [Mercury] has a magnetic field tells us that it's iron and that part of it is molten," Zuber says. Without at least a partially

In 1789, Antoine Lavoisier published a list of 33 chemical elements, grouping them into gases, metals,nonmetals, and earths.[42] Chemists spent the following century searching for a more precise classification scheme. In 1829, Johann Wolfgang Döbereiner observed that many of the elements could be grouped into triads based on their chemical properties. Lithium, sodium, and potassium, for example, were grouped together in a triad as soft, reactive metals. Döbereiner also observed that, when arranged
