The scientists find a way to make concrete stronger. And it is a way to recycle the industrial waste. The new concrete mix fly ash and blast-furnace slag, both of them are called pozzolans. The pozzolans are the key point to make the concrete stronger than the normal concrete. It also help reduce the concrete’s [...]

Artificial embryo twinning is the relatively low-tech version of cloning. As the name suggests, this technology mimics the natural process of creating identical twins. In nature, twins occur just after fertilization of an egg cell by a sperm cell. In rare cases, when the resulting fertilized egg, called a zygote, tries to divide into a [...]

How do nuclear weapons work?
March 31st, 2009 · No Comments · Chemistry, Physics
There are two basic ways that nuclear energy can be discharge from an atom: Nuclear fission – You can split the nucleus of an atom into two smaller fragments with a neutron. This method usually concerns isotopes of uranium (uranium-235, uranium-233) or plutonium-239. Nuclear fusion -You can bring two smaller atoms, usually hydrogen or hydrogen isotopes (deuterium, [...]
