Models Show Lasers Can Produce Energy Using Hydrogen-Boron as Fuel

Energy created by lasers could be the way of the future. Researchers have used models and they show that lasers can produce "cold" energy by nuclear fusion. A new generation of fast, powerful lasers makes this possible. To achieve fusion a short, carefully controlled pulse is required. The pulse target is hydrogen and boron. Creating neutrons is not the objective because they cause radioactivity.

The Australian research is duplicating what is going on at the National Ignition Facility at the Lawrence Livermore National Laboratory in the United States, but they are using deuterium-tritium fuel.

A single laser pulse can generate 500 times more electricity than all the power stations in the US. At first the research team did not believe hydrogen-boron fuel would work. However, models indicated that it was only ten times more difficult than deuterium-tritium. For it to work the laser pulse must be clean, that is, lasting only a million, millionth of a second. Optical energy is then converted to mechanical energy.

It is not commonly known but coal power stations actually emit radioactivity - it is a problem in Germany where they are considering burying polluted material. Producing energy by laser pulsing hydrogen-boron creates less radioactivity than using deuterium-tritium. Coal generation is very dirty compared to hydrogen-boron. The waste product is helium gas. Hydrogen-boron is also plentiful. Team leader Professor Hora say it could be some time before the research becomes reality.

High Blood Pressure Caused by Many Genetic Variants

It is now common knowledge that the propensity to get high blood pressure is genetic. A billion people in the world suffer from it. Persistent high blood pressure ultimately leads to heart disease and stroke.

The genetic work is complicated. Sixteen new genetic variations have been identified. These genetic factors can be counted: the greater the number people have the more likely they are to suffer from high blood pressure.

There are three kinds of genetic variants predisposing hypertension. One regulates blood pressure. Another affects pulse. The third type controls arterial pressure.

It appears that the modern diet has happened too fast for humans to stop the selection of these gene variants. Children are now suffering from this complaint. The variants will only be "selected-out" if these children do not reach child bearing age. This is a hard fact to accept, but this is the way natural selection works.

Radiation From Mobile Phones Is Dangerous

New evidence shows that mobile phones really are dangerous. Even the average user can suffer from brain damage, lower sperm count and altered DNA. Just 4 hours of continuous use will preempt the brain's capacity to repair itself.

When scientists originally said that pulsed digital signals from cell phones cause DNA breaks they were condemned for making it up. Now proof is very strong. Apparently, the industry has known about situational damage from mobile phone use for years. They have intentionally hidden the truth.

Research on insects shows that DNA fragmentation occurs in ovarian cells. Insects do have ovarian cells. This reduces the insects' capacity to breed. Long term exposure kills cells completely. Other work with rats shows bone damage to fetuses from just six minutes of radiation per day. And rats had memory loss. From this work it can be deduced that children are more at risk.
