Nuclear Physics to Track Australian Waterbirds

Nuclear physics used to track Australian waterbirds.
Australia's native birds are on the decline - those damn humans! Yes, we are destroying the planet and we have to do something about it.  Obtaining data on bird numbers is paramount. Nuclear physics is the answer.  Researchers are examining feathers recently dropped by waterbirds. It provides information on where birds have been and what they have eaten.  The I-TRAX Core Scanner shows chemical changes over time. A mass spectrometer is also used to determine oxygen, hydrogen and nitrogen isotopes.

Feathers are composed of keratin like hair. Water sources have different chemical composition. This is stored in the keratin, so a map can be created of where birds have been living. The method of feather analysis is much cheaper than leg banding or satellite tracking.

Members of the public can contribute. At present scientists are picking up feathers then posting them to the Australian Nuclear Science and Technology Organisation (ANSTO). Anyone can do this to further the body of data on birds.

Energy Use Due to Mobile Phones Is Unstainable

There is an energy crisis slowly creeping up on us. We go about our daily business enjoying the benefits of computer advances while not realizing that massive amounts of energy are being consumed.

Mobile phones are designed with very little hard storage. Reliance on cloud services is increasing at a rapid pace. Many developing countries do not enjoy continuous energy supplies. When the electricity goes off so does cloud storage. In advanced countries aluminium producers were blamed for eating up too much power, now everyone is responsible.

A new study, The Power of Wireless Cloud, clearly shows that the continuing use of electricity is not sustainable. Energy use by cloud services will be equivalent to 4.9 million cars over the period 2012-2015. This is known by comparing energy from petrol to power station input.

It is not just the cloud. Wi-Fi will use more power than anything else. Computing networks are not "clean". Many do not consider that most electricity is still being produced with dirty energy inputs. Even nuclear is dirty - it contaminates.

New Laser Processing of Uranium Is a Danger

The last thing the world needs is an easier way to enrich uranium. There is nowhere to put the used uranium and the disaster in Japan shows the potential risk and damage from nuclear power stations.

A new laser enrichment process has been developed by General Electric. It enables production of enriched uranium cheaper, quicker and in larger amounts. It is feared that "rogue" states will get hold of the knowledge and make uranium for nuclear bombs.

Claiming that nuclear power is a way of reducing greenhouse gases is ridiculous. If more power plants are built more will be at risk from natural disasters. Vast tracts of land will be left uninhabitable as in Japan. It is ironic that GE has made this leap forward in partnerships with a Japanese company, Hitachi.

They are talking now about turning the damaged power plant back on because the country cannot manage without it. Workers there will have to wear full-protection suits all day every day to generate electricity.

Don't Get Excited About Nuclear Power

The world is in a tight corner and people are far too optimistic. Thinking that carbon pollution will cure itself is not scientific fact. Only a fool would hang onto the notion that nothing is wrong. The poles are thawing out and that is fact. Polar bears are dwindling in number as their traditional frozen feeding grounds get warmer. Butterflies that used to stay on in winter in southern England have moved north to colder climes. Those species that stay are getting larger.

Despite coal power stations being the main culprit more are being built to meet Mankind's increasing demand. Much is said about nuclear power stations holding the key to a "clean" future. Used uranium is going around Europe at this very moment without finding a home in any country. Where will this dangerous product be put in the future? Unless it is blasted into space toward the sun there is no where for it to go. France gets more than 80 percent of its electric power from nuclear means, but this is the country with the used uranium problem.

Even some scientists say the carbon footprint of nuclear power will be reduced to zero. This is hogwash. If you ignore nuclear waste everything looks good. Include it and it all looks very bad indeed. Nuclear power isn't cheap. Building a nuclear power plant requires long term planning. Safe guards are costly. Their useful life is also limited. Coal plants can stay in operation for much longer.

Within twenty years all 25 of China's new nuclear plants will come online. The world will be a militants' paradise with used uranium for sale on the open market. The consequences will be catastrophic. Saying there is no carbon price is absolute rubbish. If a bomb goes off there will be plenty of pollution.
