Fake Cat Mummy Puts Pressure on WA Museum

Anthropology: Cat mummy in Western Australian Museum a fake.
It is known that ancient Egyptians made counterfeit mummies, particularly of birds and cats who were given as offerings to the gods. In 1982 an X-ray of a cat mummy showed that it was a fake, probably made in the early 20th century. Staff of the Western Australia Museum who were custodians of the "mummy" were shocked and disappointed by the discovery.

A recent CT scan of the "mummy" highlights a human femur broken in the middle then molded to take the shape of a cat. The scan has been sent to Cairo for further study. To solve this problem once and for all a determination of its real age needs to be done. Why waste time looking and re-interpreting?  The WA Museum is still so ashamed of the issue that is has never released a photo of the fake cat mummy nor will show the X-ray or scan to the public.

Genuine mummies are on display today at the WA Museum with the Afterlife: Magic Mummies and Immortality in Ancient Egypt exhibition brought over from the British Museum. Let us hope that tests to verify age has been done on these ancient wrappings.

Ultrasound to Treat Alzheimer's Disease

A great deal of research is going on into solving the problem of Alzheimer's disease. It is a major issue with the number of elderly people increasing in most countries. Though young people can suffer from the illness it is perceived as a disease of the aged.
Ultrasound to treat Alzheimers disease
While most work has been done on the chemical and molecular structure of the brain, it seems that a simple treatment has been there all along. The University of Queensland has stumbled onto ultrasound as an effective treatment. First successful on mice, it is now being rolled out for humans.

Waves of ultrasound break up neurotoxic amyloid plaque. The cause of the illness is still there, but the damage done is reversed. Some old memories could still be lost. However, new ones will be kept. This will reduce the need for resources in caring for the elderly who will able to function on their own.

In tests, mice were capable of solving problems that had beaten them before. Decision making is the most important function of the human brain apart from those keeping a person alive. Long term memories are not so critical: though ideally, one would not want to loose these.

It is debated whether the use of ultrasound would improve executive functions of healthy brains. Other diseases also damage the brain and detection of them is difficult. In the future we could all be getting regular ultrasound.
