Newly Identified Stem Cell Raises Hopes for Treatment

There seems to be a scientific breakthrough every minute. You go onto the Internet and a new claim appears. Some of course is recycled old news. However, new discoveries are made all the time. Despite spending cutbacks in some countries, science seems to be leaping ahead.

You would think that just about everything is known about the body. Nevertheless, a new stem has been found. A four continent research enterprise called Project Grandiose has identified the new cell which has been put into the "F-class": the cell has a fuzzy body when viewed on a microscope.

It is hoped that the cell can be used in the treatment of injuries and illnesses. The days of using stem cells from afterbirth material are long gone. Adult cells can now be modified for treating various health problems, but this is early research. The only successful treatment to date is for macular degeneration.

Targeting modified stem cells is the main problem. They are like tumours and in the wrong place they can cause damage. The new cell indicates that it could treat diabetes. Producing them on a large scale is the next big issue for the third class of pluripotent cells yet discovered.

Drone Lands on Athlete - Injuries

Companies are announcing delivery of parcels and takeaway food by drone. This is all advertising bling. It cannot possibly happen. Strict aviation rules will apply and this will completely rule them out. They are too dangerous. Imagine one landing on a crowd of people. Its rotors would cut flesh everywhere.

At the moment there is no restriction on their use in most countries because not many are in use. As accidents happen there will be strong calls for limitations on who can fly them. An athlete in an Australian triathlon was hit by a drone carrying a camera. She suffered lacerations to her
head. The owners of the drone said he was not hurt. In other words they denied responsibility. The first thing that must be implemented is insurance for these "flying attack vehicles". Wire protectors covering the rotors is another option. Part of a propeller was stuck in the runners head. To say she was making up her injuries is rubbish - she had three stitches.

The owner of the machine said that the drone had been hacked. This is not possible as few knew a drone with a camera was going to cover the event. Another problem is the question of licencing. The person flying the drone had a licence but the company who hired him did not. This is a gray area in the law. Oddly, the controller held a plane flying licence which does not cover drones.

CASA the official aviation authority is investigating the incident. Apparently many drones have crashed with few being reported. They are powerful machines and can quickly leave a controllers line of sight. Accurate landing software does not exist. A GPS or radar type landing system is absolutely necessary as soon as possible. Until this is done all drones should be banned from highly populated areas.

Cat in New Zealand Falls Five Stories and Walks Away

A New Zealand cat falls from a great height and lives!

Alison and Graham Pike live a quite life in an apartment on Auckland's viaduct. They had no idea that their tabby cat, Camo, would become a celebrity. Spending life on an apartment balcony can be quite dangerous. One small slip and you fall a very long way.  And Camo did fall.

It is not actually a free-fall from the balcony - there are things in the way to block the fall. The cat either jumped onto the glass balustrade then fell on to the tarseal, or ducked under the balustrade then slid off and fell further. A balcony lower down sticks out more than the fifth level balcony so the cat would have bounced off that before finally landing at ground level. In all it must have been like an obstacle course for the cat.

Well, the outcome was a broken jaw and three broken teeth. Mr and Mrs Pike were informed by security staff that their cat was under the restaurant sofa and its mouth was bleeding.

The cat has learned something though - It doesn't go out on the balustrade anymore. You see it is new to this way of living. The couple only moved into the apartment with their cat 15 months ago. Living high up is much different than living at ground level.

Gene Therapy on the Brain Dangerously Changes Neuron Structure

Gene therapy for brain injuries and illnesses may be a good thing, but this treatment changes the shape of brain cells. Researchers in Western Australia say there is nothing to worry about because damaged brain cells regenerate or live longer. They say this when there is no proof that in the long term everything will be alright.

They say it is wonderful how brains cells function better after nine months of treatment. Apparently, the neurons become round due to new growth-promoting genes that stimulate them. The fact that surrounding genes away from the treatment area also change is in my opinion something to worry about. Obviously, when this occurs it cannot be reversed.

Doctors admit that the way neurons deal with information after treatment is never the same again. Furthermore, they suspect that the long-term effects may not be beneficial to the patient. It is a good thing that researchers are looking for a way to stop gene therapy in its tracks if anything goes wrong.
