The hope of genetic treatment may be scuttled as it is becoming known that we have good and bad genes but their behavior depends on whether they are turned on or off. Apparently this changes throughout the day let alone over the years. A new endeavor to study diabetes and diet could also be a waste of time. Even sufferers know that diabetes type 2 is caused by eating the wrong food. However, few people will change their lifestyle. A genetic predisposition could add to this. Yet, with the number of medications taken today the link between long term prescription use, genetics and food is a hard nut to crack. Including a third factor makes understanding the issue much more difficult. As always, research will be done on mice for the genetic/food duo. Unfortunately, mice may be mammals, but they ain't human. Finding a cure for diabetes 2 is way down the track. Scientists will be messing around in the lab collecting data on mice for at least 10 years. ◆ Genetics ...

An old joke: Do you want a new heart? Then get one from a gorilla - "grunt!" This is not a joke any longer. Australia has just given the go ahead for animal-to-human transplants. This is a turn around from the outright banning of such transplants in 2004. There are two conditions: one, a monitoring system must be in place: and two, there must be a patient register. New Zealand allowed transplants in 2005. The first "transplant" involved implanting insulin producing pig cells into volunteer diabetics. This change has happened when direct research on animals such as chimpanzees is being reduced because tests can more effectively be done in a test tube. Results in many instances are quite different for chimpanzees, for example. This was discovered in AIDs research when chimpanzees didn't get AIDs. They became carriers of the disease. Animals are proving more useful when material at a cellular level is transplanted. Using animals as hosts is far more beneficial ...

Major medical advances are a long time coming. Development of a reliable blood sugar level monitoring method for type 1 diabetes is a case in point. It has been claimed as a revolutionary achievement. It consists of a monitor connected to an insulin pump. With all the money being poured into research this should have been done years ago. Heart surgery hasn't moved much further forward than the first transplant in South Africa decades ago. Stents are still the primary treatment. The number of heart transplant recipients remains very small indeed. Artificial hearts are still not safe enough for general use. Cancer shrinking techniques have been identified but they have not been perfected. DNA treatment is a long way down the track. Much hope had been raise over stem cell research. This has slowed right down. Surgical "tricks' have been done in one-off procedures. Getting them into general hospital systems is not happening though. Drug companies are pushing very expensive med...
