Electrostimulation of the Brain Could Treat Elipepsy

It has been shown that elecrostimulation of one side of the brain can numb it and allow the other side, the creative part, to take over and temporally improve artistic skills. The sketching of animals by participants got much, much better.

There is hope that treatments for brain disorders will be discovered. A project by Australian and French researchers has applied sequential electromagnetic pulses (repetitive transcranial magnetic stimulation - or rTMS) to mice. Abnormal brain connections were corrected by this process.

Epilepsy, depression and tinnitus are caused by abnormal brain connections. Low-intensity repetitive transcranial magnetic stimulation (LI-rTMS) had a positive result on mice born with abnormal organization of the brain.

Permanent implants to human brains could improve life for many patients who have continuous episodes of brain maladies. The electrostimulation changes brain chemistry. A specific chemical spreads across large areas of the brain. It is this that corrects abnormality. Preexisting correct organization was not changed.

Aboriginal Subsistence Fires Benefit the Ecosystem

Bush fires are natural in Australia. Far from being a curse, they benefit the environment and wildlife generally. Of course this has to be qualified by houses being destroyed and injuries to people. Aboriginals have been intentionally lighting fires for thousands of years.

Actually, it has a positive impact on kangaroo evolution. A fire promotes an increase in kangaroo numbers. To get the greatest benefit the best time for a burn-off  can be identified. Human subsistence is crucial in managing this. It compliments the ecosystem.

Modern farming is detrimental to the way wildlife functions. The system is thrown off-balance. Stopping the burn-off and mono cropping changes everything. Australia needs more burning, not less. Authorities are following the wrong policy. Leaving native trees to grow tall can only lead to eventual disaster as a massive fire results as time passes.

Managed fires provide more food for animals as new shoots appear. Animals can also hide from predators in patches of older growth in the flatter landscape. It is only in farming areas that kangaroos increase to pest proportions. There is a natural peak in regions still controlled in the traditional way by Aboriginals.

Scientists Make Mice Transparent

Scientists have made mice transparent - let us hope they were dead first! Studying the human body and test animals in general is difficult because usually one has to carry out dissections to see inside.  The new process will change medicine.

Lipids block sunlight in bodies, so it has to be replaced with acrylamide which is just transparent hydrogel. After the acrylamide is absorbed, the bodies are placed into detergent which absorbs the lipids. Electricity is also applied to reduce the time taken to "clean" tissue.

The treated mice do not keep their original shape. They end up like gel in a plastic bag. Internal organs can be clearly seen, however. After staining, the structure of organs can be seen as shown in the picture above.

Micro-slicing has been used to date. A computer assembles a 3D structure for study. Both systems will probably be used in future as each as its benefits. There are plans to adapt the transparency technique to evaluate tissue in cancer patients. Biopsies will be treated to identify any cancerous cells.
