When I went outdoors with my laptop, the most annoying thing is brining alone the bulgy charger alone. I was thinking if there is any way charging the laptop battery without carrying the annoying charger around. One of the solution I thought was solar power (when you went outdoors during the day time). This is my drawing of USB Solar Charger. I’m not Macs, and I don’t know photoshop. All pictures were drawn with windows paint.

This usb laptop charger can be rotated to capture sunlight (just like the way of using the old microscope). USB is my choice but not the power chord.

Another solution I thought was using mouse as power generator. Most of the time when I was using laptop, my hand doesn’t left the mouse (unless I am typing). I was thinking if it is possible to use mouse/keyboards as laptop power generator.

Above are just random thoughts.

I watched “100 Greatest Discoveries: Genetics”, which was one of the three DVDs I bought from China.

1. Laws of inheritance.
2. Genes are located on chromosome.
3. Genes control biochemical events.
4. Transposon.
5. DNA carries genetics material.
6. The double helix.
7. Messenger RNA.
8. The genetic code. (codon)
9. Restriction enzymes.
10. RNA alternative splicing.
11. Minisattelite DNA.
12. RNA interference.
13. Human Genome.

From the documentary, I realized that there are a lot of female scientists not being recognized in their own field by the male scientists, namely Barbara McClintock.

Monash University

A Monash University PhD student has developed a new technique that could revolutionise stem cell treatment for Parkinson’s disease and spinal cord injury.

David Nisbet from Monash University’s Department of Materials Engineering has used existing polymer-based biodegradable fibres, 100 times smaller than a human hair, and re-engineered them to create a unique 3-D scaffold that could potentially allow stem cells to repair damaged nerves in the human body more quickly and effectively.

Malaysia Government banned its people to play firecrackers since ages ago, but there are still a lot of people bought in expensive firecrackers to play them during Chinese New Year.  Some people scare their children harm by the firecrackers, and some of them would like to have the atmosphere of noisy sound during the Chinese New Year., so fake firecrackers like this are sold.
