Writing Feedback / Speedy cannabis spit test could spot people driving while high [3]

Researcher from Stanford University, California developed new technology in detecting THC existence. THC is the active compound of cannabis or commonly known as weed or marijuana. The compound can be detected in saliva which is a viscous liquid within mouth.

Shan Wang's breakthrough technology using mobile device utilizes nanoparticle system that clasps THC molecules. Sensor will indicate THC from electromagnetic reaction of the components aftermath.

Several states in America have a differentiation about cannabis utilization regulation. There are twenty three states that allow weed for medical treatment and another four states for recreational use. In contrast, for driving regulation, there are disputable issues because the same concentration of THC has different effect for each person. There is no exact evidence of cannabis use causes bad driving habit. So that, more data are needed to deliver a conclusion accurately. But, Wang' idea of user-friendly system is a promise further of technology. "if it can be analyzed quickly and with known accuracy, and if that measurement can be correlated well with actual impairment, then you've got something quite useful.", the expert says.

Writing Feedback / Pandas Get to Know Their Wild Side - article from National Geographic [9]

Summarize article from nationalgeographic.com/magazine/2016/08/giant-pandas-wild-animals-national-parks/

China is where the popular bears are released the endangered animal to their habitat in August 2016. Giant panda population have declined and labeled endangered since 1990. So, it was a tough decision that China took to set them free into the wild, but it had been unprecedented success. The China still have to make sure this species survival in the conservation nature, are the population safe in the deep forest or just keep after them in the zoo facility.

DNA of pandas brings fact that they were transforming from carnivores to herbivores, but the reason and the exact timing is still unclear. It was called adaptation or animals changing behavior to suit the environment. In pandas, the adaptation happened in their teeth that transformed from canine teeth (identic to carnivores) to flat molar teeth (identic to herbivores) for the modern pandas.

Long time ago, panda used to live in China, Northern Myanmar, and Vietnam. But, researcher have counted there were just 2.500 species left in mountain of China on 1970s and plunged dramatically in 1980s because the lack of bamboo that was naturally die-off.
