Scientists have developed a stem cell gel that can help heal traumatic brain injuries. The gel was created by Dr. Ning Zhang at Clemson University and is injected into the site of injury, where it can stimulate biological processes. It has been shown to treat injuries from car accidents, falls, and gunshot wounds. When news of the gel was reported in 2009 on the PopSci website, it received a largely positive response from readers, many of whom saw it as an advancement in medicine. However, some comments acknowledged that scientists need to ensure the gel only promotes healing and not unwanted growth like tumors.

Scientists have developed a gel out of stem cells which helps the brain to recover from
‘traumatic injuries. It is said by scientists that this gel can treat head injuries which have
been caused by many things for example car accidents, falls and even gunshot wounds
The gel was developed by a scientist named Dr Ning Zhang at Clemson University in
South Carolina. The gel is injected at the site of the injury and can also be used for
different biological processes by adding different chemicals for stimulation.
This article was from a website called popsci-http://

On this website there are many different articles posted.
This website has many comments from different people on this topic many being
positive. The public perceptions change depending on the topic, whether it has an
negative impact on them or positive.
This topic being a positive one had a positive public response, many people have
commented saying how having this type of a gel is a new chapter to medicine. Everyone
is different and have their own opinions regarding this matter as some people will think
much more deeper for example on the website i have already mentioned 1 person has
said how the scientists have to be careful that this gel only promotes healing and not the
growth of the type of things like tumors.The members of the public has thought very
deeply and has suggested that there has to be a balance.
Overall This article was known well in 2009 as it had a good response back from the
public and also the media spread the news from a positive side of view however this is
not the case when something to do with the government comes up where the media will
add and take parts away to make their report more interesting and out the whole
concept in a negative side.

2. The other thing that really changes how the public perceives is the age group of the
public. For example the younger group of people will relate better to blogs that have
been posted on social networking sites like facebook. On the other hand the older
generation will have a better response to news reports and newspapers.
