Chemists Devise Self-Assembling 'Organic Wires'

Scientists have created a pacemaker made of carbon-based compounds. These wires are softer than the original metal ones and are ultimatley more comfortable for the patient recieving one. They are also smaller, which makes them easier to adapt to.

I think this is a great invention because the original pacemakers that were placed in people seemed uncomfortable. My grandfather had to get a valve replaced in his heart some time ago and I was told that it was made from porceiln. When I would listen to his heartbeat it sounded as thought there was a clock in his chest, ticking. I think if scientists can come up with this alternative for the metal wires, they should now try and work on finding new materials to use that would help people who have to get parts of thier hearts replaced. Otherwise, this was quite an interesting article.

WSU researchers have found the key part in the brain that triggers sleep. There is a specific substance in the brain that drive sleep.This substance makes chemical transmitters in the brain that takes the brane from awake to asleep.This research has potential to help victims of strokes or other brain injuries. Krueger said, one of the researchers, While this discovery is exciting, there is still a lot to learn.
I think that any research that has been found to help victums with brain injuries is something great. Also the findings help victums with strokes. Krueger said there is a lot to be learned, but what we do know and what we have learned is going to change someons life.

In the article " Men with bladder exstrophy report robust sex lives, but women fare worse, Hopkins study shows", it explains that men have more robust sex lives than women if their bladder is formed on the outside of their abdomen. This is called bladder extrophy and requires surgeries from when the patient is born. Two thirds of women with this condition report to be dissatisfied with their sex lives. However, only thirty six percent of men are not moderately or very satisfied. Falling of the uterus, which is called prolapse, is a common complication during surgery to cure this condition.
In my opinion this article was very intersesting. I would have never guessed that men with bladder exstrophy have more robust sex lives than women would with the same condition. In this article it explains that men will have more robust sex lives if the bladder is formed on the outside of the abdomen. I wonder how they proved that and i also wonder why that is. With modern day technology there is so much to be explored!

This article talks about how women who are living with HIV can take treatment to help protect their baby from getting HIV. Five years ago there was a therapy that women could get to help the transmission, but most women don't even know that they are living with HIV. Even though this is a new drug, only 15% of women can actually recieve this drug. Each country is trying harder and harder to help the women who are living with HIV. In some countries over 80% of women have been helped to fight from giving this to the unborn child.

My opinion on this article that it is a great way to help mother's and their babies. I think that a baby should get the same chance to have a healthy lifestyle as anyone else should get. I wish that there was someway that all women who are living with HIV could get some kind of treatment to decrease the risk of spreading this to their baby. But before some women who don't even know that thay do have HIV, it is to late to help their unborn baby. I believe that if the mother does know that she is at risk of passing HIV on to their baby then the drug is comethng that should be strongly consider to help the life of their baby.

The human skeletal system is a bodily system that functions as a framework which gives proper shape and protection to both the external and internal parts of the human body. The human skeletal system has six major functions in human anatomy including functions of support, movement, protection, blood cell production, storage and endocrine regulation. Basically, joints are classified structurally and functionally. Structural classification categorizes the joint based on how it connects the bones in the human skeletal system. On the other hand, functional classification is determined by the function which the joint serves.





There are fibrous joints that are connected by dense connective tissue composed of chondrocytes, a type of cell which produces collagen and fibers. there is also Synovial joints. they are the most mobile and movable among the three structural classification of the joints. there are seven Synovial joints present in the human skeletal system. In addition to the structural classification of joints their are the functional classification. Note that all synarthrosis joints are not fibrous.

Multi-resistant skin bacteria spreading in bacteria

http://www.biologynews.net/archives/2010/09/08/multiresistant_skin_bacteria_spreading_in_hospitals.html

In this article there has been a skin bacteria that has developed to different antibiotics. These different types of antibiotics can cause intractable infections . The infections seem to be spreading in the hospital in Sweden. The skin bacteria is Coagulase-negative staphylococci is bacteria that belongs to the protective bacteria flora on the skin. Staphylococcus epidermis is a common cause of care-related infections. Some of these infections are are sometimes difficult to treat. Some antibiotics and hygiene routines do not prevent these strains from getting a foothold in hospital. This is a cause of urinary tract infections that young and middle-aged women contract outside the hospital environment.

My opinion about this article is that should try harder to make more antibiotics that can cure this infection. The hospitals should try to infect it around so that these contagious infections wont keep spreading around. There needs to be something to stop this infection or else it will spread through out other countries.

Why the craving for cocaine won't go away
http://www.biologynews.net/archives/2010/09/17/why_the_craving_for_cocaine_wont_go_away.html

Why People that have used cocaine are in great risk of becoming addicted, even after being clean for some time. Drugs such as crack/cocaine are addictive because they "hijack" the brain's reward system. The "hijacking" is long-lived and sometimes relapses into abuse, when the person gets exposed to stimuli in surroundings that are associated with the drug.

With this reasearch I have just read, I am beginning to understand why people have hard times coping with quitting. I believe the best thing to do is just to stay drug free and not trying things just to get "high."
