    Title:Transplanted brain stem cells survive without anti-rejection drugs in mice

    Article Summary:
    At John Hopkins University, scientists may have discovered how to repair the damaged brain using stem cells. An experiment was tested on mice, to see if it was possible to transplant certain protective brain cells into the brain without the use of lifelong anti-rejection drugs. As of now, anti-rejection drugs are used to fend of tissue rejection, but leave patients vulnerable to many side effects. Patients would have to take the drugs lifelong to protect themselves from harmful side effects. In the experiment, scientists used glial cells which produce a protection for the neurons of the brain, which were genetically engineered to glow so that they could be kept track of. The scientists transplanted the glial cells into three types of mice: mice that were genetically modified to not produce a cover for the neurons, normal mice, and mice bred to not be able to mount an immune response. The scientists then used antibodies that had the ability to block an immune response, which they stopped after six days. Using specialized cameras, scientists tracked the glowing cells in the mouse brains looking for glial cells, or their absence. The results of the test showed that mice who received the antibody treatment maintained significant levels of glial cells while the ones who did not didn’t. The result showed that cells could survive the transplant and was a success.

    Personal Reaction:
    I believe that this is a great success for the world of science because we may be able to transplant stem cells into kids born with disabilities. I chose this article because my neighbor is actually having stem cell treatments as of now. His behavior has improved drastically since the treatment started, and it appears to be working. The ability to transplant stem cells may change the lives of many around the world.

    Title: Fruit Flies Live Longer with Combination Drug Treatment

    Article Summary:
    In a study led by UCL (University College London) a triple drug combination has been tested that can extend the lifespan of fruit flies by 48%. The three drugs used in the treatment were lithium as a mood stabilizer, trametinib as a cancer treatment, and rapamycin as an immune system regulator. The findings suggested that the treatment has the potential to be used for age related diseases. The experiment found that the combination drug treatment may be used to target the cellular systems of the body, slowing down the ageing process. The three drugs combined each acted on different cellular signaling pathways that formed the nutrient sensing network. The network in the human body adjusts the response to changes in nutrient levels. Scientists hope to countinue testing and improving the drug so that they may move along to animal testing and hopefully human trials.

    Personal Reaction:
    After reading the article I realized the treatment, if able to work on humans, will be a great step forward in science. The treatment has the ability to give many elderly a longer lifespan. As our scientific knowledge increases, our ability to affect our world becomes greater, and we as humans are able to grow. I realized that science is one of the main reasons the human race is able to survive and grow over time.

    Title:Mechanisms of real-time speech interpretation in the human brain revealed

    Article:
    In a recent study, it appears that researchers from the University of Cambridge have come a step closer to figuring out how we as humans, are able to understand a spoken language so quickly. The ability to rapidly process the languages involves a large complex set of computations in the brain. Researchers at Cambridge University would say that are ability to put words into context is credited to the best computer we’ve ever known, our brain. Researchers believe that we haven’t been able to replicate the brain into a computer because of how poorly we understand it. The study focused on the Semantic Composition, which is the central understanding of the speech process. The study conducted showed the process in the brain, when a test group of people were given a sentence. Scientists were able to track the brain networks and signals, which revealed how the brain responds and breaks down a language. Researchers found that our brain uses a mathematical system of probability and interprets the next word in a sentence according to the previous words in the span of milliseconds.

    Personal Reaction:
    I never thought about the process of how we understand language so quickly. I didn’t realize that my brain is a computer that has the ability to process tons of information in so little time. After reading the article, I realized that if scientists were able to fully understand the brain, then so much in our world would change. As of now researchers around the world are working to develop a brain in a robot, known as A.I. If researchers understood the complexity of the brain, they could input the information into computers and robots, making them more intelligent than ever before.

    Title: Children told lies by parents subsequently lie more as adults, face adjustment difficulty

    Article:
    A recent study through Nanyang Technological University gives scientists the belief that lies told by parents to their children’s may affect the children later on in their lives. Effects may include psychological and social challenges, disruptiveness, conduct problems, experience of guilt and shame, as well as selfish and manipulative characteristics. The study conducted took 379 young Singaporean adults and asked them four online questionnaires. The questions focused on times when the young adults parents had lied to them subtly of dramatically, and if as of now they had any psychological or social challenges. Many people who were lied to during their childhood would admit that they had social or psychological issues one way or the other. The study showed researchers that parenting by lying could place children at a greater risk of social development problems. Researchers concluded that the types of parenting where the parent lies to their children to show authority often result in harming the children as they grow older. The article was published with the goal that parents would understand the risk of lying to their children even if it may be subtle.

    Personal Reaction:
    It never occured to me until now how easy and often a parent may lie to get their way or simply get their child to stop or do something. It is very common in our culture to lie, and that is why it seems ordinary, and goes unnoticed. I did not realize that simple lies like, “If you don’t come with me now, I’ll leave you by yourself,” could affect my behaviors as I grow older. The article is able to give insight to a major flaw in our everyday lives that goes by unnoticed, and perceived as normal.

    Title: Nepal is reeling from an unprecedented dengue outbreak

    Article:
    The country of Nepal is reeling from the Dengue outbreak, and has recorded at least 9,000 cases of the disease. The outbreak is due to climate change, which attracts disease carrying mosquitoes. When the outbreak struck regions across Asian tropics, Nepal had nothing to fear due to the chilly Himilayan climate. Unfortunately, climate change would allow mosquitoes to enter Nepal infecting thousands across the region. The Nepal government was shocked at the situation, stating they had never had any outbreak like the one they are facing now. The viral disease is carried through a specific type of mosquito, associated with warmer climates. The epidemic as of now is spread out through many regions, killing roughly over 20,000 people a year, and infecting much more. A vaccine has been developed for the disease, but no cure. Due to climate change many of these mosquitoes are entering different regions across the world, posing a threat to millions.

    Personal Reaction:
    The threat that the Dengue outbreak poses too everyone around the world is severe. The epidemic’s spread is due to climate change. If nothing is done about climate change, the virus spreading mosquitoes could affect an extremely large amount of the population in our world. The threat that the outbreak poses is extremely serious, and puts us all at risk. Scientists predict that by 2050, even the United States will be suitable for Dengue transmission. This article is able to uncover the epidemic that is spreading throughout our world.
