Should evolution be taught as an accepted theory in American public education or is there a controversy that needs to be taught? This question has been one that has been fought over and in courtrooms and debated over in the public opinion for decades, with many precedents being set over how to set and enforce guidelines as to not infringe upon the rights of specific groups within the country.
Evolution is all of the cumulative changes that happen in a population over time. These changes are then produced at a genetic level as organisms’ genes mutate and/or recombine in different ways during reproduction and are passed onto future generations. This process is important because it allows species to adapt to certain areas in the world and survive better with those adaptations that had to have taken place over time. Oftentimes evolution and natural selection get mixed up. Natural selection is a part of evolution but is not a whole theory. Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations exists within all populations of organisms.
An HIV patient has undergone stem cell transplantation with a donor possessing an HIV resistant gene, and the patient has shown no signs of the HIV virus since the procedure. Scientists tested the patient 30 months after completing treatment, and the virus seems to be obsolete. The patient, who is from London, is believed to have been cured from HIV, and although remnants of the HIV virus remain in the patient’s tissue samples, it is no longer active and are considered fossils. This extraordinary breakthrough is believed to be the second case of HIV being cured in a person. With advancing medical technologies, we are able to see the effect on those who used to be believed to have to live with their condition forever.
Plants need sunlight for photosynthesis, but sometimes too much sunlight can interfere with the process of photosynthesis. The sunlight is used as energy for the plant in photosynthesis where the light will go into the light reactions and eventually into the calvin cycle as we have learned in class. Photosynthesis allows plants to store solar energy as sugar molecules, but too much sun can dehydrate and damage their leaves.
The ability to grow human-derived blood vessels in a pig was recently proved with a new approach that has the potential for providing unlimited human vessels for transplant purposes by researchers at the University of Minnesota Medical School, an innovative graduate school that is at the forefront of learning and transforming medical care and educating the next generation of physicians.
“Coronavirus,” a word we have heard a multitude of times over the past three months. It has caused global panic which has led to schools and offices banning in-person contact, items flying off of the shelves in stores, and people buying large quantities of masks. The World Health Organization declared it a pandemic just a few days ago, and highlighted various points to help with the prevention of COVID-19. As the number of cases around the globe rapidly grows, there is a push for understanding how the virus “hijacks” one’s cells and developing a vaccine.
The call of the Red-winged Blackbird is a familiar sound of the wetlands.
All living organisms consist of carriers of genetic information called DNA. These molecules are responsible for carrying genetic instructions regarding the development and function of living creatures, and sometimes DNA is damaged, resulting in the altering of that genetic message, known as a mutation. These changes can be interpreted as harmful or beneficial occurrences depending on the situation. For instance, mutations can be considered beneficial when it comes to creating new versions of proteins that could help an individual adapt to changes in their environment, which in turn, is essential to the process of evolution. On the other hand, mutations may alter a protein that is crucial in the normal development of an individual or cause a medical condition or genetic disorder. In order for researchers to gain a better understanding of how to treat or prevent specific genetic disorders, it is important that they are able to identify the mutated DNA to blame.
