The core of the hepatitis B virus is generally in the shape of an icosahedron. Within the virus, there are two strands of DNA, one smaller than the other, which is circular. HBV is around 42 nm in width, and the core is surrounded in a 4nm thick coat. They are enveloped, which means they are more susceptible to being destroyed, because the envelope is very thin. Viruses in general are very small, much smaller than bacteria, and HBV is no different. (Image:…

Organ Allocation is a field of bioethics that is always at great debate and consistently being updated in accordance to new information obtained through daily research. The decisions brought forth to those in deciding organizations are expansive and ethically thought-provoking. The list is heavily sided to those in need versus those that give. Ethical treatment of the organs is of the upmost urgency. These are noted as lifesaving elements and should be treated justly and with reverence. Those in…

This island has to be saved for its trees, it has to be saved for its animals it is a part of a reserve forest, it belongs to a project to save tigers, which is paid for by people from all around the world….who love animals so much that they are willing to kill us for them…this whole world has become a place for animals, and our fault, our crime was that we were just human beings, trying to live as human beings always have, from the water and the soil.

Animals are born with natural instincts that kick in at a very young age. If an animal is raised in a zoo it may not know what to do when released into the wild. These animals may not be able to survive. So which is best for the animals, the wild or the zoo? Honestly, I believe animals should live in the wild. When an animal is born in captivity their natural instincts may not kick in. These animals are raised without the fear of predators, the instinct to hunt, or even to be on their own. Once…

Captive breeding and reintroduction programs are important tools for the establishment of threatened animal populations, but experimental approaches require to compare the outcomes of these programs that will increase post-release survival. The Kaiser’s Mountain Newt, Neurergus kaiseri is listed as a vulnerable by IUCN criteria, to aid about the ecology and the conservation of this species, we carried out a trial release of 20 newts reared in captivity on 4 occasions during the spring and summer…

mental deterioration. This is why animals in zoos are seen playing with toys or sometimes hunting their meal (Horton). These activities can help to stimulate brain growth, which, in turn, leads the animal to a healthier, happier life. Once again, the in-situ research that zoos conduct proves valuable; the researchers can learn what activities the animals do in the wild and recreate them to the best of their abilities. Zookeepers have also proven extremely valuable to animals’ health because they…

Have you ever been to a zoo? Zoos are very popular and everyone has been to at least one, at some point in their life. They are known for showing off the wild animals, and educating you on them at the same time. I don’t think zoos do very well with that. To me, a zoo is a large business that captures wild animals and changes their lives forever. They hold them in captivity and don’t treat them like the should, like wild animals. Many zoos are businesses and known for only caring about the money,…

Shenandoah National Park Home to many of nature’s wonders, Shenandoah National Park is known for its varied species of animals to their amazing landscape. Located in Virginia, the park’s towering mountains, was partly formed by the Appalachian mountain range, known as the Blue Ridge Mountains. On one side of the mountains, the vast forest and lush valleys border the Blue Ridge mountains. Formed by the clashing of tectonic plates billions of years ago, the mountain range now houses the…

The long, spotted neck of a giraffe gracefully swooped down to the biscuit I nervously held in the air. I have never felt more humbled to stand before such a grandiose animal, nor more present in and aware of the fascinations of nature. Historically, zoos have come a long way from entertainment facilities to conservations education centers designed to inspire its audiences. Yet, they have always been controversial even until this day. According to architect and zoo director David Hancocks,…

Imagine being in a cage your entire life, locked up in a confined area with people condoning you to a lifetime of of being used as a source of entertainment. The only view an animal in captivity will ever experience, is life behind metal bars and barren concrete with people gawking at them. The number of animals suffering from extreme stress and depression is increasing daily. Zoos teach people it is acceptable to interfere with animals in their natural habitat and continue to place them into…
