A new study, published in the journal BioScience, claims that over 1,500 species of flora and fauna would be eradicated if this wall is erected. To date, nearly 2,800 scientists have signed a petition stating that this sort of environmental destruction ...

How Laws to Protect Biodiversity Backfired on Scientists Trying to Save It - The Wire


The Wire
The legal fences around biodiversity research are so strong that it even thwarts basic research and international collaborations. The remedy, the signatories have argued, is a separate agreement to ensure fewer restrictions on academic research.

The cardiovascular, or circulatory, system is a closed elastic circuit consisting of the heart, blood vessels (arteries, capillaries and veins) and the blood. The primary function is to pump oxygenated blood to the tissues throughout the body and reabsorb waste carbon dioxide for its removal. This function is performed by the use of pulmonary and systemic circulation.

Signal transduction (also known as cell signaling) is the transmission of molecular signals from a cell's exterior to its interior. Signals received by cells must be transmitted effectively into the cell to ensure an appropriate response. This step is initiated by cell-surface receptors.

Cell Cycle - Tocris Bioscience
United Kingdom

The cell cycle is the regulatory network that controls the order and timing of cellular proliferation events. It is divided into four stages, G1-S-G2-M. The G1 and G2 stages stands for 'GAP 1' and 'GAP 2' respectively. The S stage stands for 'Synthesis' and is the stage when DNA replication occurs. The M stage stands for 'mitosis', and is when nuclear and cytoplasmic division occurs, halving the genome.

Your heart is one of the most hard working of all organs in your body and so is your your circulatory system, which is literally a "highway" for nutrients and gases which are continually transported back and forth throughout your body. This system is often the one which has the ability to cause you an incredible amount or grief as you age, and is reflected particularly in the high rates of circulatory disorders such as stroke and heart attack.

Cardiovascular diseases are a major cause of mortality in the developed world. In New Zealand (NZ), they are the leading cause of death and result in over 40% of all deaths. These diseases result in a net hospitalisation and medication cost in excess of $935 million p. a. The impact of these diseases on NZ is demonstrated by the fact that five out of the thirteen principal objectives of the NZ Health Strategy can be related to the reduction of

United States

The heart is a muscular pumping organ located medial to the lungs along the bodys midline in the thoracic region. The bottom tip of the heart, known as its apex, is turned to the left, so that about 2/3 of the heart is located on the bodys left side with the other 1/3 on right. The top of the heart, known as the hearts base, connects to the great blood vessels of the body: the aorta, vena cava, pulmonary trunk, and pulmonary veins.

Cardiovascular System Function
United States

The functions of the cardiovascular system is considered to be one of the most important functions of the human body. Knowing about the functions and structure will help you a great deal in keeping it healthy for it to function appropriately. Its functions can be categorized into three main domains: transport, regulation and protection. The organs of the system carry out these functions in coordination with the functions of the other systems f

Becomehealthynow.com - The Cardiovascular System
United States

The cardiovascular system is made up of the heart and all of the blood and lymphatic vessels in the body. The heart acts as a pump to drive the blood; a complex fluid made up of digested food materials, respiratory gasses (oxygen being carried in, carbon dioxide being carried out), and protective and regulatory chemicals through the approximately 60,000 miles of vessels in the body. More than 90 percent of Americans live in jeopardy of having

Cardiovascular System - Mananatomy

Cardiovascular system means the system of heart and blood vessels of human body. The term cardiovascular is a combination of two word Cardio and vascular. The term cardio is derived from cardiac meaning Heart and the term vascular means blood vessels. So the name itself indicates that cardiovascular systems is the system of heart and blood vessels. Cardiovascular system is also known as Circulatory System.
