power. No longer. In a “historic crossover‚” the costs of solar photovoltaic systems have declined to the point where they are lower than the rising projected costs of new nuclear plants‚ according to a paper published this month. “Solar photovoltaics have joined the ranks of lower-cost alternatives to new nuclear plants‚” John O. Blackburn‚ a professor of economics at Duke University‚ in North Carolina‚ and Sam Cunningham‚ a graduate student‚ wrote in the paper‚ “Solar and Nuclear Costs — The Historic

The Evolution of the Human Brain: How it Differs From Our Ancestors and Why? The human brain is a feat of evolution: it has allowed humans to have complex thoughts‚ conscience‚ build tools‚ create fires‚ and much more. Humans did not acquire this simply by chance. Evolution throughout our ancestral past has shaped and moulded the human mind to its state. The earliest of ancestors‚ including apes‚ had very small brains‚ but as evolution progressed‚ so too did the human brain. The rapid progression

Potential Energy • Definition and Mathematics of Work • Calculating the Amount of Work Done by Forces • Potential Energy • Kinetic Energy • Mechanical Energy • Power An object can store energy as the result of its position. For example‚ the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly‚ a drawn bow is able to store energy as the result of its position. When assuming

PLANT RESPONSES TROPISM is a biological phenomenon‚ indicating growth or turning movement of a biological organism‚ usually a plant‚ in response to an environmental stimulus. In tropisms‚ this response is dependent on the direction of the species. The word tropism comes from the Greek trope ("to turn" or "to change"). Tropisms are usually named for the stimulus involved and may be either positive (towards the stimulus) or negative (away from the stimulus). Phototropism is the growth response

Nuclear energy… Boon or Bane ? Nuclear energy? Nowadays these two words are always sticking on the society’s mouth‚ but do they know the actual meaning of it? Nuclear energy is basically defined as the energy released by the reaction within the nuclei‚ as in nuclear fission or fusion. The core reason of using nuclear energy is to generate electric power to satisfy human needs. Usage of the nuclear power plant as an energy generator came together with several boons and banes. As quoted by the

An Argumentative Essay “Use of Nuclear Energy: Safe or Not?” 23 Aug Most countries today are becoming more and more dependent on nuclear power as a source of energy because of its high energy output and the availability of uranium used for fuelling nuclear reactors that generate power to provide electricity in households. Although using nuclear power as a source of energy has benefits like this‚ the danger posed by using nuclear power is very eminent. This was demonstrated in the recent Fukushima

Plant Hemoglobin Hemoglobin is a protein-iron compound found within the red blood cells of most vertebrates and is responsible for the cell’s red pigment. These red blood cells carries oxygen from the lungs to the rest of the tissue cells throughout the rest of the body. Just as hemoglobin transports oxygen in humans‚ they have also been found transporting oxygen within plants. In plants‚ there are two types of hemoglobin that can be found; symbiotic and non symbiotic. Oxygen is used
