How Do Fuel Cells Work

Fuel Cells are important emerging technologies today and have the potential to successfully replace the currently employed fossil fuels, towards a cleaner, greener, more efficient and more capable source of energy. They have the potential to generate power to run automobiles and hence replace the ubiquitous Internal Combustion engine and also provide for the running of stand-alone and portable power generation units which need mechanical input. As a principle, Fuel Cells operate just like a battery... Read more »

Making Haste with Waste

One of the major sources of biomass is waste, in all its organic form and splendor. Our society has away of producing tons and tons of waste in all possible forms and anything organic in that waste tumbling out of our garbage bags. Biogas is important simply because we are out to set this waste into something remarkably important like energy, power or heat. Getting something out of nothing magnified a million times and being put a price on. For instance, the Australian economy has a good start with... Read more »

Function of Enzymes as Biological Catalysts

What’s so crucial about enzymes? Are they life-sustaining unit of the living organism? No, yet they can’t be ignored from life’s existence. As long as life is present on earth, the enzymes will retain their importance. Enzymes are basically proteins existing in chain-like structure in the form of amino acids. And in the body cells of organisms, enzymes play the role of biological catalysts to cater or progress a particular reaction taking place over there. This is the key area of... Read more »

How is Enzyme Action Regulated in a Body Cell

It’s very interesting. On one hand you know enzymes function as catalysts. So they are responsible for regulating and controlling any chemical reaction. But doesn’t this strike to your mind whether something is required to regulate the enzymatic actions as well? Of course, a control mechanism is also set to operate the activities of enzymes. Exemplifying the control mechanism Let’s pick up the simple example of bacterial action on the body cell and the reaction of antibiotics on... Read more »

A Fossils Formidable Years

Ever wonder exactly what a fossil is or where they came from? Fossils are actually the remains of plants or animals that lived millions of years ago. While that is what they are, fossils still to this day serve a very important purpose. They are able to provide some very important information about what life was like millions of years ago. A YouTube video blog from the past, you might say. Only not so annoying. A fossil is a long time in the making. Millions of years actually. A very gradual... Read more »

Fossils - Window Into Our Past

We humans seem to have a rather curious obsession with things that happened in the past. At least humans of the age of 18 seem to. One of the best ways to get a glimpse of the way things used to be is through the analysis of fossils. This is where palaeontologists come in. With their expertise, and the help a few well preserved fossils, it’s truly amazing the things they can find out about our ancient neighbours. When palaeontologists first discover a set of fossils or even old bones, they... Read more »

Aluminum Anodizing Technology and Market Assessment

The rapid growth and widespread use of aluminum since World War II is tied directly to the ability of anodizing processes to protect it from corrosion, improve its appearance by way of brightening it and offering a rainbow of colors, and imparting ceramic-like toughness to its outer skin (especially through hardcoat anodizing). Hydrated aluminum oxide is the stable form of aluminum in nature; thus, unprotected aluminum exposed to air and water will corrode, forming a discontinuous, powdery, white... Read more »

Climate Change - The Coming Crisis

While many contend that there are different reasons behind the changing of our climate, few can deny that our planet is going through a period of immense changes. While some may discredit the science, global warming is one of the main hypothesis for why our planet is heating up. In this article, we’ll try to explain some of the science behind global warming so that you can understand the problem more clearly. According to numerous scientific studies, our planet’s surface temperature has... Read more »

Controversial Research: Embryonic Stem Cells and Obesity Vaccines

In the field of biomedical research, people are often excited when the results of their research are controversial. It evoked limited attention when Cell, a scientific journal in the US, recently reported that some Japanese scientists at Kyoto University claimed that four genes or factors transformed mouse cells to act like ESCs (Embryonic Stem Cells). In contrast, a lot of excitement was created recently when the US, Massachusetts-based, Advanced Cell Research (ATC), claimed in a paper published... Read more »

The Process of Sleep in Humans

Many of us really enjoy falling into bed and drifting off to sleep, particularly after a hard days work. How many of us know what our body goes through during this seemingly simple period of inactivity? Up to the 1950’s sleep was regarded as a time when a persons body and mind shut down for the night. What we now know is that various parts of our brain are in fact very active throughout the time we spend asleep. Time spent asleep is important with preparing us for the challenges of the next... Read more »
