In our Biology class we learn that we have two lungs, the left and the right. Looking deeper, we observe that the left lung seems to only have two lobes, while the right lung has three. The right lung may be shorter, but it’s wider than the left. Why does our right lung have three lobes and is wider than the left lung? The answer is to make space for […]

Observers of American politics have already said this: the U.S. Government is strongly supportive of Israel. Despite Israel’s socio-political activities against Palestine and Lebanon, the United States continues to funnel economic and military aid to Israel’s coffers. Why does the U.S. support Israel? The reasons may be found in three contexts: historical, religious, and economic. In History The historical connections of Israel with the Western countries began after World War […]

Unlike climates that normally stays the same for much longer periods, weather changes so often each day or each hour. One day we have sunny skies, the next day we’ll have a cloudy day. Sometimes, it would be rainy one morning, and sunny and warm in the afternoon. The weather changes so often it is difficult to predict. But why and how does the weather change? Air Mass and Pressure […]

Our lungs are two large balloon-like organs inside our chest cavity, nestled behind our heart and the upper part of our stomach. Through the help of the lungs and the body’s circulatory system, oxygen is distributed to internal organs, and carbon dioxide is expelled from the body. This pair of spongy organs is normally filled with air, and not fluids. However, when fluids build up inside the lungs, it prevents […]

Let’s admit it: Smoking feels good. Each deep drag triggers pleasure receptors in the brain. Dopamine, the “happy” hormone, is released, and as a result, smokers feel “high” without the bad effects, which include drowsiness, depression, and even hallucinations. Those bad effects, however, are just superficial. What really hurts smokers the most are the hidden effects smoking has on the human body. One of these is an immediate increase in […]

The Tower of Pisa wasn’t leaning when it was built in 1173; it was as straight as a pole. It only began to shift direction shortly after construction due to a poorly built foundation and a loose layer of subsoil. It was leaning to the southeast, at first, before the unstable foundation shifted and started leaning towards the southwest. After a phase of structural strengthening in the early twenty-first century, […]

Passover is a Jewish holiday celebrated in remembrance of the flight of Jews from Egypt. From our Bible studies, we know that the Pharaoh had initially refused to let the Jews go as he ahd first promised to Moises. When he reneged on this promise, God sent ten plagues to devastate only the Egyptians’ health and way of life. They were attacked by pests, suffered from boils, and in the […]

In the early days, phone lines were the only connection used to access the World Wide Web. Now that technology has advanced rapidly, we are presented with more and better choices for connecting. Aside from dial-up, we can use broadband connections through DSL, ADSL, or wireless. Unlike dial-up, which has a bitrate of 56 kilobits per second or even less, broadband offers a faster Internet access with 64 kilobits per […]

There are a lot of reasons that our faces go red. It may be because we were embarrassed, or we have been engaging in a strenuous activity, or we have been crying. The reasons and the situations differ, but the result is the same: we are left with a tell-tale sign on our face. One look and our friends would ask: What happened? And, we’d be asking ourselves that same […]

For most people, chest pain usually means heart pain because that is where our most vital organs are found. Aside from the heart, our organs – lungs, esophagus, diaphragm, and stomach – are covered by our ribs and muscles in a tight embrace protecting them from injury and external pressure. Feeling chest pains, therefore, can signal a life-threatening condition, and its cause can be attributed to anything from heart failure […]
