Measles is a highly infectious condition Scientists have identified 21 strains of the measles virus Symptoms of measles can include watery eyes, sneezing, and a dry hacking cough There is no specific treatment for measles. Prevention is better than cure and Pregnant women should not take the vaccine.

A bacterial infection is a proliferation of a harmful strain of bacteria on or inside the body. Bacteria can infect any area of the body. Pneumonia, meningitis, and food poisoning are just a few illnesses that may be caused by harmful bacteria. Bacteria come in three basic shapes: rod-shaped (bacilli), spherical (cocci), or helical (spirilla). Bacteria may also be classified as gram-positive or gram-negative. Gram-positive bacteria have a thick cell wall while gram-negative bacteria do not. Gram staining, bacterial culture with antibiotic sensitivity determination, and other tests are used to identify bacterial strains and help determine the appropriate course of treatment.

A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is possible is called the event horizon. Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, no locally detectable features appear to be observed.In many ways a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe.

Earth is the third planet from the Sun and the only astronomical object known to harbor life. According to radiometric dating and other sources of evidence, Earth formed over 4.5 billion years ago. Earth's gravity interacts with other objects in space, especially the Sun and the Moon, Earth's only natural satellite

A quantum computer harnesses some of the almost-mystical phenomena of quantum mechanics to deliver huge leaps forward in processing power. Quantum machines promise to outstrip even the most capable of today’s—and tomorrow’s—supercomputers. They won’t wipe out conventional computers, though. Using a classical machine will still be the easiest and most economical solution for tackling most problems. But quantum computers promise to power exciting advances in various fields, from materials science to pharmaceuticals research. Companies are already experimenting with them to develop things like lighter and more powerful batteries for electric cars, and to help create novel drugs.

Think about the cell phone and computer you use every day to do your job. Think about the car you drive to take to work. Think about the food you eat; water you drink; clothes you wear; and appliances you use to store, prepare, and clean them. Think about the television you watch, video games you play, or music system you listen to. Think about the buildings you visit. Think about any modern convenience or necessity. Just about anything you can think of is the result of complex processes. Without talented individuals to design, build, improve, and maintain these processes, these technological advances would never have occurred and future innovations would be impossible. Without automation professionals, our world and our future would be very different.

Depression affects an estimated one in 15 adults (6.7%) in any given year. And one in six people (16.6%) will experience depression at some time in their life. Depression can strike at any time, but on average, first appears during the late teens to mid-20s. Women are more likely than men to experience depression. Some studies show that one-third of women will experience a major depressive episode in their lifetime.

Obsessive-compulsive disorder is characterised by unreasonable thoughts and fears (obsessions) that lead to compulsive behaviours. OCD often centres on themes such as a fear of germs or the need to arrange objects in a specific manner. Symptoms usually begin gradually and vary throughout life. Treatment includes talk therapy, medication or both.

The Cold War was a period of geopolitical tension between the Soviet Union with its satellite states (the Eastern Bloc), and the United States with its allies (the Western Bloc) after World War II. A common historiography of the conflict begins between 1946, the year U.S. diplomat George F. Kennan's "Long Telegram" from Moscow cemented a U.S. foreign policy of containment of Soviet expansionism threatening strategically vital regions, and the Truman Doctrine of 1947, and ending between the Revolutions of 1989 and the 1991 collapse of the USSR, which ended communism in Eastern Europe. The term "cold" is used because there was no large-scale fighting directly between the two sides, but they each supported major regional conflicts known as proxy wars. The conflict split the temporary wartime alliance against Nazi Germany, leaving the USSR and the US as two superpowers with profound economic and political differences.

In time, a neutral bloc arose in these regions with the Non-Aligned Movement, which sought good relations with both sides. Notwithstanding relatively isolated incidents of air-to-air dogfights and shoot-downs, the two superpowers never engaged directly in full-scale armed combat. However, both were heavily armed in preparation for a possible all-out nuclear world war. Each side had a nuclear strategy that discouraged an attack by the other side, on the basis that such an attack would lead to the total destruction of the attacker—the doctrine of mutually assured destruction (MAD). Aside from the development of the two sides' nuclear arsenals, and their deployment of conventional military forces, the struggle for dominance was expressed via proxy wars around the globe, psychological warfare, massive propaganda campaigns and espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race..
