Ever thought of how it would be without war, a world without clash of interest, a world filled with individuals, groups and states that never growled at each other?. Conflicts are essential part of human existence, but arguably not war, which is the apex of conflicts. Many theorists have tried to conjure an exact definition for this state of being. War isn't only a thing of physical occurrence as it is also a state of mind, this constitute a major problem as they try to come up with a true definition of the term 'war'. The following are the different views on what war is:   🎤War is a state of armed conflict between societies. It is generally characterized by extreme aggression, destruction, and mortality, using regular or irregular military forces. An absence of war is usually called "peace". Warfare refers to the common activities and characteristics of types of war, or of wars in general. Total war is warfare that is not restricted to purely legitimate mili

With their treelike height, thin legs and awkward locomotion, giraffes are the epitome of the word "gangly." But do their sexual behaviors involve smoother actions than one would assume from their appearance? Like people, giraffes mate year-round, though there's some indication that breeding times correspond with periods of high food availability. The tall ungulates live in a so-called fission-fusion society, in which the size and the composition of herds continually shift — the social mammals use this ever-changing society to find mates. "The best way to describe it: Giraffes live in a permanent cocktail party," said Fred Bercovitch, a biologist at Kyoto University in Japan who has studied the reproductive and social behaviors of giraffes. "At a cocktail party, you'll see there are some people who are really social butterflies and spend a little bit of time mingling with a lot of people, and others who spend more time with fewer people." And th

Leprosy may conjure up images of lost limbs and isolated colonies, but the disease is actually much less extreme and completely treatable today. The modern name for leprosy is Hansen's disease; it's caused by the bacterium Mycobacterium leprae. The disease causes skin lesions and can permanently damage a person's nerves; however, it is a misconception that it causes people's body parts to fall off. Here are six strange facts about leprosy. 1. Leprosy cases still occur, even in the U.S. Although leprosy is often thought of as an ancient disease, people can still become infected with the bacteria that cause the disease. Indeed, a case of leprosy was reported in a California schoolchild in September 2016, and several cases pop up each year across the southern United States, including in Florida, Louisiana and Texas. In 2014, there were 175 cases of leprosy reported in the U.S., according to the National Hansen's Disease Program (NHDP). Typically, between 150 and

Smoking marijuana may increase the risk of experiencing an episode of psychosis, or a break with reality, in people who have already had such an episode, according to a new study. In the study, researchers looked at about 200 patients in England who had been diagnosed with psychosis at least two years before the start of the study, and asked them about their marijuana use. The researchers found that those who used marijuana during the two years after they experienced their first episode of psychosis had a 13 percent higher chance of experiencing another episode of psychosis during this time, compared with people who did not smoke marijuana during the first two years after being diagnosed. However, it is important to put these estimates into context, said study co-author Sagnik Bhattacharyya, a researcher who studies psychosis at King's College London. "Patients with psychosis already have a high risk of relapse even if they do not use cannabis," he said. The estimates p

Taste, smell, vision, hearing, touch and… awareness of one's body in space? Yes, humans have at least six senses, and a new study suggests that the last one, called proprioception, may have a genetic basis. Proprioception refers to how your brain understands where your body is in space. When police ask a drunken person to touch their finger to the tip of their nose, they're testing the sense of proprioception. Previous research in mice has suggested that a gene called PIEZO2 may play a role in this sense, according to the study. The PIEZO2 gene tells cells to produce "mechanosensitive" proteins. Mechanosensation is the ability to sense force, for example, being able to feel when someone presses down on your skin. It also plays a role in proprioception, according to the study. To understand the gene's effect in humans, the researchers at the National Institutes of Health (NIH) identified two young patients who had very rare mutations in the gene, according to th

Many people have seen a movie in which a drunk character accuses everyone else of being drunk too. But a new study from the United Kingdom suggests that in real life, being surrounded by sober individuals may actually have a, well, sobering effect. The researchers found that people who were surrounded by other intoxicated individuals were more likely underestimate their own level of drunkenness. But when more sober people were present, drinkers tended to overestimate their own drunkenness, the study found. In other words, if that drunk person in the movie was actually surrounded by sober people, he or she would be more likely to realize it — and to think of himself as drunker than them. [7 Ways Alcohol Affects your Health] "Researchers have historically worked under the assumption that those who drink [the] most alcohol incorrectly 'imagine' everyone else also drinks to excess," Simon Moore, a professor of public health research at Cardiff University in Wales and t

A healthy back is important not just for exercising and playing sports but also for performing everyday tasks, from tying your shoes to cleaning the house. Certain exercises can help prevent back injuries, but it's important to know which ones will help you and which ones could actually lead to injury. There is a lot of information out there on back exercises, and some tips are more useful and accurate than others. At Live Science, we've done the research, looking at studies and talking to top experts. So, when it comes to figuring out the best ways to exercise your back, we've got your… well, you know. Having a "healthy back" means more than just having strong back muscles; the muscles need to be able to work together properly to stabilize your spine, said Stuart M. McGill, director of the Spine Biomechanics Laboratory at the University of Waterloo in Ontario and author of "Back Mechanic" (Backfitpro Inc, 2015) "It's not always about strengt
