Do fat people stay warmer than thin people?
Pack on some extra pounds for winter

At the yearly Rottnest Channel Swim in Western Australia, participants often smear their bodies with animal fat for insulation against the 70-degree water. But their own body fat also helps to keep them warm, like an extra layer of clothing beneath the skin. When scientists studied aspects of the event in 2006, they found that swimmers with a greater body mass index (BMI) appear to be at much lower risk of getting hypothermia.
The same effect has been demonstrated in hospitals where patients who’ve suffered cardiac arrest are treated with “therapeutic hypothermia” to stave off brain injury and inflammation. Studies have shown that it takes longer to induce hypothermia in obese patients than in their leaner counterparts. The extra fat seems to insulate the body’s core.
Under certain conditions, though, overweight people might feel colder than people of average weight. That’s because the brain combines two signals — the temperature inside the body and the temperature on the surface of the skin — to determine when it’s time to constrict blood vessels (which limits heat loss through the skin) and trigger shivering (which generates heat). And since subcutaneous fat traps heat, an obese person’s core will tend to remain warm while his or her skin cools down. According to Catherine O’Brien, a research physiologist with the U.S. Army Research Institute of Environmental Medicine, it’s possible that the lower skin temperature would give fatter people the sense of being colder overall.
But O’Brien points out that many other factors beyond subcutaneous fat help determine the rate at which we chill. Smaller people, who have more surface area compared to the total volume of their bodies, lose heat more quickly. (It’s often said that women feel colder than men; average body size may play a part.) A more muscular physique may also offer some protection against hypothermia, partly because muscle tissue generates lots of heat. “We have a joke around here that the person who’s best-suited for cold is fit and fat,” says O’Brien.

Al Capone
Born in 1899 in Brooklyn, New York, to poor immigrant parents, Al Capone went on to become the most infamous gangster in American history. In 1920 during the height of Prohibition, Capone’s multi-million dollar Chicago operation in bootlegging, prostitution and gambling dominated the organized crime scene. Capone was responsible for many brutal acts of violence, mainly against other gangsters. The most famous of these was the St. Valentine’s Day Massacre in 1929, in which he ordered the assassination of seven rivals. Capone was never indicted for his racketeering but was finally brought to justice for income-tax evasion in 1931. After serving six-and-a-half years, Capone was released. He died in 1947 in Miami. Capone’s life captured the public imagination, and his gangster persona has been immortalized in the many movies and books inspired by his exploits.

Green sea turtle
Green sea turtles spend most of their lives underwater, where they can rest for up to five hours at a time before coming up for air. When active, they typically alternate between being underwater for a few minutes and coming up to the surface to breathe air for a few seconds. Green sea turtles are also known to sunbathe on land.Unlike most other sea turtles, adult green sea turtles eat a primarily plant-based diet consisting of seaweed and sea grass. Scientists believe these green foods give the sea turtle’s fat its green color. The shell of the green sea turtle is usually shades of a brown or olive color.

One of the negative effects of industrialization on human activity and the environment is the production of excessive light. Most people do not consider the surplus of artificial light as a form of pollution because it is not permanent; all we must do is collectively turn out our lights to make it disappear. In reality, however, such a solution is unrealistic because our society needs artificial light to function. Light pollution is mainly caused by lighting systems that are misdirected, excessive, inefficient or unnecessary. The negative effects of light pollution on human activity are numerous. From an economic point of view, for example, the use of excessive lighting or unnecessary lighting constitutes a waste of energy that is costly to both the individual and to industries. On a larger scale, excessive lighting can have an impact on global climate change if the required electricity was generated by burning fossil fuels. Wildlife and plants are also affected. For example, nighttime lighting can confuse animals that migrate (like migratory birds), can modify predator-prey relationships, and can even alter competitiveness within the same species.
