Hornets are insects that are the largest eusocial wasps. Some species can reach up to 5.5 cm (2.2 in) in length. The true hornets make up the genus Vespa and are distinguished from other vespines by the width of the vertex (part of the head behind the eyes), which is proportionally larger in Vespa and by the anteriorly rounded gasters (the section of the abdomen behind the wasp waist). The best known species is the European hornet (Vespa crabro), about 2–3.5 cm in length, widely distributed throughout Europe, Russia, North America and Northeast Asia.

Cordwood construction is a method of natural building that originated roughly one thousand years ago in Greece and Siberia. This method involves using pieces of wood that slightly protrude from the mortar, giving the walls an attractive appearance. Usually, the walls are made 12 to 24 inches thick. However, in some parts of Canada, the walls can be as thick as 36 inches. This method appeals to many people due to its ease of construction economy of resources. Cordwood Construction can be separated into two main types: mortar-insulation-mortar (M-I-M) and Throughwall. M-I-M is a more preferable and widely used choice as it allows for better insulating properties.

Anti-nuclear activists demonstrate during a “Say to Goodbye to Nuclear Energy” protest on September 11, 2011 in Kobe, Japan. Japan is marking sixth months since a magnitude 9.0 earthquake struck Japan offshore on March 11 at 2:46pm local time, triggering a tsunami wave of up to ten metres which engulfed large parts of north-eastern Japan and also damaged the Fukushima nuclear plant, causing the worst nuclear crisis in decades. The current number of dead and missing is reportedly estimated to be 22,900. (Photo by Buddhika Weerasinghe/Getty Images)

My name is Chris Kapono and I am a self-taught artist living in Missouri. I have been drawing and painting ever since I can remember and art has been a big part of my life. My love of animals and nature is reflected in my art and sometimes interesting things I find on walks in the woods will find their way into some of my pieces!

Fossil records indicate that this early lizard, Megalania (Megalania prisca or Varanus priscus), was a whopping seven metres in length. They were part of a megafaunal assemblage that inhabited southern Australia during the Pleistocene. The youngest fossil remains date to around 50,000 years ago. The first aboriginal settlers of Australia might have encountered them and been a factor in their extinction. (Photo by Sky TV/The Guardian)
