The corpse flower (Amorphophallus titanium) is one of the world's stinkiest plants. What makes it smell so bad? Analyses of chemicals released by the plant show the "stench" includes dimethyl trisulfide, dimethyl disulfide, trimethylamine (rotting fish), isovaleric acid (sweaty socks), benzyl alcohol (sweet floral scent), phenol (like Chloraseptic), and indole (like mothballs). While this may be foul smelling to humans, to dung beetles and flies, it smells like opportunity. Insects which feed on dead animals or lay their eggs in rotting meat are attracted to the sent, therefore the smell invite pollinators and scares away humans at the same time. ...

While it may look small now, this baby swordfish (Xiphias gladius) grows fast and can reach 14 feet in length and weigh up to 1,200 pounds as an adult. They are found in the Atlantic, Pacific and Indian oceans and sometimes cold waters, including the Mediterranean Sea, the Sea of Marmara, the Black Sea, and the Sea of Azov. They are highly migratory, moving to warmer waters in the winter and cooler waters in the summer. While they are not at the top of the food chain, it is not a fish to be messed with; apparently, even sharks are wary of them! ...

Not one to be outdone by the dynamic trio of Alvin, Simon, and Theodore of Alvin and the Chipmunks, the least chipmunk (Eutamias Minimus) is the smallest of all chipmunk species (shown above). Least chipmunks range over most of western North America occupying the widest geographic and altitudinal range of any chipmunk. These tiny rodents possess a long, narrow but fairly bushy tail, and have soft, dense fur which is moulted twice a year - the summer coat being brighter in color than the more greyish winter coat. Like other chipmunks, this species has relatively short ears which are covered in short hairs and pouches inside the cheeks which are used to carry food. Interestingly, the female least chipmunk may be slightly larger than the male ...

Some organisms, such as the castor bean plant (Ricinus communis), produce substances that inhibit the synthesis of proteins (called translation) within a cell. (The plant, which is native to Africa, is not related to the species of bean plants with which you are likely more familiar.) A protein called ricin, produced within the castor seeds is an extremely potent inhibitor of protein synthesis. In fact, it is one of the strongest natural toxins produced. A single chewed seed can kill child! If the ricin were purified, it would take an amount equivalent to only a few grains of salt to kill an adult. Ricin kills cells by enzymatically cleaving covalent bonds within the large and small ribosomal subunits, rendering the protein-building factori ...

This blackpoll warbler (Setophaga striata), weighing no more than 12 grams can migrate over the Atlantic Ocean from New England and eastern Canada to the Caribbean islands - a 2500 kilometer flight - nonstop! These finding were discovered after researchers tagged these little birds with miniature geolocators on their backs. They concluded that no other "bird this size migrates for this long in one go... it is truly one of the most amazing migratory feats ever recorded." ...

The Mydas fly (Gauromydas heros) is the world's largest fly. It can reach body lengths of 2.8 inches (7 centimeters) and a wingspan of 4 inches (10 centimeters). Mydas fly are found in arid and semiarid regions of the world, but are infrequently encountered as the adult lifespan can be quite short.

A rare condition, known as situs inversus, is when a person has their major organs mirrored from their normal positions. So, for example, the heart would be on the right side of the body, or the liver and gall bladder are on the left side. It is a congenital condition (meaning it's tied to your genetics) that affects 1 in 20,000 people - including Spanish-born singer Enrique Iglesias.
