It’s funny how we compulsively wash our hands, spray our countertops, or make a grimace when someone sneezes near us, when, in fact, each and every one of us is a walking petri dish! All the bacteria living inside you could fill a half-gallon jug — there are 10 times more bacterial cells in your body than human cells, according to Carolyn Bohach, a...
Everybody knows that there are at least three states of matter: solid, liquid, and gas. If you’re a little bit more versed in physics, you also know about the fourth fundamental state of matter called plasma — a hot ionized gas, with prime examples including lightning or neon signs. But beyond these common states of matter, scientists have discover...
Despite their name, killer whales or orcas are the largest members of the dolphin family. Technically, orcas are also whales because delphinids belong to the Cetacean order within the toothed whale (Odontoceti) suborder. However, the term whale is typically reserved for baleen whales of theMysticetisuborder. The major physical feature that ensures ...
Unlike humans, grasshoppers do not have ears on the side of their heads. Like the ears of people, the grasshopper sound detector is a thin membrane called a tympanum, or “eardrum”. In adults, the tympanum is covered and protected by the wings, and allows the grasshopper to hear the songs of its fellow grasshoppers. The grasshopper tympanum is adapt...
In order for food to have taste, chemicals from the food must first dissolve in saliva. It’s only once they’ve been dissolved in a liquid that the chemicals can be detected by receptors on taste buds. During this process, some salivary constituents chemically interact with taste substances. For example, salivary buffers (e.g., bicarbonate ions) dec...
Two of the hearts work exclusively to move blood beyond the animal’s gills, while the third keeps circulation flowing for the organs. When the octopusswims, the organ heart stops beating, which explains why these creatures prefer to crawl rather than swim (it exhausts them). An octopus also has nine brains — well, sort of. There’s one ‘main’ brain ...
There are between 100,000,000,000 and 1,000,000,000,000 stars in a normal galaxy. In the Milky Way alone there might be as many 100 billion Earth-like planets. Still think we’re alone?
In certain conditions, hot water can freeze faster than cold water — a counter-intuitive phenomenon known as the Mpemba effect. There is a number of proposed explanations for the Mpemba effect, including faster evaporation of hot water that reduces the volume left to freeze, the formation of a frost layer on cold water that insulates it, or differe...
According to research from the University of Cambridge, humans have evolved with genes acquired from plants and fungi. But how did they get there? Rather than a straightforward single-branching tree where genes are inherited from parents, scientists argue that sometimes foreign genes may spread by a process known as horizontal gene transfer. For in...
A 2016 study by biologists at the Salk Institute in La Jolla, California, shook the field of neuroscience, finding that the human brain’s memory capacity exceeded previous conservative estimates by a factor of 10. They calculated that the typical human brain could store one petabyteof information or a quadrillion bytes. To put this figure into pers...
