Don’t shake hands with this baby! To mark its territory and improve its grip, the Senegal bush baby urinates on its own hands—leaving its aroma behind as it moves through the trees. Also known as the Northern lesser galago (Galago senegalensis), this diminutive critter only weighs up to 0.7 lbs (0.3 kg).

It’s nocturnal, typically spending daylight hours snoozing in hollow trees or abandoned birds’ nests. By night, it’s an active omnivore, using its large eyes and ears to find food. Its diet includes seeds, eggs, and insects. On solid ground, the bush baby moves by hopping, but in the trees it prefers to leap and climb. It can be found in parts of Africa including Ethiopia and Senegal.

In this orchestra, a woman plays an instrument called a "Theremin," it is a quantum instrument played only with the energy of the hands, an instrument that forms a magnetic field and is played untouched.

Only three countries in the world have music schools that teach theremin: Russia, Japan and Ireland. The theremin was invented by Leon Theremin, a Russian who introduced it to Lenin in 1920. 🤔

Good morning yall! Hope you're ready for a new fish today cuz we got an all timer here today!

Today's fish is none other than my personal favorite fish, the Brook Trout (salvelinus fontinalis)! These beauties are native to Eastern North America, in both Canada and the United States, ranging from Lake Superior, to the coastal waterways from the Hudson Bay to Long Island, though they have spread far beyond their native ranges, mostly via aquacultural practices and artificial propagation, making them invasive species in many regions of North America and the world at large!

Two ecological forms of Brook Trout have been recognized by the US Forest Service, the longer-living potamodromous (fish whose migration occurs fully within fresh water) population, known as coasters , and the anadromous (fish whose migration occurs from fresh water to salt water) population, known as salters. Adult coasters typically reach lengths over 2 feet in length and weigh up to 15lbs, compared to adult salters, which average between 6 to 15 inches and about 5lbs. They're characterized by their vibrant coloration, with olive green bodies and spectacular yellow and blue rimmed red spots, white and black trimming along their orange fins, and dense, irregular lines along the top of their bodies. Often, the bellies of male Brook Trout becomes bright red or orange when spawning.

During the spawning season, female Brook Trout will construct a depression in the stream bed, referred to as a "redd", where groundwater percolates upward through the gravel. Male Brook Trout will approach the female, fertilizing the eggs. The eggs are only slightly denser than water, and can easily be swept away by the current. To avoid this, the female will bury the eggs in a small gravel mound, from which they hatch 4 to 6 weeks later. During this incubation period, the eggs receive oxygen from the streamwater that passes through the gravel beds and into their gelatinous shells. Once they hatch into small fry fish that retain their yolk sack for nutrients, which compensates for the lack of nutrients provided by the parents during the early stages of development. Following the consumption of the yolk, the fry Brook Trout will shelter from predatory species in rocky crevices and inlets, growing from fry to fingerlings, until reaching full maturation at the ripe old age of 6 months.

Despite their native range spanning across low-elevation lakes and watersheds, Brook Trout are increasingly confined to higher elevations in the Appalachian Mountains, especially in southern regions of Appalachia. Over seas, however, Brook Trout have thrived in introduced populations in much of Europe, Argentina, and New Zealand since as early as the 1850's! Their typical habitats include large and small lakes, rivers, creeks, and spring ponds in cold temperate climates. They thrive in clear spring water with moderate flow rates and healthy vegetation populations and other resources which provide natural hiding places. Although they are more resilient and adaptable to varying environmental changes, such as pH levels and temperatures, Brook Trout struggle in temperatures warmer than 72 degrees Fahrenheit. Their diets include aquatic insects at all stages of life, adult terrestrial insects such as grasshoppers and crickets, crustaceans and frogs, molluscs, invertebrates, smaller fish, and even small aquatic mammals such as voles, and even other young Brook Trout! This highly indiscriminate diet and environmental resiliency allows for their success across the globe.

Given all of this, Brook Trout are classified as a Secure by NatureServe's conservation metrics, but that label may be misleading; these incredible fish face severe and repeated extirpation (localized extinction) in many of their native habitats due to habitat destruction, pollution, damming, and invasive species. Meanwhile, Brook Trout present the danger of extirpation to other fish in their nonnative habitats, indicating that efforts must be taken to curb these populations. In short, there are more than enough Brook Trout, but they simply are not where they are meant to be.

A true fish out of (the specifically correct body of) water, the Brook Trout scores within the top percentile of all fishies on our highly advanced fish ranking scale.

The Oldest Surgical Treatise (That We Know Of)

The Edwin Smith Papyrus is the only surviving section of a treatise on trauma surgery. Written circa 1600 BCE, it describes 48 traumatic injury cases, how to treat them, and the final prognosis. Surprisingly, magic is only listed as the treatment for one case.

When it was first discovered in the 1800s, it was a little over 4.5 metres long. Which, if you're familiar with 19th century Egyptology, naturally means some rich dude cut it up (into 17 columns).

No, it’s not a muppet. This unforgettable primate, found in the mangrove forests of Borneo, is the proboscis monkey (Nasalis larvatus)! Also known as the long-nosed monkey, males of this species sport a distinctive drooping proboscis, which acts like a resonating chamber to amplify their vocalizations. Scientists think it’s a sexually selected trait—meaning that females prefer louder (and bigger-nosed) mates.
