By The Time I Get Into Bed, I Find Myself Picking Up My Phone And Just Scrolling And Scrolling And Scrolling.

By the time I get into bed, I find myself picking up my phone and just scrolling and scrolling and scrolling. I stay up past my bedtime, despite being exhausted and knowing I'd be better off going to sleep. This behavior is called "revenge bedtime procrastination."

"Revenge bedtime procrastination" refers to a phenomenon where individuals, who feel that they lack control over their daytime activities, intentionally delay going to bed as a way to reclaim a sense of freedom and leisure during the late evening or early morning hours. This behavior often involves staying up late to engage in activities such as watching TV, browsing the internet, playing video games, or using social media.

Does a plane have a horn? Let's find out.

The use of horns in the air is not practical due to the vast distances and three-dimensional airspace involved in aviation. However, an aircraft still has a 'make some noise' button, at least something similar to traditional horns.

Airbus, it is your turn.

Meet the Caribbean reef octopus (Octopus briareus)! This reef-inhabiting cephalopod lives in warm shallow waters, spanning southern Florida to the Caribbean, through to South America’s northern coast. It’s distinguished by its eye-catching blue coloring, but this master of disguise can change its looks in an instant. Like other octopuses, it uses pigmented cells in its skin, called chromatophores, to alter its appearance. When confronted by a foe, such as a shark, it may emit a cloud of unpleasant-tasting ink to deter its enemy from further pursuit.

The most basic definition of black ice is a thin coat of highly transparent ice. The reason it is transparent is because it blends in with road pavements since it is so thin, making it nearly impossible to see. It's called black ice since it looks black, like the color of the road pavement it forms on.

So long, and thanks for all the fish

Dolphins are known for their high level of intelligence among non-human animals. While brain size is one factor often considered in discussions of intelligence, it's important to note that intelligence is a complex trait influenced by various factors.

Dolphins, particularly species like bottlenose dolphins, have large and highly developed brains relative to their body size. The encephalization quotient (EQ), which measures brain size relative to body size, is often used to compare the intelligence of different species. Dolphins have relatively high EQs, indicating that their brains are larger than expected for an animal of their size.

Dolphins are renowned for their intricate communication skills, employing a diverse range of vocalizations, body language, and distinctive whistles. Their communication is not only used for basic interaction but also for conveying complex information within their social groups. The ability to convey and understand various messages suggests a high level of cognitive sophistication.

Research has confirmed that dolphins engage in cooperative problem-solving. They often work together to achieve common goals, such as hunting for prey or navigating challenging environments. Dolphins have been observed using coordinated tactics to corral fish into tight groups, making it easier for them to capture their prey. This collaborative approach to problem-solving reflects a high level of social intelligence and effective communication within dolphin pods.

Dolphins are known for their ability to teach and learn from one another. This includes the transmission of behaviors and skills within the group, a phenomenon known as cultural transmission. Dolphins can pass on knowledge about hunting techniques, communication signals, and other behaviors to younger or less experienced members of the pod. This cultural exchange contributes to the transmission and preservation of complex behaviors across generations.

Another indicator of advanced cognitive abilities is self-awareness, and dolphins have demonstrated this trait. Through the mirror test, where animals recognize themselves in a mirror, dolphins have displayed a level of self-awareness. This suggests a cognitive capacity for introspection and an understanding of one's own identity, a characteristic shared by a select group of intelligent species.

While not as extensively studied as in some other intelligent species, there is evidence that dolphins engage in tool use. For instance, some dolphins use sponges to protect their snouts while foraging on the ocean floor. This behavior reflects a certain level of cognitive flexibility and innovation, as dolphins adapt objects from their environment for specific purposes, showcasing a capacity for tool use.

The first known online transaction took place in 1971 when students at Stanford University used the ARPANET (a precursor to the internet) to arrange the sale of a small amount of marijuana. The transaction was between students in the artificial intelligence lab at Stanford and students at the Massachusetts Institute of Technology (MIT). However, it doesn't technically qualify as a transaction because no money was exchanged online; the network was solely used to coordinate a meeting place. So, what was the first thing ever sold online?
