Smart Crow is a Great Problem Solver
Crows are some of the smartest creatures in the animal kingdom. They are capable of making rule-guided decisions and of creating and using tools. They also appear to show an innate sense of what numbers are.
Researchers now report that these clever birds are able to understand recursion—the process of embedding structures in other, similar structures—which was long thought to be a uniquely human ability.

Beautiful Aurora Borealis over the Mountains of Switzerland 5-10-2024
Beautiful Aurora Borealis over the Mountains of Switzerland
5-10-2024
An aurora also commonly known as the northern lights - aurora borealis - or southern lights (aurora australis),[c] is a natural light display in Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras display dynamic patterns of brilliant lights that appear as curtains, rays, spirals, or dynamic flickers covering the entire sky.
Auroras are the result of disturbances in the Earth's magnetosphere caused by the solar wind. Major disturbances result from enhancements in the speed of the solar wind from coronal holes and coronal mass ejections. These disturbances alter the trajectories of charged particles in the magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/exosphere). The resulting ionization and excitation of atmospheric constituents emit light of varying colour and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles.

Super Happy Dog Loves Playing in the Rain
Super Happy Dog Loves Playing in the Rain
The dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of the wolf. Also called the domestic dog, it is derived from extinct gray wolves, and the gray wolf is the dog's closest living relative. The dog was the first species to be domesticated by humans. Experts estimate that hunter-gatherers domesticated dogs more than 15,000 years ago, which was before the development of agriculture. Due to their long association with humans, dogs have expanded to a large number of domestic individuals and gained the ability to thrive on a starch-rich diet that would be inadequate for other canids.
The domesticated dog apparently originated as a predator and scavenger.[147] Domestic dogs inherited complex behaviors, such as bite inhibition, from their wolf ancestors, which would have been pack hunters with complex body-language. These sophisticated forms of social cognition and communication may account for dogs' trainability, playfulness and ability to fit into human households and social situations,[148] and probably also their co-existence with early human hunter-gatherers.
Dogs perform many roles for people, such as hunting, herding, pulling loads, protection, assisting police and the military, companionship and aiding disabled individuals. These roles in human society have earned them the nickname "man's best friend" in the Western world. In some cultur

Worker saves kitten from trash machine
Worker saves kitten from trash machine
Waste compaction, often using a trash machine, is the process of compacting waste, reducing it in size. Garbage compactors and waste collection vehicles compress waste so that more of it can be stored in the same space. Waste is compacted again, more thoroughly, at the landfill to conserve valuable airspace and to extend the landfill's life span
A kitten is a juvenile cat. After being born, kittens display primary altriciality and are fully dependent on their mothers for survival. They normally do not open their eyes for seven to ten days. After about two weeks, kittens develop quickly and begin to explore the world outside their nest. After a further three to four weeks, they begin to eat solid food and grow baby teeth. Domestic kittens are highly social animals and usually enjoy human companionship.

Shark swallows diver’s camera, captures video inside shark’s body
Shark swallows diver’s camera, captures video inside shark’s body
Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the Batoidea (rays and kin). Some sources extend the term "shark" as an informal category including extinct members of Chondrichthyes (cartilaginous fish) with a shark-like morphology, such as hybodonts. Shark-like chondrichthyans such as Cladoselache and Doliodus first appeared in the Devonian Period (419–359 million years), though some fossilized chondrichthyan-like scales are as old as the Late Ordovician (458–444 million years ago). The oldest confirmed modern sharks (selachimorphs) are known from the Early Jurassic, about 200 million years ago, though records of true sharks may extend back as far as the Permian

Footage of a humpback whale breaching
Footage of a humpback whale breaching. Despite being this massive, it’s only half the size of a blue whale
The humpback whale (Megaptera novaeangliae) is a species of baleen whale. It is a rorqual (a member of the family Balaenopteridae) and is the only species in the genus Megaptera. Adults range in length from 14–17 m (46–56 ft) and weigh up to 40 metric tons (44 short tons). The humpback has a distinctive body shape, with long pectoral fins and tubercles on its head. It is known for breaching and other distinctive surface behaviors, making it popular with whale watchers. Males produce a complex song typically lasting 4 to 33 minutes.

How deep are gas station tanks buried?
Gas station tanks are typically buried underground to maximize space utilization and minimize environmental impact. Underground storage tanks (USTs) are commonly used to store gasoline, diesel
One important factor that influences the depth of burial is local regulations. Governments around the world have established specific guidelines or codes that dictate how deep gas station tanks should be buried

Huge waves hitting the coast of San Sebastian, Spain sends people scattering
Huge waves hitting the coast of San Sebastian, Spain
What causes ocean waves?
Waves are caused by energy passing through the water, causing the water to move in a circular motion.
Looking out at the ocean, you often see a seemingly infinite series of waves, transporting water from one place to the next. Though waves do cause the surface water to move, the idea that waves are travelling bodies of water is misleading.
Waves are actually energy passing through the water, causing it to move in a circular motion.

A Smart Raven wins Tic-tac-toe
A Raven wins Tic-tac-toe
The intriguing Common Raven has accompanied people around the Northern Hemisphere for centuries, following their wagons, sleds, sleighs, and hunting parties in hopes of a quick meal. Ravens are among the smartest of all birds, gaining a reputation for solving ever more complicated problems invented by ever more creative scientists. These big, sooty birds thrive among humans and in the back of beyond, stretching across the sky on easy, flowing wingbeats and filling the empty spaces with an echoing croak.
A raven is any of several larger-bodied passerine bird species in the genus Corvus. These species do not form a single taxonomic group within the genus. There is no consistent distinction between crows and ravens. Names are assigned to different species chiefly based on their size
Common Raven or Northern Raven (Corvus corax), found in the Holarctic south throughout Middle Europe, North Africa, Western Siberia, Asia, Greenland.and North America to Nicaragua.
Western Raven (Corvus [corax] sinuatus), found in the Arctic, North America, Eurasia, Northern Africa, Pacific islands and British Isles
Brown-necked Raven or Desert Raven (Corvus ruficolis), found in Northern Africa, Arabia, Southeast to Eastern Asia
Australian Raven (Corvus coronoides), found in Eastern and Southern Australia
Little Raven (Corvus mellori), found inSoutheastern Australia
Forest Raven or Tasmanian Raven (Corvus tasmanicus ), found in Tasmania and the adjacent south coast of Australia

Introduction to the Dial Telephone, 1936
Introduction to the Dial Telephone, 1936
A rotary dial is a component of a telephone or a telephone switchboard that implements a signaling technology in telecommunications known as pulse dialing. It is used when initiating a telephone call to transmit the destination telephone number to a telephone exchange
On the rotary dial, the digits are arranged in a circular layout, with one finger hole in the finger wheel for each digit. For dialing a digit, the wheel is rotated against spring tension with one finger positioned in the corresponding hole, pulling the wheel with the finger to a stop position given by a mechanical barrier, the finger stop. When released at the finger stop, the wheel returns to its home position driven by the spring at a speed regulated by a governor device. During this return rotation, an electrical switch interrupts the direct current (DC) of the telephone line (local loop) the specific number of times associated with each digit and thereby generates electrical pulses which the telephone exchange decodes into each dialed digit. Thus, each of the ten digits is encoded in sequences to correspond to the number of pulses; thus, the method is sometimes called decadic dialing. Pulse count dialing is a digital addressing system which uses decimal pulse count modulation. The typical average baud rate is 10 bits per second, though the system will usually accept from about 9 through 13 pulses per second, a requirement due to variations in the rotary dial mechanism governor speed

What flight looks like from an eagles' perspective
What flight looks like from an eagles' perspective
Eagle is the common name for the golden eagle, bald eagle, and other birds of prey in the family Accipitridae. Eagles belong to several groups of genera, some of which are closely related. True eagles comprise the genus Aquila. Most of the 68 species of eagles are from Eurasia and Africa. Outside this area, just 14 species can be found—two in North America, nine in Central and South America, and three in Australia
Eagles are often informally divided into four groups.[a][22]
The snake eagles are placed in the subfamily Circaetinae. The fish eagles, booted eagles, and harpy eagles have traditionally been placed in the subfamily Buteoninae together with the buzzard-hawks (buteonine hawks) and harriers. Some authors may treat these groups as tribes of the Buteoninae; Lerner & Mindell[23] proposed separating the eagle groups into their own subfamilies of Accipitridae
