Jesse Owens, four-time gold medalist at the 1936 Olympics, raced a horse in Havana, Cuba, winning with a 40-yard lead. After losing his amateur status, Owens struggled financially and later participated in various races. He died at 66 from lung cancer. Four months after winning an unprecedented four gold medals at the 1936 Summer Olympics […]
Human-made objects now weigh more than all living things combined, according to a study by the Weizmann Institute of Science. Infrastructure, plastics, glass, and paper contribute to the mass, while biomass, mainly plants, make up the majority of living things. Human production has increased significantly since the early 20th century, with enough material produced weekly […]
Denmark has 24 million pigs, more than its human population of 5.4 million. The country is the world’s largest pork exporter. Danish pig farms produce enough slurry to fill 90,000 swimming pools annually. Chickens are the most populous livestock globally, while China has the most livestock overall. There are more pigs than humans in Denmark: […]
Humans have a “hedonic set point” for happiness, which varies between individuals. Materialism has a negative effect on happiness, and consciously trying to be happy can backfire. The concept of happiness has evolved over time. Humans can only sustain the feeling of happiness for certain periods of time before returning to a baseline state, sometimes […]
Most mites do not bite humans, but some, such as scabies, bird and rodent mites, grain mites, and chiggers, can cause irritation or itching. Dust mites do not bite humans but can cause allergic reactions. Scabies mites burrow into the skin and lay eggs, while chiggers liquefy the skin to feed. Rodent and bird mites […]
Humans’ preference for sugar is believed to have evolved as a survival technique, as sweetness often indicated safe and energy-providing foods. This preference for high-fat and high-sugar foods may contribute to modern obesity rates. The evolutionary reason for humans’ consumption of sugar is thought to be a result of survival techniques of prehistoric humans who […]
Jurassic Park movies may have influenced polls showing 40% of Americans believe humans and dinosaurs coexisted. Only 54% of respondents in a 2015 poll knew cloning DNA from fossils isn’t feasible. Dinosaurs went extinct before humans appeared on Earth. Jurassic Park and its sequels — including 2015’s record-breaking Jurassic World — have had people in […]
Hair loss is normal as hair goes through three phases of growth: anagen, catagen, and telogen. Daily loss of 50-100 hairs is normal, but anything above 200 is excessive. Age and genetics can influence hair loss, and cutting hair or wearing hats does not cause it. Over-the-counter hair loss products are not always effective, so […]
Scientists have explored the possibility of a manned mission to Mars since 1952, with successful orbital and rover missions providing better understanding of conditions. However, the challenges of a long journey, psychological tolerance, cosmic ray exposure, and payload weight reduction must be overcome. There are currently no solid plans for a manned mission to Mars […]
New research suggests early humans may have been in North America 130,000 years ago, based on mastodon bones found in San Diego in 1992. The bones show signs of impact and were found near five large stones that may have been used as hammers and anvils. Attempts at radiocarbon dating were unsuccessful, so uranium-thorium dating […]

Archaeologists discovered a prehistoric drawing in a South African cave, believed to be the oldest known work of art in the world, around 73,000 years old. The drawing’s criss-cross pattern of red lines resembles Twitter’s hashtag symbol and is considered a “great advance” in human development. The locals most likely used shells to carry the […]
The card catalog was a physical listing of a library’s contents, organized with a single card for each item.

There are several ways […]

They are judged by what a person says, when they say it, and how they say it, as well as body language, eye contact, and gestures. Some people may struggle with social skills due to communication disabilities or […]
Understanding cousin levels can be difficult, as it is based on the common ancestor of two people. First cousins share a grandparent, second cousins share a great-grandparent, and third cousins share a great-great-grandparent. Removals occur when the relationship to the ancestor is generationally separated. Double cousins occur when two sisters marry two brothers. Cousin levels, […]
