A rare mutation among the Bajau people lets them stay underwater longer: natural selection at the PDE10A gene has increased spleen size in the Bajau, providing them with a larger reservoir of oxygenated red blood cells.

Rare Mutation Among Bajau People Lets Them Stay Underwater Longer The Bajau people of Malaysia and the Philippines are renowned for their free-diving abilities, often working eight-hour shifts in search of fish and other sea critters. Underwater sessions can last upwards of two minutes, with accumulated daily totals of breath-holding often reaching five hours. New …

It’s been 125,000 generations since the emergence of human species, 7,500 generations since human physiology reached what is essentially its modern state, 500 generations since the agricultural revolution, and ONLY 20 generations since the scientific revolution!

Sapiens: A Brief History of Humankind Sapiens: A Brief History of Humankind (Hebrew: קיצור תולדות האנושות‎, [Ḳitsur toldot ha-enoshut]) is a book by Yuval Noah Harari first published in Hebrew in Israel in 2011,[1] and in English in 2014.[2][3] The book surveys the history of humankind from the evolution of archaic human species in the …

Here’s a fact about the Murchison meteorite, which fell to earth in 1969. It contained high levels of organic compounds, came from a parent body that had liquid water, and the amino acids it contained could not have been synthesized on earth because they consisted of both left- and right- isomers.

Murchison meteorite The Murchison meteorite is a large meteorite that fell to earth near Murchison, Victoria, in Australia, in 1969. It is one of the most studied meteorites due to its mass (>100 kg (220 lb)), the fact that it was an observed fall, and that it belongs to a group of meteorites rich in …

Jupiter’s Great Red Spot is so loud, it’s acoustic sound waves heat up the surrounding atmosphere to almost 2400 degrees Fahrenheit

When the NASA probe Pioneer 10 passed by Jupiter in 1973, it sent scientists back some puzzling readings taken from the planet’s upper atmosphere. Until then, most planetary researchers believed that Jupiter’s upper reaches would be pretty cold, considering how far the gas giant is from the sun’s warming rays. And Jupiter isn’t the only …

Conservationists in South Africa have been injecting rhino horns with red dyes and toxins to prevent poaching. The mixture renders the horn completely useless to those trying to sell it commercially and is also toxic for human consumption.

Officials in South Africa are taking the grave situation of the vanishing rhino population into their own hands — infusing their horns with red dye and toxins to ensure that poachers can’t sell the valuable body parts.

The reason why we view neanderthals as hunched over and degenerate is that the first skeleton to be found was arthritic.

1. You’re pretty much a Neanderthal. While it’s been more than 5 million years since we parted ways with chimps, it has been only 400,000 since human and Neanderthal lineages split. 2. If you’re Asian or Caucasian, your ancestors interbred with Neanderthals as recently as 37,000 years ago, when they crossed paths in Europe. 5. …

Bees dance to each other in the hive to tell each other where to find good pollen. The angle of the dance is the angle relative to the sun, the tempo of dance is the distance, the duration of dance is the quality of the pollen, and the dancer hands out free samples to whoever’s watching!

Food sources of lower quality will produce fewer, shorter, and less vigorous dances; recruiting fewer new foragers. The round dance is used for food sources 25-100 meters away from the hive or closer. Bees elicited into foraging after a round dance fly out of the hive in all directions searching for the food source they …

At 24 years old, Isaac Newton was sent home from school to avoid the bubonic plague. During this time, he invented calculus.

It’s also the reason Sir Isaac Newton and other innovators were prompted to create some of the most dreaded mathematical equations that we know today. To understand the need Newton felt for more precise mathematics, you first need a brief understanding of what math existed before he came along and changed everything. It is worth …

Physicist Nikola Tesla once paid an overdue hotel bill with a box containing a working model of his ‘death beam‘, warning employees never to open it because of the danger. They hid the box & when it was discovered years later & opened, found to contain old (harmless) electrial parts.

In the years following the tragedy, Tesla (the son and grandson of Serbian Orthodox priests) began seeing visions of the air around him “filled with tongues of living flame.” As an adolescent Tesla learned to exercise his willpower to control the visions, but in later life he would spend much of his time feeding and, …

In the 1880s, the Harvard Observatory director was frustrated with his staff, and would say “My Scottish maid could do better!” So, he hired his Scottish maid. Williamina Fleming ran a team for decades, classified tens of thousands of stars, & discovered white dwarfs and the Horsehead Nebula.

Williamina Fleming Williamina Paton Stevens Fleming (May 15, 1857 – May 21, 1911) was a Scottish astronomer. During her career, she helped develop a common designation system for stars and cataloged thousands of stars and other astronomical phenomena. Among several career achievements that advanced astronomy, Fleming is noted for her discovery of the Horsehead Nebula …
