?? The Domestication of Modern Horses: A 4700-Year-Old Journey ??
Paleogenetic studies have revealed fascinating insights into the domestication of modern horses, tracing their origins back to approximately 4700 years ago. Researchers analyzed the DNA of 475 ancient horses and discovered that the ancestors of all modern domesticated horses were first tamed around 2700 BCE. This pivotal event took place in the Pontic-Caspian steppe.
Key genetic evidence for this domestication comes from extensive regions of homozygosity in horse genomes, indicative of inbreeding and deliberate human selection. Early breeders likely aimed to cultivate horses with desirable traits. By the end of the 3rd millennium BCE, these ancient horse breeders managed to reduce the generational interval significantly, from 7.4 years to 3.5 years, possibly to meet the rising demand for horses.
The widespread distribution of horses beyond the Pontic-Caspian steppe began around 2200 BCE. However, another potential candidate for the title of first horse breeders is the Botai culture from the Eneolithic era in northern Kazakhstan. Archaeological evidence from the 4th millennium BCE, including artifacts resembling horse enclosures and possible traces of mare's milk in pottery, suggests early horse management practices.
While new research supports this theory, it also shows no signs of inbreeding among Botai horses. Nonetheless, a reduction in generational intervals in this population suggests that the Botai people might have engaged in horse breeding, albeit not on a large scale.

Bees Returning Home with Their Shopping Bags!
Bees come home with packages after their shopping trips! These industrious insects have special “pollen baskets” on their hind legs, which look and function like tiny pockets. These structures are held in place by bristles and hairs, making them perfect for carrying pollen.
By the way, we owe plant biodiversity to bees. They have proven to be highly effective pollinators, outcompeting other insects in this vital role.

Phobos: One of Mars’ Intriguing Moons
Phobos, one of the two moons orbiting Mars, presents a fascinating subject for scientific exploration. This celestial body orbits at a distance of 6,006 kilometers from the Martian surface and is gradually drawing closer to the planet. Over time, this proximity will lead to significant changes in its orbit, offering unique opportunities for study.

Moonbows, also known as lunar rainbows, are optical phenomena that occur under the influence of moonlight.
A distinctive feature of moonbows is their less vivid colors due to relatively weak illumination. However, long-exposure photographs can capture these subtle colors.

Breakthrough in Diabetes Treatment in China
In a groundbreaking medical achievement, doctors in China have successfully cured a patient of Type 2 diabetes using cell therapy. The 59-year-old man had battled the disease for 25 years, facing severe complications. Most of the insulin-producing islets in his pancreas had failed, leaving him dependent on daily insulin injections.
In July 2021, the patient underwent a cell transplantation procedure. Remarkably, his body began producing insulin independently, and within a year, he was able to discontinue his blood sugar-regulating medications entirely. This pioneering treatment offers new hope for millions living with diabetes.

"Chang'e-6" Lands on the Far Side of the Moon
The Chinese probe has successfully landed and is now set to collect soil samples from the far side of our satellite. If all goes well, approximately 2 kilograms of soil samples will be brought back to Earth.
The sample collection will take two days, and the return of "Chang'e-6" is scheduled for June 25. If successful, China will become the first country to deliver soil samples from the far side of the Moon to Earth.

Jupiter: Earth's Cosmic Protector
This animation shows how Jupiter protects Earth!
The gas giant's gravity keeps most asteroids and space rocks away from our planet. It also intercepts long-period comets that intrude into the inner solar system from its outer edges.
However, Jupiter sometimes sends space objects our way. In 1770, thanks to Jupiter, the famous Lexell's Comet passed just two million kilometers from Earth. The comet arrived from the distant reaches of the solar system three years earlier and passed close to Jupiter, which adjusted its orbit and sent it toward Earth. Fortunately, the comet missed us, made two passes around the Sun, and in 1779, approached Jupiter again, which then flung it out of our solar system.

Real Stars in the Universe of "Dune"
The "Dune" universe references many real stars.
For instance, the home planet of House Harkonnen, Giedi Prime, is part of the 36 Ophiuchi system. Contrary to Villeneuve's film, there are no black stars there; 36 Ophiuchi consists of three orange dwarfs.
House Atreides' home, Caladan, orbits Delta Pavonis. This once sun-like star has nearly exhausted its hydrogen and is transforming into a red giant. In reality, House Atreides would need to leave this system to find a new home.
The primary planet of "Dune," Arrakis, also orbits a real star—Canopus. This white-blue giant is 8-10 times more massive than the Sun, 70 times its radius, and over 10,000 times more luminous. At around 30 million years old, it's quite young compared to our Sun.
However, more massive stars die faster. Canopus has already depleted its hydrogen fuel and is now undergoing helium fusion. Its future is uncertain; it may become a red giant and then a white dwarf, like our Sun, or it might explode as a supernova. Fortunately, Canopus is very far from us.

Sea Urchin Waiting for the Tide
A sea urchin in anticipation of the tide... and it seems the wait won't be long. When the tide is far off, sea urchins usually bore themselves into rocks, burrow into the sand, or cover themselves with pieces of shells and seaweed. They do all this to avoid being spotted by predators.

? T-Lymphocytes: Our Body’s Natural Defense Against Cancer
Cytotoxic T-lymphocytes, also known as T-killer cells, play an essential role in our immune system by targeting and destroying our body’s own cells that have been compromised. Their targets include cells infected with intracellular parasites such as viruses and certain bacteria, as well as cancerous cells. This ability makes T-killer cells a crucial component of the body’s natural defense system against cancer.

? Super Flare Alert: Quadruple Solar Flares Captured on the Sun
NASA’s Solar Dynamics Observatory witnessed a spectacular display from the Sun, capturing not one but four simultaneous solar flares. These flares erupted from three sunspots and a large magnetic filament—a plasma loop interconnecting these spots. Termed as sympathetic flares, this extraordinary quartet event on April 23rd is dubbed a “super sympathetic” occurrence.
Expect magnetic storms and potential auroras, with the most likely dates for magnetic disturbance being April 25th-26th.

? Exciting Lunar Exploration Update ?
A private company, Intuitive Machines, is set to launch a new lunar module, μNova, by the end of this year. This innovative 35 kg module is equipped with dual cameras, a radiometer (LRAD), and a neutron spectrometer (PLWS), all supported by an autonomous navigation system. μNova is designed for precise landings, capable of handling slopes up to ten degrees and low-light conditions.
The μNova’s mission will focus on geological surveys at the lunar south pole, specifically between Shackleton and de Gerlach craters. It aims to analyze hydrogen presence in the regolith, temperature differences in sunlit vs. shaded areas, and the thermal properties of the surface.
After landing, μNova will undergo system checks and perform a series of leaps—starting with a 20-meter test jump, escalating to 100 meters, and potentially reaching up to 300 meters. The mission includes up to 5-6 jumps, exploring the rim and the permanently shadowed regions of Marston crater.

Meta, led by CEO Mark Zuckerberg, is advancing its technology to create can interpret brain signals for controlling digital tools. Unlike similar technologies like Elon Musk’s Neuralink, which require surgical implantation, Meta’s devices are non-invasive and worn on the wrist. These devices utilize electromyography (EMG) to translate neural signals into commands for other devices. This innovative approach, currently in internal testing at Meta, aims to eventually integrate with augmented reality platforms like Meta’s Ray-Ban smart glasses to enhance digital interactions through sophisticated, multi-modal AI technologies. This marks a significant step in bridging the gap between human cognitive functions and machine operations, potentially transforming how we interact with our digital environments.
