Owls have the widest neck rotation range among animals. This remarkable feature stems from the unique articulation of their spine with the skull. Unlike mammals, which typically have two occipital condyles (spherical ends of a bone that fit into a cavity in another bone to form a joint), owls possess only one.
Additionally, birds have a long, flexible neck containing anywhere from 11 to 23 movable vertebrae. An owl's head can swivel approximately 270 degrees in each direction, allowing for a total rotational range of one and a half full turns. This extraordinary neck flexibility is not just a peculiar trait; it's a critical adaptation that allows owls to have a nearly unobstructed view of their surroundings, an essential asset for a predator that hunts primarily at night.

Winds in Antarctica
Temperature is far from the only challenge awaiting the brave souls at the South Pole. Here blow the strongest and most persistent winds on the planet, reaching speeds of 322 km/h (with an average of about 240 km/h)! Moreover, these winds blow almost year-round, hardly ever subsiding. Nowhere else in the world will you encounter such harsh weather conditions.
However, it’s almost always sunny here: due to the cold, the air is very dry (it has the lowest relative humidity on the planet), making this place have the most intense solar radiation on Earth.

In our Solar System, there are numerous asteroids rich in valuable elements that are highly coveted by humanity. Therefore, it's imperative that we develop technologies for their industrial exploitation!💎
Let's explore the top three most valuable asteroids:
Psyche is located in the main asteroid belt. This 240-kilometer wide asteroid is rich in metals, including nickel and iron, and also contains gold and platinum. However, recent reports suggest that Psyche might predominantly consist of rocky material. We will obtain accurate information in 2026 following NASA's mission dedicated to its study.
The asteroid Asporina is covered with olivine, a bright green mineral. Its presence in this iron-stone meteorite classifies Asporina as a rare type of pallasite. Meteorites of this class are highly valued among collectors due to their uniqueness and high cost.
Gaspra is composed of various metals and their oxides, giving the asteroid's surface a fascinating mix of hues.

An artificial intelligence algorithm successfully developed a catalyst for extracting oxygen from Martian meteorites in just six weeks.
This task, if performed by a human using standard chemical screening (where each full cycle takes five hours to find an optimal catalyst from the same composition of Martian rocks), would have taken two thousand years.
The project is being spearheaded by scientists from China and presented by @science

Unveiling the Most Water-Repellent Surface Ever!
Scientists have crafted a surface dubbed as the most water-repellent ever. By employing a liquid-like coating, water rolls off this surface at angles 500 times shallower compared to other superhydrophobic materials. This novel technology, creating ‘liquid-like surfaces’, presents a game-changer, especially in automotive, marine, and aerospace sectors, where repelling water is crucial. The innovative surface behaves like a lubricated platform, ensuring water slides right off, setting a new standard in superhydrophobic materials .

Unraveling the Mystery of Petrichor: The Scent of Rain
Petrichor arises from oils released by plants, absorbed by soil, and then liberated into the air during rainfall. The compound geosmin, produced by soil bacteria, adds to this unique scent, detectable by humans at very low levels. Light rains amplify petrichor, as gentle droplets coax more aroma from the soil.
Petrichor embodies nature’s complexity, a dance between earth, water, and life. Next time rain freshens the air, remember the fascinating interaction behind that beloved scent.

🚀 Breathtaking First Look at the Contents of NASA's Bennu Asteroid Sampler! 🌌
After an arduous wait of over three and a half months since the OSIRIS-REx spacecraft triumphantly returned them to Earth, we've finally been granted the first high-resolution images of the precious contents from the Bennu asteroid sampler container. The unveiling was delayed by two stubborn fasteners that kept the sampler lid secure but were successfully opened on January 10.
On January 19, NASA unveiled these long-anticipated visuals, giving us a glimpse into the pristine remnants of our solar system's history. These samples, delicately collected from the 4.5-billion-year-old asteroid Bennu, are not just rocks and dust; they represent a narrative of our cosmos, potentially holding secrets about the origin of water and life on Earth.
Stay tuned as @science dive deeper into this cosmic treasure trove and unravel the mysteries of the universe! 🌠

🔬 Breaking Through in Neuroscience: Unveiling the Reality of Zoom Fatigue
Recent groundbreaking research has neurophysiologically confirmed what many have experienced in the wake of increased virtual interactions post-COVID-19: Zoom fatigue is real!
🧠 The study, published in Scientific Reports, utilized EEG and ECG data to compare the effects of video conferences and face-to-face interactions. Results showed that 50-minute video conferences led to significantly greater fatigue than in-person sessions of the same duration.
📊 This marks a pivotal step in understanding the neurophysiological impacts of our increasingly digital world, particularly the effects of prolonged video-based communication. René Riedl and Gernot Müller-Putz, leading the study, emphasize the importance of this understanding for individual well-being, interpersonal relationships, and organizational communication.
🔍 The researchers propose that a holistic view of the psychological and physiological mechanisms involved is essential to develop strategies to mitigate the harmful effects of videoconference fatigue.
