US achieves first moon landing in over 50 years

In a historic moment, the United States has successfully landed a spacecraft on the Moon for the first time in over 50 years, marking the first instance of a private company achieving this feat. Intuitive Machines' lander, Odysseus, touched down near the Moon's south pole, with flight director Tim Crain confirming the successful transmission from the lunar surface. Despite some technical glitches with Odysseus' lasers, NASA's intervention saved the day, allowing for data and images to be transmitted back to Earth. This achievement signifies a significant milestone in space exploration, with NASA administrator Bill Nelson emphasizing the importance of commercial partnerships in advancing space missions. With other countries also making successful lunar landings recently, the future of space exploration looks promising, with more missions planned for the coming year. sources

Reasons for waking up at 3am or 4am nightly

The modern world's sharp political divides and rampant misinformation have led to the creation of the term "reality gap." While disagreements persist on various issues, one thing most can agree on is that waking up at 3 or 4 am is less than ideal. Stress is a common factor behind these early awakenings, making individuals more aware of their sleep disruptions. Factors like erratic schedules, doomscrolling, and poor sleep hygiene can also contribute to waking up in the night. Sleep experts recommend maintaining a consistent sleep schedule, avoiding screens before bed, and addressing stressors to improve sleep quality. Keeping a to-do list may help ease anxiety-related awakenings, but if sleep problems persist for more than three months, seeking help from a specialist, such as Cognitive Behavioral Therapy, is advised. sources

Map shows location opposite side of Earth if dug through

An interactive map has been created to show where you would end up if you dug straight through the Earth from various locations around the world. Contrary to popular belief, people in the USA would not end up in China, and those in the UK would not reach Australia. The map reveals that most European countries lead straight to the ocean, with the only safe destination being central Spain. Similarly, those in the USA would also end up in the sea, with the closest dry land being near Fort McMurray in Canada. The map allows users to enter their location and find their antipode point, with major cities listed as well. So before attempting to dig through the Earth, it is advised to check the map to see where you would actually end up. sources

Brain waves predict angry dreams, study finds

A recent study published in the Journal of Neuroscience has identified a pattern of brain activity that predicts feelings of anger during dreams. Researchers from the University of Turku in Finland and the University of Skövde in Sweden monitored the brain activity of 17 participants during REM sleep and found that those who reported more negative emotions in their dreams, such as anger, had more alpha-band brain activity in the right frontal cortex. This asymmetrical brain activity, known as frontal alpha asymmetry, has previously been linked to anger in waking states. While the study had limitations, such as a small sample size and participants sleeping in a lab setting, it sheds light on the neurological basis of anger dreams and the processing of negative emotions during sleep. Lead author Pilleriin Sikka suggests that dreams may reflect our waking emotions and experiences, and processing negative emotions in dreams could be beneficial for overall well-being. sources

First-ever photos of hidden corridor in Great Pyramid revealed

A hidden corridor inside the Great Pyramid of Giza, sealed for over 4,500 years, has been revealed for the first time by a team using muon tomography. The corridor, located above the King's Chamber, was confirmed as a "big void" and explored with an endoscope camera by officials at the Egyptian ministry of antiquities. The purpose of the corridor and the void it leads to remains unknown, with theories ranging from relieving pressure inside the pyramid to potentially leading to a secret burial chamber of King Khufu. While hopes of finding the remains of Khufu may be slim, Egyptian archaeologist Zahi Hawass believes the corridor may lead to "something important," hinting at possible discoveries in the near future. sources

Early hominids had diverse diet, not just Paleo

Reconstructions of human evolution often oversimplify our ancestors' behavior, including their diet. The popular Paleo Diet, inspired by the Stone Age, encourages a hunter-gatherer lifestyle, but the reality of early hominid diets is more complex. Research on the origins of hominid diet from 6 to 1.6 million years ago reveals a varied menu including tubers, fruits, animals, and more. Optimal foraging theory helps predict the diet of early hominids based on energetic value and availability of resources. Contrary to the belief that our ancestors were great hunters, evidence suggests they were omnivorous and opportunistic foragers. The complexity of our shared history challenges simplistic views of early hominid ecology, highlighting the adaptability and flexibility that allowed our ancestors to thrive and spread across the globe. sources

China's New Stealth Aircraft Uses Plasma Technology

China has developed a new stealth aircraft that utilizes plasma technology to make military jets less visible on radar. Traditional stealth technology focuses on materials and design to reduce reflection and emission of light and sound, but Chinese scientists have proposed a new approach involving plasma, the fourth state of matter. Plasma, when ionized, can absorb electromagnetic waves such as radar, making the aircraft invisible. Chinese researchers have successfully tested two approaches using radioactive material or electricity to create plasma around specific portions of the aircraft. This technology could potentially be applied to various aircraft designs without the aerodynamic drawbacks of traditional stealth aircraft. Plasma stealth has also been used in Russian missiles, showing promise for future military applications. sources

Definition of scallops

Scallops, often enjoyed as a tasty appetizer, are marine bivalve mollusks with around 400 species in the family Pectinidae. Their shells come in various colors and shapes, housing a white adductor muscle and orange coral, both edible. Surprisingly, scallops possess over 200 eyes with a unique system of concave mirrors, allowing them to see in peripheral and narrow views simultaneously. These filter feeders consume phytoplankton and small organisms, inhabiting saltwater environments worldwide. Some species, like the Atlantic sea scallop, can be found at depths of 30 to 91 meters in the Northwest Atlantic Ocean. Female scallops can produce millions of eggs annually, released into the water column for fertilization. With their ability to swim away from predators by snapping their shells, scallops prove to be fascinating creatures beneath the ocean's surface. sources

US Men Peeing Incorrectly, Says Urologist

A recent survey conducted by data analytics firm YouGov revealed that men in the US are not peeing correctly, with only 10 percent sitting down to urinate compared to Germany where most men do so. The survey found that sitting down to pee is more common in Germany and Sweden, with a nearly 40 percent gap between the US and Germany. According to a urologist, sitting down to pee is better for men's health, as it helps empty the bladder more efficiently and can prevent complications such as urinary tract infections and bladder stones, especially in men with enlarged prostates. Studies have shown that sitting down to pee is particularly beneficial for men with urination problems, emphasizing the importance of adopting this practice early on. sources
