Why Do Some People Wake Up at 3 or 4 AM?

Many people find themselves waking up at 3 or 4 a.m., a phenomenon affecting approximately one in three individuals, particularly since the pandemic. Sleep experts attribute this to heightened awareness of natural awakenings during light sleep, often exacerbated by stress and anxiety. Cognitive therapist Greg Murray notes that while stress doesn't directly cause these awakenings, it makes individuals more conscious of them. Factors such as irregular schedules, excessive screen time, and poor sleep hygiene can also contribute. To mitigate these disturbances, experts recommend establishing a consistent sleep schedule, engaging in morning light exposure, and maintaining a to-do list to manage worries. If sleep disruptions persist for over three months, seeking professional help, such as Cognitive Behavioral Therapy, may be necessary to address potential insomnia. Understanding the body's sleep cycles and addressing underlying stressors can significantly improve sleep quality. sources

Man Injects Magic Mushrooms; They Grow in His Blood

A 30-year-old man, referred to as "Mr. X," was hospitalized after injecting a homemade "mushroom tea" made from magic mushrooms, leading to severe health complications. His family brought him to the emergency department due to confusion, following his cessation of prescribed bipolar medication and subsequent mood swings. Mr. X had researched the therapeutic effects of psilocybin, the active compound in magic mushrooms, but opted to inject the tea rather than consume it orally. After the injection, he developed jaundice, nausea, and organ failure, ultimately requiring intensive care. Alarmingly, cultures taken from his blood revealed that the fungus was growing within his veins. While the exact impact of the fungal infection on his mental state remains uncertain, medical professionals emphasized the need for public education on the dangers of misusing drugs outside of prescribed methods. sources

Tasmanian Tigers' Genetics May Have Predestined Their Extinction

New research has shed light on the extinction of the Tasmanian tiger, or thylacine (_Thylacinus cynocephalus_), suggesting that genetic factors may have played a significant role alongside human hunting and competition with dingoes. Once native to Australia, Tasmania, and New Guinea, the thylacine's population dwindled to around 5,000 by the early 1800s, with the last known specimen dying in 1936. Researchers utilized palaeogenomic data to identify the loss of four crucial genes—SAMD9L, HSD17B13, CUZD1, and VWA7—over a span of 13 million to 1 million years ago, prior to human interference. These genes are linked to immune function and overall species fitness, and their loss may have compromised the thylacine's health and adaptability. The study highlights the importance of genetic diversity in understanding extinction and offers a framework for future research into the evolutionary processes affecting both extinct and extant species. sources

New Method Could Reveal Pre-Big Bang Events in Einstein's Equations

Researchers at the Foundational Questions Institute are leveraging complex computer simulations to explore the enigmatic moments surrounding the Big Bang, a phenomenon where conventional physics falters. Time, as we understand it, did not exist during this event, and traditional equations fail to provide clarity. By employing numerical relativity—an approach developed in the 1960s to study black hole mergers and gravitational waves—scientists aim to push beyond current scientific limits. Professor Eugene Lim from King’s College London expressed enthusiasm for using this method to investigate the Big Bang and the subsequent period of Cosmic Inflation, which is crucial for explaining the uniformity of the universe. While inflation remains an "effective theory" needing a more fundamental basis, numerical solutions could unveil new insights into cosmic conditions and potentially support theories like the cyclical universe or multiverse hypotheses. Despite its challenges, advancements in computational power are propelling this research forward. sources

Men's Behavior Changes Around Women With Erect Nipples, Study Finds

A study conducted by psychologists at the State University of New York at Oswego has revealed intriguing insights into how heterosexual men and women perceive women with nipple erections. In the first part of the research, participants rated images of women, some with erect nipples and some without, on various emotional and physiological states. Results indicated that both men and women projected more positive emotions onto women with erect nipples, with men particularly associating them with "sexy emotions." The follow-up study, published in *Evolutionary Behavioral Science*, explored whether these perceptions influenced male behavior. It found that heterosexual men were significantly more willing to assist women with erect nipples, especially in situations requiring close interaction, believing them to be more deserving of altruism. In contrast, heterosexual women did not share this perception and were less inclined to include women with erect nipples in their social circles. The study highlights potential biases, as all images featured "attractive" women. sources

Over 7 Billion to Witness Next Week's Total Lunar Eclipse

Skywatchers are gearing up for a spectacular Blood Moon event, set to occur during the evening of September 7-8, depending on your timezone. This total lunar eclipse will see the Moon transition from a darkened state to a striking crimson hue as it passes through the Earth's shadow. The entire spectacle will last 3 hours, 29 minutes, and 24 seconds, with visibility extending to most of Asia, parts of East Africa, and Western Australia, while a broader audience across Africa, Europe, and Brazil will witness at least a partial eclipse. Remarkably, up to 60% of the global population, or around 7 billion people, could view the full eclipse, making it a record-breaking event. The phenomenon occurs due to the alignment of the Sun, Earth, and Moon, with the Moon taking on a red tint as sunlight filters through Earth's atmosphere. sources

Another Ancient Skull Identified as Denisovan

A prehistoric skull discovered in China in the 1970s, known as Dali Man, is likely a Denisovan, according to a new study published in the Proceedings of the National Academy of Sciences. Previously debated as either _Homo erectus_ or an archaic _Homo sapiens_, the skull exhibits key traits associated with Denisovans, a sister lineage to modern humans first identified through DNA from a finger bone in Siberia's Denisova Cave in 2010. Researchers analyzed gene regulation patterns to identify 32 physical traits linked to Denisovans, finding that Dali Man matched 15 of 18 traits. This study follows the recent identification of another ancient skull, Dragon Man, as Denisovan, and suggests that a 1921 skull from Zambia, Broken Hill Man, may represent a common ancestor of Denisovans and Neanderthals. The findings could aid in classifying other ambiguous hominin fossils, addressing the so-called "Muddle in the Middle" in human evolution. sources

Science-Backed Flirting Technique That Often Works

A study by psychologists at the Norwegian University of Science and Technology has identified the most effective flirting techniques for men and women, based on research involving heterosexual college students from the US and Norway. Participants rated 40 flirting methods for their effectiveness in short- and long-term relationships. For women seeking short-term flings, signals of sexual availability, such as physical closeness, were deemed most effective. In contrast, men benefited from a combination of physical tactics and social engagement, including smiling and complimenting. For men pursuing long-term relationships, demonstrating generosity and commitment was key. Interestingly, humor emerged as a universally effective tactic, particularly for men in long-term contexts, while women appreciated being acknowledged for their humor. The findings suggest that starting with smiling and eye contact can enhance flirting success, as detailed in the journal Evolutionary Psychology. sources

"Only One: The Live-Birthing Western Nimba Toad"

The Western Nimba toad (_Nimbaphrynoides occidentalis_), native to the Mount Nimba region of West Africa, is unique among amphibians for giving birth to live, fully developed young after a nine-month gestation period. This reproductive strategy, which involves a distinctive birthing posture, is believed to be an adaptation to the harsh environment of the region, where water is scarce. The species is critically endangered, with its habitat recognized as a UNESCO World Heritage Site due to its rich biodiversity, including other endemic species. Conservationists are now urging the Guinean government to impose a five-year moratorium on iron-ore mining in the area, citing the potential irreversible damage to this ecological haven. The call for action is supported by several international organizations, emphasizing the need to protect both the Nimba toad and the broader ecosystem that sustains local communities. The government has yet to respond to these concerns. sources
