Over the past few centuries, the global human population has surged from one billion in 1804 to seven billion by 2017, raising fears of potential famine due to resource scarcity. While some theorists, like the Malthusians, predicted that population growth would self-correct through mass deaths, advancements in agriculture have enabled food production sufficient to sustain 10 billion people. However, distribution issues have led to starvation. In the 1970s, researcher John B. Calhoun conducted a controversial experiment with mice in a "utopia" where all needs were met, leading to a breakdown in social structures and violent behaviors, ultimately resulting in extinction despite ample resources. Calhoun's findings, termed "behavioral sink," suggest that without fulfilling social roles, populations may collapse. While his conclusions resonated with concerns about urban overcrowding, recent critiques argue that the experiment's design may not accurately reflect human societal dynamics, emphasizing the importance of resource control over mere availability. 
Published: Mar 31 2025, 9 pmeznews.inA recent study has revealed nine rivers and lakes in the Americas that defy traditional hydrological principles, showcasing unique bifurcations where waterways split into multiple channels without returning to the main flow. Notable examples include the Echimamish River in Canada, which flows in both directions due to its flat terrain and beaver dams, and the Casiquiare River in Venezuela, which connects the Orinoco and Amazon Basins, described as a "hydrologic equivalent of a wormhole." Other intriguing cases include the Wayambo River in Suriname, which can flow either east or west depending on rainfall, and North Two Ocean Creek in Wyoming, allowing fish to migrate between the Atlantic and Pacific watersheds. The study emphasizes the diversity of these hydrological anomalies, highlighting the need for further exploration of Earth's complex water systems. The findings are published in the journal *Water Resources Research*.
Published: Apr 02 2025, 8 pmeznews.inSpaceX has made history by launching four astronauts into a pole-to-pole orbit, a trajectory not previously undertaken by humans. The Fram2 mission, commissioned by cryptocurrency billionaire Chun Wang, aims to conduct 22 scientific experiments, including the first X-ray in space and studies on human health in microgravity. Polar orbits, typically avoided for human missions due to increased radiation exposure and health risks, are beneficial for global Earth coverage, allowing satellites to observe every inch of the planet. Most rockets are launched from west to east to take advantage of the Earth's rotational speed, which reduces fuel costs. However, this mission's unique trajectory required more propellant, making it economically challenging. The crew is expected to spend 3-5 days in space before returning, where they will assess their ability to perform tasks without assistance after varying durations in orbit.
Published: Apr 02 2025, 11 pmeznews.inConcerns are mounting over public safety in the United States following significant job cuts initiated by the Trump administration, with Health Secretary Robert F. Kennedy Jr. overseeing the dismissal of approximately 10,000 employees from the Department of Health and Human Services. Key agencies affected include the Food and Drug Administration (FDA), which is set to lose 3,500 staff responsible for food and drug safety, and the Centers for Disease Control and Prevention (CDC), facing a reduction of 2,400 jobs that jeopardizes vital health programs. The National Institutes of Health (NIH) will also see 1,200 positions cut, impacting crucial research efforts. Critics argue that these drastic reductions will exacerbate existing health issues in a country already grappling with high healthcare costs and declining life expectancy. As the cuts unfold, questions remain about the long-term implications for public health and safety in the U.S.
Published: Apr 02 2025, 8 pmeznews.inA new study proposes a scientific explanation for near-death experiences (NDEs), often described as sensations of leaving the body and encountering a bright light. Researchers suggest that these phenomena may be an evolutionary response to life-threatening situations, termed the Neurophysiological Evolutionary Psychological Theory Understanding Near-death Experience (NEPTUNE). The model posits that NDEs occur when oxygen levels in the brain drop, leading to increased neuronal activity in key areas, which may trigger vivid hallucinations and feelings of peace due to neurotransmitter surges. The study indicates that individuals more prone to dissociation or daydreaming are likelier to experience NDEs, as are those with a tendency for REM intrusion. However, the authors acknowledge that while NEPTUNE sheds light on some aspects of NDEs, it does not fully explain phenomena like precognition. The findings are detailed in the journal *Nature Reviews Neurology*.
Published: Apr 02 2025, 9 pmeznews.inWhen transporting helium balloons in a car, an intriguing phenomenon occurs during acceleration and braking. Unlike ordinary balloons filled with air, which are pushed backward when the car accelerates, helium balloons move forward. This counterintuitive behavior is due to the principles of buoyancy and density. As the car accelerates, the air inside the vehicle shifts backward, creating a buoyant force that pushes the lighter helium balloon forward. Conversely, when the car brakes, the air moves toward the front, causing the buoyant force to push the helium balloon backward. This effect highlights the unique properties of helium, which is less dense than the surrounding air, and illustrates the fascinating dynamics of fluid behavior in motion.
Published: Apr 02 2025, 1 ameznews.inAn underwater vehicle named "Boaty McBoatface" has made headlines after recovering a long-lost camera from Loch Ness, originally deployed in a 1970s quest to capture images of the elusive Loch Ness Monster. The camera, which was designed to take photos when a bait line was disturbed, was discovered 180 meters underwater during a test mission by the UK’s National Oceanography Centre (NOC). Remarkably, it remained intact after 55 years. Although the developed film did not reveal any images of Nessie, the recovery marks a significant moment in the ongoing fascination with the legendary creature, first reported in the 7th century. The camera will be displayed at The Loch Ness Centre in Drumnadrochit. NOC engineers emphasized the importance of such missions in advancing marine robotics and understanding ocean ecosystems, particularly in the face of climate change and human impact.
Published: Apr 02 2025, 7 pmeznews.inThe US Government has unveiled a new collection of UFO footage, revealing a mix of unidentified aerial phenomena (UAPs) and explanations that clarify some sightings as ordinary objects. The Pentagon's All-domain Anomaly Resolution Office (AARO) emphasized that investigations have not confirmed any UAPs as extraterrestrial technology, stating that most incidents stem from misidentifications. Among the newly released videos, some remain unexplained, including footage captured by US Navy F/A-18 jets, while others were identified as commercial aircraft after thorough analysis. AARO noted that one particular sighting, initially deemed mysterious, was later attributed to a sensor artifact from video compression. The release aims to provide transparency amid ongoing public interest in UAPs, although the majority of cases have been resolved as non-anomalous.
Published: Apr 02 2025, 4 pmeznews.inIn 1962, French geologist Michel Siffre embarked on a groundbreaking experiment in the Scarasson cave of the French Alps, intending to study a glacier for just 15 days. However, he extended his stay to 63 days, living in complete darkness and isolation, devoid of any timekeeping devices. This unique experience led Siffre to discover that the human body possesses an internal clock independent of the sun's rhythm, significantly altering his perception of time. His findings revealed that, without external cues, his sleep-wake cycle extended from 24 hours to as much as 48 hours. Despite facing skepticism and criticism for his unconventional methods, Siffre's work laid the foundation for the field of human chronobiology, influencing research on sleep patterns, jet lag, and even cancer development. His experiments garnered attention from military and space agencies, highlighting the relevance of his findings in understanding human biology in extreme conditions.
Published: Apr 02 2025, 5 pmeznews.inColossal Biosciences has unveiled the "Colossal woolly mouse," a genetically engineered rodent designed to mimic traits of the extinct woolly mammoth, as part of their ambitious plan to resurrect the species by 2028. By targeting seven specific genes linked to mammoth characteristics, the team has created mice with orange, wavy fur up to three times longer than that of typical mice, alongside altered lipid metabolism. This innovative approach allows for rapid testing of genetic edits, as mice have a much shorter gestation period than Asian elephants, the mammoth's closest living relatives. The project aims not only to explore de-extinction but also to restore ecological balance by reintroducing traits that could positively impact modern ecosystems. Colossal's efforts represent a significant step toward understanding and potentially reviving extinct species, with the ultimate goal of enhancing biodiversity and environmental health.
Published: Apr 02 2025, 12 pmeznews.inThe Faroe Islands, a self-governing archipelago of around 750 islands, are home to the optical illusion of Lake Sørvágsvatn, which appears to float above the sea. Located on Vágar Island, this lake, also known as Leitisvatn, is the largest in the archipelago, covering 3.4 square kilometers and sitting just 30 meters above sea level. Photographers often capture the lake from angles that create the illusion of it hovering high above the ocean, despite its actual elevation. The nearby Bøsdalafossur waterfall adds to the dramatic scenery as it cascades into the sea. Historically, the island played a strategic role during World War II, with a British airfield established to monitor German naval activity. Today, visitors can hike to viewpoints like Trælanípa cliff to witness the lake's mesmerizing optical illusion, which continues to captivate nature enthusiasts.
