Are Single People Happier in Their Sex Lives?

A recent exploration into the sexual lives of single and married individuals reveals that the notion of singles having more fun in the bedroom may be misleading. Research indicates that while sexual frequency among married couples has declined—averaging 55 times a year compared to 59 for singles—this does not necessarily mean that single people are enjoying better sex lives. A 2021 report from the Center for Researching and Understanding Sexual Health found little difference in sexual activity between single and married individuals, with both groups reporting similar frequencies. Factors such as age and sexual orientation play significant roles, with younger adults and those identifying as bisexual or homosexual being more sexually active. Ultimately, the quality of sexual experiences, rather than mere frequency, is crucial for satisfaction, suggesting that both singles and couples can find fulfillment in their intimate lives, regardless of their relationship status. sources

"One-Minute Video Explains Mercury's Airplane Ban"

A recent one-minute video has shed light on the reasons behind the ban on mercury thermometers aboard commercial flights. While many items are prohibited for obvious safety reasons, the restriction on mercury-filled thermometers may seem peculiar. The primary concern is the risk of amalgam corrosion, a chemical reaction that occurs when mercury comes into contact with exposed aluminum, a common material in aircraft construction. This reaction can lead to significant damage, as even small amounts of mercury can initiate a self-propagating corrosion process, potentially compromising the structural integrity of the aircraft. The video illustrates the dangers of this interaction, emphasizing that the ban is in place to prevent any risk of damage that could arise from a broken thermometer during a flight. Thus, the prohibition is a precautionary measure to ensure passenger safety and aircraft integrity. sources

3I/ATLAS Object Alters Course, Possibly Loses Mass, NASA Reports

New observations of the interstellar comet 3I/ATLAS, first detected by astronomers on July 1, indicate that it may have lost a significant amount of mass during its recent close approach to the Sun. This third known interstellar visitor, following 1I/ʻOumuamua and 2I/Borisov, has exhibited unusual behaviors, including a rare anti-tail and extreme iron-to-nickel abundance ratios. Following its perihelion, or closest approach, 3I/ATLAS has shown non-gravitational acceleration, suggesting it lost over 13% of its mass due to outgassing, a common phenomenon for comets. Recent observations from October 31 to November 4 revealed a fivefold increase in brightness, indicating ongoing cometary activity. As telescopes worldwide resume monitoring, scientists hope to glean insights into the comet's origins and the interstellar medium, furthering our understanding of these cosmic wanderers. sources

"Massive 'Living Fossil' Discovered in Mississippi Floodplains"

The Mississippi River floodplains are home to the alligator gar, a remarkable fish species known scientifically as *Atractosteus spatula*, which is the largest of its kind in North America. Dr. Solomon David, an expert on these freshwater giants, recently reported capturing a record-breaking alligator gar measuring 240 centimeters (7 feet 10 inches) and weighing approximately 136 kilograms (300 pounds). This fish, likely between 50 to 90 years old, was tagged and released as part of a study on river floodplain restoration, highlighting the species' role in assessing ecological connectivity. Alligator gars are opportunistic predators, thriving in diverse habitats, but face threats from environmental changes and overharvesting. As "living fossils," they exhibit slow evolutionary rates, with recent studies revealing hybridization between alligator and longnose gars, showcasing their unique genetic history. David's research aims to deepen understanding of these ancient fish and their ecological significance. sources

Why Doesn't Flying Against Earth's Rotation Speed Up Flights?

Confusion has arisen regarding why flights do not speed up when flying against the Earth's rotation, particularly among some flat Earth proponents. A recent post questioned how a plane flying west at 300 mph does not reach its destination significantly faster, given that the Earth rotates eastward at approximately 1,400 mph. However, this misunderstanding stems from a flawed grasp of physics. When a plane takes off, it carries the same forward momentum as the Earth due to inertia, meaning it does not simply hover in place as the ground spins beneath it. Additionally, the atmosphere moves with the Earth, preventing the extreme wind speeds that would otherwise affect flight times. In fact, flights tend to be quicker when flying east due to jet streams, which are influenced by the Earth's rotation and atmospheric conditions. Thus, while the Earth's spin does impact flight indirectly, it does not allow for the simplistic notion of faster travel against its rotation. sources

Earth's Top Predators: Animals That Are Nearly Invincible

Saltwater crocodiles, among Earth's apex predators, exemplify the power dynamics of the animal kingdom. Captured in a striking 2017 helicopter video, one crocodile was seen effortlessly carrying a freshwater crocodile in its jaws, highlighting its dominance in the food chain. Apex predators, defined as those without natural enemies, play crucial roles in maintaining ecosystem balance. While saltwater crocodiles can grow over 20 feet long, their survival is increasingly threatened by human activities such as poaching and habitat destruction. Other apex predators, including lions, tigers, bald eagles, and polar bears, face similar challenges, with their populations dwindling due to environmental pressures. Notably, orcas have emerged as formidable hunters, even targeting great white sharks. As these apex species navigate their precarious existence, the impact of human interference looms large, threatening the delicate balance of nature. sources

Hippos Lingered in Europe 80,000 Years Longer Than Expected

New fossil evidence has revealed that hippopotamuses thrived in central Europe much later than previously believed, surviving until approximately 47,000 to 31,000 years ago, well into the last ice age. Previously, it was thought that these mammals went extinct around 115,000 years ago due to unfavorable climatic conditions. The findings, based on the analysis of 19 hippo fossils from the Upper Rhine Graben in Germany, indicate that these hippos belonged to the same species as modern African hippos (_Hippopotamus amphibius_) and exhibited low genetic diversity, suggesting a small, isolated population. Researchers emphasize that this discovery challenges existing assumptions about the extinction timeline of hippos in Europe and highlights the need for further examination of other fossil records attributed to the last interglacial period. The study, published in *Current Biology*, underscores the complexity of ice age environments across Europe. sources

Chernobyl's dead trees and leaves remain intact

Nearly three decades after the Chernobyl disaster, research reveals that radioactive contamination continues to hinder ecological processes in the region, particularly affecting decomposers like microbes and fungi. A study led by Timothy Mousseau from the University of South Carolina found that litter mass loss in contaminated areas was 40% lower compared to less affected sites, with the forest floor accumulating thicker layers of dead leaves. The research involved placing 572 mesh bags filled with dry leaves in various locations around Chernobyl, revealing that the most contaminated sites had significantly less decomposition. While soil invertebrates contributed to some breakdown, the study highlighted that microbes and fungi were crucial for litter decomposition. This disruption in nutrient recycling may explain the slower growth rates of trees in the area, as essential elements remain locked in undeterred plant material. The findings were published in the journal *Oecologia*. sources

Trees Use Rivers to Travel Between Amazon and Atlantic Forests

A groundbreaking study suggests that tree species from the Amazon rainforest have been continuously migrating to the Atlantic rainforest by utilizing rivers as a "hidden highway," rather than only during historical wetter periods. Researchers from the University of Edinburgh and the Royal Botanic Garden Edinburgh analyzed the genetics of 164 _Inga_ tree species, revealing 16 to 20 instances of successful migration from the Amazon to the Atlantic, while only one or two species moved in the opposite direction. This ongoing dispersal highlights the interconnectedness of these ecosystems, which transcend national borders and have significant implications for conservation efforts. With only 20% of the Atlantic rainforest remaining intact, experts stress the importance of protecting both the forests and the rivers that facilitate this vital ecological connectivity. The findings, published in the journal *Proceedings of the Royal Society B: Biological Sciences*, underscore the need for long-term habitat preservation strategies. sources

Voyager to Reach One Light-Day from Earth on Nov 13, 2026

In a historic milestone for space exploration, NASA's Voyager 1 is set to become the first human-made object to reach a distance of one light-day from Earth, expected to occur on November 13, 2026. Launched in 1977, Voyager 1 has traveled approximately 25.9 billion kilometers (16 billion miles) and is currently about 169.5 astronomical units from our planet, with signals taking nearly 23 hours and 30 minutes to reach it. At its speed of 61,198 kilometers per hour, the spacecraft will take over a year to achieve this light-distance. After this point, Voyager will continue its journey through the Oort Cloud and eventually encounter the star Gliese 445 in about 40,000 years. Despite the vast distances, Voyager's mission will persist until it runs out of power in the early 2030s, leaving it to drift through interstellar space, carrying the Golden Records as a testament to humanity. sources
