Scientists have discovered a method to convert white fat cells into beige ones in mice, a breakthrough that could pave the way for new weight-loss treatments for humans. White fat cells, which store energy and contribute to weight gain, can be transformed into beige fat cells, which burn calories, by suppressing a protein called KLF-15. This protein is found in higher concentrations in beige and brown fat cells. The research team, led by Brian Feldman, found that eliminating KLF-15 in white fat cells prompted their conversion to beige cells. Further investigation revealed that KLF-15 interacts with the Adrb1 receptor, crucial for energy balance, suggesting that drugs targeting this receptor may be more effective for weight loss than those aimed at the previously studied Adrb3 receptor. While the research is still in its early stages, it holds promise for future obesity treatments, as noted in the study published in The Journal of Clinical Investigation. 
Published: Nov 10 2025, 5 pmeznews.inBlue Origin, the private space company founded by Amazon's Jeff Bezos, is preparing to launch its New Glenn rocket on Wednesday, carrying two NASA orbiters, the Escape and Plasma Acceleration and Dynamics Explorers (ESCAPADE), to Mars. This mission marks a significant step for Blue Origin, which aims to contribute to NASA's exploration efforts, including a future lunar rover mission. The launch, initially scheduled for November 9, was postponed due to adverse weather conditions, specifically cumulus clouds, which pose a risk of lightning strikes during liftoff. Blue Origin has announced a new launch window from 2:50 PM to 4:17 PM EST on November 12, with a live webcast available for viewers. The New Glenn rocket, designed for partial reusability, will attempt a vertical landing of its booster after deployment of the twin spacecraft, which will study Mars' magnetic field and atmospheric interactions.
Published: Nov 10 2025, 10 pmeznews.inThe world is home to some truly disturbing parasites, each with unique and gruesome life cycles. The tongue-eating louse, *Cymothoa exigua*, invades fish, replacing their tongues with itself after sucking their blood. Meanwhile, the guinea worm, *Dracunculus medinensis*, inflicts excruciating pain on humans as it emerges from the skin, having grown up to 80 cm inside the body. Fungi like *Ophiocordyceps* manipulate ants into seeking ideal growth conditions before killing them and sprouting from their heads. Horsehair worms compel crickets to leap into water, ensuring their own survival, while parasitoid wasps, such as *Glypatapanteles*, turn caterpillars into guardians for their larvae. Lastly, filarial worms, transmitted by mosquitoes, can lead to debilitating conditions like elephantiasis in humans. These examples highlight the bizarre and often horrific strategies employed by parasites to thrive in their hosts.
Published: Nov 07 2025, 7 pmeznews.inNew research suggests that Neanderthals may not have faced a sudden extinction around 40,000 years ago, but rather were gradually absorbed into the _Homo sapiens_ gene pool through extensive interbreeding. Mathematical models indicate that rather than being outcompeted or wiped out, Neanderthals intertwined with our ancestors over millennia, leading to a dilution of their distinct genetic lineage. This challenges more dramatic theories of their demise, such as genocide or resource competition, and posits that repeated cycles of _Homo sapiens_ immigration contributed to their genetic assimilation. The study highlights that traces of Neanderthal DNA persist in modern humans, particularly among those of European descent, influencing various health conditions. This raises philosophical questions about species existence and extinction, suggesting that if Neanderthal genes remain active in us, they are not entirely gone. The findings are detailed in the journal *Scientific Reports*.
Published: Nov 10 2025, 9 pmeznews.inPrzybylski's Star, or HD 101065, has emerged as a leading candidate for the presence of advanced alien civilizations due to its unusual chemical composition. Discovered in 1961, this A-type star exhibits peculiarities, including the presence of rare elements like promethium, which has no long-lived isotopes, suggesting a continuous production process. While some scientists propose that these elements could result from interactions with a neutron star companion or decay from undiscovered heavy elements, others speculate that they may indicate intelligent life. The idea posits that advanced civilizations might intentionally introduce manufactured elements into stars as a beacon for other intelligent beings. Although these theories remain speculative, the star's enigmatic nature continues to intrigue astronomers, prompting further investigation into its origins and the potential for extraterrestrial life.
Published: Nov 10 2025, 1 pmeznews.inA bald eagle found dead in Highland Lake, Maine, met an unusual fate after a necropsy revealed it was killed by a loon chick. The eagle was discovered floating face down in July 2019, prompting wildlife biologist Danielle D’Auria to investigate after a local reported hearing disturbances the previous night. The investigation ruled out human involvement, as no bullet fragments were found, but a puncture wound on the eagle's chest matched the beak of the deceased loon chick found nearby. D’Auria noted that while loons are known to use their sharp beaks defensively, it is rare for a juvenile to take down such a formidable predator. This incident highlights the increasing conflicts between bald eagles and loons, as eagle populations recover and predation on loons rises. The case is reportedly the first of its kind in the area, raising questions about the dynamics of these avian interactions.
Published: Nov 10 2025, 11 ameznews.inThe ubiquitous calorie count on food labels, often perceived as a standard measure of daily energy needs, is rooted in flawed data and misconceptions. The figure of 2,000 calories, mandated by the FDA, was not derived from scientific research or nutritional guidelines but rather from self-reported dietary surveys, which are notoriously unreliable. Studies have shown that individuals tend to underreport their calorie intake, leading to a misleading benchmark. In fact, the average daily calorie consumption is higher, with men needing about 3,050 calories and women around 2,400 to maintain stable body weight. The FDA's choice of 2,000 calories was influenced by public feedback, aiming for a memorable and simplified guideline rather than an accurate reflection of nutritional needs. Consequently, this figure is often inadequate for most adults, highlighting the complexities of individual dietary requirements and the challenges of establishing universal nutritional standards.
Published: Nov 06 2025, 6 ameznews.inA recent analysis of data from the National Electronic Injury Surveillance System (NEISS) reveals a troubling trend in the United States: an increase in emergency room visits due to mishaps involving sex toys. Over the past decade, the number of incidents has risen, with vibrators being the most commonly "stuck" items, often found in rectums, which accounted for nearly 70% of cases. Experts attribute this rise to the growing normalization of sex toys, driven by celebrity endorsements and improved accessibility through online shopping. Notably, men are more frequently admitted to ERs for these incidents, although younger women also show a peak in cases. Dr. Carol Queen emphasizes the need for better sexual education, particularly regarding anal play, to prevent such accidents. As society becomes more open about sexual health, experts advocate for comprehensive education to ensure safety and enjoyment in sexual exploration.
Published: Nov 10 2025, 2 ameznews.inThe goliath frog (_Conraua goliath_), reigning as the world's largest frog, can grow up to 75 centimeters (29.5 inches) long and weigh between 2.7 to 3.3 kilograms (6 to 7.3 pounds). Native to the rainforests of Cameroon and Equatorial Guinea, these impressive amphibians inhabit areas near fast-flowing rivers and streams. Unlike other frogs, goliath frogs lack vocal sacs, making them relatively silent, though they can produce a whistling sound. Notably, male goliath frogs exhibit unique nesting behavior, constructing ponds from rocks to protect their eggs and tadpoles from predators. Despite their remarkable adaptations, goliath frogs are now classified as endangered, facing threats from habitat loss due to agriculture and logging, as well as hunting for their meat, which remains a popular delicacy. Although they have existed for approximately 250 million years, their future is uncertain as their populations continue to decline.
Published: Nov 06 2025, 9 ameznews.inNew observations of the interstellar comet 3I/ATLAS, which was 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 comet, the third known interstellar visitor after 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. The latest observations, conducted from October 31 to November 4, reveal a fivefold increase in brightness, indicating ongoing cometary activity. As astronomers continue to monitor this intriguing object, further studies may provide insights into its origins and the interstellar medium from which it came.
