A 2012 study has revealed that humans can identify age based solely on body odor, a capability previously thought to be limited to animals. Researchers collected body odors from various age groups by having participants wear T-shirts with underarm pads for five nights, which were then sniffed by volunteers aged 20 to 30. The findings suggest that older individuals emit distinct odors that younger people perceive as neutral rather than unpleasant, challenging stereotypes about "old person smell." This phenomenon, known as kareishu in Japan, may serve evolutionary purposes, such as aiding in mate selection. The study's senior author, Johan Lundström, noted that while the exact mechanisms behind these odors remain unclear, they could help humans identify biological age and avoid illness. Further research is needed to explore the implications of these findings, which were published in the journal PLOS One. 
Published: Jun 28 2025, 1 ameznews.inHuman skin is intricately patterned with what are known as Blaschko lines, a phenomenon first described by German dermatologist Alfred Blaschko in 1901. These lines, which map the pathways of skin cell migration during embryonic development, become visible under specific conditions and do not cross the body's anterior midline. They form distinctive shapes, including a V-shape at the back and wavy lines along the limbs and face. Various skin conditions, such as lichen striatus and genetic disorders like incontinentia pigmenti, can cause lesions that align with these lines, illustrating a form of cutaneous mosaicism where different genetic cell populations coexist. A rare variant, chimerism, occurs when two fertilized eggs merge, leading to individuals with distinct genetic traits, including varied pigmentation. Despite myths suggesting that these lines can be seen under UV light by cats, no scientific evidence supports this claim.
Published: Jun 30 2025, 7 pmeznews.inThe upcoming film adaptation of Andy Weir's _Project Hail Mary_, set for release on March 20, 2026, presents a chilling scenario where humanity faces extinction due to a mysterious dimming of the Sun. The protagonist, Ryland Grace, portrayed by Ryan Gosling, awakens on a spaceship with fragmented memories, tasked with addressing this dire cosmic threat. The film explores the concept of global dimming, a phenomenon where various factors reduce sunlight reaching Earth, which could theoretically lead to catastrophic climate changes, including an ice age. While some scientists have raised concerns about geoengineering solutions to combat climate change, the academic consensus suggests that the Sun's luminosity is relatively stable, with only minor fluctuations observed during its 11-year sunspot cycle. As the film's narrative unfolds, it raises questions about the potential consequences of such a solar crisis, making it a compelling blend of science fiction and real-world scientific inquiry.
Published: Jun 30 2025, 8 pmeznews.inThe shoebill, a striking bird native to East Africa, stands at 1.5 meters tall and boasts a massive, knife-edge beak measuring up to 24 centimeters. Its unusual appearance has led to various misclassifications over the years, but DNA evidence now suggests it is closely related to pelicans. Known for its bizarre behavior, the shoebill prefers to remain motionless for long periods, only to launch a swift attack on prey like lungfish and even crocodiles using its formidable beak. Despite its impressive hunting skills and longevity of up to 35 years, the shoebill faces significant threats from habitat loss, pollution, and illegal hunting, with an estimated 5,000 individuals remaining in the wild. Conservation efforts in Zambia's Bangweulu Wetlands are underway to protect this unique species, highlighting the importance of sustainable practices for both wildlife and local communities.
Published: Jun 30 2025, 5 pmeznews.inResearchers from the University of Virginia School of Medicine and the National Institutes of Health have identified a previously unknown organelle within human cells, named the "hemifusome." This discovery, likened to finding a new recycling center in the cell, was detailed in a recent study published in *Nature Communications*. The hemifusome plays a crucial role in managing how cells package and process materials, particularly through vesicles, which function as delivery vehicles within the cell. Study author Seham Ebrahim emphasized that this organelle acts as a "loading dock" for vesicles to connect and transfer cargo, a process previously unrecognized. Understanding the hemifusome's function could provide insights into genetic disorders linked to cellular cargo handling. Ebrahim noted that this discovery opens new avenues for research into cell health and potential treatments for complex genetic diseases, marking a significant advancement in cellular biology.
Published: Jun 30 2025, 6 pmeznews.inSix months after their birth, two genetically modified wolves, Romulus and Remus, along with their sister Khaleesi, are thriving under the care of Colossal Biosciences. Weighing over 90 pounds, the six-month-old brothers exhibit traits reminiscent of their extinct dire wolf ancestors, while Khaleesi, at 35 pounds, is slightly smaller but still larger than typical gray wolves. Critics argue that these animals are not true dire wolves, as they are hybrids created from gray wolf and dire wolf DNA, with 20 genetic modifications. Experts emphasize that true de-extinction would require cloning, which is currently unfeasible due to DNA preservation issues. Despite the controversy, Colossal's work aims to enhance genetic diversity in endangered species, such as red wolves, and potentially revive the northern white rhino through advanced genetic techniques. While ethical debates persist, these efforts represent significant strides in conservation science.
Published: Jun 30 2025, 4 pmeznews.inNASA's Voyager missions, launched in 1977, carry a unique artifact known as the Golden Record, designed to communicate the essence of humanity to potential extraterrestrial life. This gold-plated LP features a diverse collection of sounds, greetings, and music, encapsulating the human experience. The record includes everyday sounds like laughter, a dog barking, and natural noises, alongside 90 minutes of music ranging from Bach to Chuck Berry's "Johnny B. Goode." A map of pulsars on the cover helps any finders locate Earth. Greetings in 55 languages, including Mandarin and Arabic, convey messages of peace and curiosity, with the English greeting delivered by Carl Sagan's son. Despite the unlikelihood of contact, the Golden Record serves as a time capsule of human culture, reflecting our hopes and aspirations as we venture into the cosmos, now nearly one light-day away from Earth after 48 years of travel.
Published: Jun 29 2025, 4 pmeznews.inSkinwalker Ranch, located in western Uintah County, Utah, has become a focal point for paranormal enthusiasts, featuring tales of UFOs, cryptids, and mysterious animal mutilations. Named after Navajo legends of shape-shifting witches, the ranch gained notoriety after the Sherman family, who purchased it in 1994, reported a series of bizarre encounters, including sightings of werewolf-like beings and strange lights. They sold the property in 1996 to UFO enthusiast Robert Bigelow, whose National Institute for Discovery Science (NIDS) also failed to provide conclusive evidence of the phenomena. In 2016, the ranch was acquired by real estate investor Brandon Fugal, who allowed a History Channel crew to film investigations, yet no substantial proof has emerged. Skeptics, including Robert Sheaffer, argue that the supposed phenomena are likely illusory, noting that the previous owners experienced none of the reported strangeness, raising questions about the ranch's authenticity.
Published: Jun 30 2025, 8 ameznews.inIn a surprising twist to space exploration history, two Russian steppe tortoises became the first living beings to orbit the Moon, achieving this feat on September 18, 1968, aboard the Soviet spacecraft Zond 5. This mission predated NASA's Apollo 8 by several months, yet it remains less celebrated due to the absence of human crew members. The tortoises, launched on September 14, were part of a scientific study to assess the effects of space travel on living organisms, accompanied by worms, flies, and seeds. After a four-day journey, Zond 5 successfully returned to Earth, landing in the Indian Ocean on September 21, with the tortoises in good health despite some weight loss. This milestone marked a significant moment in the Space Race, showcasing the Soviet Union's efforts to reclaim its position in the competition against the United States.
Published: Jun 28 2025, 12 ameznews.inFor nearly 48 years, NASA's Voyager 1 and 2 have explored the Solar System and interstellar space, but they were not the first missions designed for such journeys. That distinction belongs to Pioneer 10 and 11, launched in the early 1970s, which became the first spacecraft to image Jupiter and Saturn and to achieve escape velocity from the Solar System. Notably, Pioneer 10 carried the iconic Pioneer plaque, a message intended for extraterrestrial life, featuring depictions of humans and the Solar System's location. Despite their earlier launch, the Pioneers are now outpaced by the Voyagers, with Pioneer 10 last communicating in 2003 and Pioneer 11 in 1995. Both probes exhibited a mysterious deceleration known as the "Pioneer anomaly," later attributed to thermal effects from their onboard systems. These pioneering missions laid the groundwork for future explorations, influencing subsequent missions like Voyager and New Horizons.
