The deathly scent, lunar phobia, and other science news
The article discusses various intriguing scientific stories that might have slipped under the radar in the past week. One intriguing discovery is related to the color of blue cheese. Blue cheeses like Roquefort, Gorgonzola, and blue Stilton get their unique blue hue from fungi, and scientists have managed to alter the genes responsible for this color, resulting in blue cheeses that are red, green, or white while still tasting similar to the original blue cheeses. The study found that altering the color of the cheese affected people's perceptions of its flavor, with volunteers rating differently colored strains as milder, fruity, or tangy.
Another fascinating study explores the behavior of mammals in tropical forests during moonlit nights. Researchers analyzed camera trapping data and discovered that around 16% of mammal species exhibited "lunar phobia," avoiding moonlight, while 3% displayed "lunar philia," actively seeking out moonlit areas. This behavior sheds light on how lunar cycles influence the behavior of forest-dwelling mammals.
Another news are on the impact of female scent on male mice. A study revealed that the smell of a female mouse can accelerate a male mouse's reproductive aging, leading to a reduced lifespan and limiting the number of litters he sires. This phenomenon highlights the powerful influence of pheromones on behavior and lifespan in animals.
In addition, or certain species within the Dasyuridae marsupial family, mating becomes a frenzied and ultimately fatal endeavor. Scientists have grappled with the reasons behind this unique form of sexual suicide: a selfless act to reduce competition for offspring, or a consequence of detrimental genetic mutations? A new study reveals that the answer lies in intense competition for females. Examining 52 Dasyuridae species across diverse regions, researchers observed a link between this extreme behavior and short, resource-dependent mating seasons. Females mate with multiple partners, forcing males into a desperate race to father offspring. The most reckless and prolonged mating efforts appear to maximize reproductive success, even at the cost of the male's life. These ill-fated males endure copulation sessions lasting an average of 9 hours, far exceeding the 4-hour norm in species with less constrained mating seasons. Evolutionary pressures have endowed them with larger-than-average testicles in support of this extreme strategy.
Furthermore, researchers investigated the genetic and chemical basis of the delectable flavor of sweet oranges. By using machine learning and expert tasters, they identified key chemical compounds responsible for the unique "orange flavor" and linked seven compounds to a previously unknown gene. This discovery could pave the way for creating disease-resistant citrus varieties without compromising their signature sweetness.
Another study challenges the conventional understanding of the Golgi apparatus in animal cells. While the Golgi apparatus is typically depicted as ribbonlike structures in vertebrate cells, researchers discovered similar ribbony Golgi in a broader range of animals, suggesting its early evolution predates vertebrates. This finding could provide valuable insights into the evolutionary origins and functions of this vital cellular organelle.
Finally, the news of a newly discovered species of green anaconda, known as the world's heaviest snake, advancements in diagnosing sepsis through DNA analysis, and Florida being the lightning strike capital of the United States, are noteworthy.
