The Black Death was an evolutionary arms struggle between humanity and one of the most clever pathogens in history, not only a mediaeval horror. The bacterium causing the plague, Yersinia pestis, evolved to guarantee its survival rather than merely killing millions. Now, revolutionary studies show how the plague changed its genetic code to become less ...
Scientists have finally uncovered the molecular mechanism that gives green bush crickets their distinctive foliage-like color. A newly identified protein, dibilinoxanthinin (DBXN), binds two distinct pigments—a blue bilin and a yellow lutein—to create the insect’s emerald-green hue. This discovery sheds light on how bush crickets achieve their remarkable camouflage, helping them blend seamlessly into their ...
From the bones of individuals living 6,000 years ago deep in Colombia’s highlands, a genetic mystery has emerged. Their DNA tells a different story than any other one without clear ancestors or descendants in the modern society. These prehistoric people unearthed on the Bogotá Altiplano challenge our understanding of American population distribution. Whales: they were ...
New research has revealed that female earwigs may use their forceps as weapons when competing for mates, challenging previous assumptions that only males evolved these structures for combat. Scientists from Toho University found that female earwigs exhibit exaggerated forceps growth, similar to males, suggesting that sexual selection may have influenced both sexes. This discovery broadens ...
For decades, donated eggs or sperm have been the mainstay of infertility treatments, leaving many hopeful parents without a genetic relationship to their offspring. But suppose the secret to producing a biologically related child was something as common as skin rather than hidden in reproductive cells? Researchers are getting closer to a radical breakthrough whereby ...
Long praised by athletes for its muscle-building properties, creatine is now generating waves for a completely different reason: possible Alzheimer’s disease prevention. A ground-breaking pilot study implies that widely available in health stores, creatine monohydrate could help Alzheimer’s sufferers have better cognitive ability. Although the results are preliminary, they create an intriguing new path in ...
A groundbreaking genetic study has uncovered a Neanderthal population in France that remained completely isolated for 50,000 years. Unlike other Neanderthal groups, which often exchanged genes with neighboring populations, this group remained genetically and culturally separate. The discovery raises new questions about the role of isolation in Neanderthal extinction and challenges long-held assumptions about their ...
A groundbreaking study has revealed that supplementing vasopressin, a hormone linked to social behavior, may improve social cognition in rhesus monkeys without increasing aggression. Researchers at Florida Institute of Technology, in collaboration with Stanford University and the University of California, Davis, explored how vasopressin affects low-social monkeys, offering insights into potential autism treatments. How Vasopressin ...
Romulus and Remus, two snow-white canids with powerful shoulders and wide jaws, look like something out of myth. In a way, they are. Born in the fall of 2024 through cutting-edge genetic engineering, they are the first living examples of what scientists believe to be true dire wolves in over 10,000 years. The species once ...
