Scientists reveal how fruit flies navigate turbulent air to trace odor sources

Researchers have uncovered how fruit flies are able to track scents through turbulent, unpredictable airflows to locate their source. The study found that the insects rely on a combination of a sharp sense of direction and short-term memory to follow invisible ribbons of odor. Rather than following a continuous scent trail, fruit flies must piece together fragmented smell signals carried by chaotic air currents. This navigation strategy allows them to effectively zero in on the origin of a scent despite the disrupted nature of how smells travel through the environment.

Ancient 'Ghost' Lineage in Africa Found Embedded in Human DNA

Scientists have identified genetic traces of an ancient, unknown human lineage in the DNA of modern humans. This so-called 'ghost' lineage has no living descendants and is distinct from Neanderthals or other known archaic humans. The group interbred with ancestors of modern humans at some point in prehistoric Africa, leaving a measurable imprint on our genomes. Researchers made the discovery by analyzing patterns in contemporary human DNA that could not be explained by known ancestral populations. The finding suggests human evolutionary history in Africa was more complex and interconnected than previously understood.
