New analysis of Cassini data reveals how Saturn’s moon Enceladus launches frozen ocean fragments into space, providing fresh clues in the search for life. Enceladus, the small, icy moon orbiting Saturn, may be inadvertently acting as a sophisticated...

grave. However, as the excavation deepened, the structure revealed itself to be a complex, hand-dug gallery. Recovered fragments of late medieval pottery and a metal horseshoe solidified the timeline, proving that the passage was a much later addition...

notable, as most locations outside of world-renowned sites like Lascaux or Altamira typically yield only sparse, weathered fragments. First recorded in 1912 (left), the rock markings were later dismissed as a natural phenomenon before being reconsidered...

steppe ecosystem. The site reveals clear signatures of human intervention. Microscopic analysis of ribs and other bone fragments shows sharp, distinct cut marks consistent with flint tools. Investigators also recovered eight stone implements, including...

While the cuirass—a protective chest plate worn by heavy cavalry—has captured the most attention, the team also unearthed fragments of ornate park sculptures, antique metal door fittings, and various weaponry components dating back over a century....

of defensive walls, and a stone-paved thoroughfare connecting the lower city to the southern gate. The recovery of pottery fragments and amphorae dating to the Early Iron Age strongly suggests that the site was not left to total desolation, but rather...

freshly ejected ice grains from Enceladus’s ocean: Analysis of Cassini measurements identified previously unseen organic fragments in fresh plume grains, expanding the known chemical diversity emerging directly from Enceladus’s subsurface ocean. (Nature...

solar system’s early, volatile years, Earth and Mars were subjected to intense bombardment, creating a mechanism for rock fragments—and potentially biological material—to travel between the two worlds. Susanne Schwenzer, a professor of planetary...

Scutaru, the accessible seams are largely depleted. Only a handful of locals still scour the terrain, hoping to find small fragments in ponds following heavy rainfall. The area is now subject to strict preservation efforts, including a 2.52-hectare...

shell remains from Cerro de San Vicente ©Springer Nature Unusual species also played a role in these ceremonial events. Fragments of burned freshwater turtle shells, identified as Emys orbicularis and Mauremys leprosa, were found exclusively in contexts...

on neutralizing the two ways HBV persists in the body: as stable, chromosome-like structures known as cccDNA and as fragments of viral genetic material integrated into the patient’s own genome. These hidden reservoirs allow the virus to remain...

sorted through some 10,000 sand grains collected from Japan’s Motoujina Peninsula. As scientists continue to analyze these fragments, they are uncovering a new perspective on the intersection of human destruction and rare material formation, proving...

The presence of two anchors and related equipment indicates the ship may have been at anchor when it was lost. Two shoe fragments – Credit: GR Dijkstra / LaKD M-V “I try not to speculate,” Grabowski said, emphasizing the need for scientific rigor over...

and iron handles, intended to automate the composition of books. By manipulating these cranks, students could shuffle word fragments to generate sequences that might, in theory, form coherent thoughts on philosophy, law, or science. The device was...

A recent study published in the Oxford Journal of Archaeology provides the first comprehensive look at the surviving fragments, which largely consist of archival photographs, news clippings, and oral histories gathered from those involved in the...

factors, platelets help maintain hemostasis. Unlike other blood cells, platelets lack a nucleus and instead consist of fragments derived from large bone marrow cells called megakaryocytes. These small, biconvex discs, typically measuring 2–3 µm in...

when combined with hemoglobin. The life span of R.B.C. is 120 days. The spleen helps in trapping the old cells and broken fragments. The dead cells are disposed of by macrophages present in the liver, bone marrow, and spleen. The hemoglobin of dead...
