Discover the MPO stain, essential for acute myeloid leukemia diagnosis. Learn its purpose, procedure, and how it differentiates myeloid from lymphoid cells. Myeloperoxidase (MPO) is a lysosomal enzyme found in the azurophilic granules of neutrophils,...

Arneth Count classifies neutrophils (N1–N5) by nuclear lobes. Detects left shift (infections) vs. right shift (anemia). Normal ranges for clinicians. Arneth count, developed by Joseph Arneth, is a hematological method that classifies neutrophils into...

New research reveals that Ice Age hunter-gatherers used a sophisticated system of geometric signs to store and share information across generations, potentially laying the groundwork for future written languages. Humans possess a unique capacity to...

Learn what MCH measures, the normal range, causes of high and low MCH, and how it helps diagnose iron deficiency, B12 deficiency, thalassemia, and other blood disorders. If you’ve ever looked at a CBC report and wondered what is MCH in a blood test,...

ancestry—that underpins Tibetan adaptation to low‑oxygen conditions, as reported in a 2014 Nature study. Excavated human bones in room 2 of Old Lady Spider Cave ©Nature While the new Ladakh data emphasize demographic history rather than physiological...

(490 pounds), comparable to a large domestic pig. The fossil includes articulated vertebrae, ribs, forelimb and hindlimb bones, and foot elements, making it one of the most complete Triassic dinosaur specimens from Zimbabwe. Researchers estimate the...

aim to detect wear patterns that could confirm these functional hypotheses. To date, no organic material—such as human bones, animal remains, or plant residues—has been recovered from the cave, a gap that limits direct insight into the diet and daily...

groups. Radiocarbon Results Reset the Boomerang’s Age The revised age stems from radiocarbon analysis of human and animal bones recovered from the same layer as the boomerang. The study, published in PLOS ONE, places the associated material at roughly...

implements. The fact that many of these fractures were obscured by paraffin wax—used by early excavators to stabilize the bones—explains why they eluded detection for so many decades. Beyond the Royal Inner Circle The identity of those buried in these...

A strange Sahara dinosaur challenges Spinosaurus theories, revealing a frightening new hunting method. A team led by University of Chicago paleontologist Paul Sereno has announced a new spinosaurid species, Spinosaurus mirabilis, whose anatomy suggests...

New Brazilian fossil snake shows early snakes split habitats: some went underground, others thrived elsewhere, shedding light on snake origins. A new fossil of the extinct stem snake Tametara mirim provides an unprecedented glimpse into the brain...

A family vacationing on the New Jersey coast has discovered a rare, prehistoric megalodon tooth, uncovering a remarkable piece of ancient history. A routine family getaway to the New Jersey coastline turned into a monumental paleontological discovery...

A head-to-head test of lightweight computer vision models reveals high accuracy in detecting hidden dental remnants. A tiny left-behind piece of a tooth root can trigger hidden bone infections or ruin a dental implant, but dentists frequently miss them...

Archaeologists have unearthed a groundbreaking, previously undocumented human history hidden deep beneath Tanzania’s famous wildlife paradise. Archaeologists working in Tanzania’s Serengeti National Park have unearthed a trove of historical evidence,...

71.4 and 65.0 million years ago. Whether through the crystalline interiors of the Anhui fossils or the delicate embryonic bones in Jiangxi, these discoveries continue to refine our understanding of the diversity and reproductive strategies of dinosaurs...

fossilized vertebrae are rare and provide a valuable window into the dimensions of individual animals. In this case, the bones were not uncovered by a fresh dig; they had lain unnoticed on a museum shelf for years. Rediscovered Megalodon Vertebrae...

zhelestids dates back nearly 40 years. Because these animals are frequently found as isolated teeth or fragmented bones, researchers were forced to make broad evolutionary claims based on their bunodont molars. These low, rounded cusps looked strikingly...

elsewhere. However, without associated fossils, this remains an educated hypothesis. The Taphonomic Mystery The absence of bones at the site is not entirely surprising to experts in taphonomy, the study of how organisms decay and become fossilized....

a rare and compelling glimpse into the past, challenging what we know about human history without the need for tools or bones. Deep within the Nefud Desert of northern Saudi Arabia, wind-swept sands have revealed a remarkable window into the prehistoric...
