A few very large, round impressions could have been made by sauropods, the long-necked giants. The researchers are careful here. Footprints rarely preserve enough detail to name a specific dinosaur. Instead, the tracks show general body types and...

one of physics’ weirdest ideas does not need quantum mechanics at all. Crystals are easy to understand. You see them everywhere, in salt, sugar, gemstones, even metals. Their atoms line up neatly, repeating the same pattern again and again across space....

and self-control. However, they constantly exchange information. Scientists describe this using ideas from network science. There are two important concepts here: Local efficiency and clustering: How tightly nearby brain regions communicate with each...

satellites, navigation systems and power networks that modern life relies on. Deploying a Fleet to Reinforce the Magnetosphere Earth’s magnetosphere acts as a giant magnetic bubble that deflects charged particles from the Sun. When a powerful coronal...

research. The answer, as of mid-2026, is that the evidence is striking and biologically plausible but not yet causal. Here’s what the data actually show. At BioScience, we’ve been tracking the intersection of vaccine immunology and neurodegeneration...

related guides in this series cover MCV, MCHC, hemoglobin, and ferritin with the same evidence-first approach you’ll find here. This article walks through what MCH measures, what normal adult values look like, what high and low results indicate, and...

the gas giant KELT-9 b pushes the limits of chemistry. Data from the Spitzer Space Telescope indicate that temperatures here are extreme enough to rip hydrogen molecules apart, turning them into individual atoms before they reform on the planet’s dark...

relies on high-energy X-rays combined with a 2mm copper filter to mitigate beam-hardening—a common distortion effect where dense clay disrupts clear imaging. Sophisticated reconstruction software then processes the raw data, allowing historians to...

to Lingering Mysteries Despite the richness of the find, many questions remain unanswered. “Who were the people buried here? What was the cause of their death? Why were the bodies often cast into deep features like storage pits or wells? What role did...

13 years of imaging from the Mayall and Blanco telescopes into a single map that spans three‑quarters of the celestial sphere and catalogues nearly four billion objects. The effort, carried out under the auspices of the NSF’s NOIRLab, merges 263 407...

TLC The total leukocyte count (TLC) per microliter is calculated using the following formula: TLC/μl = (Nw × Cd × Cv) ÷ NLS Where: Nw = number of WBCs counted Cd = correction for dilution (typically 20) Cv = correction for volume (10) NLS = number of...

of Biological Evolution of Man! 1. Theory of Eternity This is an orthodox theory. It believes that some organisms were there from the very beginning of the Universe. Those organisms still exist and will be continued in future in addition to some new...

tests are quite simple to perform while others are complicated and may require sophisticated equipment. The tests presented here are among the easier ones that are utilized in major clinical laboratories around the world. These tests are ordered...

canals (b) In current canals: These are narrow canals. These are covered inside by epethelial cells. They show some openings here and there called prosopyles. (c) Radial canal: The body wall is folded. In these foldings radial canals are present at...

to the blood in the labyrinth. The urine is collected and it flows into the bladders. The excretory fluid also comes here from the renal sac. The urine is passed out through the ureters and renal apertures. Osmoregulation: Water enters the body...

Once ingested, food travels through the esophagus and enters the first chamber of the stomach, known as the "foregut." Here, initial fermentation and digestion take place before passing into the small intestine. The small intestine is where the majority...
