Scientists probe Antarctica’s Blood Falls, the mysterious red water, revealing clues about ancient life trapped beneath the ice for millions of years. Red-colored runoff emerging from the base of Taylor Glacier in Antarctica has turned out to be more...

Scientists find cold‑adapted yeast in Ötzi the Iceman, bake sourdough with it, and show the ancient mummy still harbors a dynamic microbial ecosystem. More than five millennia after the Alpine discovery of Ötzi the Iceman, scientists have identified an...

Explore the importance of sputum tests, and learn microbiological examination procedures. Learn the role of sodium chloride and propylene glycol in sputum induction. A sputum test, also known as sputum examination or sputum analysis, is a laboratory...

Genetics is the study of genes, heredity, and genetic variation in living organisms. It is generally considered a field of biology, but it intersects frequently with many of the life sciences and is strongly linked with the study of information...

Scientists are working to build living cells from scratch. Are we close to mastering synthetic biology and unveiling the origins of life in the lab? The Race to Build Synthetic Life: Are Scientists on the Verge of a Breakthrough? Billions of years ago,...

A detailed reconstruction of ancient ocean chemistry suggests that long-term changes in seawater calcium closely tracked atmospheric carbon dioxide as Earth cooled over the last 50 million years. Over the last 50 million years, Earth slowly changed...

Rare Illinois fossils upend a long‑standing evolutionary theory, showing an unexpected route taken by Earth’s earliest four‑legged animals. A striking assemblage of fossils dated to roughly 309 million years ago is prompting scientists to rethink a...

A newly discovered Mexican fossil axolotl offers the country’s oldest record of the genus and uncovers surprising clues about its early evolution. Paleontologists have uncovered a fossil salamander from central Mexico that pushes back the record of the...

Recent research suggests that complex cells were already surprisingly sophisticated long before they gained mitochondria, reshaping how scientists think about the origin of animals, plants, and fungi. If you imagine the first complex cells on Earth,...

An affordable, widely available test can impact today's biggest healthcare challenge. An affordable, widely available test can impact today’s biggest healthcare challenge. Sepsis, the inflammatory response to infection, is quickly becoming one of the...

A new model published in Nature Geoscience predicts when Earth’s oxygen-rich atmosphere will eventually collapse, marking a turning point for life. Our planet’s hospitable, oxygen-rich atmosphere is a fleeting luxury in the grander timeline of the...

Study finds deep‑space stress mimics accelerated aging, hinting at new therapies for astronauts and Earth patients. Living beyond Earth’s protective shield may reveal crucial insights into how the human body ages. A recent paper in GeroScience shows...

A 415‑million‑year‑old fossil claw reveals a giant predator that reshapes our view of life’s earliest move onto land. A 16‑centimetre claw discovered in the United Kingdom has finally settled a debate that has persisted for more than a hundred years:...

Mysterious stone markings reveal a hidden chapter of Earth’s past, offering unexpected fossil evidence that reshapes our understanding of ancient life. Researchers have identified enigmatic depressions and linear marks in ancient Italian sedimentary...

Fossil study of Spriggina floundersi uncovers 550‑million‑year‑old movement patterns, hinting that modern animal traits have far older evolutionary roots. A team of paleontologists has identified a directional bias in the body curvature of an ancient...

Scientists have discovered a 99-million-year-old insect in amber with specialized, extendable mouthparts evolved to reach hidden plant fluids in tree bark. A newly identified species of ancient planthopper has shed light on a remarkable, forgotten...

Southern France rocks reveal rare fossils that preserve normally lost soft tissues, offering scientists a detailed glimpse into ancient life. Scientists have catalogued close to four hundred fossils that date back roughly 470 million years, many of...

The WHO estimates that worldwide, 453,000 children younger than age 5 died from rotavirus infection in 2008. But countries that have introduced the vaccine have reported sharp declines in rotavirus hospitalizations and deaths. Deadly Diseases Humans...

Despite living for centuries in near darkness, the Greenland shark retains a fully functional visual system, revealing how evolution preserves vision even in the cold, dim depths of the Arctic deep sea. In the cold, silent depths of the Arctic Ocean,...
