skew data by physically stressing the cells. The human genome is a marvel of biological engineering, packing two meters of DNA into a nucleus only 10 micrometers wide. Because this tight organization is critical for gene expression, any disruption can...

the creation of the inaugural synthetic cell assembled solely from inert chemical parts that can enlarge, duplicate its DNA, and undergo division. Dubbed SpudCell, the construct marks a notable advance for synthetic biology, even though it does not meet...

fragments of the Shroud of Turin, aiming to map the microscopic life that has colonized the linen over centuries of exposure. DNA Profiling Uncovers a Mosaic of Microbial Residents By extracting minute fiber portions and amplifying their genetic...

scientists to re‑evaluate archived specimens. As detailed in a recent Zootaxa article, the combination of fresh fieldwork and DNA sequencing revealed a species that had been hiding in plain sight. Decades‑Long Collection Yields a New Species The...

A long-running forgery trial and new DNA research have reignited the intense scientific and historical debate surrounding the potential siblings of Jesus. For centuries, the potential existence of biological siblings of Jesus has fueled theological...

unveiled SpudCell, a synthetic construct capable of feeding, competing for resources, growing, dividing, and replicating its DNA—effectively completing a full cellular life cycle. While it lacks the ability to synthesize its own protein-building...

is one of science’s most enduring mysteries. A dominant theory, the RNA World hypothesis, posits that RNA preceded both DNA and proteins, functioning simultaneously as a genetic blueprint and a biological catalyst. While the discovery in the 1980s that...

bacteria together with psychrophilic yeasts that appear to have colonised him during his prolonged stay in the ice. Beyond DNA: Mapping the Mummy’s Microbial Landscape Distinguishing the original microbes from later intruders required a multi‑sample...

including the breakdown of carbohydrates, proteins, and fats to produce energy. They also play a role in the synthesis of DNA and red blood cells. Minerals, on the other hand, are inorganic elements that are essential for the proper functioning of...

tests provide 99.9% accuracy. Next-Generation Sequencing (NGS): This test sequences large amounts of deoxyribonucleic acid (DNA) rapidly, for determining the order of the DNA building blocks in the genetic code of the person. NGS is capable of looking...

is a precursor to NAD+ (Nicotinamide Adenine Dinucleotide), a vital coenzyme that plays a critical role in energy production, DNA repair, and overall cellular health. NAD+ is involved in a range of essential processes in the body, including regulating...

for growth, repair, and enzymatic activities. 2. Nucleoid Region The nucleoid is an unbounded region containing the circular DNA of prokaryotes. It serves as the control center for genetic activities, including replication and transcription. 3. Cell...

biological advantages can mean the difference between life and death. Over many generations, those advantages leave marks in DNA. Scientists can still see them today. Sudan at the Crossroads of Continents Sudan sits at a natural meeting point. Africa...

not be 100 percent sure which species they have found because the differences are so small. Some scientists have tried using DNA testing to solve this problem. They take a small sample of hair or a tiny piece of skin from the animal to look at its...

to see fine details of shells and teeth. These details are critical for distinguishing one species from another. Adding DNA Evidence Whenever possible, the team also analyzed DNA. They focused on a mitochondrial gene commonly used to identify animal...

DNA from seven individuals who lived 6,000 years ago reveals a mysterious ancient lineage that seemingly vanished from the historical record. Archaeologists working on the high-altitude plains of Colombia have uncovered a genetic mystery that...

at Colossal, noted that these eggs provide unique insights into the biology of the species, potentially yielding ancient DNA. The partnership aims to ensure that any research findings remain intrinsically linked to New Zealand. “Fewer than 40 whole moa...

recently detailed in the journal Behavior Genetics, highlight that while people do not necessarily choose partners based on DNA, the resulting unions create lasting genetic patterns. The Genetic Signatures of Romantic Choice Assortative mating is not...

near‑impervious reputation. The first is a protein known as Dsup (damage suppressor), which acts like a protective coat for DNA against ionising radiation. The second is a reversible state called cryptobiosis, during which the animal evacuates water,...

glaciers usually erode older deposits—a factor that makes this site uniquely valuable. Combining Morphology and Ancient DNA to Pinpoint Species To determine the identity of the fragmented remains, researchers applied classic bone morphology alongside...
