1+ day, 13+ hour ago   (439+ words) AMES, Iowa—A tiny, antenna-like structure found on many animal cells may help explain how turtle embryos sense the warmth that determines whether they develop as male or female....

1+ day, 14+ hour ago   (501+ words) Researchers have developed a computer model of the human cortex that connects molecular-scale chemistry with brain-wide patterns of activity, offering new evidence that differences in receptor density can influence how information travels through the brain. The study, published in the…...

1+ day, 22+ hour ago   (76+ words) Aging may leave a genetic record in nearly every tissue of the human body, written not in the DNA inherited at conception but in mutations acquired during life. A review by E. Pan, A. Maslov and J. Vijg, published in Experimental & Molecular Medicine,…...

2+ day, 10+ hour ago   (517+ words) Scientists have reconstructed the most complete diploid human genome yet produced, creating a high-resolution sequence that contains both copies of every chromosome inherited from an individual’s parents....

2+ day, 21+ hour ago   (558+ words) Women may hold one of nature’s most important clues to the biology of aging, according to a new perspective published in Cell. The paper introduces the Reproductive Resilience Hypothesis, an evolutionary framework proposing that reproduction and longevity are not always…...

2+ day, 21+ hour ago   (509+ words) Scientists have produced the first complete, end-to-end genome sequence of the common marmoset, creating a high-resolution genetic reference for one of the world’s most important emerging primate models of human disease....

3+ day, 2+ hour ago   (608+ words) The insula, a folded region tucked deep within the lateral sulcus of the cerebral cortex, is emerging as one of neuroscience’s most important—and most complicated—research targets. Once treated largely as a sensory relay, the insular cortex is now…...

3+ day, 10+ hour ago   (477+ words) Hydrogels are among the most promising materials in modern biomedicine. They are soft, water-rich networks that can resemble the physical environment of living tissue, making them useful for drug delivery, wound treatment, tissue engineering and regenerative medicine....

3+ day, 16+ hour ago   (448+ words) A new study has identified an important spatial principle governing how mitochondria support developing neurons: the machinery that controls mitochondrial calcium is not distributed evenly throughout the cell. Instead, calcium regulators appear to be positioned asymmetrically across neuronal compartments, allowing…...
