Huntington’s disease offers a rare clean test case for brain research
Neuroscience rarely enjoys clean experiments. Most brain disorders are mosaics of risk genes, aging, lifestyle and chance that leave their origins obscured. Huntington’s disease (HD) is different. It begins with a single genetic expansion—a repeated st…

Preventing ‘spermageddon’—discovery of an immune-like mechanism that protects fertility
New insights into a sophisticated process that protects sperm cells has revealed a mechanism, similar to an immune system, thwarts genetic chaos during the earliest stages of their development.

Scientists build virtual tissue tools to map how cells talk in disease
Scientists at Duke-NUS Medical School have developed two powerful computational tools that could transform how researchers study the «conversations» between cells inside the body. The tools, called sCCIgen and QuadST, help scientists understand both wh…

When ribosomes collide, cells launch emergency stress defenses
Ribosomes, the protein factories of the cell, are essential for all living organisms. They bind to mRNA and move along the messenger molecule, reading the genetic code as they go. Using this information, they link amino acids to make proteins.

Population-specific genetic risk scores advance precision medicine for Han Chinese populations
Researchers at Academia Sinica have developed the first population-specific polygenic risk score (PRS) models for people of Han Chinese ancestry, achieving unprecedented accuracy in predicting risks for common diseases such as diabetes, heart disease, …
