A team of biologists studying the tree of life has unveiled a new classification system for cell nuclei and discovered a method for transmuting one type of cell nucleus into another.

A new study exploits the characteristic epigenetic signatures of childhood tumors to detect, classify and monitor the disease.

A massive genome-wide association study (GWAS) of genetic and health records of 1.2 million people from four separate data banks has identified 178 gene variants linked to major depression.

To probe the traits of post-radiotherapy cancer genomics, a research team analyzed gliomas, a type of brain cancer, both when they first arose and after they recurred. The researchers also reviewed data from ~ 3,700 other post-treatment metastatic tumors.

Normal cells usually have multiple solutions for fixing problems, for example, they have several repair mechanisms if their DNA becomes damaged. But cancer cells may "put all their eggs in one basket", leaving them vulnerable.

A research collaboration specializes in high-resolution fluorescence microscopy and computational modeling to visualize and describe such stuff-of-life processes in exquisite detail, in real time, at the level of single genes. Now, scientists have, for the first time, observed early RNA transcription dynamics by recording where, when and how RNA polymerase enzymes kick off transcription by binding to a DNA sequence.

About 12,000 bacteria and viruses collected in sampling of public transit systems and hospitals around the world from 2015 to 2017 had never before been identified, according to a recent study which is part of a global effort to track microbes.

Researchers have provided a comprehensive portrait of the Californian SARS-CoV-2 variant, including its interaction with the immune system and its potential to spread.

Research has shed light on the complex dynamics involved in how organisms sense that an infection is taking place.

Researchers have studied the evolution of Tasmanian devils in response to a unique transmissible cancer, devil facial tumor disease.
