Researchers “counted” Japanese jack mackerel (Trachurus japonicus) in Maizuru Bay, Japan, through quantitative measurements of environmental DNA concentration. Credit: Reiji Masuda, Kyoto University River water,…
Scientists have shown that a large group of viruses, including the influenza viruses and other serious pathogens, steal genetic signals from their hosts to expand…
By folding DNA into a virus-like structure, MIT researchers have designed HIV-like particles that provoke a strong immune response from human immune cells grown in…
The pistils in mutant strains contain a higher number of stigmas — the part of the pistil that collects pollen — than in wildtype strains.…
Gene editing Cas9 protein. Applied computational biology discoveries vastly expand the range of CRISPR’s access to DNA sequences. In nature, bacteria use CRISPR as an…
In this figure, neurons in the bottom row, which are missing the HDAC1 gene, show higher levels of DNA damage (green) than normal neurons. Credit:…
The man in grave 54 from the Ajvide Pitted Ware burial ground on Gotland is buried flat on his back, which is typical of Pitted…
Scientists have long debated which genetic information carrier — DNA or RNA — started life on Earth, but a new study suggests life could have…

Maximizing the protection of life on Earth requires knowledge of the global patterns of biodiversity at multiple dimensions, from genetic diversity within species, to species…
DNA may not be life’s instruction book, but just a jumbled list of ingredients. University of Maryland researcher develops potentially revolutionary framework for heredity and…
Salmonella are gram-negative, rod-shaped, facultative anerobic bacteria. Zhang et al developed sensitive and specific assays to detect different serotypes of Salmonella, paving the way for…

An international research team has conducted the first in-depth, wide-scale study of the genomic history of ancient civilizations in the central Andes mountains and coast…
Using machine learning, a team of Western computer scientists and biologists have identified an underlying genomic signature for 29 different COVID-19 DNA sequences. This new…
Millions of people have been tested for the novel coronavirus, most using a kit that relies on the polymerase chain reaction (PCR). This sensitive method…
Researchers at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan have identified a new mechanism that helps animals to develop with precise and…
‘Brown tide virus’ is a member of a class called the giant viruses. Researchers have discovered genes for key cellular metabolic cycles in many giant…
The virus that causes COVID-19, called SARS-CoV-2, shown here in an electron microscope image, can trigger severe cases of infection in some younger patients. Studying…
