Bettas were likely the first fish welcomed into human homes. Now, scientists are welcoming them into the lab to learn how genes dictate their appearance and behavior.

Not only is the humble fluid a boon for keeping humans cool, it also contains a wealth of biological information.

A comparison of interferon-related genes across 20 primate genomes reveals differences in the speed at which they evolve and new targets for antiviral discovery efforts.

A massive, well-preserved skull discovered in China in the 1930s belongs to a new species called Homo longi, researchers report, but experts remain skeptical about the evidence.

Some of the blood specimens collected in the United States for the NIH’s All of Us research program starting on January 2, 2020, have antibodies against SARS-CoV-2.

The largest study to date of the animals’ genetics provides robust evidence that they are adapting to survive a highly lethal, contagious cancer scientists feared would cause their extinction.

Researchers find that surges in COVID-19 case numbers are associated with deletions in the SARS-CoV-2 genome in an antigenic site of the spike protein. Some of these mutations are present in vaccine breakthrough infections or reinfections.

In a preprint, researchers fill in some of the holes left in the first draft of the human genetic code, published at the turn of the century.

New analyses find that divergent transcription, in which one promoter directs the expression of two adjacent genes oriented in opposite directions, is conserved across all domains of life.

In the largest effort to date to standardize performance metrics of the cancer diagnostic across products, researchers say the products can likely detect advanced tumors reliably, but early-stage malignancies would remain a challenge.

Researchers find that SARS-CoV-2 variants can evade primer-probe sets and recommend that diagnostic assays include multiple targets for reliability.

Four dozen children with severe combined immunodeficiency (SCID) who received a corrective gene carried by a virus have working immune systems two to three years later, according to three independent clinical trials.

The transcription of DNA drives the remarkably tidy organization of chromosomes in the dinoflagellate Symbiodinium microadriaticum.

Avoiding inbreeding appears to be the exception rather than the norm for animals, according to a new meta-analysis of experimental studies.

Data from three studies indicate that fully vaccinated patients are able to stave off severe disease from the B.1.1.7, B.1.351, and P.1 variants.

The genome sequences of 51 giraffes from all over Africa contribute to the latest attempt in an ongoing pursuit to pin down a species number.

After years of push back, the first batch of Oxitec’s engineered mosquitoes, designed to reduce population numbers, have been released in the Keys.

While some experts speculate the variant could be partially responsible for India’s current surge in SARS-CoV-2 infections, information about the effects of its mutations is only beginning to emerge.

Whether the galls that aphids make on witch hazel leaves are red or green is associated with a gene expressed in the insects’ salivary glands.
