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.

In the 20th century, animals such as mules and ligers that had parents of different species were considered biological flukes, but genetic sequencing is beginning to unravel the critical role of hybridization in evolution.
