Scientists extracted a near-complete HIV-1 genome from a lymph node that had been preserved in wax for more than 50 years. The sample stands as
When Sara Campbell first typed “exercise and microbiome” into PubMed in 2010 and hit enter, “the search literally said zero,” she tells The Scientist. Campbell
Two well-known gene mutations work in tandem to allow endometrial cells, the cells that line the uterus, to migrate outside of the organ, a phenomenon
Genetics hold far more sway over the mouse microbiome than transient environmental exposures, researchers reported July 26 in Applied and Environmental Microbiology. The results appear
Searching a sample of DNA for a particular sequence—be it a mutation, a researcher-inserted transgene, or evidence of an infecting organism—is a common practice in
Scientists report finding eight new genetic markers for the eating disorder anorexia nervosa in a study published in Nature Genetics today (July 15). By analyzing
Senators Dianne Feinstein (D-CA), Marco Rubio (R-FL), and Jack Reed (D-RI) introduced a resolution yesterday (July 15) calling for global collaboration in developing guidelines for
A study published today (June 3) in Nature Medicine confirms previous reports that a variant of the gene CCR5 that protects against infection by HIV
Patches of healthy tissue can contain groups of cells with genetic mutations, researchers reported June 6 in Science. In the study, they analyzed 29 different
In the murky darkness, blue and green blobs are dancing. Sometimes they keep decorous distances from each other, but other times they go cheek to
EDITOR’S CHOICE IN DEVELOPMENTAL BIOLOGY The paper K.M. Elias et al., “Primordial germ cells as a potential shared cell of origin for mucinous cystic neoplasms
RNA sequencing may help doctors diagnose hepatocellular carcinoma earlier, according to preliminary data presented Sunday (March 31) at the American Association for Cancer Research annual
Current genetic testing methods often fall short in diagnosing pediatric patients with developmental delay, intellectual disability, or congenital abnormalities. Sometimes, this is because certain genetic
An advisory panel to the World Health Organization has called for the creation of a global registry to monitor gene-editing research in humans, the organization
There should be a global moratorium on editing heritable DNA from humans, scientists and bioethicists from seven countries write today (March 13) in a Nature
A genetic variant present in 5 percent of the population is tied to substantially lower blood levels of the active ingredient in a hormonal contraceptive
Genetically engineered yeast produce the cannabinoids THC and CBD, researchers reported today (February 27) in Nature. Much like in their typical application of brewing beer,
HeLa cells have now been cultured for nearly 70 years in many labs across the world, and were long considered to be an infinite supply
The great white shark genome—like the animal itself—is giant, with 41 pairs of chromosomes compared to humans’ 23 pairs, researchers reported yesterday (January 18) in
The DNA of life on Earth naturally stores its information in just four key chemicals — guanine, cytosine, adenine and thymine, commonly referred to as
In late 2017, scientists first began attempting to edit the genes of adults to treat rare genetic disorders. Preliminary results from a clinical trial, shared
While scientists have evidence that the composition of the gut microbiome is connected to a variety of autoimmune diseases, understanding how bugs in the intestine
Neural tube defects such as spina bifida, where a part of the spinal cord fails to close, may be caused by the same genes that
Sequester and shutdown On March 1, automatic spending cuts—known as the sequester—went into effect in the federal budget. Government agencies across the board were affected.
Researchers have long puzzled over why many eukaryotic protein-coding genes are interspersed with segments of noncoding DNA that have no obvious biological function. These so-called
