It’s not clear why the patients with Leber hereditary optic neuropathy, a mitochondrial disorder that causes blindness, also experienced the modest benefits in their untreated eye.
Researchers repaired what is otherwise irreversible damage in the animals’ ocular neurons, by activating transcription factors ordinarily used to generate induced pluripotent stem cells.
The so-called 614G mutation in the viral spike protein does not appear to cause more severe cases of COVID-19, but multiple studies indicate that it could be more contagious.
A study explains how Zika was present among mosquitoes in Africa for decades without causing the harm to human health seen outside the continent in recent years.
Whole genome sequencing of the virus infecting the farm animals showed that it spread from the workers to the mink and back, indicating that an animal could serve as a viral reservoir.
A “larger than life personality,” Amon devoted her career to studying the cell cycle and aneuploidy. Her research has shaped the field of cancer biology.
An analysis of the genomes of people from 50 ethnolinguistic groups in Africa spots 62 genes under positive selection and 3 million more genetic variants than previously documented.
While sick with COVID-19, President Trump is taking an antacid. Doctors have been exploring whether these medicines can treat SARS-CoV-2 infections, and the results are mixed.
A decade-long effort to probe gene regulation reveals differences between males and females, points to essential regulatory elements, and offers insight into past work on telomeres.
Officials had initially linked 97 cases to a single conference held by Biogen in February in Boston, but a new study tracking viral genomes suggests the number may be as high as 20,000.
There have been no reports of health or environmental harm in other locations where genetically modified mosquitoes have been introduced over the last decade.
In a genome-wide association study, variants in both the ABO blood group locus and a cluster of genes on human chromosome 3 are more common among COVID-19 patients with respiratory failure than in the general population.
