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.

Health officials are searching for possible exposures to heavy metals, but no sources of contamination have been identified.

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 technology solves proteins’ 3-D shapes in minutes, when traditional methods may take years.

As COVID-19 therapies get emergency-use green lights, the Biden administration must organize a therapeutic review board to help identify what’s working and what’s not.

The newly minted Baylor College of Medicine faculty member is working to crack the mystery of triple negative breast cancer.

Take a break from the bench to puzzle and peruse.

As the world around us seems increasingly volatile, protecting and respecting the integrity of research and evidence becomes more important than ever.

A finding of distinct patterns of gene-regulating RNA snippets in the blood of ME/CFS patients in response to a stress test could pave the way for a diagnostic tool for the condition and help untangle its underlying mechanisms.

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.

Half a year after infection, people who had recovered from COVID-19 had robust antibodies, along with traces of the virus in their gut, which may drive long-lasting immunity.

Patients’ viral loads are highest within five days of their first symptoms, emphasizing the need to isolate early to prevent transmission.

The variant causes a buildup of BACE1 protein in axons in cultured neurons and mice. Researchers say it might be time to rethink failed trials that inhibit BACE1 to treat the neurodegenerative disease.

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.

An abundance of immunoglobulin antibodies, and a paucity of viral RNA, in breastmilk offer evidence that women can safely continue breastfeeding during the pandemic.

The results mark the second experimental COVID-19 vaccine to show high efficacy, but the study is not complete and the data have not been peer reviewed.

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 study finds that β-coronaviruses don’t use the normal secretory pathway, a possible explanation for some aspects of COVID-19 pathology.

Outcomes in COVID-19 patients may be better in those recently infected with endemic coronaviruses.
