The methodology involves modifying histones and displaying them on the cell surface for analysis.

Symptoms documented in cases of long COVID are wide ranging and variable.

Scientists are banking various samples from recipients of donated uteruses to learn all they can about the biology of the organ, and about transplantation more generally.

Work in rodents shows that the bacteria living in a mother’s gut can produce immunomodulatory metabolites and influence the production of maternal antibodies—both of which can affect her offspring’s development.

Researchers propose a mechanism by which a protein produced in the placenta may trigger blood vessel growth and enlarge fat cells.

Researchers are using experiments and observational studies to look for host genetic variation that could be partly determined by the gut microbiota.

Stable, long-term cell lines will enable scientists to study everything from coral bleaching to biomineralization, knowledge that may help protect corals from ongoing climate change.

More than a dozen vaccines for tuberculosis are currently being tested in clinical trials. Some use whole bacteria as BCG does, while others deliver protein subunits or genetic material carried by viral vectors.  

So-called mossy fiber synapses in the hippocampus can meter the amount of neurotransmitter they receive by sending glutamate against the usual direction of synaptic flow.

Research in mice and humans points to oxidative stress and inflammation as likely drivers of noise-induced health effects such as hypertension and heart disease.

Unlike other cellular appendages, bacterial nanotubes are made solely of lipids and can connect the cytoplasm of different microbial species.

A study finds that slower-growing species are better able to adjust their growth to fit their hyphae through narrow passages.

Differences in how researchers prepare and image samples can lead to discrepancies in their results.

Researchers use magnetic nanoparticles and liquid-handling robots in an effort to detect COVID-19 outbreaks early.

The offspring of crosses between related species can sometimes fill a new environmental niche, and such hybridizations may even lead to speciation.

Historical and modern experiments have hinted that unicelluar organisms can learn from their experiences, but the idea still has its critics.

It’s now thought that in many cases, cancer cells disseminate from the primary tumor site early on and lay dormant for long periods rather than only venturing out from primary tumors at an advanced stage.

Researchers are uncovering how circular bits of DNA found in some cancer cells can help tumors evolve and kill.

Synapses in the mouse neocortex can release multiple packages of neurotransmitters, suggesting that connection strength is more flexible than previously thought.
