replication

When Caulobacter crescentus finds itself in a nutrient-poor environment, it clusters an enzyme necessary for cell division thanks to a physical phenomenon known as phase separation so it can make better use of dwindling fuel.

When the bacterium Caulobacter crescentus runs low on fuel, it can still replicate by clustering its remaining ATP around the cell division enzyme DivJ.

Study finds that, contrary to what other research has found, a popular meditation course does not appear to alter brain structure.

Researchers involved in an eight-year project to reproduce the findings of more than 50 high-impact papers struggled to get enough information to even carry out most of the experiments.

Biological robots made from frog cells can replicate by smooshing loose cells into new robots—a reproduction method not seen in any other organism.

Finding and reporting an irregularity in a published study can lead people down an unexpected path.

Researchers who spoke with Spectrum say that while brain imaging tools have their limitations, they still hold promise in helping to unlock the brain’s secrets. 

Several labs have reported the formation of bacterial nanotubes under different, often contrasting conditions. What are these structures and why are they so hard to reproduce?

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

While studying a degenerative eye disease, researchers find the first evidence that cells produce endogenous DNA in the cytoplasm. Drugs that block this activity are linked with reduced risk of atrophic age-related macular degeneration.

Working with a virus that infects bacteria, the Stanford University biochemist and developmental biologist helped to develop a way to stitch DNA together, a discovery that gave rise to genetic engineering.

At Bessy II, a synchrotron radiation facility in Berlin, scientists use X-rays to study the structure of SARS-CoV-2.

Cell lines from individuals with macrocephalic autism spectrum disorder have an increased number of double-strand breaks in the DNA of long neural genes.

The new experiments use standardized methods and video recordings, but some researchers stand by earlier evidence that ocean pH influences coral reef fish’s response to predator cues.

A mixture of chemicals induces reactions reminiscent of life on pyrite.

The original experiment found brain activity as measured by fMRI was tied to particular genetic variants.

The new work calls into question the idea that neurons can be genetically engineered to fire in response to magnetic fields, a setback for the budding technique.

These failures were not due to differences among sample populations.

Researchers from 17 labs report low efficacy rates for the popular technique.
