For her doctoral dissertation, Yale’s Nathalie Alomar decided to study a small amphibian that appeared to have eluded the forces of evolution.
She found that there is more to its evolution than meets the eye.
In a new study, Alomar and a team of scientists report that the story of the common woodland salamander — long considered a classic example of “evolutionary stasis,” meaning that it has evolved into many species without changing its overall structure much at all — is more complicated than previously believed.
For the research, the team collected nearly 300 individual woodland salamanders — which are from the genus Plethodon, and ubiquitous in forests of the eastern United States — representing 30 distinct species. And while these animals looked quite similar, a subsequent laboratory analysis found that aspects of their physiology differed substantially.
A night without sleep produced increased markers of connections between brain cells, showing that sleep in humans may be important for restoring cellular balance in the brain, according to a study published June 23rd in the open access journal PLOS Biology by David Elmenhorst from the Forschungszentrum Jülich Institute of Neuroscience and Medicine in North Rhine-Westphalia, Germany, and colleagues.
The environment experienced by young zebrafish influences both the shape and electrical activity of the neurons in the eye, which impacts subsequent behaviour.
A new algorithm could drive breakthroughs in understanding cancer, Alzheimer’s disease, and other potentially fatal conditions.
Researchers from the University of Waterloo developed the machine learning algorithm, called RNovA, to detect changes in the proteins in human cells.
The genetic mechanisms regulating the metamorphosis of worker and queen bees from genetically identical insect larvae is poorly understood. A team of researchers recently identified 842 candidate enhancer sequences from 17,349 worker Apis mellifera transcription start sites that may help regulate the development of worker honeybees in this genus’ complex social caste system.
