In a new study, researchers at Uppsala University have found evidence of a new principle for how epigenetic changes can occur. The principle is based on an enzyme, tryptase, that has epigenetic effects that cause cells to proliferate in...

In a new study, researchers at Uppsala University have found evidence of that climate change upends selection of face characteristics in the collared flycatcher. During the study the annual fitness selection on forehead patch size switched from...

Scientists have made a breakthrough in understanding how different compartments (or organelles) of human cells interact.

The images above show key structural proteins (actin and tubulin) as cells age. The top raw shows still dividing, and, the bottom raw shows senescent (cells that no longer divide) cells. Their comparison highlights the difference in shape of...
In a time series of super-resolution microscopic images of the epigenetic marks in the nuclei of stem cells, stem cells differentiate into distinct cell types—bone and fat. Using texture analysis, researchers can discern the conversion of stem cells as...
Cryo-electron tomography shows how the bacterial cell is reorganized to resemble a more complicated plant or animal cell with a red nucleus-like compartment and ribosomes, the smaller light blue structures. The reproducing viruses appear with dark blue heads and...
Photo of an Egyptian fruit bat. Sarel et al. report on a new functional class of hippocampal neurons in bats, which encode the direction and distance to spatial goals – suggesting a novel neural mechanism for vector-based goal-directed navigation....
Using X-rays to visualize DNA (dark gray) and fluorescence to monitor the histone proteins (yellow and cyan), Cornell researchers led by professor and director of applied and engineering physics Lois Pollack found that the release of histone proteins is...
A visual description of the CRISPR/Cas9 research explored by UNT researchers using TACC supercomputers. Simulations found that Cas9 produces staggered, "sticky" ends, which may make them easier to manipulate for future use.Credit: Jin Liu and Zhicheng Zuo, UNT

Neuroscientists at MIT have adapted their MRI scanner to make it easier to scan infants’ brains as the babies watch movies featuring different types of visual input. With the new technique, the team found that in some ways, the...
