Cryo-EM Reveals CDCA7's Hemimethylation Sensing in Nucleosome Core Particles

DNA methylation, a process by which methyl groups are added to DNA molecules, is essential for the maintenance of DNA and the overall health of an organism. Disruptions in the standard DNA methylation patterns can lead to immunodeficiency and diseases such as cancer.

New Imaging Technique Offers Clearer View of Brain Function

Researchers have developed a new two-photon fluorescence microscope that captures high-speed images of neural activity at cellular resolution. By imaging much faster and with less harm to brain tissue than traditional two-photon microscopy, the new approach could provide a clearer view of how neurons communicate in real time, leading to new insights into brain function and neurological diseases.

Spontaneous Brain Activity Drives Early Neural Circuit Formation

In humans, the process of learning is driven by different groups of cells in the brain firing together. For instance, when the neurons associated with the process of recognizing a dog begin to fire in a coordinated manner in response to the cells that encode the features of a dog -; four legs, fur, a tail, etc. -; a young child will eventually be able to identify dogs going forward. But brain wiring begins before humans are born, before they have experiences or senses like sight to guide this cellular circuitry. How does that happen?

New Microscope Peels Back Layers of Cellular Mystery

What does the inside of a cell really look like? In the past, standard microscopes were limited in how well they could answer this question. Now, researchers from the Universities of Göttingen and Oxford, in collaboration with the University Medical Center Göttingen (UMG), have succeeded in developing a microscope with resolutions better than five nanometers (five billionths of a meter). This is roughly equivalent to the width of a hair split into 10,000 strands. Their new method was published in Nature Photonics.

Geographic Origin Plays Key Role in Tuberculosis Infection, Harvard Study Finds

For some forms of tuberculosis, the chances that an exposed person will get infected depend on whether the individual and the bacteria share a hometown, according to a new study comparing how different strains move through mixed populations in cosmopolitan cities.

Cryo-EM Reveals Structural Differences in Fetal and Adult Muscle Receptors

The connections between the nervous system and muscles develop differently across the kingdom of life. It takes newborn humans roughly a year to develop the proper muscular systems that support the ability to walk, while cows can walk mere minutes after birth and run not long after.
