New insights into DNA phase separation
A recent study has presented the notion of 'DNA Phase Separation', which suggests that the DNA within the nucleus may trigger phase separation, like oil in water.

CRISPR screen identifies gene that helps cells resist West Nile, Zika viruses
Researchers now report the first use of CRISPR genome-wide screening to identify a gene that helps cells resist flavivirus infection.

Newly discovered enzyme is 'firing pin' for plant immunity
Just like humans, plants have an immune system that helps them fight off infections. Researchers have now identified a key step in how plant cells respond to pathogens -- a family of kinase enzymes that activate the enzymes that make reactive oxygen.

Mapping vast unknown territory of long non-coding RNA
Scientists have developed a powerful method for exploring the properties of mysterious molecules called long non-coding RNAs (lncRNAs), some of which have big roles in cancer and other serious conditions.

Gene therapy via skin protects mice from lethal cocaine doses
A new study shows that skin stem cells, modified via CRISPR and transplanted back to donor mice, can protect addicted mice from cocaine-seeking and overdose.

How cells handle a sticky, toxic, but absolutely essential molecule
A team of researchers has solved a long-standing puzzle by identifying the protein that 'chaperones' free heme in cells.

Viruses under the microscope
Human herpesviruses such as HHV-6 can remain dormant in cells for many years without being noticed. When reactivated, they can cause serious clinical conditions. Researchers have now found a way of differentiating between active and inactive viruses.

We have more than enough calories, but what about other nutrients?
A new study is the first to quantitatively map the flow of energy, protein, fat, essential amino acids and micronutrients from 'field-to-fork' at a global level and identify hotspots where nutrients are lost. The study shows that while we produce far more nutrients than is required for the global population, inefficiencies in the supply chain leave many people nutrient deficient.

A very special protein synthesis machinery
Sleeping sickness-causing parasites contain an unusual protein synthesis machinery. A team of researchers has resolved its very special structure for the first time.

High-resolution genomic map gives scientists unprecedented view of brain development
Researchers have created a massive database of the changes in gene activity of individual cells in the cerebellum during embryonic development and immediately after birth. The analysis of thousands of brain cells isolated from mice offers researchers a high-resolution map that enables scientists to view the detailed genomic changes cells undergo as the cerebellum wires its neural circuitry.
