Protein may improve liver regeneration
Researchers at UC Davis have illuminated an important distinction between mice and humans: how human livers heal.

How DNA alarm-system works
Research from Lomonosov Moscow State University clarifies how DNA damage signalling works.

A long-standing mystery in membrane traffic solved
Researchers have discovered that NSF unravels a single SNARE complex using one round ATP turnover by tearing the complex with a single burst, contradicting a previous theory that it unwinds in a progressive manner.

Scientists uncover key cellular mechanism involved in neurodegeneration and herpes
A team of scientists have uncovered vital new information about the transport mechanism that works within cells, distributing elements to different areas and thus supporting a range of different cellular processes.

Stem cells make similar decisions to humans
Scientists at the University of Copenhagen have captured thousands of progenitor cells of the pancreas on video as they made decisions to divide and expand the organ or to specialize into the endocrine cells that regulate our blood sugar levels.

Chemical tag marks future microRNAs for processing, study shows
Just as two DNA strands naturally arrange themselves into a helix, RNA can form hairpin-like loops. But unlike DNA, which has a single job, RNA can play many parts—including acting as a precursor for small molecules that block the activity of genes.

Cytomegalovirus hijacks human enzyme for replication
More than 60 percent of the world’s population is infected with a type of herpes virus called human cytomegalovirus. The virus replicates by commandeering the host cell’s metabolism but the details of this manoeuvre are unclear.

Researchers’ breakthrough identification of important protein
Researchers from the University of Copenhagen are the first in the world to develop a secure way of measuring the important protein apo-M. This could prove relevant for research into diseases such as diabetes, arteriosclerosis and sclerosis.

Scientists pinpoint molecule that switches on stem cell genes
Experiments placed Sox9 at the crux of a shift in gene expression associated with hair follicle stem cell identity.

Structure of genetic messenger molecules reveals key role in diseases
A new study by UCL researchers has shown how the 3-D structures of mRNAs determine their stability and efficiency inside cells. It could help to explain how seemingly minor mutations that alter mRNA structure might cause things to go wrong in neurodegener

Neuroscientists identify cell type in the brain that controls body clock circadian rhythms
UT Southwestern Medical Center neuroscientists have identified key cells within the brain that are critical for determining circadian rhythms, the 24-hour processes that control sleep and other important body functions such as hormone production.

Scientists find DNA is packaged like a yoyo
To pack two metres of DNA into a microscopic cell, the string of genetic information must be wound extremely carefully into chromosomes. Surprisingly the DNA’s sequence causes it to be coiled and uncoiled much like a yoyo, scientists have reported.

Organisms can keep gene expression in check
Researchers have learned how living beings can keep gene expression in check – which might partly explain the uncontrolled gene expression found in many cancers.

Scientists find hidden meaning and ‘speed limits’ within genetic code
Case Western Reserve scientists have discovered that speed matters when it comes to how messenger RNA (mRNA) deciphers critical information within the genetic code.

DNA-directed RNA transcription may have profound adaptability
The central dogma of molecular biology describes the flow of genetic information. It was first described by Francis Crick in 1956 as one-way traffic: as: “DNA makes RNA and RNA makes protein.”
