Shaking up cell biology: Researchers focus in on decades-old mitochondrial mystery
Elvis did it, Michael Jackson did it, and so do the mitochondria in our cells. They shake. While Elvis and Michael shook for decades before loud and appreciative audiences, mitochondrial oscillations have ...
Breakthrough study discovers six changing faces of 'global killer' bacteria
Every ten seconds a human being dies from Streptococcus pneumoniae infection, also known as pneumococcus, making it a leading global killer.
RCas9: A programmable RNA editing tool
A powerful scientific tool for editing the DNA instructions in a genome can now also be applied to RNA, the molecule that translates DNA's genetic instructions into the production of proteins. A team of researchers ...
Scientists identify "naïve-like" human stem cell
Scientists from our university and Berlin have identified a type of human stem cell that appears to be "naïve-like" – able to develop into any type of cell. The discovery of this cell type could potentially ...
Designer viruses could be the new antibiotics
Bacterial infections remain a major threat to human and animal health. Worse still, the catalogue of useful antibiotics is shrinking as pathogens build up resistance to these drugs. There are few promising ...
Scientists identify key factor that maintains stem cell identity
A protein implicated in several cancers appears to play a pivotal role in keeping stem cells in an immature "pluripotent" state, according to a new study by NYU Langone Medical Center scientists. The study ...
Primitive microbes stole bacterial genes on a surprising scale
A University of Otago researcher is part of an international team that has discovered that horizontal gene transfer (HGT) played a surprisingly large role in the evolution of primitive microbes known as archaea.
Study reveals messenger molecules in cell walls can double as hormones
Researchers have discovered that some common messenger molecules in human cells double as hormones when bound to a protein that interacts with DNA. The finding could bring to light a class of previously unknown ...
Genesis of the enzyme that divides the DNA double helix during cell replication
The proteins that drive DNA replication—the force behind cellular growth and reproduction—are some of the most complex machines on Earth. The multistep replication process involves hundreds of atomic-scale ...
How a molecular Superman protects the genome from damage
How many times have we seen Superman swoop down from the heavens and rescue a would-be victim from a rapidly oncoming train?
New studies bring scientists closer to combating dangerous unstable proteins
Scientists at The Scripps Research Institute (TSRI) have discovered a way to decrease deadly protein deposits in the heart, kidney and other organs associated with a group of human diseases called the systemic amyloid diseases.
Thanks, fruit flies, for that pleasing beer scent
The familiar smell of beer is due in part to aroma compounds produced by common brewer's yeast. Now, researchers reporting in the Cell Press journal Cell Reports on October 9th have discovered why the ye ...
Researchers find animals killed by anthrax leave behind enticing grasses for herbivores, allowing disease to spread
First pictures of BRCA2 protein show how it works to repair DNA
Scientists have taken pictures of the BRCA2 protein for the first time, showing how it works to repair damaged DNA.
