New insight as to how cells maintain their identity

In the body's cells, some proteins are of vital importance as to which genes are active or turned off. Now, researchers from the University of Copenhagen and the Memorial Sloan Kettering Cancer Center have discovered which ...

Researchers show how railroad worms produce red light

A research group comprising Brazilian and Japanese scientists has discovered how luciferase produced by the railroad worm Phrixothrix hirtus emits red light. Luciferase is an enzyme that catalyzes the oxidation of luciferin ...

How to construct a protein factory

Cells consist of a multitude of molecular structures, some of them exhibiting a staggering complexity. Ribosomes, the protein factories of the cell, belong to the biggest and most sophisticated complexes and are made up of ...

Quality control in cells

A protective protein that can detect newly-made incomplete and hence potentially toxic protein chains in higher cells is found to have a relative in bacteria. There, the protein also plays a central role in quality control ...

New cells identified that repair tissue

Researchers at Oxford University have discovered that a newly discovered group of cells can help repair tissues in the body.

Researchers find way to study proteins moving (relatively) slowly

Proteins are the workhorses of our bodies. They keep our organs functioning. They regulate our cells. They are the targets for medications that treat a number of diseases, including cancers and neurological diseases. Proteins ...

Pros and cons of genetic scissors

Crispr technology has greatly facilitated gene editing. Associate Professor Thorsten Müller from Ruhr-Universität Bochum and Dr. Hassan Bukhari from Harvard Medical School discuss its pros and cons in a review article in ...

Victorian hog deer genetics revealed

Australian researchers looking for a genetic lifeline to endangered hog deer species endemic to Pakistan, northern India and mainland southeast Asia have found widespread hybridization of the species in Victoria.

Hair indicates whether wild animals were 'stressed'

While hair analysis has become routine in humans—for example for the detection of prolonged drug or medication abuse—it has been little used in animals to date. Scientists led by Alexandre Azevedo and Katarina Jewgenow ...

Extinction of Icelandic walrus coincides with Norse settlement

An international collaboration of scientists in Iceland, Denmark and the Netherlands has for the first time used ancient DNA analyses and C14-dating to demonstrate the past existence of a unique population of Icelandic walrus ...

Mother cells as organelle donors

Microbiologists at LMU and UoG have discovered a recycling process in the eukaryotic parasite Toxoplasma gondii that plays a vital role in the organism's unusual mode of reproduction.

Decoding messages in the body's microscopic metropolises

A study aimed at identifying and examining the small messenger proteins used by microbes living on and inside humans has revealed an astounding diversity of more than 4,000 families of molecules – many of which have never ...

A new methodology for sequencing viruses

NUS scientists have developed a more efficient method to sequence the complete genomes of infectious diseases carried by mosquitoes directly from patient samples.

Molecular biologists reveal new insights into tumor progression

University of Delaware molecular biologist Mona Batish and collaborators at Harvard Medical School and University of California, Los Angeles, have identified a new circular ribonucleic acid (RNA) that increases tumor activity ...
