New understanding of RNA movements can be used to treat cancer

Research from Karolinska Institutet published today in Nature shows that an RNA molecule involved in preventing tumour formation can change its structure and thereby control protein production in the cell. The finding can ...

Uncovering the role of membrane sugars in flu infection

The flu virus relies on using human cells to reproduce and spread. But before it even gets to the cell surface, the virus must navigate the tall, dense forest of sugar-coated proteins on the cell surface known as the glycocalyx. ...

MetaviralSPAdes—New assembler for virus genomes

When a new virus emerges, biologists rush to reconstruct its genome—a prerequisite for future diagnostic and vaccine development. The challenge with viral sequencing during an outbreak is that a sample from a patient, like ...

The chemical messenger that controls flower power

The dazzling floral displays of early spring are starting to draw to a close. But wily gardeners know that they can keep plants in flower for longer by removing fruit and seeds as soon as they form.

Taming CRISPR's collateral damage

CRISPR-Cas9 can alter genes at pre-defined sites in specific ways, but it does not always act as planned. An LMU team has now developed a simple method to detect unintended "on-target" events, and shown that they often occur ...

Urge to merge: Understanding how cells fuse

Scientists have known for a decade that cells that fuse with others to perform their essential functions—such as muscle cells that join together to make fibers—form long projections that invade the territory of their ...

Chromosomal speciation in wild house mice

Alterations to chromosomes are considered important in speciation (the process by which new species are formed). This is because several chromosomal rearrangements can make the genome of a few individuals in a population ...

Editing plant chromosomes using molecular scissors

The CRISPR/Cas molecular scissors work like a fine surgical instrument and can be used to modify genetic information in plants. The research teams of Professor Holger Puchta of Karlsruhe Institute of Technology (KIT) and ...

Directed protein evolution with CRISPR-Cas9

"Directed evolution" is the process by which scientists produce tailor-made proteins for cell biology, physiology and biomedicine in the laboratory. Based on this method, Max Planck researchers from Martinsried have now developed ...

Scientists discover how cells respond to fasting

As modern life-styles and high calorie diets drive the UK's obesity levels up, researchers from the University of Warwick have found how cells respond to fasting and activate the process called autophagy, which means a healthier ...

The first 3-D map of the heart's neurons

The normal functioning of our hearts is maintained by our body's control center—the brain—via an intricate network of nerves. When this communication is disrupted, it results in heart disease, including heart attacks, ...
