Genomes of Two Millipede Species Shed Light on Their Evolution, Development and Physiology

Researchers have sequenced and analyzed complete genomes from two very different millipede species. The study provides important insights into ...

Bird Genes Are Multitaskers, Say Scientists

Scientists have found that although male and female birds have an almost identical set of genes, they function differently in each sex through a mechanism called alternative ...

Berry Good News: Newly Discovered Compound from Blueberries Could Treat Inflammatory Disorders

Inflammatory bowel disease (IBD), caused by chronic inflammation in the digestive tract linings, can be debilitating and life threatening. ...

CRISPR-Based Malaria Testing on-the-Fly

Looking at Evolution's Genealogy from Home

Evolution leaves its traces -- in particular -- in genomes. Researchers used '2-n-way' software to determine the relationships between species or individuals and compare any genome of and ...

Fungal Compound Inhibits Important Group of Proteins

Researchers have found that a compound inhibits a group of proteins called BMP receptors. This compound, called cercosporamide, was previously only known to inhibit a different group of proteins. ...

How Methanogens Are Able to Render Oxygen Molecules Harmless

We humans need oxygen to breath - for a lot of microbes it is a lethal poison. That is why microorganisms have developed ways to render oxygen molecules harmless. Microbiologists have now succeeded ...

Fine-Tuning Stem Cell Metabolism Prevents Hair Loss

An international research team has shown in mice that Rictor, a protein that helps to regulate the growth, energy, and oxygen consumption of cells, plays a key role in the cellular metabolism and ...

RAP Tag: A New Protein Purification Approach

Researchers describe a new approach for protein labeling and purification using plant ...

Lending Color to Dead Cells -- A Novel Natural Dye for Screening Cell Viability

Synthetic dyes are commonly used to assess the toxicity of chemical compounds in cell cultures. However, these dyes damage cells, rendering the cultures useless for long-term experiments. Recently, ...

A New Strategy of Cell Entry for Some Types of Parvoviruses

Researchers have uncovered a new parvovirus strategy for reaching the cell nucleus which is their site of replication. This new method of entry is a good example of host-driven ...

Likely Molecular Mechanisms of SARS-CoV-2 Pathogenesis Are Revealed by Network Biology

Researchers have built an interactome that includes the lung-epithelial cell host interactome integrated with a SARS-CoV-2 interactome. Applying network biology analysis tools to this ...

Unraveling the Genome in 3D-Space

Proper folding of extremely long chromosomal DNA molecules is crucial for the correct functioning of the cell. Scientists developed a groundbreaking method to map contact points between replicated ...

Structural Biology: Ribosomes and Russian Dolls

Maturation of the ribosome is a complex operation. Work now shows that the 90S precursor of the small 40S subunit undergoes a 'molting' process, during which it progressively discards its ...

New Mouse Model of Tau Propagation

Accumulation of assembled tau protein in the central nervous system is characteristic of Alzheimer's disease and several other neurodegenerative diseases, called tauopathies. Researchers have ...

'Cheater Mitochondria' May Profit from Cellular Stress Coping Mechanisms

Cheating mitochondria may take advantage of cellular mechanisms for coping with food scarcity in a simple worm to persist, even though this can reduce the worm's ...

Mechanism That Causes Cell Nuclei to Grow

Researchers discover a mechanism that causes cell nuclei to ...

Chemists Make Cellular Forces Visible at the Molecular Scale

Scientists have developed a new technique using tools made of luminescent DNA, lit up like fireflies, to visualize the mechanical forces of cells at the molecular ...

New Drug Candidate Found for Hand, Foot and Mouth Disease

Researchers have identified a potential drug candidate against enterovirus 71, a common cause of hand, foot and mouth disease in infants and young children. The compound of interest is a small ...

E. Coli Bacteria Offer Path to Improving Photosynthesis

Scientists have engineered a key plant enzyme and introduced it in Escherichia coli bacteria in order to create an optimal experimental environment for studying how to speed up photosynthesis, a holy ...

Technique Permits Convenient, Precise Optical Imaging of Individual Proteins

In a new study, researchers describe a method for examining proteins in keen detail. To do this, his group makes clever use of a phenomenon known as surface plasmon resonance (SPR), incorporating it ...

Your Cells Look Young for Their Age, Compared to a Chimp's

Many humans live to see their 80s, some even reach 100. But chimpanzees rarely make it past 50, despite sharing 99% of our genetic code. While modern medicine has added years to human lifespans, a ...

Biologists Create New Genetic Systems to Neutralize Gene Drives

Addressing concerns about gene drive releases in the wild, scientists have developed two new genetic systems that halt or eliminate gene drives after release. Created in fruit flies, the e-CHACRs and ...

A Scientific First: How Psychedelics Bind to Key Brain Cell Receptor

For the first time, scientists solved the high-resolution structure of these compounds when they are actively bound to the 5-HT2A serotonin receptor on the surface of brain cells. This discovery is ...
