New highly sensitive test for dengue virus developed using DNA star

Researchers have developed a new method for detecting and destroying the dengue virus that could be adapted for other viruses.

Scientists record assembly of ribosomes in real time

A team of scientists from Scripps Research and Stanford University has recorded in real time a key step in the assembly of ribosomes--the complex and evolutionarily ancient "molecular machines" that make proteins in cells and are essential for all life forms.

DNA-modulated liquid droplets may explain how prion proteins clump

Researchers at the Federal University of Rio de Janeiro, in Brazil, have identified that the interaction between prion proteins and DNA may be behind the formation of protein amyloid aggregates and of the emergence of neurodegenerative diseases such as Creutzfeldt-Jakob disease and other spongiform encephalopathies.

Scientists investigate the dynamics of molecular changes in gliomas

Until relatively recently, cancer was viewed as a single disease with sub-types based on where in the body it arose.

Wound healing events in mucous tissues could guard against AIDS

Wound healing events in mucous tissues during early infection by Simian Immunodeficiency Virus, or SIV, guard some primate species against developing AIDS, a recent study has learned.

Extra DNA scooped up alongside cancer-causing genes helps drive tumor growth

One of the ways a cancer-causing gene works up enough power to turn a normal cell into a cancer cell is by copying itself over and over, like a Xerox machine.

Doughnut-shaped circles of ecDNA provide tumor cells with a malignant twist

Deoxyribonucleic acid or DNA encodes information, not only in its sequence but also in its shape.

Researchers develop breakthrough in marine sponge cell culture

Vertebrate, insect, and plant cell lines are important tools for research in many disciplines, including human health, evolutionary and developmental biology, agriculture and toxicology. Cell lines have been established for many organisms, including freshwater and terrestrial invertebrates.

Neuroscientists decode how visual cues can reorganize the activity of compass neurons

If you've ever woken up in the middle of the night to go to the bathroom and stumbled around in the dark, banging into walls or dressers in a room you've walked through countless times, you've experienced the effects of inadequately calibrated neurons.

Researchers detect photoinitiators in human breast milk

Photoinitators (PIs) are compounds used in the ink of many types of food packaging. The substances have been shown to migrate into food and, when consumed, show up in human blood serum.

Label-free multimodal imaging platform enables non-invasive study of cell cultures

Most analytical methods in biology require invasive procedures to analyze samples, which leads to irreversible changes or even their destruction.

Circular DNA found in cancer cells supports their survival and resistance

A new study uncovers the role of the circular, 3D shape of extrachromosomal DNA in augmenting mutant oncogenes in cancer cells.

Applying a Proteomics-based Approach to the Clinic

Matthias Mann explains why applying proteomics-based technologies such as timsTOF could accelerate the diagnosis and prediction of human disease.

New database helps identify therapeutic targets to fight infectious diseases

Infectious diseases are caused by pathogenic microorganisms capable of entering, colonizing and growing within a host organism, thus producing an infection. Bacterial infections have been on the rise worldwide in recent years, but many mechanisms underlying bacterial pathogenesis are still poorly understood.

Scientists grow complex organoids in the lab

Scientists at the University of Würzburg have successfully produced human tissues from stem cells. They have a complexity similar to that of normal tissue and are far superior to previous structures.

Research findings can be used in antiviral development against enterovirus infections

Despite their prevalence, there are no antivirals on the market against enteroviruses, and vaccines have been developed only against couple of serotypes. The production of vaccines against all enterovirus serotypes is not feasible, and so antiviral drugs may be the solution for most of the enterovirus infections.
