Fetuses may be able to see more than previously believed

By the second trimester, long before a baby's eyes can see images, they can detect light.

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.

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.

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.

TARA's organ-on-a-chip technology can directly measure in vivo cardiac performance, study shows

TARA Biosystems, Inc. today reported in vivo and in vitro functional data from a study of investigational candidate, MYK-491, showing that TARA's human iPSC-derived organ-on-a-chip technology can directly measure in vivo cardiac performance.

Directional control of protocell's movement could lead to precision drug delivery

Synthetic protocells can be made to move toward and away from chemical signals, an important step for the development of new drug-delivery systems that could target specific locations in the body.

Study uncovers how the molecule-sorting station in our cells is formed and maintained

The cells in our body are workshops that continuously operate to produce and process substances to keep us going. When a substance enters a cell for processing, it is surrounded by a portion of the cell's outer membrane to form a sac.

Study unravels how insulin interacts with its receptor

Since the discovery of insulin nearly 100 years ago, scientists have explored how it interacts with its receptor with the goal of improving the ability of therapeutic insulins to mimic the way insulin works in the body.

New technique enables the study of transporter proteins at a single-molecule level

Like a boat helping passengers cross a river, transporters move substances across cell membranes. This process is fundamental to the healthy functioning of cells in life forms from bacteria to humans.

Tulane virus needs intracellular calcium to replicate

Some gastrointestinal viruses need calcium. They need calcium ions to carry out several essential aspects of viral life, such as entry into host cells, genome replication and building new viruses to invade other cells. The cells invaded by viruses also use calcium. They use it as signals to regulate many of the cells' own processes, but viruses can takeover cellular calcium signaling to satisfy their own needs.
