Through 'heart-on-a-chip' technology - modeling a human heart on an engineered chip and measuring the effects of compound exposure using microelectrodes - researchers hope to ensure potentially lifesaving new drugs are safe and effective while reducing the need for human and animal testing.
Researchers hope that the stem cells will possibly form new disc cartilage once injected into a damaged disc. A new study on three sick German shepherds demonstrates that a treatment with the body's own stem cells are well tolerated - an important first step.
Scientists present in atomic detail how specific bacterial enzymes, known as kinases, confer resistance to macrolide antibiotics, a widely used class of antibiotics and an alternative medication for patients with penicillin allergies. The study shows for the first time how these kinases recognize and chemically destroy macrolide antibiotics.
Using fluorescence probes, researchers designed a technique that shows mRNA when it comes in contact with ribosomes. They used this method to record the synthesis of proteins and to measure cellular responses to iron.
Using human skin cells, neurobiologists have created a method to generate one of the principle cell types of the brain called microglia, which play a key role in preserving the function of neural networks and responding to injury and disease.
A common insect larva that eats beeswax has been found to break down chemical bonds in the plastic used for packaging and shopping bags at uniquely high speeds. Scientists say the discovery could lead to a biotechnological approach to the polyethylene waste that chokes oceans and landfills.
