Chemical flasks and inconvenient chemostats for cultivation of bacteria are likely soon to be discarded. Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw were first to construct a microfluidic system allowing for merging, transporting and splitting of microdroplets.

Abdominal pain, fever, diarrhoea - these symptoms could point to an infection with the bacterium Yersinia. The bacterium's pathogenic potential is based on a syringe-like injection apparatus called injectisome. For the first time, researchers have unraveled this molecular syringe's spatial conformation.

First produced only in the past decade, human induced pluripotent stem cells (iPSCs) are capable of developing into many or even all human cell types. In new research, scientists reprogrammed skin cells from patients with rare blood disorders into iPSCs, highlighting the great promise of these cells in advancing understanding of those challenging diseases - and eventually in treating them.

Researchers have developed a new method that can look at a specific segment of DNA and pinpoint a single mutation, which could help diagnose and treat diseases such as cancer and tuberculosis. These small changes can be the root of a disease or the reason some infectious diseases resist certain antibiotics.

A small plastic strip can do 'weight training' to effortlessly lifts many times its own weight, driven by cyclic changes in the humidity of the surrounding air. This strong 'artificial arm' is based on the interaction between microgels and a layer of polycations that shrinks as it dries.

Human glioblastoma multiforme, one of the most common, aggressive and deadly forms of brain cancer, is notoriously difficult to study. Now a team of engineers has developed a three-dimensional hydrogel that more closely mimics conditions in the brain than other platforms used to study brain cancer. In a paper in the journal Biomaterials, the researchers describe the new material and their approach, which allows them to selectively tune up or down the malignancy of the cancer cells they study.

Novel microchips imitate the brain's information processing in real time. Neuroinformatics researchers demonstrate how complex cognitive abilities can be incorporated into electronic systems made with so-called neuromorphic chips: They show how to assemble and configure these electronic systems to function in a way similar to an actual brain.
