Rare disease shares mechanism with cystic fibrosis
University of Michigan researchers have discovered that the same cellular mechanism involved in a form of cystic fibrosis is also implicated in a form of a rare disease called cystinosis. The mechanism cleans up mutated proteins. In cystinosis, a genetic disease, this allows cystine crystals to build up in the cell.

Study connects neural gene expression differences to functional distinctions
Researchers compared a pair of superficially similar motor neurons in fruit flies to examine how their differing use of the same genome produced distinctions in form and function. Figuring out how hundreds of different kinds of brain cells develop from their unique expression of thousands of genes promises to not only advance understanding of how the brain works in health, but also what goes wrong in disease.

Test to identify people at risk of developing acute myeloid leukaemia and related cancers
Test to identify people at risk of developing acute myeloid leukaemia and related cancers
The new platform, called -MN-predict-, will allow doctors and scientists to identify those at risk and to design new treatments to prevent them from developing these potentially lethal cancers. MN-predict makes it possible to identify at-risk individuals, and we hope it can become an essential part of future leukaemia prevention programmes.

DNA Chips as Storage Media of the Future
DNA Chips as Storage Media of the Future
In the form of DNA, nature shows how data can be stored in a space-saving and long-term manner. Würzburg's chair of bioinformatics is developing DNA chips for computer technology. The hereditary molecule DNA can store a great deal of information over long periods of time in a very small space. For a good ten years, scientists have therefore been pursuing the goal of developing DNA chips for computer technology, for example for the long-term archiving of data.

Training immune cells to remove ’trash’ helps resolve lung inflammation
Inflammation is a standard part of our bodies- immune system response. But sometimes this response becomes hyperactivated in our lungs, causing inflammation to continue unchecked, which can be fatal. Many deaths from COVID-19 have been due to excessive inflammation, which results in acute lung injury.

When proteins get stuck: unlocking the secrets to brain diseases
When proteins get stuck: unlocking the secrets to brain diseases
Biomedical engineers at the University of Sydney, in collaboration with scientists at Cambridge and Harvard, have developed sophisticated optical techniques to monitor how protein aggregates form at the nanoscale. Many diseases affecting the brain and nervous system are linked to the formation of protein aggregates, or solid condensates, in cells from their liquid form condensate, but little is known about this process.

Cells with an ear for music release insulin
Cells with an ear for music release insulin
"We will rock you": researchers are developing a gene switch that triggers insulin release in designer cells by playing certain rock and pop songs. Diabetes is a condition in which the body produces too little or no insulin. Diabetics thus depend on an external supply of this hormone via injection or pump.

Heat Sensor Protects the Venus Flytrap From Fire
Heat Sensor Protects the Venus Flytrap From Fire
The sensory hairs of the Venus flytrap contain a heat sensor that warns the plant of bush fires. It reacts to rapid temperature jumps, as Würzburg researchers have discovered. The Venus flytrap can survive in the nutrient-poor swamps of North and South Carolina because it compensates for the lack of nitrogen, phosphate and minerals by catching and eating small animals.
