A "Liquid Health Check" Could Help Predict Disease Risk
An international team of researchers from the UK and USA has shown that large-scale measurement of proteins in a single blood test can provide important information about our health and can help to predict a range of different diseases and risk factors.

Teaching People To Control Their Brainwaves Can Boost Their Attention, Too
Having trouble paying attention? A study found that people can enhance their attention by controlling their own alpha brain waves based on neurofeedback they receive as they perform a particular task.

Neuroscience 2019, the world’s biggest conference of brain science, finished just over a month ago. In the wake of some particularly inflammatory headlines, we take a closer look at whether claims that new model systems for studying the brain could produce sentience in a jar have any truth to them.
Estimates suggest that more than 30 million people worldwide are affected by sepsis each year, with up to six million of these dying from the condition. We recently spoke to Elena Sukhacheva, Director Medical and Scientific Affairs at Beckman Coulter, to learn about some of the challenges of diagnosing sepsis early, and how measuring Monocyte Distribution Width can be used as a sepsis biomarker to aid the process.
Diffuse intrinsic pontine glioma (DIPG) is a rare, deadly childhood brain cancer. Here, a confocal micrograph shows DIPG cells, grown from patient cells, in culture. The cells are expressing several proteins, including: DAPI (blue, in the cell nuclei); vimentin (red, a protein marker of neural stem/precursor cells and glioma cells); and Nestin (green, also a protein marker of neural stem/precursor cells and glioma cells).
