How carrageenan affects insulin resistance

A randomized controlled trial found that carrageenan, a common food additive, may cause subclinical inflammation and insulin resistance in overweight individuals, mediated by gut permeability and inflammation. Effects were linked to BMI but not observed in non-overweight participants during short-term exposure.

Inflammation and organ damage in severe COVID-19 tied to mitochondrial dysfunction

Severe COVID-19 arises in part from the SARS-CoV-2 virus's impact on mitochondria, tiny oxygen-burning power plants in cells, which can help trigger a cascade of organ- and immune system-damaging events, suggests a study by investigators at Weill Cornell Medicine, Johns Hopkins Medicine, Children's Hospital of Philadelphia, and the University of Pittsburgh School of Medicine, along with other members of the COVID-19 International Research Team.

Loss of empathy in frontotemporal dementia linked to brain activity changes

Patients with frontotemporal dementia often lack the ability to empathize. A study at Karolinska Institutet has now shown that these patients do not show the same brain activity as healthy individuals when they witness the pain of others, a finding that it is hoped will increase understanding of this specific dementia disease.

Biocompatible liquid ink enables scalp-printed electrodes for non-invasive EEG

For the first time, scientists have invented a liquid ink that doctors can print onto a patient's scalp to measure brain activity. The technology, presented December 2 in the Cell Press journal Cell Biomaterials, offers a promising alternative to the cumbersome process currently used for monitoring brainwaves and diagnosing neurological conditions. It also has the potential to enhance non-invasive brain-computer interface applications.
