The Immune Chain Reaction That Raises Colon Cancer Risk in IBD

A hidden immune cascade linking the gut and bone marrow may explain how IBD turns inflammation into colon cancer.

Scientists at Weill Cornell Medicine have identified a complex immune process in the gut that may help explain why people with inflammatory bowel disease (IBD) face a much higher risk of colorectal cancer. The preclinical study shows how a specific immune signal can trigger a wave of white blood cells from the bone marrow into the gut, creating conditions that support tumor growth. The findings also suggest new approaches for detecting disease activity, tracking risk, and developing future treatments.

Detection of THC Impairment Using Functional Near-Infrared Spectroscopy

Among adults receiving oral THC, portable fNIRS scans detected impairment with higher accuracy and fewer false positives than field sobriety tests, supporting fNIRS as a more objective approach for cannabis impairment detection.


This crossover trial compares the accuracy of resting-state functional near-infrared spectroscopy vs standard field sobriety testing to detect ∆9-tetrahydrocannabinol (THC) impairment among adults who use cannabis.

Missing Link Between Parkinson’s Protein And Damage to Brain Cells Discovered

An investigation by researchers from Case Western Reserve University School of Medicine in the US has filled in a missing link between the toxic build-up of proteins in the neurodegenerative condition Parkinson’s disease and the death of critical brain cells.

The result of three years of research, the discovery connects alpha-synuclein proteins to a breakdown in mitochondrial function, both previously linked to Parkinson’s.

“We’ve uncovered a harmful interaction between proteins that damages the brain’s cellular powerhouses, called mitochondria,” says neuroscientist Xin Qi.
