Tarantula Toxin Could Help To Design Drugs for Chronic Pain
News Nov 24, 2020A new high-resolution cryo-electron microscopy study shows how the Chinese tarantula stinger quickly locks voltage sensors on sodium channels, the tiny pores on cell membranes that create electrical currents and generate signals to operate nerves and muscles. This discovery provides a molecular template for future structure-based drug design of pain therapeutics.

Gut-Brain Axis Influences Inflammation in Multiple Sclerosis
News Nov 23, 2020A research team has discovered a connection between the intestinal flora and sites of inflammation in the central nervous system in multiple sclerosis. A specific class of immune cell plays a central role in this newly identified gut-brain axis. The discovery could pave the way for new treatments for MS that target the intestinal flora.
Wearable Cuff Could Predict Movement Disorders in Babies
News Nov 23, 2020The research, carried out using a wearable cuff, provides a new method for monitoring movements in babies, and new insights into how babies' reflexes - like kicking - develop. These insights and the cuff could also be used to spot early signs of motor disorders such as cerebral palsy.
Do Neural Networks Get Fooled by Visual Illusions?
News Nov 23, 2020A convolutional neural network is a type of artificial neural network in which the neurons are organized into receptive fields in a very similar way to neurons in the visual cortex of a biological brain. A new study examines the phenomenon of visual illusions in convolutional networks compared to their effect on human vision
