How the brain processes sensory information from internal organs

Most of us think little of why we feel pleasantly full after eating a big holiday meal, why we start to cough after accidentally inhaling campfire smoke, or why we are hit with sudden nausea after ingesting something toxic. However, such sensations are crucial for survival: they tell us what our bodies need at any given moment so that we can quickly adjust our behavior.

Low-cost disease diagnosis by mapping heart sounds

Researchers develop a method to identify aortic valve dysfunction using complex network analysis that is accurate, simple to use, and low-cost. They used heart sound data to create a complex network of connected points, which was split into sections, and each part was represented with a node. If the sound in two portions was similar, a line was drawn between them. In a healthy heart, the graph showed two distinct clusters of points, with many nodes unconnected. A heart with aortic stenosis contained many more correlations and edges.

AI may come to the rescue of future firefighters

In firefighting, the worst flames are the ones you don't see coming. Amid the chaos of a burning building, it is difficult to notice the signs of impending flashover -- a deadly fire phenomenon wherein nearly all combustible items in a room ignite suddenly. Flashover is one of the leading causes of firefighter deaths, but new research suggests that artificial intelligence (AI) could provide first responders with a much-needed heads-up.

Multiple sclerosis drug works in a surprising way

Drugs called interferon betas are common treatments for multiple sclerosis (MS), reducing relapses and slowing motor function decline. Interferon beta, a protein known to contain a zinc binding pocket, is thought to reduce proinflammatory molecules and even increase production of anti-inflammatory species in MS patients. But researchers now report that the molecule reduces the binding of three components -- zinc, C-peptide and albumin -- to red blood cells.

Cardiovascular diseases remain a leading cause of death around the world. A primary contributor to these afflictions is high blood pressure, or hypertension. While treatments exist for the condition, which affects tens of millions of Americans, these remedies are not without side effects, and some variants of the disorder are treatment-resistant. The need for more effective therapies to address hypertension-related disease is therefore acute. To accomplish this however, biologists need more detailed maps of the mechanisms underlying cardiovascular regulation. One such regulator is a protein receptor that sits atop cardiovascular cells, acting as a conduit for messages that are transmitted when specific hormone molecules bind with them.
