An illustration of interactions between the gut and the brain.

The Gut–Brain Axis May Not Operate as Previously Thought

New information on how the gut and brain communicate has been uncovered by Flinders University researchers in a development that could influence how we make and use certain drugs, such as antidepressants.

Cholesterol Clumps Disrupt the Pain Relief We Feel From Applying Pressure

Physical pressure on an injury can reduce pain signals, but new research shows that cholesterol clumps in cell membranes can interfere with that process.

Exposing Cancer Cells to Secondhand Smoke Decreases Chemotherapy Efficacy

People who are diagnosed with head and neck cancer often receive a standard type of chemotherapy as part of their treatment. If they are exposed to secondhand smoke during chemotherapy the treatment may be far less effective at killing cancer cells.

Trabid Protein’s Role in Microcephaly Identified for the First Time

A new study pinpoints how mutations in a protein involved in neuronal development can contribute to microcephaly, which causes abnormal brain development.

Sea Lampreys Rewrite Our Understanding of Vertebrate Brain Evolution

A new study from the Krumlauf laboratory shows that the hindbrain of humans and jawless sea lamprey is built using a similar molecular and genetic toolkit. This discovery implies that these molecular features were present in the common ancestor of all vertebrates today.

Research Unveils How the Small Intestine Changes Size

Resizing of the intestine is a highly conserved strategy employed by a wide range of organisms to cope with fluctuation in nutrient availability. New research identifies one of the signaling pathways implicated in this process.

The Surprising Strength of Babies' Immune Cells

For a long time, it has been thought that a baby’s immune system is far weaker than that of an adult due to limited pathogen exposure. However, a recent paper, published in Science Immunology, has questioned these beliefs.

More Realistic Synthetic Mini-Hearts May Help Study Cardiovascular Disease

Thanks to advancements in the development of patented synthetic human-like hearts first created at Michigan State, researchers can study human heart development and congenital heart disease on highly accurate models.
