According to recent studies, bones maintain a lively metabolism and closely interact via nerves with the brain. But whether endocrine hormones also play an important role in brain-bone talk has been unclear. Researchers from...
Study reveals how patients’ smoking history changes evolution of lung cancer
by Walter and Eliza Hall Institute This immunofluorescence image shows the presence of a specific subset of T cells (tissue-resident memory T cells, TRM) in the lung of smoker patients. The TRM cells are represented here in aqua and red, the lung airways are depicted in pink, and the cell nuclei are depicted in dark blue....

Smart dressing changes color if wounds are infected
By Ben Coxworth April 19, 2023 PhD students Elisa Zattarin and Olof Eskilsson work with the color-changing dressingOlof Planthaber It’s ironic that in order to check if a wound is becoming infected, doctors may end up setting back the healing process by prematurely removing the dressing. An experimental new dressing is designed to help, as...
Obesity: Could a hormone predict whether people will be able to maintain weight loss?
Maintaining weight loss may be influenced by the levels of a particular hormone. Ivan Andrianov/Stocksy Obesity is linked to many health conditions and is associated with the leading causes of death globally. Attempts to lose excess weight through lifestyle changes are often thwarted by the fact that the majority of people who do manage to...
Famous ‘homunculus’ brain map redrawn to include complex movements
Max Kozlov The homunculus or ‘little man’ is a foundational concept in neuroscience. Credit: Colin McConnell/Toronto Star via Getty The bizarre-looking ‘homunculus’ is one of neuroscience’s most fundamental diagrams. Found in countless textbooks, it depicts a deformed constellation of body parts mapped onto a narrow strip of the brain, showing the corresponding brain regions that control...
Earpiece zaps nerves to rewire the brain and speed stroke recovery
By Michael Irving April 19, 2023 A new wearable device can stimulate the vagus nerve to help speed up patient rehabilitation after a stroke Depositphotos Engineers at ETH Zurich have developed a wearable system that can help patients regain movement and mobility after a stroke. The system consists of a motion-sensing watch and an earpiece...
Clear chemical connection between physical activity and brain health
By Bronwyn Thompson April 18, 2023 Scientists unlock key chemical mechanisms that link brain health with muscle use Depositphotos The link between physical activity and brain health is not new, with many studies showing how exercise can boost function, from easing depression to staving off cognitive decline. Now, scientists have shown in cell studies that the connection may be more direct, which opens the door to...
