Detection of electrical signals in fungal mycelia in response to external stimuli

mycolabadmin

Scientists developed a new tool to detect electrical signals produced by fungal mycelia, the root-like networks of fungi. Using special circuit boards with tiny sensors and a noise-reducing cage, they successfully measured electrical activity in growing fungi that varied when exposed to toxic chemicals. These findings suggest fungi use electrical signals to communicate within their networks, similar to how nerve cells communicate in animals.

The Role of Acid-Sensing Ion Channel 1A (ASIC1A) in the Behavioral and Synaptic Effects of Oxycodone and Other Opioids

mycolabadmin

This study examines how a specific type of brain channel called ASIC1A affects how the brain responds to opioid drugs like oxycodone and morphine. Researchers found that mice without this channel showed stronger attraction to opioid-paired locations and had unusual changes in brain connections related to opioid use. The findings suggest that targeting ASIC1A could potentially be a new way to treat opioid addiction by reducing the brain’s sensitivity to these drugs.

Functional relationship between peripheral thermosensation and behavioral thermoregulation

mycolabadmin

This review explains how your body senses temperature through specialized proteins called TRP channels, which detect hot and cold stimuli. These temperature-sensing proteins help you and other animals regulate body temperature by triggering behaviors like seeking warmth or coolness. Importantly, the review shows that the fatty acid composition of cell membranes can fine-tune how sensitive these temperature sensors are, offering insights into how organisms adapt to different thermal environments.
