Studying red junglefowl chicks, researchers conclude impulsivity is linked to both gene expression and early life experiences.
Researchers have identified several novel functional mechanisms related to the inner hair cells of the ear. The findings may upend numerous longstanding theories about the working anatomical organization and workings of the ear, as well as provide new avenues for the development of technologies to improve hearing.
A newly developed ion pump can deliver cancer-fighting drugs more accurately, and with fewer side effects than conventional chemotherapy, to those with glioblastoma brain cancer.
Microglia appear to play a key role in inflammation-associated depression.
Fatty acid amide hydrolase (FAAH) inhibitors, a form of medication that boosts endocannabinoids, may be helpful in the treatment of PTSD. FAAH inhibition can improve the recall of fear extinction memories. The drugs could also help treat stress and other psychological disorders.
Pain signaling occurs much faster than previously believed. Researchers report thickly myelinated nerves contribute to pain processing speeds.
Researchers identify an interspecies correlation between hair cortisol concentrations in humans and dogs during summer and winter months. The cortisol levels were not affected by the amount of activity the dog had during these periods. The study reveals a seasonal effect in higher cortisol levels between humans and animals, and human personality traits significantly affected the dog's level of stress. Findings suggest that dogs often mirror the stress levels of their owners.
Connexins play a critical role in the uptake and transfer of Parkinson's related proteins from one cell to another. The findings may help with the development of new treatments for Parkinson's disease.

··4 min readResearchers have developed an evolvable electrochemical transistor which has the ability to learn. The transistor is equipped with the ability for both long and short term memory. The new technology is a major step towards machine learning that utilizes organic electronics, the researchers report.
A new neuroimaging study reveals brain activity is reduced when we experience self touch, as opposed to the touch of another person. The findings shed light on how the brain is able to distinguish between tactile sensations generated by the touch of another and personal touch.
Researchers say melanocortin 4 receptors may play a role in unease and reward. The study reports dopamine levels fell in the reward system of mice when the animal experienced something unpleasant. However, in mice lacking the melanocortin 4 receptor, dopamine levels increased slightly following a negative experience.
Researchers reveal how molecular alterations in the brain are linked to behaviors central to addiction.
