Researchers have uncovered the molecular mechanism triggered by the presence of tetrahydrocannabinol (THC) – the cannabinoid that causes people to feel the euphoria or “high” associated with cannabis – in the bloodstream that accelerates cancer growth in patients with HPV-positive head and neck cancers.

Certain probiotic bacteria – microorganisms that can improve the state of our gut's health – are capable of slashing levels of a protein related to Parkinson's disease, suggests new research conducted in roundworm models of the disease.

Researchers at Vanderbilt University Medical Center have published a study suggesting that brain receptors activated by marijuana can be targeted to cut stress. The scientists used a mouse model of stress in their study, where they showed that a molecule that activates the receptors could reduce anxiety-linked connections between two distinct brain areas.

Researchers have identified a peptide that can disrupt protein complex that is elevated in PTSD patients, preventing recall or encoding of fear memories in early tests.

Researchers have revealed that living in neighborhoods with high risk of lead exposure is associated with differences in brain structure in some children.

Pronounced maternal stress, anxiety and depression in women with a diagnosis of a major fetal heart problem can result in impaired development in key brain regions before babies are born, according to new research.

Storing and retrieving memories is among the most important tasks our intricate brains must perform, yet how that happens at a molecular level remains incompletely understood. A new study sheds light on one element of that memory storage process, namely the storage and retrieval of a type of hardwired long-term memory.

Results of a new study investigating the dorsal anterior cingulate cortex (dACC) has provided new insight into how surprise is linked to motivational behavior.

A new study revealed how machines can solve complex problems just as accurately as theoretical physicists, but significantly faster.

A molecule, 2-arachidonoylglycerol, also referred to as “2-AG”, protects against stress by reducing “anxiety-causing” connections between two particular regions in the brain – 2-AG elicits its effect by activating the same receptors as cannabis.
