Scientists have uncovered how the brain's far-reaching Behavioral Activation System, along with chemical drivers, can override other cognitive processes when we experience romantic love, driving that all-consuming focus on the object of our affection.
-
Slowing down the dreaded aging process interests everybody, and now scientists have uncovered a new pathway to doing so. The team identified a feedback loop in the brain, and found that ramping up its activity helped mice live longer and healthier.
-
Researchers have provided the first direct evidence explaining the function of sleep. They demonstrated that sleep resets the brain’s ‘operating system,’ undermined during waking, returning it to an ideal state to optimize thinking and processing.

An effective single-dose, long-term treatment for anxiety could be within reach, with the phase 2b clinical trial of MM-120 reported to have passed the stage with flying colors.
-
In a finding that could have a significant impact on personalized medicine, scientists have identified five blood compounds linked to suicidal ideation. It could prove crucial in assessing risk factors and for new targeted treatment of depression.

In the largest study of its kind, researchers have found that sharing a childhood home with a kitty can more than double the risk of later developing schizophrenia-like disorders. However, in what may surprise some, it's not entirely the cat's fault.
-
Restoring damaged nerves caused by multiple sclerosis could be within reach, thanks to a breakthrough in small molecule drug research. Scientists say their new compound has a "stunning effect on rescuing myelin," which would be pivotal in reversing MS.
-
Scientists have solved the mystery of which protein triggers the onset of many cases of frontotemporal dementia, paving the way for more effective early diagnosis of the degenerative disease and the development of potentially life-changing treatment.
-
In a feat only a few non-human animals have accomplished so far, a common dark-furred mouse has passed what’s known as the mirror self-recognition test. Backed by supporting genetic cues, this suggests mice can actually recognize themselves.
-
A groundbreaking study has mapped dopamine, deep inside the brain, in real time. Surprising researchers, the "pleasure neurotransmitter" is more complex than earlier thought, shaping our brain to make better decisions based on prior experience.
-
Most of us have woken up with an aching back after a sleepless night, only for that pain to then keep us awake the next night. Now Harvard scientists have discovered a possible link between pain and poor sleep, and maybe even a way to break the loop.

Multiple sclerosis (MS) is a debilitating disease with few treatment options. But in a new clinical trial, scientists have tested a promising new therapy involving injections of stem cells, which seems to slow progression of the disease.
