Doctors urged to reconsider controversial acne drug

Acne treatment including the highly effective acne medication isotretinoin should be made more readily available despite reports of its association with depression and teen suicide, a study recommends.

Two hormones drive anemonefish fathering, aggression

Two brain-signaling molecules control how anemonefish dads care for their young and respond to nest intruders, researchers report in a new study. Because there are many similarities in brain structure between fish and humans, the findings offer insight…

Resolving inflammation: Could it prevent memory loss in Down syndrome and Alzheimer’s?

Resolvins are lipids that ‘resolve’ the inflammation that normally follows injury or disease, returning the body back to normal. Therapeutic administration of one such resolvin can halt memory loss in a common preclinical model of Down syndrome, a find…

Brain-doping produced by your own body

Researchers have uncovered the mechanism by which Epo acts in nerve cells.

How associative fear memory is formed in the brain

Using a mouse model, researchers demonstrated the formation of fear memory involves the strengthening of neural pathways between two brain areas: the hippocampus, which responds to a particular context and encodes it, and the amygdala, which triggers d…

Protective brain-cell housekeeping mechanism may also regulate sleep

An important biological mechanism that is thought to protect brain cells from neurodegenerative diseases such as Alzheimer’s and Parkinson’s may also be involved in regulating sleep, according to new research.

To protect your brain, don’t be (too) kind!

Scientists demonstrated, through brain imaging and psycho-cognitive evaluations conducted over several years on a community-based cohort of elderly people, that certain personality traits protect brain structures against neuro-degeneration and Alzheime…

Scientists discover the mathematical rules underpinning brain growth

Life is rife with patterns. It’s common for living things to create a repeating series of similar features as they grow: think of feathers that vary slightly in length on a bird’s wing or shorter and longer petals on a rose.

BIN1 deficit impairs brain cell communication, memory consolidation

A new study has discovered that a lack of neuronal protein BIN1 leads to a defect in the transmission of chemical messages that activate brain cell communication allowing us to think, remember and behave. The preclinical research provides new insights …

Kids who blame themselves for mom’s sadness are more likely to face depression and anxiety

“Even if she doesn’t say it, I know it’s my fault that my mother gets sad.” Kids who believe comments like this – assuming blame for their mom’s sadness or depression – are more likely to face depression and anxiety themselves.
