Can we stop neurons signaling their own death?
For over 150 years, it was believed axons die independently when injured by stroke, brain injury, or disease. A new study challenges this idea, suggesting axons coordinate their own destruction. Knowing this, a drug may be able to block axons from receiving the signal to degenerate. Then damage to healthy cells could be slowed or stopped.

GABA may be key to regenerating human retinas
If you were a fish and your retina was damaged, it could repair itself and your vision would be restored in a few weeks. Sadly, human eyes don't have this ability - yet.

Will mammals ever be able to regenerate tissues?
Regeneration differs across species. Fish and amphibians re-grow appendages such as limbs, tails, and fins. But mammals, including humans, cannot restore injured organs. Finding out what molecular mechanisms underlie the regeneration of lower vertebrates may help us restore complex organs in humans, a clinical goal of the future.

What is a "brain organoid" and why do we need it?
Researchers have already grown "cerebral organoids" in labs — clusters of cells that self-organize into small brain-like structures called "brain organoids." Now "forebrain" centers in these clusters of cells seem to be recreating neuron timing and differentiation just like cells in an actual brain.

Male infertility may be due to failure of calcium signal
A key protein in sperm causing some men to be infertile, appears to be phospholipase C zeta or PLC-zeta. When PLC-zeta is ineffective due to poor volume or a mutation, sperm fail to initiate calcium signalling and egg development. The discovery could enable early diagnosis and treatment.
