Nuclear location helps control gene activity during brain development

A study of developing human brain tissue suggests that genes switch on more strongly when they move from the nucleus’s edge toward structures that contain proteins involved in making and processing RNA.

How thirteen-lined ground squirrels illuminate retinal development

In most mammalian retinas, rods outnumber cones. But that ratio is flipped in ground squirrels, a quirk that helps Seth Blackshaw explore how retinal cells develop their identities.

Gene activity in human cortex shows striking sex differences

The results mark a “dramatic shift” in how neuroscientists think about sex differences, and they may help explain sex biases in certain neurodegenerative and neurodevelopmental conditions.

Grant review needs reform. How about we add an element of chance?

A process that uses a lottery system saves time, reduces strategic resubmission and accepts that, above a quality threshold, luck has always played a part in science funding.
