Physicist Richard Lieu first explored the idea that gravity could exist without mass—now he’s got a new cosmological model that eschews the need for dark energy.

Human Brains Take Longer to Wire Up Than Simian Ones
Human brains make synaptic connections throughout much of childhood, and the brain’s plasticity enables humans to slowly wire them based upon experiences, contrary to how chimpanzees develop. Humans and chimpanzees share 98.8% of the same genes, but scientists have been looking for what drives the unique cognitive and social skills of humans.
A new study, which was published today in Genome Research, that examined brain samples from humans, chimpanzees, and macaques, collected from birth up to the end of their life span, has found some key differences between the expression of genes that control the development and function of synapses, which are the connections between neurons through which information flows.
Stimulating the Entorhinal Cortex of the Brain Boosts Memory
A team of neuroscientists at the School of Medicine at UCLA have demonstrated that they can strengthen memory in human patients by stimulating the entorhinal cortex. While studying patients with electrodes implanted in their brains, the researchers used a video game to test whether deep-brain stimul
