Play develops similarly in chimps and humans
The researchers found that chimpanzee solitary play peaks in infancy, and the time spent in social play is about the same between infants and juveniles. But the type of social play changed quite a bit as the animals grew up, in terms of measures like complexity and playmate choice.

“Dark matter” mystery deepens
Like all galaxies, most astronomers believe ours is filled with a strange, invisible substance that betrays its presence only through its gravitational pull. The galaxy’s stars would fly apart without this so-called dark matter holding them together. But the nature of “dark matter” is a riddle—and a new study has only deepened the mystery.

“Junk DNA” may help explain human-chimp differences
For years, scientists thought an explanation would soon turn up for the vast differences between humans and their closest relatives among the animals, such as chimpanzees. The difference must be in the genes, biologists reasoned. But this hypothesis ran into trouble when it later emerged that human and chimp genes are nearly identical.

Embryonic solar system brimming with water
New findings suggest an embryonic solar system contains thousands of oceans’ worth of water — so water-covered planets like Earth may be common.

Seeing An Object Vs Focusing Attention On It
Our brain's primary visual cortex probably focuses our attention rather than recognising what we see, a new study has found.

Shape-Shifting Material Reacts To Radiation
Physicists have engineered a new kind of artificial substance, called a magnetoelastic metamaterial, that can change its structure in response to varying levels of electromagnetic radiation, such as microwaves or visible light.
