Beating the previous record for the oldest known cave artwork by at least 15,000 years, a hand stencil in an Indonesian cave might shed light on when early humans migrated to Australia

Extraordinary fossils of 518-million-year-old jawless fish, among the earliest known vertebrates, appear to show that these animals had two pairs of eyes

Newly discovered rock art sites in Sulawesi, Indonesia, that date to nearly 68,000 years ago are thought to be the oldest rock art in the world, pre-dating Neanderthal hand stencils in Spain by 1100 years

A fossil discovery in northern Ethiopia expands the known range of Paranthropus, a genus of strong-jawed hominins that lived around 2 million years ago, and suggests they lived in a range of habitats

The light-sensitive tissue of birds’ eyes is not supplied with oxygen by blood vessels – instead, it powers itself with a flood of sugar, and this may have evolutionary benefits

The U.S. space agency will quit funding several independent science advisory groups this year

Deer antler rubs and hoof scrapes change how parts of the forest reflect short-wavelength light, perhaps leaving a glowing signal

Back in 2014, the Atacama Large Millimeter/submillimeter Array (ALMA) captured an image of a young protoplanetary disk around a young star named HL Tauri. The image showed gaps and rings in the disk, substructures indicating that young planets forming there. This meant that planet formation began around young stars a lot sooner than thought. ALMA is continuing its investigation of protoplanetary disks in its ARKS survey (ALMA survey to Resolve exoKuiper belt Substructures).

Material science plays an absolutely critical role in space exploration. So when a new type of self-healing composite is announced, it’s worth a look–especially when the press release specifically calls out its ability to repair microtears associated with micrometeoroid impacts on satellites. It sounds like just such a composite material was recently invented at North Carolina State University - and it’s even already been spun out into a start-up company.
