Involuntary manslaughter charges aim to ‘hold individuals who contributed to this tragedy accountable’, prosecutor says.

Asteroid 2003 SD220 is making a close flyby of Earth on December 17, giving us a "Christmas asteroid" nearly a half-mile long. It won't be hazardous.

Researchers in Cardiff and the US work out how the Covid jab may be linked to the extremely rare clots.

The first of Australia’s new purpose-built quarantine facilities could be online by the end of the year but it’s unlikely most of the new beds being constructed across the country will be ready in time to assist with the Omicron threat.

Bipedal trackways discovered in 1978 at Laetoli site G, Tanzania and dated to 3.66 million years ago are widely accepted as the oldest unequivocal evidence of obligate bipedalism in the human lineage1–3. Another trackway discovered two years earlier at nearby site A was partially excavated and attributed to a hominin, but curious affinities with bears (ursids) marginalized its importance to the paleoanthropological community, and the location of these footprints fell into obscurity3–5. In 2019, we located, excavated and cleaned the site A trackway, producing a digital archive using 3D photogrammetry and laser scanning. Here we compare the footprints at this site with those of American black bears, chimpanzees and humans, and we show that they resemble those of hominins more than ursids. In fact, the narrow step width corroborates the original interpretation of a small, cross-stepping bipedal hominin. However, the inferred foot proportions, gait parameters and 3D morphologies of footprints at site A are readily distinguished from those at site G, indicating that a minimum of two hominin taxa with different feet and gaits coexisted at Laetoli. Reanalysis of bipedal trackways from Laetoli site A in Tanzania suggest that the footprints were made by a hominin that coexisted with at least one other hominin species.

The teenagers, aged 15, 16 and 17, from Binjari tested negative for the virus on Tuesday, but Chief Minister Michael Gunner says there will be consequences for the "dangerous and stupid" escape.
