Big US-style trucks are killing more pedestrians in Australia – our research proves it
Pedestrians are more likely to be killed by heavier cars – and even more so if the vehicle is taller, Australian-first research has found.

I'm losing my patience with these political commentators explaining that impeachment is one of the tools Congress has in dealing with a rogue president. Tools? F that, it's their constitutional duty. They must impeach a rogue president.

I taught US history and government for many years and was always careful not to include a current president in any discussion of presidential rankings. We need time for evaluation and perspective, I'd say. But the past year and a half have been too stark to ignore. Worst. President. Ever.

Surgeries Performed in Professional Australian Cricketers 2015–2024 - Indian Journal of Orthopaedics
Aim A study describing the distribution and rate of surgical operations performed in professional Australian cricketers, both male and female, over a decade. Methods Cricket Australia Athlete Management System was searched for consultations including terms that might reference whether surgery had been performed. Surgeries were any procedure performed in a hospital or day care facility, including non-orthopaedic surgeries. Results There were 3419 player years studied between 2015 and 2024, yielding 447 surgeries, a rate of 13.1 surgeries per 100 player years, the majority of which were musculoskeletal (orthopaedic) procedures. The most common procedures were: knee arthroscopy (1.61/100 player years), wrist hand/finger fracture fixations (1.52), shoulder reconstruction (0.91), ankle posterior impingement procedures (0.44) and knee ACL reconstructions (0.41). The rates of surgery in male (12.7) and female (13.5) players were similar. The rate of surgery in male players was lower than a previous audit a decade ago (19.6 which excluded non-musculoskeletal procedures, P < 0.001) with the surgeries being performed less often including knee arthroscopy, ankle posterior impingement procedures and shoulder arthroscopy (all P < 0.001). Discussion/conclusions There is a general consistency in the rate of surgical procedures in professional Australian cricketers, although rates for the recent decade have dropped compared to the one prior in male players. Rates of surgery between male and female cricketers are very similar, and rates are lower than in the football codes in Australia but higher than the general population.

Rob Hirst was a force of nature, a born showman who led Midnight Oil from the back
Phenomenal drummer and percussionist was an equally accomplished songwriter who embodied the band’s bloody-minded spirit * Rob Hirst, Midnight Oil drummer and founding member, dies aged 70 Ask Midnight Oil fans what drummer Rob Hirst will be remembered for, and the most likely answer will be his drum solo on Power and the Passion, one of the band’s big early hits. It’s an explosive minute of almost literal madness – Hirst was on the verge of a breakdown when the track was recorded in 1982, for their breakthrough album 10, 9, 8, 7, 6, 5, 4, 3, 2, 1. Drum solos had, by that time, become a symbol of rock excess. But this wasn’t just another vulgar display of virtuosity. It was more musical than most guitar solos, enhancing a song already full of moving parts. Live, much of it was played on a corrugated iron water tank Hirst retrieved from the desert on the Oils’ Blackfella/Whitefella tour in 1986. Continue reading...
