Richmond coach Damien Hardwick had said on Wednesday that Martin was on course to return in the round of 20 against the Brisbane Lions, which is when he expects key forward Tom Lynch (hamstring) to return. The Tigers tweeted they would not provide further updates on Martin until needed. Talisman Martin has only played eight games this season. The 31-year-old took personal leave after the first round and missed six games, coming back with a bang in round eight when he hit two goals in the win over Collingwood. With AAP ‘We don’t look past our noses’: McRae says Grundy’s talent is being underestimated Roy Ward Collingwood coach Craig McRae thinks few in the AFL world have short memories when it comes to ruckman talent Brodie Grundy following a knee injury in April.

The former federal minister who oversaw the introduction of carbon prices in Australia has backed calls for policies such as insurance to help fix the crisis plaguing the country’s largest power grid. Key points: Former climate change minister Greg Combet has backed plans for capacity markets to help repair networks The proposal was pursued in the midst of skyrocketing prices and warnings of blackouts in the national electricity market Mr Combet said the policy was needed to help Australia transition to 100 per cent renewable energy Greg Combet, a former union leader who served as climate change minister in the Gillard government, said ideology needed to be removed from debates about how to solve problems affecting national electricity markets. Mr Combet said businesses and households – especially the vulnerable – were suffering amid skyrocketing prices and rolling blackout warnings as the system struggled to cope with demand. While he blamed the “chaos” at...

By Indranil Banik, Postdoctoral Researcher from Astrophysics, University of St Andrews 10 July 2022 Dark matter is proposed to explain why stars at the far edges of galaxies can move faster than Newton predicted. An alternative theory of gravity may be a better explanation. Using Newton’s laws of physics, we can model the motion of the planets in the Solar System quite accurately. However, in the early 1970s, scientists discovered that this did not work for disk galaxies – the stars at their outer edges, away from the gravitational force of all matter at their centres – moving much faster than Newton’s theory predicted. As a result, physicists proposed that an invisible substance called “dark matter” exerted an extra gravitational pull, causing the stars to accelerate – a theory that became widely accepted. However, in a recent review, my colleagues and I suggested that observations at multiple scales are much better explained in an alternative theory o...
