Military and SES personnel being taught analog communication and navigation techniques as experts warn solar flare could knock out ‘critical space infrastructure’

Australia’s emergency services and military personnel are being trained to read paper maps, navigate without GPS support and sail by the stars in case something knocks out the nation’s space capabilities.

A panel at the 19th Australian Space Forum in Adelaide on Wednesday was asked to consider what would happen “if we suddenly lost access to critical space infrastructure – no satellites, no GPS, no remote sensing, no secure communications?”

Exclusive: Research spanning 82 countries finds antibiotic resistance increased in every region between 2004 and 2022

Harry Booth has had a rough run through Australia’s coldest months. The 13-year-old has been in and out of hospital with a range of common chest and urinary tract infections that his doctors find challenging to treat.

Harry was born with kidney failure and began dialysis at six months old, before receiving a kidney transplant from his father at age four. The surgery saved his life but comes with a trade-off: he now needs to take medications that suppress his immune system to prevent his body from rejecting the kidney.

AI could help win ‘race against extinction’ of vital plants, say botanists

Posted on by

Tech is helping to identify and save new specimens and could open ‘genomic goldmine’ of fungi data

The rise of AI and digitisation could be a turning point in the “race against extinction” faced by botanists trying to identify and save vital plants before they vanish, according to a major report from Royal Botanic Gardens, Kew.

New technology is enabling scientists to track how flowering times have shifted by weeks around the world, rapidly identify new specimens and even get crucial genetic data from 180-year-old fungus specimens, potentially opening a “genomic goldmine”. Digitisation and online access to millions of specimens that were until now only accessible in archives is also producing new insights, especially in the global south.

Geochronologists say Antrim coastline’s basalt columns developed over 5.5m years – 8m less than thought

For centuries, the tale has been passed from generation to generation: how the Irish giant Finn McCool built the Giant’s Causeway in Northern Ireland to fight Benandonner, his Scottish rival, by hurling chunks of the Antrim coastline into the sea.

Now, scientists have revealed it was intense volcanic activity during a “major globally impacting volcanic event” – and not a legendary battle between two destructive giants – that led to the formation of the coastline’s 40,000 distinctive interlocking basalt columns about 60m years ago.
