labnet writes: Millions of people across Australia have been affected by major outages across multiple businesses, affecting banks, airlines and media outlets.

Around 3pm on Friday, computers across the country began shutting down with multiple workers reporting issues at multiple different businesses.

The issue comes from a "bluescreen error" which is a result of a Crowdstrike outage, with servers and devices getting stuck in "boot loops".

Multiple media organisations reported issues with networks, including the ABC, SBS, Channel 7, Channel 9 and News Corp Australia.

Submission + - Australian Scientists Just Worked Out How Zinc-Air Batteries Can Replace Lithium (gizmodo.com.au)

These new catalysts are produced through the simultaneous control of the composition, size and crystallinity of metal oxides of earth-abundant elements like iron, cobalt and nickel. They can then be applied to build rechargeable zinc-air batteries.

Researcher Dr Li Wei, also from the University's Faculty of Engineering and Information Technologies, said trials of zinc-air batteries developed with the new catalysts had demonstrated "excellent rechargeability" – including less than a 10 percent battery efficacy drop over 60 discharging/charging cycles of 120 hours.

Submission + - Single ion clock 100 times more accurate than atomic clock (news.com.au)

University of New South Wales School of Physics professor Victor Flambaum has found a method of timekeeping nearly 100 times more accurate than the best atomic clocks. By using the orbit of a neutron around an atomic nucleus he says the system stays accurate to within 1/20th of a second over billions of years. Although perhaps not for daily use, the technology could prove valuable in science experiments where chronological accuracy is paramount, Prof Flambaum said.
