The national festival that reaches nearly 2 million people through thousands of events is back from 12 to 20 August.

Entertainment, business, environment, food and wine, Indigenous media, the arts, health, technology, farming and agriculture, lifestyle, education, LGBTQI+, and disability media…National Science Week offers stories for every round.

Here are a few early picks:

Koo-koo-kaa-kaa, crawk, howl… nationwide project to proclaim Australia’s favourite call of the wild.

Media contacts: Laura Boland, laura@scienceinpublic.com.au or 0408 166 426; or Tanya Ha, tanya@scienceinpublic.com.au or 0404 083 863.

Participate at: www.abc.net.au/sounds from 31 July.

Do you love the summer night sounds of cicadas? Or the outback howl of dingoes? Are you intrigued by the lyrebird’s mimicry or the mating croaks of frisky frogs?

The search is on to find our most-loved Aussie animal sound. This National Science Week, ABC Science wants people to go online to eavesdrop on the animal kingdom, explore the wonder and science of bioacoustics, and vote for their favourite call of the wild.

“Bioacoustics – the study of the sounds of wildlife – is really important for science,” says ecologist and science communicator Dr Jen Martin.

Thursday at the Genetics Congress

• Are bin chickens spreading Japanese encephalitis? Anjana Karawita from CSIRO says the native ibis could be implicated in the spread.
• Platypus viability threatened by dams, genetic analysis reveals. Luis Mijangos, Bill Sherwin, and colleagues from UNSW show how dams are separating our platypus populations.
• Bilby scats, DNA and Indigenous kids: Carolyn Hogg from University of Sydney has designed a scat-based test to assess the health of endangered bilby populations.
• Victorian koalas are more isolated, according to University of Sydney researchers, as bushfires take their toll.
• What got into your dog? Lucas Huggins has devised a portable test to detect a wide range of parasite infections simultaneously.
• What are the causes and consequences of sex reversal in fish? Unexpected impacts of a warming world.

mRNA ‘quality control’ pioneers Allan Jacobson and Lynne Maquat receive US$500,000 Gruber Genetics Prize in Melbourne

Every plant, every animal, every human depends on mRNA to accurately translate the DNA of their genetic code into proteins, the building blocks of life.

Are bin chickens spreading deadly diseases? Anjana Karawita and his colleagues at CSIRO’s Australian Centre for Disease Preparedness in Geelong are investigating the role of Australian ibis in spreading Japanese encephalitis virus

By 2100, the impacts of sea level rise and storm surge are predicted to result in a $442 billion economic loss according to a study led by the University of Melbourne and commissioned by the Victorian Marine & Coastal Council and Life Saving Victoria.

• Impacts on land and property along the Victorian coast are predicted to reach a loss of $337 billion, with a further loss of up to $105 billion for wetlands.
• More than 80,000 existing residential, commercial, and industrial properties covering 45,000 hectares will be impacted.
• 144,000 hectares of coastal reserves will be affected as will 288,000 hectares of Victoria’s wetlands.
• The cumulative impact will be about $40 billion by 2040. Without action, it will grow ten times as 2100 approaches.
• Appropriate action over the next decade will dramatically reduce the long-term costs.

71 per cent of Australians believe that gene testing does not necessarily contribute to effective cancer or disease treatment according to a survey by Lonergan on behalf of gene technology company, Illumina.

Life’s tough for African killifish. They only live for three to four months. They suffer from the same diseases of old-aging that we do – cancer, short telomeres, and wasting muscles. But in their old age the muscle wasting slows and may even reverse. Could that happen to people as well? Avnika Ruparelia is unraveling the mysteries of vertebrate aging at Australia’s only killifish research facility.

• New gene linked to persistent stuttering, thanks to Michael Hildebrand’s team across 18 institutions. Brain imaging shows that people with this defective gene develop anomalies in brain regions critical for speech.
• Early and personalised interventions into cerebral palsy are possible from broad genomic testing, says Clare van Eyk from Robinson Research Institute.
• Killifish suffer from the same diseases of old-aging that we do – cancer, short telomeres, and wasting muscles. Then the muscle wasting slows and may even reverse. Could that happen to people as well? Avnika Ruparelia unravels the mysteries of vertebrate aging at Australia’s only killifish research facility.
• Faster, kinder, less expensive: using genomic sequencing to diagnose mitochondrial disorders has many benefits says MCRI’s John Christodoulou.
• Cold cases: around 70% of patients with suspected genetic disorders don’t get a diagnosis from their genomic testing. Fiona Lynch from MCRI is exploring if reanalysis years later could solve these cold cases.
• 71 per cent of Australians believe that gene testing does not necessarily contribute to effective cancer or disease treatment, according to a survey released by Illumina. At the same time lives are being transformed, for those in the know.
