Real problem, wrong solution: why the Nationals shouldn’t politicise the science replication crisis

Across science, only around half of published results can be successfully replicated. But while this is a serious problem, the proposed public audit looks like a political bid to cast doubt on science.

We can make roof tiles with built-in solar cells – now the challenge is to make them cheaper

Australia is in the midst of a solar energy boom, yet it is lagging behind other countries when it comes to ‘building-integrated photovoltaics’ - solar cells built into the very fabric of buildings.

Curious Kids: How big is the International Space Station?

The International Space Station is the biggest human made structure in space and the third brightest object in the sky. But the living conditions for the six astronauts on it are quite cramped.

Apple Arcade and Google Stadia aim to offer frictionless gaming, if your NBN plan can handle it

Google’s Stadia and Apple Arcade will rattle the gaming world this year. Both aim to solve current limitations, but as user experience improves, issues around connectivity and cost arise.
Very rarely, depending on where you are in the world, your compass can actually point to true north. https://www.shutterstock.com

Explainer: what happens when magnetic north and true north align?

Recently, magnetic compasses at Greenwich pointed directly at true north for the first time in 360 years. This is currently happening in Western Australia too. But what does it mean?
The giant freshwater prawn is native to the Indo-West Pacific from northwest India to Vietnam, Philippines, New Guinea and northern Australia. It has been introduced into many countries for aquaculture. https://www.shutterstock.com

Breeding single-sex animal populations could help prevent disease and poverty

Entire populations of prawn ‘super-females’ are now being commercially distributed. The science behind this continues to advance and could have a far-reaching impact on both humans and animals.
The universe is home to a dizzying number of stars and planets. But the vast bulk of the universe is thought to be invisible dark matter. Illustris Collaboration

Why do astronomers believe in dark matter?

Why do astronomers believe there’s dark matter when it cannot be directly detected? Let’s look at the evidence, and see what dark matter’s presence means for our universe.

India’s moon mission should be considered a success, and a lesson in spacefaring

Despite a last-minute crash-landing, efforts behind India’s moon mission should be applauded. The endeavor has set an example for emerging space programs across the globe.
Galileo thought Saturn looked a bit like the head of a teddy bear with two big ears. He thought it may be made of three planets. www.shuttershock.com

Curious Kids: why does Saturn have rings?

Most people think that many millions of years ago, Saturn didn’t have rings at all. Instead, it had a big moon moving around it. Eventually, the moon burst and broke into pieces.
More than 200 gene variants have been linked to outstanding sporting performance and this number could increase as we continue to research the link between genetics and athlete performance. Lukas Coch/AAP

Will the genetic screening of athletes change sport as we know it?

Genetic testing could help us build targeted and effective training routines for athletes, but the emerging science could also introduce opportunity for discrimination in the sporting world.

Timely intervention: how Doctor Who shapes public attitudes to science

The first peer-reviewed survey of Doctor Who fans’ attitudes to science reveals it was literally life-changing TV for some. But the verdicts were surprisingly nuanced and sometimes contradictory.
