How Alone Australia can help us understand and appreciate our place in nature

More than a million Australians have tuned in to Alone Australia, SBS’s highest-rating series for 2023 to date.

Key Points: 
  • More than a million Australians have tuned in to Alone Australia, SBS’s highest-rating series for 2023 to date.
  • And what can it tell us about our own relationships with nature?
  • As armchair experts watching from home, we may reflect on how we would act if we had to survive alone in a remote place.

Nature is everywhere

    • Watching Alone Australia may generate the sense that nature, and nature experiences, happen “out there” away from urban places and other people.
    • This narrative has been fuelled by media, including David Attenborough’s awe-inspiring nature documentaries, which paint nature and humans as separate.
    • While this kind of media can inspire fascination with nature, it can be damaging if it perpetuates an idea that humans are separate from nature.

We shape nature, and nature shapes us

    • The show helps us widen our view of valuing nature from what it provides for us (instrumental/utilitarian values) to seeing beauty and worth in nature itself (intrinsic values).
    • Previous overseas seasons of Alone have highlighted utilitarian nature relationships, with most contestants being white male survivalists.
    • Experiences in nature early in life shape these relationships.
    • Meaningful nature experiences can include looking after nature (gardening, indoor plants), bushwalks, visiting botanical gardens, or getting up close and personal with wildlife at your local zoo.

Nature as medicine

    • This will be apparent to many of us who sought solace in nature during COVID lockdowns.
    • Connecting with nature, including in urban places, can help people feel less lonely and support their wellbeing in many ways.
    • It’s about oneness with nature, but sharing it collectively – kindness, actions towards others, not being alone out there.

Learning about nature

    • TV nature content like Alone Australia is educational.
    • Indeed, recent renewed interest in urban foraging has been touted as cementing our connections to place and sense of belonging.

We need nature, and nature needs us

    • Ultimately, everything we need for survival, including clean water, shelter and food, is derived from nature, even when we live in a city.
    • The “successes” of the contestants are determined by their ability to understand their relationship to the land and how to meet their basic survival needs.
    • If we broaden our view of nature and see ourselves as interwoven in nature’s rich tapestry, as many of the contestants do, we can gain more than basic survival.
    • If TV nature content such as Alone Australia encourages us to reflect on our relationship with nature and seek meaningful moments with nature and nature knowledge, then perhaps it might lead us to strengthen our environmental identities and act as nature stewards.

People are complaining about Mercury in retrograde. But what does it actually mean?

So it seems a bit rough that we blame Mercury for all our problems three to four times a year when it’s in retrograde.

Key Points: 
  • So it seems a bit rough that we blame Mercury for all our problems three to four times a year when it’s in retrograde.
  • But what does it mean when we say Mercury is “in retrograde”?
  • A matter of orbits
    Retrograde motion means a planet is moving in the opposite direction to normal around the Sun.
  • Because Mercury is closest to the Sun and has the fastest orbit, it appears to move backwards in the sky more often than any other planet.

Sex and the single gene: new research shows a genetic ‘master switch’ determines sex in most animals

Retrieved on: 
Wednesday, April 19, 2023

In humans and other animals, sex is usually determined by a single gene.

Key Points: 
  • In humans and other animals, sex is usually determined by a single gene.
  • We conclude that sex is normally determined by a single gene.

The human ‘master switch’ for sex

    • Females make eggs, which carry a single X chromosome, while males make sperm, half carrying an X and half carrying a Y.
    • Random fusion of eggs and sperm delivers half XX females and half XY males, for a 1:1 sex ratio.

Sex in other vertebrates

    • Among animals with backbones (vertebrates), there is a huge variety of systems that determine sex.
    • Some vertebrates have the opposite – a female-dominant gene on the X chromosome.
    • If the ratio favours one sex, individuals that produce more of the other sex will leave more descendants and their genes will spread until a 1:1 ratio is achieved.

Some exceptional species

    • Then there are species with two or more pairs of sex chromosomes.
    • And what about species, like the African clawed toad, which have two copies of their whole genome, so should have two pairs of sex chromosomes and sex genes?
    • So there are lots of exceptional species that seem to have multiple sex chromosomes and sex genes in defiance of the expectation that only a single sex gene can produce a stable system.

Polygenic sex – is there any such thing?

    • In our recent paper we examine classic examples and recent claims for polygenic sex determination.
    • Multiple sex chromosomes need not mean multiple sex genes.
    • A Japanese frog has different sex chromosomes on different islands, but they are all variants of the same chromosome.
    • Strains bred independently in laboratories for 30 or 40 years have aberrant sex ratios and multiple sex genes.

Winning the war of the sex genes

    • Their problem is incompatibility of different sex chromosomes and sex genes.
    • If an XY male mates with a ZW female, offspring have all sorts of combinations of sex genes.
    • Species hybrids may reveal many genes with major and minor effects on sex determination.

From platypus to parsecs and milliCrab: why do astronomers use such weird units?

Retrieved on: 
Tuesday, April 18, 2023

These outlandish comparisons are the invention of Jerusalem Post journalist Aaron Reich (who bills himself as “creator of the giraffe metric”), but real astronomers sometimes measure celestial objects with units that are just as strange.

Key Points: 
  • These outlandish comparisons are the invention of Jerusalem Post journalist Aaron Reich (who bills himself as “creator of the giraffe metric”), but real astronomers sometimes measure celestial objects with units that are just as strange.
  • The idea of a planet that’s 85% the mass of Earth seems straightforward.

Why do astronomers use such strange units?

    • Earth’s radius is about 638 million cm, or 7.5 million Astros.
    • That number of Astros is a bit ridiculous, which is why we adjust our unit choice to one that makes more sense.
    • At an even larger scale, consider the star Betelguese: its radius is 83,000 Earths, or 764 times the radius of the Sun.

Heavy stuff

    • If we want to measure how heavy an asteroid is, we could do it with camels – but in space we’re more interested in mass than in weight.
    • Mass is a measure of how much stuff something is made of.
    • On the other hand, Astro’s mass is how much stuff he’s made of – and it’s the same no matter which planet he’s on.

Astronomical units and parsecs

    • The Sun and Earth are 149 million kilometres apart, and we give this distance a name: an astronomical unit (AU).
    • For example, the centre of our very own galaxy, the Milky Way, is about 8,000 parsecs away from Earth, or 1.6 million AU.

Magnitudes

    • In the second century BC, the ancient Greek astronomer Hipparchus looked up at space and gave the brightest stars a value of 1 and the faintest stars a value of 6.
    • Even more confusing than a negative brightness, each single step in magnitude is a 2.512 times difference in brightness.
    • The star Vega has an apparent magnitude of 0, which is two and a bit times brighter than the star Antares with an apparent magnitude of 1.

At last, the milliCrab

    • The light we use to take pictures of your bones is called X-ray light.
    • When astronomers use X-ray light to observe the sky we sometimes measure brightness in “Crabs”.
    • It’s so bright in X-ray light that astronomers have been using it to calibrate their telescopes since the 1970s.
