From 29 August 2013 to 27 January 2014, Melbourne Museum hosted Inside: Life in Children's Homes and Institutions. This travelling exhibition was developed by the National Museum of Australia in the wake of the Australian Government's 2009 national apology to Forgotten Australians and Former Child Migrants.

Some half a million children spent time in institutional care during the 20th century and while some feel that they were treated well, others experienced terrible suffering, neglect, and in the worst cases, abuse. This exhibition is presented through personal accounts of people who grew up in care. Sometimes harrowing, often distressing, Inside's purpose is to acknowledge stories that have long been suppressed or ignored.

An area of the exhibition was set aside with slips of paper and an invitation to visitors to record their reflections. Hundreds of visitors filled out a slip of paper and pinned it up, compiling a very intimate account of how they felt about the exhibition. Many of the comments are extremely personal and we thank visitors for sharing their experiences in such an open and honest way.

The excerpts and examples in this post show the range of responses from former residents of Children's Homes, their friends and families, and from people who had no previous connection to this awful part of our country's history.

My father lived in foster care. I still remember the stories of how he was beaten. It's so painful looking at these things. Caterina,19
1930s-1950s St Augustine's Geelong was my father's home from 5 weeks old. Messed him up for life, but he managed to be a wonderful husband, father and mate. Darren, 49
So sad, so ANGRY. Such abuse shapes your life and requires great courage, support and time to work through. Monique, 34
For my Grandfather, placed in the Ballarat Orphanage at age 3 in 1923. We never heard your full story as you didn't want to talk about it. This exhibition has given us an idea of what your life would have been like. May you rest in peace. xx Shaye, 37
Keep the truth shining and justice for all, I was 12 year old when I was put into a home for no reason at all like many girls. I will hold my head up / no shame. Suzanne, 45

The homes are still with us today, happy for the ones who have been able to move on. Heather, 70
It was tough there but I turned out all right. Don, 74
I was seven when I was told I had nine other brothers and sisters and I had my first birthday party when I turned 17. Alf, 62
This is an authentic exhibition that reveals a very dark side of Australia's 20th century social history. The personal stories of abuse make me weak. But I do not perceive the story told to be wholly balanced. Mark Scott (MD of the ABC) was a child migrant and internee at Fairbridge, NSW. A few resilient souls did rise above the indifferent care at orphanages and achieved success. Tell that story too please. David, 59
It was foster care for me… 10 long years of moving from house to house. At Christmas time three houses in one week. The memories of a gift bring tears to my eyes. A simple Beatles poster from strangers. These people had taken time to find out what I liked – meant the world to me. Never abused but never loved, roof over my head but not a home, always alone but for the memory of that Beatles poster. That memory brings me warmth. That Christmas I was known. Juliette, 36
I am so sorry for ever saying 'it's in the past, get over it,' 'I didn't do it, why should I pay!’ - I now understand my ignorance to these horrific occurrences. My compassion is at large thanks to this display. Anon age 18

Alpine frogs and chytrid fungus

Frogs were an important focus for the Alps Bioscan survey in Victoria's Alpine National Park in November last year. The deadly amphibian chytrid fungus, Batrachochytrium dendrobatidis, thrives in cool environments, meaning high-altitude frog populations are particularly susceptible.

Dr Katie Smith, Collection Manager of Vertebrates, led the frog-hunting team at the Alps and explained why this fungus is so insidious. "It's a major contributor to global amphibian decline. Lots of frogs worldwide are affected," she said. "It penetrates their skin and leads to death in some species and individuals, while some are able to survive it and act as carriers."

The museum's frog team searched for frogs in several sites in the Alps and collected skin swabs from every frog found. The swabs will be tested for the presence of chytrid (pronounced 'kit-trid') as part of ongoing monitoring by researchers from the Arthur Rylah Institute for Environmental Research. "We need to know what populations have it and whether this leads to changes in those populations, such as whether there's lower species diversity in areas where chytrid fungus is present."

The chytrid fungus has a free-living stage called a zoospore and a reproductive stage called a zoosporangium. Zoospores can live several weeks in the water until they find a host frog to infect. Once settled, the zoosporangia cause the frog's skin to thicken and slough away. There are a few hypotheses as to how the chytrid fungus kills frogs. One hypothesis proposes that a frog with a heavy chytrid infestation can't maintain its salt balance. Sodium and potassium levels, essential for normal muscle and nerve function, drop significantly and the frog dies from cardiac arrest.

Researchers believe that the fungus arrived in Australia in the 1970s, and is linked to the sudden decline (and in some cases, extinction,) of several local species, including the Southern Gastric Brooding Frog and the Southern Corroborree Frog. There are a few theories about how it got here, but the most likely culprit is the international trade in African Clawed Frogs for use in pregnancy tests. In the 1930s it was discovered that injecting one of these frogs with the urine of a pregnant woman caused the animal to produce eggs. Hundreds of thousands of frogs were brought into Australia from Africa for this purpose and probably, with them, the chytrid fungus. While the fungus was first identified in 1998, retrospective examination of historical specimens found the earliest known chytrid infestation on an animal collected in 1938. This African Clawed Frog specimen, held by the South African Museum, supports the theory of African origin.

Once loose in a new environment, chytrid fungus can spread rapidly. "It can be spread by frogs – anything that moves through those water bodies, even other animals that visit those areas and researchers themselves," explained Katie. "You might walk into one site, jump in the car and accidentally transfer it to a healthy population."

You can help prevent the spread of chytrid fungus in a couple of ways. Firstly, says Katie, "never move a frog, tadpoles or eggs that you find in one area to another area, because you don't know which populations may have the chytrid fungus." Frogs are protected in Australia which means that you cannot legally catch, remove or relocate them; the threat of chytrid fungus is another good reason to leave them where they are. Frogs often hitchhike from Queensland in bunches of bananas, so if you find a stowaway in your supermarket, follow the instructions of the Victorian Frog Group and never release the frog into the wild.

Katie continued, "secondly, if you're moving between water bodies, wash your shoes really well and anything else you put in water." The Alps Bioscan teams bleached and scrubbed shoes and equipment between each aquatic field site, and Katie's frog team wore fresh surgical gloves when handling each frog.

The results from the survey and chytrid tests will be available later this year once the researchers have completed their analysis.

This January we have The Brickman in residence at Melbourne Museum! Ryan McNaught is LEGO® Certified Professional - and yes, that means his job is to play with LEGO®.

Ryan created two mystery mosaics for our visitors to construct over the summer holidays. Thousands of coloured plastic bricks, plus the support rig that holds the mosaics, arrived just before Christmas and the fun began on Boxing Day.

Great White Sharks at IMAX

William Winram is a champion freediver and a passionate advocate for the protection of marine ecosystems. He uses his freediving abilities to help monitor shark populations, and he visited Melbourne Museum recently to talk about Great White Shark 3D, a new IMAX film that features him doing exactly that.

Most divers use SCUBA breathing apparatus, but freedivers like William reach similar depths while holding their breath. This is a very different way to interact with sharks, as William explains. "When you hold your breath, your heart rate reflexively slows. There's a whole shift, physiologically, that doesn't happen in SCUBA diving." He believes that freediving makes him less intrusive, because "with SCUBA, you're entering as an alien. You're taking apparatus from the surface world, so right away your relationship is totally different." Freedivers can also move more freely in the water column, and don't generate noisy bubbles. "For a lot of species, bubbles are a sign of aggression," says William.  "If a male sea lion is getting upset, he blows bubbles and barks at us. That's how he shows his dissatisfaction."

William describes the sharks he encounters – Great White Sharks, Hammerheads, Tiger Sharks and others – as "shy, curious and cautious predators", quite unlike the killing machines of media and cinema. "Sharks are not obsessed with or addicted to killing, but they do need to eat. They know that we're not their normal diet, so they don't typically eat us." His calm, respectful approach to the world's largest predatory fishes means he is able to tag sharks harmlessly, unlike some other tagging techniques that often kill the animal.

"It's like you're walking down the hallway and I hit you in the rear end with a hypodermic needle. Afterwards you have a little bruise but you're fine." He and his colleagues aim for the thick muscle at the base of the shark's dorsal fin and use a specially modified spearfishing gun. All that's left is a small dart and tag – and these tags are allowing scientists to learn about the feeding behaviour and global movement of sharks. Tagging has also shown that Great White Sharks head for a mysterious area in the middle of the Pacific known as the Shark Café. No one is quite sure what the sharks do there, but it is clear that the animals have complex annual migratory patterns.

He sees Great White 3D as an opportunity to address the misunderstandings about sharks and encourage interest in their conservation. "We like to demonise sharks and we like to glorify other creatures, and all of it is false. People want to have this fantasy, an unreal world where things are either beautiful or ugly, nice or not. Sharks are easy to exploit because they're not cute and cuddly," he says.

Like all apex predators, Great White Sharks are found in relatively low numbers, yet they are vital in moderating populations of other species. Ecosystems suffer when they lose their apex predators, so the decline in sharks from human activities worries William very much. "We need to understand that we are part of an ecosystem. 50 per cent of the oxygen that we breathe comes from the sea.  At a certain point, if you kill them all off, the sea is done. It's time to respect your position and your role in your ecosystem."

Great White Shark 3D is now playing at IMAX Melbourne Museum.

Burrowing bees

No biologist worth their salt will stumble across a burrow in the ground without having a good stickybeak. And museum biologists are definitely worth their salt*.

So when the Alpine National Park Bioscan team found several hundred small burrows in one spot, they couldn't just wonder if they were made by crayfish or perhaps mole crickets. This hypothesis needed testing. Colin from Live Exhibits got to digging.

He stuck a blade of grass down the burrow and used a spoon to carefully dig around it. About 30 or 40 cm down he found, not a cray or cricket, but a little bee. It was no coincidence; a second excavation turned up another bee in the next burrow.

The bees belong to the subfamily Halictinae, which happens to be the speciality of museum entomologist and bioscan participant Dr Ken Walker. He collects most of his study specimens as they are out foraging and rarely sees the burrows. And he'd never seen burrows in such high density –about 400 in one small grassy area.

Ken explained that the bees belonging to the genus Lasioglossum and subgenus Parasphecodes. "Lasioglossum is one of the largest genera in Australia, doing most of the work of pollinating." These burrows are where the female bees brood the next generation.

"They're a semi-social bee," said Ken. "In a single nest there can be six to ten females, which are all queens. They all lay their own eggs, and they all help excavate that main tunnel but each one of them then makes a lateral tunnel by themselves. At the end they build a group of cells each lined with saliva, and they put in a pollen ball mixed with a little bit of nectar, and they lay an egg and close the whole thing up."

But that's not the end of the story, because the bee larva isn't alone in the cell. Looking closely, Ken spotted a number of large mites on the backs of the bees. The mites are harmless to the bee since they're a non-feeding, migratory (or hypopial) life stage, waiting patiently for the bee to finish stocking the brood cell with pollen.

Said Ken, "just before the bee closes up the cell, she turns around and brushes one or two mites off, which then develop to the feeding and sexual stages." The mites act like little housekeepers, eating any mould or fungus that attacks the pollen ball and thus keeping it fresh for the developing bee. When the new adult bee is ready to emerge, the mites' own young clamber aboard and travel on to the next burrow. "It's a wonderful relationship there."

So there you have it – nosy biologists reveal an underground community of fascinating little animals, and Parks Victoria rangers have an interesting reason to recommend that tents be pitched away from the field of muddy burrows.

*Humans contain about 0.4% salt by weight. So a 70kg museum biologist, say, contains about 280g salt**. That much table salt costs about a dollar from a supermarket. If instead we say they're worth their weight in gold, according to today's price, and the Dynamic Earth scale, that puts our 70kg biologist at $3,112,900. The real value is probably somewhere in the middle.

**Except marine biologists. They're a bit saltier.

We're sorry to hear of the recent death of Sydney artist Martin Sharp, His many achievements – among them the co-creation of Oz magazine in the late 1960s and the psychedelic refurbishment of Sydney's Luna Park in the 1970s – Sharp designed the tenth and final panel of the Federation Tapestry which hangs in Melbourne Museum.

Central to Sharp's tapestry, titled Celebrations 2001, is one of his most often-used motifs: the word 'Eternity' in elegant copperplate script. This is a tribute to Arthur Stace who wrote the word on the streets of Sydney, anonymously, for decades. Sharp surrounded this centrepiece with other powerful images of Australia: 'Sorry' written in the sky above the Sydney Opera House, an artwork by Ginger Riley, a quote from Patrick White, and the First Fleet.
