Frontotemporal dementia: we discovered a brain fold that may delay onset of symptoms

Retrieved on: 
Tuesday, November 7, 2023

Frontotemporal dementia is a rare disease – thought to account for only one in every 20 cases of dementia.

Key Points: 
  • Frontotemporal dementia is a rare disease – thought to account for only one in every 20 cases of dementia.
  • People diagnosed with frontotemporal dementia usually die within eight years of their diagnosis.
  • We discovered that the way your brain looks may determine your resilience to the condition.

Brain folds

  • During pregnancy, as a foetus’s brain grows within the womb, it develops its distinctive folds while expanding within the skull.
  • These brain folds play an important role in our later cognitive function.
  • The folds that form early in foetal development are found in both sides of the brain in every person.
  • Our team studied MRI brain images of 186 people who had been diagnosed with frontotemporal dementia.
  • Around 57% of participants had a paracingulate sulcus on the right side of their brain.
  • We discovered that in participants who had this extra fold on the right side of their brain, their dementia symptoms began on average two and a half years later.

Cognitive reserve

  • Brain reserve describes a structure in the brain which provides resilience to a disease before symptoms develop.
  • After this critical point, people with high brain reserve decline rapidly – faster than people with low brain reserve.
  • For example, high brain reserve explains why Alzheimer’s disease starts later in highly educated people – though the disease progresses faster for them when symptoms start.

How apps and influencers are changing the way we sleep, for better or for worse

This is the final article in The Conversation’s six-part series on insomnia, which charts the rise of insomnia during industrialisation to sleep apps today.

Key Points: 
  • This is the final article in The Conversation’s six-part series on insomnia, which charts the rise of insomnia during industrialisation to sleep apps today.
  • Insomnia is not just a personal issue that affects an individual’s health and wellbeing.
  • The global insomnia market is expected to reach US$6.3 billion by 2030, driven by increased diagnoses and therapy, as well as sleep aids, including sleep apps.

There’s an app for that

  • You can buy wearable devices, such as smartwatches and smart rings or wristbands, to digitally monitor your sleep.
  • You can download apps that record how long you sleep and where you can log your tiredness and concentration levels.
  • You can also buy “smart” pillows, mattresses and a range of smart light-fittings and lightbulbs to help track and improve sleep.
  • You can listen to “sleep stories” – bedtime stories, music or guided meditations meant to help you sleep.

Sharing and connecting can help

  • Sharing and connection can ease the loneliness we know can impact sleep.
  • So online sharing, support and feelings of belonging can alleviate the stresses and unhappiness that may prevent people from finding a good night’s sleep.

What is this fixation costing us?

  • A focus on sleep can create a vicious cycle in which worrying about a lack of sleep can itself worsen sleep.
  • Using sleep-tracking apps and wearable devices can encourage people to become overly fixated on the metrics these technologies gather.
  • The data generated by digital devices are not necessarily accurate or useful, particularly for groups such as older people.

Are we missing the bigger issue?

  • People living in poor housing or in noisy environments have little choice over the conditions in which they seek good sleep.
  • And multiple socioeconomic factors (for instance, gender, ethnicity and economic hardship) can combine, making it even more likely to have poor sleep.
  • Yet, much of the advice offered to people about how to improve their sleep focuses on individual responsibility to make changes.
  • It assumes everyone can buy the latest technologies or can change their environment or lifestyle to find better “sleep health”.

The new context of their lives means the clothes they wore for the city no longer work for their new lives.

Key Points: 
  • The new context of their lives means the clothes they wore for the city no longer work for their new lives.
  • This is also true in the climate crisis.
  • Australia’s carbon footprint from the consumption and use of fashion is the world’s biggest, a dubious distinction in a materialistic world.

Lessons from wartime

  • To conserve precious resources, shorter skirts, minimal detailing and a focus on utility became the norm.
  • People adapted their personal aesthetics and appearance because the situation was grave and they wanted to “do their bit” to help with the war effort.
  • This wartime response reflected the priorities and values of society as a whole as well as most people in that society.

So what can we do today?

  • That makes Australians the second highest textiles consumers in the world after the USA , and is 60% more than we bought even 15 years ago.
  • If we buy ten to 12 new items a year, we can replace our entire wardrobe in about seven years.
  • Read more:
    Secondhand clothing sales are booming – and may help solve the sustainability crisis in the fashion industry

Choosing clothes to fit our values

  • In the case of clothing, we should evaluate our choices in relation to the values we hold.
  • Clothes need to reflect a person’s situation as well as their identity to “work” well.
  • We may start to look different, but that change signifies our values in action.

Domicide: the destruction of homes in Gaza reminds me of what happened to my city, Homs

Retrieved on: 
Friday, October 27, 2023

The Israeli bombardment of Gaza following the Hamas attack on southern Israel on October 7 has forced hundreds of thousands of Palestinians out of their homes.

Key Points: 
  • The Israeli bombardment of Gaza following the Hamas attack on southern Israel on October 7 has forced hundreds of thousands of Palestinians out of their homes.
  • At least 43% of all housing units in the Gaza Strip have been either destroyed or damaged since the start of the hostilities, according to the Ministry of Public Works and Housing in Gaza.
  • Israel says that 1,400 people were killed in the Hamas attack on Israel and more than 220 taken hostage.
  • Domicide refers to the deliberate destruction of home, or the killing of the city or home.

The destruction of Homs

  • My home city of Homs, Syria, which I focus on in my research, has been completely transformed since the 2011 uprising against the government of Bashar al Assad.
  • Over 50% of the neighbourhoods have been heavily destroyed, and over a quarter partially destroyed.
  • In Homs, for example, whole neighbourhoods that opposed the Assad regime were targeted and razed to the ground.

Domicide in Gaza

  • There is no need to compare Homs and Gaza, as each place has its own context and struggle.
  • Gaza has been described as an open prison and people in that open prison have been pushed away from their homes.
  • Raz Segal, an Israeli historian, wrote: “Israel’s genocidal assault on Gaza is quite explicit, open, and unashamed.” Others argue vehemently against any moral equivalence with the Hamas attacks.

Catastrophe for Palestinians

  • It’s not the first time that Palestinians in Gaza have had their homes destroyed.
  • Many of the Palestinians who live in Gaza are people who have been displaced before.
  • This is why many academics, activists, journalists and even Queen Rania Al Abdullah of Jordan, call for context, for situating the Palestinian struggle within a history of suffering, dispossession and forced displacement since the Nakba (catastrophe) in 1948.

Ping-pong diplomacy: Australian table tennis players return to China, five decades after historic tour

Retrieved on: 
Friday, October 27, 2023

Only weeks after the team’s headline-making tour, Australia’s then opposition leader, Gough Whitlam, led a delegation to Beijing promising to open diplomatic relations “when elected”.

Key Points: 
  • Only weeks after the team’s headline-making tour, Australia’s then opposition leader, Gough Whitlam, led a delegation to Beijing promising to open diplomatic relations “when elected”.
  • One was table tennis, one was basketball and one was volleyball.
  • One was table tennis, one was basketball and one was volleyball.

‘A crowd of 8,000 people’

  • A revolutionary who became one of China’s most revered statesmen, he advocated peaceful co-existence with the West and other nations.
  • The American team embarked on their tour first – setting the stage for then-President Richard Nixon’s famous visit to Beijing in 1972.
  • Paul Pinkewich had just turned 20 at the time of the visit, teammate Steve Knapp was only 18.
  • Our first match in Canton, now Guangzhou, I think it was a crowd of 8,000 people,” he recalls.
  • “Do you wear this hair because of your disagreement with society or because it is a style?” Knapp replied, “It is the fashion.”
  • “Can you believe, one table in the middle of the Capital Stadium [in Beijing] with 18,000 spectators, and that was just an amazing experience.
  • But they always let the woman win.” That woman was Anne Middleton, the other player on the 1971 tour, who has since passed away.
  • After the trip we were labelled as communists […] but we were interested in friendship first, competition second.”

Why sport diplomacy matters

  • Beijing has continued to use sport as a diplomatic tool, including becoming the first city in the world to host both a summer and winter Olympic Games (Beijing in 2008 and 2022).
  • French educator Baron Pierre de Coubertin founded the International Olympic Committee in 1894, believing Olympics were a global event.
  • A new term has also emerged in recent years – almost always applied by researchers in democratic nations – to describe undemocratic nations’ forays into global sport: sportswashing.
  • “Amity between people holds the key to sound relations between countries.” At the heart of such amity, sport continues to play a significant role.

We quizzed 4,000 people on the economy – here's who knew the most

Retrieved on: 
Thursday, October 26, 2023

My colleagues, Dan Kenealy and Hayley Bennett, and I used a survey to study public attitudes and knowledge about the UK economy and politics.

Key Points: 
  • My colleagues, Dan Kenealy and Hayley Bennett, and I used a survey to study public attitudes and knowledge about the UK economy and politics.
  • We analysed the responses of more than 4,400 adults, and found that many people answer fact-based questions about the economy, employment rights and benefits incorrectly.
  • For example, only just under half knew that stock markets can rise even when the economy is not growing.

Welfare and benefits

  • Most respondents overestimated the amount of welfare spending on the unemployed and benefit fraud massively.
  • Less than 5% of the UK government’s welfare budget is spent directly on unemployment benefits, but the average public estimate was nearly 37%.
  • And while less than 3% of welfare benefits are claimed fraudulently, the UK public guessed that the figure was 28%.

How knowledge relates to political attitudes

  • Major differences could be seen according to people’s political and policy preferences.
  • People who favoured greater redistribution of wealth and more generous benefits answered more fact-based questions correctly, and gave more accurate spending and fraud estimates.


Overall, people who favour a more comprehensive welfare state demonstrate higher levels of knowledge of how the economy and welfare system in the UK work. This was true even when controlling for socioeconomic and demographic characteristics. This further translates into party political choices. Labour voters, on average, demonstrated a better overall understanding of benefits and the economy than Conservative voters.

Why understanding the economy matters

  • When the economy is struggling, it is important for people to know factual information about what they are personally entitled to.
  • Only about half of our respondents knew that all UK citizens who are employees are entitled to unemployment benefits if they lose their job.
  • Knowledge is difficult to measure, and the economy is a particularly complex topic.

Bed bugs are a global problem, yet we still know so little about how they spread

Retrieved on: 
Thursday, October 26, 2023

Bed bugs have recently exploded into the limelight amid widespread reports of a major outbreak in Paris.

Key Points: 
  • Bed bugs have recently exploded into the limelight amid widespread reports of a major outbreak in Paris.
  • The more people share photos of bed bug bites on social media, the more concerned we feel.
  • Indeed, data that confirms or denies the location and date of any bed bug cases is notoriously hard to find.

A seasonal spike

  • The same seasonal pattern and year-on-year increase was seen in the US city of Philadelphia between 2009 and 2011, and in two Chinese cities in 2012/13.
  • In New York between 2010 and 2020, the seasonal pattern was the same but the numbers did not increase.
  • Studies from the US and Australia both found the same seasonal pattern in internet searches for bed bugs, although the pattern in Australia was the opposite to the northern hemisphere.

What we know about bed bugs

  • It was much later in 1758 that the natural historian Carl Linnaeus added “lectularius” to their name, meaning bed or couch.
  • Bed bugs have a complex gut microbiota, which helps them extract all the nutrients they need from our blood.
  • My team put bed bugs in corrugated filter paper in the centre of a room, with clean and dirty clothes evenly spaced around them.
  • The bed bugs all left the filter paper, and made a beeline for the dirty clothes nearly every time.

How to stop their spread

  • If we could understand more about bed bug dispersal and spatial distribution, we would stand a better chance of stopping their spread.
  • According to the same report that confirmed the 2010 outbreak, bed bug numbers in New York are declining.
  • The city also passed a policy where, from 2010, landlords were required to report bed bug infestations to prospective tenants.

Monolith considers the cultural and social implications of new technology, without overdoing it

One of the socially redeeming features of mass media has always been its communal aspect, the fact people are drawn together into a shared experience based on network programming.

Key Points: 
  • One of the socially redeeming features of mass media has always been its communal aspect, the fact people are drawn together into a shared experience based on network programming.
  • Of course, this, in the English-speaking world at least, has been driven by the desire for profit through selling advertising space to corporations.
  • Her investigation takes her across the globe and back through time to the 1980s and the Cold War.
  • We watch as she interviews people, often using ethically dubious practices, and assembles the material entirely from inside her home.

What is the monolith?

  • We never definitively find out (which some viewers will surely find annoying).
  • The obscurity with which the film represents the bricks seems to call for this kind of allegorical reading.
  • Joining Sullivan are the voices of some well-known Australian actors including Damon Herriman, Kate Box and Erik Thomson.

The strange solitude of interpersonal communication

  • The strange solitude of interpersonal communication in the global information economy underpins the whole thing, and the screen is replete with a plethora of different technologies reflecting this – talking head videos online, audio recording, editing and streaming, mobile phones, smart houses, close-ups of digital text.
  • At the same time, we watch her go about the day-to-day business of living – making food in the kitchen, eating, showering at night – her deep solitude foregrounded throughout.
  • Despite this, Monolith remains an effective fantasy-thriller, remarkably engaging given its limitations – one location, one actor (well, two, including pet turtle Ian).
  • It’s also refreshing to see a high concept Australian film, as opposed to the usual social realist and period dramas.

Workplace tensions: How and when bystanders can make a difference

Retrieved on: 
Thursday, October 26, 2023

When employees hold political identities and perspectives that do not align with their co-workers, they perceive greater incivility from them, which can result in greater stress and burnout.

Key Points: 
  • When employees hold political identities and perspectives that do not align with their co-workers, they perceive greater incivility from them, which can result in greater stress and burnout.
  • Amid all this, bystander intervention has emerged as a key strategy for handling interpersonal conflicts.

The bystander’s dilemma

  • Bystanders often experience moral anger toward those who they perceive as perpetrators and empathy for those they perceive as targets.
  • These emotions, in turn, drive bystanders to support targets and penalize perpetrators.
  • And this fear is not without merit; research has found that perpetrators often retaliate when individuals voice concerns about mistreatment.
  • Even when bystanders do intervene, their actions can be ineffective, and, in some cases, counterproductive.
  • Threatening messages are likely to be met with resistance from the perpetrator, who is then inclined towards self-protective action.

The perpetrator’s perspective

  • This is especially the case when emotions are running high, making it difficult for individuals to consider alternative viewpoints.
  • In such instances, perpetrators are likely to condemn intervening bystanders and may even react to them punitively.
  • Talking to people in a safe setting and listening to different viewpoints can help perpetrators consider other perspectives.
  • Powerful perpetrators tend to be less concerned about the social implications of their actions and are more likely to become defensive.
  • In contrast, those with less power tend to be more dependent on others and, as a result, are more attuned to the expectations of their peers.
  • It can be hard to convince such individuals to change their mind, unless the bystander has the power to impose change.

Strategies for effective intervention


Our research offers several practical recommendations for effective bystander intervention in the workplace:
Carefully consider the best time to intervene. Unless there is a clear risk to the target (and a safe way to meaningfully intervene), it is best to wait until emotions have cooled.
Intervene in ways that allow the other person to maintain their sense of being a good person and colleague. Focus on addressing their behaviour, not their personal attributes, values or beliefs.
Recognize that powerful bystanders and those trusted by the other person are more effective in eliciting constructive responses than those with relatively less power.

  • As workplace tensions mirror global and social turmoil, the ability to step in, intervene and shape outcomes becomes ever more valuable, especially for vulnerable populations.
  • The essence of bystander intervention is not just about stopping a negative act, but also about fostering an environment where respect, growth and collaboration thrive.
