A Botox discovery that could save lives

Researchers have discovered how Botox, a deadly neurotoxin, enters brain cells, allowing for potential therapeutic targets to be identified. The study, published in the EMBO Journal, reveals that Botox hijacks a complex of receptors to interrupt communication between nerves and muscle cells, causing paralysis.

Tick tock – the liver controls the circadian clock

Research reveals liver cells play a crucial role in regulating the body's internal circadian clock, influencing sleep patterns, hormone secretion, and metabolism. Studies on mice with humanized livers show that altered liver function can disrupt circadian rhythms, highlighting potential new treatments for metabolic diseases.

Singing humpback whales respond to wind noise, but not boats

Researchers found that humpback whales have a unique response to wind noise, singing louder in noisy conditions. In contrast, they do not exhibit an increased reaction to vessel noise from boats. This finding has implications for understanding whale behavior and potential consequences for breeding practices.

Understanding self-directed ageism

Self-directed ageism is common among older people due to internalized ageist beliefs, which can lead to decreased lifespan, poorer health, and reduced confidence. Interventions like positive social interactions between younger and older adults may help prevent negative views of ageing.

Stinging tree injects promise of pain relief

Researchers at University of Queensland have identified a novel pain pathway triggered by the Gympie-Gympie tree's toxins, which could lead to non-opioid pain relief. The gympietide toxin interacts with nerves after injection through fine needle-like hairs on the leaves and requires a partner protein called TMEM233 to function.

Whales give up singing to fight for love

Researchers from the University of Queensland found that humpback whales have shifted their mating behaviour, with males giving up singing and instead fighting for dominance. This change is believed to be due to the increased population size after whaling cessation, as larger groups may deter other males from approaching potential mates.

Snakes can hear more than you think

A University of Queensland study found that snakes can hear airborne sound and react to it, contrary to popular belief. The research used soundproof rooms and observed reactions from captive-bred snakes, revealing differences in responses based on genus and evolutionary pressures.

Mushrooms magnify memory by boosting nerve growth

Researchers from The University of Queensland have identified new active compounds in Hericium erinaceus that promote neuron projections, extending and connecting to other neurons. This discovery could lead to treatments and protection against neurodegenerative cognitive disorders such as Alzheimer's disease.

New technology may help inform brain stimulation

Researchers at the Queensland Brain Institute developed a new ultrafast fMRI technique to study brain activity. The technique revealed that brain activity follows preferential circuits depending on cell type organisation, and blood signals can reflect network organisation and cell type distribution.

Environment law fails to protect threatened species

Research by University of Queensland finds that the Environment Protection and Biodiversity Conservation Act is not effectively protecting threatened habitats. Projects deemed 'significant' or 'not significant' have resulted in similar habitat destruction, highlighting inconsistencies in referral decision-making processes.

Harnessing the healing power within our cells

Researchers have discovered a pathway in cells that could be used to reprogram the body's immune system to fight chronic inflammatory and infectious diseases. A molecule derived from glucose, ribulose-5-phosphate, has been found to stop bacteria from growing and dampen inflammatory responses.

Speeding up sugar's conversion into fuel

University of Queensland researchers have found a way to more efficiently convert sugarcane into isobutanol, a chemical used in fuels, plastics, and food additives. The cell-free method produces at least 10 times the amount of isobutanol as traditional methods, offering higher yields and more control over the production process.

Masks can put cognitive performance in check

A University of Queensland study analyzing almost three million chess moves found that wearing a mask reduces the average quality of player decisions due to annoyance caused by the masks. The effect subsides after four to six hours of playing, suggesting mask-wearing impact depends on task type and duration.
