’Velcro’ DNA origami helps build nanorobotic Meccano
The nanorobots developed by Dr Minh Luu and Dr Shelley Wickham could be used to deploy targeted cancer drugs, make futuristic materials that respond to their environments and find uses in creating energy-efficient signal processing. Nanoscale 'dinosaur' Object imaged using the cryo-electron microscope at the University of Sydney Microscopy and Microanalysis facility is just 250 nanometres wide.

Thirty-seven percent increase in deliberate self-poisonings among girls during COVID-19 lockdowns
A new study reveals a 37 percent increase in deliberate self-poisonings among female children and adolescents over the last four years. The increase is strongly correlated with COVID-19 pandemic restrictions. Published in the  Australian and New Zealand Journal of Psychiatry , the study found rates of deliberate self-poisoning were 84 percent higher among those aged 5-14 years, and 36 percent higher among those aged 15-19 years over March 2020 - December 2023 compared with 2018-19.

'Sleepy cannabis': first objective study to show cannabinol increases sleep
’Sleepy cannabis’: first objective study to show cannabinol increases sleep
Research at the University of Sydney Lambert Initiative shows that cannabinol increases both REM and non-REM sleep in rats. Human trials are now under way. Research by scientists at the University of Sydney has identified a constituent in the cannabis plant that improves sleep. Their report is the first to use objective measures to show the component, known as cannabinol (CBN), increases sleep in rats.

Standing more may not reduce cardiovascular disease risk, could increase circulatory disease
Over the long-term, standing more compared with sitting does not improve cardiovascular health, and could increase the risk of circulatory issues related to standing, such as varicose veins and deep vein thrombosis. Standing has gained popularity among people looking to offset the harms of a sedentary lifestyle often caused by spending long days sitting in front of the computer, television or driving wheel. Standing desks have become a popular option among office workers, and in other industries like retail, workers may opt to stand instead of sit.

How to stop an elephant destroying your crops and trees
How to stop an elephant destroying your crops and trees
To deter an elephant, think like an elephant. Dr Patrick Finnerty uses methods developed to ward off hungry wallabies in Australia to see if they'll work on pachyderms in South Africa. The results are promising. Elephant numbers are surging in southern Africa, with fewer natural predators, reduced hunting pressure and feeding by farmers and tourist operators.

Severe impact of button battery injuries in young children
Button batteries power numerous commonly used devices in the home. A study examining injuries from button battery ingestion found a combination of young age of the child, button battery size and delayed diagnosis creates a 'perfect storm' that increases the chance of severe injuries and death. A University of Sydney-led review has found it can take less than six hours after a child has swallowed a button battery for severe injuries and complications to occur.

New antidote for cobra bites discovered using CRISPR technology
New antidote for cobra bites discovered using CRISPR technology
Snakes kill more than 100,000 people a year. Cobra antivenom is expensive and doesn't treat the necrosis of flesh caused by the bite. Working with colleagues in the UK, Professor Greg Neely's team has identified heparin as an antidote to cobra venom. Scientists at the University of Sydney and Liverpool School of Tropical Medicine have made a remarkable discovery: a commonly used blood thinner, heparin, can be repurposed as an inexpensive antidote for cobra venom.
