Investigating plasma levels as a biomarker for Alzheimer's disease

20-Apr-2016

A Centre for Healthy Brain Ageing (CHeBA) paper presents the first detailed study of the relationship between plasma levels of two amyloid beta peptides (Aβ1-40 and Aβ1-42), brain volumetrics (measures studying the size of brain, which shrinks with Alzheimer's disease) and cognitive performance ...

World's thinnest lens to revolutionize cameras

15-Mar-2016

Scientists have created the world's thinnest lens, one two-thousandth the thickness of a human hair, opening the door to flexible computer displays and a revolution in miniature cameras. Lead researcher Dr Yuerui (Larry) Lu from The Australian National University (ANU) said the discovery hinged ...

Will blocking IL-17A help treat kidney disease?

26-Jan-2016

Many different diseases and insults can injure kidneys, resulting in kidney failure. Some autoimmune diseases damage glomeruli (the 'filtering units' of the kidney), while problems with the tubules (for example, impaired blood flow to the kidney at the time of renal transplantation, ...

Optical 'dog's nose' may hold key to breath analysis

09-Jul-2015

University of Adelaide researchers are developing a laser system for fast, non-invasive, onsite breath analysis for disease, potentially enabling screening for a range of diseases including diabetes, infections and various cancers in the future. The researchers have developed an instrument they ...

Scientists join forces to reveal the mass and shape of single molecules

04-May-2015

A microscopic tool, more than 1000 times thinner than the width of a single human hair, uses vibrations to simultaneously reveal the mass and the shape of a single molecule - a feat which has not been possible until now.The work was led by Professor John Sader at the University of Melbourne's ...

Epigenetic signatures that differentiate triple-negative breast cancers

04-Feb-2015

A new study, published in Nature Communications, compares the breast cancer DNA 'methylome' with that of healthy individuals. The methylome provides a new picture of the genome and shows how it is epigenetically 'decorated' with methyl groups, a process known as DNA 'methylation'. The study ...

New material puts a twist in light

28-Jul-2014

Scientists at The Australian National University (ANU) have uncovered the secret to twisting light at will. It is the latest step in the development of photonics, the faster, more compact and less carbon-hungry successor to electronics. A random find in the washing basket led the team to create ...

Small step towards growing tissue in the lab

21-Mar-2014

University of Adelaide mathematicians have devised a method for identifying how cell clusters have formed by analysing an image of the cluster. Published in the Journal of Theoretical Biology, their mathematical modelling tool will be useful in helping biologists and tissue engineers to move ...
