The mystery gene which helps mice survive virus infections

17-Aug-2022 - Researchers from UNSW Sydney have discovered that a particular transposable element, or jumping gene, in the genome has a profound effect on the immune response to virus infection. The findings in mice, published in Nature, provide new information about how the immune system is regulated, and ...

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 ...

New lab-on-a-chip device overcomes miniaturization problems

02-May-2014 - UNSW Australia chemists have invented a new type of tiny lab-on-a-chip device that could have a diverse range of applications, including to detect toxic gases, fabricate integrated circuits and screen biological molecules. The novel technique developed by the UNSW team involves printing a pattern ...

New type of biosensor is fast, super-sensitive

Detects one-billionth of a gram in minutes

05-Jun-2012 - A whole new class of biosensor that can detect exceptionally small traces of contaminants in liquids in just 40 minutes has been developed by a UNSW-led team of researchers.Known as a biochemiresistor, it meets a long-standing challenge to create a sensor that is not only super-sensitive to the ...

Tunable plastic thermometers

Scientists use an ion beam to produce conductive plastic films for electrical resistance thermometers

20-Dec-2010 - Researchers at the Universities of Queensland and New South Wales in Australia have discovered that the ability of a plastic to conduct electricity can be tuned by exposure to an ion beam. Usually plastics conduct electricity so poorly that they are used as the insulation around electrical ...
