Natural Killer (NK) cells have long been the soldiers of the immune system that prevents the growth and spread of cancers, and subduing this army of cells is one of the key ways that tumours take hold. Australian researchers have discovered a protein found in humans that prevents NK cells from ...
Scientists develop cheap and rapid way to identify antibiotic-resistant golden staph (MRSA)
A combination of off-the-shelf quantum dot nanotechnology and a smartphone camera soon could allow doctors to identify antibiotic-resistant bacteria in just 40 minutes, potentially saving patient lives. Staphylococcus aureus (golden staph), is a common form of bacterium that causes serious and ...
Ancient protein pumps could be key to new green polymers
The molecular machinery used by bacteria to resist chemicals designed to kill them could also help produce precursors for a new generation of nylon and other polymers, according to new research by scientists from Australia and the UK. "Resistance to artificial antiseptics appears to be a lucky ...
Engineers have mimicked the human brain with an electronic chip that uses light to create and modify memories
Researchers from RMIT University drew inspiration from an emerging tool in biotechnology - optogenetics - to develop a device that replicates the way the brain stores and loses information. Optogenetics allows scientists to delve into the body's electrical system with incredible precision, using ...
Scientists from The University of Queensland's Diamantina Institute have revealed the difference between a stem cell and other blood vessel cells using gene-sequencing technology. Leading skin cancer and stem cell researcher Professor Kiarash Khosrotehrani said the findings provided evidence of ...
New organ-on-chip possibilities
The new micro-device for fluid analysis just unveiled in Advanced Functional Materials will enable more tailored experiments in drug development and disease research. It could also transform water contamination testing and medical diagnosis in natural disaster zones, where its low cost, simple ...
Understanding these superglue proteins could help in the battle against antibiotic resistance
The discovery, published in Nature Communications by researchers from La Trobe University and the University of Queensland, provides details on how proteins in the outer membrane of bacteria - the bacteria's 'superglue' - are able to stick to and populate parts of the human body. This new ...
Before the first cup of coffee, many people are still not really approachable in the morning. But already the smell of the freshly brewed energy supplier awakens the senses and lets the brain start working. But why is that? Scientists at Monash University in Melbourne and the University of ...
The ability to read the genome - all the DNA of an organism - has vast potential to understand human health and disease. Researchers at the Garvan Institute of Medical Research and UNSW Sydney have published a method to take genome analysis 'offline', by adapting a computer algorithm that can ...
Self-sterilizing microneedles revolutionizing vaccination and drug delivery
Vaccinations are the world's frontline defence against infectious diseases yet despite decades of interventions, unsafe injection practices continue to expose billions of people to serious infection and disease. Now, new technology from the University of South Australia is revolutionising safe ...
