Saliva can be used to diagnose the presence and transmission of COVID-19, and to monitor immunity to SARS-Cov-2.
Astronomers have observed the full process of material spiralling into a distant neutron star, triggering an X-ray outburst thousands of times brighter than our Sun.
Bricks and construction materials could be made from recycled PVC, waste plant fibres or sand with the help of a new kind of rubber polymer.
Parts of the Eastern Highlands of Victoria may be as young as five million years old — not 90 million years old as previously thought.
The biomarker discovery could be used as the basis for a highly effective and simple diagnostic blood test to help detect prevalent cases of TB in the community.
Researchers have been converting bioethanol into products including synthetic diesel, gasoline and jet fuel that have nearly the same properties as fossil fuels.
The new diagnostic approach has the potential to enhance infectious diseases surveillance, and so is now being adapted to track immunity to COVID-19.
Reversions to asexual reproduction are rare in nature, so this may be the first time that the genetic basis of such a phenomenon has been discovered.
Unlike in the influenza pandemic in 1918, today we are better equipped to identify the elusive bug responsible for COVID-19.
Exactly how massive galaxies attain their size is poorly understood, but now a combination of observation and modelling has provided a vital clue.
Researchers have developed a new method to enable more timely diagnosis and treatment of urological cancers, ie, prostate, bladder and kidney cancers.
A new blood test can accurately detect more than 50 types of cancer and identify in which tissue the cancer originated, often before there are any clinical signs or symptoms.
Chemists, physicists and engineers have transformed optical fibres into photocatalytic microreactors that convert water into hydrogen fuel using solar energy.
Researchers have created a new technique that speeds up the development of seeds, producing better quality and more abundant pulse crops as a result.
