There are many many vaccines under development in the hope of becoming the second generation to follow the existing ones, or to fight the variants each year. These vaccines will have to go through repeated extensive trials - and a recent study has found that there may be a better way to assess suitability. And this may also help with tracking how the pandemic is evolving, especially with variants.

The spread of cancer is much-feared - but some tumours have only two or three metastases. And where secondary tumours are in inaccessible spots or surgery may not be indicated, radiation therapy might be able to help. Intensely focussed beams target several metasteses at the same time in a treatment called stereotactic body radiotherapy.

In a country as sunny as Australia, people are generally pretty aware of the risks of sunburn. But sometimes sunburn can necessitate a visit to a specialist burns unit.

Biobanking used to be called tissue banking, and involved keeping specimens from people with certain diseases so that they can be examined under the microscope or their genome analysed - to go back to and look at old samples with new eyes or technologies. It was sometimes an amateur affair with well-meaning surgeons, for example, having samples in their hospital freezer which they don't share. But things are changing, with a more organised approach and an increased interest in how it's done.

The one thing you'd think would have changed enormously over thousands of years, really hasn't. The microbiome in our mouths is really not too different from that of our primate ancestors.

A study has compared the weight of Australian women born in the 1970s with those born in the late 80s and early 90s. Those born later were almost 4 kgs heavier at the start of the study and gained weight at twice the rate over the same period of time as those born earlier.

The Baker Institute in Melbourne have published a review of the evidence of the toxicity of sitting for long periods, the relationship with physical inactivity in general, and the benefits of more movement throughout the day.

Some people test positive for the COVID virus for longer than others. While some have compromised immune systems, many have a normal immune system and are not infectious. A research group in Boston may know why this happens, and perhaps RNA from the virus has found a way into the DNA of the cells in the respiratory tract.

An injury to the eye is one of the leading causes of single-eye blindness in Australia. Until now we haven't had a good idea of just how much it costs the country.

A study has perhaps explained why chronic rhinosinusitis causes problems with thinking, memory, and fatigue - as well as the usual headache, sinus pain and blocked nose.

For most of human history men have lived longer than women but since the mid-19th century - when advances in obstetrics meant that women survived pregnancy and childbirth - women have lived longer than men. But in some countries it's been as high as 14 years.

A viral respiratory condition called bronchiolitis is the commonest reason for a baby under 12 months to be admitted to hospital. But there are variations in the care of babies with the condition. Australian and New Zealand researchers have carried out a trial to see how to raise the standard of care to match the evidence and guidelines.

Well over 5000 pre-term babies are born in Australia each year who are six weeks or more premature, and need intensive neonatal care to some extent. A French group has followed over 4000 children who were born at a gestation of 34 weeks or less through to the age of 5.

Research is showing that many kids born preterm can end up with developmental problems. Alison Shen's daughter was born at 25-and-a-half weeks. And while Alison and her husband had been warned that premmie babies sometimes have ongoing problems, it wasn't until the year before she started school that developmental problems became clear.

If Australia had met its original COVID vaccine targets, around 6 million Australians would have had their first dose by now. According to the ABC's data journalists, the number is less than half of that and the federal government is resisting setting new targets for mass vaccination. The Kirby Institute at the University of NSW has modelled how we could best deploy our limited supply of vaccines for maximal effect.
