University of South Australia researchers have identified an enzyme that may help to curb chronic kidney disease, which affects approximately 700 million people worldwide.

This enzyme, NEDD4-2, is critical for kidney health, says UniSA Centre for Cancer Biology scientist Dr Jantina Manning in a new paper published this month in Cell Death & Disease.

The early career researcher and her colleagues, including 2020 SA Scientist of the Year Professor Sharad Kumar, have shown in an animal study the correlation between a high salt diet, low levels of NEDD4-2 and advanced kidney disease.

While a high salt diet can exacerbate some forms of kidney disease, until now, researchers did not realise that NEDD4-2 plays a role in promoting this salt-induced k...

An international team of astrophysicists from Southampton, Oxford and South Africa have detected a very hot, dense outflowing wind close to a black hole at least 25,000 light-years from Earth.

Lead researcher Professor Phil Charles from the University of Southampton explained that the gas (ionised helium and hydrogen) was emitted in bursts which repeated every 8 minutes, the first time this behaviour has been seen around a black hole. The findings have been published in the journal Monthly Notices of the Royal Astronomical Society.

The object Professor Charles’ team studied was Swift J1357...

Urinary sodium excretion, blood pressure, cardiovascular disease, and mortality: a community-level prospective epidemiological cohort study. The Lancet, 2018; 392 (10146): 496 DOI: 10.1016/S0140-6736(18)31376-X

Public health strategies should be based on best evidence. New research shows that for the vast majority of individuals, sodium consumption does not increase health risks except for those who eat > five grams a day, the equivalent of 2.5 teaspoons of salt. Fewer than 5% of individuals in developed countries exceed that level.

The large, international study also shows that even for those individuals there is good news...
