Australia’s beloved dolphin populations face growing pressures from environmental changes and human activity, increasing the need for reliable, accessible and non-invasive tools to monitor their health and support conservation and management. 

In a new study published in the Journal of Thermal Biology, marine mammal experts from Flinders University analysed more than 40,000 drone-based thermal images to test how accurately drones fitted with thermal cameras can measure dolphin surface temperature and respiration rates without the need for capture or invasive probes.

When a person suffers a stroke, physicians must restore blood flow to the brain as quickly as possible to save their life. But, ironically, that life-saving rush of blood can also trigger a second wave of damage — killing brain cells, fueling inflammation and increasing the odds of long-term disability.

Now, Northwestern University scientists have developed an injectable regenerative nanomaterial that helps protect the brain during this vulnerable window.

In a new preclinical study, the team delivered a single intravenous dose, immediately after restoring blood flow, in a mouse model of ischemic stroke, the most common type of stroke. The therapy successfully crossed the blood-brain barrier — a major challenge for most drugs — to reach and repair brain tissue. The material significantly reduced brain damage and showed no signs of side effects or organ toxicity.

A new study shows that millions of Britons could be ready to swap imported fish for home caught favourites like sardines, sprats and anchovies.

The new report reveals that more than 40 per cent of consumers are willing to experiment with fish they’ve never tried before.  The study suggests the UK is overlooking a major opportunity to improve national health and bolster local economies by embracing its own rich stocks of small, nutritious fish.

And the team say that now is the perfect time for Britain to rediscover its local seafood.
