The discovery opens up for new potential methods of early intervention . Alzheimer’s disease is the most common form of dementia and strikes about 20,000 people in Sweden every year. Researchers now show that a metabolic increase in the mitochondria , the cellular power plants, is an early indicator of the disease.  Per Nilsson.

The increase in metabolism in young mice was followed by synaptic changes caused by disruption to the cellular recycling system (a process known as autophagy ), a finding that was awarded the N obel Prize...

DOI: 10.1002/smll.202305469 Researchers at Flinders University have taken a significant leap in the field of wound care using an innovative approach . By deploying an argon atmospheric plasma jet , they have successfully transformed Spirulina maxima , a blue-green microalgae , into ultrathin bioactive coatings . These coatings not only t ackle bacterial infections but als o promote faster wound healing and possess potent anti-inflammatory properties . This holds promise especially for the treatment of ch...
