An international team of researchers, including scientists from the University of Dundee have announced that cyanobacteria (blue-green algae) found throughout the world may produce a toxin linked to certain types of neurological disease.
Researchers have previously proposed a link between beta-methyl-amino-alanine (BMAA), a neurotoxic amino acid found in cyanobacteria and an Alzheimer’s-like neurodegenerative disease suffered by the Chamorro people on Guam in the Pacific. The Chamorro people eat the seeds from cycads, plants found only in warm regions of the world which were found to produce BMAA.
Dr. Paul Cox, Director of the Institute for Ethnomedicine of the National Tropical Botanical Garden in Hawaii, and his colleagues found that BMAA is produced by a cyanobacterium resident in special roots of the cycad. Interest increased when BMAA was found in brain tissues of several Alzheimer’s disease patients in Canada.

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.
Researchers of the “Micro, Nano and Molecular Systems” Lab at the Max Planck Institute for Intelligent Systems in Stuttgart, together with an international...
