and has no comments yet.
New research has shown how normally helpful brain cells can turn rogue and kill off other brain cells following injury or disease.Astrocytes have long been implicated in the pathology of a range of human neurodegenerative diseases or injuries including Alzheimer's, Huntington’s Parkinson’s disease, brain trauma and spinal cord injury.

Antarctic sea ice may be a source of mercury in Southern Ocean fish and birds

and has no comments yet.
New research has found methylmercury – a potent neurotoxin – in sea ice in the Southern Ocean.Published today in the journal Nature Microbiology, the results are the first to show that sea-ice bacteria can change mercury into methylmercury, a more toxic form that can contaminate the marine environment, including fish and birds.If ingested, methylmercury can travel to the brain, causing developmental and physical problems in foetuses, infants and children.

The million year old monkey

and has no comments yet.
An international team of scientists have dated a species of fossil monkey found across the Caribbean to just over 1 million years old.The discovery was made after the researchers recovered a fossil tibia (shin bone) belonging to the species of extinct monkey Antillothrix bernensis from an underwater cave in Altagracia Province, Dominican Republic. The fossil was embedded in a limestone rock that was dated using the Uranium-series technique.In a paper published this week in the well renowned international journal, the Journal of Human Evolution, the team use three-dimensional geometric morphometrics to confirm that the fossil tibia does indeed belong to Antillothrix bernensis, a primate that we now know existed on Hispaniola relatively unchanged for over a million years. This monkey, roughly the size of a small cat, was tree-dwelling and lived largely on a diet of fruit and leaves.
