3D Tissue Imaging and Skilful Subordinate Meerkats
3D Imaging of Human Tissue
3d images of human tissues can now be created using a technique developed by scientists at the University of Leeds.
By scanning hundreds of slides of sliced tissues segments at once and converting them into high resolution digital images, the software, developed by Derek Magee, then aligns these to produce detailed, multi-coloured images in 3 dimensions, with over 400 created to date.
The technique can be used on numerous tissue types including tumours and samples of liver disease, and enables samples to be rotated on a computer screen and monitored from any angle.
New compound to treat Autism
A drug to treat the symptoms of autism has been identified by scientists at the National Institutes of Mental Health in the US.
Working with inbred mice displaying signs of autism such as unusual social interactions, excessive jumping and repetitive self-grooming, Jacqueline Crawley and colleagues found that when the mice were injected with the
compound GRN-529 - which regulates glutamate release in the brain - these behaviours were significantly reduced.
Climate warming by wind turbines
Large wind farms may be affecting local weather and climate in the US.
With the US wind industry growing rapidly in recent years, scientists at the University of Illinois analysed satellite data for the land surface temperatures of four of the World's largest wind farms in Texas, to see their effect on local land surface temperatures from 2003 to 2011.
The team found a warming effect of up to 0.72 °C per decade when compared to nearby regions lacking these farms.
Somnath Baidya Roy co-authored the study.
Subordinate Meerkats are the best problem solvers
subordinate members of a meerkat social group are the best at solving problems.
Alex Thornton from the University of Cambridge set tasks for 7 groups of wild meerkats where the animals were required to open or break into transparent containers to reach the scorpion supper located inside.
The team found that lower ranking members of the group, and particularly males at this rank, were the most successful at solving the task.
And that work was published in the journal Animal Behaviour.
