A new study provides fresh evidence that the decline in the capacity of brain cells to change, called “plasticity,” rather than a decline in total cell number may underlie some of the sensory and cognitive declines associated with normal brain aging. Scientists at MIT’s Picower Institute for Learning and memory show that inhibitory interneurons in […]

How the brain biases beliefs: Proposed neural circuit may underlie motivation to cling to desirable notions about the future
People’s motivation to cling to desirable notions about future outlooks results from interactions between prefrontal cortex regions, according to a human neuroimaging study published in JNeurosci. Bojana Kuzmanovic and colleagues uncovered circuits in the brain that support belief updating by asking participants to estimate their own and a peer’s likelihood of experiencing an adverse life […]
Discovery presents treatment hope for Alzheimer’s and other neurodegenerative diseases
There is new hope for the treatment of Alzheimer’s and other neurological diseases following a ground-breaking discovery made by an Australian-Chinese research collaboration. Researchers from the University of South Australia and the Third Military Medical University in China have discovered a signal pathway within cells, and also invented a potential drug that could stop degeneration […]
Brain iron levels may predict multiple sclerosis disabilities
A new, highly accurate MRI technique can monitor iron levels in the brains of multiple sclerosis (MS) patients and help identify those at a higher risk for developing physical disability, according to a study published in the journal Radiology. MS is a disease that attacks three critical components of the central nervous system: the neurons […]
How does Parkinson’s disease develop? Study raises doubts on theory of Parkinson’s disease
Parkinson’s disease was first described by a British doctor more than 200 years’ ago. The exact causes of this neurodegenerative disease are still unknown. In a study recently published in eLife, a team of researchers led by Prof. Henning Stahlberg from the Biozentrum of the University of Basel has now questioned the previous understanding of […]
New method discovered to view proteins inside human cells: Scientists develop tagging device using Ferritin
Scientists at the University of Warwick have created a new way to view proteins that are inside human cells. Using Ferritin, a large protein shell that our cells use to store iron, the researchers have found a method they have called FerriTag that allows an electron microscope (EM) to view proteins precisely unlike current methods. […]
New nerve gas detector built with Legos and a smartphone
Researchers at The University of Texas at Austin have designed a way to sense dangerous chemicals using, in part, a simple rig consisting of a smartphone and a box made from Lego bricks, which could help first responders and scientists in the field identify deadly and difficult-to-detect nerve agents such as VX and sarin. The […]
