Brain power: Wirelessly supplying power to the brain

by Dr. Jekyll in Lunatic Laboratories

Human and animal movements generate slight neural signals from their brain cells. These signals obtained using a neural interface are essential for realizing brain-machine interfaces (BMI). Such neural recording systems using wires to connect the implanted device to an external device can cause infections through the opening in the skull. One method of solving this issue is to develop a wireless neural interface that is fully implantable on the brain.

We can build it better: Synthetic biopathway turns agriculture waste into ‘green’ products

by Dr. Jekyll in Lunatic Laboratories

Researchers at the University of Minnesota have engineered a new synthetic biopathway that can more efficiently and cost-effectively turn agricultural waste, like corn stover and orange peels, into a variety of useful products ranging from spandex to chicken feed.

Holding Back: Inhibition

by Joshua Fisher in Text Savvy

I remember years ago being required to write math problems containing unnecessary information so that students would have to choose the information that they needed. But just making kids do something is not the same thing as teaching them something. It is, rather, a total cave to assessment obsession—we just found a way to call assessment "instruction"....

Anxious? Chronic stress and anxiety can damage the brain

by Dr. Jekyll in Lunatic Laboratories

A scientific review paper warns that people need to find ways to reduce chronic stress and anxiety in their lives or they may be at increased risk for developing depression and even dementia. Led by the Rotman Research Institute at Baycrest Health Sciences, the review examined brain areas impacted by chronic anxiety, fear and stress in animal and human studies that are already published....

Overwhelmed and depressed? Well, there may be a connection

by Dr. Jekyll in Lunatic Laboratories

Ever feel overwhelmed when you are depressed, well the good news is it isn't just you, the bad news is it's probably your brain. Regions of the brain that normally work together to process emotion become decoupled in people who experience multiple episodes of depression, neuroscientists report. The findings may help identify which patients will benefit from long term antidepressant treatment to prevent the recurrence of depressive episodes.

Perplexity Is Not Required for Learning

Pay attention! Attention neuron type identified

by Dr. Jekyll in Lunatic Laboratories

Researchers have identified for the first time a cell type in the brain of mice that is integral to attention. Moreover, by manipulating the activity of this cell type, the scientists were able to enhance attention in mice. The results add to the understanding of how the brain's frontal lobes work and control behaviour.

Stem cells regulate their own proliferation and their microenvironment

A study by researchers at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) has identified a new mechanism through which hematopoietic stem cells (HSCs) control both their own proliferation and the characteristics of the niche that houses them. This control is exercised by the protein E-Selectin Ligand-1 (ESL-1).... Read more »

Do Experts Make Bad Teachers? No.

by Joshua Fisher in Text Savvy

A pair of new studies has found that the stereotype of the aloof professor—you know, the one that is accomplished in her field but I'd like to see her come teach the kids in my school—might be, surprise surprise, a little unfair.

Researchers found that the superior content knowledge of mathematics professors (8 assistant professors and 7 full professors) relative to secondary teachers was associated with a significantly greater amount of conceptual explanations, as opposed to........ Read more »
