Researchers have found physical differences in the brains of people who respond emotionally to others' feelings, compared to those who respond more rationally.

The work led by Robert Eres from the Monash University School of Psychological Sciences, pinpointed correlations between grey matter density and cognitive and affective empathy. The study looked at whether people who have more brain cells in certain areas of the brain are better at different types of empathy.

Imagine a classroom where children are unable to wait their turn or stay focused on their work. They are easily distracted, cannot remember basic instructions or hold enough information in their head to solve problems – skills teachers rely on in order to teach successfully.

These behavioral issues are all examples of problems that can arise from attachment issues – based on the relationship between children and their main caregiver.

When you think of iron, you probably think of anvils and suits made by Tony Stark - iron is ore that comes from a mine. 

Now imagine that half of the iron in that object owes its existence to bacteria living two and a half billion years ago. 

Clark Johnson, a professor of geoscience at the University of Wisconsin-Madison, and former postdoctoral researcher Weiqiang Li examined samples from the banded iron formation in Western Australia. Banded iron is the iron-rich rock found in ore deposits worldwide, from the proposed iron mine in Northern Wisconsin to the enormous mines of Western Australia. These ancient deposits, up to 150 meters deep, were begging for explanation. 

A new study is helping to shed light on latent tuberculosis and the bacteria's ability to hide in stem cells.

Some bone marrow stem cells reside in low oxygen (hypoxia) zones. These specialized zones are secured as immune cells and toxic chemicals cannot reach this zone. Hypoxia- activated cell signaling pathways may also protect the stem cells from dying or ageing.

A new study led by Forsyth Scientist Dr. Bikul Das has found that Mycobacterium tuberculosis (Mtb) hijack this protective hypoxic zone to hide intracellular to a special stem cell type. 

Using biofuel is one way to decrease the United States' dependence on oil. And switchgrass is an excellent candidate for biofuel production. It is an adaptable plant that can grow on millions of acres of U.S. lands that cannot support crop or food production. It is also a renewable resource but growing it and making it profitable can be complicated. 

It lacks qualities, such as high biomass yield, needed to maximize biofuel production. Alternative breeding methods may be the answer.

“Take your ear off for me, please,” Rosie Seelaus says to Randy James, who is sitting on a black exam chair in a special room designed for viewing colours in the Craniofacial Center on the Near West Side of Chicago.

He reaches up and detaches his right ear, which she created for him out of silicone seven years before. The ear is shabby, stained from skin oil and mottled by daily use. Viewed under various lights in the neutral, grey-walled room – daylight, incandescent, fluorescent – it remains a pasty beige.
