Researchers in the Syracuse University College of Engineering and Computer Science have developed a material – a new kind of shape memory polymer (SMP) – that could have major implications for health care.

SMPs are soft, rubbery, “smart” materials that can change shape in response to external stimuli like temperature changes or exposure to light. They can hold each shape indefinitely and turn back when triggered to do so.

SMPs have many potential biomedical applications...

Scientists at the University of British Columbia have discovered a new protein “switch” that could stop the progression of blood-poisoning, or sepsis, and increase the chances of surviving the life-threatening disease.

Sepsis, an inflammatory disease that arises when the body’s response to an infection injures its own tissues and organs, causes an estimated 14 million deaths every year. In a study published recently in Immunity, researchers examined the role of a protein called ABCF1 in regulating the progression of sepsis.

“Sepsis triggers an uncontrolled chain-reaction of inflammation in the body, leading to tissue damage, organ failure, and death,” said Hitesh Arora, co-lead author of the study who conducted this research as a PhD student at the Michael Smith...

Transplanting marrow from young lab mice to old mice preserves memory and learning skills. The findings support an emerging model that attributes cognitive decline, in part, to aging of blood cells, which are produced in bone marrow.

“While prior studies have shown that introducing blood from young mice can reverse cognitive decline in old mice, it is not well understood how this happens,” said Helen Goodridge, Ph...

In collaboration with the universities of Miami, Columbia and San Francisco, scient...
