Supercooled kidneys have been transplanted into pigs in a “landmark achievement”

Supercooled kidneys have been transplanted into pigs in a “landmark achievement”

Published by Miika Tikkanen

Supercooled kidneys To test their device, Powell Palm and his colleagues first removed single kidneys from pigs. The organs were flushed with the same commonly used solution to remove the blood, just as transplant organs are. The team then kept some kidneys on ice for either two hours or 24 hours, to mimic standard conditions used in human transplantation. They also put some of the removed kidneys in their device for 24, 48, or 72 hours. The stored kidneys were then each transplanted back into the original donor pigs. Each pig’s second kidney was removed in the same procedure, leaving each animal with only the kidney that had been stored, and reimplanted. Once the 24-hour supercooled kidneys were transplanted, they immediately began producing urine—a key indication that they were working. The team members also measured other markers of kidney function and found that the organs appeared to be working normally within about 10 days of being transplanted. A kidney that was supercooled for 72 hours recovers once it is transplanted back into a pig.COURTESY RONALD …

Attribution Theory and Achievement Considerations

Attribution Theory and Achievement Considerations

Published by Jenni Sidey

The research indicates that, from an attribution theory perspective, when it comes to advancing potential (irrespective of the field or discipline), there are four factors that influence a person’s motivation to positively engage and learn. These four factors are identified as ability, effort, task difficulty, and luck (Weiner, 1979, 1985) Ability is thought of as being an internal stable factor over which a person may not think they have any control. However, one should consider that the ability to control one’s own learning may become available to an individual if they actively engage in their learning. This active learning engagement has the potential to change neurological pathways, leading to changes in cognitive and skill-acquisition capacities, as well as advances in knowledge, potential, insight, and creativity (Arrowsmith-Young, 2012; Coyle, 2009; Doidge, 2010, 2015). Effort is thought of as being an internal and unstable factor over which a learner has, if they so choose, to exercise a great deal of control. Effort is about self-initiated, self-directed motivation for all tasks and for advancing learning potential and overall …

Sign up for the Starts With a Bang newsletter Travel the universe with Dr. Ethan Siegel as he answers the biggest questions of all. One of the most remarkable facts about the Universe is simply that, over the past couple of centuries, humanity has actually been able to make sense of much of it at a basic, fundamental level. We’ve determined what all of the luminous and light-blocking material, plus radiation, is made of: the normal matter and energy in our Universe that consists of particles within the Standard Model. We’ve discovered black holes and have come to understand how gravity and the expanding Universe works: governed by the laws of Einstein’s General Relativity. And we understand the rules governing how particles interact: through the strong nuclear, weak nuclear, and electromagnetic forces, as dictated by quantum field theory. While these developments occurred both theoretically as well as observationally and experimentally, this picture has truly been cemented over the last 50 years by a large suite of data: collected from precise particle collider and detector experiments …
