Rockefeller University Scientists use algorithm to peer through opaque brains

Posted on July 21, 2017July 21, 2017 by adminedit

Trying to pinpoint signals from individual neurons within a block of brain tissue is like trying to count headlights in thick fog. A new algorithm, developed by researchers based at The Rockefeller University, brings this brain activity into focus. In research described June 26 in Nature Methods, the team, led by Rockefeller’s Alipasha Vaziri, used a light microscope-based technique to capture neural activity within a volume of mouse brain tissue at unprecedented speed. The algorithm allowed ...

Augusta University research suggest, age and obesity conspire to damage the tiny blood vessels that feed the heart, causing heart failure

Posted on July 21, 2017 by adminedit

Age and obesity appear to create a perfect storm that can reduce blood flow through the tiny blood vessels that directly feed our heart muscle and put us at risk for heart failure, scientists report. They call it “aged fat” and scientists now have evidence that the inflammation created by both age and fat have an additive effect that can thicken the walls of our coronary microvasculature without any evidence of the classic atherosclerotic plaque that many of us associate with heart disease....

Stanford researchers develop a new soft, growing robot

Posted on July 20, 2017 by adminedit

Imagine rescuers searching for people in the rubble of a collapsed building. Instead of digging through the debris by hand or having dogs sniff for signs of life, they bring out a small, air-tight cylinder. They place the device at the entrance of the debris and flip a switch. From one end of the cylinder, a tendril extends into the mass of stones and dirt, like a fast-climbing vine. A camera at the tip of the tendril gives rescuers a view of the otherwise unreachable places beneath the rubble. ...

Patients whose emergency surgery is delayed are at higher risk of death

Posted on July 10, 2017July 10, 2017 by adminedit

BACKGROUND: Delay of surgery for hip fracture is associated with increased risk of morbidity and mortality, but the effects of surgical delays on mortality and resource use in the context of other emergency surgeries is poorly described. Our objective was to measure the independent association between delay of emergency surgery and in-hospital mortality, length of stay and costs. METHODS: We identified all adult patients who underwent emergency noncardiac surgery between January 2012 an...

3D cell culture is an artificially-created environment in which biological cells are permitted to grow or interact with their surroundings in all three dimensions

Posted on June 17, 2017 by adminedit

3D cell culture is an artificially-created environment in which biological cells are permitted to grow or interact with their surroundings in all three dimensions. Unlike 2D environments (e.g. a petri dish), a 3D cell culture allows cells in vitro to grow in all directions, similar to how they would in vivo. These three-dimensional cultures are usually grown in bioreactors, small capsules in which the cells can grow into spheroids, or 3D cell colonies. Approximately 300 spheroids are usually cul...

Radboud University Netherlands research suggest learning to read in your thirties profoundly transforms brain networks

Posted on June 11, 2017June 11, 2017 by adminedit

Reading is such a modern cultural invention that, so far, there is no specific area in the human brain dedicated to it. An international team of scientists led by the Max Planck Institute (MPI) for Psycholinguistics in Nijmegen and the MPI for Human Cognitive and Brain Sciences in Leipzig have found that learning to read as an adult reconfigures brain areas hitherto assigned to different skills. Most strikingly, evolutionarily ancient structures - located deep inside the brain - are more fundame...

3D bioprinting is the process of creating cell patterns in a confined space using 3D printing technologies, where cell function and viability are preserved within the printed construct. Current 3D printing technology has advanced quickly in recent years, enabling people to print 3D models of non-living objects. More recently, researchers in the biomedicine have also begun to use this technology to print human organs and tissues with devices called “3D Bioprinters.” Wake Forest Institute for R...

Rush University medical Center research suggest, skin color is no shield against melanoma

Posted on June 10, 2017 by adminedit

Sidney Brown thought the mole on his nose was just an annoying pimple. He didn’t consider that it could be a cancerous tumor, because, Brown thought, “skin cancer is something white people get.” The misconception that people with more pigment — called melanin — in their skin cells are protected from cancer-causing ultraviolet rays nearly cost Brown his life. Non-whites have higher melanoma-related mortality rates Brown’s mole turned out to be a melanoma, the least common form of skin cancer...
