ANN ARBOR, Mich.— Chronic migraine sufferers saw significant pain relief after four weeks of electrical brain stimulation in the part of the brain responsible for voluntary movement, the motor cortex, according to a new study. (more…)
Berkeley Scientists Create Graphene Liquid Cells for Electron Microscopy Studies of Nanocrystal Formation
They won’t be coming soon to a multiplex near you, but movies showing the growth of platinum nanocrystals at the atomic-scale in real-time have blockbuster potential. A team of scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley has developed a technique for encapsulating liquids of nanocrystals between layers of graphene so that chemical reactions in the liquids can be imaged with an electron microscope. With this technique, movies can be made that provide unprecedented direct observations of physical, chemical and biological phenomena that take place in liquids on the nanometer scale. (more…)
In his recently published book, Family Consequences of Children’s Disabilities, Dennis Hogan offers the first comprehensive account of families of children with disabilities. He talked with Courtney Coelho about his findings, including some of the more surprising ways having a child with a disability can affect the family structure.
Families of children with disabilities often face a plethora of challenges, ranging from the financial to the emotional. Still, little research has been done to document exactly how families are affected by a child with a disablity. Dennis Hogan’s recently published book, Family Consequences of Children’s Disabilities (Russell Sage Foundation), is the first comprehensive account of these experiences. Motivated by his own experience of growing up with a brother with Down syndrome, Hogan, the Robert E. Turner Distinguished Professor of Population Studies, merged existing data with interviews with more than two dozen family members of disabled children. He talked with Courtney Coelho about his findings, including some of the more surprising ways having a child with a disability can affect the family structure. (more…)
The fragile and rapidly changing Arctic region is home to large reservoirs of methane, a potent greenhouse gas. As Earth’s climate warms, the methane, frozen in reservoirs stored in Arctic tundra soils or marine sediments, is vulnerable to being released into the atmosphere, where it can add to global warming. Now a multi-institutional study by Eric Kort of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., has uncovered a surprising and potentially important new source of Arctic methane: the ocean itself.

WASHINGTON – Biologists from the Papua New Guinea National Museum and the U.S. Geological Survey have discovered a new species of gecko, adorned like a bumblebee with black-and-gold bands and rows of skin nodules that enhance its camouflage on the tropical forest floor. (more…)
Researchers at the University of Montreal’s Sainte-Justine Hospital have identified how neural cells are able to build up resistance to opioid pain drugs within hours. “A better understanding of these mechanisms will enable us to design drugs that avoid body resistance to these drugs and produce longer therapeutic responses, including longer-acting opioid analgesics”, lead author Dr. Graciela Pineyro said.
Humans have known about the usefulness of opioids, which are often harvested from poppy plants, for centuries, but we have very little insight into how they lose their effectiveness in the hours, days and weeks following the first dose. “Our study revealed cellular and molecular mechanisms within our bodies that enable us to develop resistance to this medication, or what scientists call drug tolerance,” she added.

UA computer science doctoral student Federico Cirett is using new technology to predict, in advance, when people will make a mistake. He’s been testing subjects taking the SAT exam in math.
Our bodies and brains tend to give us good cues about when we are becoming stressed, fatigued or overwhelmed.
But what if, with near exact precision, you could predict when heightened levels of fatigue were about to cause you to make a mistake?
University of Arizona doctoral student Federico Cirett believes he’s found a way – and with about 80 percent accuracy. (more…)
Study shows religious participation and spirituality processed in different cerebral regions
COLUMBIA, Mo. – Scientists have speculated that the human brain features a “God spot,” one distinct area of the brain responsible for spirituality. Now, University of Missouri researchers have completed research that indicates spirituality is a complex phenomenon, and multiple areas of the brain are responsible for the many aspects of spiritual experiences.
