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…)
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.

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.

COLUMBIA, Mo. – Since 1992, the government’s Back-to-Sleep Campaign has encouraged parents to place infants on their backs to sleep. Still, more than 4,500 infants die unexpectedly during sleep each year in the United States. Now, a University of Missouri injury prevention researcher says that safe, separate sleep environments for infants are critical to preventing sudden unexpected infant deaths (SUIDs).
“Many of these SUIDs are due to unsafe sleep environments, and these deaths are totally preventable,” said Patricia Schnitzer, an associate professor in the MU Sinclair School of Nursing. “The safest place for infants to sleep is on their backs in their own cribs without soft bedding.” (more…)
Results from Berkeley Lab and University of Copenhagen Collaboration Contradict Current Views on Cancer Stem Cells
New findings in breast cancer research by an international team of scientists contradict the prevailing belief that only basal-like cells with stem cell qualities can form invasive tumors. Research led by Ole William Petersen at the University of Copenhagen (CU) and Mina Bissell of the Lawrence Berkeley National Laboratory (Berkeley Lab) and has shown that luminal-like cells with no detectable stem cell qualities can generate larger tumors than their basal-like counterparts. This may hold important implications for the diagnosis and the treatment of breast cancer as well as future personalized cancer medicine.(more…)
A young girl in Bridgeport, Connecticut, born with one of the most serious, life-threatening congenital heart defects known, is on her way to living a normal life thanks to Yale doctors who developed and performed the first operation of its kind in the United States.(more…)
Evolutionary biologists at the University of Toronto have found that individuals with low-quality genes may produce offspring with even more inferior chromosomes, possibly leading to the extinction of certain species over generations.(more…)
COLUMBUS, Ohio – Caring for a wife with breast cancer can have a measurable negative effect on men’s health, even years after the cancer diagnosis and completion of treatment, according to recent research.
Men who reported the highest levels of stress in relation to their wives’ cancer were at the highest risk for physical symptoms and weaker immune responses, the study showed. (more…)
