When we cut our skin, groups of cells rush en masse to the site to heal the wound. But the complicated mechanics of this collective cell movement — which are facilitated by rearrangements between each cell and its neighbors — have made it challenging for researchers to decipher what’s actually driving it. “If we can…
The entire set of our emotions is topographically represented in a small region of the brain, a 3 centimeters area of the cortex, report scientists in a study conducted at the IMT School for Advanced Studies Lucca, Italy. The discovery of this “map” of emotions comes from a work conducted by the Molecular Mind Laboratory…
January 24, 2020 – As we enter a new year and a new decade, many states have enacted legislation affecting the roles of advanced practice registered nurses (APRNs) in terms of practice authority, reimbursement, and prescriptive authority, according to the 32nd Annual Legislative Update in the January issue of The Nurse Practitioner, published by Wolters…
London, UK: A new study published in the journal Cephalalgia, the official journal of the International Headache Society, shows unprecedented data regarding the neuroanatomical influence on the treatment response of patients with trigeminal neuralgia. The study, entitled “Hippocampal and trigeminal nerve volume predict outcome of surgical treatment for trigeminal neuralgia”, was conducted by Dr. Tejas…
Approximately one-quarter of patients who are prescribed opioids for chronic pain misuse them, with five to 10 percent developing an opioid use disorder or addiction. In a new study, published Jan. 14, 2020 in PNAS, researchers at University of California San Diego School of Medicine found that opioid dependence produced permanent changes in the brains…
Reno, Nev. – To better understand the organization of the brain and the perceptual tendencies in humans, a team of four scientists are recording video from four head-mounted cameras – with eyetracking and head movement – and assembling a massive video database with more than 240 hours of first-person video that can be used by…
“Jumping genes” — bits of DNA that can move from one spot in the genome to another — are well-known for increasing genetic diversity over the long course of evolution. Now, new research at Washington University School of Medicine in St. Louis indicates that such genes, also called transposable elements, play another, more surprising role:…
There remains a controversy in scientific circles today regarding the value of lithium therapy in treating Alzheimer’s disease. Much of this stems from the fact that because the information gathered to date has been obtained using a multitude of differential approaches, conditions, formulations, timing and dosages of treatment, results are difficult to compare. In addition,…
The World Health Organization on Thursday decided not to declare the Wuhan coronavirus outbreak a global emergency, despite the spread of the dangerous respiratory infection from China to at least five other countries. Although the disease has reached beyond China, the number of cases in other countries is still relatively small, and the disease does…
The spread of a deadly respiratory virus has prompted the authorities to limit travel in cities in central China, including Wuhan, where the disease was first found last month. It has since spread to at least four other countries. The outbreak comes just before the start of the Lunar New Year holiday on Friday, as…
