Opioid Dependence Found to Permanently Change Brains of Rats

University of California San Diego Health

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, UC San Diego researchers found that opioid dependence produced permanent changes in the brains of rats.

What’s MER? It’s a Way to Measure Quantum Materials, and It’s Telling Us New and Interesting Things

Ames Laboratory

Experimental physicists have combined several measurements of quantum materials into one in their ongoing quest to learn more about manipulating and controlling the behavior of them for possible applications. They even coined a term for it-- Magneto-elastoresistance, or MER.

Your Brain: Individual and Unique

American Technion Society

New findings show that individual variations in the brain’s structural connectome (map of neural connections) define a specific structural fingerprint with a direct impact on the functional organization of individual brains.

Researchers Suggest a Pathway to Reverse the Genetic Defect of Friedreich’s Ataxia

Tufts University

Scientists report that the genetic anomaly causing the neurodegenerative disease Friedreich’s ataxia – the multiple repetition of a three letter DNA sequence – could potentially be reversed by enhancing a natural process that contracts the repetitive sequences in living tissue.

Researchers Identify Key Structure of C. Difficle Bacteria That Could Lead to Future Treatments

University of Maryland Medical Center

– Researchers from the University of Maryland School of Medicine and their colleagues have identified the structure of the most lethal toxin produced by certain strains of Clostridium difficile bacteria, a potentially deadly infection associated with the use of antibiotics. The researchers mapped out the delivery and binding components of the toxin, which could pave the way for new drugs to neutralize it.

Life could have emerged from lakes with high phosphorus

University of Washington

Life as we know it requires phosphorus, which is scarce. How did the early Earth supply this key ingredient? A University of Washington study, published Dec. 30 in the Proceedings of the National Academy of Sciences, finds answers in certain types of carbonate-rich lakes.
