New study shows promise for first effective medicine to treat cocaine dependence

Posted: 25 Oct 2013 09:22 AM PDT

New research published in JAMA Psychiatry reveals that topiramate, a drug approved by the U.S. Food and Drug Administration (FDA) to treat epilepsy and migraine headaches, also could be the first reliable medication to help treat cocaine dependence.

Study Finds Natural Compound Can Be Used for 3-D Printing of Medical Implants

Posted: 25 Oct 2013 07:35 AM PDT

Researchers from North Carolina State University, the University of North Carolina at Chapel Hill and Laser Zentrum Hannover have discovered that a naturally-occurring compound can be incorporated into three-dimensional (3-D) printing processes to create medical implants out of non-toxic polymers. The compound is riboflavin, which is better known as vitamin B2.

An antibody fragment designed ameliorates first hallmarks of Alzheimer's disease in mice

Researchers at the Biosciences Unit of the Department of Biochemistry and Molecular Biology at the Universitat Autònoma de Barcelona (UAB), in collaboration with the UAB Institute of Neurosciences (INc), have conducted trials with mice by injecting a specific antibody fragment against soluble aggregates of the A peptide, responsible for the toxicity and cell death characteristic of Alzheimer's disease. The beneficial effects were seen at the behavioural, cellular and molecular levels five days after an intraperitoneal dose was administered.

Women's chronic pain is more complex, more severe

Posted: 25 Oct 2013 07:24 AM PDT

New research from the University of Adelaide has found that chronic pain in women is more complex and harder to treat than chronic pain in men.

The work, to be presented tomorrow at the Faculty of Pain Medicine spring meeting in Byron Bay, organised by the Australian and New Zealand College of Anaesthetists (ANZCA), suggest that men and women should be prescribed medications and treated for pain differently according to their gender.

Graphene can emit laser flashes

Graphene is considered the jack-of-all-trades of materials science: The two-dimensional honeycomb-shaped lattice made up of carbon atoms is stronger than steel and exhibits extremely high charge carrier mobilities. It is also transparent, lightweight and flexible. No wonder that there are plenty of applications for it – for example, in very fast transistors and flexible displays.
