If you missed your morning coffee and now you have a headache and difficulty concentrating, you might be able to blame it on caffeine withdrawal. In general, the more caffeine consumed, the more severe withdrawal symptoms are likely to be, but as little as one standard cup of coffee a day can produce caffeine addiction, according to a Johns Hopkins study that reviewed over 170 years of caffeine withdrawal research.
Results of the Johns Hopkins study should result in caffeine withdrawal being included in the next edition of the DSM or the Diagnostic and Statistical Manual of Mental Disorders, considered the bible of mental disorders, and the diagnosis should be updated in the World Health Organizations ICD, or The International Statistical Classification of Diseases and Related Health Problems.
"Caffeine is the worlds most commonly used stimulant, and its cheap and readily available so people can maintain their use of caffeine quite easily," says Roland Griffiths, Ph.D., professor of psychiatry and neuroscience at Johns Hopkins. "The latest research demonstrates, however, that when people dont get their usual dose they can suffer a range of withdrawal symptoms, including headache, fatigue, difficulty concentrating. They may even feel like they have the flu with nausea and muscle pain."

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
