Applying electrical stimulation to the scalp and the underlying motor regions of the brain could make you more skilled at delicate tasks. Research published today in the open access journal BMC Neuroscience shows that a non-invasive brain-stimulation technique, transcranial direct current stimulation (tDCS), is able to improve the use of a person’s non-dominant hand. 

Did the Bible's King David and his son Solomon control the copper industry in present-day southern Jordan? The possibility is raised once again by research reported in the Proceedings of the National Academy of Sciences.

Off-label prescription of a drug is generally legal, but promotion of off-label uses by a drug manufacturer is illegal. In an article in this week's PLoS Medicine, two physician researchers describe the techniques that they say drug companies use to covertly promote off-label use, even when such promotion is illegal.

Adriane Fugh-Berman (Georgetown University Medical Center) and Douglas Melnick (a preventive medicine physician working in North Hollywood, California) argue that while off-label drug use is "sometimes unavoidable" and sometimes "demonstrably beneficial," it has also been linked with serious side effects. Off-label drug use, they say, "should be undertaken with care and caution due to the uncontrolled experiment to which a patient is being subjected."

Bioniche Life Sciences Inc., a research-based, technology-driven Canadian biopharmaceutical company, today announced that Econiche(TM), the world's first vaccine designed to reduce the shedding by cattle of Escherichia coli (E. coli) O157:H7, has received full licensing approval from the Canadian Food Inspection Agency (CFIA). Econiche is now available for unrestricted use by Canadian cattle producers and their veterinarians.

Econiche is a Canadian discovery developed by Bioniche Life Sciences Inc. The vaccine has the potential to significantly reduce the amount of E. coli O157 shed into the environment by beef and dairy cattle and, in turn, reduce the risk to human health.

The ability to make fire millennia ago was likely a key factor in the migration of prehistoric hominids from Africa into Eurasia, a researcher at the Hebrew University of Jerusalem's Institute of Archaeology believes on the basis of findings at the Gesher Benot Ya'aqov archaeological site in Israel. 

Earlier excavations there, carried out under the direction of Prof. Naama Goren-Inbar of the Institute of Archaeology, showed that the occupants of the site – who are identified as being part of the Acheulian culture that arose in Africa about 1.6 million years ago -- had mastered fire-making ability as long as 790,000 years ago. This revelation pushed back previously accepted dates for man's fire-making ability by a half-million years. 

Fraunhofer researchers from Stuttgart have developed a new technology that enables the production of energy-autonomous, low-maintenance sensors.   The original application is sensors in air compression systems.  At present, those sensors are either battery-driven or connected by complex wiring. This often makes it very difficult or even impossible to install sensors in places that are hard to reach.

The solution; make electricity from air or water in a closed environment - with no movable parts.
