In America, a person who cuts your hair for $8 has to be licensed and obey minimum safety standards, but dietary supplements, which accounted for more than half the Class 1 drugs recalled by the U.S. Food and Drug Administration from 2004-12 (meaning they contained substances that could cause serious health problems or even death) are stuffed full of  unapproved medicinal ingredients, including steroids,  a new study from St. Michael's Hospital has found.

The majority of those recalled supplements were bodybuilding, weight loss or sexual enhancement products, said the study's lead author, Dr. Ziv Harel, and almost one-quarter of the substances are manufactured outside of the United States, he said in the paper.

Research has established that caffeine interferes with processes in cancer cells that control DNA repair, a finding that has generated interest in using the stimulant as a chemotherapy treatment, but given the toxic nature of caffeine at high doses, researchers from the University of Alberta have instead taken advantage of caffeine's lethal effects on cancer cells identify genes and pathways responsible for DNA repair.

The research team found that fruit flies with a mutant gene called melanoma antigen gene, or MAGE, appeared normal when fed a regular diet but died when fed food supplemented with caffeine. On closer inspection, they found the mutant flies' cells were super-sensitive to caffeine, with the drug triggering "cell suicide" - apoptosis. 

Researchers have taken a step forward in efforts to help people with memory loss tied to brain disorders, such as Alzheimer's disease. Using sea snail nerve cells, the scientists reversed memory loss by determining when the cells were primed for learning. The scientists were able to help the cells compensate for memory loss by retraining them through the use of optimized training schedules. 

This latest study builds on a 2012 investigation that pioneered this memory enhancement strategy. The 2012 study showed a significant increase in long-term memory in healthy sea snails called Aplysia californica, an animal that has a simple nervous system, but with cells having properties similar to other more advanced species including humans.

X-ray astronomy is only 50 years old but nothing shows the progress of the technology like a new view of a supernova scientists watched over a thousand years ago. 

Some people just don't know how to put patterns and colors together. Or anything about style.

Some of that is cultural, of course. No one really wears corsets any more, for example, and good luck finding anyone outside the Mid-East who knows what a caftan is. Some new technology may herald a future for fashion, its creator claims; computerized fabrics that change their color and their shape in response to movement.

The most powerful batteries on earth are only a few millimeters in size but a cellphone version can jump-start a dead car battery and then recharge the phone in the blink of an eye. 

Led by Professor William P. King, researchers at the University of Illinois at Urbana-Champaign show that the new microbatteries out-power even the best supercapacitors and could drive new applications in radio communications and compact electronics.
