Health News: FDA:17 Dietary supplements contain illegal ingredient ♦ Noroviruses spread several meters by air: ♦ New cellular response to radiation exposure

FDA:17 Dietary supplements contain illegal ingredient   The U.S. Food and Drug Administration (FDA) has advised 14 dietary supplement companies in warning letters dated April 24, 2015, that their total of 17 products include an ingredient on the Supplement Facts panel which is not approved for such use under federal law
Noroviruses spread several meters by air: Noroviruses, a group of viruses responsible for over 50 percent of global gastroenteritis cases, can spread by air up to several meters from an infected person. The discovery suggests that measures applied in hospitals during gastroenteritis outbreaks may be insufficient..
Engineering new blood vessels in people is one step closer to reality  Scientists moved a step closer toward coaxing the body into producing its own replacement blood vessels after discovering that suppressing parts of the innate immune system may raise the chances of a tissue engineered vascular graft success.
New cellular response to radiation exposure: Must we reconsider the risks of low doses? Almost the entire human genome is transcribed into RNA, but only a fraction of this is actually used to produce protein. The function of the majority of the RNA, the so-called 'non-coding transcriptome' remains an enigma. Some non-coding RNA families have been recognized through their shared structural features.
Impaired sleep linked to lower pain tolerance People with insomnia and other sleep problems have increased sensitivity to pain. The effect on pain tolerance appears strongest in people who suffer from both insomnia and chronic pain, who may benefit from treatments targeting both conditions.
