Artificial spleen cleans up blood. Harvard’s Wyss Institute Magnetic nanobeads in the 'biospleen' device bind to Escherichia coli (left) and Staphylococcus aureus (right) and remove them from blood.
Researchers have developed a high-tech method to rid the body of infections — even those caused by unknown pathogens. A device inspired by the spleen can quickly clean blood of everything from Escherichia coli to Ebola, researchers report on 14 September in Nature Medicine1. Blood infections can be very difficult to treat, and can lead to sepsis, an often-fatal immune response. 7 Myths About How To Stay In Shape. Get fit.
Stay fit. Easy goals to set, but they're hard to achieve. See Which Health Supplements Aren't Backed By Science. There are a lot of fad diets and articles out there that tell you which commonplace and obscure supplements you should be adding to your diet.
But how do you discern the genuine from the bullsh*t? This graph by David McCandless from Information is Beautiful ranks hundreds of health supplements based on the amount of scientific research backing their big claims. The graph only used data from human trials that used a random placebo-control method. Supplements with the strongest evidence backing them are placed at the top. Working your way down the graph, the supplements are backed less and less by conclusive evidence. 3 Quick Ways to Relieve Neck Pain for Heavy Computer UsersVideo. Virtual Events, Webinars and Videos. Electrolytes are ions that carry an electrical charge and travels in and out of cells.
The most common types of electrolytes in your body are sodium, potassium, calcium, chloride, and magnesium. Electrolytes trigger an event called action potential. Action potentials are the signals your brain transmits through neurons to parts of your body to contract the muscle. The principal ions involved in action potentials are sodium and potassium.
As these two ions travel in and out of cells, the cells’ charge switch back and forth from negative to positive. La fabrique de micro-organes humains. NUMÉRIQUE.

This pill may be a cure for radiation poisoning. After the US dropped atomic bombs on the cities of Hiroshima and Nagasaki at the end of World War Two, more than 100,000 people died — many from exposure to radiation.
At high doses, radiation blasts through tissues, ruptures DNA strands and alters the rhythms of cell division. Disrupted cells cause nausea, diarrhea and fever, then dizziness, weakness and hair loss. Russian Man Will Become Subject Of First Human Head Transplant Ever Performed.

Perhaps most famously, doctors in Star Trek are able to patch up cuts and burns by instantly regenerating their patients' skin using a kind of medical ray gun. The injured crew of the Enterprise can return to action almost immediately instead of spending months recovering. La médecine sans médecin ? Dans cet essai, paru début 2015 aux éditions Gallimard, Guy Vallancien, chirurgien urologue et membre de l’Académie nationale de médecine, décrit l’émergence de ce qu’il propose d’appeler la « média médecine ».
New Method Could Reveal Your Entire Viral Infection History With A Single Drop Of Blood. By analyzing just a single drop of blood, scientists could reveal every virus you’ve ever been infected with. This new method, developed by researchers from Howard Hughes Medical Institute (HHMI), is called ‘Virscan’ and it could revolutionize existing diagnostics. Traditional blood tests, known as ELISA assays, are only able detect one pathogen at a time and scientists have yet to develop ELISA assays against all viruses. Child Revived Almost 2 Hours After "Drowning" - But How? Last Wednesday evening, a 22-month-old child tripped and fell into an icy tributary of Buffalo Creek, outside Mifflinburg, Pennsylvania. The boy was quickly swept downstream for about a quarter of a mile before being washed up on a grassy knoll, which was where a neighbor later found him.
The infant had no pulse and was not breathing at the time of discovery and may have been in the 1oC (34oF) water for as long as 30 minutes. According to PennLive, emergency services were immediately called and as soon as they arrived they began to perform CPR on him, which continued uninterrupted as they made their way to Evangelical Community Hospital before boarding a helicopter destined for Geisinger. Human Head Transplants Could Become A Reality By 2017. Head transplants, or body transplants depending on how you look at them, are not just a thing of quirky horror movies. The first documented procedure was carried out back in the ‘50s when surgeon and transplant pioneer Vladimir Demikhov grafted the head and forelimbs of a puppy onto the body of a different dog.
Disturbingly, he followed this with his more famous work, which involved the creation of two-headed dogs. Iodine - Drug information, side effects, and reviews.

Blood Test Could Predict Alzheimer’s 10 Years Before Symptoms Appear. An early diagnosis is necessary to intervene and slow down the progression of neurodegenerative disease, such as Alzheimer’s disease (AD). Unfortunately, the disease typically isn’t spotted until symptoms have already appeared and amyloid plaques have begun to accumulate and cause damage to the brain. A new blood test claims to be able to accurately identify Alzheimer’s disease 10 years before the onset of symptoms. The paper was published in The Journal of the Federation of American Societies for Experimental Biology. Lead author Dimitrios Kapogiannis from the National Institute on Aging in Baltimore presented the research this week at the 2014 meeting of the Society for Neuroscience in Washington, DC.
The blood test was performed on 174 patients with various degrees of neurological health: 84 of the participants were healthy adults, 20 were elderly adults with no dementia, and 70 had been diagnosed with AD.

Exponential Medicine: Data Deluge to Disrupt Healthcare This Decade You can’t really boil down four days, 59 speakers, and a few lovely musical interludes into a single word—but here goes.
If there was an overriding theme to this year’s Exponential Medicine it was, in my humble opinion, information. In his opening talk, Peter Diamandis said health and medicine are poised to undergo a greater transformation than any other industry or field in the next decade. Of course, he meant treatments and technology will meaningfully advance. Regenerative Medicine Has Huge Potential But It Does Not Come Cheap.
Regenerative medicine, where soft tissues, organs or bone are extended or regrown is an increasingly exciting field. Examples of work being done include bone grafting or growing a patient’s own cells in the laboratory and then re-implanting them onto a wound bed to help it heal. Or how about regeneration of the trachea, the cornea, nervous tissue, the human finger, the liver, and even the male urethra? While some regenerative treatments are already happening, others, such as lab-engineered liver cells, have the potential to change lives if they can be developed further.
