  • 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. More than 50% of the time, physicians cannot diagnose the cause of an infection that has prompted sepsis, and so they resort to antibiotics that attack a broad range of bacteria2. This approach is not always effective, and can lead to antibiotic resistance in bacteria.
  • To test the device, Ingber and his team infected rats with either E. coli or Staphylococcus aureus and filtered blood from some of the animals through the biospleen. Five hours after infection, 89% of the rats whose blood had been filtered were still alive, compared with only 14% of those that were infected but not treated.

  • the device had removed more than 90% of the bacteria from the rats' blood.
  • The researchers then tested whether the biospleen could handle the volume of blood in an average adult human — about 5 litres. They ran human blood containing a mixture of bacteria and fungi through the biospleen at a rate of 1 litre per hour, and found that the device removed most of the pathogens within five hours.
  • That degree of efficacy is probably enough to control an infection, Ingber says. Once the biospleen has removed most pathogens from the blood, antibiotics and the immune system can fight off remaining traces of infection — such as pathogens lodged in the organs, he says.

      In short, it remove enough pathogens to be an effective human treatment.

    When it comes to technology, the sex industry is no laggard, and as robots become more human-like in their appearance and abilities, US-based company TrueCompany is poised to launch Roxxxy - the world's first sex robot - that has many more capabilities than your average sex doll. Apart from having better defined physical features than previous dolls, Roxxxy has been programmed with her own personality and her manufacturers say she can listen, talk, carry on a conversation, feel your touch and respond to it, as well as move her private areas inside when she is being "utilized" to deliver an unforgettable erotic experience. There are even plans for a male version - Rocky the Robot.
