  • Why having sex really IS the best thing to do
  • is better for evolution than self-reproduction
  • Having sex allows us to evolve more effectively than species which reproduce without a partner, according to tests that claim to finally prove the long-held theory.
  • ...6 more annotations...
  • cording to the study by the University of Edinburgh.
  • Combining the genes of two parents – rather than one in the case of fruit flies, stick insects and other animals – allows for damaging DNA to be removed within a few generations.
  • Meanwhile, creatures who reproduce asexually are more likely to be lumbered with disease-causing genes

  • or muc
  • This is because individuals who inherit healthy genes tend to flourish and pass on their DNA to the next generatio

    well, I guess SEX is the best way to develop a super human for the future + I know everyone gonna love it :)

  • Patients with advanced heart disease who received an experimental stem cell therapy
  • Study authors described the trial as the largest to date to examine stem cell therapy as a route to repairing the heart in patients with chronic ischemic heart disease and left ventricular dysfunction.
  • injections of their own stem cells, taken from their bone marrow, into damaged areas of their hearts.
  • ...11 more annotations...
  • The patients -- 82 of whom were men -- all had chronic heart disease, along with either heart failure or angina or both, and their left ventricles were pumping at less than 45 percent of capacity.
  • None of the participant
  • eligible for revascularization surgery
  • heart disease was so advanced
  • Those who received the stem cell therapy saw a small but significant boost in the heart's ability to pump blood, measuring the increase from the heart's main pumping chamber at 2.7 percent more than placebo patients.
  • However, other factors showed no improvement
  • heart's maximum oxygen consumption did not change
  • defects in the heart were not healed by the treatment
  • This is the kind of information we need in order to move forward with the clinical use of stem cell therapy," said lead investigator Emerson Perin
  • "With this mapping procedure, we have a roadmap to the heart muscle," said Perin
  • Heart disease is the leading killer in the United States, claiming nearly 600,000 lives per year, according to the US Centers for Disease Control and Prevention.

    A recent experiment was done on elderly patients who had heart diseases, those that had progressed too far for coronary surgery. Patients were injected with their own stem cells in the bone marrow into areas in the heart. The pumping capacity did improve a little, but overall the oxygen use and the defects did not change. This is a stepping stone towards using stem cells to treat people in difficult situations where a normal surgery would not.
