Absent the creation of a personalized, living avatar, computer simulations will go a long way toward helping doctors figure out what to do about your health. Sophisticated models will be able to look at your heart and predict future coronary problems, for instance. Researchers at the University of Pennsylvania are designing new simulations with virtual blood, improving the prospects for this type of tech.
Anyone who has ever donated blood has learned his or her blood type, such as AB, O negative, etc., which will be matched to a recipient with the same blood type. If blood types do not match, a recipient’s immune system could reject the transfusion, a potentially fatal proposition. But a new method masks the type of donated red blood cells, possibly eliminating the need to test types and making it easier to give and receive blood.
Canadian researchers have turned skin cells into blood cells, a breakthrough that could lead to new cancer therapies while avoiding the controversial use of stem cells.
With the new technique, people who need blood for surgery, cancer treatment or other conditions could have a ready supply of their own blood, made from a patch of skin.
We often think of our blood as specifically tasked with carrying oxygen to our brains and other organs, but it's also a living fluid, changing up its duties in response to various stimuli. To better understand -- and anticipate -- one aspect of this complicated biology, researchers have trained a neural network computer to model how platelets in the blood react to complicated conditions like those experienced during heart attack or stroke.
When a wounded patient begins bleeding, the most commonly employed solution is decidedly low-tech: apply pressure. But a group of medical researchers have developed injectible synthetic nanoparticles that could cut bleeding time in half.
