Scientists Discovered How to Convert Donor Blood into Universal Type

A team of researchers from the University of British Columbia claims that they may have found a reliable way to convert a less-usable donor blood type into type O, a universal type that can be received by anyone.way to convert donor blood

With the help of a technique called metagenomics, the scientists managed to take a large number of microbes from a sample of human feces and get a snapshot of all the DNA found in the gut. After that, they isolated bacterial genomes from the sample and tested thousands of enzymes, pitting them against sugary proxies that resembled blood A and B antigens.

One enzyme was more effective at stripping away A antigens from red blood cells. Also, the researchers were able to combine the new enzyme with one that’s already known to remove B antigens from blood cells, providing a way to convert AB, A and B blood into type O.

Your Blood Type Determines the Risk of Being Attacked by Ticks

Scientists from the Check Republic discovered the evidence that ticks may prefer attacking people with a certain blood type. Tick, the blood-sucking parasites, can carry various bacteria, including bugs that cause the Lyme disease.blood type and your risk of tick attack

In the course of study, the researchers dropped a tiny sample of blood from blood types A, B, AB, and O onto a sterile layer of filter paper on a Petri dish in the laboratory. The analysis of the received results showed that the ticks preferred type A blood in the majority of cases — 36% of the tick chose the sample. Type B was found to be least “favorite” — only 15% of the parasite chose the respective samples.

Lead researcher Dr. Alena Zakovska says: “The presented study demonstrated that blood group might be one of the factors determining the feeding preferences of Ixodes ricinus ticks.”
