Soil particles found to boost prion's capacity to infect
...ection. Prions are an abnormal form of a protein produced normally by the body. Tough as nails, they can persist in the environment for long periods of time and retain their infectious capabilities. It is believed that prions may persist in the soil around the carcasses of dead animals and other locations w...Amoebae control cheating by keeping it in the family
... and reproduction. On their own, cheater A mutants produced few or no spores, but in mixed colonies they could thrive by cheating and avoiding service in the stalk. Foster and Mehdiabadi found cheater A spread readily within low-related colonies, and exacted a high toll by reducing the colonies' ability to re...Tracing Parkinson's lethal mechanism
...chemically active reactive oxygen species that are produced inside mitochondria in the process of generating energy for the cell. Specifically, the researchers found that treating neurons with MPTP activates Cdk5 to switch off Prx2. Whats more, they found that activating Prx2 in MPTP-treated mice prevented ...Progenika Biopharma presents a biochip that guarantees safety in blood transfusions
