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...

...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

using the current serology technique, which produces an error of 3%. Thus, BLOODchip is currently the safest and most precise technique for genetically determining blood groups, enabling the reduction of adverse reactions in blood transfusions. T...
Alzheimer's prevention role discovered for prions
...been identified. It appears that the normal prions produced
by the body help to prevent the plaques that build up in the brain to cause Alzheimers disease. The possible function for the mysterious proteins was discovered by a team of scientists led by Medical Research Council funded scientist Professor Nigel ...

by populations of bacteria to kill off neighboring bacteria and public parks or buildings built by humans. In the presence of a durable good, cheaters can increase in numbers with no immediate consequences. For example, cheaters could still enjoy t...

Bioinformatics-related methods are featured in Cold Spring Harbor Protocols
...undertakings such as the Human Genome Project have produced
massive amounts of data. To make sense of it all, powerful mathematical and statistical algorithms were developed, resulting in the interdisciplinary field called bioinformatics. By probing genome sequence data with in silico tools, biologists can in...
