From the ACS Press Room continued “Using CRISPR ”

Continued from page 6 osomes from healthy human cells and groups derived from breast cancer cells. The system consistently differentiated the cancer -related exosomes from those derived from healthy cells, showing it could be useful as a cancer diagnostic. The researchers say that this method has the potential to make cancer diagnosis and monitoring quicker and easier by analyzing blood samples.

Male Contraceptives

Continued from page 9 tes of mice.After a 28-day exposure, the animals’sperm counts decreased by about 45%. Additionally, EF-4-117 bound much more strongly to the CDK2 pocket than the dye, making it the highest affinity inhibitor for this site reported to date. The researchers say that this work proves the potential of this inhibitor for future therapeutic applications.

“Urine-diverting Toilets

Continued from page 12 diverting version. The researchers also calculated the maximum emissions for different viruses from a single flush. For example, they estimated that up to 390 million and 67 million genome copies of norovirus could be emitted from traditional and urinediverting toilets, respectively. These levels are within the range of an infectious dose; however, the researchers state that it’s unlikely a person would be exposed to all of the particles because some would probably evaporate, settle onto surfaces or be inactivated by handwashing. The next step is to determine a person’s risk of contracting these and other diseases from toilet flushing, the researchers say.
