In the fight against cancer, knowing the enemy’s exact identity is crucial for diagnosis and treatment, especially in metastatic cancers, those that spread between organs and tissues. Now chemists led by professor Vincent Rotello of the Chemistry Department have developed a rapid, sensitive way to detect microscopic levels of many different metastatic cell types in living tissue. Findings appear in the current issue of the journal ACS Nano.

Concerns over mosquito-borne illnesses prompt cancellation of evening outdoor activities

Campus officials have cancelled nighttime outdoor activities as a precautionary measure against mosquito-borne illnesses such as eastern equine encephalitis (EEE). Departments, programs and students are being advised to reschedule outside events or, if possible, to move them indoors.
 
The dusk-to-dawn ban (approximately 6:30 p.m. to 6 a.m.) on outside events is in accordance with recommendations from the state Department of Public Health for towns designated at high or critical risk for EEE.
