Although there are no existing biomarkers for Parkinson’s, diagnosis may just be a phone call away.

In my opinion, there are waaayyy too many cell phones in schools these days. Ringing, texting, gaming…all of these are annoyances that disturb class and distract students’ attention. However, students at Johns Hopkins have redeemed themselves and renewed my confidence that undergrads can actually utilize cell phones responsibly.
Johns Hopkins biomedical engineering undergraduates have developed a noninvasive way to identify patients suffering from anemia hoping to save thousands of women and children from this dangerous blood disorder in developing nations. The device, HemoGlobe, is designed to convert the existing cell phones of health workers into a “prick-free” system for detecting and reporting anemia at the community level.
Brown University researchers have created a reliable and fast flu-detection test that can be carried in a first-aid kit. The novel prototype device isolates influenza RNA using a combination of magnetics and microfluidics, then amplifies and detects probes bound to the RNA. The technology could lead to real-time tracking of influenza. Results are published in the Journal of Molecular Diagnostics.
Scientists at the University of Pennsylvania are printing blood vessel networks out of sugar.
Toxic chemicals wreak havoc on cells, damaging DNA and other critical molecules. A new study from researchers at MIT and the University at Albany reveals how a molecular emergency-response system shifts the cell into damage-control mode and helps it survive such attacks by rapidly producing proteins that counteract the harm.
Peter Dedon, a professor of biological engineering at MIT, and colleagues had previously shown that cells treated with poisons such as arsenic alter their chemical modification of molecules known as transfer RNA (tRNA), which deliver protein building blocks within a cell. In their new paper, appearing in the July 3 issue of Nature Communications, the research team delved into how these modifications help cells survive.
