Magnetic Nanoparticles Could Be Key To Effective Immunotherapy
Results of a study led by Johns Hopkins investigators suggests that a device composed of a magnetic column paired with custom-made magnetic nanoparticles may hold a key to bringing the body’s own immune system to better fight cancer and infection.

Neurons Constantly Rewrite Their DNA
Johns Hopkins scientists have discovered that neurons are risk takers: They use minor “DNA surgeries” to toggle their activity levels all day, every day.

MRI Based On A Sugar Molecule Can Tell Cancerous From Noncancerous Cells
Imaging tests can detect tumors, but figuring out whether a growth is or isn’t cancer usually requires a biopsy. Now results of a Johns Hopkins study suggest that MRI could one day make biopsies more effective or even replace them altogether by noninvasively detecting telltale sugar molecules shed by the outer membranes of cancerous cells.

‘Crispr’ Science: Newer Genome Editing Tool Shows Promise in Engineering Human Stem Cells
A powerful “genome editing” technology known as CRISPR has been used by researchers since 2012 to trim, disrupt, replace or add to sequences of an organism’s DNA. Now, scientists at have shown that the system also alters human stem cells.
