Breaking the code: How is a mother's immunity transferred to her baby?

One of the most successful interventions in reducing infectious disease worldwide, vaccination still has limited effectiveness in protecting one group of patients—newborn infants. Now a study based at the Ragon Institute of MGH, MIT and Harvard has determined how a pregnant woman's vaccine-induced immunity is transferred to her child, which has implications for the development of more effective maternal vaccines. The report will be published in the June 27 issue of Cell and is receiving early online release.

Common conditions keep many patients out of knee cartilage research studies

Some of the most common traits among patients with cartilage issues in the knee are excluding them from participating in clinical trials because the trial outcomes might not yield the optimum results for new methods of cartilage regeneration, according to a Penn Medicine study published in Regenerative Medicine. Researchers testing the new methods tend to only include the patients most likely to succeed with the fewest complications, but if some of these trials could be safely opened up to different kinds of patients—such as those older than 55 or younger than 18, or those who knee joints don't align perfectly—the results could be much more robust and reflective of the patient population being treated. In the team's paper, they also highlighted therapies that hold special promise for the excluded populations, such as the use of "scaffolding" to promote cartilage growth.

Prostate cancer researchers find molecular switch to prolong survival

Wilmot Cancer Institute scientists believe they have figured out why a commonly used drug to treat late-stage prostate cancer often stops working after four or five months and appears to have a dual function that later turns the cancer into a relentless aggressor.

The Wikipedia gender gap

Wikipedia is one of the most successful online communities in history, yet it struggles to attract and retain editors who are women—another example of the gender gap online. In a recent University of Washington study, researchers interviewed women "Wikipedians" to examine the lack of female and non-binary editors in Wikipedia. The team identified a common theme: safety.
