Transplanting kidneys which have stones poses little risk to organ's viability

A recent study at Mayo Clinic found that transplanting kidneys with small stones does not significantly affect the kidney's function. The study followed 44 donor kidneys, of which 86% had stones smaller than 2mm, and reported a 97% graft survival rate after 26 months, comparable to national averages for living kidney donation.

Cure for common cold will need to wiggle to work, scientists say

Researchers at Purdue University found that the flexible structure of WIN compounds allows them to shimmy into the proteins forming the virus' outer shell and alter them. This could potentially stop the infection process. The team believes WIN compounds may be effective in stabilizing proteins, preventing the viral trap door from opening.
