NASA links nanobacteria to kidney stones and other diseases

... the group's research provides additional clues to understanding NB and its link to pathologic calcification-related diseases. "Hopefully, eradication or treatment of these diseases will be possible in the near future. We need more research and support to solve this puzzle, but we feel that we are close," adds Ci...

Researchers discover molecular mechanism that desensitizes us to cold

...we sense heat and cold and from that to expand our understanding of temperature regulation," said Dr. Logothetis. "Additionally, because the region of this receptor that interacts with PIP2 is found in many similar membrane proteins, we now have a new lead in investigating regulation of the many functions in which...
