Study specifies chemical pathway for ions through the cell membrane

Life ultimately depends on the traffic of tiny charged particles through porous proteins studding the membrane surrounding every cell. In research published in Nature, scientists at The Rockefeller University have for the first time mapped a stepping-stone pathway of amino acids that these charged particles, or ions, follow across cell membranes.

Scientists image transfer of antibodies from mother's milk, to baby's gut

The transportation of antibodies from a mother to her newborn child is vital for the development of that child's nascent immune system. Those antibodies, donated by transfer across the placenta before birth or via breast milk after birth, help shape a baby's response to foreign pathogens and may influence the later occurrence of autoimmune diseases.

New tool for early diagnosis of breast cancer

Scientists from Finland, Germany and the ESRF have developed a new X-ray technique for the early detection of breast cancer. This allows a 3D visualization of the breast with a high spatial resolution and is extremely sensitive to alterations in the tissue, such as those generated by cancer. This technique could be used in the next years in hospitals. It may help doctors to detect tumours with greater precision than is possible using current X-ray mammography.
