Short Report 

Weak Electromagnetic Fields, Cryptochromes and ROS

Rachel Sherrard, Natalie Morellini, Margaret Ahmad and colleagues show that weak repetitive magnetic field stimulation induces the production of Reactive Oxygen Species (ROS) in human cells through the action of cryptochromes, receptors implicated in magnetosensing. Read the accompanying Primer by Lukas Landler and David Keays.

Optimising Phage Cocktails

Bacteriophages can be useful antibacterial agents. Rosanna Wright, Michael Brockhurst and co-workers show that bacterial resistance to a focal phage can provide cross-resistance to unrelated phages that bind the same host receptor, and that this cross-resistance predicts how well combinations of phage will supress bacterial growth.

Natural Adaptive Therapy

Frédéric Thomas, Joel Brown, Robert Gatenby, Beata Ujvari and co-authors suggest that the pragmatic strategies employed in adaptive therapy may also be employed naturally by multicellular organisms to deal with the inevitable development of malignant cells during growth and maintenance of normal tissue.

Should Police Have Access to Genetic Genealogy Databases?

Christi Guerrini, Amy McGuire and co-authors present survey data which suggest that the public may not be particularly concerned about police access to personal genetic data that populate genealogical databases when the purpose is considered justified.
