Nearly all school nurses participating in a national survey (96 percent) reported that staff at their school received training on handling severe allergic reactions to food. Over 80 percent asserted that their school had an emergency epinephrine auto-injector on hand to stop a potentially life-threatening allergic reaction. The study findings, published in the Annals of Allergy, Asthma and Immunology, also underscore the dire need for these policies, with over one-third of the school nurses reporting at least one severe allergic reaction to food at their school in the last academic year.

"Has this patient been drinking?" It's a critical question for neurosurgical nurses and other professionals when evaluating patients with traumatic brain injury (TBI). But some groups of TBI patients are less likely to be screened for alcohol use, including women and younger patients, reports a study in the March issue of the Journal of Neuroscience Nursing, official journal of the American Association of Neuroscience Nurses.

Bioreactors are used to produce different therapeutics in the biopharmaceutical and regenerative medicine industries. Drug development relies on small multi-well plates shaken around an orbital diameter, while production-scale bioreactors are agitated by stirring. These different methods yield different fluid dynamics. Researchers in the U.K. are starting to bridge this gap by applying analytical techniques for stirred bioreactors to the fluid dynamics of orbitally shaken bioreactors. They discuss their work in this week’s Physics of Fluids.

Drug therapies that target a specific molecule have changed the way patients are treated for cancer and greatly improved survival rates. However, some patients do not respond to these therapies because the drug is not reaching the tumor cells effectively. In a new study published in Scientific Reports, Moffitt Cancer Center researchers combined single-cell imaging of cancer cells in mice with mathematical modeling to determine which drug characteristics are the most important for efficient drug uptake.

Working together, Miller, Boehme, Vardeny and their colleagues have shown that an organic-based magnet can carry waves of quantum mechanical magnetization, called magnons, and convert those waves to electrical signals. It’s a breakthrough for the field of magnonics (electronic systems that use magnons instead of electrons) because magnons had previously been sent through inorganic materials that are more difficult to handle.
