6G research is moving from the theoretical to the practical as we speak. While there is no 6G standard as of yet, the need for experimental testing of new solutions and technol­ogies that will define 6G is growing by the hour. To rise to the challenge, the University of Oulu has been all the while building a state-of-the-art hub for exactly this type of test­ing. The University of Oulu’s highly sophisticated 6G Test Centre is a collection of facilities for researchers and developers to create prototypes and test solutions in the current and com­ing wireless environment. The 6GTC’s membership in the NATO DIANA network reinforces innovation in dual-use technologies.

A team of researchers at NYU Tandon School of Engineering has developed a novel method to detect hidden GPS tracking devices in vehicles, offering new hope to victims of technology-enabled domestic abuse. The research addresses a growing problem: abusers secretly placing GPS trackers in their partners' or ex-partners' vehicles to monitor their movements. Traditionally, detecting these devices has been difficult and expensive, leaving many victims vulnerable to continued surveillance.

A Cornell University researcher was close to finalizing a prototype of a new test that can detect any tick-borne disease until a stop-work order from the federal government in April.

A research project that explores new ways to ensure active-duty military personnel get adequate nutrition has been halted – with further implications for the nutritional needs of the aging and those suffering from chronic diseases.

To mark this year's Children's Safety Day on 10 June, the German Federal Institute for Risk Assessment (BfR) is drawing attention to the health risks of swallowed button cells with a new science comic. If the small, flat batteries pass through the oesophagus, complications are rarely to be expected - it is usually sufficient to wait for them to shed naturally under medical supervision. However, if the battery gets stuck in the oesophagus, parents must act quickly: Contact with the moist mucous membranes causes a current to flow. Hydroxide ions form at the interface between the button cell and the mucous membrane, which can lead to severe burns. "The more the battery is charged, the more serious the consequences," says Professor Matthias Greiner, Head of the Exposure Department at the BfR. "Lithium button cells are particularly problematic as they have a comparatively high electrical voltage." Large button cells (with a diameter of over 20 millimetres) pose an increased health risk as they are more likely to get stuck in the oesophagus.
