Trump bought between $1 million and $5 million of Axon shares just before ICE announced a potential $220 million contract for Tasers and other police tech, a move that coincided with a stock spike and raised questions about conflicts of interest; the White House says Trump’s investments are managed by independent firms and not controlled by him.
President Trump bought between $1 million and $5 million of Axon stock on Feb. 10, weeks before ICE posted a notice seeking a $220 million, five-year Taser contract, prompting ethics experts to caution about potential conflicts of interest. Officials say there’s no evidence of wrongdoing and the procurement is still in process, while Axon’s growing federal footprint—already supplying DHS and offering cloud, evidence, and AI tools—could benefit from any expansion of ICE’s Tasers, potentially deepening ties between the company and federal law enforcement.
Johns Hopkins researchers report axons may be pearl-like strings rather than smooth tubes, a pattern seen in mouse, worm, and human neurons and persisting in normal tissue. The beads are about 250 nm with 70 nm connectors, influenced by membrane stiffness and cholesterol, and can speed or slow signal transmission. This challenges a century of textbook axon structure and is supported by advanced imaging and living-brain tissue studies, suggesting membrane physics plays a key role in brain signaling.
Recent research challenges the long-held view that unmyelinated axons are smooth tubes by revealing a natural pearl-and-connector pattern that influences signal speed, with membrane mechanics and activity-induced shape changes playing key roles in neural timing and plasticity.
Ring has resumed allowing police to request user footage through a partnership with Axon, reversing its previous restrictions and aiming to enhance neighborhood safety, while maintaining user control and privacy protections.
Researchers have observed nerve plasticity within the axon initial segment (AIS) in real-time, shedding light on the adaptability of axons. The study reveals that the number of sodium channels in the AIS can change rapidly, within an hour, through a process called endocytosis. This adaptability allows for fine-tuning of neural activity and is crucial for learning and memory. The research team used innovative techniques, including live imaging, to observe these changes and identify the molecular mechanisms behind them. This groundbreaking research provides unprecedented insight into the intricate processes of neuroplasticity.
