The study sheds light on mechanisms that could help humans recover from hearing loss.

A new study from USC Stem Cell scientists reveals how certain animals, such as zebrafish and lizards, can regenerate their hearing by reactivating dormant gene regulators.

The discovery provides insight into the mechanisms that could one day help humans recover from hearing loss and balance disorders.

Led by Tuo Shi, Ksenia Gnedeva, and Gage Crump from the Keck School of Medicine of USC, the research focuses on the inner ear’s two critical cell types: sensory cells, which detect sound, and supporting cells, which provide structural and functional support.

Conversely, proprietary LLMs typically offer robust security features but still pose data privacy and control risks. Using these models involves sharing sensitive data with a third-party provider, which could lead to regulatory penalties if a breach occurs.

LLMs also lack transparency regarding their training data and how datasets are formed. Be mindful of potential bias and fairness issues and consider a human-in-the-loop approach, where specialists review and manage the model’s output.

LLMs are most effective when used to streamline complex processes and drive innovation. To leverage these models responsibly, prioritize data governance—especially in highly regulated industries.

On October 1, 2024, the Food and Drug Administration (FDA) marked a major milestone in medical device cybersecurity enforcement. This marks one year since the retracted Refuse to Accept (RTA) policy and the full implementation of the Protecting and Transforming Cyber Healthcare (PATCH) Act amendment to the Food, Drug & Cosmetic Act (FD&C). The FDA’s new requirements represent a fundamental shift in the regulatory landscape for medical device manufacturers (MDMs), as cybersecurity is now a non-negotiable element of device development and compliance.

The timing is not coincidental. In 2023, the FDA issued its final guidance entitled “Cybersecurity in Medical Devices: Quality System Considerations and Content of Premarket Submissions.” This outlined the detailed cybersecurity requirements and considerations that MDMs must address in their submissions, highlighting the security measures in place to gain regulatory approval. With these requirements, the FDA is taking a hard stance: Cybersecurity is a core consideration, with compliance being systematically enforced.

Kaunas University of Technology (KTU), Lithuania researchers, and scientists from Japan have developed a unique nanolaser. Although the dimensions of this laser are so small that its structure can only be seen through a powerful microscope, its potential is vast. With applications in early medical diagnostics, data communication, and security technologies, this invention could also become a key tool for the study of light and matter interactions.

Depending on the application, lasers differ in the way light is amplified and produced, which determines the color of the radiation and the quality of the laser beam.

“Nanolasers are lasers that use structures a million times smaller than a millimeter to generate and amplify light, and the laser radiation is generated in an extremely tiny volume of material,” says Dr. Mindaugas Juodėnas, one of the authors of the invention.

The sun continues its hurling out solar flares. On Sunday, it hurled out an X-class solar flare, the strongest type of solar flare, signalling its dynamic nature. The dramatic eruption originated from sunspot region 3,912, peaking at 4:06 AM. EST (0906 GMT) on December 8. Accompanying the flare was a coronal mass ejection (CME), a massive outpouring of magnetic fields and plasma from the sun’s atmosphere.

While CMEs, also known as solar storms, can cause geomagnetic disturbances and spark vibrant auroras when they interact with Earth’s magnetosphere, experts predict only mild effects from this event. According to Space Weather physicist Tamitha Skov, Earth may experience a glancing blow from the CME.

“The solar storm launched will graze Earth to the west. Sadly, the coming fast solar wind streams might deflect the structure even further to the west. Expect only mild impacts by midday December 11,” Skov shared in a post on X.
