Finding the cells that put our brain to sleep and more — today's web signal.
As technology continues to advance at a rapid pace, we're seeing significant developments in fields ranging from neuroscience to cybersecurity and software updates. Researchers have made a breakthrough in understanding the brain's sleep mechanisms, identifying specific cells that play a crucial role in putting our brains to sleep. Meanwhile, concerns over cybersecurity are mounting, as a US government website was found to have used a Chinese model flagged as "malicious" by the FBI, highlighting the ongoing risks and challenges in this area.
In other news, tech administrators are being warned that the clock is ticking on Microsoft Edge's IE Mode, which is set to expire and may require significant updates to ensure compatibility. On a more forward-looking note, entrepreneur Jeff Lawson, co-founder of Inertia, is betting big on fusion technology, which will be showcased at TechCrunch Disrupt 2026. As these stories demonstrate, the intersection of technology, science, and innovation is constantly evolving, with new breakthroughs, challenges, and opportunities emerging every day.
