Our brain doesn’t just feel, it decides how much to feel. Researchers discovered a feedback loop that adjusts how sensitive we are to touch, depending on context. This dynamic brain circuit could help explain sensory fluctuations and traits linked to autism.
The cerebral cortex handles incoming sensory input through an intricate web of neural connections. But how exactly does the brain fine-tune these signals to shape what we perceive? Researchers at the University of Geneva (UNIGE) have uncovered a mechanism where specific projections from the thalamus influence the excitability of certain neurons.

Zoom and Xerox have addressed critical security flaws in Zoom Clients for Windows and FreeFlow Core that could allow privilege escalation and remote code execution.
The vulnerability impacting Zoom Clients for Windows, tracked as CVE-2025–49457 (CVSS score: 9.6), relates to a case of an untrusted search path that could pave the way for privilege escalation.
“Untrusted search path in certain Zoom Clients for Windows may allow an unauthenticated user to conduct an escalation of privilege via network access,” Zoom said in a security bulletin on Tuesday.
