Scientists just teleported information using light

Quantum communication is edging closer to reality thanks to a breakthrough in teleporting information between photons from different quantum dots—one of the biggest challenges in building a quantum internet. By creating nearly identical semiconductor-based photon sources and using frequency converters to sync them, researchers successfully transferred quantum states across a fiber link, proving a key step toward long-distance, tamper-proof communication.

Miracle material’s hidden quantum power could transform future electronics

Researchers have directly observed Floquet effects in graphene for the first time, settling a long-running scientific debate. Their ultrafast light-based technique demonstrates that graphene’s electronic properties can be tuned almost instantaneously. This paves the way for custom-engineered quantum materials and new approaches in electronics and sensing.

Scientists uncover the brain’s hidden learning blocks

Princeton researchers found that the brain excels at learning because it reuses modular “cognitive blocks” across many tasks. Monkeys switching between visual categorization challenges revealed that the prefrontal cortex assembles these blocks like Legos to create new behaviors. This flexibility explains why humans learn quickly while AI models often forget old skills. The insights may help build better AI and new clinical treatments for impaired cognitive adaptability.

Social data puts user passwords at risk in unexpected ways

Many CISOs already assume that social media creates new openings for password guessing, but new research helps show what that risk looks like in practice. The findings reveal how much information can be reconstructed from public profiles and how that data influences the strength of user passwords. The study also examines how LLMs behave when asked to generate or evaluate passwords based on that same personal information. The research team from the University of Cagliari … More → The post Social data puts user passwords at risk in unexpected ways appeared first on Help Net Security.

New observational auditing framework takes aim at machine learning privacy leaks

Machine learning (ML) privacy concerns continue to surface, as audits show that models can reveal parts of the labels (the user’s choice, expressed preference, or the result of an action) used during training. A new research paper explores a different way to measure this risk, and the authors present findings that may change how companies test their models for leaks. Why standard audits have been hard to use Older privacy audits often relied on altering … More → The post New observational auditing framework takes aim at machine learning privacy leaks appeared first on Help Net Security.

Fragmented tooling slows vulnerability management

Security leaders know vulnerability backlogs are rising, but new data shows how quickly the gap between exposures and available resources is widening, according to a new report by Hackuity. Fragmented detection and slow remediation Organizations use a formalized approach to manage vulnerabilities, but their tooling remains fragmented. Respondents rely on an average of four detection tools, and cloud or container configuration audits are the most common at 85%. This mix suggests broad coverage, but it … More → The post Fragmented tooling slows vulnerability management appeared first on Help Net Security.
