Hijacked servers rewrote their exit policies to funnel port-22 traffic to 12 interceptors and favour unencrypted mail. The root cause was ordinary host compromise, not a flaw in Tor's protocol.
A script error in an April 2025 HSM key ceremony left eight trusted intermediate CAs with private keys under 256. The incident exposes weaknesses in CA oversight, CRL handling and the slow tail of revocation.
A half-millimetre gel film with a single layer of optogenetic muscle cells per fin swims and steers through a maze. The design cuts the muscle needed, though the robot is still slow and lab-bound.
Motors draw nearly a third of US power, and few run on variable frequency drives. Slowing them to match demand frees capacity on the demand side, which grid hardware cannot do.
Two use-after-free bugs in PHP's engine, rated CVSS 9.2, survived a 2024 audit. An AI-assisted effort then turned them into working exploits, with consequences for how legacy code gets maintained.
POSTECH's polarization-multiplexed silicon nitride metalens and liquid-crystal cell switch between two foci in about 250 ms. The paired foci give 1.2 mm of axial coverage with no moving optics.
NTU Singapore's bias-free device swaps oxygen evolution for hydrazine oxidation, giving 25 mA/cm² and 72 hours of stable operation in seawater. The catch is that it needs the pollutant to work.
