Several malicious packages on NuGet have sabotage payloads scheduled to activate in 2027 and 2028, targeting database implementations and Siemens S7 industrial control devices.

The embedded malicious code uses a probabilistic trigger, so it may or may not activate depending on a set of parameters on the infected device.

NuGet is an open-source package manager and software distribution system, enabling developers to download and include ready-to-run. NET libraries for their projects.

A palm-sized laser from Stuttgart hits 80% efficiency, doubling current tech and redefining ultrafast optics.

Tissue-resident memory T cells that express TCF1 or ID3 exhibit stem-like properties and regulate memory heterogeneity and recall.

To make things better, first prove how good they can possibly be.

We propose and demonstrate a high-performance asymmetrical multimode interference splitter on X-cut lithium niobate on insulator (LNOI) with an ultra-compact size of 5.8 μm × (26.4–35.6) μm. A rectangle with a small region is removed from the upper left corner of the multimode interference (MMI) coupler to achieve a variable splitting ratio. Here, we design and characterize MMIs in six different distribution ratios ranging from 50:50 to 95:5 on a 600 nm thick LNOI. Based on the cascade structure, the linear fitting method accurately shows the device loss (~0.1–0.9 dB). Our fabricated devices demonstrate robustness across a 30 nm optical bandwidth (1535–1565 nm). In addition, we numerically simulate the Z-cut LNOI, showing that the structure corresponding to the TM mode can also achieve a good variable splitting ratio.

The study has resolved a long-standing cosmic puzzle and provided strong evidence for the existence of widespread magnetic fields — likely relics from the early Universe.
