SK Hynix raised $26.5 billion by selling 177.9 million American depositary shares at $149 each, surpassing Alibaba’s 2014 offering as the largest U.S. IPO by a foreign company. The ADSs represent one-tenth of an ordinary share and are scheduled to begin regular Nasdaq trading under SKHY on July 13.
The company’s prospectus says the proceeds will support a fabrication plant in South Korea, an advanced-packaging facility, and extreme-ultraviolet lithography equipment.

Trade Records Map Possible Routes for European Chips Into Russian Drones
Kharon identified two possible supply routes in which STMicroelectronics STM32 microcontrollers move through a distributor and Chinese drone-component manufacturers connected by sales or sanctions records to Russian buyers. The records do not establish the route of any particular chip recovered from a Russian weapon, and Kharon found no evidence that STMicroelectronics violated sanctions or export controls.

Microsoft Reports a 25% Annual Increase in Total Emissions
Microsoft’s 2026 sustainability report says its combined Scope 1, 2, and 3 emissions increased 25% in fiscal 2025. The company attributes the rise primarily to datacenter expansion and its decision to stop using non-additional, unbundled renewable-energy certificates while prioritizing projects that add new carbon-free power to grids.

CISA Says It Improvised an Incident Playbook During a Credentials Exposure
CISA’s postmortem says the agency lacked a prepared playbook when a contractor placed sensitive keys and credentials in a public GitHub repository in May, leaving staff to build one during the response. CISA says it revoked or rotated the credentials and found no evidence that customer or mission data was exposed, but did not quantify any resulting delay.

Reinforcement Learning Keeps a Quantum Processor Calibrated During Error Correction
Google researchers used quantum-error-detection events as a learning signal so an agent could adjust more than 1,000 control parameters while computation continued on the Willow superconducting processor. The Nature paper reports a 3.5-fold improvement in logical stability against injected drift when control and decoder steering were combined, although faster changes can exceed the system’s response time.

Oratomic Raises $300 Million for a Fault-Tolerant Quantum Computer
Neutral-atom quantum-computing startup Oratomic raised a $300 million Series A co-led by ARCH Venture Partners, Spark Capital, and Khosla Ventures. The Caltech-founded company says it will skip intermediate commercial systems and pursue a fault-tolerant machine requiring roughly 10,000 to 20,000 physical qubits, but it has not yet built the full-scale system.

GitHub Cuts Copilot Code-Review Cost by Retuning Its Repository Workflow
GitHub says rewriting Copilot code review’s instructions to begin with the pull-request diff and retrieve only evidence needed for targeted questions reduced average production review cost by roughly 20% without triggering its quality-blocking signals. The company did not publish the underlying benchmark data and found that the same strategy did not produce the same gain in the broader Copilot CLI workflow.

GhostLock Exposes a 15-Year-Old Linux Kernel Stack Use-After-Free
Nebula Security disclosed GhostLock, CVE-2026-43499, an unprivileged local Linux kernel flaw introduced in version 2.6.39 and fixed in 7.1. The researchers turned the dangling stack pointer in the Requeue-PI path into a privilege-escalation and container-escape exploit in Google’s kernelCTF environment.

Relativity Breaks the Textbook Triple-Bond Model in Heavy Elements
Brown University chemists reported direct spectroscopic evidence that spin-orbit coupling blurs the usual distinction between sigma and pi bonds in carbon-bismuth molecules. Their Science study found a structure resembling one pi bond and two hybrid sigma-pi bonds rather than the textbook model of one sigma and two pi bonds.

A Browser Code Runner Adds Go Through WASI
Ata Kuyumcu describes adding Go to the dailyprog puzzle site by compiling the Yaegi interpreter to WASI, avoiding the asynchronous initialization and global-object constraints of the standard GOOS=js target inside a V8 isolate. The implementation uses a small host shim for WASI imports and creates a fresh instance for each run.
