Sea level much higher than assumed in most coastal hazard assessments

Nature reports that over 99% of coastal hazard studies mis-handle sea-level and land-elevation data, with about 90% using geoid-based sea level rather than local mean sea level (MSL) references like MDT. Meta-analyses show global coastal sea level is higher than geoid assumptions by about 0.27 m (EGM96) or 0.24 m (EGM2008), with larger gaps in the Global South (Indo-Pacific). Correct MDT-referencing increases exposed land by 31–37% and people by 48–68% under 1 m relative sea-level rise, especially in Southeast Asia. The study calls for re-evaluation, better data practices, and MDT use in assessments and IPCC reports.

Toxic combinations: when small signals add up to a security incident

Toxic combinations are security incidents formed when small signals—bot activity, misconfigurations, request anomalies, and exposed admin endpoints—converge to breach systems. Cloudflare surfaces these by inspecting the intersection of bot signals, sensitive paths (admin, debug, metrics, search), anomalies (unusual codes, geo shifts, rate evasion), and misconfigurations. In 24 hours, about 11% of hosts were susceptible (0.25% excluding WordPress). Examples: probing admin paths (/wp-admin, /admin), unauthenticated APIs with predictable IDs, leaked debug parameters, and exposed actuator or search endpoints. Mitigations: Zero Trust, IP allowlists, cloaked admin URLs, MFA, disable prod debug, API auth, secure monitoring endpoints; AI-assisted remediation in Security Insights.

Something is afoot in the land of Qwen

Alibaba’s Qwen project faces a leadership upheaval as Junyang Lin, the technical lead behind the open-weight Qwen models, resigns amid an internal reorganization that reportedly installed a Google Gemini alum to run Qwen. At an all-hands meeting, Alibaba CEO Wu Yongming acknowledged the shakeup, with several other core Qwen members also quitting (Binyuan Hui, Bowen Yu, Kaixin Li). Despite the turmoil, the Qwen 3.5 family is exceptionally strong, spanning models from Qwen3.5-397B-A17B (807GB) to smaller siblings: 122B, 35B, 27B, 9B, 4B, 2B, 0.8B, including a 2B multi-modal ~4.57GB (quantized 1.27GB). The future remains uncertain.

A Visual Guide to DNA Sequencing

Five pivotal DNA-sequencing methods are highlighted: Sanger’s chain-termination method (1977) and the early Maxam–Gilbert approach; Pyrosequencing (454) as the first commercial NGS; Illumina’s sequencing-by-synthesis producing massive short reads; PacBio’s SMRT single-molecule long reads; Oxford Nanopore’s nanopore sequencing for very long reads. The piece links the Human Genome Project’s cost collapse (from billions to ~$500 per genome) to these innovations, notes Illumina’s dominance and PacBio/Nanopore complementary roles, and mentions new, cheaper approaches and broad applications in medicine and archaeology.

Medical journal says the case reports it has published for 25 years are fiction

Canadian Paediatrics & Child Health corrected 138 CPSP case reports since 2000 to note they are fictional teaching cases, prompted by a New Yorker piece about the 2010 “Baby boy blue” case alleged to show opioid exposure via breast milk. Earlier cases, including the Lancet 2006 report and two now-retracted Canadian publications, are now questioned. The journal largely failed to label fiction; going forward, each clinical vignette will be described as fictional to protect confidentiality and preserve scientific integrity.

Libre Solar – Open Hardware for Renewable Energy

The Libre Solar Project offers hardware and software for renewable energy systems, including flexible MPPT/PWM solar charge controllers and Li-ion battery management systems. It provides Open Educational Resources on DC energy components and a collaborative forum to build renewable-energy components, with contact/impressum details.

The one science reform we can all agree on, but we're too cowardly to do

Adam Mastroianni argues the only science reform we can all agree on is to end for-profit scientific publishers. The current system pays researchers to do science, then pays publishers to publish it, while universities skim taxpayer funds and journals gatekeep access. Editors and peer reviewers work for free; publishers profit (often ~40%). SciHub, Aaron Swartz, and access crises show the system’s flaws. Pledges to publish only in non-profit or open journals have collapsed under collective-action problems. The fix: every government grant should bar funded research from for-profit journals; fund nonprofits and open models instead, ending the scam.

"It Turns Out"

James Somers analyzes the phrase “it turns out” and how writers like Paul Graham use it to imply discovery and neutrality. He argues it’s a lazy, writerly shortcut that disarms readers by framing an assertion as a dispassionate, hard-won finding, easing transitions from X to Y. He illustrates with examples of everyday scenarios (a deli, a movie twist) and Cambridge vs. New York, noting the phrase signals behind-the-scenes work. In mathematics, it marks results derived from prior work; it can be deceptive, but isn’t inherently misleading—readers should beware lazy usage.

Greg Knauss Is Losing Himself

Greg Knauss argues that AI and the ease of building apps threaten traditional programming, prompting him to augment his work with Claude Code and push for more personality and polish in Acorn. He reflects on the tension between making things and the ease of creation, remains hopeful, and asserts that discipline, vision, and the ability to ship—not just coding skill—will determine success.

The JVG algorithm could break RSA-2048 encryption with fewer than 5k qubits

AQTI announces the JVG algorithm, a hybrid quantum approach claiming RSA-2048 could be broken with fewer than 5,000 qubits, potentially in as little as 11 hours. If real, it accelerates quantum decryption and urgent PQC adoption, with 'harvest now, decrypt later' risks. The paper is a preprint awaiting independent validation. Regardless, it flags compressed crypto upgrade timelines: Google Chrome PQC, IBM's Quantum Safe roadmap to 2029, and Microsoft's 2033 target, pushing crypto-agile migration across sectors.

US Supreme Court's Republicans seized most dangerous power in constitutional law

Vox argues that the Supreme Court’s Republican majority in Mirabelli v. Bonta seized the power of substantive due process, a doctrine that lets judges create rights not explicit in the Constitution. The ruling requires public schools to disclose a student’s gender identity to parents, raising privacy and religious-liberty concerns and potentially forcing teachers to report on students’ identities. The piece portrays this as an unworkable, dangerous expansion of judicial power—the ‘One Ring’ cycle—risking chaos for public institutions, especially schools, and reviving Lochner/Roe-style critiques of substantive due process.
