CHIME hydrogen result reaches peer-reviewed publication
A CHIME paper published in The Astrophysical Journal on September 28 reports a distant hydrogen signal detected from the telescope’s own radio data. Earlier CHIME work needed comparison with galaxy maps from other instruments to bring out the faint signal. The preprint appeared in 2025, so this week’s development is the peer-reviewed publication of that method and result, which could support later studies of cosmic expansion.
China starts interest subsidies for first-home mortgages
China will begin subsidising interest on eligible first-home mortgages in October. The support equals one percentage point a year on the loan principal and can last up to five years. The home must be no larger than 120 square metres and cost no more than 1.5 million yuan. The targeted measure aims to support weak housing demand, but does not cover every mortgage.
Cloudflare adds WebMCP tools to Kitesurf browser
Cloudflare added WebMCP support to Kitesurf, its browser for AI agents. On sites that expose compatible tools, an agent can invoke a function directly instead of navigating only by simulated clicks. Cloudflare is showing the feature in a public playground. The update expands a way to interact with supported sites; it does not establish that Kitesurf can complete every browser task or that all sites expose useful tools.
Clovis hunters sharpened spear points longer than their successors
A September 28 University of Mississippi announcement compares stone spear points from two successive Ice Age traditions in the Tennessee River Valley. Clovis points show more extensive resharpening, while Cumberland points were often discarded with usable stone remaining. An independently written Anthropology.net account identifies the same contrast. The researchers link it to changing knowledge of local stone sources, but the artifacts reveal patterns of use rather than any individual hunter’s motives.
Dakhla tomb pairs a Greek lament with protective hieroglyphs
A roughly 1,700-year-old tomb excavated in Egypt’s Dakhla Oasis bears a 19-line Greek lament and hieroglyphic spells intended to protect the dead. Live Science and Archaeology Magazine report the same structure, a man named Pisechtes, and a coin from Constantine’s reign. An independent scholar interviewed by Live Science also examined the poem. Archaeologists suggest the tomb may have been reused later; the reports do not establish that human remains were found inside.
Energy prices lift Belgium’s September inflation to 4.69%
Belgian consumer prices were 4.69% higher in September than a year earlier, up from 3.97% in August. Statbel identified energy as the main driver: higher diesel, natural gas and electricity prices lifted the overall rate. The index rose 0.39% from the previous month. The reading shows renewed pressure on household prices, though it does not mean every category became dearer at the same pace.
Estonia blames Russian security services for Milrem arson
Estonia’s security service attributed the August arson at a Tallinn building used by defence supplier Milrem Robotics to Russian security services. Three suspects detained in Latvia have been transferred to Estonia, and Tallinn plans to summon Russia’s chargé d’affaires. Moscow rejects the accusation. The new development is Estonia’s formal attribution, not the fire itself; the public account does not establish a court finding against Russia.
EU approves €60 million for Cabo Verde’s coast guard capacity
The EU Council approved a second €60 million assistance measure for Cabo Verde, focused on maritime security and the coast guard. The decision raises support under the European Peace Facility to €75 million in total. It funds capacity, training and logistics; no ship delivery or new patrol was announced. The fresh step is the adoption of the measure, with implementation still ahead.
Fed’s Cook warns AI investment could spread price pressure
Federal Reserve governor Lisa Cook warned that data-centre construction may raise demand for electricity and building labour used across the economy. She distinguished those pressures from price rises confined to AI chips and software, which monetary policy cannot target neatly. Cook expects productivity benefits over the next few years, but said they may arrive too late to offset wider inflation pressure later in 2026. She did not assign all recent utility-price increases to AI.
Florida asks court to pause OpenAI model development
Florida’s attorney general has asked a court to temporarily halt development of new ChatGPT models until outside reviewers approve safety safeguards. The request is part of an existing lawsuit and also seeks restrictions on minors’ access and how the chatbot is presented. No injunction has been granted; the immediate change is a proposed interim remedy, not a ruling on Florida’s allegations.
