Medicine Nobel honours the tools that let light control nerve cells

The 2026 medicine Nobel recognises Karl Deisseroth, Peter Hegemann and Georg Nagel for discoveries that turned light into a precise tool for testing what nerve cells do.

Schematic of a closed channel without light and an open channel under blue light, with positive ions entering through the open channel. Below, only the highlighted engineered neuron carries the light-sensitive channels. The experiment changes selected cells and measures the consequence.
Blue light opens channelrhodopsin-2 in cells engineered to express it, allowing positive ions to flow and making electrical activation possible. Choosing the cells and timing the light lets an experiment test causal effects. Recorded response data are not supplied.

Supreme Court opens its term with a test of local climate lawsuits

The Supreme Court's October 5 hearing concerns whether federal law blocks Boulder's climate-damage claims against ExxonMobil and Suncor—and whether the justices can review the case at this stage.

A branching schematic separates two legal questions. If the Supreme Court cannot review now, it does not reach the federal merits. If it can, it considers whether federal law blocks the claims. Claims that survive still require proof; adverse rulings may close legal routes. Neither question calculates a damages award. Simplified possibilities, not predicted outcomes.
Two legal questions stand between the present appeal and any later damages decision. Surviving a federal-law challenge would still leave claims to prove. Branches simplify the issues; they do not predict the ruling or show every possible outcome.

Brazil · A lead without a majority

Brazil's presidency goes to an October 25 runoff between Flávio Bolsonaro and Lula

Flávio Bolsonaro led Lula by 47.03% to 45.16% in Brazil's near-complete first-round count; neither secured the majority needed to avoid an October 25 runoff.

Original chart on a common zero-to-100% scale: Flávio Bolsonaro 47.03%, Lula 45.16%, other candidates 7.81%. Both finalists fall below the 50% reference; first-round victory requires more than half of valid votes.
First-round valid-vote shares, with 99.99% tallied in the TSE's October 5 snapshot. The remainder, 7.81%, is calculated from the rounded shares. It represents votes for other candidates, not a forecast of transfers in the runoff.

ChatGPT plans visual ads during image generation, starting with a US test

OpenAI will test clearly labelled visual ads during ChatGPT image generation later in October, beginning in the United States with selected advertisers.

Current chat context reaches ad selection. An open switch blocks past context. The generated image and the paid placement appear as separate outputs, with no line between them. This depicts OpenAI's stated policy.
Disabling personalisation removes past conversations and advertising history from ad selection; the current chat can still inform it. OpenAI says the planned paid placement stays separate from the generated image.
