Cheaters beware: ChatGPT maker releases AI detection tool
SAN FRANCISCO (AP) — The maker of ChatGPT is trying to curb its reputation as a freewheeling cheating machine with a new tool that helps teachers detect whether a student or an artificial intelligence wrote the assignment. The launch of OpenAI’s new AI text classifier comes after weeks of discussions at schools and universities over concerns that ChatGPT’s ability to write anything on command could encourage academic dishonesty and hinder learning. OpenAI warns that its new tool is not foolproof, and that the methods for detecting text written by AI are imperfect and can sometimes be wrong.

Difficulty measuring methane slows plans to cut emissions
NEW YORK (AP) — Satellites, drones and planes equipped with infrared cameras could become the backbone of a new federal policy to fine America’s biggest methane polluters. But the fledgling industry still has a long way to go before it can accurately measure emissions from methane polluters. The new national methane reduction plan, passed as part of the Lower Inflation Act, will allow the government to fine polluters for methane emissions based on measurements through 2024. This leaves little time to build a reliable system.

Boeing bids farewell to icon, delivers last 747 jumbo jet
SEATTLE (AP) — Boeing said goodbye to a sign Tuesday: It was delivering its last 747 jumbo jet.

Lawmakers aim to increase penalties for U.S. airline disruptions
WASHINGTON (AP) — Congress will revisit legislation covering the rights of airline passengers. Sens. Richard Blumenthal, D-Connecticut, and Edward Markey, D-Mass., said Tuesday they reintroduced bills to increase penalties when airlines hold or delay passengers and limit airline fees . Both ideas have failed in previous years, but senators say they have a good chance of succeeding this time because of anger over the Southwest Airlines fiasco in December. But they will face obstacles. Republicans have yet to support the measures. Airlines have previously successfully lobbied Congress against proposals to limit or regulate the fees they charge customers for services such as checked bags.

Alaska gold, copper mines blocked over environmental concerns
JUNO, Alaska (AP) — Federal environmental regulators have blocked a proposed Alaska mine that proponents have hailed as the world’s most important untapped copper and gold resource. The U.S. Environmental Protection Agency took unusually strong steps Tuesday. It is concerned about the mine’s environmental impact on the rich aquatic ecosystem that supports the world’s largest sockeye salmon fishery. Alaska Native tribes and environmentalists celebrate Pebble Mine veto. But John Shively, chief executive of Pebble Limited Partnership, called the move “illegal” and said a lawsuit was likely. In 2010, tribes in the Bristol Bay area asked the EPA to protect the area under the federal Clean Water Act.
