Yale epidemiologist Harvey Risch, who has entertained a connection between Covid vaccines and "turbo cancer" and promoted ivermectin, says he'll chair the President's Cancer Panel. An epidemiologist who has speculated about whether there is a connection between Covid-19 vaccines and "turbo cancer" in young people, and works as chief epidemiologist at a company that sells ivermectin alongside reviews that claim it has efficacy as a cancer treatment, has been appointed by president Donald Trump to a key position overseeing the National Cancer Program. Harvey Risch, a professor emeritus of epidemiology at the Yale School of Public Health, announced his appointment as chair of the President's Cancer Panel on X earlier this month. Risch's profile page on the Yale website has also been updated to read "In November 2025, President Trump appointed Dr. Risch to Chair the President's Cancer panel." No formal announcement was made by the president or the White House, and the Cancer Panel website's list of current members does not include Risch.

Sen. Jim Risch, R-Idaho, says the United States is considering a "suite of options" in response to Iran's alleged responsibility for drone attack on Saudi Arabia's oil fields. "We have a commander-in-chief and he has said he does not want war with Iran and the Saudi Arabians have said the same thing," Risch said on "The Story with Martha MacCallum Wednesday. "The unfortunate part of all of this is Iran continues to push the envelope." U.S. Secretary of State Mike Pompeo on Wednesday doubled down on accusations Iran is responsible for the weekend bombing on Saudi Arabia's oil facilities, telling reporters that the strike was "an act of war." Earlier President Trump tweeted that he had ordered Treasury Secretary Steven Mnuchin to "substantially increase sanctions" on Iran. Risch said the Iranians are "notorious for making bad judgments" and said that's what is happening with the current situation. "[Trump] doesn't want war with Iran.

Three approaches to symbolic integration in the 1960's are described. The first, from artificial intelligence, led to Slagle's SAINT and to a large degree to Moses' SIN. The second, from algebraic manipulation, led to Manove's implementation and to Horowitz' and Tobey's reexamination of the Hermite algorithm for integrating rational functions. The third, from mathematics, led to Richardson's proof of the unsolvability of the problem for a class of functions and for Risch's decision procedure for the elementary functions. Generalizations of Risch's algorithm to a class of special functions and programs for solving differential equations and for finding the definite integral are also described.
