New York City released more than 170,000 pages of previously undisclosed records Tuesday showing officials were aware of serious contamination concerns around Ground Zero following the 9/11 attacks, even as New Yorkers were publicly reassured about air safety.
The documents show asbestos was found nearly everywhere city inspectors tested around Ground Zero, among other evidence of hazardous conditions in Lower Manhattan. Some records indicate contamination persisted long after the immediate disaster, including asbestos detected above acceptable levels at a nearby building roughly a year later.
The disclosure comes as health consequences continue 25 years later. More than 140,000 responders and survivors are enrolled in the federal World Trade Center Health Program, which provides monitoring and treatment for 9/11-related illnesses including cancers and respiratory diseases. Tens of thousands of members have conditions certified as related to their exposure.

An AI-designed drug showed early signs of affecting biological aging in a small human trial. Rentosertib, developed by Insilico Medicine primarily to treat chronic lung disease, reduced several measures associated with aging during a 12-week study involving 42 participants.
Researchers evaluated six different "aging clocks," which combine biomarkers and other health measurements to estimate how quickly the body is aging. Patients receiving rentosertib showed declines across all six measures, while biological age generally increased or remained unchanged among those receiving a placebo or no treatment.
While the findings suggest rentosertib may influence biological processes associated with aging, they don't yet show that the drug extends lifespan or slows aging itself. Aging clocks remain an evolving field, and no universally accepted measure of biological age exists. Larger and longer trials will be needed to determine whether the changes translate into meaningful health benefits.

Canada's retaliatory tariffs on roughly $20 billion of U.S. goods took effect Tuesday, two weeks after failed trade negotiations prompted Washington to impose matching duties on Canadian products. The new tariffs range from 15% to 50%, extending a trade dispute between two countries that exchanged more than $700 billion in goods last year.
Products facing 50% tariffs include American milk, perfume, video game consoles, golf clubs, clothing, steel and aluminum. Cheese and some household appliances face 25% duties, while some industrial equipment faces 15%. Canada removed planned tariffs on some U.S. seafood following concerns about the closely integrated cross-border supply chain.
The U.S. responded hours later by announcing bans on imports of some Canadian autos, dairy products, alcohol and motorcycles beginning Sept. 29. The White House said the measures directly retaliate against Canada's new tariffs. A threatened 50% tariff on Canadian cars and trucks starting Jan. 1 also remains on the table.
