The world is experiencing a revolution in bioscience and biotechnology, which is now accelerating due to the convergence of AI with the life sciences.

These advances offer tremendous potential societal benefits but they also pose significant risks. www.lefigaro.fr/en/world/art...

91% support capping U.S. & Russian nukes—only 79% like apple pie.

@nti.org's “Keep a Cap on Nukes” campaign took over DC to highlight Trump's long-held view that nuclear weapons must be reined in.

The last remaining nuclear arms control treaty between the U.S. and Russia, New START, just expired.

For the first time in  several decades, there will be no limits on nuclear weapons and fewer tools to manage a crisis between the world’s largest nuclear powers.

NTI endorses the bipartisan Biosecurity Modernization and Innovation Act of 2026, led by Senators Tom Cotton (R-AR) and Amy Klobuchar (D-MN). This bill creates an important opportunity to incentivize a safe and secure U.S. bioeconomy through strengthened biosecurity policy.

If Congress doesn’t act, the last nuclear arms control treaty between the U.S. and Russia will expire. It would pointlessly wipe out decades of diplomacy, and could spark another arms race that makes the world less safe. This piece is worth the read.

In September 2025, Putin publicly proposed that the U.S. and Russia mutually observe New START limits for one additional year after the last remaining arms control treaty between the U.S. and Russia expires this February. The U.S. has yet to provide a formal public response to this proposal.

The upcoming expiration of the New Strategic Arms Reduction Treaty (New START) marks the removal of caps on U.S. and Russian long-range nuclear forces for the first time in decades. This risks increasing unpredictability and instability in the U.S.-Russia nuclear relationship at a complex time.
