As Seen in State of the Union—Utilities Bend Under Too Much Demand The rise from data centers is unprecedented.

The rising demand from data centers is greater than the utility industry has seen in anyone’s career. What is unraveling under this pressure, and what new opportunities are emerging from the crisis? UCS’s Mike Jacobs breaks it down in his blog:

A social media graphic shows four people standing on a hill overlooking a densely built city partially covered in smoke or haze. Below the photo, on a black background, a large quote reads: “This illegal war will not bring safety or security to the American people or its allies. Congress must exercise its responsibilities to rein in President Trump and his administration.” Beneath the quote is a small headshot of Tara Drozdenko, identified as Director of the Global Security Program, along with the Union of Concerned Scientists logo and a 2026 copyright notice.

President Trump’s illegal war of aggression against Iran, in cooperation with Israel, actively undermines global security, raises the long-term danger of nuclear proliferation, and risks dragging the US into another dangerous and protracted conflict.

"Congress should require an independent review of the Trump administration’s allegations, and the administration, with support from the CTBTO and independent scientific experts, should engage in talks with China and Russia on voluntary confidence-building transparency measures."

Without the New START treaty, do you think an arms race is on the horizon?

'Mr. Trump repeated a claim the administration has made before: that prescription drug prices have been reduced by as much as 600 percent. On its face, a 600 percent reduction in drug prices would require a pharmaceutical company to pay you five times over to take a medication."

The United States and Russia Can’t Give Up on Arms Control Now The United States and Russia have a 50-year history of arms control agreements. That shouldn't end with the expiration of the New START treaty.

"Arms control is far from a perfect solution to the nuclear threat. … But arms control can, as a starting point, reduce the likelihood of nuclear war and provide some measure of stability and predictability."

Every Day, Nukes Are Riding Right Past People Like You Every day, nuclear weapons are transported in trucks riding along interstates that connect communities across the United States.

"As part of a new plan to restart large-scale production of plutonium pits for the first time since the Cold War, the NNSA plans to ship nuclear cores across the length of US interstates without clearly informing residents."

What Does the New Partnership Between Canada and China Tell Us about Future Chinese Foreign Policy? If more countries join Canada in breaking from the US government, China could alter its policies and possibly help end the war in Ukraine.

In his blog, UCS’s @gkucs.bsky.social analyzes the recent announcement by Canadian Prime Minister Mark Carney in Davos, and what it could mean for US hegemony if other "middle powers" pursue their own strategic partnerships with China.

"If enough members of the European Union decide to join Carney in making an equally clear and irreversible break with the US government, Chinese leaders could become more willing to work with European governments to end the fighting in Ukraine."

Data Center Power Play Unmitigated data center growth puts the public at risk of higher utility bills and public health costs.

Russia says it has no specific contacts with US on expiring nuclear treaty Russia and the United States currently have no specific contacts regarding the imminent expiry of the New START nuclear arms control treaty, Russian Foreign Minister Sergei Lavrov said on Tuesday.

The Trump team is dropping the ball on New START, which limits deployments of nuclear weapons. Russia has offered an off ramp without negotations but the US isn't responding. This is a no-brainer, but Trump's ignorance and machismo are likely to result in the shredding of this important treaty.

The Nuclear Testing Moratorium Passes a Milestone The world has now gone the longest period of time since 1945 without an explosive nuclear test. Breaking this streak would be not only unnecessary but also unwise.

"While the date will go unnoticed by most, January 14, 2026, marks a milestone in world history. As of today, the world has gone eight years, four months, and 11 days without a nuclear test—the longest period since the Trinity test without a nuclear explosion."
