In Trump’s New Purge of Climate Language, Even “Resilience” Isn’t Safe
In his first hours back in the White House in January, President Donald Trump signed an executive order titled “Restoring Freedom of Speech and Ending Federal Censorship.” Yet it was immediately clear he was in fact imposing his own strict rules on language usage.In one executive order, he redefined “energy” to exclude solar and wind power.The term “climate change” was removed from federal website in Trump’s first term, and now “sustainability” and “resilience” have also disappeared.

To Avoid a Ukraine-Style Quid Pro Quo, Australia Needs to Work with the U.S. on Critical Minerals
With Donald Trump back in the White House, Washington is operating under a hard-nosed, transactional framework in which immediate returns rather than shared values measure alliances. For Australia, this signals a need to rethink its approach to the US relationship. A key step would be to work with the United States in the extraction and processing of Australian critical minerals.

On Hurricanes and Hoaxes: A Case for Finding Common Ground
Conspiracy theories offer an easy, emotionally satisfying answer to a complicated problem. Instead of facing the reality of climate change, or reckoning with their own complicity, people can choose a different story: that climate disasters are manipulated, that scientists are corrupt, and that the crisis is exaggerated for political gain.

Why a U.S. Minerals Deal with Ukraine Won’t Deter Russian Aggression
Research suggests that investments follow alliances. But markets do not care about agreements alone. They respond to other signals too, like explicit statements of support. These statements of support also help to reassure allies and deter rivals. Unless Trump changes how he operates on the international stage, the economics of the mineral deal will not help Ukraine’s security situation.

The Value of Ukraine’s Critical Minerals Is Overstated
In fact, Ukraine has no proven rare earths reserves—as distinct from deposits, which may or may not be economically recoverable. Its only established rare earths deposit, of unknown size or quality, is near Azov, a town currently under Russian control.

Research Drives Innovation in Gen-IV Reactor Safety and Efficiency
All U.S. nuclear reactors, which currently provide more than half of the nation’s carbon-free power, are first- or second-generation light water reactors. This means they use water as both a coolant and neutron moderator to control the nuclear reaction and produce useful electricity. Ut researchers pursue all kinds of reactor designs, and nuclear engineers at Argonne frame the future of nuclear design.

U.S. Cuts to Science and Technology Could Fast-Track China’s Tech Dominance
Is the United States now trying to lose the technology race with China? It certainly seems to be. The race is tight, and now the Trump administration is slashing funding for the three national institutions that have underpinned science and technology (S&T) and what advantage the US still has.

3 Questions: Exploring the Limits of Carbon Sequestration
Elevated CO2 levels can lead to a phenomenon known as the CO2 fertilization effect, where plants grow more and absorb greater amounts of carbon, providing a cooling effect. While this effect has the potential to be a natural climate change mitigator, the extent of how much carbon plants can continue to absorb remains uncertain. MIT assistant professor César Terrer discusses pioneering volcano research to track carbon dynamics in tropical forests.
