Proposed EPA Rule Could Evaluate Toxic Chemical Risks with Less Rigor, Limit State Powers

The Trump administration’s EPA has proposed a rule that could weaken safety reviews for toxic chemicals and prevent states from enacting their own restrictions, according to reports. Critics warn this may increase health risks for consumers and workers exposed to hazardous substances.

Proposed Changes to Chemical Safety Reviews

The Environmental Protection Agency under the Trump administration has proposed a new rule that would significantly alter how some of the nation’s most toxic chemicals are evaluated for safety, according to reports from public health advocates and an EPA employee. The rule would affect substances including PFAS, formaldehyde, asbestos, and dioxins, which are known to pose serious health risks in consumer goods and workplaces.

Breakthrough Cryo-EM Strategy Enables High-Resolution Imaging of Small Cancer Proteins

Scientists have overcome a major limitation in cryo-electron microscopy by developing a novel fusion strategy that enables high-resolution structural determination of small proteins. The breakthrough method successfully resolved the structure of cancer-related kRasG12C at 3.7 Å resolution, clearly showing how inhibitor drug MRTX849 interacts with its target.

Overcoming Size Limitations in Structural Biology

Structural biologists have reportedly developed an innovative approach that extends the capabilities of cryo-electron microscopy to small protein targets previously considered too challenging for high-resolution analysis, according to recent research published in Scientific Reports. The new method addresses what sources indicate has been a fundamental limitation in the field—the difficulty of imaging proteins smaller than 50 kilodaltons (kDa) using single-particle cryo-EM techniques.

Voters in Colorado and Texas to Decide Divergent Tax Policy Measures This November

Colorado voters face two tax hike measures to fund universal school lunches, while Texas considers multiple constitutional amendments prohibiting new taxes. The divergent approaches reflect broader fiscal policy trends between states.

State Tax Policy Divergence on November Ballots

While national attention has focused on redistricting efforts, sources indicate voters in Colorado and Texas will decide significantly different tax policy measures this November that reflect broader fiscal trends. According to reports, Colorado’s Democrat-led legislature has referred two tax increase measures to voters, while Texas’s Republican-controlled government is proposing multiple new taxpayer protections.
