| Chemical & Engineering News (C&EN) Verified
Key Insights The America250 commission is burying a time capsule filled with memorabilia from all 56 US states and territories in honor of the nation’s semiquincentennial. The artifacts include emerging technologies such as quantum computing and DNA data storage. Scientists needed to meticulously consider the materials of the capsule and its contents to ensure that it survives its journey to the future.

C&EN weekly chemistry news quiz, July 3

| Chemical & Engineering News (C&EN) Verified
A “masked acid” chemical additive has been found to speed up the breakdown of which popular biodegradable polymer? • PLA (polylactic acid) • PET (polyethylene terephthalate) • PVC (polyvinyl chloride) • HDPE (high-density polyethylene) Before the “masked acid” additive, what challenging conditions did polylactic acid (PLA) require for biodegradation?

Key Insights In a case that hinged on questions of executive branch control of independent agencies, the Supreme Court ruled in favor of the Trump administration. Some scientists and legal experts see a corollary between the ruling and the administration’s efforts to increase political oversight of federal research, including grantmaking. Questions remain about the decision’s scope and how it will ultimately affect researchers.

AI-designed proteins stabilize unruly membrane proteins

| Chemical & Engineering News (C&EN) Verified
David Baker’s research team at the Institute for Protein Design has unveiled a new technique for sequestering membrane proteins (Science 2026, DOI: 10.1126/science.adr3817). Proteins bound in cell membranes are not soluble in water or stable outside that amphiphilic membrane. This makes working with them difficult, whether to determine their structure or to potentially use them as a vaccine antigen.

Fleeting borylnitrene finally captured in crystal

|
By Victoria Corless
| Chemical & Engineering News (C&EN) Verified
For decades, chemists have relied on boron-bound nitrenes as fleeting intermediates in synthesis, but no one has been able to directly “see” one. These molecules, also called triplet borylnitrenes, contain a highly reactive, neutral nitrogen atom that features two unpaired electrons with parallel spins. The borylnitrenes rearrange almost instantly, disappearing before their structure can be captured.

Modular syntheses: Putting function first

|
By Carrie Arnold Verified
| Chemical & Engineering News (C&EN) Verified
Key insights Building block chemistry is becoming increasingly popular as a programmable strategy to synthesize complex molecules. Combining mix-and-match components with automation and computation is opening up new ways of making molecules. Proponents say this strategy might force chemists to change their philosophical approach to synthesis. Chemist Christian Schafmeister never passes up a chance to reference his favorite episode of The Simpsons.

Companies withhold info more often for dangerous chemicals, C&EN finds

|
By Leigh Boerner Verified
| Chemical & Engineering News (C&EN) Verified
Sourcing the data To analyze how companies use confidential business information (CBI) claims in chemical reporting, C&EN turned to Chemical Data Reporting (CDR) data under the Toxic Substances Control Act (TSCA). C&EN downloaded CDR reports from 2016, 2020, and 2024. Companies file the reports every year, but the US Environmental Protection Agency releases the reports only every 4 years. For example, the 2024 report contains chemical reporting data for 2020, 2021, 2022, and 2023.

Air Products cancels blue hydrogen project in Louisiana

| Chemical & Engineering News (C&EN) Verified
The industrial gas firm Air Products and Chemicals is canceling its clean hydrogen project in Darrow, Louisiana. The Louisiana Clean Energy Complex would have produced 1,700 metric tons (t) of hydrogen per day via steam reformation of fossil methane followed by carbon capture and sequestration, an approach that yields what’s known as blue hydrogen. The firm will write off $2.9 billion in losses.
