Chemicals

All chemicals were used without further purification after purchase: gold(III) chloride trihydrate (≥99.9% trace metals basis, HAuCl₄·3H₂O, Sigma-Aldrich), sodium borohydride (99%, NaBH₄, Sigma-Aldrich), sodium iodide (99.999%, NaI,…

Strain culture and DNA extraction

We used a collection of S. cerevisiae isolates that were previously sequenced using short-read sequencing¹⁹. For each isolate, we obtained single colonies from frozen stock on solid YPD (1% yeast extract, 2%…

• Researchers envision taking a patient’s own cells from a tumor biopsy and growing a personalized mini-colon to determine which drug works best for that individual patient.
• The model can be used to test patient-tailored drug…

New images from the James Webb telescope have captured previously unseen details of the gargantuan jets shooting out of the famous black hole M87* — the first-ever black hole to be directly imaged by the Event Horizon Telescope.

The new James…

Device fabrication

We fabricated our devices using procedures similar to those described in ref. ²². A free-standing silicon nitride (SiN) membrane was used as a substrate for our van der Waals assembly that involved four atomically flat…

Use cases for smart materials in space exploration keep cropping up everywhere. They are used in everything from antenna deployments on satellites to rover deformation and reformation. One of the latest ideas is to use them to transform…
