Controlled Chemical Signaling between Enzymatic Nanomotors
arXiv:2606.04138v1 Announce Type: cross Abstract: The coordinated interactions between organisms enhance collective functionality, a feature that artificial systems such as enzymatic nanomotors seek to replicate. A key objective, yet still a major challenge, is to achieve chemical communication among nanomotors. Progress has been limited by the difficulties in verifying effective signaling processes, including chemical signal propagation and the response of receiving nanomotors.
Cold-grown plankton shells sharpen Arctic climate reconstructions
Cold-grown plankton shells sharpen Arctic climate reconstructions Sadie Harley Scientific Editor Robert Egan Associate Editor Researchers at iC3 have found a way to improve records of past high latitude ocean change using tiny plankton shells called foraminifera. By growing these foraminifera under controlled cold-water conditions, the team has extended a key temperature tool into the range most relevant for subpolar and polar oceans. The study's results matter for anyone using marine...

Light-induced quantum friction of carbon nanotubes in water
Abstract Friction slows down moving objects at both macroscopic and microscopic scales1. At the electronic level, quantum friction describes direct transfer of momentum between a liquid and the electrons of a solid2. Owing to its microscopic nature, this phenomenon remains experimentally challenging to capture3.
Mitochondria directly interact with the nuclear pore complex
Abstract Mitochondria regulate cellular processes through direct and indirect interactions with other organelles. A well-studied example has been contact with the endoplasmic reticulum at mitochondrial-associated endoplasmic reticulum membranes1, which control pathways including redox and calcium homeostasis2,3. Recent studies have also reported direct mitochondria–nuclear membrane contacts in cancer cells and yeast that promote pro-survival signalling4,5.
Nitric oxide overload jams plant immune signals, researchers find
Nitric oxide overload jams plant immune signals, researchers find Gaby Clark Scientific Editor Robert Egan Associate Editor A new study from the University of Kentucky Martin-Gatton College of Agriculture, Food and Environment (CAFE) helps explain how plants can lose track of their own disease warnings. Plants do not have blood, nerves or immune cells like people do, but they still have ways to protect themselves. When one leaf is attacked by a pathogen, the plant can send warning signals to...
Nanomagnets control diamond qubits, pointing to more scalable quantum hardware
Nanomagnets control diamond qubits, pointing to more scalable quantum hardware Gaby Clark Scientific Editor Robert Egan Associate Editor Quantum computing, once only a theoretical possibility, promises to deliver faster, more energy-efficient computers—but only if scientists can build and scale the hardware needed to run the machines. New research from Virginia Commonwealth University brings scientists one small step closer to quantum computing at a practical scale, which could help...
Molecular glue degraders of HuR suppress BRAF-mutant colorectal cancer
Abstract BRAF gain-of-function mutations, particularly BRAF(V600E), affect roughly 10% of all patients with colorectal cancer (CRC), and portend poor prognosis with limited therapeutic interventions. BRAF inhibitors such as encorafenib are ineffective due to MAPK pathway reactivation driven by BRAF dimerization. Combined inhibition of BRAF and EGFR, although approved therapies, results in short survival benefits and frequent treatment resistance and relapse1,2,3.
Scientists unveil 'living bandage' that could dramatically speed wound healing
A new "living bandage" could soon revolutionize how doctors treat serious injuries by accelerating the healing process, according to new research reported by SWNS.The high-tech patch was developed by researchers at Rice University in Texas. It acts like an around-the-clock mini factory, continuously delivering healing proteins directly to different types of wounds, the same source noted. Caring for chronic wounds is often a challenge for doctors, as it's difficult to deliver steady,...
Comparative Proteomics Across Tissues and Crop Agroecosystems Reveals Agricultural Stressor Responses in the Western Honey Bee
Maintaining honey bee health in crop production systems is increasingly difficult because worker bees encounter multiple chemical and biological pressures from pesticides and pathogens. How these field-realistic pressures affect molecular physiology across functionally distinct tissues remains poorly understood. Here, we tested whether tissue-resolved proteomics could separate stable tissue-specific patterns from crop-associated molecular changes.
