MolChord: An AI Matchmaker for Proteins and Potential Drugs

MolChord in a nutshell

Designing new medicines often means finding the right small molecule that “fits” a target protein. MolChord is an AI system that acts like a matchmaker, aligning protein shapes with potential drug molecules—and the words scientists use to describe them.

Speaks multiple “languages”: connects 3D structures, sequences (FASTA for proteins, SMILES for molecules), and plain text using NatureLM plus a diffusion-based structure encoder.
Optimizes for the right traits: steers generated molecules toward desired properties with a property-aware dataset and Direct Preference Optimization (DPO).
Proven on benchmarks: achieves state-of-the-art results on the CrossDocked2020 dataset.

Why it matters: better alignment between proteins and candidate drugs can narrow the search space and surface more promising designs, potentially accelerating early-stage discovery.

Beyond URLs: Metadata That Makes LLMs Train Faster

Smarter LLMs, Faster—thanks to metadata What if training a large language model didn't just rely on text, but on the context around it? This study shows that adding fine-grained metadata—not just URLs—can meaningfully speed up pretraining and improve quality. * Beyond URLs: detailed quality signals (e.

Escaping the Verifier: Learning to Reason via Demonstrations

LLMs can learn to reason—without task verifiers Many real-world problems don’t have automatic checkers to grade answers, even though we have lots of expert solutions. RARO (Relativistic Adversarial Reasoning Optimization) shows how to train reasoning skills from those examples alone. How it works: * A policy (the model) tries

VacuumVLA: A Two-in-One Robot Hand That Grips and Suctions

Robots guided by Vision-Language-Action (VLA) AI are getting better at everyday tasks—but most still use simple two-finger grippers. That limits them on smooth, flat, or handleless objects. VacuumVLA is a low-cost robot hand that merges a standard two-finger gripper with a vacuum suction cup. The robot can switch between

ChatDRex: No‑Code, Conversational AI for Drug Repurposing

Meet ChatDRex Finding new uses for approved drugs can save years and millions. But making those predictions usually takes teams of specialists and a tangle of tools. ChatDRex changes that. It’s a conversation-based, no‑code, multi‑agent system that lets clinicians and researchers ask complex bioinformatics questions in plain
