Unlocking the Universe's Secrets

National Academy of Sciences Honors 2025's Pioneering Scientists

From quantum leaps to interstellar mysteries, this year's awards spotlight science reshaping our future.

The National Academy of Sciences (NAS) has championed scientific excellence since 1863, when President Abraham Lincoln signed its founding charter. Today, it remains a beacon for discoveries that redefine human knowledge. On April 27, 2025, NAS will honor 20 extraordinary researchers at its 162nd Annual Meeting, celebrating breakthroughs from quantum physics to neurobiology. These awards—many targeting early-career scientists—highlight work with profound implications for technology, medicine, and our understanding of the cosmos 1 3 5 .

Decoding the Quantum Leap: Xiaodong Xu's Groundbreaking Experiment

Xu's award-winning work tackles one of physics' most elusive goals: stable quantum bits (qubits). Traditional qubits are highly error-prone, but Xu's discovery of the fractional quantum anomalous Hall effect (FQAHE) in engineered materials opens a path to error-resistant qubits 4 7 .

Methodology: Engineering Quantum Realms

Xu's team executed a meticulous four-stage process:

  1. Material Fabrication
    Stacked atom-thin layers of molybdenum ditelluride (MoTe₂) and tungsten disulfide (WS₂), twisted at 4° to create a "Moiré superlattice."
  2. Cooling & Stabilization
    Chilled the heterostructure near absolute zero (–273°C) and applied a perpendicular magnetic field.
  3. Electrical Probing
    Passed a current through the material and measured longitudinal and Hall resistances.
  4. Topological Signature Detection
    Scanned the magnetic field strength while monitoring resistance.

This discovery opens an exciting frontier in correlated topology. We're thrilled to explore its potential.

Results and Analysis: A New Quantum Era

Xu observed three game-changing phenomena:

A vanishing Rxx accompanied by a quantized Rxy plateau at h/(e²/3) confirmed electrons splitting into fractionally charged particles 4 .

Fractional charge carriers without external magnetic fields—a feat previously deemed impossible. This enables more practical quantum devices 7 .

Exotic quasiparticles that could form the basis of topological qubits resistant to environmental noise 4 .

Beyond Quantum: Other Award-Winning Science

While Xu's work headlines this year's honors, other laureates showcase science's diversity:

Interstellar medium
Interstellar Cartography

Adam Leroy's Henry Draper Medal-winning maps of the interstellar medium reveal how galaxies fuel star birth 1 5 .

Bacteria research

Origin of life
Origins of Life

John Sutherland's studies on prebiotic chemistry earned the Stanley Miller Medal, clarifying how Earth's earliest biomolecules formed 1 5 .

Conclusion: Science as Humanity's Compass

The NAS awards mirror science's dual mission: pushing knowledge frontiers and serving society. From quantum materials that could power unhackable computers to genetics that heal societal wounds, these laureates exemplify why science remains humanity's most vital investment. As nominations open for 2026 awards in AI, climate science, and cognitive psychology 3 9 , one truth resonates: today's curiosity fuels tomorrow's miracles.

I hope the public knows how honored we are to do this research, and how hopeful we are that our hard work will lead to cures.
