Nobel Prize 2025 in Medicine
The 2025 Nobel Prize in Physiology or Medicine has been
awarded to Mary E. Brunkow, Fred Ramsdell, and Shimon
Sakaguchi for their pioneering discoveries on peripheral immune
tolerance — a fundamental mechanism that keeps the human
immune system from attacking its own tissues. Their work has
not only transformed our understanding of how the immune
system is regulated but also opened up new avenues for the
treatment of autoimmune diseases, cancer, and transplant
rejection.
Nobel Laureates Winner In Physiology Or Medicine 2025
- Mary E. Brunkow – Senior Program Manager, Institute for
Systems Biology, Seattle, USA. - Fred Ramsdell – Scientific Advisor, Sonoma Biotherapeutics,
San Francisco, USA. - Shimon Sakaguchi – Distinguished Professor, Immunology
Frontier Research Center, Osaka University, Japan.
Award Citation: “For their discoveries concerning peripheral
immune tolerance.”
Their collaborative research identified regulatory T cells (Tregs)
— specialized immune cells that act as “security guards” to
prevent immune cells from mistakenly attacking the body’s own
tissues. This discovery has revolutionized immunology and
disease treatment strategies.
Groundbreaking Discoveries in Immune Tolerance
Understanding Peripheral Immune Tolerance - Our immune system defends the body against countless
microbes daily. - However, it must also distinguish between foreign invaders
and the body’s own cells. - If this balance is disturbed, it can lead to autoimmune
diseases, where the immune system mistakenly attacks
healthy tissues. - The laureates’ research focused on how this balance is
maintained outside the thymus, a mechanism now known as
peripheral tolerance.
Nobel Prize in Physics 2025
The Nobel Prize in Physics 2025 has been awarded to John Clarke,
Michel H.Devoret, and John M. Martinisfortheir groundbreaking
discovery of macroscopic quantum mechanical tunnelling and
energy quantisation in an electric circuit. Their work proved that
quantum phenomena can occur even in large-scale systems,
bridging the gap between the quantum and classical worlds and
paving the way for advanced technologies like quantum
computing, cryptography, and sensors.
Nobel Laureates and Their Contribution
2025 Nobel Physics Winners - John Clarke – University of California, Berkeley, USA
- Michel H. Devoret – Yale University, New Haven, CT /
University of California, Santa Barbara, USA
John M. Martinis – University of California, Santa Barbara,
USA
Research Topic: “For the discovery of macroscopic quantum
mechanical tunnelling and energy quantisation in an electric
circuit”
Quantum Physics Made Visible: The Breakthrough
The Central Question: Size and Quantum Behavior
- One of the fundamental questionsin modern physicsis: How
large can a system be and still exhibit quantum mechanical
effects? - Traditionally, quantum behavior is observable only at the
atomic or subatomic scale. - However, the 2025 Nobel laureates shattered this boundary
by demonstrating quantum phenomena in a macroscopic
electrical circuit, proving that the laws of quantum
mechanics apply even to systems visible to the naked eye.
What is Quantum Physics? - Quantum physics, also known as quantum mechanics, is a
fundamental branch of physics that explains the behavior of
matter and energy at the smallest scales — such as atoms,
electrons, and photons. - Unlike classical physics, which describes predictable and
continuous behavior, quantum physicsreveals a world where
particles can exist in multiple states at once, move through
barriers, and exchange energy in discrete packets (called
quanta).
The Josephson Junction Experiment - The laureates constructed an electronic circuit using
superconductors, materials that allow current to flow
without electrical resistance. - These superconductors were separated by a thin nonconductive barrier, forming a Josephson junction — a device
known for its quantum properties. - By precisely controlling and measuring the properties of this
circuit, they could observe quantum tunnelling and energy
quantisation on a macroscopic scale.
Key Discoveries and Insights
- Macroscopic Quantum Tunnelling
- In quantum mechanics, particles can “tunnel” through
barriers that they classically shouldn’t be able to cross. - In the laureates’ experiment, the entire superconducting
system behaved like a single particle, initially trapped in a
zero-voltage state. - Through quantum tunnelling, it escaped this state — a shift
detectable by the appearance of a voltage — proving that
tunnelling is possible even in large, collective systems.
- Energy Quantisation
- Quantum systems absorb or emit discrete amounts of
energy, not continuous values. - The team demonstrated that their macroscopic system
followed this rule exactly, behaving in accordance with
quantum predictions.
- This finding confirmed that quantum principles govern not
just electrons and photons, but even collective states
involving billions of particles.
Implications for Quantum Technology
This discovery goes beyond theoretical physics — it has practical
implications for emerging technologies, - Quantum Computing – Enables stable and controllable
qubits for faster computation. - Quantum Cryptography – Paves the way for unbreakable
communication systems. - Quantum Sensors – Offers unprecedented precision in
measurement and detection.
“It is wonderful to celebrate how century-old quantum
mechanics still offers new surprises,” said Olle Eriksson, Chair of
the Nobel Committee for Physics. “This discovery opens doors to
a future defined by quantum technology.”

Joel Mokyr’s Insights On Historical Growth - Mokyr used historical evidence to explain why innovation
became self-sustaining after the Industrial Revolution. - He emphasized the need for scientific understanding,
cultural openness to new ideas, and societal acceptance of
change as foundations for continual progress. - His research highlighted that before the modern era,
stagnation was the norm, as discoveries did not consistently
lead to further innovation.
Aghion and Howitt’s Theory of Creative Destruction - In their landmark 1992 paper, Aghion and Howitt developed
a mathematical model of creative destruction, showing how
new innovations displace old technologies. - This process fuels productivity and prosperity but also
creates economic conflicts, as older firms and workers face
displacement. - They emphasized that societies must manage these
transitions constructively to prevent innovation from being
blocked by vested interests.
Broader Impact on Economic Thought - The laureates’ combined work has redefined how
economists understand long-term growth mechanisms. - Their findings underline the importance of innovation policy,
- education, and institutional support to maintain economic
- dynamism.
- Committee Chair John Hassler noted that “economic growth
cannot be taken for granted; we must uphold the
mechanisms of creative destruction to avoid stagnation.”
