Henri B Kagan and Kenso Soai win Nobel Prize in Chemistry 2026 for spontaneous homochirality resolution

Stockholm [Sweden], October 7 (ANI): The Royal Swedish Academy of Sciences on Wednesday (native time) awarded the 2026 Nobel Prize in Chemistry collectively to Henri B Kagan and Kenso Soai “for the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis.”

According to an official launch by the Nobel Prize, life’s chemistry is what chemists name homochiral, after the Greek phrases for “same” and “hand”. Like palms, all amino acids exist as two mirrored variants, however solely considered one of them is discovered within the proteins in your cells. The different is never present in nature.

For a very long time, chemists questioned how homochirality can emerge. When they started to experiment with chemical reactions that may type two mirrored molecules, they all the time obtained equal proportions of each of their check tubes.

However, chemists strived to supply solely considered one of these mirror pictures, as a result of within the improvement of molecules that may work together with dwelling beings – equivalent to in prescribed drugs – just one mirror picture could have the specified impact.

The Nobel Prize in Chemistry 2026 recognises discoveries which have enabled chemists to drive chemical reactions that result in homochirality.

“Henri Kagan and Kenso Soai have provided a solution to a chemical mystery that is over a century old: how homochirality can emerge spontaneously. The chemical reactions they have developed are spectacular,” says Heiner Linke, chair of the Nobel Committee for Chemistry, the discharge cited him as saying. 

The launch famous that Henri Kagan took the primary decisive step in 1986, when he found a brand new method of manipulating chemical reactions. This allowed him to create a better extra of one of many mirror pictures than had beforehand been thought potential.

Kenso Soai took the following step. In 1995, a key publication describes how he designed the primary ever chemical response that had the potential to be homochiral. In 2003, he lastly succeeded. He introduced a response wherein solely one of many two potential mirror pictures was fashioned. Other than life itself, nobody had beforehand achieved this feat.

Thanks to Henri Kagan and Kenso Soai, we now know the way homochirality can emerge. Their discoveries have been decisive for chemists who design reactions for the manufacture of prescribed drugs, the discharge emphasised. 

Henri B. Kagan was born in1930 in Boulogne-Billancourt, France and did his PhD in 1960 at Collge de France, France and is the Professor Emeritus on the then Universite Paris-Sud, France. 

Meanwhile, Kenso Soai was born in 1950 in Hiroshima, Japan and has a PhD in 1979 from the University of Tokyo, Japan. He is the Professor Emeritus at Tokyo University of Science, Japan.

The prize carries an award of 12 million Swedish kronor, which can be shared equally among the many three laureates.

Earlier on Tuesday, the Royal Swedish Academy of Sciences awarded the Nobel Prize in Physics 2026 to Francis Halzen”for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin.’

According to an official press release, Francis Halzen realised that ice at the South Pole could be used to track particles known as neutrinos. His vision and scientific leadership have been fundamental to the IceCube Neutrino Observatory – a cubic kilometre of ice that is equipped with light sensors. Using IceCube, researchers can capture neutrinos from extremely energy-rich processes in the distant universe.

Neutrinos are everywhere, but they do not make themselves known. They pass all the way through the Earth and through our bodies without us noticing. Very rarely, a single neutrino will interact with an atomic nucleus, which makes it possible for someone with the right equipment to discover them. 

The release further stated that scientists have long known that the cosmos contains natural particle accelerators, which fire out particles with energies up to a million times more than can be achieved in laboratories on Earth. Much about these sources is mysterious: what are they, where are they, and what are the main processes inside them?

Neutrinos with extremely high energies are created in the same environments as other types of particles. However, unlike other particles, neutrinos reach us without changing direction or losing energy. This means they can provide information that is not available in any other way.

Francis Halzen first presented his vision for capturing neutrinos at the South Pole in 1988. When a neutrino collides with an atomic nucleus, it produces a flash of light that can be tracked by sensors in the clear glacial ice. The South Pole’s ice has many advantages, as it is free from various types of interference and the area is geologically stable, with no earthquakes. Halzen and his idea soon gained the support of other researchers and, just a few years later, preliminary testing was conducted on sensors in ice.

Cosmic neutrinos with extremely high energies are very rare, so an enormous volume of ice is needed to observe an adequate number of collisions. IceCube covers an entire cubic kilometre and was finished in 2011. Researchers soon discovered the first high-energy neutrinos and, a few years later, could publish their discovery of neutrinos that must originate far outside our solar system. The search for the universe’s neutrino sources could begin in earnest, the release noted. 

“Francis Halzen has led a world crew of researchers and engineers who’ve offered us with a implausible instrument. His tenacity and scientific imaginative and prescient have paved the way in which for a brand new sort of astronomy,” says Mark Pearce, Chair of the Nobel Committee for Physics.

The neutrino interactions which might be repeatedly collected by IceCube will present researchers with novel information concerning the violent settings wherein high-energy neutrinos could be created – and will even reveal beforehand unknown cosmic phenomena. 

Francis Halzen was born in 1944  and has received the prize, which carries an award of 12 million Swedish kronor. (ANI)
