Trio win Nobel physics prize for tiny light pulses that capture changes in atoms

The Nobel academy said their studies had given humanity new tools for exploring the movement of electrons inside atoms, where changes occur in a few tenths of an attosecond - a unit so short that there are as many attoseconds in one second as there have been seconds since the birth of the universe.

It was once thought that these changes in electrons could not be seen, but the use of attosecond pulses has changed this, she added. L'Huillier, who received word she had won the prize in the middle of a lecture, told a news conference over the phone, "it is really a prestigious prize and I'm so happy to get it. It's incredible."Hans Ellegren, permanent secretary of the Royal Academy of Sciences, flanked by Eva Olsson and Mats Larsson, members, announces this year's Nobel Prize winners in Physics, at the Royal Academy of Sciences in Stockholm, Sweden October 3, 2023.

While the award for peace can hog the limelight, the physics prize has likewise often taken centre stage with winners such as Albert Einstein and awards for science that has fundamentally changed how we see the world.quantum entanglement

Nobel Prize in medicine awarded to scientists who laid foundation for messenger RNA vaccinesThe Nobel Prize in medicine was awarded to Katalin Kariko and Drew Weissman, scientists who worked together to turn messenger RNA from a fragile genetic material that triggered a problematic immune response into a powerful medicine. Their key breakthrough in 2005 went largely unnoticed, but is now the backbone of two leading coronavirus vaccines and could lead to a whole new class of vaccines and drugs.
