Investigating Cosmic Snowballs Professor David Jewitt CREDIT: NASA INVESTIGATING COSMIC SNOWBALLS Professor David Jewitt and his team at UCLA explore the nature of comets. These fleeting visitors to our cosmic shore are important sources of information, and can help to reveal the origin and evolution of the solar system. Most recently, Professor Jewitt’s team have explained the unusual activity of some of the most distant comets in the solar system.

Nanoscience Prize 2020 Explanatory Notes
NANOSCIENCE PRIZE 2020 EXPLANATORY NOTES Looking inside matter atom by atom Manipulating matter at very small scales — even as precisely as moving single atoms — to create particles and devices with new functionalities is the ultimate ambition of nanoscience and nanotechnol- ogy. None of this could be achieved with- out an imaging technique that allows materials and devices to be studied with atomic resolution. In making their award, the Kavli Prize in Nanoscience committee has selected four scientists who contributed to the develop- ment and use of two types of instrument, generally known collectively as aberration- corrected transmission electron micro- scopes, which can provide information about the structure and other properties of materials with sub-ångström resolution, hence allowing individual atoms to be distinguished.

Science Prizes for the Future Research In
Science Prizes for the Future Research in observational X-ray astronomy, inventions of aberration-corrected lenses in electron microscopes, and the discovery of sensory receptors for temperature and pressure win USD 3 million Kavli Prizes Seven scientists from five countries honoured for breakthrough discoveries in astrophysics, nanoscience and neuroscience May 27, 2020 (OSLO) — The Norwegian Academy of Science and Letters today announced the 2020 Kavli Prize Laureates in the fields of astrophysics, nanoscience and neuroscience. This year’s Kavli Prize honours scientists whose research has transformed our understanding of the very big, the very small and the very complex. The laureates in each field will share 1 million USD. This year’s Kavli Prize Laureates are: • Kavli Prize in Astrophysics: Andrew Fabian (UK) • Kavli Prize in Nanoscience: Harald Rose (Germany), Maximilian Haider (Austria), Knut Urban (Germany) and Ondrej L L Krivanek (UK and Czech Republic) • Kavli Prize in Neuroscience: David Julius (US) and Ardem Patapoutian (US) “The 2020 Kavli Prize Laureates represent truly pioneering science, the kind of science which will benefit humanity in a profound way, inspiring both current and future generations,” says Hans Petter Graver, president of The Norwegian Academy of Science and Letters. The 2020 Kavli Prize Laureates Understanding the role of black holes in the ‘ecosystem’ of galaxies The Kavli Prize in Astrophysics is awarded to astronomer and astrophysicist Andrew Fabian for his pioneering research and persistence in pursuing the mystery of how black holes influence their surrounding galaxies on both large and small scales. For decades, researchers have pondered the mechanics and physical processes of galaxies, and many have made discoveries that point to aspects of their inner workings; yet none has the unique vantage point of Fabian: to take a multi-scale understanding and systematically know where to look to put the pieces of the puzzle together and create the bigger picture of this vast ecosystem.

Nanoscience Prize Explanatory Notes
N A N O S C I E N C E P R I Z E EXPLANATORY NOTES THE ability to control the basic building blocks of matter on a very small scale is one of the core themes of nanoscience. Being able to put atomic, molecular, and nanoscale species where we want them provides new understanding of quantum properties and allows us to create new structures from scratch with a wide range of potential applications. In making their award, the Kavli Nano- science Prize Committee has chosen two scientists whose development of unprece- dented ways to control matter on the nano- scale have greatly pushed forward the boundaries of human knowledge and proved highly influential in inspiring hun- dreds of others to follow in their footsteps.
