SUMMARY:The Nobel Prize in Chemistry 2025
DESCRIPTION:The Nobel Prize in Chemistry 2025 was awarded to Susumu Kitagawa\, Richard Robson and Omar M. Yaghi “for the development of metal-organic frameworks.” \nThe Nobel Prize laureates in chemistry 2025 have created molecular constructions with large spaces through which gases and other chemicals can flow. These constructions\, metal-organic frameworks\, can be used to harvest water from desert air\, capture carbon dioxide\, store toxic gases or catalyse chemical reactions. \nLinks:\nThe Nobel Prize

SUMMARY:#MoleDay / Wereld Mol Dag 2025
DESCRIPTION:Mole Day is an unofficial holiday celebrated among chemists\, chemistry students and chemistry enthusiasts on October 23\, between 06:02 and 18:02 (6:02 pm)\, making the date 6:02 10/23 in the American style of writing dates. \nThe time and date are derived from the Avogadro number\, which is approximately 6.02×1023\, defining the number of particles (atoms or molecules) in one mole (mol) of substance\, one of the seven base SI units. Schools around the world celebrate Mole Day with various activities related to chemistry and/or moles. For a given molecule\, one mole is a mass (in grams) whose number is equal to the molar mass of the molecule. For example\, the water molecule has an molar mass of 18\, therefore one mole of water weighs 18 grams. Similarly\, a mole of neon has a molar mass of 20 grams. In general\, one mole of any substance contains Avogadro’s Number of molecules or atoms of that substance. This relationship was first discovered by Amedeo Avogadro (1776-1858) and he received credit for this after his death.  \nLinks:\nMole Day \nMol (eenheid)

SUMMARY:DNA Day 2026
DESCRIPTION:DNA Day is a United States holiday celebrated on April 25\, it commemorates the day in 1953 when James Watson\, Francis Crick\, Maurice Wilkins\, Rosalind Franklin and colleagues published papers in the journal Nature on the structure of DNA. \nFurthermore\, in early April 2003 it was declared that the Human Genome Project was very close to complete\, and “the remaining tiny gaps were considered too costly to fill.” In the United States\, DNA Day was first celebrated on April 25\, 2003\, by proclamation of both the Senate and the House of Representatives. However\, they only declared a one-time celebration\, not an annual holiday. Every year from 2003 onward\, annual DNA Day celebrations have been organized by the National Human Genome Research Institute (NHGRI)\, starting as early as April 23 in 2010\, April 15 in 2011 and April 20 in 2012. April 25 has since been declared “International DNA Day” and “World DNA Day” by several groups. Genealogical DNA testing companies and genetic genealogy publishers run annual sales around DNA Day\, seeking interest from the public and promoting their services. \nLinks:\nDNA Day \nESHG DNA Day Essay & Video Contest
