Dmitri Mendeleev's paper The Dependence between the Properties of the Atomic Weights of the Elements is read to the Russian Chemical Society in St Petersburg, arranging the known elements by atomic weight and valence and leaving gaps for elements not yet found.

Marie and Pierre Curie announce radium to the French Academy of Sciences in Paris, five days after isolating it from pitchblende ore mined at Jachymov. It is the second element they identify that year, after polonium.

Albert Einstein reads The Field Equations of Gravitation to the Prussian Academy of Sciences in Berlin, giving general relativity its final form after an inconsistency with observation sent him back to the drawing board.

Arthur Eddington presents the results of the May 1919 eclipse expeditions to Principe and Sobral at a joint session of the Royal Society and the Royal Astronomical Society at Burlington House. The measured deflection of starlight matches Einstein's prediction, and the meeting accepts it.

Nature carries Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid, the paper in which Francis Crick and James Watson describe the double helix. It runs to two pages and settles how genetic instructions are held and passed on.

The Roslin Institute reveals that a Finn-Dorset lamb born the previous July was cloned from an adult mammary-gland cell by somatic cell nuclear transfer - the first mammal cloned from an adult somatic cell.

At a seminar at CERN, the ATLAS and CMS experiments each report a new boson at around 125-126 GeV at five sigma, independently and from the same data-taking runs. It is the last unverified piece of the Standard Model.

At a press conference at the National Press Club in Washington, the LIGO and Virgo collaborations announce GW150914, a signal from the merger of two black holes recorded by both LIGO detectors on 14 September 2015 - the first direct observation of gravitational waves.

Metal detectorists Vegard Sørlie and Rune Sætre found 19 silver coins near Rena on 10 April 2026; the excavation by the Museum of Cultural History ended with 4,772 coins buried around 1046-47.

After a resident handed in two gold rings found beside a forest track on 22 April 2026, North Jutland archaeologists recovered six solid gold arm rings weighing 762.5 grams, now declared state property.

Archaeologists from the University of West Bohemia report a nearly circular 230-metre enclosure in Czechia, built about 6,500 years ago, whose twelve entrances align with the Sun and the Moon.

North Jutland Museums announced on 31 August 2026 an 18.5-kilogram hoard of about 700 silver pieces, struck by a homeowner preparing ground for a terrace in Rebild, nearly three times the size of the previous Danish record.

On 3 September 2026 Kalle Lappinen found about 4.5 kilograms of silver coins and objects buried in two birch-bark containers in a forest near Sysmä, far larger than the previous Finnish record from 1895.

A Northumbria University team using the William Herschel Telescope's WEAVE spectrograph found unusually nitrogen-rich gas in the tail of the interstellar comet 3I/ATLAS, pointing to formation at about 30 kelvin far from its home star.

Reprocessing archived Keck images, astronomers have confirmed a Jupiter-size planet less than a million years old, 55 times Earth's distance from its star, forming far faster than planet-formation models allow.

On 21 September 2026 Türkiye announced a cuneiform tablet fragment from the Treaty of Kadesh, covering Articles 12 to 20 on people who fled between Egypt and the Hittite kingdom, unearthed in the Büyükkale area of the Hittite capital.

Using South Africa's MeerKAT array, a Harvard & Smithsonian team reports the first direct detection of auroral radio emission from a planet outside the Solar System, implying a magnetic field of at least 1,250 gauss on the giant planet Beta Pictoris b.

A Science Bulletin study of EP250704a, seen on 4 July 2025, finds the longest prompt X-ray flash ever recorded from a neutron star merger, nearly ten minutes long, as strong evidence that such mergers can leave a magnetar behind.
