An image from John Dalton's A New System of Chemical Philosophy, the first modern explanation of atomic theory.. This timeline of chemistry lists important works, discoveries, ideas, inventions, and experiments that significantly changed humanity's understanding of the modern science known as chemistry, defined as the scientific study of the composition of matter and of its interactions.
Scientists report a new species of mussel named Vadumodiolus teredinicola. [106] Biologists report a new species of jellyfish named Santjordia pagesi. [107] 7 February. Reported science studies suggest that cosmic dust particles may have spread, in a process termed panspermia, life to Earth and elsewhere in the Universe. [108] [109]
[40] In 1978, Christopher Kasparek independently proposed an identical model of discovery and invention which he termed "recombinant conceptualization". [41] 1876: Oskar Hertwig and Hermann Fol independently described the entry of sperm into the egg and the subsequent fusion of the egg and sperm nuclei to form a single new nucleus.

The British Antarctic Survey reports that emperor penguin colonies in Antarctica are nearly 20% more numerous than previously thought, with new discoveries made using satellite mapping technology. [115] [116] New Guinea is determined to be the world's most floristically diverse island with well over 13,000 confirmed species of vascular plants ...
DeepMind used artificial intelligence for the first time to predict protein folding. [1]Singapore became the first jurisdiction to approve the sale of cultured meat. [2]The vaccines produced by Pfizer/BioNTech and Moderna against Coronavirus disease 2019 became the first vaccines developed using messenger RNA [3] and mark the fastest vaccine development and approval, taking only 10 months.
Pais, Abraham ; Inward Bound – Of Matter & Forces in the Physical World, Oxford University Press (1986) ISBN 0-19-851997-4 Written by a former Einstein assistant at Princeton, this is a beautiful detailed history of modern fundamental physics, from 1895 (discovery of X-rays) to 1983 (discovery of vectors bosons at C.E.R.N.)
A provocative new paper by climate scientists including James Hansen warns that future sea level rises may have been dramatically underestimated, and that even 2 °C of global warming is "highly dangerous". [314] Intel and Micron unveil 3D XPoint, a new memory technology that is 1,000 times faster than NAND and 10 times denser than conventional ...
