The Meselson–Stahl experiment is an experiment by Matthew Meselson and Franklin Stahl in 1958 which supported Watson and Crick's hypothesis that DNA replication was semiconservative. In semiconservative replication, when the double-stranded DNA helix is replicated, each of the two new double-stranded DNA helices consisted of one strand from ...
The first recombinant DNA molecule was created by Paul Berg in 1972 when he combined DNA from the monkey virus SV40 with that of the lambda phage. [12] Experiments on hereditary material during the time of the Hershey–Chase experiment often used bacteriophages as a model organism.
Benjamin Libet's experiment on free will shows that a readiness potential appears before the notion of doing the task enters conscious experience, sparking debate about the illusory nature of free will yet again. (1983) Vilayanur S. Ramachandran's experiment on phantom limbs with the Mirror Box throw light on the nature of 'learned paralysis ...
Davisson–Germer experiment; Gold foil experiments, performed by Geiger and Marsden for Rutherford which discovered the atomic nucleus; Elucidation of the structure of DNA by X-ray crystallography; Discovery of the antiproton at the Bevatron; Discovery of W and Z bosons at CERN; Discovery of the Higgs boson at the Large Hadron Collider; MINERνA
Hyder, Avery, MacLeod and McCarty used strands of purified DNA such as this, precipitated from solutions of cell components, to perform bacterial transformations. The Avery–MacLeod–McCarty experiment was an experimental demonstration by Oswald Avery, Colin MacLeod, and Maclyn McCarty that, in 1944, reported that DNA is the substance that causes bacterial transformation, in an era when it ...

A group of researchers led by Masato Sakai, a professor of archaeology at Japan’s Yamagata University, has trained an object detection AI model with high-resolution imagery of the 430 Nazca ...
Maurice Hugh Frederick Wilkins CBE FRS (15 December 1916 – 5 October 2004) [2] was a New Zealand-born British biophysicist and Nobel laureate whose research spanned multiple areas of physics and biophysics, contributing to the scientific understanding of phosphorescence, isotope separation, optical microscopy, and X-ray diffraction.
