Radioactivity of the Neutron

THE mass of the neutron (1·00893 mμ) is about 0·8 Mev. greater than that of the hydrogen atom (1·00813 mμ). We should expect that, from Fermi's theory, the neutron would be β^--radioactive with a half-life period ...

Neutron and Negative Proton

ABOUT a year ago, I proposed a method of detecting the decay of the neutron¹. Recently, it has been reported that Kapitza has, in the course of the analysis of cosmic ray spectra, discovered the negative proton. ...

Relative Nature of Electromagnetic Radiation

BY using the method of instantaneous infinitesimal Lorentz transformation, we obtain transformation coefficients connecting the two systems S and S, with S at rest and S in accelerated motion. Here we give these ...

Internal Pair Conversion

WHEN a γ-quantum, emitted from the nucleus of a radioactive atom, is absorbed by the same atomic system, an ordinary electron and a positron may be liberated if the energy of the γ-quantum is greater than 2mc². T...

Free Amino-acids of Isolated Calf Thymus Nuclei

CALF thymus nuclei prepared by the sucrose–calcium chloride method of Allfrey et al.¹ are remarkably biochemically active, as judged by the incorporation of labelled amino-acids into the nuclear proteins^1,2. Such...

Dizygotic Twins with XX/XY Chimerism

CHIMERAS, dizygotic twins who have two populations of blood cells, arise when hæmatopoietic cells are exchanged or shared at some time in early embryonic life. The first case of chimerism in man was reported b...

Inhibition of dopamine biosynthesis by gonadotropin-releasing hormone in rat

There is evidence that the neuroendocrine system can be modulated by endogenous opioid peptides (for a review see ref. 1). Recently Rotsztejn et al.² have ruled out a direct effect of Met-enkephalin on release of...

Structure, sequence and expression of the hepatitis delta (δ) viral genome

Nature 323, 508–514 (1986). A GUANOSINE residue was omitted from the nucleotide sequence of the hepatitis 8 viral (HDV) genomic RNA between residues 1,113 and 1,114 (Figs 4 and 5). HDV RNA therefore consists o...
