It is currently believed that baryon number conservation must be violated to produce a preponderance of baryons over anti-baryons in the early universe. An alternative to violating baryon number conservation is given here that preserves CPT invariance.

The resistivity of human skin depends on the layer within which it is measured. The DC characteristics are fairly well known; here, an experiment that measures the transport of AC signals through the skin is described.

The Kerr-Newman solution to the Einstein field equations has a flat region spanning the ring singularity in the solution; which, unlike the Kerr solution, is not a disk. The nature of this region and its relation to the singularity are the subjects of this paper

The null Killing surfaces for the Kerr and Kerr-Newman solutions to the Einstein field equations are discussed, derived and plotted. For some parameters of the mass m, the angular momentum per unit mass a, and the charge e, the plots show some unusual features, particularly of the Kerr-Newman metric.

From its ancient Greek roots to Lovelock’s groundbreaking 1979 book, the concept of Gaia has evolved to depict Earth as a single, intricate organism sustaining life through the interplay of its organic and inorganic elements. From the Hadean epoch, where life’s emergence radically transformed our planet, to the present, Earth stands as our sole model for understanding life’s potential on other Earth-like worlds. While the lifeforms that evolve on Earth-like planets would not necessarily be identical to those on Earth, they must satisfy the same constraints. These constraints are the central subject of this book.

Before the war that began when Hamas brutally attacked Israel on October 7, 2023, Bahrain,
Morocco, Sudan, and the United Arab Emirates were on the way of normalizing their
diplomaIc relations with Israel and Saudi Arabia seemed poised to do so. This has all been
derailed. Iran is the clear winner.

The concept of exotic charged dust is introduced here to represent dark matter. The term “exotic” means that the dust is not composed of normal matter, and the charge-for lack of a better term-is not an electric charge. It is also shown that the often-used approximate
expression for dark matter density corresponds to an exact solution of the coupled Einstein-Maxwell equations for charged dust. The Einstein field equations tells us is that for a flat universe the cosmological constant acts as a gravitating negative energy distribution that is gravitationally repulsive; following Schwinger, it is shown that the vacuum must have a negative energy spectrum if QFT is to be gauge invariant.

Before the beginning of WW-II, Prime Minister Neville Chamberlain of Britain said in parliament that it was “against international law to bomb civilians as such and to make deliberate attacks on the civilian population.” U.S. President Franklin Roosevelt called civilian bombing “inhuman barbarism.” How cities and their populations during WW-II became military targets in violation of international conventions is explained in this essay.
In has been claimed that the high level of civilian deaths in the 2024 Gaza war is due to Israel dropping some five hundred 2000 pound “bunker busting bombs” in Gaza. It is shown hthat this is not the case.
The number of civilian deaths in Gaza is not exceptionally high in comparison with past wars, and the number would be significantly less if it were not for the well-known Hamas policy of deliberately placing military facilities in high population density areas.

There are no known analytic solutions to the force-free magnetic field equations in coordinates representing Dupin cyclides. Here it is shown that force-free fields can not only have solutions for toroids, as was shown in an earlier paper, but also for cyclides. The fact that the curvature lines of Dupin cyclides are all circles is used to derive a force-free magnetic field on the surface of an elliptic Dupin cyclide.
