The basic physics for plasma core rocket engines was already completed in 1985. At the time successful containment of a fissioning uranium hexafluoride U(93%)F6 plasma was achieved for ~120 seconds using an argon vortex. Unfortunately, hydrodynamic confinement of a fissioning fuel in a gas core nuclear rocket without uranium loss is probably unachievable. This article proposes a plasma core that is magnetically contained and uses one of many possible stable force-free magnetic field configurations.
Alterations in Human EEG Activity Caused During Exposure to Low Frequency Electromagnetic Fields
It has been known for some time that AC electromagnetic fields of less than 50 Hz can alter the EEG traces of human subjects. Here AC signals of 10 Hz or 20 Hz were applied to the temples of a human subject while recording the monitored EEG traces. It was found that there were significant variations in the traces in both amplitude and frequency during the test period.

Topology and the Baryon-Antibaryon Asymmetry in the Early Universe
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.

AN EXPERIMENT ON THE ELECTRICAL PROPERTIES OF HUMAN SKIN FOR AC VOLTAGES OF VARYING FREQUENCY
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.

FLAT REGIONS NEAR THE KERR-NEWMAN SINGULARITY
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

Null-Killing Surfaces of the Kerr and Kerr-Newman Solutions of the Einstein Field Equations
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.

Life on Earth-like Planets: Gaia and Her Sisters
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.

THE WAR BETWEEN HAMAS AND ISRAEL: IRAN IS THE WINNER
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 ORIGIN OF DARK MATTER AND THE COSMOLOGICAL CONSTANT
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.

GAZA & THE BOMBING OF CITIES AND CIVILIANS
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.
