By the mid-1920s it was clear that “things” (electrons, atoms, molecules) long regarded as particles also show wave properties. This fact is the basis for the currently accepted theory of atomic structure. This theory, quantum mechanics, was introduced in 1925. Its foundations were developed very rapidly during the next few years, primarily by Born, Heisenberg […]

Until the 80’s all Olympic Games took place in rich countries, with the only exception of Mexico 68. In the 80’s, Moscow 80, Seul 88 and Sarajevo 84 started a trend that encouraged bids from developing countries with the result that after 2000 over half of all bids have come from this group. This fact […]

Blood from donations is separated into three components: red cells, platelets and plasma, and one component or another is then transfused into patients according to their needs. The conditions for storage differ for each component: red cell concentrates can be kept for up to 42 days at temperatures of 1-6ºC. Platelet concentrates (PC) are stored […]

Earth-sun magnetic field interactions seen by NASA space probes Explosive storms spawned by interactions between the magnetic fields of Earth and the sun can endanger satellites, spacecraft and astronauts in space, as well as power grids on Earth. Now, a fleet of NASA spacecraft has for the first time directly witnessed the mysterious way in […]

In previous posts, we have discussed the two main loopholes of Bell experiments, the locality loophole, and the detection loophole. Both were closed a long time ago, but only recently they were closed in the same experiment. Let us summarize the kind of experiments we are dealing with by an example. Alice and Bob will […]

Venus flytraps’ predatory ways may have roots in defense The genes that allow Venus flytraps to be carnivores may come from defensive mechanisms carried over from their non-insect-eating ancestors. Researchers found that gene expression patterns shift radically when prey steps into the plants’ traps, signaling digestive enzymes along the same protein paths used to help […]

Nonhuman primates may be involved in Zika transmission Scientists who collected biological samples from 15 wild marmosets and eight pet capuchin monkeys plus one free-ranging capuchin in Brazil found four marmosets and three capuchins had been infected with the Zika virus. The Scientist Cosmic-particle technology opens window into Bent Pyramid New cosmic-particle technology has allowed […]

As an intellectual discipline, moral philosophy is afflicted by a very deep ambivalence. On the one hand, moral philosophers have always pursued to have a prominent position in the debates about what is morally good and what is morally bad; most of their theories can be interpreted hence as sophisticated attempts to answer the old-as-mankind […]

Dali painting used in study of how brain processes information Scientists used a painting by Salvador Dali to help them discover how the brain processes information. Researchers asked study participants to examine Dali’s 1940 work “Slave Market with the Disappearing Bust of Voltaire,” which is visually ambiguous. “We found very early on … that the […]

Neanderthals ( Homo neanderthalensis ) were a species –some say a subspecies although most authors consider there is enough evidence to consider them as a separate species– of human closely related to us. They were firstly discovered in a cave in the Neander Valley («Tal» in German), about 12 km east of Düsseldorf. There is […]
