Massive gas cloud boomeranging back to Milky Way A massive gas cloud that was almost ejected from the Milky Way is hurtling back to our galaxy, according to findings gathered from new observations by the Hubble Space Telescope. Dubbed the Smith Cloud, it is expected to smash into the galactic plane in about 30 million […]

In the early days of organic chemistry, the word aromatic was used to describe fragrant substances such as benzene (from coal distillate), benzaldehyde (from cherries, peaches, and almonds), and toluene (from tolu balsam). It was soon realized, however, that substances classed as aromatic differed from most other organic compounds in their chemical behaviour. Today, the […]

A review of the book: The brain electric: The dramatic high-tech rage to merge minds and machines by Malcolm Gay Flying cars, self-tying shoes or a fully functional hoverboard are only a few examples of the inventions which, according to the time-travel adventure sequel Back to the Future Part II, should be available for purchase […]

“We asked for workers. We got people instead.” Max Frisch In a past article, I reviewed the recent literature on the effects of immigration on the labor market. To sum up, it finds no significant negative effects on employment or wages of native workers while it boosts the local economy. From here, one may be […]

Noodle-, hazelnut-shaped plasma lenses may be hiding in Milky Way Scientists are learning more about the shape of mysterious plasma lenses, which seem to invisibly float around the Milky Way, detected through radio waves. Researchers were able to detect a lengthy lensing event that gave them an idea of the shapes of the lenses. Space.com […]

At a fundamental level the term “quantum computing” implies de use of quantum effects that have no classical analogue to process information. In a “classical computer” information is held in bits, which can have two alternative values (0 and 1). quantum computer the values 0 and 1 are held simultaneously in an entangled state. This […]

Animals drift when they enter a fluid (liquid or gas) and are transported to a new location by gravity or currents. Drift is best known from rivers and ocean currents, but can also occur on land, whenever organisms leave their former solid position, pass into the air, and are moved significant distances by the combined […]

The usage of the words “Eskimo” and “Inuit” is one of these cases in which, all of a sudden, we are told we have been saying something wrong all along. Lawrence Kaplan from the Alaska Native Language Centre at the University of Alaska Fairbanks explained that the words “Eskimo” and “Inuit” do not mean the […]

Fish communicate to stay close to each other Fish use calls to stick together as a group, a new study suggests. Researchers played recordings of bigeye vocalizations for captive wild bigeyes, and noted that their own vocalizations increased and they swam more closely together than they did when no recordings were played. “This study means […]

In 1928, just two years after the formulation of quantum mechanics, the German physicist Arnold Sommerfeld modified the classical free-electron model by treating the electrons according to quantum mechanics. But the new theory still contained the unrealistic assumption that the electrons do not interact with the charged lattice ions except to collide with them. As […]
