Perhaps, topics that involve Extraterrestrial Intelligence are one of the most daunting tasks to write about. Having no formal proofs for their existence, and still knowing that anything, including the existence of Extraterrestrial Life, is possible, it is even more complicated to think about what they are based on, what shapes, sizes, and forms, they have – if they do exist. Extraterrestrials have been a major topic for SciFi; many books have been written and as many movies, if not more, have been produced.

Mysterious iron X-ray lines grow stranger with high precision measurements
Two prominent X-ray emission lines of highly charged iron have puzzled astrophysicists for decades because their measured and calculated brightness ratios always disagree. This hinders good determinations of plasma temperatures and densities. New, careful high-precision measurements, together with top-level calculations, now exclude all hitherto proposed explanations for this discrepancy, and thus deepen the problem.

Quantum effect observed in 'large' metal
In the world of materials science, sometimes main discoveries can be found in unexpected places. While working on the resistivity of a type of delafossite—PdCoO2—researchers at EPFL's Laboratory of Quantum Materials discovered that the electrons in their sample did not behave entirely as expected. When a magnetic field was applied, the electrons retained signatures of their wave-like nature, which could be observed even under relatively high temperature conditions and appeared in relatively large sizes. These surprising results, obtained in collaboration with several research institutions, could prove useful, for example in the quest for quantum computing. The research will be published today in the prestigious journal Science.

Astronomers say they have discovered a black hole on our doorstep, just 1,000 light-years from Earth. It was found in a system called HR 6819, in the constellation Telescopium. The system appears through a telescope as a single bright star, but telltale signs in the light emitted have previously revealed there to be two stars present.

The exact properties of these systems are notoriously difficult to study. In the journal Physical Review Letters, physicists from Martin Luther University Halle-Wittenberg (MLU) and Ludwig Maximilian University Munich have proposed a new theory to describe these quantum systems more effectively and comprehensively.

It was 1919. Robert Goddard had released his research paper titled – \”A Method of Reaching Extreme Altitudes\”. In this paper, he had claimed that a liquid powered rocket had enough potential to take objects along with it to space, and go as far as the moon. The New York Times, on 13th January 1920, ridiculed him for his claims.

How to get rid of the coffee-stain effect
The coffee-stain effect is a well-known effect in physics and daily life in which a dark-colored edge remains when a fluid containing particles evaporates. This is caused by an "avalanche" of particles moving to the outer edge, University of Twente scientists showed in a past study. In inkjet and 3-D printing, this is an undesired effect. Now, researchers have demonstrated that the effect can be suppressed by modifying the surface using an oily layer, according to results published in the Proceedings of the National Academy of Sciences (PNAS).

Physicists introduce novel mechanism for electron optics in solid-state systems
Electrons can interfere in the same manner as water, acoustical or light waves do. When exploited in solid-state materials, such effects promise novel functionality for electronic devices, in which elements such as interferometers, lenses or collimators could be integrated for controlling electrons at the scale of mirco- and nanometres. However, so far such effects have been demonstrated mainly in one-dimensional devices, for example in nanotubes, or under specific conditions in two-dimensional graphene devices. Writing in Physical Review X, a collaboration including the Department of Physics groups of Klaus Ensslin, Thomas Ihn and Werner Wegscheider in the Laboratory for Solid State Physics and Oded Zilberberg at the Institute of Theoretical Physics, now introduces a novel general scenario for realizing electron optics in two dimensions.

The chances of anything coming from Mars have taken a downward turn with the finding that the surface of the red planet contains a “toxic cocktail” of chemicals that can wipe out living organisms. Experiments with compounds found in the Martian soil show that they are turned into potent bactericides by the ultraviolet light that bathes the planet, effectively sterilizing the upper layers of the dusty landscape.

Electrons in strange metals dissipate energy as fast as they're allowed to under the laws of quantum mechanics, and the electrical resistivity of a strange metal, unlike that of ordinary metals, is proportional to the temperature.
