At the frontiers of magnetism

by Perikis Livas in Chilon

The smallest possible magnets are the size of a single atom. Now scientists have reached the limits of optimisation of the tiny particles: they have created single atom magnets that are as strong and stable as is physically possible for the class of atoms used.

Researchers Replace Lead With Tin in Promising Solar Cell

by dailyfusion in The Daily Fusion

Northwestern University researchers are the first to develop a new solar cell with good efficiency that uses tin instead of lead perovskite as the harvester of light. The low-cost, environmentally friendly solar cell can be made easily using “bench” chemistry—no fancy equipment or hazardous materials.... Read more »

Entire Star Cluster Thrown Out of its Galaxy

by Perikis Livas in Chilon

The galaxy known as M87 has a fastball that would be the envy of any baseball pitcher. It has thrown an entire star cluster toward us at more than two million miles per hour. The newly discovered cluster, which astronomers named HVGC-1, is now on a fast journey to nowhere. Its fate: to drift through the void between the galaxies for all time.

Shockwave findings set to rewrite scientific theories

by Perikis Livas in Chilon

For the first time an international team of astronomers has measured circular polarisation in the bright flash of light from a dying star collapsing to a black hole, giving insight into an event that happened almost 11 billion years ago.

Search for life on exoplanets more difficult than thought

by Perikis Livas in Chilon

A new study from the University of Toronto Scarborough suggests the search for life on planets outside our solar system may be more difficult than previously thought.

The study, authored by a team of international researchers led by UTSC Assistant Professor Hanno Rein from the Department of Physical and Environmental Science, finds the method used to detect biosignatures on such planets, known as exoplanets, can produce a false positive result.

Kashiwa Japan – A team of researchers led by Robert Quimby at the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) has announced the discovery of a galaxy that magnified a background, Type Ia supernova thirtyfold through gravitational lensing. This is the first example of strong gravitational lensing of a supernova confirms the team’s previous explanation for the unusual properties of this supernova.

The Mystery of “Quantum Resonance Spectroscopy”

by Neuroskeptic in Neuroskeptic_Discover

Can quantum physics help to diagnose schizophrenia and depression? A paper just published in the Journal of Nervous and Mental Disease claims that a technique called ‘quantum resonance spectroscopy’ (QRS) can accurately diagnose various mental health problems. But is it quantum wizardry or magic quackery? According to the authors of the new paper, Zhang et […]The post The Mystery of “Quantum Resonance Spectroscopy” appeared first on Neuroskeptic....
