Weird materials called Weyl metals might reveal the secrets of how Earth gets its magnetic field. The substances could generate a dynamo effect, the process by which a swirling, electrically conductive material creates a magnetic field, a team of scientists reports in the Oct. 26 Physical Review Letters.
The symmetries that govern the world of elementary particles at the most elementary level could be radically different from what has so far been thought. This surprising conclusion emerges from new work published by theoreticians from Warsaw and Potsdam. The scheme they posit unifies all the forces of nature in a way that is consistent with existing observations and anticipates the existence of new particles with unusual properties that may even be present in our close environs.
Advanced propulsion breakthroughs are near. Spacecraft have been stuck at slow chemical rocket speeds for years and weak ion drive for decades. However, speeds over one million miles per hour before 2050 are possible. There are surprising new innovations with technically feasible projects.
NASA Institute for Advanced Concepts (NIAC) is funding two high potential concepts. New ion drives could have ten times better in terms of ISP and power levels ten thousand times higher. Antimatter propulsion and multi-megawatt ion drives are being developed.
The good old times tables lead a very exciting secret life involving the infamous Mandelbrot set, the ubiquitous cardioid and a myriad of hidden beautiful patterns. Time for the Mathologer to go on a serious fact-finding mission.
Ancient continents were found under Antarctic ice, thanks to old data from a now-dead European satellite. New analysis of data from the Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) mission has revealed rocky zones called "cratons" in the Earth's lithosphere, a zone between our planet's crust and mantle.
Cohl Furey, a mathematical physicist at the University of Cambridge, is finding links between the Standard Model of particle physics and the octonions, numbers whose multiplication rules are encoded in a triangular diagram called the Fano plane.
A strange dark matter phenomena is speeding towards the Sun at speeds of 500 kilometers per second according to a new study published in the journal Physical Review D, led by theoretical physicist Ciaran O’Hare from the University of Zaragoza in Spain. The team detected 10 billion solar masses worth of dark matter from an ancient dwarf galaxy swallowed by the Milky Way billions of years ago traveling along S1, streaming directly towards the Sun.
TESS was Launched on April 18th, 2018 by a SpaceX Falcon 9 rocket.
Kepler discovered 2,681 planets outside our solar system and even more potential candidates. It showed us rocky worlds the size of Earth that, like Earth, might harbor life. It also unveiled incredible super Earths: planets bigger than Earth but smaller than Neptune.
New research provides evidence that delusion-prone individuals, dogmatic individuals, and religious fundamentalists are more likely to believe fake news. The study, which appears in the Journal of Applied Research in Memory and Cognition, suggests that the inability to detect false information is related to a failure to be actively open-minded.
NASA’s Hubble Space Telescope returned to normal operations late Friday, Oct. 26, and completed its first science observations on Saturday, Oct. 27 at 2:10 AM EDT. The observations were of the distant, star-forming galaxy DSF2237B-1-IR and were taken in infrared wavelengths with the Wide Field Camera 3 instrument. The return to conducting science comes after successfully recovering a backup gyroscope, or gyro, that had replaced a failed gyro three weeks earlier.
Taller people have a greater risk of cancer because they are bigger and so have more cells in their bodies in which dangerous mutations can occur, new research has suggested.

In other science news, physicists have determined that there is a direct relation between the mass of an object and its weight.
Hidden in a bend of the Mississippi River just south of New Orleans, 29 concrete bunkers lie on a grid of dirt and grass roads. Some hold remnants from the past — 40-year-old gas masks and biohazard signs still hang on a wall. Most of them have been abandoned for decades. But inside two of those bunkers, 15 million fish eyes stare at the walls through the glass of their jars. This is the Royal D. Suttkus Fish Collection, the largest collection of preserved fish in the world, and almost no one knows it exists.
Personality tests are hugely popular, though if you ask working psychologists, they’ll tell you the results are little better than astrological signs. But a new study, based on huge sets of personality data representing 1.5 million people, has persuaded one of the staunchest critics of personality tests to conclude that maybe distinct personality types exist, after all.

In a report published Monday in the journal
Nature Human Behavior, researchers at Northwestern University in Illinois identify four personality types: reserved, role models, average and self-centered.

The new approach was nothing like the basis for widely used personality tests such as the Myers-Briggs, which spits out a personality type with acronyms like INTJ...or ESFP...
A pear seedling selection named Bradford was cloned by the gazillion to become the ubiquitous street tree of America’s postwar suburban expansion. Then it turned invasive.

Its invasive tendencies became widely noticed by the late 1990s, and by the mid-2000s, it had become a weed in the District and 19 states, from Texas to New York. “While callery pear was introduced with the best of intentions, it now seems that a plague is truly upon us,” botanist Michael Vincent wrote at the time. It has now spread to 29 states.
