Something spooky is happening at the edge of the solar system

Posted by in categories: particle physics, space

Just in time for Halloween, scientists have discovered something spooky and strange occurring at the edge of the solar system: The heliopause — the boundary between the heliosphere (the bubble of solar wind encompassing the solar system) and the interstellar medium (the material between the stars) appears to be rippling and creating oblique angles in an unexpected manner.

The general concept that the heliopause changes shape is not new; over the past decade, researchers have determined that it is not static. They made this discovery using data from Voyager 1 and Voyager 2, the only two spacecraft to exit the heliosphere thus far, as well as NASA’s Interstellar Boundary Explorer (IBEX) satellite, which studies the emissions of energetic neutral atoms (ENAs) that are created when solar winds and the interstellar medium interact.

19 Key Tips To Beat The Facebook Algorithm & Boost Your Reach [2022]“ data-gatsby-head=”true

Posted by in category: information science

Why does Facebook constantly change its algorithm? I can never keep up.” “We’re the ones giving them money. Why are they always making it harder on us to get our content to our audience?” You’re not alone if you’ve ever asked either of those questions. For years, marketers and advertisers have been noticing changes to Facebook’s algorithm. Each time, these changes only seemed to hurt their organic reach and ad performance with Facebook marketing. Though the Facebook algorithm isn’t the only thing affecting the reach of your content, it is one of the most important. That’s why all marketers must stay up to date on the changes and updates as Facebook rolls them out.


Find out about changes to the Facebook algorithm, how it works, and take away 19 clever tips you can try today to outsmart the algorithm.

How to manage risk as AI spreads throughout your organization

Posted by in category: robotics/AI

Register now for your free virtual pass to the Low-Code/No-Code Summit this November 9. Hear from executives from Service Now, Credit Karma, Stitch Fix, Appian, and more. Learn more.

As AI spreads throughout the enterprise, organizations are having a difficult time balancing the benefits against the risks. AI is already baked into a range of tools, from IT infrastructure management to DevOps software to CRM suites, but most of those tools were adopted without an AI risk-mitigation strategy in place.

Of course, it’s important to remember that the list of potential AI benefits is every bit as long as the risks, which is why so many organizations skimp on risk assessments in the first place.

Study involving CU-Boulder shows fertilizer can be made from sunlight

Posted by in categories: biological, chemistry, food, particle physics

A group of scientists led by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) in Golden and involving the University of Colorado Boulder has developed a new, eco-friendly method to produce ammonia, the main ingredient of fertilizer, using light.

The researchers discovered that light energy can be used to change dinitrogen (N2), a molecule made of two nitrogen atoms, to ammonia (NH3), a compound of nitrogen and hydrogen. The researchers hope the newly discovered, light-driven chemical process that creates ammonia can lead to future developments that will enhance global agricultural practices while decreasing the dependence of farmers on fossil fuels.

Traditionally there have been two main ways to transform nitrogen, the most common gas in Earth’s atmosphere, for use by living organisms. One is a biological process that occurs when atmospheric nitrogen is “fixed” by bacteria found in the roots of some plants like legumes and then converted to ammonia by an enzyme called nitrogenase.

Darwin’s Extraterrestrials

Posted by in categories: alien life, chemistry

“By now it has become a common futurist prediction and science fiction plot device that intelligent and sentient life forms can be created which are not biochemical in nature and are thus fundamentally different from all currently known life,” distinguished Princeton astrophysicist Edwin Turner wrote in an email to The Daily Galaxy. “Whether or not this would actually be possible,” he explains, “depends on the nature and origin of consciousness, a topic about which we have little more than entertaining whistling-in-the-dark guesses at this point and no clear path toward obtaining any better understanding of this deep mystery.”

Light-analyzing ‘lab on a chip’ opens door to widespread use of portable spectrometers

Posted by in categories: biotech/medical, mobile phones, robotics/AI, security

Scientists including an Oregon State University materials researcher have developed a better tool to measure light, contributing to a field known as optical spectrometry in a way that could improve everything from smartphone cameras to environmental monitoring.

The study, published today in Science, was led by Finland’s Aalto University and resulted in a powerful, ultra-tiny that fits on a microchip and is operated using artificial intelligence.

The research involved a comparatively new class of super-thin materials known as two-dimensional semiconductors, and the upshot is a proof of concept for a spectrometer that could be readily incorporated into a variety of technologies—including quality inspection platforms, security sensors, biomedical analyzers and space telescopes.

Electrons with Planckian scattering in strange metals follow standard rules of orbital motion in a magnet

Posted by in categories: materials, quantum physics

Strange metals, or non-Fermi liquids, are distinct states of matter that have been observed in different quantum materials, including cuprate superconductors. These states are characterized by unusual conductive properties, such as a resistivity that is linearly associated with temperature (T-linear).

In the strange phase of matter, electrons undergo what is known as “Planckian dissipation,” a high scattering rate that linearly increases as the . This T-linear, strong electron scattering is anomalous for metals, which typically present a quadratic (T2), as predicted by the standard theory of metals.

Researchers at Université de Sherbrooke in Canada, Laboratoire National des Champs Magnétiques Intenses in France, and other institutes worldwide have recently carried out a study exploring the possibility that the resistivity of is not only associated with temperature, but also with an applied . This magnetic field linearity had been previously observed in some cuprates and pnictides, with some physicists suggesting that it could also be linked to Planckian dissipation.
