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.

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.

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.

“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.”

Aliens Shaped by Natural Selection

In a landmark 2017 study published in the International Journal of Astrobiology scientists from the University of Oxford showed that aliens are potentially shaped by the same processes and mechanisms that shaped humans, such as natural selection and are like us, evolving to be fitter and stronger over time.

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.

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.

It’s known that water ice exists below the lunar regolith (broken rock and dust), but scientists don’t yet understand whether surface ice frost covers the floors inside these cold craters. To find out, NASA is sending Lunar Flashlight, a small satellite (or SmallSat) no larger than a briefcase. Swooping low over the lunar South Pole, it will use lasers to shed light on these dark craters—much like a prospector looking for hidden treasure by shining a flashlight into a cave. The mission will launch aboard a SpaceX Falcon 9 rocket in mid-November.

“This launch will put the satellite on a trajectory that will take about three months to reach its science ,” said John Baker, the mission’s project manager at NASA’s Jet Propulsion Laboratory in Southern California. “Then Lunar Flashlight will try to find on the surface of the Moon in places that nobody else has been able to look.”
