Gravitational wave detectors could soon uncover hints of new physics from exotic compact objects.
Great episode from a great channel and creator. Though I’m sure almost everyone here is familiar with the channel in question, It’s still worth pointing out subscribing and supporting even if only 1 or 2 people who otherwise haven’t heard it get the opportunity to do so!

As Humanity moves into the future, traveling to other worlds and exploring genetics, AI, transhumanism, and cybernetics, we may begin to diverge into a thousand post-human species.
This shows also the hertz of reality circa 2016.
Long ago, deep in space, two massive black holes—the ultrastrong gravitational fields left behind by gigantic stars that collapsed to infinitesimal points—slowly drew together. The stellar ghosts spiraled ever closer, until, about 1.3 billion years ago, they whirled about each other at half the speed of light and finally merged. The collision sent a shudder through the universe: ripples in the fabric of space and time called gravitational waves. Five months ago, they washed past Earth. And, for the first time, physicists detected the waves, fulfilling a 4-decade quest and opening new eyes on the heavens.

A power-beaming experiment is scheduled to launch in 2024.
Space-based solar power won’t be just a sci-fi dream forever, if things go according to the U.S. Air Force’s plans.
The arrival of one Crew Dragon capsule sets the stage for the departure and return to Earth of another.
A team led by Prof. GUO Guangcan and Prof. ZOU Changling from the University of Science and Technology of China of the Chinese Academy of Sciences realized efficient frequency conversion in microresonators via a degenerate sum-frequency process, and achieved cross-band frequency conversion and amplification of converted signal through observing the cascaded nonlinear optical effects inside the microresonator. The study was published in Physical Review Letters.
Coherent frequency conversion process has wide application in classical and quantum information fields such as communication, detection, sensing, and imaging. As a bridge connecting wavebands between fiber telecommunications and atomic transition, coherent frequency conversion is a necessary interface for distributed quantum computing and quantum networks.
Integrated nonlinear photonic chip stands out because of its significant technological advances of improving nonlinear optical effects by microresonator’s enhancing the light-matter interaction, along with other advantages like small size, great scalability, and low energy consumption. These make integrated nonlinear photonic chips an important platform to covert optical frequency efficiently and realize other nonlinear optical effects.

Hebrew University Researcher Introduces New Approach to Three-Body Problem, Predicts its Outcome Statistics.
The “three-body problem,” the term coined for predicting the motion of three gravitating bodies in space, is essential for understanding a variety of astrophysical processes as well as a large class of mechanical problems, and has occupied some of the world’s best physicists, astronomers and mathematicians for over three centuries. Their attempts have led to the discovery of several important fields of science; yet its solution remained a mystery.

Deleting another spam email in our inbox is becoming an everyday habit. Some may have even had their accounts hacked after clicking a misleading link or had their identities stolen. These are some common cybercrimes and as our reliance on the internet grows, our interactions with cybercrimes becomes more frequent.
According to a recent FBI report on internet crime, 241342 Americans fell victim to phishing, vishing (via call) and smishing (via text) attacks last year, making it the most common type of cybercrime.
This chart shows the most common types of internet crimes in the U.S. in 2020.
“More than 100 malaria vaccine candidates have entered clinical trials in recent decades, but none has shown efficacy greater than 75% – until now.” https://www.futuretimeline.net/images/socialmedia/
Researchers led by the University of Oxford have completed a Phase II trial of R21/Matrix-M, a candidate malaria vaccine, which demonstrated an efficacy of 77% over 12-months of follow-up.
In their findings, posted on SSRN/Preprints with The Lancet, they note that their study is the first to reach the World Health Organization’s goal for a vaccine with at least 75% efficacy by 2030. It represents a substantial improvement over the current most effective malaria vaccine, which has shown just 55% efficacy in trials on African children.
