Top marketplaces facilitate epic amounts of theft and wash trading, scams are rampant, and the cringe is unbearable. Can it last?
Soft sensing technologies have the potential to revolutionize wearable devices, haptic interfaces, and robotic systems. However, most soft sensing technologies aren’t durable and consume high amounts of energy.
Now, researchers at the University of Cambridge have developed self-healing, biodegradable, 3D-printed materials that could be used in the development of realistic artificial hands and other soft robotics applications. The low-cost jelly-like materials can sense strain, temperature, and humidity. And unlike earlier self-healing robots, they can also partially repair themselves at room temperature.
“Incorporating soft sensors into robotics allows us to get a lot more information from them, like how strain on our muscles allows our brains to get information about the state of our bodies,” said David Hardman from Cambridge’s Department of Engineering the paper’s first author.
How many Dyson Spheres, a hypothetical energy source, could be built around stars in the Milky Way?
Researchers calculated the maximum amount of Dyson Spheres in the Milky Way in order to know what it is they did not find.
Researchers have created a device that enables them to electronically steer and focus a beam of terahertz electromagnetic energy with extreme precision. This opens the door to high-resolution, real-time imaging devices that are hundredths the size of other radar systems and more robust than other optical systems.
Terahertz waves, located on the electromagnetic spectrum between microwaves and infrared light, exist in a “no man’s land” where neither classic electronics nor optical devices can effectively manipulate their energy. But these high-frequency radio waves have many unique properties, like the ability to pass through certain solid materials without the health effects of X-rays. They may also enable higher-speed communications, or vision systems that can see through foggy or dusty environments.
The Terahertz Integrated Electronics Group at MIT, led by Associate Professor Ruonan Han, seeks to bridge this so-called terahertz gap. These researchers have now demonstrated the most precise, electronically steerable, terahertz antenna array, which contains the largest number of antennas. The antenna array, called a “reflectarray,” operates like a controllable mirror with its direction of reflection guided by a computer.
The photos look like a scene out of science fiction: Robot dogs patrolling the US-Mexico border, climbing over harsh terrain to search for threats and contraband.
But these images are real.
The Department of Homeland Security recently released them as it revealed details about how it’s testing the technology.
For centuries, people have dreamed of being driven at speed across the vast oceans of space by winds of light.
As whimsical as the idea sounds, nudging reflective sails slowly towards the speed of light using nothing more than the punch of photons might be our only plausible shot at reaching another star inside of a single human lifetime.
It’s also far easier said than done. Particles of light might be fast, but they don’t push very hard. If you make a sail light enough to feel the inertia of radiation, then the constant barrage of photons could inadvertently damage its material.
The Google-backed AI firm taught a reinforcement learning algorithm to control the fiery plasma inside a tokamak nuclear fusion reactor.
Canaanite religion

Study of the evolution of monotheism is instructive. Jolly Jehovah did not burst forth fully formed overnight. Prof Orly Goldwasser explains how Amen and Ra are “better” Gods than Set of Avaris, the first recorded monotheist deity in her 2006 paper on King Apophis. There is evidence of interchangeable identity between Set and Ba’al Hadad. “According to the Canaanite pantheon, known in Ugarit as ‘ilhm (=Elohim) or the children of El (cf. the Biblical “sons of God”), supposedly obtained by Philo of Byblos from Sanchuniathon of Berythus (Beirut) the creator was known as Elion (Biblical El Elyon = God most High), who was the father of the divinities, and in the Greek sources he was married to Beruth (Beirut = the city). This marriage of the divinity with the city would seem to have Biblical parallels too with the stories of the link between Melkart and Tyre; Yahweh and Jerusalem; Chemosh and Moab; Tanit and Baal Hammon in Carthage. El Elyon is mentioned as ‘God Most High’ occurs in Genesis 14.18−19 as the God whose priest was Melchizedek king of Salem.”
Canaanite religion is the name for the group of Ancient Semitic religions practiced by the Canaanites living in the ancient Levant from at least the early Bronze Age through the first centuries of the Common Era. Canaanite religion was polytheistic or monolatristic, worshiping one god while acknowledging the existence of others. The sources for Canaanite religion come either from literary sources written by the early Hebrews, or from archaeological discoveries. The Canaanite wrote on papyrus and.
In a way, it could mean climate change is linked to an “immature technosphere”.
It’s called an epiphenomenon.
The idea is that the ordinary function of one thing can generate a secondary effect that seems unrelated and beyond its scope of influence. And when it comes to the interconnected systems of the Earth, we see it all the time.
Plants, for example, found their way via evolution to photosynthesis, which greatly improved their survival. But it also led to them releasing oxygen into the atmosphere, and that changed everything: One form of life seeded a planet-wide transformation, just by pursuing its own nature.
