The Large Hadron Collider has been the subject of a few upgrades and maintenance processes in the past two years, as a short-circuit has affected the massive proton smasher badly. The mending seems to have been completed by the physicists in charge of the Large Hadron Collider, who are now confident that the world’s largest particle collider will be operational within the next few days. The Large Hadron Collider is one of the stars of the decade, as it encompasses the work of thousands of people who are trying to figure out the secrets of matter and of the Universe, using the collider. Being on halt for 2 years is a setback for scientists, but at least we have confirmation that the issue could be fixed and the Large Hadron Collider should be back on track in a matter of days.

The European Organization for Nuclear Research has announced yesterday evening that a metal bit that was causing the short-circuit within the large Hadron Collider magnets has been removed over time, and the gargantuan machine is once again fully operational. Today, CERN came forward and said that the Large Hadron Collider would be ready and operational in a couple of days, although they didn’t say how many days they were thinking about.

After the short-circuit, researchers and scientists working on the Large Hadron Collider, its circuits and its components are focusing increasingly more on good maintenance and timely identification of possible problems that the giant might encounter. Since the collider is one of the most important machinery on the planet when it comes to research in the field of physics, you can image the tension around the correct functioning of the device.

Once th Large Hadron Collider is back online, physicists and scientists will focus on working towards an answer to many of their fields’ questions involving matter, anti-matter, neutrinos and their interaction with other particles and many other complex things. During the two years in which the collider lay dormant, CERN worked on making the machine even more powerful and aimed for doubling its performance. The short-circuit happened in March, when the collider was supposed to go online. The biggest and most significant contribution of the Large Hadron Collider to the world of physics is that it provided proof of the Higgs boson to scientists, the particle that gives mass to matter. The discover is a Noel Prize winner in physics from 2013, and with the upgraded collider, CERN hopes to discover even more about the world we live in.

Building a permanent base on the Moon out of things found there is one of the main goals for future exploration. Scientists have attempted to make bricks using a variety of materials, including blood and potatoes. Researchers from the European Space Agency (ESA) have just tried out a new method. They 3D-printed LEGO bricks from stuff that was formed in space billions of years ago. They work just like regular LEGO bricks, which means that stepping on one would still hurt.

Regolith, which is soil made of sharp rocks, covers the moon’s surface. It was formed by meteor impacts and charged particles from the sun and other places over billions of years. We don’t have that on Earth, but we can make something that looks like it by mixing it with polylactide, a bio-based polymer that breaks down naturally.

The mix was more realistic because it had a third ingredient. They ground up a meteorite that fell in North Africa in 2000 and added it to the mix. Meteorite dust is the closest thing to regolith that we have on Earth. The end result is a strong brick that looks great in space gray.

Even though the 3D printing process adds flaws that regular bricks don’t have, the space LEGO bricks work the same way as regular ones and click together. But the experiment does show that it is possible to make structures from Moon materials that can fit together. This gives us a lot of options when we think about building bases for a possible future mission.

“No one has ever built something on the Moon, so it was fun to be able to try out different designs and building methods with our space bricks.” ESA Science Officer Aidan Cowley said in a statement, “It was fun and helpful for learning about the limits of these techniques from a scientific point of view.”

“I love creative building, and so did my team. We thought it would be fun to see if space dust could be shaped into a brick like a LEGO brick so we could try out different ways to build.” “It’s amazing, and the bricks may look a little rougher than usual, but the clutch power still works, so we can play with and test our designs,” Cowley said in a second statement.

The test will now be used to get younger people interested in science and engineering. The bricks will be on display at many LEGO stores in the US, Canada, Europe, and Australia until September 20.

“Everyone knows that scientists and engineers in the real world sometimes use LEGO bricks to test their ideas. An ESA official, Emmet Fletcher, said, “ESA’s space bricks are a great way to get young people interested in space science and show them that play and imagination are also important in space science.”

Imagine a world where information can be transmitted securely across the globe, free from the prying eyes of hackers. Its incredible power lies in the realm of quantum mechanics, making it a groundbreaking advancement with immense potential for the future of telecommunications. There have been obstacles to conquer, but there has also been notable progress, exemplified by a recent achievement from researchers at Harvard University.

Using the existing fiber optics within the city of Boston, the team successfully demonstrated the longest transmission between two nodes. The fiber path covered a total distance of 35 kilometers (22 miles), encircling the entire city. The two nodes that connected to the close path were situated on different floors, making the fiber route not the shortest but rather an intriguing one.

Quantum information has been successfully transmitted over longer distances, showcasing remarkable advancements in this experiment that bring us closer to the realization of a practical quantum internet. The real breakthrough lies in the nodes, going beyond the mere utilization of optical fibers.

A typical network utilizes signal repeaters made of optical fiber. These devices incorporate optical receivers, electrical amplifiers, and optical transmitters. The signal is received, transformed into an electrical form, and subsequently converted back into light before being transmitted. They play a crucial role in expanding the reach of the original signal. And in its present state, this is not suitable for quantum internet.

The issue lies not in the technology, but rather in the fundamental principles of physics. Copying quantum information is not possible in that manner. Quantum information is highly secure due to its entangled state. The Harvard system operates by utilizing individual nodes that function as miniature quantum computers, responsible for storing, processing, and transferring information. This quantum network, consisting of only two nodes, is currently the most extensive one ever achieved, with nodes capable of such remarkable functionality.

“Demonstrating the ability to entangle quantum network nodes in a bustling urban environment is a significant milestone in enabling practical networking between quantum computers,” stated Professor Mikhail Lukin, the senior author.

At each node, a tiny quantum computer is constructed using a small piece of diamond that contains a flaw in its atomic arrangement known as a silicon vacancy center. At temperatures close to absolute zero, the silicon vacancy has the remarkable ability to capture, retain, and interconnect pieces of data, making it an ideal choice for a node.

“Given the existing entanglement between the light and the first node, it has the capability to transmit this entanglement to the second node,” elucidated Can Knaut, a graduate researcher in Lukin’s lab. “This phenomenon is known as photon-mediated entanglement.”

The study has been published in the prestigious journal Nature.

What are the consequences of flying over an earthquake?

Have you ever pondered the potential consequences of being aboard a commercial flight at a significant altitude when a colossal earthquake occurs? Presumably, you would be in an altered state of consciousness that would hinder your ability to perceive and comprehend any sensory experiences, correct? The answer to that question is contingent upon several factors.

Seismic activity and atmospheric conditions
Although it may appear improbable, an earthquake can potentially lead to several consequences that could pose challenges for a flight, depending on the circumstances. However, it is important to first examine the connection between the atmosphere and the earth before delving into that topic.

Attila Komjathy, a scientist at NASA’s Jet Propulsion Laboratory (JPL) of the California Institute of Technology, explained on NASA’s website that when the ground shakes, it generates small atmospheric waves that can travel all the way up to the ionosphere. This is a region known as the exosphere, which can reach a distance of up to 1,000 kilometers (600 miles) from the Earth’s surface.

Consequently, an earthquake has the potential to induce certain atmospheric disruptions, but is this sufficient to disrupt the operation of an aircraft? Simply put, the answer is no. However, if we delve deeper into the matter, the answer remains a resounding no, but with some intriguing nuances.

Earthquakes emit seismic waves, which manifest as pressure waves (P waves) and shear waves (S waves). S waves are restricted to propagating through solid media, such as the ground, while P waves have the ability to transmit through different types of media, including liquids and gases. Consequently, they have the ability to enter the atmosphere. When sound is transformed into soundwaves, they often have a frequency below 20 hertz, which is the minimum level for human hearing. Consequently, these soundwaves, known as infrasound, are usually inaudible.

Nevertheless, as these waves propagate through the air, their intensity diminishes. This phenomenon is known as attenuation, and it essentially refers to the decrease in sound intensity as the distance between the source and the listener increases. It is also a phenomenon that diminishes the intensity of sunlight as it passes through different layers of the atmosphere or other substances, such as the ocean.

Consequently, an aircraft traversing an earthquake, regardless of its intensity, would remain unaffected by the seismic vibrations beneath. Once the P waves have propagated through the rock and subsequently the air, their intensity will have significantly decreased, rendering them overshadowed by the plane’s own noise and movement.

Nevertheless, airplanes are not exempt from risks during an earthquake. The concerns at hand pertain to navigation and safety, albeit of a distinct nature.

In 2018, a self-proclaimed United States Air Force pilot and aero engineer named Ron Wagner provided a response on Quora to a question inquiring about the impact of earthquakes on an aircraft in flight. Wagner’s response was sufficiently captivating that Forbes subsequently shared it again.

Wagner claims that he piloted an aircraft during an earthquake, causing disruptions to air traffic control. During this occurrence, the earthquake resulted in a loss of electricity at the ground base, which consequently affected the plane’s navigation instruments and its capacity to communicate. The power outage resulted in the loss of radar signals for air traffic control, rendering them unable to determine the location of Wagner’s flight. Nevertheless, these problems were quickly resolved when the emergency power of the ground base was activated.

Although this may sound alarming, it serves as an illustration of potential occurrences. Typically, air traffic control stations possess ample emergency backup generators to handle such situations. In addition, they have meticulously developed contingency plans for system-wide events, which include strategies for addressing potential scenarios such as volcanic eruptions, nuclear fallout, floods, acts of terrorism, and earthquakes.

If you find yourself flying during an earthquake, you can rest assured that there is very little cause for concern. Typically, you will be unaware of the occurrence until you touch down.
