Researchers at the National Graphene Institute at the University of Manchester have achieved a significant milestone in the field of quantum electronics with their latest study on spin injection in graphene. The paper, published recently in Communications Materials, outlines advancements in spintronics and quantum transport.

Mars, the next frontier in space exploration, still poses many questions for scientists. The planet was once more hospitable, characterized by a warm and wet climate with liquid oceans. But today Mars is cold and dry, with most water now located below the surface. Understanding how much water is stored offers critical information for energy exploration, as well as life sustainability on the planet.
To develop a practical fusion power system, scientists need to fully understand how the plasma fuel interacts with its surroundings. The plasma is superheated, which means some of the atoms involved can strike the wall of the fusion vessel and become embedded. To keep the system working efficiently, it’s important to know how much fuel might be trapped.
A new study from the University of Eastern Finland (UEF) explores the behavior of photons, the elementary particles of light, as they encounter boundaries where material properties change rapidly over time. This research uncovers remarkable quantum optical phenomena that may enhance quantum technology and paves the road for an exciting nascent field: four-dimensional quantum optics.
Chinese astronomers have analyzed the data from NASA’s Swift observatory, which extensively observed an outburst of the cataclysmic variable system known as GK Persei. Results of the study, published February 20 on the arXiv preprint server, shed more light on the nature of this system.
Geochemical evidence from laboratory experiments for a potential solid inner core at the center of Mars is reported in Nature Communications.
Intuitive Machines made history last year as the first private company to put a robot on the moon, although the triumph was marred by the lander tipping onto its side.
Best Examples of Inca and pre-Inca masonryIn this article, we bring you some of the best examples of Inca and pre-Inca masonry. I think that we can all agree that the Inca and pre-Inca cultures had incredible construction skills. Proof of their talent are ancient cities such as Puma Punku, Tiahuanaco, Machu Picchu and Ollantaytambo. There, we can find huge blocks of stone that were brought to these cities by unknown means, they had the ability to quarry andesite which is one of the most difficult stones to work with even today. Just how ancient mankind achieved all of this thousands, of years ago is still a mystery that mainstream science cannot solve. How did ancient many quarry, cut, transport, and place into position blocks of stone that weigh over 50 tons? Where did ancient man obtain the knowledge to do so? At Ollantaytambo, we have incredible stonemason details that are also found in Puma Punku, Tiahuanaco, and Sacsayhuaman, walls which are placed so precisely together that not a single sheet of paper can fit in-between them. The question that no one has been able to answer is… how did the ancients achieve all of this? If you take in count that some of these sites are believed to be over 10,000 years old… you have to ask yourself what did ancient mankind know back then that we are missing today? Are we looking at some sort of lost technology? Advanced ancient technology that has been lost in space and time.
After you go through all of the images we have in this article, let us know what are your thoughts on how ancient mankind managed to erect incredible structures like those found at Ollantaytambo, Puma Punku, Tiahuanaco, Machu Picchu and Sacsayhuaman. Is it possible that ancient Inca and pre-Inca builders had incredible skills and lost technology which allowed them to achieve such majestic structures? Or did our ancestors erect these structures with the use of wood, stone, and bronze tools like mainstream researchers suggest? Do you think that modern-day engineers could erect such monuments and make them last thousands of years just as the Inca and pre-Inca? Here are images of the ancient structures found at Ollantaytambo, Puma Punku, Tiahuanaco, Machu Picchu and Sacsayhuaman, which of them is your favorite? And what would you add to our list of Inca and Pre-Inca constructions?
These are just some proof the incredible examples of ancient Inca and Pre-Inca skills. The question that still remains is… how did they do all of this, thousands of years ago? Are we looking at the product of advanced technology that has been lost since then? How did they cut, transport and place with such precision these incredible structures? Let us know what you think.

In 2007, astronomers discovered the Cosmic Horseshoe, a gravitationally lensed system of galaxies about 5.5 billion light-years away. The foreground galaxy’s mass magnifies and distorts the image of a distant background galaxy whose light has traveled for billions of years before reaching us. The foreground and background galaxies are in such perfect alignment that they create an Einstein ring.
NASA’s Lucy spacecraft has its next flyby target, the small main belt asteroid Donaldjohanson, in its sights. By blinking between images captured by Lucy on Feb. 20 and 22, this animation shows the perceived motion of Donaldjohanson relative to the background stars as the spacecraft rapidly approaches the asteroid.
High above Earth’s poles, intense electrical currents called electrojets flow through the upper atmosphere when auroras glow in the sky. These auroral electrojets push about a million amps of electrical charge around the poles every second. They can create some of the largest magnetic disturbances on the ground, and rapid changes in the currents can lead to effects such as power outages. In March, NASA plans to launch its EZIE (Electrojet Zeeman Imaging Explorer) mission to learn more about these powerful currents, in the hopes of ultimately mitigating the effects of such space weather for humans on Earth.
Seven planets grace the sky at the end of February in what’s known as a planetary parade, though some will be difficult to spot with the naked eye.
