Scientists have observed a new microscopic mechanism enabling precise control of the magneto-optical properties of excitons in alloys of two-dimensional semiconductors. This discovery opens up tangible prospects for technological applications in devices exploiting valleytronics. The research findings were published in the journal Physical Review Letters.
For about six months, NASA’s Curiosity Mars rover has been exploring a region full of geologic formations called boxwork, low ridges standing roughly 3 to 6 feet (1 to 2 meters) tall with sandy hollows in between. Crisscrossing the surface for miles, the formations suggest ancient groundwater flowed on this part of the red planet later than scientists expected. This possibility raises new questions about how long microbial life could have survived on Mars billions of years ago, before rivers and lakes dried up and left a freezing desert world behind.
New observations of Ganymede reveal a striking similarity between the auroras on the largest moon in the solar system and those on Earth. The international team of astrophysicists, led by researchers from the University of Liège, has produced new results indicating that, despite different conditions, the fundamental physical processes that generate auroras are common to different celestial bodies, and not just planets.
Our solar system hosts almost 900 known moons; more than 400 orbit the eight planets while the remaining orbit dwarf planets, asteroids, and Trans-Neptunian Objects (TNOs). Of these, only a handful are targets for astrobiology and could potentially support life as we know it, including Jupiter’s moons Europa and Ganymede, and Saturn’s moons Titan and Enceladus. While these moons orbit two of the largest planets in our solar system, what about moons orbiting giant exoplanets, also called exomoons? But, to find life on exomoons, scientists need to find exomoons to begin with.
Light powers everything from communications to sensing, yet even tiny imperfections can scatter it and weaken signals. To address this, a team led by the University of Bath—working with the University of Cambridge and international partners—has developed a new structure that keeps light flowing smoothly even through bends, twists or damage, with the potential to operate over unprecedented distances.

Using NASA’s Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new exoplanet orbiting a distant star known as TIC-65910228. The newfound alien world is slightly larger and nearly five times more massive than Jupiter. The discovery was reported in a paper published Feb. 13 on the arXiv pre-print server.

More and more papers are coming out about the upcoming Habitable Worlds Observatory (HWO). As the telescope moves from theory to practice (and physical manifestation), various working groups are discovering, defining, and designing their way to the world’s next major exoplanet observatory.
The collaboration of TU Wien with research groups in China has resulted in a crucial building block for a new kind of quantum computer: The realization of a novel type of quantum logic gate makes it possible to carry out quantum computations on pairs of photons that are each in four different quantum states, or combinations thereof. The advancement is an important milestone for optical quantum computers. The study has now been published in Nature Photonics.

CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and build up its intensity. Once the intensity is high enough, researchers can perform unique light operations.
Retired Navy Lt. Commander Alex Dietrich, a veteran combat pilot, gave an eye-witness account of a Tic Tac UFO. Dietrich spoke to Anderson Cooper about what she saw off the coast of San Diego in 2004. At the time, she was on a routine training mission off the USS Nimitz aircraft carrier 100 miles southwest of San Diego. Lt. Cmdr. Alex Dietrich and Cmdr. Dave Fravor, a graduate of the TOPGUN naval flight program, also appeared on 60 Minutes to discuss what they saw together. They both described an “unsettling” experience with a Tic Tac UFO.
Strangely, the Tic Tac-shaped UFO had no exhaust plumes, markings, or apparent means of propulsion. Notably, both pilots reported their sighting in a debriefing but didn’t think there was any formal investigation at the time. Behind them, each pilot had a weapons system officer in the seat, who each witnessed the UFO. Unsettling, Unexplainable EncounterOn November 14, 2004, Dietrich and her fellow crew gave “thorough debriefs” about the sighting minutes after landing. Furthermore, hours after landing, Dietrich says she gave a written account about the UFO. Years later, she gave even more details in what she calls an “interrogation-style” interview to members of Navy intelligence and the Advanced Aerospace Threat Identification Program (AATIP). Dietrich was a new pilot flying with the VFA-41, also known as the “Black Aces.” That day, she was flying a F/A-18F as part of an exercise to intercept and identify a “real-world contact,” after command redirected her squadron. When the pilots arrived at the specified coordinates, it looked like something the size of a Boeing 737 had crashed, creating roiling whitewater.
Suddenly, her heart-sinking feeling changed into the surprise of a lifetime. Unpredictable MovementAll of a sudden, instead of the expected search and rescue effort, something extraordinary happened: a UFO that closely resembled a white Tic Tac appeared.
Notably, Fravor’s account on 60 Minutes was somewhat different:
According to their observations, the aircraft was about the size of an average aircraft fuselage.

Meanwhile, an “uncomfortable and inexperienced” Dietrich (as she put it) fell back to give cover, circling above as Fravor approached. When Fravor’s fighter moved forward, the Tic Tac abruptly disappeared. All the while, the stunned pilots discussed what was happening on their radio.
According to Fravor’s account, the Tic Tac began mimicking his moves as if aware of his presence. 60 Miles in SecondsSeconds later, the USS Princeton’s radar reacquired the location of the Tic Tac UFO 60 miles away. Furthermore, the ship’s radar had also detected “multiple anomalous aerial vehicles” descending 80,000 feet in less than a second. According to CBS News, the pilots later found out the USS Princeton had been tracking UFOs for days. However, the pilots were left uninformed and unarmed.
In all, the strange encounter lasted about five minutes.

However, she says she’s “not qualified to make the analysis.” Although she isn’t sure what the UFO could be, she appeared to encourage other pilots to come forward. Even so, she may not have come forward at the time if she had been the only witness.
Notably, both Fravor and Dietrich had endured “ribbing” from their fellow crew about their reports. Today, she says everyone can contribute to a data pool of sightings.
By contributing their UFO reports, the veteran combat pilot hopes that intelligence analysts and scientists can use the data to draw “reasonable, rational conclusions.” Today, the pilots say they have no idea who was responsible for the Tic Tac UFO. We All Want AnswersAfter finally coming forward with her account, Dietrich says she’s seen many camps of people fascinated by her story. Thus, UFO enthusiasts, debunkers, conspiracy theorists, and religious fanatics have all shown interest on Twitter. Unfortunately, they seem intent to fight each other as much as getting to the truth.

Over the past few decades, researchers have worked to rigorously demonstrate such advantages, ideally in ways that are provable, verifiable and experimentally realizable.
