When mobile phones first came into existence they were big and unattractive. Several researchers then worked on making them compact and desirable. People gradually warmed up to the technology and embraced it as it allowed them to communicate on the move. There have been several advancements since, catering to various demands of the users. A group of researchers has now developed a way to make the cell phone multipurpose – you can fold it up and keep it in your pocket or wallet, stretch the screen to make it a tablet, or wrap it around your wrist like a watch.

This next step in the development of digital displays has been made possible by researchers at the McKelvey School of Engineering at Washington University. Led by Chuan Wang, Assistant Professor in the Preston M. Green Department of Electrical & Systems Engineering, the researchers have developed a new material that has the best of both technologies — LEDs and OLEDs — and a novel way to fabricate it, using an inkjet printer. Their research has been published in the journal Advanced Materials.

The researchers used the inkjet fabrication method, instead of the traditional spin art method to create a particular type of crystalline material called an organometal halide (Omh) perovskite. This organic-inorganic compound makes the display flexible. From there, the Perovskite light-emitting diodes (PeLEDs) can be recovered.

“Because it comes in a liquid form, we imagined we could use an inkjet printer,” Wang was quoted in a release published on EurekaAlert. Also, inkjet fabrication saves materials as it deposits perovskite only where it’s needed. The process is much faster, cutting time from 5 hours to 25 minutes,” said Wang.

“Imagine having a device that starts out the size of a cellphone but can be stretched to the size of a tablet”.

These PeLEDs may be just the first step in an electronics revolution. They could make walls light up or even display the day’s newspaper. They can be used to make wearable devices, like a pulse oximeter to measure blood oxygen. Most excitingly, they can allow manufacturers to print stretchable devices.

Axiom 4 Mission Crew Settles Down at ISS, Begins Conducting Research

Axiom 4 mission’s crewmates began conducting biomedical research aboard the International Space Station on Tuesday. Expedition 73 and Ax-4 crews found electrical muscle stimulation and cellular immunity. The Cargo transfers and exercise gear maintenance take a day for orbital residents.

Takuya Onishi, Situation Commander from JAXA( Japan Aerospace Exploration Agency), has begun the shift in continuation of his space biology studies. His blood and saliva samples are being collected for storage and processing. Further, he spun the specimens in a centrifuge and placed the blood samples in the freezer. After that, he stowed the samples in the incubator.

JAXA’s Takuya Onishi Leads Cellular Immunity Study with Blood and Saliva Analysis

According to a report from NASA, the samples will be analysed to determine the effect of microgravity on cellular immunity, observe stress-related immune reactions, and learn about how to treat symptoms of immunity. The flight engineers Johnny Kim, Anne McClain, and Nichole Ayers spent their day on orbital lab maintenance and further support activities of the crew. Kim focused mainly on orbital plumbing as he replaced and drained the Tranquillity module.

Ayers checked cables and power components in the Destiny laboratory module and deactivated and placed the microscope. McClain took the cognition test on the laptop and kept on supporting the Ax-4 crew at a time of a busy schedule.

Ax-4 Crew Explores Muscle Stimulation and Space Suit Fabric Efficiency in Microgravity

Veteran astronaut Peggy Whitson and her Ax-4 crewmates Shubhanshu Shukla, Tibor Kapu and Uznański-Wiśniewski conducted numerous space investigations throughout the lab. The private scientists in their second full week on the station found out that the electrical muscle simulation escalates the space-related and muscle atrophy in space. Ax-4’s other experiments looked at suit fabrics promote thermal comfort with exercising the weightlessness, crew health and agriculture in space.

Sergey Ryzhikov and Alexey Zubritskiy worked together on the Zvezda service module, repairing and organising components on a treadmill, one of the two inside the space station, which included the COLBERT treadmill. Kirill Peskov started his day by going through the biological samples from the crewmates. At the end of his shift, he transfers water from Progress 92 cargo craft and unloads the stuffs of hardware and crew supplies.

Astronomers Discover 3I/ATLAS, Largest Interstellar Comet Yet Detected

Astronomers Discover 3I/ATLAS, Largest Interstellar Comet Yet Detected

Astronomers have discovered the third interstellar comet to pass through our solar system. Named 3I/ATLAS (initially A11pl3Z), it was first spotted July 1 by the ATLAS telescope in Chile and confirmed the same day. Pre-discovery images show it in the sky as far back as mid-June. The object is racing toward the inner system at roughly 150,000 miles per hour on a near-straight trajectory, too fast for the Sun to capture. Estimates suggest its nucleus may be 10–20 km across. Now inside Jupiter’s orbit, 3I/ATLAS will swing closest to the Sun in October and should remain observable into late 2025.

Discovery and Classification

According to NASA, in early July the ATLAS survey telescope in Chile spotted a faint moving object first called A11pl3Z, and the IAU’s Minor Planet Center confirmed the next day that it was an interstellar visitor. The object was officially named 3I/ATLAS and noted as likely the largest interstellar body yet detected. At first it appeared to be an ordinary near-Earth asteroid, but precise orbit measurements showed it speeding at ~150,000 mph – far too fast for the Sun to capture. Astronomers estimate 3I/ATLAS spans roughly 10–20 km across. Signs of cometary activity – a faint coma and short tail – have emerged, earning it the additional comet designation C/2025 N1 (ATLAS).

Studying a Pristine Comet

3I/ATLAS was spotted well before its closest approach, giving astronomers time to prepare detailed observations. It will pass within about 1.4 AU of the Sun in late October. Importantly, researchers can study it while it is still a pristine frozen relic before solar heating alters it. As Pamela Gay notes, discovering the object on its inbound leg leaves “ample time” to analyze its trajectory. Astronomers are now racing to obtain spectra and images – as Chris Lintott warns, the comet will be “baked” by sunlight as it nears perihelion.

Determining its composition and activity is considered “a rare chance” to learn how planets form in other star systems. With new facilities like the Vera C. Rubin Observatory coming online, researchers expect more such visitors in the years ahead. 3I/ATLAS offers a rare chance to study material from another star system.

NASA's New Horizons Proves Deep-Space Navigation via Stellar Parallax

NASA’s New Horizons spacecraft carried out an unprecedented deep-space star navigation test while 438 million miles from Earth. Using its long-range camera in April 2020, it captured images of Proxima Centauri and Wolf 359, which appeared slightly shifted in the sky compared to Earth’s view – a striking demonstration of stellar parallax. It was the first-ever demonstration of deep-space stellar navigation. By comparing these images to Earth-based observations and a 3D star chart, scientists calculated New Horizons’ position to within about 4.1 million miles, only about 26 inches across the United States.

Stellar Parallax Test

According to the paper describing the results, accepted for publication in The Astronomical Journal, New Horizons’ camera imaged Proxima Centauri (4.2 light-years away) and Wolf 359 (7.86 light-years) on April 23, 2020. From the spacecraft’s distant vantage point, the two stars appear in different positions than seen from Earth – the essence of stellar parallax. By comparing those images with Earth-based data and a three-dimensional map of nearby stars, the team worked out the probe’s location to within about 4.1 million miles.

As lead author Tod Lauer explained, “Taking simultaneous Earth/Spacecraft images we hoped would make the concept of stellar parallaxes instantly and vividly clear”. He added, “It’s one thing to know something, but another to say ‘Hey, look! This really works!’”.

New Horizons and Future Missions

New Horizons, the fifth spacecraft to leave Earth and reach interstellar space, flew past Pluto and its moon Charon in 2015, sending home the first close-up images of those distant icy worlds. Now on an extended mission, the probe is studying the heliosphere.

New Horizons’ principal investigator Alan Stern called the parallax test “a pioneering interstellar navigation demonstration” that shows a spacecraft can use onboard cameras “to find its way among the stars”, in a statement. He also noted it “could be highly useful for future deep space missions in the far reaches of the Solar System and in interstellar space”
