World's first soft robots that can walk straight out of the machines

1 week ago | techexplorist.com | Amit Malewar

Soft machines, made from flexible materials such as soft plastics, could be beneficial in fields like nuclear cleanup, medicine, and space exploration. However, their real-world use has been limited due to high costs, complex manufacturing, and a lack of standard designs. Scientists at the University of Edinburgh have created the first soft robots that can walk straight out of the machines that manufacture them.
Moon’s magnetic mystery solved? Why are some rocks on the moon highly magnetic?

1 week ago | techexplorist.com | Amit Malewar

For decades, scientists have been puzzled by a puzzling phenomenon: the moon, despite having no inherent magnetic field today, holds rocks infused with powerful magnetism. Now, a new study from MIT researchers proposes a groundbreaking explanation: ancient lunar impacts, not just a global dynamo, might have significantly shaped the moon’s magnetic anomalies.
Infrared contact lenses help us see in the dark

1 week ago | techexplorist.com | Amit Malewar

Humans can’t see infrared light because of the way our eye proteins work. However, seeing invisible infrared light with the naked eye would be incredibly useful. Scientists have developed cutting-edge contact lenses that allow humans and mice to see infrared light without the need for night vision goggles or bulky equipment. The innovation transforms invisible infrared wavelengths into visible light, allowing wearers to simultaneously perceive infrared and natural light.
What sources caused the reionization of the Universe?

1 week ago | techexplorist.com | Amit Malewar

Understanding the Universe’s evolution is an essential aspect of modern astronomy. The reionization era was a mysterious early phase of the Universe when no stars or galaxies existed, and space was shrouded in a thick fog of hydrogen gas. Then, the first stars formed and emitted powerful radiation, gradually clearing the fog and allowing light to travel freely. Astronomers are still working to understand what produced enough energy to lift this cosmic haze and make the Universe transparent.
Astronomers observe a pair of galaxies in a deep-space battle

2 weeks ago | techexplorist.com | Amit Malewar

For the first time, astronomers have observed a violent galactic duel in which one galaxy uses a quasar to bombard another with intense radiation, impeding its ability to form new stars. This discovery, detailed in Nature, offers unprecedented insight into how galaxy collisions and supermassive black holes influence cosmic evolution.
An extraordinary dwarf planet discovered at the edge of our solar system

2 weeks ago | techexplorist.com | Amit Malewar

Researchers have identified a new trans-Neptunian object (TNO) named 2017 OF201, an icy world that lurks beyond Neptune’s orbit in a breakthrough that reshapes our understanding of the outer solar system. Led by Sihao Cheng of the Institute for Advanced Study, the discovery suggests that the space beyond the Kuiper Belt, once considered nearly empty, may instead be home to a hidden population of distant planetary bodies.
Claiming life too soon? Doubts arise over K2-18b’s biosignature

2 weeks ago | techexplorist.com | Amit Malewar

In April, an announcement electrified the scientific community: Researchers had detected dimethyl sulfide (DMS), a molecule associated with biological life, in the atmosphere of exoplanet K2-18b. If confirmed, it could be one of the most tantalizing hints of alien life ever found. But a new study led by University of Chicago scientists is stifling the excitement, arguing that the data is too noisy to make such a groundbreaking claim.
Jupiter was once twice as prominent with a supercharged magnetic field

2 weeks ago | techexplorist.com | Amit Malewar

Jupiter’s early formation shaped the structure of the Solar System, influencing its overall development. However, the exact timeline of its formation remains uncertain due to gaps in current models, making independent studies essential for a better understanding. A new study reveals that about 3.8 million years after the Solar System began forming, Jupiter was much larger and had a stronger magnetic field than it does today.
Generative AI can outperform humans in emotional intelligence tests

2 weeks ago | techexplorist.com | Amit Malewar

AI models can excel in many fields, but their ability to understand emotions is still unclear. Researchers from the University of Geneva and the University of Bern tested six AIs, including ChatGPT, using human emotional intelligence (EI) assessments. Surprisingly, the AIs performed better than the average human and even quickly created new tests, suggesting exciting AI potential in education, coaching, and conflict resolution.
Scientists demonstrated microwave-driven singlet-triplet qubits

2 weeks ago | techexplorist.com | Amit Malewar

Hole spin qubits are gaining popularity in quantum processors because they operate quickly and efficiently using only electric signals. Their strong spin-orbit interaction makes control easy but leads to inconsistencies, meaning qubit properties vary across different locations. While these variations allow precise control of individual qubits, they must be carefully managed to ensure the system can scale effectively.
