The twin of the Milky Way galaxy found in the distant Universe

1 week ago | techexplorist.com | Amit Malewar

Large spiral galaxies, like the Milky Way, were thought to take billions of years to form. In the Universe’s first billion years, galaxies were expected to be small and chaotic. However, the James Webb Space Telescope (JWST) shows a different story. Its deep infrared images reveal surprisingly large and well-formed galaxies much earlier than expected, causing astronomers to rethink how and when they formed in the early Universe.
A giant rocky planet could be shrouded in a thick, hot atmosphere

1 week ago | techexplorist.com | Amit Malewar

Sub-Neptunes are the most common type of planet in the galaxy but are absent in our solar system, making them intriguing. Scientists are especially interested in temperate sub-Neptunes, as some might be habitable. In the habitable zone, these planets were believed to be massive ocean worlds with hydrogen-rich atmospheres, known as “Hycean” worlds, like K2-18 b.
Brain's "ventral stream" might be more versatile than previously thought

1 week ago | techexplorist.com | Amit Malewar

The brain processes visual information using two pathways that handle different tasks. Scientists have long believed that one of these, the ventral visual stream, evolved specifically to recognize objects. Supporting this idea, MIT researchers found that computational models optimized for object recognition closely match the ventral stream’s neural activity. However, a new study shows that when these models are trained on spatial tasks instead, they also align well with ventral stream activity.
NASA's Webb focuses on dying star energetic display

1 week ago | techexplorist.com | Amit Malewar

Using NASA’s James Webb Space Telescope, scientists have detailed the gas and dust expelled by a dying star in NGC 1514. Its rings, discovered in 2010, were once invisible but are now revealed in infrared light as tangled “fuzzy” clumps. Fast-moving material near the central stars has punched through, forming clear holes. This scene has evolved for over 4,000 years and will continue changing for thousands more.
Mystery solved: Why do carbon-rich asteroids rarely become Earth meteorites?

1 week ago | techexplorist.com | Amit Malewar

Carbonaceous meteorites hold a special place in science—they contain water and organic molecules, vital ingredients linked to the origin of life on Earth. Despite their importance, these meteorites are surprisingly scarce. Although more than half of all meteoroids in space are predicted to be carbonaceous, only about 4% of meteorites recovered on Earth fit this category. So, why the discrepancy?
UNIGE scientists uncovered the brain circuit behind Autism-related social challenges

1 week ago | techexplorist.com | Amit Malewar

Human connection is the foundation of survival and development. Yet, for children with autism spectrum disorders (ASD), this ability is often compromised from an early age, as they show limited interest in social stimuli within their first year of life. Delayed cognitive development in ASD often stems from a lack of understanding of social interactions. Children with ASD have less interest in social cues early on, which hinders their ability to acquire tools for navigating the social world.
Game-changing hybrid anode paves the way for advanced energy storage

1 week ago | techexplorist.com | Amit Malewar

Combining transition metal oxides with carbon-based materials through engineered chemical interfaces improves conductivity, storage capacity, and stability, boosting energy storage system performance. Dongguk University researchers have significantly advanced lithium-ion battery technology by creating a new hybrid anode material.
A new type of quantum entanglement discovered

1 week ago | techexplorist.com | Amit Malewar

In an exciting breakthrough, researchers at Technion have uncovered a novel form of quantum entanglement in photons confined to nanoscale structures—a leap forward with the potential to revolutionize quantum communication and computing. Their discovery delves into the mysterious world where light particles are no longer just “photons” but become entangled in their total angular momentum, revealing properties never seen before.
Black hole awakens with historic X-Ray storms

1 week ago | techexplorist.com | Amit Malewar

Supermassive black holes are challenging to observe because they can stay dormant for long periods. This was the case for the black hole in galaxy SDSS1335+0728, 300 million light-years away in Virgo. After decades of inactivity, it suddenly became active, emitting powerful X-ray bursts. The galaxy SDSS1335+0728, which had remained stable for 20 years, began showing increased optical brightness in December 2019.
Researchers finally discovered antiferromagnetism in quasicrystals

1 week ago | techexplorist.com | Amit Malewar

Quasicrystals (QCs) have a unique atomic arrangement that lacks periodicity, giving them unusual symmetries not found in regular crystals. Scientists have been exploring their quasiperiodic magnetic properties and potential uses in spintronics and magnetic cooling areas. Recently, researchers identified ferromagnetism in gold-gallium-rare earth (Au-Ga-R) icosahedral quasicrystals (iQCs). This finding wasn’t unexpected, as ferromagnetism can occur without periodicity.
