Astronomers Discover Why Massive Galaxies Died Early in the Universe
Astronomers have discovered a powerful galactic wind in the merging galaxy system CRISTAL-02. The outflow is removing star-forming gas faster than it can be replenished, providing the first direct evidence for a mechanism that may have shut down star formation in massive early galaxies.

Astronomers Detect Star-Forming Fuel in a Galaxy 13 Billion Light-Years Away
Using ALMA and the Very Large Array, astronomers directly detected a massive reservoir of molecular gas in REBELS-25, a galaxy from just 700 million years after the Big Bang. The finding provides the clearest evidence yet that some early galaxies were already loaded with the fuel needed for rapid star formation.

Astronomers Discover Two Galaxies That Appear to Lack Dark Matter
Researchers studying FCC 224 and FCC 240 in the Fornax Cluster found evidence that both galaxies contain surprisingly little dark matter. The discovery supports the idea that galaxy collisions can strip away dark matter and raises new questions about how galaxies evolve.

James Webb Space Telescope Weighs Most Distant Dormant Black Hole Ever Detected
Using JWST and a natural gravitational lens, astronomers measured a six-billion-solar-mass dormant black hole more than 10 billion light-years away. The discovery offers a rare glimpse into how galaxies and black holes evolved when the universe was just three billion years old.

Kangana Ranaut Calls Indian Nurses' Uniform "Very British", Is That So?
Kangana Ranaut recently called for the 'Indianisation' of what she described as 'very British' nurses' uniforms. However, healthcare dress codes in India have evolved significantly since Independence, with scrubs now emerging as the most common attire.

Are Some Cancers Worse Than Others? What Scientists Say
Scientists say some cancers are biologically more aggressive than others, but outcomes depend on many factors including tumour type, stage, genetics, treatment response, and early detection.

Scientists Discover 77 Rare Red Quasars Hidden Behind Cosmic Dust
Scientists have discovered 77 rare red quasars hidden behind cosmic dust using NASA’s SPHEREx telescope. The findings support theories linking galaxy mergers to rapid black hole growth and galaxy evolution.

Why Does Every Human Voice Sound Different? Scientists Explain
Over time, humans lost the vocal membranes and air sacs found in monkeys and apes and developed a more stable voice box.

Brown Dwarf Merger Could Create a New Star, Astronomers Discover
Astronomers have discovered a rare brown dwarf binary system undergoing mass transfer with an ultra-short orbit. The pair could either merge or gain enough mass to ignite fusion, potentially forming a new star and redefining how “failed stars” evolve.

A Desert Full Of Whales: Egypt's Window Into Evolution
What makes Wadi al-Hitan extraordinary is the type of fossils found here. The valley contains the remains of Archaeoceti, an extinct group of early whales that still retained traces of their land-dwelling ancestry.

Dating Out Of Your League? New Study Says It's A Tale As Old As Time
A study said that Neanderthal men and human women were particularly inclined to mate, a sexual habit that offers insight into the evolution of the modern human genome.

Scientists Uncover "Ghost Genes" That Predate The Dawn Of Life
New research into "universal paralog" genes reveals that the Last Universal Common Ancestor (LUCA) was not the first spark of life, but a successor that inherited complex genetic tools from an even older, "pre-LUCA" ecological system.

New ALMA Images Reveal Complex Rings Left Behind by Planet Formation
Astronomers used ALMA to capture unprecedented images of young exoplanetary systems. The ARKS survey mapped 24 debris disks, revealing rings, gaps and collisions that trace planetary evolution. These snapshots expose chaotic transitional stages, helping scientists understand how newborn planets mature into stable systems like our own Solar System t...

Hubble Reveals How Blue Straggler Stars Stay Young in Ancient Clusters
Astronomers using the Hubble Space Telescope have uncovered new clues to the mystery of blue straggler stars—unusually hot, bright stars found in ancient globular clusters. By studying ultraviolet light from 48 clusters, scientists discovered that blue stragglers are more common in sparse clusters, supporting the idea that they form through binar...
