The Earth Is Leaking Gold: Scientists Stunned To Find Precious Metals Emerging From Core
A groundbreaking study of Hawaiian volcanic rocks shows that Earth's core is leaking gold and other precious metals to the surface. It's estimated that over 99.99% of the Earth's gold and precious metals, such as Ruthenium, are trapped in the metallic core, buried beneath 3,000km of solid rock, Science Alert reported. These valuable resources have been locked away since the planet's formation 4.5 billion years ago. The research has been published in Nature.
Recently, a team from the University of Gottingen conducted a study on Hawaiian volcanic rocks, employing advanced isotopic analysis techniques to detect trace elements. They found unusually high levels of a specific ruthenium isotope, which is more prevalent in the Earth's core than its mantle. This suggests that the lava material originated from deep within the planet.
"When the first results came in, we realised that we had literally struck gold! Our data confirmed that material from the core, including gold and other precious metals, is leaking into the Earth's mantle above," says geochemist Nils Messling of Gottingen University in Germany.
The study shows that Earth's core is less isolated than previously thought, with core material reaching the surface during volcanic eruptions, offering future research opportunities. Ruthenium isotopes could serve as a novel tracer for studying core-mantle interactions, according to the researchers. The analysis indicates that hundreds of quadrillion metric tonnes of superheated material from near the core-mantle boundary rise to form ocean islands like Hawaii.
Professor Matthias Willbold, co-author of the study, emphasised the significance of the findings: "Our findings not only show that Earth's core is not as isolated as previously assumed. We can now also prove that huge volumes of super-heated mantle material, several hundred quadrillion metric tons of rock, originate at the core-mantle boundary and rise to Earth's surface to form ocean islands like Hawaii."
The study's findings ALSO suggest that some of the world's gold and precious metal supplies may have originated from the Earth's core. However, researchers are still unsure if the core-leaking process observed in the study has been a consistent phenomenon throughout the planet's history. "Our findings open up an entirely new perspective on the evolution of the inner dynamics of our home planet," the study noted.

Astronomers Baffled By Mysterious Object Emitting X-Rays And Radio Waves In Milky Way
Astronomers have stumbled upon a perplexing celestial enigma within our very own Milky Way galaxy. An international team of researchers has reported the discovery of a peculiar object exhibiting a unique behaviour: emitting X-rays in sync with bursts of radio waves, all in a repeating cycle of approximately 44 minutes. According to the study published in the journal Nature, this unprecedented observation has led scientists to classify the object as unlike any known entity within our galaxy. Located 15,000 light-years away in a star-rich region of the Milky Way, this enigmatic object, dubbed ASKAP J1832-0911, could potentially be a highly magnetised remnant of a dead star, such as a neutron star or white dwarf. However, the possibility of it being an entirely new and exotic phenomenon remains on the table. View this post on Instagram A post shared by NASA Chandra X-ray Observatory (@nasachandraxray) "This object is unlike anything we have seen before," team leader and Curtin University researcher Zieng (Andy) Wang said in a statement. The serendipitous discovery occurred during a routine observation of a supernova remnant by NASA's Chandra X-ray Observatory. Researchers were taken aback when they detected X-ray emissions emanating from the same source as previously observed long-period radio transients, which are rare objects that cycle through radio signals over extended periods. The correlation between the X-ray and radio wave emissions, coupled with other unusual characteristics, has deepened the mystery surrounding ASKAP J1832-0911. The object's hyperactive phase, during which it emits noticeable X-rays, appears to last for about a month, followed by a period of quiescence. This intermittent behavior suggests that similar objects might be lurking undetected in other parts of the galaxy, waiting to be discovered. While astronomers have pinpointed the object's location, its association with the nearby supernova remnant remains uncertain due to the vast distances involved. Further investigations are underway to unravel the true nature of ASKAP J1832-0911 and to explore the possibility of uncovering more of these enigmatic objects scattered across the cosmos.

China develops laser telescope that can see objects as wide as a matchstick head from over a kilometre away
Chinese researchers have developed a laser system that can detect tiny text and fine details from a distance of 1.36 kilometres, a new study published in Physical Review Letters has revealed. The team from the University of Science and Technology of China tested a laser-based method that achieved a 14-fold improvement in resolution compared to traditional optical imaging using a single telescope. New method focuses on light patterns, not image clarity Instead of focusing directly on capturing an image, the team used a technique called active intensity interferometry. This method is based on how light interacts with a surface rather than what the object looks like. Unlike traditional telescopes that rely on self-luminous sources like stars, this system can detect non-luminous objects. Infrared lasers and dual telescopes power the system According to Science Alert, the system emits eight infrared laser beams across a specific point. Two telescopes capture the intensity of the reflected light. By comparing the signals from the telescopes and calibrating the laser beams, researchers were able to reconstruct an image of the target.

Researchers develop colon-targeted drug delivery system
Hyderabad: A team of researchers from Andhra Pradesh, in collaboration with scientists from Saudi Arabia and the UAE, has developed a novel drug delivery system for colon cancer using cross-linked nanoparticles derived from mastic gum (MG)—a natural resin. Tired of too many ads? go ad free now Their findings were published in 'Nature Scientific Reports' under the title 'Enhanced colon-targeted drug delivery through development of 5-fluorouracil-loaded cross-linked mastic gum nanoparticles.' The study, led by Nawaz Mahammed and T Reshma of Raghavendra Institute of Pharmaceutical Education and Research, Anantapur, centres on the targeted delivery of 5-fluorouracil (5-FU)—a widely used chemotherapeutic agent—directly to the colon. The goal is to maximise therapeutic efficacy while minimising systemic toxicity and off-target effects. Conventional oral formulations of 5-FU are prone to premature degradation in the upper gastrointestinal tract, limiting their utility for colon-specific cancers. Encapsulation efficiency The team formulated cross-linked mastic gum nanoparticles capable of encapsulating 5-FU and releasing it in a controlled, zero-order kinetic profile—ensuring a consistent and sustained release rate over time. The formulation demonstrated an encapsulation efficiency of 83.5%, with an average particle size of 240 nanometres. Importantly, 95.2% of the drug was released in a colon-targeted manner, underscoring the platform's promise for site-specific drug delivery. Characterisation techniques, including fourier transform infrared spectroscopy, confirmed successful cross-linking of the MG, while scanning electron microscopy revealed uniformly spherical nanoparticles—features that contribute to the system's stability and targeting precision. Tired of too many ads? go ad free now Among the various formulations evaluated, the cross-linked MG nanoparticles emerged as the most effective, demonstrating both structural integrity and optimal drug release characteristics. The study underscores the therapeutic potential of this approach in enhancing the efficacy of chemotherapy for colorectal cancer while reducing systemic exposure and associated side-effects.
