Why Nataraja Statue Stands At CERN: India’s gift meets particle physics

3 hours 18 min ago
In 2004, India presented CERN with a statue of Shiva Nataraja, a powerful symbol of cosmic creation and destruction. This statue serves as a metaphor for the essence of scientific exploration. At CERN, researchers delve into the universe's tiniest components and its earliest moments, viewing Shiva's dance as a representation of the ever-changing behavior of subatomic particles, weaving together ancient mythology and contemporary scientific knowledge.

A rotating 'garbage island' spreads over 1.6 million sq km in the Pacific with 50 kilograms of plastic per square kilometre

4 hours 15 min ago
Between the shores of Hawaii and California floats a staggering 1.6 million square kilometers of plastic debris. This island of waste includes not just nets and ropes but also countless microplastics that pose serious threats to marine wildlife. Animals often mistake plastics for food, while others become trapped in ghost fishing gear.

Meet Zainab Nathani, the Illinois student who designed a solar water-harvesting material

7 hours 5 min ago
Zainab Nathani has created a groundbreaking solar-powered material capable of drawing potable water from the moisture in the air. This remarkable innovation garnered her recognition at the Regeneron International Science and Engineering Fair. Additionally, she established a program to support the development of clean water wells abroad. Nathani’s work elegantly fuses scientific advancements with dedicated advocacy for accessible water worldwide, aiming to tackle critical water access issues.

African honeyguides recognise honey hunters' calls to help find hidden bee nests

9 hours 55 min ago
In Africa, wild honeyguides have showcased their remarkable ability to identify specific human calls, making them indispensable allies for honey hunters searching for concealed bee nests. Recent studies reveal that these birds are more responsive to local calls than to those from outsiders. This finding implies the evolution of a sophisticated communication system honed through generations, facilitating the birds' survival by guiding them to beeswax.

In the 1990s, a predatory flatworm was released in Samoa to control giant African snails

18/08/2026
The introduction of the invasive flatworm, Platydemus manokwari, aimed at pest control, has resulted in a dramatic decline of native tree snail populations in the Pacific Islands. This aggressive predator actively hunts these snails, driving several species towards extinction. Following previous unsuccessful biological control attempts, federal data now labels these native snails as endangered or threatened, prompting strict biosecurity measures to halt the invasion of this detrimental species.

In 1885, New Zealand introduced hedgehogs to fight pests; today, they threaten native wildlife

18/08/2026
European hedgehogs were brought to New Zealand during the 1800s to help manage garden pests. However, these spiky creatures now pose a grave danger to the country's unique wildlife. They feast on the eggs and young of various native species, significantly impacting fragile ecosystems, particularly those involving ground-nesting birds. As a result, ongoing conservation initiatives are prioritizing hedgehog removal to protect these threatened populations.

Scientists find fire salamanders glow blue-green under UV light from secretions

18/08/2026
Under ultraviolet light, adult fire salamanders reveal a captivating blue-green fluorescence generated by their skin secretions, lasting for several hours. This striking luminescence is mainly concentrated in areas rich in glands, especially along their flanks and underside. Researchers propose that this unique trait could serve functions in communication or as a warning signal, enhancing our understanding of the fire salamander's biology.

Have we found first exomoon? Strange object forcing astronomers to rethink what a moon is

18/08/2026
Astronomers have found strong evidence for a massive object orbiting a brown dwarf. This object behaves like a moon, circling another body which orbits a star. Researchers are calling it an exosatellite due to its host's unusual nature. This discovery marks a significant step towards confirming the first exomoon. Future observations will determine its definitive classification and implications.
