A species of snake once thought lost to science has been rediscovered in the forests of Barbados. The Barbados threadsnake , believed to be the world's smallest snake, was spotted during an ecological survey in March 2025 by ecologist Connor Blades and his team. The official announcement and detailed confirmation were only made public on July 23, 2025, through a press release by Re: wild and the Barbados Ministry of EnvironmentThe elusive reptile, just about 10 centimetres long and 2 millimetres wide, hadn't been officially seen in nearly two decades.'It hasn't been seen in basically two decades, so it was quite an exciting find,' said Blades, a project officer with the Ministry of Environment in Barbados. 'Probably one of the highlights of my career so far.'The snake was found beneath a small rock in a forested area, one of the last patches of relatively natural woodland left on the island. Its tiny size and worm-like appearance often lead to it being mistaken for an earthworm. It is blind, feeds on termite eggs, and lives underground, making it hard to spot.So far, scientists have only documented the species a handful of times since 1889. After being wrongly classified for years, US biologist S. Blair Hedges officially identified it as a distinct species in 2008.A microscope confirmed the snake's identity at the University of the West Indies. Key markings, including faint dorsal lines, helped distinguish it from other similar species, such as the Brahminy blind snake, an invasive species in Barbados.A month after the first sighting, another Barbados threadsnake was found in a different location, further boosting hopes for its survival.The rediscovery was part of a long-running effort under the Conserving Barbados' Endemic Reptiles project, in collaboration with Re:wild , an international conservation group.Since European colonisation, Barbados has lost 98 per cent of its natural forests. The threadsnake's survival in the remaining forest pockets highlights the urgent need to protect what's left.'It reminds us that we still have something important left that plays an important role in our ecosystem,' said Justin Springer of Re: wild.Barbados has increased its overall tree cover over the past decades, but natural, moist forests, the threadsnake's preferred habitat, remain rare. Conservationists hope the rediscovery will guide future efforts to protect endangered species on the island.'If the threadsnake population isn't very dense, I'm worried about their ability to find mates, particularly if their habitat is under threat,' said Blades.

Scientists stunned by discovering fast-spinning stellar object that defies physics
Long Period Radio Transient Q: What makes neutron stars or white dwarfs different from normal stars? Q: Why is spin-up behavior considered unusual for these objects? Unexpected spin behavior defies expectations Scientific implications and future research Live Events Q: What is a Long Period Radio Transient (LPT)? Q: What is circular polarization in radio waves? (You can now subscribe to our (You can now subscribe to our Economic Times WhatsApp channel Astronomers have discovered a highly unusual and rare object—a fast-spinning Long Period Radio Transient (LPT) dubbed CHIME J1634+44—that challenges current understanding of stellar remnants and physics. This extraordinary celestial object exhibits a combination of features never before observed, spinning up rather than slowing down, and emitting highly circularly and linearly polarized radio bursts , prompting new questions about its nature and J1634+44 belongs to a little-understood class of objects called Long Period Radio Transients (LPTs). Unlike most pulsars or neutron stars that spin rapidly with rotations measured in milliseconds or seconds, LPTs have extremely long spin periods ranging from minutes to hours. Remarkably, CHIME J1634+44 is the only known LPT observed to be spinning up, meaning its rotation period is decreasing—its spin is accelerating rather than slowing as expected for stellar stars and white dwarfs are dense stellar remnants left after massive stars exhaust their fuel and collapse. Neutron stars are incredibly compact, made mostly of neutrons, while white dwarfs are less dense but still very compact. Both can emit radiation and rotate, but their behavior stellar remnants gradually lose rotational energy and slow down due to magnetic braking and radiation loss. A spin-up indicates something is adding energy—such as matter being pulled from a companion star or a contracting orbit—suggesting unusual physical conditions or dynamics in the stellar remnants, such as neutron stars or possibly white dwarfs, usually lose rotational energy over time and slow down gradually. However, CHIME J1634+44's rotation period is shortening, defying this typical behavior. Scientists theorize that this might imply the object is part of a binary system with a shrinking orbit, possibly due to gravitational wave emission or intense gravitational interactions, although no definitive cause has yet been the radio bursts it emits are either nearly 100% circularly polarized or strongly linearly polarized depending on the pulse phase, a phenomenon unprecedented among known neutron stars or pulsars. This suggests the source or mechanism generating these radio waves is fundamentally different from typical pulsar emission peculiar physics of CHIME J1634+44 open new avenues in understanding stellar remnants like neutron stars and white dwarfs. Its spin-up behavior and unique radio wave polarization challenge existing models of stellar magnetospheres and rotation. Scientists are investigating whether it is a binary system where orbital decay is spinning up the object, or if new, unknown mechanisms are at this object could shed new light on stellar remnant evolution, gravitational wave sources, and the physics of extreme magnetic fields. The findings are expected to have implications for astrophysics , especially regarding how exotic stellar remnants behave in binary systems and under extreme conditions.A Long Period Radio Transient (LPT) is a mysterious type of astronomical object that emits periodic bursts of radio waves at unusually long intervals—ranging from minutes to hours. Unlike typical pulsars, LPTs rotate very slowly and are still poorly understood by polarization occurs when radio waves' electric fields rotate in a spiral as they move through space. It's rare in natural emissions and indicates highly organized magnetic environments. In CHIME J1634+44, the presence of circular (and linear) polarization suggests a unique and powerful emission mechanism.

Scientists discover 400-mile-long chain of fossilized volcanoes buried beneath China
Formation and geological significance Methodology and findings Broader implications Live Events (You can now subscribe to our (You can now subscribe to our Economic Times WhatsApp channel Researchers have uncovered a massive, 400-mile-long chain of extinct, fossilized volcanoes deep under South China , revealing a surprising new chapter in Earth 's geological history. This ancient volcanic arc formed around 800 million years ago during the early Neoproterozoic era , when two tectonic plates collided during the breakup of the supercontinent Rodinia, according to a recent study published in the Journal of Geophysical Research: Solid 800 million years ago, South China sat on the northwestern margin of Rodinia. Shifting tectonic forces caused the landmass, now known as the Yangtze Block, to break off and move toward the China Ocean plate. This collision caused the denser oceanic crust to subduct beneath the continental crust — a process that generated magma as the oceanic plate heated up and released water. The magma rose through the crust, forming a long volcanic arc along the subduction typical narrow volcanic arcs seen along continental margins (such as the Cascade Range in North America), this chain is unusually broad, stretching approximately 430 miles (700 km) long and about 30 miles (50 km) wide, extending as far as 550 miles (900 km) inland. This extensive width is linked to a tectonic process called flat-slab subduction, where the oceanic plate moves horizontally at a shallow angle beneath the continent before descending deeper. This shallow subduction produces two volcanic ridges—one near the plate boundary and another further inland—explaining the wide spatial extent of the fossilized volcanic arc beneath the Yangtze fossil volcanoes erode over millions of years and become buried under thick sedimentary layers (up to several kilometers thick in the Sichuan Basin), they are challenging to detect. The research team, led by Zhidong Gu (PetroChina) and Junyong Li (Nanjing University), employed airborne magnetic sensing technology to map magnetic minerals beneath these sedimentary layers, revealing iron-rich rocks with strong magnetic signals consistent with volcanic arc magmatism approximately 4 miles (6 kilometers) below the taken from seven deep boreholes drilled in the Sichuan Basin showed geochemical signatures similar to crust formed by volcanic arcs, and uranium-lead dating confirmed that these magmatic rocks formed between 770 million and 820 million years ago, placing them firmly in the early discovery has significant implications for understanding Earth's crustal evolution. Volcanism and related mountain building in arc systems create new crust and alter existing crust. The volume and extent of magmatic activity revealed by this study suggest that ancient volcanic arcs were more extensive than previously realized in this Peter Cawood from Monash University, who was not involved in the study, pointed out alternative possibilities, such as the idea that the two volcanic belts revealed might be separate, contemporaneous systems joined together later in geological time. Nevertheless, he emphasized that the study provides "exciting new data" in a traditionally difficult-to-study area.
