British rock band Coldplay will be performing in India as a part of the Music of the Spheres World Tour in 2025. The band will reportedly perform in Mumbai. More details are awaited. However, Bookmy show unveiled a short teaser of their upcoming concert on Wednesday on its Instagram profile. The post showcases a motion image of the announcement of Coldplay's performance in Mumbai. The post drew instant reactions. A fan wrote, "Let's goo!!!" Another fan wrote, "Wohooo!" Another comment read, "Can't wait to be there with my yellows for life."

The festival was held to promote global development goals. The upcoming concert will mark Coldplay's
Scientists have unravelled a doughnut-like structure buried deep within Earth's swirling outer core of molten metal. The exciting discovery was reported in a new study published in Science Advances.
The discovery was made by a research team that analysed seismic waves generated by large earthquakes. The expert team included Professor Hrvoje Tkalcic, a geophysicist from the Australian National University. These waves travel through Earth, giving scientists information about its internal composition.
As Professor Tkalcic explained, the researchers focused on how these seismic waves were slowing down while passing through a certain portion of the outer core near its boundary with the mantle.
"By understanding the paths of those waves and their travel times, we reconstructed their journey through the Earth's outer core," he added.
These waves were slower, indicating that a torus-shaped, or doughnut-shaped, region within the outer core was orientated parallel to the equator. This finds a new layer of complexity to the structure at the interior of the Earth.
The authors of the study write, "Thermochemical inhomogeneities in the Earth's outer core that enhance our understanding of the geodynamo have been elusive. Seismic constraints on such inhomogeneities would provide clues on the amount and distribution of light elements in the core apart from iron and nickel."
"Here, we present evidence for a low-velocity volume within the outer core via the global coda correlation wavefield. Several key correlogram features with a unique sensitivity to the liquid core show variations with wave paths remarkably slower in the equatorial than polar planes. We constrain a torus structure at low latitudes with 2% lower velocity than the surrounding liquid outer core via waveform modeling. We propose a thermochemical origin for such a low-velocity torus, providing important constraints on the dynamical processes of the Earth's outer core," the author said.
