A study of a type of stellar twin called W Ursae Majoris–type contact binaries that orbit each other closely gives new insights into how binary stars evolve and their eventual fate.   W Ursae Majoris (W UMa) stars are short-period, dumbbell-shaped binaries in which the two stars are in contact. They are so close, in fact, that they share a single outer atmosphere and they orbit around each other. These stars act as “natural laboratories” as they assist in precise determinations of fundamental stellar parameters such as masses, radii, and…

Scientists have developed the first supercomputer-powered simulations to capture the long existing paradox of water that had eluded scientists for long– hotter water freezing faster than colder water, a phenomenon technically called Mpemba effect. This research published in the journal Communication Physics can provide new insights into phenomena such as relaxation of materials due to sudden temperature changes technically called out-of-equilibrium phenomena and also can lead to diverse applications, such as giving a new perspective to thermal control in next generation electronic or defining better cooling strategies.   Aristotle, in…

MOIL has achieved best-ever production performance in FY 2025-26 (Apr-Dec), recording its best-ever production figures for both the third quarter and the first nine months of the financial year.   During Q3 of FY 2025-26, MOIL achieved a record manganese ore production of 4.77 lakh tonnes, registering a growth of about 3.7% over the corresponding period last year (CPLY). This is the highest-ever production achieved by the company in any third quarter since its inception.   Further strengthening this growth momentum, MOIL has also recorded its best-ever nine-month production of…
