New research has presented compelling evidence for the existence of a hypothetical 'Planet Nine' in the outer regions of our solar system, challenging previous skepticism. This potential planet, initially proposed in 2016 by Caltech researchers Konstantin Batygin and Michael Brown, is believed to exert gravitational influence on the orbits of distant icy bodies that intersect Neptune's path.

According to a recent report by the Indian Space Research Organisation (ISRO), the Chandrayaan-3 moon mission of India encountered a four-second delay during launch.

In a long-standing debate, experts discuss varied depression sub-types and genetic influences on stress reactions, challenging the reactive vs endogenous classification. Genetic risk impacts environment sensitivity, potentially affecting stress management strategies.

Climate change threatens biodiversity decline globally by mid-century, as land-use and climate changes lead to 2-11% biodiversity loss. Conservation, restoration, and natural solutions are crucial for safeguarding ecosystems.

A group of genes could be common to both depression and heart disease, a finding that researchers said could explain why having one of them increases risk of developing the other. The "puzzling" link between the diseases has been known to exist since the 1990s, they said. Studies have found that people with depression run a greater risk of cardiovascular disease, with early and effective treatment of the mental illness lowering the risk of developing heart-related conditions.

Doctors successfully implanted a pig kidney into a New Jersey woman, Lisa Pisano, who was teetering on the brink of death. This marked the culmination of a dramatic series of surgeries aimed at stabilizing her failing heart. Lisa Pisano faced a dire situation with both heart and kidney failure, rendering her ineligible for a conventional transplant and devoid of viable alternatives.
