NASA confirmed the asteroid 2025 PN7 as a “quasi-moon” of Earth, meaning it follows a similar orbital path around the Sun but is not gravitationally bound to our planet like the Moon. Discovered by the University of Hawaii in 2025, PN7 is estimated to be between 18 and 36 metres in diameter. Its orbital behavior makes it appear as if it accompanies Earth in its journey around the Sun. NASA’s analysis confirmed that PN7 poses no danger to our planet, making it an exciting scientific discovery for understanding near-Earth objects.

India has developed Nafithromycin, its first homegrown antibiotic, aimed at treating resistant respiratory infections, especially in vulnerable patients. This achievement, alongside successful indigenous gene therapy trials for hemophilia, underscores India’s growing capabilities in biotechnology, pharmaceutical innovation, and clinical research. These breakthroughs were enabled by collaborations between the Department of Biotechnology and private firms like Wockhardt, reflecting a strong public-private partnership. Additionally, India’s progress in genome sequencing and precision medicine positions the country as a rising leader in healthcare innovation, reducing dependence on foreign technologies and advancing its goal of biotech self-reliance under the Viksit Bharat 2047 vision.

Chandrayaan-2, launched by ISRO in 2019, made the first direct observation of how Coronal Mass Ejections (CMEs) from the Sun impact the Moon’s exosphere. The CHACE-2 instrument on board recorded a significant increase in the density of neutral atoms and molecules, confirming that solar outbursts can dramatically alter the lunar atmosphere. This finding enhances understanding of lunar space weather, especially because the Moon lacks a global magnetic field and atmosphere, making its exosphere highly sensitive to solar activity. Chandrayaan-2’s observations contribute valuable data for future lunar missions and planetary science research.

Google developed the AI model Cell2Sentence-Scale 27B (C2S-Scale), a 27-billion-parameter foundation model designed to interpret the language of individual cells. This breakthrough enables researchers to generate AI-driven hypotheses for biomedical research, accelerating the discovery of potential cancer treatments. The model’s predictions were experimentally validated, making it one of the first instances where AI directly contributed to scientific discovery rather than solely analyzing data. This innovation demonstrates the growing role of advanced AI models in transforming healthcare research and providing new approaches for understanding complex cellular mechanisms.
