The activity of ‘dark vessels’ – vessels that do not share their locations – hampers nations’ efforts to make fisheries transparent and accountable. Using cutting-edge satellite technologies, we uncovered the largest illegal fishing in history conducted by dark vessels in North Korea.

Tissue engineering allows us to transplant laboratory-made tissues into patients to save their life. But, regenerating large organs this way is challenging. As an alternative, we propose the organ transformation approach. An in-house spleen transformed into a liver-like organ was functional in mice, suggesting that this technology helps us overcome various challenges in tissue regeneration.

The Earth’s climate is a complex, dynamic system and understanding of how it evolves still poses challenges. In a new study, researchers simplified Earth to a model Aquaplanet – a land-free version of our planet – and discovered five climate scenarios.

Peculiar, luminous radiation called ‘fast radio burst’ is a spectacular event with mysterious origins. In a new study, researchers observed the first fast radio burst in our own Milky Way. This discovery proves that a star, called a magnetar, is indeed the source of this intense radio beam and challenges current theoretical models.

Instead of looking at visual maps, homing pigeons smell the environmental air to know their way home. Yet, how they achieve this spectacular feat remains mysterious. In a new study, we draw ‘olfactory maps’ that pigeons may use, identifying candidate odor compounds that likely navigate them homeward.

Rapidly rising atmospheric carbon dioxide (CO2) levels are accelerating climate change. Climate knock-on effects in response to the human-induced rise in CO2 in the Earth’s atmosphere have yet not played out and remain hard to predict. Detailed insights from an ice core record of past atmospheric CO2 substantiate the urgency to limit global warming to 1.5°C as agreed upon in Paris in 2015.
